Does anyone require this link anymore? We currently have duplicates, probably not necessary.

Yours has a distinction of actually working. The one posted lkloon123 don't seem to work. They seem to hang on: Preparing download: zipping 1 file: progress circle gets stuck below 25%. In a dedicated Google Drive download utility they show as "files offline".

So maybe keep your until somebody confirms successful use of the other links?

Edit: Further research shows that barto123 posted hyperlink to a file, but lkloon123 posted link to a directory of subdirectories (named with a date) that contain the actual RAR files. Google Drive must have different special cases for different browsers. I managed to start download of lkloon123's post by starting it in "Google Internet Explorer Chrome", pausing the download and then copy-pasting the end-file link to a browser not approved by Google.

Pain in the neck, but it could be made to work. I'll update one the RAR download finishes and passes verification in unrar.

Apologies for that Dropbox link, they only allow a small of downloads per day. Trying Google drive now. *Bitcoin Blockchain Updated 10 Jun 17*

Trying to help Bitcoin & get more nodes running to activate Segwit. These transaction fees are a killer!

If you run one of these clients https://uasf.bitcoinreminder.com/ you will start showing support for BIP148 UASF - before Activation on 1 Aug 17. The more people that run it the better the chance we have of getting Segwit. The power is in the users hands!

A small donation would be appreciated for cost of the cloud storage, however not necessary.

Please let me know how you go with that link.

I will leave this up as there's most likely going to be a need for 2 links with all the UASF traffic. Bitcoin is growing really fast.

Yeah, I can confirm it "works", i.e. downloads in full and restores correctly.

The question is "how much effort is required to use it on a clean computer, especially Windows?" When somebody doesn't already have Google Chrome and payware RAR utility this isn't so easy.

Depending on the country the attempt to use of directory-level Google Drive link in Microsoft Internet Explorer one ends up with either a hang (described above) or a prompt to upgrade browser.

I don't know if payware RAR utility is smarter, but the freeware unrar restores those directories in a heavily fragmented state. It doesn't make sense for anyone to pay for full RAR license (or lookup the ever-popular cracks) when all that's required is a one-time uncompressing. With heavily fragmented store Bitcoin Core client works much slower then when it would do the download itself.

Yeah, but it makes everything go much faster, especially for users of the ISPs which don't have fully routable IP addresses but have to use to use CG-NAT-ed shared IP addresses. Google Drive doesn't seem to do per-IP throttling unlike e.g. Mega.nz .

Now, Blockchain requie over 120G, it too big for my PC,
other way to used Bitcore?

Usually you are not required to store the complete blockchain on your PC.
Did you consider to use pruning to reduce your storage requirements?

It's about adding a line "prune=[allowed blockchain storage in MB]" to your bitcoin.conf configuration file.
A value around 4488 [MB] which is currently about a month of backlog may be useful.

Yes, the recommended way is to sync the client alone.

But nevertheless an up-to-date bootstrap.dat file is useful for some usage scenarious like:

• rolling out multiple installations
• speeding up the initial sync (because the bootstrap.dat is already serialized)

Die Idee ist gut aber an der Umsetzung scheitert es anscheinend. Hab "gespendet" damit ich den Downloadlink bekomme. (Es ist keine Spende sondern eine Bezahlung für "deine" Dienstleistung). Siehe da ich lade mit maximal 2,8mb/s runter(schwankt immer zwischen 1,2mb/s-2,8mb/s. Das ist ja wohl eine Frechheit. Geld verlangen für den download und dann nicht mal eine richtige Geschwindigkeit bereitstellen. Wahnsinn. Kann nur jedem davon abraten.

Hab übrigens eine 400.000er Leitung -> ziehe immer mit mindestens 55mb/s von richtigen Anbietern.

The Idea is good but the downloadserver is horrible. I download the Bootstrap.dat with 2,8mb/s. My Internet download is normally 55mb/s. Really bad service which you have to pay for.

[lungbubble]

Okay, so people keep saying its "better" to download through the wallet program than to download a bootstrap. 

Been syncing for under an hour, wallet claims it will take 7 weeks to fully sync from a clean install. 

How is that faster than under a day that would be required to download a 50-100gb bootstrap?

Some claim re-indexing is not required with the newer clients as well so that would suggest to eliminate that. 

Even with those things being the case, why is the download so slow?!

With the bootstrap you still have to validate the data. It's not just "the people" who say it's faster just syncing normally, it's the devs and the changelogs...

[Mad7Scientist]

My assumpton is that they're considering that you will reindex (./bitcoin-qt -dbcache=600 -reindex) after you download it from somebody. Of course if you don't reindex then there is no way that downloading with the client could be faster provided that the source that you're downloading from isn't limiting its upload speed.

edit: I believe that bootstrap.dat requires indexing no matter what, so downloading and indexing would always be slower than downloading and indexing at the same time. What I was talking about is actually getting a complete database (blocks and chainstate directories) from somebody.

edit2: If you have a mechanical hard drive, downloading the blockchain requires 2GB of cache memory in addition to memory for the OS and the bitcoin program. In other words you need 4GB and even with that it'll slow down getting in to 2016 data. Also, if you don't have ECC RAM then as single bit error will invalidate the entire index due to something like checksum error - database corrupted or Mekcle Root mismatch and you'll have to start over with the -reindex flag.

