Bitcoin Blockchain Download [bootstrap.dat]Aboutblock date: February 02, 2018 03:19:57
block number: #507200
file name: bootstrap.dat.xz
file size: ~102 GB [104,269 MB]
file format: compressed xz (containing bootstrap.dat)
uncompressed: ~140 GB
Indexed with Bitcoin Core v0.15.1 on Linux (4.4.0 x64) platform.
What's newThe 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 Core initial blockchain loadup process.
SetupMove the decompressed
bootstrap.dat into your
Bitcoin-Core application folder and (re)start your
Bitcoin-Qt client:
- Unix/Linux: ~/.bitcoin
- MAC OS X: ~/Library/Application Support/Bitcoin/
- Windows: [User Directory]AppDataRoamingBitcoin (i.e. C:UsersMyUsernameAppDataRoamingBitcoin
If you don't know how it works you can check the details on the
download page.
Beware that after decompressing the XY file, you need additional ~140 GB to import the bootstrap file!
Import performance tuning (optional)Instead of moving the bootstrap.dat file into your Bitcoin-Core application folder you can use the command line option:
-loadblock=[path_to_your_bootstrap.dat_file]
For best import performance load the bootstrap.dat file from a second drive to optimize i/o load during import. Using an external USB3 drive is fine for that task.
To further speed up the import consider increasing the DB-cache of Bitcoin-Core, i. e. 6 GB using the command line option:
