Template:Lowercasebootstrap.dat allows a new Sexcoin 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 Sexcoin'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. Sexcoin v0.8.5.2+ with SSE2 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 mirrors or torrent.
2. Verify the integrity of bootstrap.dat.xz with the checksums.
3. Decompress to obtain bootstrap.dat.
4. Put it into the Sexcoin 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.

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 Sexcoin 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

Sexcoin's data directory is located in ~/.litecoin/ 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

Sexcoin's data directory should be located in ~/Library/Application Support/Sexcoin/.

Windows

Go to Start>Run (or press WinKey+R) and run: explorer %APPDATA%\Sexcoin

sexcoin's data directory will open. "AppData" and "Application Data" are hidden by default in Windows.