Free blockchain download to people in Illinois and bordering States, but please do me a favor. This is an older one that's at block 474777 from June 8th. Also it was created using bitcoin-core 0.12.1. Newer versions should be able to use it and auto update the format but I'm not sure about the newest versoins. This blockchain is already indexed and it was created by myself. You can check my trust with the web of trust used on the IRC channel. I have a high rating. If you're not close to Illinois I'll disconnect you. No, I'm not being charged extra to send to a long distance location, I'm just enforcing my own personal Internet agenda. I'll take the link away once one or two people start downloading it.

If you want to pay me $3 I'll let you download it even if you're not by Illinois. I will also accept 0.0005 Bitcoins, 0.03 Litecoins, or 3 Primecoins.

The favor: When you download this could you tell me if it works on your system and could you check error.log in your Bitcoin configuration/data directory (where wallet.dat is) and tell me if it encountered any errors when you reindex it, if you do chose to reindex it.

Here is the link to the file. It is a 100GB rar archive with a recovery record in case a bit gets corrupted. It also includes peers.dat. I thought that that might help bootstrapping go a little faster some day in the future. SHA1: b4d34735dac777202b681ef021ed38bfd6bc1f02

http://[URL hostname hidden - please PM me for this URL or use the Gnutella download method]/public/blockchains/bitcoin-core_0.12.1_indexed_blockchain_block474777_and_peers.dat_2017-7-8.rar

Once you download it then unpack it in your bitcoin data directory. Make sure to preserve the directory structure in the unrar program or the Windows GUI version. Delete the blocks and chainstate directories first to not have abandoned files around.
In Linux at the command line it would be something like this:
$ cd ~/.bitcoin
$ rm -r chainstate/ blocks/
$ sha1sum bitcoin-core_0.12.1_indexed_blockchain_block474777_and_peers.dat_2017-7-8.rar
# The result should be b4d34735dac777202b681ef021ed38bfd6bc1f02 . If it isn't, then you have a bad download. Try to do a recovery on the rar archive. It will create a copy that's corrected to the correct sha1 hash.
$ unrar x r bitcoin-core_0.12.1_indexed_blockchain_block474777_and_peers.dat_2017-7-8.rar

Now run bitcoin-qt. If you don't trust me or if you have a lot of money in your wallet then you'll want to reindex it. Do bitcoin-qt -dbcache=500 -reindex #This will take a long time. If you don't have more than 2-4GB of RAM (depending on your client version) and you don't have a SSD don't do it.

edit 3: Another method! I have the file shared on Gnutella. It's the same file as mentioned above. Would someone like to try putting urn:sha1:WTJUONO2Y53SAK3ID3YCD3JYX7LLYHYC in to a program like gtk-gnutella and seeing if it finds the file? Please do ensure sharing is on in your client as you download! This is a base32 SHA1 which is different than what sha1sum produces. After downloading the file with Gnutella, the previous instructions for unpacking it still apply.

Using a recent bootstrap.dat file can speed up the initial blockchain loadup process in many scenarious, because:

• you save a decent amount of download data: The bootstrap.dat.xz is highly compressed.
• you save computing ressources: The bootstrap.dat file already contains serialized data.
• you only have to download the bootstrap.dat.xz file once and can use it to deploy multiple instances.

The compression format xz allows the decompression of the bootstrap.dat file while downloading it. To download and import/index at the same time you can use system pipes to inject the highly compressed serialized Bitcoin blockchain boostrap.dat to the Bitcoin initial blockchain loadup process.

Good work. Is this project still going on?

[Mad7Scientist]

Probably not bad, but they want $10 on their site! My price is closer to $3 if someone wants to PM me and get my download link that I mentioned earlier. It'll probably take 1.5 days to upload it here though.

Anyway, as I edited in and mentioned in detail 5 posts back I put this up on the Gnutella network. Put this in the search bar in gtk-gnutella or similar and see if it finds my July blockchain 100GB rar file. I'd like to know if it works! Gnutella searches can be slow to returns results.

urn:sha1:WTJUONO2Y53SAK3ID3YCD3JYX7LLYHYC

edit: Has anyone tried? Could you PM me if you can't find the file on Gnutella?

edit2: I have the complete blockchain up to 2017-8-20 as well. Just download the following 7.2GB file on Gnutella and unpack it in your bitcoin directory AFTER unpacking the first RAR archive. Be sure to preserve the directory structure and overwrite files.

urn:sha1:TZOOC2VV4G3LQZEXEUG65DY7VEWFCIEV

I'm surprised nobody has tried to download it yet or contacted me about it not working.

[NeonFlash]

@Mad7Scientist: Thanks for your efforts. Is there an equivalent for Bitcoin Cash blockchain as well?

Is it possible to get a copy of the Bitcoin Blockchain prior to Hard Fork. Something like synchronized upto July 2017 only and not after. I'm asking for this because after hard fork on August 1st, the Bitcoin Blockchain is not compatible with Bitcoin Cash Blockchain. However, if we can get the latest snapshot of Blockchain prior to hard fork, then it can be re-used with Bitcoin ABC wallet and only the blocks after hard fork would need to be downloaded.

By the way, let's say you import a blockchain of size 100 GB into Bitcoin Core wallet. How long does it take to reindex the complete thing? How much time would you save as opposed to letting your own Bitcoin Core installation download and sync the blockchain?

Thanks.
