Title: [ANN] Bitcoin blockchain data torrent
Post by: jgarzik on February 20, 2013, 03:55:14 PM
This is a torrent of the publicly available bitcoin blockchain data.

IMPORTANT NOTE:  As of Bitcoin Core version 0.10.0 or later, this torrent is slower than a direct download using the bitcoin P2P protocol & client.  This torrent is now only maintained for research and development purposes as a secondary option.  Please use Bitcoin Core directly to download the blockchain.

Bitcoin-Qt/bitcoind version 0.7.1 and later supports a special import feature:  If the file "bootstrap.dat" is found in the bitcoin data directory, it will validate and import all blockchain data found in that file.  The following torrent presents a bootstrap.dat file for that feature.

Here is the PGP-signed torrent information.  The public key for jgarzik@bitpay.com may be found at public keyservers or http://bitcoin.org/jgarzik-bitpay.asc   Details follow below the signature.

What is bootstrap.dat?

It is a flat, binary file containing bitcoin blockchain data, from the genesis block through height 317,000.

Versions 0.7.1+ automatically validates and imports a file in the data directory named "bootstrap.dat".

Special note: Version prior to 0.8.0 have a bug which will only import 2G of data from a file.  This is fixed in 0.8.0.


Who wants bootstrap.dat?

Anyone bringing up a new node using the reference client.  This is one method of accelerating the initial blockchain download process, while helping the bitcoin P2P network by offloading data download traffic from public P2P nodes.

This download is not for those who are already running the bitcoin client.


How often will this torrent be updated?

Assuming this project is deemed useful and worth continuing... the torrent will be updated once every few months, when the checkpoints are updated in the reference client source code (https://github.com/bitcoin/bitcoin/).


Why not update the torrent more often?

A torrent works best when it is a large, static dataset that changes infrequently.  That maximizes the ability to seed the data, enabling even part-timer seeders to contribute meaningfully.  Less frequent changes also minimizes the risk that a malicious torrent will appear, with a long, malicious side chain.  The current policy only updates the torrent after blocks are buried many thousands deep in the chain.


Why should I trust you?

You don't have to:  This data is raw block chain data.  The client will verify this data during import.

Independent third parties may generate their own bootstrap.dat, up to height 317,000, and verify that the sha256sum matches that posted above.  The file format is simple and publicly known:

     <4-byte pchMessageStart><32-bit length><CBlock, serialized in network wire format>


Torrent file download?

If the magnet link does not work, download the torrent file from https://bitcoin.org/bin/block-chain/   http://gtf.org/garzik/bitcoin/bootstrap.dat.torrent

How can I help?  Do you need more seeds?

Yes, we need as many long term seeds as possible.  This ensures we can meet torrent download demand immediately at high speeds, and remain idle the remainder of the time.


Generate the file myself?

You may generate the file yourself, rather than downloading it, if you have Bitcore Core and python.  The tool used to generate bootstrap.dat is https://github.com/bitcoin/bitcoin/tree/master/contrib/linearize


Comments welcome

Post any comments or experiences in this thread.  I'll update the OP as needed.

Direct download mirror: https://bitfetch.com/static/bootstrap.7z (https://bitfetch.com/static/bootstrap.7z)
(compressed using 7z/LZMA2 - 2.7 vs. 4.7 GiB)

If you can seed, use the torrent instead.

I was seeding the previous version (2.3 GB, share ratio 15) and when I added this one, it picked up and verified the existing version and continued downloading from 51%. Very cool!

This is a great idea, although I am a bit confused as to the future as we won't all need to keep a full node anymore, but I'm sure that will come into understanding in the coming weeks. 

Seeding this as much as possible!

How to find the data directory (where this file belongs to):
https://en.bitcoin.it/wiki/Data_directory (<-- this also needs a bit of updating for the different files/folders with 0.8)

Some more hash values of this bootstrap.dat file (up to 216116):
Adler32: FA0EEF4C
CRC32: DDF59E6B
MD5: 1B437D44213B7D98C974546B55834D10

Unfortunately it's not possible (yet?) in Bittorrent to share HTTP seeds in a swarm (DDoS potential!), but still - if you have a web server to seed this file but cannot run Bittorrent, you might still post a link here, so you can be added to the Magnet URI/torrent file.
HTTP seeds are in most clients actually quite rarely used, so unless people start to direct download from these you might not even have heavy traffic going on.

Also if you cannot use Bittorrent, there are services around that download torrents for BTC for you and offer a HTTPS download link. I won't link these here as I don't want to make it look like I endorse any of these.

This is not a replacement for block data you already have.  This is a separate file, that is only used once, during data import.

After data import, the file is renamed to bootstrap.dat.old, and never touched again.  Most will want to manually delete it, after use.

More specifically answering the question, if your Bitcoin client is already close to block 216116 (January 11) or even halfway completed (block 190000), the bootstrap.dat likely won't be of much use to you. It may take more time to download and then import the torrent than to complete the blockchain synchronization normally. This torrent is also only for those using the v0.8.0 release or after, as 0.7.1-0.7.2 are not able to import more than 2.0GiB of the 4.7GiB file.

You can use the bootstrap.dat torrent with no ill effects regardless of your current block. When you restart and Bitcoin sees the bootstrap.dat that you have dropped in it's data directory, any block hashes you already have will be skipped quickly, and the import will pick up at the blocks you don't have.

I have an up-to-date copy of the blockchain.  Is there an easy way to generate bootstrap.dat from it so I can seed it without having to download the whole thing again?

I'm thinking it might be relatively easy to modify the armory source code to dump out a bootstrap.dat file, but won't bother if something already exists.

This script is used to generate bootstrap.dat:
https://github.com/jgarzik/pynode/blob/master/mkbootstrap.py

It requires an up-to-date pynode chain database.

In theory, someone could write a script that processes bitcoind's $DATADIR/blocks directory into bootstrap.dat, but no one has written that yet.

They have now...

https://gist.github.com/dooglus/5002764

It uses the Armory code to do all the work, and creates a bootstrap.dat with the correct sha256 hash:

Post by: coblee on February 21, 2013, 08:21:14 AM
I've tried a few times and couldn't get this to work. First time, I just put the bootstrap.dat file there and tried to run it against my current blocks. It didn't like that and got stuck.

The next time, I deleted all my block data and tried it again. This time it got stuck at block 211551 (iirc) and wouldn't load any block after that. Looking at the debug.log, I see that my peers are trying to give me blocks higher than that but my client keeps rejecting them for some reason.

The third time, I tried the same thing again. This time, when it got to block 155088, it gave me a database corrupt message and the client quit. Restarting the client does the same thing:
init message: Importing blocks from block database...
LevelDB read failure: Corruption: block checksum mismatch

I'm running this on a Mac if that makes a difference. Seems like 0.8 is buggy.

 I ll try to update it whenever a new torrent and checkpoint comes out
( also seeding the torrent )

 OP: perhaps you should setup a mailing list for mirrors, so you can ping us all when a new version of the torrent have to be downloaded ?

I'm sure this has been discussed before, but I couldn't find it: Why isn't a (moderately up-to-date) bootstrap.dat (optionally) included with the offical bitcoind/bitcoin-qt binaries? The trust model isn't invalidated because (a) you're downloading binaries and (b) the bootstrap's data are verified. Sourceforge already hosts the blockchain. It seems it would remove a lot of redundant data transfer from the bitcoin network, no?

This is special to our use case:  bootstrap.dat is essentially an append-only file.  Blocks are simply concatenated onto the end.

((...snip...))

The next torrent, a few months from now, will have the same first 2,491,771,562 bytes.

Thus, to bittorrent, the next torrent will simply appear to be a truncated / not fully downloaded bootstrap.dat.  Bittorrent is built to fill in the missing pieces of a file, so that is what it does here :)

I just copied that over from the beta thread

... wanted to point out that it DID work for me

(I was able to use the older/smaller/earlier bootstrap.dat, and then my bittorrent client was able to smartly "fix" the new torrent... like...
the smaller file is basically the same & I only needed to download the missing end. This procedure results in the same updated bootstrap.dat
)

... it should continue to work for the next new/larger/updated torrent just the same.

thanks jgarzik, you rock :)

Me: Uploaded 23.05 GB

When there are 40 seeds (there were up to 60 earlier), you only need to give one downloader 1/40th of 4.7GB, and it will be less if you have a slower connection then the fastest seeds. The three peers I have connecting from Netherlands, Russia, and Iran are barely getting data, they might be mistakenly using their 2400 baud modems to get the torrent.

Make sure you have encryption enabled (many will block if you don't), and the TCP/UDP ports of bittorrent and DHT port forwarded.

There tends to be bursts, with idleness following.  There are many seeders, so download-then-idle is quite fast.

It has the most impact in handling unintended bursts, like when bitcoin sees a lot of new press attention.

I use transmission too and it's not rare for me to see other files uploading at hundreds of Kb/s, but I don't see a lot of interest in bootstrap.dat either. However there's little I can do besides seeding so…

Hi Jeff,

I create some quicks steps to get this from the command line in Ubuntu / Debian:

Code:
$ sudo aptitude install rtorrent
$ rtorrent -n -d ~/.bitcoin/ "magnet:?xt=urn:btih:6fe493ba606847eac163baf35aae9db319735482&dn=bootstrap.dat&tr=udp://tracker.openbittorrent.com:80&tr=udp://tracker.publicbt.com:80&tr=udp://tracker.ccc.de:80&tr=udp://tracker.istole.it:80"

I'm not sure if the bootstrap.dat needs to go in .bitcoin or in .bitcoin/blocks/.

All the best,
D

PS: A little OT but I see pynode is a listen only client is there something in python like pynode that handles all bitcoin operations?

Feedback on this is welcomed.  Generally, not all platforms have an easy time getting up and running with 7zip.  Users in the past requested something directly usable with bitcoind.

Opinions differ, and maybe if it saves a gigabyte or two, it would be worth it.

Some users also complain about the doubling of disk space required -- for both compressed and uncompressed copies.



Title: Re: [ANN] Bitcoin blockchain data torrent
Post by: Sukrim on May 28, 2013, 09:40:55 PM
I would keep it uncompressed for the time being - it would be great by the way if bitcoin-qt would delete the file after a successful import automatically, I'm sure that some still keep it around unnecessarily. I see the issues with it suddenly "disappearing" but I guess the benefit of not wasting space outweighs it.

I don't care if I seed now ~4.5 GB or ~3 GB, as long as compression doesn't change the file size really significantly (meaning 5 instead of 50 or 500 GB) I rather consider it a burden than helping. There are download sources for compressed blockchain files already on the web anyways.

With 0.8.2 around the corner, can we expect a new check point + torrent file by the way?

It saves more than 3GB currently; 7zip at optimum settings reduces blockchain data to about 57% of the original size.

It would reduce the amount of disk space required; the decompressed copy doesn't need to be kept after an import. The compressed file is seeded from the user's torrent directory, and makes for a good checksummed archive of the blockchain for a user to have as a backup too.

I wrote unzip/install scripts that can be included with the torrent for one-click extraction

http://(deleted)...


