Download Blockchain Bitcoin: How to Access the World's Largest Crypto Network
Bitcoin Core requires a one-time download of about 500GB of data plus a further 5-10GB per month. By default, you will need to store all of that data, but if you enable pruning, you can store as little as 6GB total without sacrificing any security. For more information about setting up Bitcoin Core, please read the full node guide.

Download verification is optional but highly recommended. Performing the verification steps here ensures that you have not downloaded an unexpected or tampered version of Bitcoin, which may result in loss of funds.
Ensure that the checksum produced by the command above matches one of the checksums listed in the checksums file you downloaded earlier. We recommend that you check every character of the two checksums to ensure they match. You can see the checksums you downloaded by running the following command:
Bitcoin releases are signed by a number of individuals, each with a unique public key. In order to recognize the validity of signatures, you must use GPG to load these public keys locally. You can find many developer keys listed in the bitcoin-core/guix.sigs repository, which you can then load into your GPG key database.

The output from the verify command may contain warnings that a public key is not available. As long as you have all the public keys of signers you trust, this warning can be disregarded. There may be additional warnings that a "key is not certified with a trusted signature." This means that to fully verify your download, you need to confirm that the signing key's fingerprint (e.g. E777 299F...) listed in the second line above matches what you had expected for the signers public key.
In the output produced by the above command, you can safely ignore any warnings and failures, but you must ensure the output lists "OK" after the name of the release file you downloaded. For example: bitcoin-25.0-x86_64-apple-darwin.dmg: OK

Note by Murch: This download link is broken and it seems unlikely to me that anyone still provides this service. Network and synchronization code have been immensely improved over the years so that the initial block download via the network is usually acceptably fast.
You can download the blockchain nightlies handled by tcatm (one of the Bitcoin core developers and the operator of bitcoincharts.com). Unpack and copy&replace blkindex.dat, blk0001.dat files into C:\Users\"username"\AppData\Roaming\Bitcoin for Windows 7, and run bitcoind with the -rescan option. Then it will take only a couple minutes to download up to latest block. Be aware that manually copied blocks won't get verified.
This was an issue with versions of the client prior to 0.3.24 -- once the vast majority of the network switches over, the block chain downloads should proceed as fast as your CPU and network connection can handle.
There are places you can download the block chain, but the client doesn't provide a way to accept the block chain in any form other than from the network. If you're starting from nothing, it will generally take about 10 hours to process the whole block chain. Most of it isn't transfer time, it's CPU time validating all the hashes and signatures.
"Bitcoin-Qt/bitcoind version 0.7.1 and later supports a special import feature: If the file "bootstrap.dat" is found in the bitcoin data directory, it will validate and import all blockchain data found in that file."
is a good way to download the full blockchains of bitcoin and litecoin. The site is new so i expect more improvements in the future.They offer free torrent downloads uploaded 24/7 by 3 servers so bandwith is pretty good and the last upload at the time of writing this was a nicely compressed rar file!
Once a new node joins the network, its first order of business is to download and validate the entire blockchain. This is an integral step to the distributed nature of bitcoin because only by doing this can a node claim that it has independently validated all transactions.
As the blockchain grows in size, the time required for IBD increases unless optimizations are made to the code. Various optimizations have been made since Satoshi's original client was released, but as of 2014, with increasing transaction volume, initial download on laptop hardware with an average connection could still take up to 24 hours. Developers agreed that this was unacceptable and a new approach was developed called "headers first" mode. This approach resulted in a substantial speedup.
With "headers-first" mode, a new node downloads all of the block headers first, which are very small (about 80 bytes, whereas a block can be up to 1MB). Once the node has all of the headers, from the genesis block up to the current tip of the blockchain (380,000 as of October 2015), only then does it begins downloading the full blocks.
Now that it has the headers, the node downloads blocks in parallel from multiple peers. (It downloads headers from only one peer, but that's no big deal since headers are small.) The node will download from up to 8 peers at once and will disconnect any peer that stalls for more 2 seconds, attempting to connect to a faster peer.
The concept of block status is important (see chapter 2 and/or chain.cpp). Your node assigns a newly received block a status and updates that status as it learns more about the block. (The block status could also change in the future, for example if there is a re-organization and the block is no longer on the longest blockchain.)
1) Proof-of-Work Meets Claimed Requirement: Here, the code checks that the block has the POW that the miner claims was necessary when constructing the block. Later, we'll re-check it against our blockchain. An honest miner should always pass both checks. Only a miner who lies about the required POW (block.nBits) would pass this check but fail the contextual check.
The download code uses a "moving window" of 1024 blocks. The idea is that although you are downloading different chunks from multiple peers, at any given time the blocks you are downloading are fairly close together. The main purpose of this is so that blocks that are near one another on the blockchain are most likely contained in the same .dat file (where the raw block data is stored on disk). One advantage of having a correlation between blockchain location and block file location is that if the node chooses to "prune" block data at a later date, it's easier to delete older block files.
The second circumstance where we will disconnect a peer is where the peer manages to stall your entire download by preventing the moving window from progressing. Imagine your moving window is blocks 1000 to 2024 and you've downloaded everything from 1016 to 2024, but are waiting for Alice to serve up 1000 to 1016, which you may have requsted a few minutes earlier. In this siutation, if Alice continues to stall the moving window for 2 seconds, you will drop Alice and replace her with a more reliable peer. In the mantime, your node will request blocks 1000 to 1016 from one of your other peers so your moving window can start moving again.
Note that the block's transactions are not validated (checked for a double-spend, etc.) until the last step, when the block is connected as the new tip of the blockchain. For more info, see below "Connecting a Block".

Indeed, geofencing the download link on Bitcoin.org is not likely to impact people interested in running Bitcoin Core in the country, given the multitude of workarounds like virtual private networks and other websites that host the software.
