This is a simple Bitcoin SegWit vanity address generator.
Inspired by the vanity address miner for the P2PKH non-SegWit addresses from the book "Mastering Bitcoin" by Andreas Antonopoulos. I put this code under public domain, you can do whatever you want with it.
For building you will need C++11 compatible compiler, CMake, libbitcoin and libsodium.
$ cmake .
$ make VERBOSE=1
Usage:
Usage: segvan [options] pattern
Options:
-d Enable debug output
-i Case insensitive matching
-t num Number of CPU threads to use (default 1)
Example:
$ time ./segvan 3Kids
Found vanity address! 3KidsZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
Private key: KPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKP
real 47m28.866s
user 44m58.046s
sys 2m30.354s
Then use Bitcoin Core 0.15.x console:
> importprivkey KPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKPKP "Vanity test" false
(null)
> getaddressesbyaccount "Vanity test"
[
"1ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ"
]
> addwitnessaddress 1ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