....
I am slowly convincing myself even more that a compressed torrent is preferable. Without compression you are downloading the same amount of data as normal p2p. The compressed binary would only be repeatable on the exact xz/lzma/7zip build version and settings, but I think there are probably four people total that have run mkbootstrap (https://bitcointalk.org/index.php?topic=130066.msg1400898#msg1400898) anyway, so this is not important. It takes about an hour to smash the blockchain down to 60% the size at the extreme settings I've used over many trials to optimize settings.

Compressed-Pros:
-2000+ 3000+ MB of uploading and downloading saved for every user,
-2000+ MB less storage used when seeding,
-won't cause problems if torrent HDD is FAT32
(another: small split files easier to host/share/download from multiple sources than a single 8GB file)

Compressed-Cons:
-Not as simple to use, end-user must decompress with third-party utility (although 7-zip is common),
-More work creating torrent (doesn't matter to end-users),
-Cannot "update" torrent by simply replacing data file with newer version with additional blocks (likely to be a rare practice anyway, I am the only one seeding the old torrent right now).

Here is example compression, both require about an hour (but decompress in minutes):

xz utils 5.0.4/Win64, 3GB+ RAM required to compress (2,780,285,148 bytes)
xz --compress --keep --format=xz --check=sha256 --verbose --lzma2=dict=256MiB,nice=273,mf=bt4 bootstrap.dat

7-zip GUI win64 - 6GB+ RAM required to compress (2,769,830,975 bytes)
Format: 7z, Compression Level: Ultra, Compression method: LZMA, Dictionary size: 384MB, Word Size 273

A checkpoint of 225430 was added two months ago at the fork. I would guess that this will either be updated to a newer block or another will be added to before 0.8.2.

I added them but I'm afraid I can only leave the torrent up for 12 hours (I'm going to Australia tomorrow).

I couldn't contact exodus.desync.com (no ping) but picked up a couple of peers from the other two instantly.

When was this last updated?

block 216116, it is 240000+ today

I am assuming the compressed bootstrap.dat differs in the headers (1st MB) and whatever is appended at the end.
So I guess you need to byte compare the first chunk and the last chunk to check my assumption?

A file compressed with 7zip is a solid archive with a very large dictionary. Extracting any part of the file requires the data that came before it; essentially you must have the complete 7zip archive to extract data. A multipart 7zip archive is not independent files, the parts are just a binary split of the whole large archive file, and downloading later parts without the first part is useless. You must have all 7zipped compressed data in order to extract a verifiable bootstrap.dat.

A future torrent created with multi-part 7z files instead of one big uncompressed bootstrap.dat means that you could supplement your download or seeding by getting some of the torrent multi-part files off different websites where they might be hosted, and manually adding them to the torrent.

I am disappointed that 0.8.2 was released without a new checkpoint. Current block is 240709, I could force the issue by creating a block 0-240,000 bootstrap.dat torrent, if many would choose to adopt and seed such a torrent as a new "official" one. I'll see if Gavin is interested in picking a new checkpoint block yet with a code pull.

I am disappointed that 0.8.2 was released without a new checkpoint.
https://github.com/bitcoin/bitcoin/blob/master/src/checkpoints.cpp
Latest checkpoint: 225430

There is no need for multipart other than the 4 GB/file limit on FAT32 maybe. Most modern torrent clients already support HTTP sources too and would download pieces from these only when there are not enough seeders around in the swarm. As you already said, once a new torrent gets released, all previous data in case of 7zip is invalidated so it is not a case of "I ass another 200 MB piece and the previous ones are still valid" as it is with an uncompressed chain file.

In other news, I announced to these other trackers too, though switching on DHT should already give enough peers to connect to the rest of the swarm via peer discovery - trackers are rarely used these days any more other than for bootstrapping and maybe connecting swarms that were split. Once there is even a single peer connected to both parts of a swarm, via PEX they will be soon reunited anyways. The desync.com one is offline for me too by the way.

@jgarzik:
Could we (until you decide on whether to compress or not) at least have an "official" bootstrap.dat torrent until 225430 (or ideally: ~240k)? I mean it's not that hard to create one ourselves, it would just lead to more fragmented swarms and just having a single "official" one makes it easier to seed.

I would suggest the following scheme by the way:
Every 4032 blocks (= 2 difficulty changes or ~every 4 weeks) release a new torrent link for current block - 2016 (so the block of the last difficulty change). This should be by far deep down enough to not be part of any chain splits any more and updating a link every 4 weeks (or just getting it from an RSS feed) should be not too much hassle for seeders either.

If you set the part size in the torrent to a certain fixed size, you could even let people come up with the info hash programmatically just by processing their own chain files!

Yes, the blockchain torrent will be updated this week (probably today).

As others have noted, if you compress with 7zip, that eliminates a useful property from the current torrent:  The first X gigabytes are the same in the old bootstrap.dat torrent, and any new bootstrap.dat torrent.  Using the same file, and replacing the .torrent file, will cause your torrent client to download only the new blocks, not the entire torrent.

Updated torrent.  See OP for full information.

The torrent is directly available from http://gtf.org/garzik/bitcoin/bootstrap.dat.torrent but ideally the magnet should find it.

As with other updates, simply replace (delete) the old .torrent with this new .torrent.  Any existing bootstrap.dat will be appended, avoiding a lengthy download process for the first ~200,000 blocks.

Please seed this new torrent (and drop the old)!

Without a tracker URL, it looks like rtorrent does not want it.
Would you mind if I published a torrent.dat with some common public trackers?

Well, if it is truly a problem, I would prefer to regenerate the .torrent file.

What are everybody's favorite trackers?  IRC also reports a couple trackers listed in the magnet link are down.

Ideally the DHT should find things, but trackers seem to be necessary for some clients.

Edit: rtorrent users should turn on the DHT.

OK, updated torrent file at SourceForge and http://gtf.org/garzik/bitcoin/bootstrap.dat.torrent to add trackers mentioned upthread.

Same info hash (thus, same bootstrap.dat file data).

Once enough peers have this new torrent, the magnet link should pick it up for the rest.

I want to host the blockchain on a cloud server and then point about 50 raspberry pi's to it. Is there a way to do this?

1. Cloud server - no. To have even marginal performance, blockchain files would need to be on a local network drive. The blockchain database works much better on SSD than rotational hard drive. You would be using something much slower than a standard hard drive and sharing it with 50 computers.

2. Rasberry Pi, no. So much slower than a used $25 craigslist computer.

3. The blockchain torrent can be imported into one system's bitcoin-qt. The complete data directory (except wallet.dat) could be copied to other machines so you don't have import multiple times.

4. Then SOME of the blockchain files that never change could be moved to a network drive and replaced with symbolic links on the client filesystems. The only files that won't be changing are past BLK00001.dat-BLK00064.dat files in the blocks sub-directory. The most recent BLK000xx.dat file must not be copied to network, it will still be added to by the individual client bitcoins and must be local and unique to that bitcoin.

Your question appears to have nothing to do with the bootstrap torrent.

I was just wondering if people would find it usefull if there was a website that did the following:
  • Provide one big button to download a torrent of a recent version of the blockchain
  • Offer an alternative download (zipped)
  • Show the number of active seeders
  • Post a new torrent on a weekly basis (or some other viable interval) automaticly based on a bootstrap.dat maintained by a node running on the server.
  • Provide information to verify the integrity of the download

That's when I saw this thread :). Just downloaded the bootstap.dat in 18 minutes!

What do you think, will there be enough users of a service like this? Or will a solution like this thread in combination with a 6 month interval suffice?

    If you keep updating the file it will break people seeding it and so you'll never have a big distribution network.

      I am using Bitcoin Qt 0.8.3 Beta, so it should support auto-import of this file, right?

      Just a little unsure of where to put it, and if I need to delete the folders "blocks" and/or "Chainstate" and the files "db.log", "debug.log" or "peers.dat"?

      I am on OSX so presume that it is going somewhere inside the /Users/will/Library/Application Support/ folder?

      I think Jeff's is just the 'safe' way, or for if you are running an older version of Bitcoin-QT...


      If anyone else gets stuck like me, what I did was:

      OSX using Bitcoin-QT versions 0.7.1+

      1) Open a terminal window
      2) Open a finder window.
      3) In the finder window, navigate to /Applications/ and the ctrl+click on 'Bitcoin-QT' and choose 'Show package contents'
      4) Navigate to /Contents/MacOS/ and then drag the file in there ('Bitcoin-QT') into the terminal window
      5) add a space into the terminal window, after the 'Bitcoin-QT' file, then type:

      -loadblock=

      So in the terminal window you will have something like this:

      "Your-iMac:~ user$ /Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -loadblock="

      Dont press anything else yet...

      6) Next, with the finder window selected again, navigate to the location of your 'Bootstrap.dat' file
      7) Drag this file into the terminal window, so that it adds it onto the end of the command, which will look something like:

      "Your-iMac:~ user$ /Applications/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -loadblock=/path/to/file"

      Hit enter to run.

      Hope that this helps someone else :)

      Post by: jgarzik on August 01, 2013, 06:48:06 PM

      Simply dropping bootstrap.dat into the folder is the safe, easy way.  After the import is complete, the file is renamed to ensure it is not re-imported over and over again.

      -loadblock is fine too, but requires a bit of extra work on the part of the user.



      Title: Re: [ANN] Bitcoin blockchain data torrent
      Post by: e4xit on August 01, 2013, 10:16:19 PM
      Will Bitcoin-QT versions 0.7.1+ recognise that the file is there automagically without having to run the binary with the parameter '-loadblock='?

      Also, just out of interest, does Bitcoin-QT import the blocks from disk using just a single CPU core?

      I am just wondering as I have an i7 (3.1 GHz) CPU, but activity monitor doesn't show more than 70% CPU (max is 800%)... If it is single core, is there any way to increase this?

      Updated block chain torrent to height 250,000, coinciding with a recently commited checkpoint in the bitcoind source code.

      Existing seeders, please update by simply swapping out the old torrent file for the new torrent file.  After restarting your torrent client, you should already have ~85% of the new bootstrap.dat.

      New seeders:  We always need more seeders, in every country of the world, to help spread the block chain and speed downloads.  Ideally, we have a large swarm of seeders, that burst to downloads at maximum download speed, and then remain idle the rest of the time.

      Read the OP for magnet link and torrent details.  Ask questions.

      This tool may be used to recreate bootstrap.dat byte-for-byte identical with the bootstrap.dat in this torrent.

      Edit: Check here: https://en.bitcoin.it/wiki/Data_directory
      Where do I want to paste it,
      The database directory?

      Nop, paste it in the main directory, then start Bitcoin-QT it should detect the file and start importing.

      Nope, copy the bootstrap.dat file into the Bitcoin database directory, the same directory that contains your wallet.dat file. When you restart Bitcoin-qt, it will import all blocks from the bootstrap.dat that weren't previously downloaded.

      Well, that's the main directory:

      $ ls .bitcoin/
      blocks  chainstate  database  db.log  debug.log  peers.dat  wallet.dat

      I've seeded already in total for sure above 100 GB. :)

      Would be great to have a new check point and also a new torrent soon. We're already ~18k blocks further down the road after all.

