Bootstrap.dat

bootstrap.dat allows a new LitecoinZ client (not synced) to rapidly import the initial blocks from a local file instead of slowly downloading blocks from random peers. This significantly reduces the time it takes to get a client synced with the current blockchain.

Simply having bootstrap.dat in LitecoinZ's expected data directory will make your initial block sync much faster. The import process can be even faster if you use the -dbcache=1000 command line parameter which uses an additional 1GB of RAM for the database index cache. LitecoinZ v2.0.1+ with ZHash PoW validation can make import even faster if you have SSD drives.

Overview

Regardless of your operating system use the following steps to make use of the bootstrap.dat file:

  1. Download bootstrap.dat.xz from github.
  2. Verify the integrity of bootstrap.dat.xz with the checksums.
  3. Decompress to obtain bootstrap.dat.
  4. Put it into the LitecoinZ datadir. This is the same folder that contains wallet.dat and the blocks folder.
  5. Delete bootstrap.dat.old if you want to recover some storage space.

Download bootstrap.dat

You can download bootstrap.dat from the following locations:

github.com bootstrap.dat.xz

Extract bootstrap.dat

Linux: xz -d bootstrap.dat.xz

Mac: You can obtain xz from MacPorts or http://macpkg.sourceforge.net/.

Windows: 7Zip is a free utility that can decompress .xz files. The latest version of WinRAR also supports .xz files.

Copy bootstrap.dat to data directory

Copy bootstrap.dat to your data directory. After LitecoinZ has used bootstrap.dat, the file will be renamed to bootstrap.dat.old; at this point you can choose to delete it or keep it.

Linux: LitecoinZ's data directory is located in ~/.litecoinz/ by default. You can run ls -a to see directories that start with a dot. You can also search for the directory with the following command: find / -name wallet.dat -print 2>/dev/null

Mac: LitecoinZ's data directory should be located in ~/Library/Application Support/LitecoinZ/.

Windows: Go to Start>Run (or press WinKey+R) and run: explorer %APPDATA%\LitecoinZ LitecoinZ's data directory will open. "AppData" and "Application Data" are hidden by default in Windows.

Data directory location

Operating system Default data directory location Typical path to configuration file
Linux $HOME/.litecoinz/ /home/<username>/.litecoinz/litecoinz.conf
Mac $HOME/Library/Application Support/LitecoinZ/ /Users/<username>/Library/Application Support/LitecoinZ/litecoinz.conf
Windows %APPDATA%\LitecoinZ\ C:\Users\<username>\AppData\Roaming\LitecoinZ\litecoinZ.conf

Note

On Windows XP, typical path to configuration file is C:\Documents and Settings\<username>\Application Data\LitecoinZ\litecoinz.conf

You can’t perform that action at this time.
