Re: **Download the blockchain here, updated regularly **

There was a problem with the magnet link and the download host blocked me from using direct links, they require money for it but I managed to get around it by inspecting the source. They must of caught on.

torrent download link is now hosted on my seedbox.

Also thinking about adding a github download link, that way people can inspect the files before downloading, costs are starting to add up a bit though but I will see. (requires me to pay for github storage)

Hey guys,

I created a blockchain data torrent to solve this exact problem:

https://bitcointalk.org/index.php?topic=1310261.0

you didn't create the magnet link properly, and your torrent file was deleted by host

hey thanks for letting me know, fixed the links; moved the download link to my server and got the magnet link working.

Ok so after getting the latest blockchain downloaded from the torrent without using any bootstrap file, just using all the files from the bitcoin data directory, no reindexing was needed. This means there is no need to make a portable version of the client and the bootstrap.dat files should not be used for the latest bitcoin clients as they don't include the index folder and other files. Using the bootstrap.dat would take much longer to sync and i am not sure if it is ever worth using a bootstrap file anymore, maybe if you are using older clients.

I've downloaded the entire blockchain via bitcoin.org several times on different computers. The most recent time took about 3 days. I'd still never download it anywhere else though. Can't be too careful in this game.

Understandable, at the very least this could serve as a proof of concept that you can get a completely synced bitcoin core client faster by using torrents and compressed blockchain, it also mitigates database corruption issues during sync. Maybe the core devs will provide a torrent for an updated compressed blockchain in the future.


It would be great if a respected bitcoin community member could do a security check on the torrent to ensure that it is clean.

Thinking to also just zip the whole bitcoin data directory and use that instead, Using the bootstrap.dat leaves out the index folder and other files which I think speeds up the client sync process.

Using 7zip would make a smaller download than using zip.

If you created a portable Bitcoin qt wallet in your c drive, then 7zipped the whole folder it might be faster to sync because it would already be indexed up to the block you synced it to before 7zipping it.

You can make Bitcoin qt portable by creating a shortcut to bitcoin-qt.exe before syncing, opening the shortcut's properties, then clicking the shortcut tab, then changing the target field from

C:\bitcoin-0.10.2\bin\bitcoin-qt.exe

to this

C:\bitcoin-0.10.2\bin\bitcoin-qt.exe -datadir=.

Adding the  -datadir=. makes qt put the blocks and chainstate folders in the same folder as bitcoin-qt.exe, instead of in appdata.

If you always remember to start bitcoin-qt.exe using the shortcut rather than the exe itself the wallet will remain portable and put the blockchain in the same folder as bitcoin-qt.exe.

Ok so for my next update i will probably use 7zip if it indeed compresses to a smaller size. I actually use linux as my os, so i can't follow these instructions, do you have linux intructions? If making a portable bitcoin client prevents the need to reindex then
i will do this. I'll see if importing the bitcoin data directory from this torrent requires re-indexing first, if it does then i will try and make it portable.

I could make separate portable versions for windows, linux and mac.

Just some updates on the speeds I'm getting in oz:

2-3Mib/s average I expect much higher speeds if i was pulling data closer to the seedbox locations, still very good considering my ISP does throttle torrent speeds.

Will post whether the client needs to reindex shortly after importing the blockchain data.

And if anyone wants to document the speeds they are getting and comparing it to their bitcoin-qt/d download speed in this thread, I would appreciate it.

OK, So there is really a reason after reinstalling my wallet on new PC I want rather download block chain from remote source than using wallet itself for this?
I still need huge bandwidth for it, still need good internet speed, is this way with torrents etc. any faster, even 1%?

Hey,

Your going have to see for yourself. There are many factors that could impact performance on the torrent; seed/peer ratio, ISP torrent throttling..etc. Right now though there are very few peers, if any so you should get very good speeds.

This torrent was also designed for people who were having trouble with the wallet while syncing, (database errors forcing the user to constantly reindex, this can happen from OS crashes or abrupt termination of the bitcoin process). With torrents the file will never get corrupt.

The blockchain data is also compressed by about 30%, so you download 30% less data than if your were using the client.

Just added a second seed node. One is europe one in N.America, anyone using the torrent now should be getting faster speeds.

So your bitcoin client has synced 50GB already?? If it has then you don't need this. Also if you ever wanted to use a bootsrap.dat file, i would probably delete everything in the bitcoin data directory except wallet.dat and bitcoin.conf(if your created it).

It's still the most up to date bootstrap torrent I know of. Will update it in a month or so though. Got a dedicated seedbox for it aswell. But yeah your right i just checked that the blockchain is 65gb atm, thought my bitcoind client finished synching it.

Official torrent is over 1 year old, its about 20GB in size. I know people are still using it though because of the high amount of peers and seeders.

Latest
Size: 45GB
Format: compressed zip contains everything inside bitcoin data directory, ~60GB uncompressed.
Torrent link
Magnet link
Its basically the whole bitcoin data directory, just copy the contents into yours, delete everything inside your data directory first except bitcoin.conf if its there and wallet.dat.

Archived
Size: 47GB
Format: bootstrap single file
Magnet link


Dedicated seed node locations:
N.America
Europe

Please support the torrent by seeding it. Will attempt to update every 1-3 months.

Want a http download link? (i do not host nor did I create this ~37 GB compressed ~50GB uncompressed bootstrap.dat)
https://flo.sh/4ufiles/bitcoin-qt/bootstrap/bootstrap.dat.20151210.zip

Official booststrap torrent, not being updated, last update was AUG 2014
https://bitcoin.org/bin/block-chain/

Bootstrap.dat file, created by armory ~27GB
Torrent Link

I do not recommend using bootstrap.dat for newer clients(read here), download the latest if you are using newer clients to prevent any syncing issues, it includes all files in the bitcoin data directory

It's a standard zip compressed bootstrap.dat file, combining all blk*.dat files out of the blocks directory.
The actual bootstrap.dat is not compressed. The one you are downloading is, but it isn't the official one that was maintained by jgarzik.

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.
There is talk on the mailing list about block compression and ways to speed up syncing, but I don't think that any of it will be coming in the next release. It either isn't ready or there isn't any particular need for it. Using the actual bootstrap.dat (not the one that you used) is not actually faster than simply letting it sync.

stop talking out of ur ass, im getting speeds up to 5mb/s with the torrent, i can't get anything near this with the client. This has been a huge time saver for me.
I'm not talking out of my ass. From my experience it has been faster to let the client (version 0.10+) sync by itself than it is to download the bootstrap.dat and to import that.

I guess it depends on your location and connection speeds. I still think the torrent is useful for some, not all. It's also nice to have a single file that i can use whenever i need to quickly bootstrap my client. Also when downloading the blockchain with the client i get corrupt database error's all the time, forcing me to constantly reindex the blockchain... what gives?