      Please also consider creating an RSS feed that one can then subscribe to, once enough people do this, you can even swith to faster releases, as new torrents will be seeded much faster.

      The checkpoints are hard-coded into the Satoshi client. New checkpoints can only happen at new releases of said client. Once that's released (or at least committed to the repo -- the timing is up to Jeff) a new torrent will presumably be made.

      I'm beggining to think Bitcoin-QT should download the torrent itself!

      Well, sipa (Pieter Wuille) is working on implementing headers-first syncing, where the client will start by downloading all the block headers from a peer, and once that's done, the downloading of block data can happen in parallel from multiple peers at once, making bootstrap.dat much less needed.

      This tool may be used to recreate bootstrap.dat byte-for-byte identical with the bootstrap.dat in this torrent.

      You can create the bootstrap.dat with pynode. It will get it's own copy of the blockchain from a single IP (your own bitcoin), and you can then create the file with mkbootstrap.py.

      Will bitcoin-qt only recognize a bootstrap.dat file starting at block 1?

      is it possible to use the python util to create a new bootstrap.dat starting at block 250001 ? For example - to update an off-line PC which has only had previous access to the 250k bootstrap.dat.

      Creating a new 10gb+ file up to 270k+ seems silly when I only need to create the difference between the two (and easier to transfer to off-line PC).

      Thanks.

      Bitcoin 0.8.5 has a checkpoint block in it at 250,000 and less checks are done when downloading or importing blocks before this point. After block 250,000, download/sync/import speed is usually CPU-limited.

      Bitcoin looks for any file named bootstrap.dat when it starts up, imports the blocks from it, and renames it. If the blocks are duplicates, it will ignore them. If the blocks are unseen and continue from the last block, it will import them.

      The linearize python script does not appear to have a method to accept a starting block height. I was not sure if Bitcoin-QT would recognize a bootstrap file not starting at block height 1. But it seems it does. This appears to work -


      Quote
      def get_blocks(settings):
              rpc = BitcoinRPC(settings['host'], settings['port'],
                               settings['rpcuser'], settings['rpcpass'])

              outf = open(settings['output'], 'wb')

              for height in xrange(settings['max_height']+1):
                  if height > 249999:
                      sys.stdout.write(str(height) + "\n")

      It generated a 3GB bootstrap between 250-270k which Bitcoin-QT accepted.

      What's a "cancer" node?

      Backfilling the network with clients controlled by an attacker. The attacker nodes are called cancer nodes. Always up full nodes create constant connections that resist this type of attack. If the attack network was large enough clients starting up briefly to only make one or two transactions may only connect to cancer nodes. This would effectively create two networks. Thin clients are booted up briefly to perform transactions then closed. Too many thin clients supporting the network (running briefly and closing) create an environment for this attacks success. I run a full node 24/7/365 to ensure I always connect to the "real" network.

      I have zero trust in my bank but every transaction will not need to be verified throughout history. I only keep credit card receipts and bank statements for so many years. Why is the preservation of spent outputs so important that we will continue to allow them to make Bitcoin-Qt unwieldy? I would mind this less if I could see security enhancements that truly protect thin client or zero confirm transactions but I don't.

      No, that's not true. You have 100% trust in your bank to hold your money for you. The bank says "you have this amount of money", and you believe that number. You don't control the money, the bank does.

      On the other hand, Bitcoin *is* zero-trust. If you run Bitcoin Core, you're validating every piece of transaction information that you receive, and not trusting or believing anything just because someone tells you it's correct.

      No, you're completely incorrect. A bank tells YOU that you have that amount of money and YOU believe that number. I do not.

      Bank records and statements are accounting methods that need to be checked against your own records. If you're doing what I hope your mommy and daddy taught you when they helped you set up that shiny new first bank account, you are keeping a record of transactions (money you've spent and deposited) and reconciling that against the statement you receive from the bank each month. There is a tool I like to call a "checkbook register" to help you perform this task. That will ensure that the bank is keeping accurate records of your account and allow you to correct errors with the bank should you find an error or fraud against your account (zero trust). I have found errors in my account in the past, challenged my bank and they immediately corrected the error. If they fail to correct the error and you know they are wrong (because you don't trust them and keep your own record) you can still have the error corrected by using another tool I like to call "an attorney" to correct the error. Here is a fairly cheap book that can help you with a basic understanding of these concepts: http://www.barnesandnoble.com/listing/2691051713384?r=1&cm_mmca2=pla&cm_mmc=GooglePLA-_-Book_15To24-_-Q000000633-_-2691051713384

      Record keeping should always be questioned even in Bitcoinland. However, there is a point in record keeping when the information (check register) is no longer valuable. That point is after reconciliation when the transaction is complete, it has been checked by both parties, those parties are in agreement and the information is not required for audit. It is then safe to dispose of your ledger and move on. I opened my first bank account (with the help of my mommy and daddy) in 1968. I no longer keep records of my transactions for that account because I would like to store automobiles in my garage instead of boxes of ledgers and they are unnecessary.

      Bitcoinland banks which are uninsured and must be trusted completely are called "Wallet Services": inputs.io, MyBitcoin, Blockchain.info etc. Online banks that are insured to $250,000 of loss and deal with fiat are just called "banks" and include: Capital One 360, USAA, Flagstar, ally etc.

      I guess you mean "more current", not "actual"?

      Anyways, the latest check point in bitcoin's source code is from block 250000, this is what this torrent contains. If you want a more recent checkpoint, feel free to create a pull request with a more recent hash, I guess we could have an updated torrent then as well.

      I don't know how soon 0.9 will be released, most likely it will contain a more recent check point and this topic will be updated.

      Still it doesn't import all the blockchain and need a day or more to get it fully updated. Isn't there a way to add an automatically updating torrent (or a program uploading a new one every few days).


      Title: Re: [ANN] Bitcoin blockchain data torrent
      Post by: Sukrim on January 04, 2014, 09:33:59 PM
      There could be an RSS feed, usually torrent clients assume that a new item there is a completely new file though, so it would not build upon existing data and lead to a lot of redundant downloads between seeders over time. Also a concern is that there might not be enough seeders anyways, if the file changes every few days (though that's not really a concern with RSS feeds...). Also verifiability of the file might be a bit more difficult, this one is quite proven compared to something that changes often.

      I guess with recent improvements (header first sync) a lot of downloading issues of the client will anyways be gone, so I'm unsure if it would pay off to invest time into a better solution for bootstrap.dat files instead of just waiting for the next bitcoin-qt release that has the potential of coming up to sync very fast anyways.

      Just a thought off the top of my head... thinking of an advanced bittorrent protocol where the torrent content data can be dynamically updated. For example the original publisher of the torrent could change the contents, and any clients seeding would recognise the changes, download them and continue seeding. The original uploader could prove their identity by having a unique private key for the torrent and sign a message with the changes.

      Something like this would allow something like this bitcoin torrent to be regularly updated without requiring switching from an old torrent to a new one.

      Does anything like this already exist?

      Bittorrent inc acts like huge jerks regarding open source development on that one though.

      Otherwise bittorrent is really intended for static files, just imagine first offering a popular file and then switching it out for something illegal or something containing a backdoor or virus as soon as it gained traction.

      It might be worth the time and hassle to decompile btsync and document their inner workings, to implement a open source version of it or something similar. After all it is mostly a way to share info hashes with certain nodes on the dht as far as I get it.

      a Tracker e.e. tracker.bitcoin.org would be good or a magnetlink on sourceforge

      can an Admin put an actual bootstrap.dat.torrent on SFG ? the version there is from 08/2013. my Client say 41% after import and need to download 59 % from network.

      The latest torrent file is always available at http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/

      We don't want to run a tracker ourselves..  that introduces a centralize, single point of failure.

      Just a thought off the top of my head... thinking of an advanced bittorrent protocol where the torrent content data can be dynamically updated. For example the original publisher of the torrent could change the contents, and any clients seeding would recognise the changes, download them and continue seeding. The original uploader could prove their identity by having a unique private key for the torrent and sign a message with the changes.

      Something like this would allow something like this bitcoin torrent to be regularly updated without requiring switching from an old torrent to a new one.

      Does anything like this already exist?

      This already happens with torrents, at least this torrent... When a new download for this torrent becomes available, simply choose to download to the location you still have your old "bootstrap.dat" file, you torrent client will 'verify' the first 'x'% of the data, up until the point new data is found. Then continue the download from there.

      I have done this myself and can verify that it works.

      This might only be applicable to certain data formats, for example the blockchain is extremely sequential, and data is only ever appended to the end of the file (AFAIK). But I do not know much about this an am open to correction on this matter from those who do.

      Note: If you have used bootstrap.dat to import block data before it will be renamed to "bootstrap.dat.old" (or something similar). If you want to perform this little 'trick', make sure it has the name "bootstrap.dat" (the same as the torrent). Would also be prudent to ensure you have bitcoind/QT shutdown while you do this, in case it start trying to import while you download or whatever.

      Just pointed my NL-hosted seedbox to this torrent so should have some more fast uploaders now anyway...

      I know that bitcoin has been growing a lot but mine loaded about 20-25% of the blocks with my bootstrap.dat and then stopped to switch to "synchronizing with network." Soonafter my bootstrap file was renamed to .old so I figured it was done...that bootstrap is about a half a year old, has 75% of the bitcoin trading really been in the last 6 months???

      I would not trust your and/or seed this file, also there are already a number of sites where you can download a more recent copy of the block chain anyways.

      But I do not know much about this an am open to correction on this matter from those who do.
      As I said, to do this automatically, yuo need to use Bittorrent Sync, which uses BT technology but is currently closed source and in heavy development.

      you didnt need to trust because  bitcoind/bitcoinqt would trust them or not... , so he would trust downloaded blocks......

      Please publish the SHA256 & MD5 of the final bootstrap.dat file that you created to 279000. I will be able to tell you if it can be independently created by others with identical data. I can recreate jgarzik's from network-downloaded blocks.

      Blockchain data is fully signature-checked for all blocks since the last code checkpoint. This means that CPU, and not network bandwidth, is usually the limiting factor processing blocks 250,000 and on. It is not really beneficial to download more data before getting the Bitcoin CPU work started, which is why the torrent corresponds with the checkpoint.

      Suggestions for better trackers are always welcome.  Trackers appear and disappear, and I'm certainly not an expert on picking them.

      Ideally we would use trackerless torrents (pure DHT), but that early experiment ended in failure.

      It may mean the message we are getting at the browser is not the message Jeff signed.

      If this is the case, then there often winds up being an innocent explanation for it, such as that forum software is introducing unwanted line-breaks into the message, or something like that. But at worst, it may mean someone has altered the message.

      Quick question: if we have already synced up to 279k blocks with our qt wallet, can we use your bootstrap_279000_up.dat file by itself
      to update the remaining blocks?

      Or do we also need the entire bootstrap.dat additionally with previous blocks?

      Thanks for your help!

      EDIT:  This does work with the partial bootstrap file. I just had to make sure to re-start the wallet after adding the bootstrap file.
      Normally, I would be waiting for hours get these last 4k blocks synched in the wallet, now its just taking a few minutes.
      Thanks for the bootstrap file!!!

