Download Bitcoin Blockchain [bootstrap.dat] (before Bitcoin Cash netsplit)

Even using a fast computer with a high-speed connection to the Internet it may take days to synchronize the Bitcoin Blockchain.

You don’t like to wait? Download the latest bootstrap.dat file to speed up the initialization process.

Instead of loading and verifying each block from the peer-to-peer network, your Bitcoin client can load all this information from a single bootstrap.dat file. After the process has been completed, your Bitcoin client is only loading the remaining blocks using the peer-to-peer network. This helps you to get ready much faster in many usage scenarios.

Update: I’ve prepared an updated bitcoin blockchain bootstrap.dat file which contains all Bitcoin blocks up to #478100 (Jul 29, 2017, 09:31:58).

Note: This bitcoin blockchain bootstrap.dat file contains all blocks of both Bitcoin (Core) and Bitcoin Cash before the netsplit occurred on Aug. 1, 2017. (block #478559 is the first block after the hard fork of Bitcoin Cash)

What’s new

The compression format has been updated to xz which allows the decompression of the bootstrap.dat file while downloading it. If you are an expert you can use system pipes to inject the highly compressed serialized Bitcoin blockchain bootstrap.dat to the Bitcoin initial blockchain load up process.

In effect, this means that you get an amazing deployment speed of new Bitcoin nodes. I kindly invite you to share your results…

Note

This download file has about 82 GB size; decompression needs some additional ~125 GB. Importing this file needs another ~140 GB. Take care of having enough free disk space available for this task!

Installation

In order to get things running smoothly keep the Bitcoin-Qt (or Bitcoin Cash) application closed and follow these steps after having installed the application successfully on your computer system.

Download the latest bootstrap.dat.xz file and uncompress (7-Zip or XZ Utils) the included bootstrap.dat file into your Bitcoin-Qt application folder:

Unix/Linux: ~/.bitcoin
MAC OS X: ~/Library/Application Support/Bitcoin/
Windows: [User Directory]AppDataRoamingBitcoin (i.e. C:UsersMyUsernameAppDataRoamingBitcoin

Open your Bitcoin-Qt application and wait until it has “imported the blocks from disk…”. The remaining blocks until “now” will be synchronized via the peer to peer network afterward.

Feedback on success is welcome 🙂

confirm: injection of bootstrap.dat (xz -d) while downloading it with wget works like a charm using system pipes.

Awesome!
Great option if you don’t like to save a local copy of the file!

Thank you!!
