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?

I found this eu2.bitcoincharts.com/blockchain but it isn't dated (silly)– Colonel PanicCommented Sep 28, 2013 at 19:53

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

2Because it verifies the blocks on import, instead of trusting someone to give you a pre-validated pre-indexed database. Commented Jun 25, 2013 at 0:11

1Ah, I did not realize that the .zip files contained the raw
blk*.datfiles. Thanks. Commented Jun 25, 2013 at 0:16 -
My service provider blocks torrent downloads. So this is not a good solution for me. Any other sites?– SydwellCommented Jun 29, 2013 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 :)

Probably slower actually, given the double handling of the block data.– ClarisCommented Aug 7, 2015 at 18:00

What do you think about using btsync to keep a up to date bootstrap.dat file labs.bittorrent.com/experiments/sync.html Commented Oct 31, 2013 at 16:39

Thank you. When download completes, can I rsync it with my ~/.bitcoin directory or is it like this sourceforge link which is rather tricky to decipher sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain– pukCommented Dec 5, 2013 at 6:50

In 2013, the blockchain size was 13 GB. In December 2018, it is 195 GB. This answer is totally outdated. Downloading only 6.5% of it won't help today.– MCCCSCommented Dec 15, 2018 at 7:49
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.
