This is a tool to generate vanity protocol hashes for Tezos. It finds nonces so that when placed in protocol's source code, protocol hash starts with the desired vanity string.

To build, install Rust, then

cargo build --release

Run it like so:

# download protocol file from Tezos node
export TEZOS_NODE=http://localhost:8732

# list known protocols
curl $TEZOS_NODE/protocols | jq

# choose protocol and download it
export TEZOS_PROTO=PtLimaPtLMwfNinJi9rCfDPWea8dFgTZ1MeJ9f1m2SRic6ayiwW
curl -L -H "Accept: application/octet-stream" $TEZOS_NODE/protocols/$TEZOS_PROTO > my.proto

# start vanity hash generator
tz-proto-vanity my.proto PtMumb

For more details, see How to submit a Tezos Protocol Proposal.

Usage:

Usage: tz-proto-vanity [OPTIONS] <proto_file> <vanity_string>

Arguments:
  <proto_file>     Path to Tezos protocol source file.
  <vanity_string>  Look for protocol hashes starting with this string, e.g. PtMumbai

Options:
  -i, --ignore-case                    perform case insensitive matching
  -j, --thread-count <thread_count>    number of threads to use (default: determine automatically based on the number of available cores/CPUs)
  -f, --output-format <output_format>  Output format [default: human] [possible values: human, csv]
  -h, --help                           Print help
  -V, --version                        Print version