      Place bootstrap.dat in the bitcoin data directory and then start Bitcoin-Qt. It will read the file to create the blockchain. The file will be renamed to bootstrap.dat.old when this is completed to prevent reprocessing when Bitcoin-Qt is restarted.
      You can locate the data directory by reading this (https://en.bitcoin.it/wiki/Data_directory).

      You can use the bootstrap.dat torrent with no ill effects regardless of your current block. When you restart and Bitcoin sees the bootstrap.dat that you have dropped in it's data directory, any block hashes you already have will be skipped quickly, and the import will pick up at the blocks you don't have.

      Forgot to mention...  the following python util, linearize.py, was checked into the bitcoin repo today:

           https://github.com/bitcoin/bitcoin/tree/master/contrib/linearize

      This tool may be used to recreate bootstrap.dat byte-for-byte identical with the bootstrap.dat in this torrent.

      If you are running bitcoind locally, create bootstrap.dat locally, then start seeding the torrent immediately at 100%!

      The problem with these torrents is that the peers can be seeding out of date versions.  People have to manually notice an updated torrent and go download that instead.  If we used Bittorrent Sync  (http://www.getsync.com) then a highly trusted member of the community could have the main 'secret' and everyone else who just wants to download can have the 'read-only secret'.

      In fact that trusted member can also share it with a couple of other trusted members, so that any of a small group of people could update the bootstrap.dat, whereas the usual peers could only get the updates.

      Like this, the file can just be updated and all the peers will notice and update their copy, downloading only the chunks that are different/new.  No new torrent needs to be distributed or freshly seeded.

      Yes.  bitcoin.org will be the new official site.  It was "soft launched" (without announcement) as I was travelling and did not have time to adequately test, and then make updates.

      It is also about time to roll another torrent.

      I've also been considering adding a second torrent, which contains blocks/blk*.dat as you might find created by Bitcoin Core.  New installations could download this blk*.dat torrent, restart with "-reindex" option.  This will perform a zero-trust revalidation of all data, while eliminating the redundant copy of the bitcoin data (vs. bootstrap.dat).

      Could someone explain why it is preferable to seed a torrent of the blockchain rather than just run a bitcoin full node? I run a full node and it sends between 500GB to 1TB a month of data to at least 70-95 connected clients. Yes, I opened port 8333 on the firewall/router.

      Am I doing it wrong?

      It is preferable to run a full node.

      The torrent is a workaround until "headers first sync" is implemented, at which point, it will be faster to download from the P2P network.

      Today, the torrent makes some client syncs faster, and also lessens the load on the P2P network.  It is more useful for the P2P network to be used for distributing recent information.

      https://s3.amazonaws.com/bitcoinarmory-media/announce.txt seems to contain the link to their bootstrap torrent file. They plan to change it every 2-4 weeks though and have a handful of seedboxes they pay themselves... Also they use a central tracker and set the private bit on their torrent file, so there will be no DHT or PEX for clients who respect this (most do). To me this sounds more like a way to track Armory users and a privacy risk than anything else, I'd advise against seeding the Armory torrent "for fun" or to help them out unless you know what you're getting into.

      Anyways, this could be made MUCH easier for everybody involved if people would actually read up a bit on RSS feeds for torrents! /rant

      I'm not going to seed some random stranger's torrent, sorry.

      If you connect a full node to the bitcoin network you also download data from random strangers. As I understand it the data in this file is subjected to exactly the same checks as data downloaded by the bitcoin client itself. Should the data be misformatted it will be rejected. If some of the end blocks got reorganized the client will sort it out once it connects to the network proper.

      Of course you are right to be paranoid but I don't see the need for this torrent to align with checkpoints in the code itself.

      Post by: Sukrim on July 06, 2014, 05:41:02 PM
      After checkpoints there is little need to get data from a torrent file instead of the network itself, since it is likely a CPU or disk IO bound operation, not network speed.

      Also with this other torrent file, there is no way for me (other than downloading the whole file and decompressing it) to recreate + verify it locally.

      Network speed is an issue, that's why we are using a torrent. There are currently 14620 blocks between the end of this torrent and the end of the blockchain. Bitcoind should download about as fast as torrent does, but sadly it doesn't.

      Bitcoind verifies this data when it imports it, just like when it verifies data it pulls off random network nodes. The only possible attack is a 50%+1, and if an attacker could pull that off they would do it on the main network, or more likely they would just mine half the coins instead.

      EDIT: For clarity

      The verification speed when verifying blocks past the latest checkpoint is far slower than getting the blocks from the network usually.

      The verification speed when verifying blocks past the latest checkpoint is far slower than getting the blocks from the network usually.

      Experimentation being the basis of science I tested your theory. I used a AWS m3.xlarge with a 60GB SSD block device for the bitcoin client. I created a bootstrap.dat for block 305000 and compared the time it takes to update from block 295000 to 305000 via my bootstrap.dat and by pulling blocks from the live network. It turns out you are right.

      Time to update from 295000 to 305000 with a custom bootstrap.dat: 3845 seconds
      Time to update from 295000 to 305000 by connecting to the live network: 3848 seconds

      As a 3 second difference on a 1 hour load is meaningless I can only conclude there is no reason to update this torrent. I'll keep throwing bandwidth at it.

      The verification speed when verifying blocks past the latest checkpoint is far slower than getting the blocks from the network usually.

      Experimentation being the basis of science I tested your theory. I used a AWS m3.xlarge with a 60GB SSD block device for the bitcoin client. I created a bootstrap.dat for block 305000 and compared the time it takes to update from block 295000 to 305000 via my bootstrap.dat and by pulling blocks from the live network. It turns out you are right.

      Time to update from 295000 to 305000 with a custom bootstrap.dat: 3845 seconds
      Time to update from 295000 to 305000 by connecting to the live network: 3848 seconds

      As a 3 second difference on a 1 hour load is meaningless I can only conclude there is no reason to update this torrent. I'll keep throwing bandwidth at it.


      One flaw in your test:  I'm pretty sure when you give the Bitcoin client a bootstrap.dat file it doesn't just "update" but instead rescans the entire blockchain database on your hard drive.  That's why the bootstrap.dat is meant to be used on a fresh install because if you already have a good chunk of the blockchain downloaded you're usually better off just letting the client update from the network.

      Also not everyone has the bandwidth of an extra large AWS instance.  With my slow 3mbps/384kbps DSL line, I may be the exception in that I could possibly rebuild my local database faster than I could download the latest blocks.

      One flaw in your test...

      I didn't go into exact details about how I tested because discussions like this tend to never end. If there was a significant advantage or disadvantage to using the torrent I think I would have seen it.

      Please do treat my results with scepticism and test yourself.

      Looks like update needed :)
      I made a linear block chain up to 309000, 7zip it and put into torrent.
      It is like 12,3GB.
      My home upload is ~500kb/s so it will take some time to move it to better seeds... hopefully one day tops :)

      There isn't a 'they', there is only an 'us'. If you think it should be done then do it. I was going to but my tests showed that using a bootstrap file doesn't load data into bitcoind any faster than pulling the data from the live network for blocks beyond 295000. The recent blocks seem more complicated than earlier ones. Maybe a bigger bootstrap file would still be useful to some people.

      I really think that most users should be using a light client like electrum anyway. Interested companies, organizations, and technical users should be running the full nodes, not every guy who wants to make small purchases.

      I am checking this out now.

      A month ago it took me about a day to download the whole blockchain with the wallet.
      I will see how fast the torrent and validating is.

      At the moment it's very promising, like 25 MB/s download speed.

      Alright. It took 26 minutes to download.
      Now starting the wallet..

      It says it's importing data.... fine...

      10 minutes in... it has imported about 170'000 blocks....

      1 hour later ... 230k blocks.

      1.5 hours later .... importing block 250k.... importing sure takes a lot of time...  :( but we are getting there...

      2 hours, 270k (that's end of november 2013)... at this rate it should take another hour to finish...

      I was wrong... 3 hours, it's at 283k... I give up... I have to get some sleep... lol...

      PS progress bar is at about 40%... but don't think its an accurate estimation of time needed.

      But if it is, then it might take another 3-4 hours to stop.... will see tomorrow...

      it took 7 hours to get here.
      It'll probably finish now in a 1 hour or so...

      Now it switched to synchronizing with network for the remaining blocks that weren't in the torrent.

      You can use this command for increasing syncing speed from your computer not from internet. :)
      Code:
      -dbcache=<n>           Set database cache size in megabytes (4 to 4096, default: 100)

      You can use this command to decrease the connection to number of peers, if it is affecting your internet browsing.
      Code:
      -maxconnections=<n>    Maintain at most <n> connections to peers (default: 125)
      IMO it won't affect in a great way but might affect in a very low speed networks.

      What about other trackers? Open, less politicized,  trackers, that aren't associated with thepiratebay.se? Or maybe differently politicized trackers associated with other organizations? While those 4 trackers are reliable and well defended against DDoS, they are also the ones that are most commonly blocked/censored/filtered by various software nannies.

      Since I was curious about the new torrent, here's some info:

      new bootstrap.dat contains up to block height 313000 (July 8 )

      The new block data (this is using the hexidecimal form) matches my bitcoind's:

      $ ./blockheight -l 295001 < bootstrap-313000.dat | sha256sum
      6cccd54b215799d91b6781b190903fb5673cf6413d2a93c5ebe26223e3b2de21  -
      $ for((i = 295001; i < 313001; i++)); do  ./bitcoin-cli getblock `./bitcoin-cli getblockhash $i` false ; done | sha256sum
      6cccd54b215799d91b6781b190903fb5673cf6413d2a93c5ebe26223e3b2de21  -

      Previous data matches:

      $ dd if=bootstrap-313000.dat bs=335633 count=52206 2>/dev/null | sha1sum
      78a4b41ba7ed823c78cd9ca81a6de393c0ccc226  -
      $ sha1sum bootstrap-295000.dat
      78a4b41ba7ed823c78cd9ca81a6de393c0ccc226  bootstrap-295000.dat


      Can you re-add a http:// based tracker?  The UDP trackers aren't supported by older transmission (2.13 from EPEL).  The exodus.desync.com tracker in the previous torrent seems to be working well.

      Edit: UDP trackers actually do support IPv6, but support varies depending on your torrent software.

      Please post your tracker suggestions.
      I nominate two trackers that are open, differently politicized and seem to work reliably globally.

      http://tracker.humblebundle.com:2710/announce

      http://bttracker.crunchbanglinux.org:6969/announce

      If you are changing trackers in your torrent, please replace remove ccc.de with demonii.com. In my opinion it doesn't make sense to use more than 6 classic trackers in addition to DHT and PEX that are used in a non-private torrent. You should be able to change the torrent without changing infohash, the trackers are in the "announce" section that isn't covered by the hash of the "info" section. There are apps and web sites that will help you do that change, although I don't have links handy.

      From the other trackers that were used in the past: h33t.com domain is disabled by a complex legal issue and won't be back for a while.

      I'm not a torrent&tracker expert either, but have fresh experience troubleshooting these problems for the others.

