Hi, is anyone got a FRESH & CLEAN bootstrap.dat file around ? it will be much appreciated by many users ,( me included ) , since it became almost impossible to syncronise bitcoin core in a decent downloading time...even with a really good conection.
Actualy it is a serious problem for this software..
Bitcoin core developpers should have to seriously work on this..

+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.
header first syncing is already merged, so this is already fixed in the next version. There is likely not going to be a new bootstrap.dat until then...

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?
Armory likes to use it
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.

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 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:
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.

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?

thanks for this.I think that the torrent bootstrap.dat is the only way to download the blockchain now ... because bitcoin network is massively stopped by orphan block.
Very nice! I will add it to my seedbox 
1 crash after read 2To and writing 18Go (task manager open on this bitcoin-qt.exe process).
Need to restart bitcoin core ... it must scan the 18Go and keep working of the integration of the bootstrap.dat (for me, 30 weeks to process after this crash).

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. ;-)

Who cares about some arbitrary "ratios" displayed locally in a client?
Of course I posted my tip for those that care about their ratio, not for those that don't care. ;-)Quote
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?

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. ;-)
