The SourceForge project page for Bitcoin provides a blockchain download at http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/ but this file is old/dated.

How and where can I download an up to date copy of the Bitcoin block chain?


Since v0.10, the parallel block download in Bitcoin Core is often comparable in speed to torrent downloading, does not require temporary double storage, and validates while downloading instead of sequentially.

Original answer:

Please use the bootstrap.dat torrent download. It is more frequently updated and much safer to use.

You can find the .torrent download at http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/bootstrap.dat.torrent/download

    Could you elaborate on why it's safer? – Nick ODell Jun 24 '13 at 23:41

    Because it verifies the blocks on import, instead of trusting someone to give you a pre-validated pre-indexed database. – Pieter Wuille Jun 25 '13 at 0:11

    Ah, I did not realize that the .zip files contained the raw blk*.dat files. Thanks. – Nick ODell Jun 25 '13 at 0:16
  • My service provider blocks torrent downloads. So this is not a good solution for me. Any other sites? – Sydwell Jun 29 '13 at 6:56

You can download the complete blockchain at https://flo.sh/bitcoin-qt-bootstrap-dat/

If you follow the steps described the initial startup of Bitcoin-Qt should work significally faster :)

  • It's not meaningfully faster post v0.10. – Nick ODell Aug 7 '15 at 1:44
  • Probably slower actually, given the double handling of the block data. – Pseudonymous Aug 7 '15 at 18:00

Here you go I have recently uploaded the bitcoin blockchain to sourceforge.

Blockchain & Chainstate Date: 29th October 2013

Download Link: https://sourceforge.net/projects/bitcoinblockchain/files/29-10-2013/ Download Size: 9GB (Compressed) - 13GB (Decompressed)


You can "Download the latest snapshot from our high-speed CDN" on http://bitcoin.network but it's not free. It seems to be always up-to-date.
