This is a bitcoin bech32 vanity address generator written in rust. Bech32 addresses are 'bc1q' started segwit native addresses specified by BIP 0173.
In the following example, we are searching for an address with prefix 'bc1qp2pec', and we finally find that a private key Kz7QeGuWJMYweKxgUVskDHkw4gU9nbCkd2qnAtEjwVhQHxmub1uL can producer an address bc1qp2pecff5tgvzrqkx7ktnv3xazj4l2dcm8e2nae which satisfies the condition.
# Since all bech32 addresses start with 'bc1q', so here we try to find an address with prefix 'bc1qp2pec'