      Edit:

      The exodus.desync.com tracker in the previous torrent seems to be working well.

      No, please don't. This is an example of dual-stack IPv4+IPv6 tracker that causes problems to many Windows users. Modern Windows versions support IPv6 out-of-the-box via Teredo tunnels and this just causes trouble and confuses the beginning users. The IPv4 side of this tracker is not globally accessible, some big European ISPs are on their block-list.

      Edit2:

      Upon further review of the recent torrent statistics in Windows I'm going to advise against using open.demonii.com. Again the problem is dual stack IPv4+IPv6 with bad accessibility from various places around the globe.

      Edit3:

      Since I've posted this humblebundle.com implemented registration & filtering in their tracker, so it won't work with 3rd party torrents.

      From a security standpoint: Doesn't sharing the Bitcoin blockchain file like this cause the file to become at the mercy of the original uploader's intents? (and thus centralized?)

      For example, if the uploader of this bittorrent blockchain file decides to share an altered/corrupted version of the file, and if everyone uses his version (assuming he has over 50% of people using his version of the file) then his blockchain version will be effectively adopted including all alterations to it?

      Just speculation here as to the potential drawbacks of this method.

      It seems to centralize the blockchain, due to the one individual starting the torrent.

      It is very easy to check, we have at least dozen of block explorers.
      When u use some of this torrents, you just need check for block hash and it is all clear.
      Blockchain can not be corrupted/faked because of power that is need to solve single block. And all blocks after this "crafted" one have to be solved to.

      Chances of corrupting bitcoin client by feeding it a corrupted bootstrap.dat are the same as feeding it corrupted data through the listening port: pretty low, mostly wasting time and bandwidth.

      The only nefarious thing I can think of is to seed it and listen for the fresh leechers. Statistically speaking there's much higher chance than the leecher of this torrent is a Bitcoin beginner and is possibly somewhat impatient. Therefore there are bigger chances that the leeching computer is still not properly configured/secured and attacking it may give a higher chance of finding a successful exploit.

      Note:  For a minority of users, the bootstrap.dat "one huge 20GB file" import method does not work beyond 4GB of data.  This is due to some limitations with large files on some 32-bit operating systems.  It is planned to move away from a single bootstrap.dat file to a directory full of blkNNNNN.dat files that may be imported directly into bitcoind via "-reindex".  The bootstrap.dat file also causes a 2x disk space increase over the "-reindex" method, which occasionally triggers complaints from users on low disk space cloud servers.

      For these reasons, bootstrap.dat import method is being deprecated (at least with regards to this torrent).  Today's torrent update will be the last bootstrap.dat torrent.

      As far as I understood it, bootstrap.dat gets loaded automatically while with "-reindex" people need to know how to add something to a command line. I am not sure if this is not causing more issues for more people than the ones trying to run Bitcoin-Core on some ancient hardware.

      Also Bitcoin-Core could prompt the user after importing from bootstrap.dat to delete the file, to combat the "double space taken" issue. I'd at least like to see both approaches continued until Bitcoin-Core finally is capable of downloading blocks from more than one source, then this whole thing can be discontinued anyways.

      I agree keeping the process automagically performed is better for new users.

      How about include an empty file (flag file) in the torrent which only purpose is to indicate to the bitcoin daemon/wallet run the reindex process (the daemon/wallet would automatically remove this file after the reindex process is done) ?

      Absolutely. Using a torrent at all is a hack and a (small) barrier to entry that should be removed if possible.

      But if using a torrent is the current plan I can throw bandwidth at it.

      There seem to be more downloaders than seeders on the new torrent right now. After changing torrents I'm downloading at 0kB/s and uploading at 1 MB/s.

      If you already have the blockchain you should generate the file using the auxiliary script linearize.py instead of downloading it through the torrent (it is faster than downloading it and doesn't hurt the ones already seeding it, leaving bandwith for the ones who really need to download it).

      Despite of that, it is good to have more seeders indeed.

      Torrent officially updated!  See OP.  New height:  317,000 @ 22.5 GB

      No surprises comparing this file (sha256sum d05062052be4dd6fbaeac5f17598e52f7ad545f9f938acefaf7067ecce1d7b5a) with the blockchain.  I hope posting these verifications is useful to others.

      I'm doing it this way because it's faster to stream data out of bootstrap.dat rather than pulling the data out of bitcoin-cli.  So I can generate the sha256sum from the client once for a given range, and use it to verify that the data hasn't changed.  Future updates just need a checksum out of bitcoin-cli covering the new parts.  If anyone's interested in the blockheight program, I can publish it.

      Blocks 0 through 295000, bootstrap matches blockchain:

      Code:
      $ ./blockheight -e 295000 <bootstrap-317000.dat | sha256sum
      d83ea8602fb5d2ad863afc7fae1b25794bc7da37d2da642e6aca15f2ad19d9e9  -
      $ for((i = 0; i < 295001; i++)); do  ./bitcoin-cli getblock `./bitcoin-cli getblockhash $i` false ; done | sha256sum
      d83ea8602fb5d2ad863afc7fae1b25794bc7da37d2da642e6aca15f2ad19d9e9  -

      Blocks 295001 through 313000, bootstrap matches blockchain:

      Code:
      $ ./blockheight -s 295001 -e 313000 < bootstrap-317000.dat | sha256sum
      6cccd54b215799d91b6781b190903fb5673cf6413d2a93c5ebe26223e3b2de21  -
      $ for((i = 295001; i < 313001; i++)); do  ./bitcoin-cli getblock `./bitcoin-cli getblockhash $i` false ; done | sha256sum

      Blocks 313001 through 317000, bootstrap matches blockchain:

      I agree 100% with this choice, it does not make any sense to have a large file when smaller ones are easier to manage.

      This way, people that already has the first blocks can skip those ones and let their bittorrent client only download the last ones.

      Armory already downloads the blockchain through bittorrent by default, I wish the bitcore core client start doing it as well, until that moment you can count on me seeding this torrent manually for everyone at any time.

      If you're setting up a new full node, it's faster to get the blockchain via torrent (and then let bitcoin core import and validate it) than to let bitcoin core download it by itself. This is because bitcoin core currently downloads from one peer at once, which isn't optimal.

      It took me 3 days with a 100MBit connection with bitcoin-core. As has been said: you sync only with one client, if you are lucky they have a fast connection. With the torrent you will use your line at ~90% (keep 10% for orga/surfing) or even fully*. It went up to  When you are done keep seeding to help others.

      * Edit: just did a test. The torrent runs at ~ 24MBit/s after ~30 seconds. bitcoin-core is never going to achieve that rate.

      22500000 bytes are approx. 21 GiB (1024 bytes = 1 GiB), so if your client displays "21 GB", it is already the new file.

      '7mb' is pretty fast.  I'm going to assume that's 7Mbps and not, hrm, 56Mbps.  I had bonded DSL that was 25Mbps, supposedly being increased up to 60 soon...

      Anyway, I can fully reindex the blockchain in an hour or so on an i7-4770, w/ the blockchain all being stored in RAM.  On a 7Mbps link, it'd probably be faster to download it from a fast node and sync it as it downloads, if you have anything faster than an i7-2600 or so.

      Hello,

      for those of you that have problems downloading from the torrent, I have created a par2 parity volume of the bootstrap.dat file that has 317000 blocks (22566124235 Bytes).

      Bittorrent makes a pretty good job of distributing rarest parts of the file first, but if someone has problems getting the full boostrap.dat file from bittorrent, she can try to reconstruct it from the parity archives I have created.

      I have created enough recovery blocks to help people reconstruct the full bootstrap.dat (of about 22 GB in size) even from the old bootstrap copy from April that cointained about 17GB.

      I encourage you to first download the index bootstrap.dat.par2 and verify how many blocks you need before trying to download the rest of the par2 blocks you need.

      Here you have almost 5GB of recovery blocks with a small block size of 2 MB (exactly the same as in the torrent), which is an extreme test case for any PAR2 implementation: https://mega.co.nz/#F!ixcyQRJB!toDzjgV9XTYAs1WBQ6lTnA (https://mega.co.nz/#F!ixcyQRJB!toDzjgV9XTYAs1WBQ6lTnA)

      You might want to download them though bittorrent as well: http://torcache.net/torrent/6D89F7B4327E2A1EBC7BD3DC269825DF92D660C3.torrent

      P.S: Please be advised than par2 recovery its quite time consuming and this should be only viewed as a last resort in case you cannot download the file through Bittorrent.

      I'm totally new to bitcoin and I just have to get this off my chest now: dealing with that huge database was one of the most nightmarish computer experiences I ever had.

      Why does nobody ever mention that it's not just the slow download that makes getting the database such a pest, but also the IMPORTING of the full database? I first downloaded 17,2 GB successfully through the software, then I got your torrent with the intention of speeding things up. Now I find out that IMPORTING the database is AT LEAST as slow as downloading it.

      My nice old torrent ratio is fucked up now. I will need a new external HDD, if I want to keep that intractable database (I'm one of those that couldn't move it around between partitions because of the size limit mentioned in this thread). And I STILL haven't got the database working. I feel like my computer and my HDDs, running at full speed, have aged by several years over the last days ...and so have I.

      Using bitcoin together with that database seems to be for geeks that have at least one spare computer at home and can use it for installing and importing this intractable database.

      I'll probably give up over the next days, if "importing" the final 2 GB from the database will never stop (it sure looks like it), and probably will stick to using online wallets. This is simply too much for me, my nerves and my computer.

      I wonder, why can't the database be torrented in its original form (the way it appears after it is imported), so it only needs to be verified within perhaps half an hour or so and not "imported" over several days?

      BTW, the download of the torrented database went real fast at full speed (16 MB here), and it's nice to see that there are so many generous contributors (seeders) in the community.

      Because that would require trust. Would you trust strangers on the internet that the data on your copy of the blockchain is legit? Your clients needs to verifiy each block. If you think its such a hassle you can allways use thin/lite clients like electrum or multibit. They offer the security of a local wallet yet dont require you to download the complete blockchain.


      Title: Re: [ANN] Bitcoin blockchain data torrent
      Post by: Kelp! on September 15, 2014, 03:14:13 PM
      I do have MultiBit already (to make it run, I had to install bulky Java again, after I had uninstalled it just a few weeks ago, duh). Electrum didn't run here at all. I sure would have liked to handle it the more professional and securer way, with the database. Maybe I'll go at it slowly, importing a few spare hours every day, though that will make importing the final two gigabytes last for a week probably.

      Regarding the torrent, I always thought, if a torrent file had been tampered with, it would be rejected by trackers. But I trust, if it worked like that, the good people here would have used it that way already long time ago.

      It would have helped, if in the very FIRST POST some of the problems to be encountered with the database would have been mentioned:

      1. For instance, it isn't mentioned that you need a free space of over TWICE the size of the database on a partition to be able to "import" the torrented database. I was moving data around like crazy between partitions and external HDDs, just to be able to accomodate that huge database. And later I had to move around yet more data when I found out that I needed twice the size to "import" the database successfully. I also found out that I couldn't move the database to an external HDD at all because of that file size limit mentioned only later somewhere in this thread.

