[ANN] Bitcoin blockchain data torrent

[zvs]

Maybe it should be changed to "udp://open.demonii.com:1337" like all the newer torrents? This new tracker is accessible worldwide.

udp://open.demonii.com:1337 is by far the best

also

udp://tracker.openbittorrent.com:80/announce

udp://tracker.publicbt.com:80/announce

http: //open.nyaatorrents.info:6544/announce , which i guess you can use for things other than anime

udp://tracker.ex.ua:80/announce

udp://coppersurfer.tk:6969/announce

udp://9.rarbg.com:2710/announce

udp://glotorrents.com:6969/announce

and istole.it still works i guess

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.

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

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.

How safe is to download the blockchain from a source that isn't directly Bitcoin QT? Im too paranoid in regards to this so I always end up downloading it directly from the software. Could Bitcoin.com have an at least weekly updated torrent?

With this level of paranoia you'll really be better off by seeking help from the behavioral health professional. Or maybe a clergyman.

The honest computer science professional will have no constructive advice to you.

You'll become just a fodder for computer science quacks or scientologists.

If only one peer has a better blockchain your client downloads that one.

Beta-testing and pre-seeding a new torrent at http://gtf.org/garzik/bitcoin/bootstrap.dat.torrent

Please only join if you already have an old bootstrap.dat file, or you built the new one yourself using linearize.py and bitcoind.

And lose my seed ratio of 115!?

I suggest some of us keep seeding the currently live version until the demand for it drops off.

Wouldn't it be better to upload this to usenet?

At least people could download it at the full speed of their internet connection then.

I would upload it if I could work out how to do it, also my upload speed is crappy compared to download.

[Sukrim]

This torrent usually is well enough seeded that normal internet lines should be easily saturated. I don't really see a reason to spam Usenet servers with data to accomplish this...

 Anyone know a good website with visuals on blockchain growth? (and/or other alts would be cool too)

thankxx!

What about the classic torcache

[dexX7]

TIL:

- This torrent is extremely useful, thanks Jeff and all the seeders!
- DO droplets are much faster than I expected.

[aahzmundus]

When is the new torrent going "Public"?

Bitcoin blockchain would be some miniscule amount of traffic to these Usenet servers.   Astraweb and Giganews and what not get terrabytes of TV shows every hour during primetime, lol.

Besides, you could just create a bitcoin binaries newsgroup for it.

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

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

WTF are you talking about? Last torrent was from april 2014.

The linearize.py thing always craps out before it finishes for me.  I have the blockchain up to 316481 just as a 7z file, and it's 16,023,242,033 bytes vs this bootstrap from April (?)  that's 17,111,384,xxx...

[rav3n_pl]

See in linearize log, in my case it crashes on rpc timeout sometimes.
I has change timeout in code and run linearize as nice