      2. Also, the fact that the process of only IMPORTING from the torrented database (not just downloading through the client) will take quite a few days (with the computer using up almost all system resources and slowing down other processes) should be mentioned in the FIRST post, so people get an inkling of what's coming towards them. I've gone too far by now (with 19,6 GB successfully imported) to give up at this point. I'll probably carry through to the end, then see how the client behaves during future updates ...and then probably delete the database and stick to MultiBit. ;)

      Plenty of people mention this.

      The "headers-first" feature, hopefully in 0.10, fixes this issue.  With headers-first, the client will import much faster than torrent + import.

      If a couple dozen GB are "huge", you might want to get a new HDD/SSD anyways. Ten times the size of the block chain in storage costs about as much as a BigMac menu at McDonald's... Who the hell uses several partitions on one disk these days anyways?

      Also reindexing takes a few hours at most on my machine, so probably you're running on something that might not really be fit to run a full node in the first place.

      The thing is running full nodes really is for bitcoin geeks. We want as many people running them as possible but the fact is that it's just not the right solution for most casual bitcoin users who just want to use bitcoin rather than run the infrastructure behind it.

      The right solution for you is Electrum, Multibit, or some other light client. They still do the signing on your hardware with private keys only you have access to, so they really are as secure as a full node. I don't know why Electrum doesn't work for you, I thought it was quite reliable on windows.


      Title: Re: [ANN] Bitcoin blockchain data torrent
      Post by: Kelp! on September 26, 2014, 02:40:39 PM
      Electrum doesn't run here because I have only XP with SP1 installed (and I won't update for various reasons). Some software requires at least SP2 to run. Of course, MultiBit requires Java to be installed. So, I'm sticking to MultiBit with Java now.

      I've given up now using Bitcoin Core with its 21 GB (and growing) database because simply starting it with an up-to-date database, it would take about 20 minutes on my computer to "verify" before the program could be used ...and then it would still take quite some time until the newest blocks were downloaded. That's a no-go for me. Considering that I'll perhaps make one bitcoin transaction every few months and I'd then have to wait for hours to download the newest blocks, MultiBit is the right solution for me.

      I'll keep seeding the torrented blockchain for a while and use it to test my new VPN connection (I only started using bitcoin to pay for the VPN service in the first place). I'll also be on the look-out for future improved versions of Bitcoin Core (as hinted at by jgarzik) and test them once in a while. It IS a fascinating project.

      The list for WinXP is long and its the "go to"-system for examples in the metasploit books [1] because its so easy to gain access to. Most exploits however need either an open port or the victim to request it (usually via browser).

      Again, I did not intend to derail this thread with offtopic replies and if you are aware of the risks, go ahead. Its just that most people I encounted that still use WinXP do not use it deliberately but out of lazyness. And yes I am a bit paranoid.

      How much time I need to sync the blockchain from zero using bitcoin-qt and how much with torrent?
      I have a 7mb adsl.

      It took me 3 days with a 100MBit connection with bitcoin-core. As has been said: you sync only with one client, if you are lucky they have a fast connection. With the torrent you will use your line at ~90% (keep 10% for orga/surfing) or even fully*. It went up to  When you are done keep seeding to help others.

      * Edit: just did a test. The torrent runs at ~ 24MBit/s after ~30 seconds. bitcoin-core is never going to achieve that rate.

      I'm in Australia on ADSL2+ (24Mbps max is quoted by companies so I'd think ~10Mbps is true speed as max torrent DL speed I get is ~1150kbps ~= 10/8).
      I am getting 450kBps rate presently, which I'd have to think is ~50x faster than Bitcoin Core.

      There must be a better way than having 1 peer sending the blockchain; the upload bandwidth jammed to a halt for 4-5 days is infeasible at the painful induction crapshoot.

      Best way to resolve the issue? If you've either 1) DLd the torrent once before or 2) waited while BTC Core did its thing for 4-5 days, or 3) like Bitcoin ... seed the torrent!  ;D

      I'd like to post a suggestion for those who are about to download the torrent blockchain and who care about their existing fine torrent ratio in their old torrent client:

      With such a huge download (21GB right now), any sweet torrent ratio will inevitably get borked quickly (depending on how many GB you had uploaded previously). To save your old nice torrent ratio, consider getting a new torrent client (preferably a "portable" one) and use it only for downloading the blockchain. When you decide to seed it (either part of it, or 100% or more of it), you can load it in your old torrent client, and even improve your old ratio quite substantially by seeding that huge database.

      I wish I had done it like that, before I fucked up my cute old torrent ratio with this blockchain torrent. ;-)

      Indeed, so in order to avoid a "bad ratio" just share the blockchain data torrent until you uploaded at least as much as you downloaded.

      Not necessarily. If you had a ratio of e.g. 2.0, you'd have to upload the file twice to get your old ratio back. For people with an average DSL connection, with typically fast download speeds but low upload speeds, that's almost impossible to achieve, especially when they prefer to go about other torrents. So, using a different torrent client exclusively for the blockchain torrent, is a simple way to keep your old ratio.

      Esp. if you use torrents on a regular basis you should just keep this one running for a few months. Everyone seeding is increasing its speed for those downloading it. If you care enough about other torrents to get a 2:1 ratio, why not about this one?

      Like I said, with some DSL connections it's technically almost impossible to achieve (except you let your computer run 24/7 for some time). I'll try to reseed about half of the blockchain, I don't think I have the time and patience to reseed it entirely. I also need to delete the blockchain torrent eventually, to have more free space on my HDD for other torrents again. Such an ENORMOUS single file does bring about some problems on some set ups. ;-)

      I was updating from the 16gig bootstrap to the current (21gig) torrent and noticed they don't go side by side initially (ie. the 21 gig one doesn't start off from where the 16gig one stopped). I deleted both torrents (not the actual bootstrap file) and loaded the 21 gig torrent by itself, it (uTorrent that is) started checking the file as I would expect, but then started downloading from 0%. I expected it would start downloading right around 70% or so. Is this expectation wrong? Or did I do it wrong?

      TLDR; How do I update the torrent to a more recent version without downloading from scratch?

      I am running bitcoin-0.9.2-linux on Debian.  I got a copy of linearize from github and ran it using Python 2.7.3. I had no problem creating hashlist.txt, but when I ran linearize-data.py  I got errors.   There were other skipped blocks, but the end was as follows:

      Quote
      Wrote 239000 blocks
      Skipping unknown block 000000000000007dae319c0420d12bf47f14ed63a994d2402b9bb9a69d0b732d

      Out of order block.

      I figured that my block data was somehow corrupted, so I ran bitcoin-qt with checkblocks=0 and checklevel=3. Then I re-ran linearize with the same result.  Then I ran bitcoin-qt --reindex and spent a day  doing a complete reindex.   I then reran linearize and got the same error. This concerns me, because if my blocks on disk had somehow gotten corrupted then bitcoin-qt should have found the corruption.

      Does anyone have an idea what may be wrong?

      Follow-up edit.  I cleared out all of the files in .bitcoin and downloaded the block chain from another node on my network.  This took about 18 hours. Then I ran linearize and produced a good bootstrap.dat file and it is presently seeding.

      The only thing that really matters is that anyone who wants the data should be able to get hold of it as fast as possible. The more bandwidth we have seeding the better but if anyone really can't seed they should not feel bad about it. It's not an obligation.

      I've been seeding the new torrent for 2 months now on a well connected server and have a seed ratio of 548. That's about 12 TB uploaded by one server in 2 months. I'm wondering if this is all due to people setting up full nodes, or if something else is happening here.

      If you are a long term seeder are you getting similar results?

      This exactly, armory loves using this torrent. I've been seeding it for quite a while now. I tried out the download speed yesterday from this torrent and got around 25MB/s (around the max of the connection I'm using at home). I'm sure it would be even faster on my business connection.

      Either way, keep seeding and everybody thanks for providing this service.

      +1 from the last time that i have rebuilded the blockchain (october 2014).
      bitcoin core is heavy duty corrupted by orphan block (for the new arrival members) ... and very high restriction from the client to upload blocks to others.

      If anyone wants to setup seeders the cheapest way I found was on a AMD Athlon 64 5600+ X2 at https://robot.your-server.de/order/market . EUR 25 a month for a dedicated machine with serious bandwidth. Setting up transmission-cli under screen isn't difficult.

      How often will this torrent be updated?

      Assuming this project is deemed useful and worth continuing... the torrent will be updated once every few months, when the checkpoints are updated in the reference client source code (https://github.com/bitcoin/bitcoin/).


      Why not update the torrent more often?

      A torrent works best when it is a large, static dataset that changes infrequently.  That maximizes the ability to seed the data, enabling even part-timer seeders to contribute meaningfully.  Less frequent changes also minimizes the risk that a malicious torrent will appear, with a long, malicious side chain.  The current policy only updates the torrent after blocks are buried many thousands deep in the chain.

      Note, this will not launch a GUI, use bitcoind getinfo so see the status.

      Well, that was a nice experience.. The database corrupted every single try and I couldn't find what did it..
      So I compiled bitcoind from source and imported bootstrap.dat
      Then finally I went on to connect again to the IP's mentioned before, only to discover that.. I was blocked :D

      Thanks guys..

      Hi, is anyone got a FRESH & CLEAN bootstrap.dat file around ?

      Read the OP and download the torrent.


      I came as far as block 317000. That's more that 13 weeks old tells bitcoin-qt..
      Then I got stuck. I have 12 active connections to the network.
      Is there a regularly, like every 24 hours, maintained version of bootstrap.dat out there?

      So.. I am pretty sure I can take this upon me. Automate it and let it rip.
      The only problem I see is the huge bandwidth capacity needed.

      Answers or suggestions?



      Please take the time to read OP. :)

      Why not update the torrent more often?

      A torrent works best when it is a large, static dataset that changes infrequently.  That maximizes the ability to seed the data, enabling even part-timer seeders to contribute meaningfully.  Less frequent changes also minimizes the risk that a malicious torrent will appear, with a long, malicious side chain.  The current policy only updates the torrent after blocks are buried many thousands deep in the chain.

         ~~MZ~~

      Yes, now I read the whole OP this makes sense.

      The sole reason I appeared here was that I forgot.. one time only.. to backup the block chain database before re-installing a new OS on my computer. I got the grandfather instead of the father in the backup protocol.

      So.. Torrent'ing a bootstrap database, waiting for clues from the local super-heroes.. Because hey.. I just want to pay my insurance on Monday..

      Then.. The realization that many 'contributors' just say "f*ck you, man.." in a newbie's face when he seems to be down and struggling..

      I've seen this behavior before, and at the time I was disgusted by the apparent change. No one seemed to bother to read Virginia Shea anymore and just went on to become rampant egomaniacs.

      Yeah, I know.. This is frustration with the proceedings of a once promising protocol. But right now it seems you are in the tub with that frog.

      A question that reeds to be answered by each and every local bitcoin super-hero: Do you want a worldwide payment protocol, or just goof around for personal glory for some time. Of course there is some momentum still; you've got your new arrivals, and hey.. conferences where you can pat each other on shoulders how ultra-famous that guy is. That actually is my clue that you fail to see the significance of what you are holding in your hands right this minute.
      Later there will be the names, the guys with beards somewhere out there, telling how they had it in their own hands but lost it; fumbled, dropped the ball, and lost the game. So I smile, knowing that some of you will see, and many others will remain as blind as they are..

      Now I really have that insurance to pay. And you're not helping, Eternal September people..

      Packing up..

      I've compiled bitcoind and bitcoin-qt from source on Ubuntu 14.04. I mostly do that, but I was lazy this time so I got the canned version. I should've known better. Then I downloaded bootstrap.dat via Torrent and cleaned my system as to avoid any circumstance that could make things go FUBAR, and ran bitcoind. Nice, it worked: bitcoind was loading blocks from bootstrap.dat, and it seemed to work like a charm. No more corruption of the database like with the canned bitcoind. Good. When bitcoind finished loading from bootstrap.dat on block 31700, I stopped bitcoind. Then I ran bitcoin-qt . To read..: "No block source available. 1 year and 32 weeks behind." "19 active connections to the Bitcoin network," and "Catching up... Processed 232045 blocks of transaction history. ... " I know that my node seemed to be misbehaving because I had to reload the same blocks after every time the canned bitcoind seemed to corrupt the blockchain database. I have never ever experienced this with a self-compiled version of either bitcoind, or bitcoin-qt. Last night I pulled my blocks from famous 173.236.158.177, the blockchain database crashed a few times, and so I'm given no quarters anymore.

      Can you see a newbie struggling with this? He or she doesn't want to be a programmer or systems expert, he or she just want to adopt this cool new fad.. Yeah, it shot up to $1,000 - hello.. geek millionaires - from nothing, and then crashed to like $275 - hello.. people who lost an arm and a leg - something, but hey people seem to think it's viable. Well, this single experience tells me that it is not. This is not a serious global payment system, decentralized or not. This is hobby stuff. And while fiat value - hey.. they CPU mined bitcoin - for some is still good, this is going nowhere really fast. I don't mean that bitcoin will disappear, because let's face it there is a lot of real money put in.. But like this? Like this one experience I am having now, after all these years? Just going it from the seat of my pants one time? Dudes, you are delusional..

      Ok.. I will say it. This actually IRL screwed me over. Ok? There, now you can gloat. Another one bites the dust never to come back again. Happy now? Good.

      You don't need to run a full node or even the reference implementation if you want to use Bitcoin, alternatively you can just wait for 0.10 to come out where bootstrapping should work much faster.

I know what I can do, and I also know what can't be done in my situation now. Yeah, I have not been following devs for years, and yeah, I just took the new source, read the change log, and went on with business. While you were real busy creating your local super-hero status. You know nothing about who I am or how early I adopted Bitcoin. You know nothing about my systems knowledge. Nor about my knowledge of Bitcoin platforms and portability. You don't know if I had a time-window closing. The only thing you know is that I use bitcoind on Ubuntu 14.04 now. And I needed (!) to do it this way. You have not been of any help super-hero. You just did some lip-gymnastics here.

      Hm.. This is the real newbie answer. Biased because of entrance time, and board status..
      I mine Bitcoins yes, for years now. Yes, I CPU mined them also. No, I did not buy a pizza back then.
      But whatever amount, there was very little converted to fiat. So I ain't no fat cat like some, right?
      And yeah, some of my systems run Linux, some don't.
      How I stepped in? Well, I didn't expect a closed community like some of the newsgroups, and I certainly did not expect a post score based status thing. Some seem to need that. Like with reference codes in their .sig.. I didn't see that either.

      So I simply asked stuff I didn't know, right?

      You are right. I just cracked up because I saw stuff getting lost. Sorry 'bout the drama.

      Problem is: after downloading and importing bootstrap.dat and then conncting to the fast nodes, my database crashed a few times because I failed to see the problem was the canned version of bitcoind I used. After I compiled bitcoind and bitcoin-qt from source myself the problem seemed to be over. But now I am stuck again because the fast nodes seemed to have locked out my IP for pulling too much data, or because of a "misbehaving" node status because I pulled the same blocks a few times. I don't know. The only thing I do know is that I am stuck again on a frustratingly slow bitcoin network. Then of course I thought that perhaps "misbehaving" node IP's were propagated over the network leaving my IP address essentially stranded for ever. Like I said, I don't know. But blocks are not loading.

      Perhaps you shouldn't be running a bitcoin node or any kind of large database software on your computer.  I suggest you switch to a light weight client such as Electrum.  There are ways to get your bitcoins into a new wallet based on a light weight client that won't require synchronizing the block chain.

      Is in the same folder as your wallet.dat?

      What OS?

      At least on Windows closing the application might only minimize it to the tray...

      I'd recommend just waiting a few days until 0.10. is released instead of trying to make the import from the torrent working - header-first syncing is so much faster and easier than using this torrent anyways. If it is really urgent, you can already try out the release candidate, it doesn't seem to be very buggy.

      Try adding a node manually with:

      addnode 213.165.91.169 add

      this should help you find other nodes. Full disclosure, this is my node and its not yet updated to 0.10.0rc1

      Thanks for sharing this Bitcoin blockchain data torrent with the community. Very useful in case someone is using the Bitcoin Core for the first time thanks to this feature:

      If the file "bootstrap.dat" is found in the bitcoin data directory, it will validate and import all blockchain data found in that file.  The following torrent presents a bootstrap.dat file for that feature.

      Seeding, too.  :P

      it must be a self defeating process to keep beating myself up like this! LOL!!

      At 88% almost 89 complete I'd hate to trash it all.
      any way to get through this without it taking a month os nights running?

      The torrent of blockchain file is available on Bitcoin.org under the download links of Bitcoin Core and here is => https://bitcoin.org/bin/blockchain/bootstrap.dat.torrent  , I downloaded it and it finished in 1 day 8 hours with a speed of ~200k/s (my max speed)
      One it's finished put it in Bitcoin folder on the AppData and launch your Bitcoin Core wallet and you are ready to go

      You cannot combine two torrents , no .
      I'am not sure about the blockchain that you are downloading , you may wanna finish downloading it then try what I said above if didn't work try to download from the link that I gave you , it's what I'am using and it's working fine without any issues .

      Well Thank you for the advise and assistance,
      The Torrent I was working from finally did finish up.
      By all accounts it's apparently kept up to date.

      after complete, I copied the downladed 21G file into the App Data file as instructed
      (windows), then restarted Bitcoin core.

      Core is "stuck".
      It hangs at 35 weeks "Syncing". When I peek at the Debug log- it repeats
      Data already processed.

      this is sort of a hang? I cant get it to run through the blocks any quicker... Ive tried close, restart,
      same.
      Should I snap a shot of the debug log or does anyone know a work around?
      Any assistance greatly appreciated...Ive been working daily on this since Jan. 14.

      Are you sure about that mate , Have you waited enough because It was Importing blocks from torrent file then when It check & see that there is some missing files (not updated file) , It start Synchrozining with the network , so basically Importing Blocks is a lot faster then Synchronizing with the network and depends on your internet speed . Simply try to wait some time and see if anything changes .
      If the problem consists to happen, simply take a backup of the 21 GB file , Unistall Bitcoin Core (and remove all AppData Files) then Reinstall it once again and put the Bootstrap.dat on the AppData directory and launch. It should work ... I got it stuck last time too and after doing this it worked fine ;D

      Also it might very well be that you already synced with the blockchain beyond what the torrent contains (I'm not so sure what you mean by the "I already have 89% done") and just slowed down your internet connection by downloading both more recent blocks via bitcoin-core AND the initial set of older blocks via BitTorrent.

      As long as you are connected to the Bitcoin network, just let your client sync and it will eventually catch up. By the way, initial sync is very often CPU bound, so if you have an old machine or are doing heavy computations on the side, you'll also often be limited by that, importing blocks "slowly" is maybe the fastest your PC can handle.

      Can I install .10 on top my current last version installation or I need to have a fresh install and download the damn blockchain again? I HOPE NOT.

      Yes.

      If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

      Release 0.10.0 makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with older versions of Bitcoin Core or other software:

      • Blocks will be stored on disk out of order (in the order they are received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
      • The block index database will now hold headers for which no block is stored on disk, which earlier versions won’t support.

      Bitcoin Core now uses ‘headers-first synchronization’. This means that we first ask peers for block headers (a total of 27 megabytes, as of December 2014) and validate those. In a second stage, when the headers have been discovered, we download the blocks. However, as we already know about the whole chain in advance, the blocks can be downloaded in parallel from all available peers.

      In practice, this means a much faster and more robust synchronization. On recent hardware with a decent network link, it can be as little as 3 hours for an initial full synchronization. You may notice a slower progress in the very first few minutes, when headers are still being fetched and verified, but it should gain speed afterwards.

      Maybe that your blocks will be more in order? Just getting 0.10.0 should be enough though, it is faster than loading the torrent and if you want to transfer blocks via USB stick, you don't need the torrent for that anyways.

      AFIK when chain is loaded and UTXO database is created and updated every block, daemon is not looking to old data from chain, so order doesn't matter much.
      Only when RPC getblock happen or another node ask about old data.

      Actually this is not correct. I don't know why nobody replied to the post. Version 0.10.0 did help a lot in increasing the speed, but downloading the whole blockchain is still faster via torrent. Pretty much anything is faster using torrents if there are enough seeders especially if you have a very high speed.
      Syncing from the begging still takes quite some time; pruning is needed.

      Update: Shorena you make a valid point. There is no need for me to make further unnecessary posts here.

      Under the assumption that you do not have horrible peers when connected, using the torrent slows you down. The torrent is just a data download and the data has to be verified. With 0.10. you can download from several sources at once and should be able to max our your connection same as with a torrent, but the machine can verify the blocks at the same time. With the torrent you would have to download first and verify later. Thus its typically faster to use the client. As with everything it depends on your specific situation and environment if this is true or not obviously.

      You dont need bitcoin core to mine with a pool. Depending on the hardware you use mining is probably not profitable for you.
      See this section on profitability -> https://bitcointalk.org/index.php?board=81.0
      Different mining software can be found here -> https://bitcointalk.org/index.php?board=42.0
      If you need help regarding mining this would be the section -> https://bitcointalk.org/index.php?board=40.0
      And finally pools are discussed here -> https://bitcointalk.org/index.php?board=41.0

      You will certainly need a wallet sooner or later, but bitcoin core might not be the wallet for you. There are many different wallets and many of them do not require a full copy of the blockchain. -> https://bitcoin.org/en/choose-your-wallet

      If your index corrupts it just needs to be rebuilt, there is no need to download anything. Also 0.10.0 and newer will download while syncing (which is the limiting part on most machines out there). If you speed up the download step, you don't measure the whole time it takes to get up to sync...

      The torrent shouldn't affect reindexing. You already have all of the blocks downloaded, so the torrent is useless for you. The reindex can only be sped up with either code modifications or getting better hardware.

      Also, the torrent is already obsolete as it is both outdated and in v0.10+ headers first synchronization makes Bitcoin Core Download (but not index) the blockchain faster.

      It is not.
      You have grab torrent, copy it to proper directory, wait for reindex.
      Not using torrent you just need to run Core and wait for download and index.
      Because of parallel and non-linear downloading of chain from peers, at start it seems to be slow.
      Anyway, not having SSD still need days to do 1st sync.

      With new versions, the torrent is ABSOLUTELY NOT FASTER. It is faster and easier to allow Bitcoin Core to sync normally, no need to download a massive file, and the sync is faster due to headers-first synchronization.

      Sorry, but I can not confirm this; at least not if you have access to a very fast internet connection.

       ;D I've just downloaded the latest block chain (bootstrap.dat: 2015-12-10) from Flo's Press 4u: https://flo.sh/bitcoin-qt-bootstrap-dat/ (https://flo.sh/bitcoin-qt-bootstrap-dat/)
      uncompressed the zipfile to my ~/.bitcoin application directory and restartet a brand new Bitcoin-Qt v0.11.2.

      Bitcoin-Qt imported the bootstrap file within minutes. So I'm ready to go (download and unpacking of the bootstrap zip file included) within less than two hours using recent equipment!  8)

      Just starting the plain Bitcoin-Qt client would have taken many hours if not days to complete the same task :P

      Nevertheless downloading a bootstrap file may be counterproductive using a slow internet access technology.

      ;D I've just downloaded the latest block chain (bootstrap.dat: 2015-12-10) from Flo's Press 4u: https://flo.sh/bitcoin-qt-bootstrap-dat/ (https://flo.sh/bitcoin-qt-bootstrap-dat/)
      uncompressed the zipfile to my ~/.bitcoin application directory and restartet a brand new Bitcoin-Qt v0.11.2.

      Bitcoin-Qt imported the bootstrap file within minutes. So I'm ready to go (download and unpacking of the bootstrap zip file included) within less than two hours using recent equipment!  8)

      Just starting the plain Bitcoin-Qt client would have taken many hours if not days to complete the same task :P

      Nevertheless downloading a bootstrap file may be counterproductive using a slow internet access technology.

      That is not the actual official bootstrap.dat. That is the file produced by a third party and has also been compressed from 50+ Gb to around 35+. The smaller size makes it faster to download (duh). I was referring to the official bootstrap.dat which is now obsolete and is still the full size of the blockchain, not compressed.

      It's a standard zip compressed bootstrap.dat (https://flo.sh/bitcoin-qt-bootstrap-dat/) file, combining all blk*.dat files out of the blocks directory.

      Maybe we should discuss adding a zip level compression (or better suitable) algorithm to the Bitcoin-Qt client to reduce the amout of data needed to be transferred to update the block chain.

      Bottlenecks where? Bitcoin nodes download at full ISP speed as well. It doesn't have the additional bottleneck of having to verify all of the blocks after the download. The node will verify the blocks as they are downloaded, not after they have all been downloaded.

It's also nice to have a single file that i can use whenever i need to quickly bootstrap my client.

      I've just set up a fresh full node using 0.11.2 Core client. Syncing the whole blockchain took 4 days. What is interesting, downloading blocks was not a bottleneck. My 20 Mbit/s connection was never fully utilized. What is slow, is population of the database and probably building base of UTXO. I admit that my setup is rather slow: Core2Duo @ 2.4 GHz and external 1 TB HDD (5400 rpm) on USB 2.0. With this setup HDD seems to be the major bottleneck.

      Import the torrent file into that and then update the software to the latest version.

      Would this work better to syncronise to the network, as I have been told that, when switching between versions, the initial blockchain import is not required? Have I got this correct?

      I think t's best that you download the entire blockchain from scratch no matter what, it's worth investing into the extra time for the extra security. Why do you want to install an old version anyway tho?

      It will take much less time and there is no need to re syncronise the blockchain after this is done with the newer version. It will just runn the veryify blocks process.

      With new versions, the torrent is ABSOLUTELY NOT FASTER. It is faster and easier to allow Bitcoin Core to sync normally, no need to download a massive file, and the sync is faster due to headers-first synchronization.


      Let me share my story.

      I have a small NAS, used also as set-top box to my TV. It runs debian. I decided to give the Bitcoin a try, and set up a node - I have plenty of space there, and this box is used sporadically.

      I downloaded fresh version of Bitcoin (at that moment, 0.11.02), and started downloading the blocks normally. I have a decent speed to the internet.

      I took over a month to download the whole blockchain, and I have logs to prove it. I have monitored its progress - bitcoind used just a small bandwith, but always 100% of my CPU, on the NAS. It os not very powerful CPU, I admit, so I wasn't surprised. It was the computation that caused the blockchain to load slowly.

      When it finished, and started running "normally", the CPU consumption was about 20-40%. It was quite expected. But I decided to give the torrent a try, just for sake of comparison.

      The torrent I took from the above linked thread. The torrent downloaded on the same box, with the same CPU and network,  in about 7 hours. Then, I needed to download missing blocks - it took about 36 hours. In total - 42 hours.

      In both cases the blockchain is about 62 GB big. The MD5 of the files are different, though.

      Now my points:

       - there are computers with slower CPU. Keep this in mind. My case was extreme, but it's just proof, that CPU is also very important during downloading the blockchain, and people having problems with slow downloads perhaps have probelem with CPU, not network.
       - precomputation is just reasonable. Why everyone should compute the same blocks every time they start a new node?
       - if you prepare "certified" blockchain (can be GPG signed, etc.), you will show the people that you CARE about them, and about their time, and freedom of choice of downloading method. This is important for people that are hesitating about running a bitcoin daemon.

      Thanks for reading.

      January 11th 2016 blockchain full download
      ~~~~~~~~~~~~~~~~~~~~~~~~~
      Here I report my most recent performance as it will help others to decide what hardware is sufficient.  
      It was to a VBOX virtual machine in linux on a quad-core i5 throttled to <75% x 4cpu cores.
      Download of the whole blockchain from block 1 to present took about 2 days.  /.bitcoin/ is now about 65GB
      2009 to 2013 parts of the blockchain maxed out the 4x cpu usage.
      After that it slowed down, with 4x cpu usage decreased from about 95% x 4 x 2.3 GHz to (4 x 2.3 GHz about 40% of the time).
      I suspect that the most recent 40GB of the blockchain were synching at a rate limited by my HDD rw speed and seek time, so a faster HDD such as a SSD would be the best available speedup, and might get a full blockchain download down to less than 40 hours.  What have others been seeing?

      I don't think that the original bootstrap.dat is much help now as it only does the "easy" third at the start of the blockchain.

      Yes, the overal speed depends on more than just bandwith.

      - precomputation is just reasonable. Why everyone should compute the same blocks every time they start a new node?

      You either used the "bootstrap.dat" in which case you did not safe any computation time, but rather wasted it by seperating download and verification. From the times you states and "precomputation" however I assume you downloaded a preverified blockchain. This is naturally faster, because you dont do all the work. Thus the comparisson is invalid and you need to trust the other party to not have messed with the blockchain.

      You should verifiy the blocks to avoid this exact problem, trusting someone else. The same way you verify the binaries you download or the signed message you receive.

      - if you prepare "certified" blockchain (can be GPG signed, etc.), you will show the people that you CARE about them, and about their time, and freedom of choice of downloading method. This is important for people that are hesitating about running a bitcoin daemon.

      Thanks for reading.

      Which will require you to trust that person and their ability to secure their PGP key. People are not hesitating to run a full node because of the initial time it takes, but because of the constant time it needs to download and verify data. If it would just be 1-3 days (relativly modern desktop/laptop computer) it would not be an issue.

      That's exactly my point - why would I have needed trust someone else, if I had had the opportunity to download pre-verified blockchain as a package, certified by bitcoin.org ? That's just giving the people another way of getting bitcoin node up and running very fast. Precomputing means not only wasted CPU cycles, but also HDD operations, as there was reported that every block requires much more HDD transfer, than just size of the blocks.

      There still will be option to run bitcoind from scratch, for any people that just want to "fire and forget", and that is good.

      Post by: whizz94 on January 17, 2016, 09:40:36 AM
      Definitely no for BTC.

      For the whole month of August I had my quad-core B2 raspberry pi trying to download and sort the whole blockchain to its compiled-from-src bitcoin-qt.  It crashed and required bitcoin-qt -reindex several times and in one month of usage never completed the necessary first -reindex task.  It seemed to get slower and slower as the number of weeks remaining decreased to 50 wk, (synched up to mid-2014) and eventually I started using a spare i5 instead, which overtook the rPi in a couple of days.

      In 2016, I have this rPi being an unobtanium-qt node and a couple of other altcoins too.  They are all a bit underused but seem to have faster confirmation times than BTC and be better suited to (if my neighbours were to pay pocket money for mowing the lawn).  I've just tested an unobtanium electrum-uno lightweight wallet which showed "pending" within the same minute as sending a test transaction from the rPi node via the international UNO blockchain to .. the other PC across my desk. 

      If you are serious about power saving then try something like this by all means, but read around to avoid the various scamcoins and proceeds-of-crime coins which are around.

      Please don't close it. Lots of people with unreliable hardware or network problems are still better off downloading separately from initializing the blockchain storage.

      There are many people with non-flat-rate network hookups or with over-the-radio hookups with shared IPv4 addresses that continue to download the torrents from this thread.

      So what? It is and it forever will be a proper subset of the valid data. This torrent is sufficient to reliably trigger bugs in certain popular/cheap flash storage devices. This alone would make it an useful test case for at least decade, maybe more.

      Also, there are (non-English language) papers that use this torrent for performance comparison of various file systems, alternate storage engines and file/partition layouts.

      It is NOT good way to bootstrap node.
      This is just your personal limitation that you can't or won't understand why separating over-the-WAN download from over-the-LAN initialization is and will be useful troubleshooting and testing tool.

      Also, there are (non-English language) papers that use this torrent for performance comparison of various file systems, alternate storage engines and file/partition layouts.
      Got some links? Also the ad-hominem is not really useful, using the data in this torrent is objectively a really bad way to bootstrap your node in case you just want to get it up and running as fast as possible.

      there are some people who has contrary belief to what is better:
      download the entire boostrap.dat
      OR
      start a node and download the data from other nodes.

      I wonder if someone has the technical knowledge to clarify this

      Until about version 0.10.0 it was much faster to download the bootstrap.dat file.
      Since that release of version 0.10.0 it was faster just to leave a node to download it unless you have a dial-up modem or limited internet access (but it'd have to be less than about 100kbps to slow if down by an unreasonable amount that makes downloading impossible). If you have an internet speed that sliw however, if wouldn't be productive to run a node anyway and you may as well use a light wallet instead.

      Torrents make heavy use of checksumming/hashing, so while in the block chain you need to have all previous headers to verify the current one, in a torrent file you just need any chunk of data. Other comments were saying that a feature was being implemented so that all of the headers would be downloaded first and the actual blocks could then be downloaded in any order. I'm guessing the client pretty much has to download the headers serially still in order for the distributed nature to continue working. Serial downloading of the blockchain probably makes it easier for the client to check that nobody is bullshitting them with an incorrect version of the blockchain.
