Nostr CPU pubkey miner

A simple tool to mine nostr vanity pubkeys. Currently supports hexadecimal and bech32 vanity keys. Tested on Windows but should run on other platforms supported by the rust compiler without any problems. This is quick and dirty code, but works well enough.

Compilation

After installing rust, clone the repo and compile the tool :

git clone https://github.com/lacaulac/nostr-pubminer.git
cd nostr-cpu-pubkey-miner
cargo build --release

The executable will be in the newly created target/release directory.

Usage

Every generated keypair will be stored in a output.csv file in the directory the tool is launched from.

Generating vanity keypairs with the hex pubkey beginning with deadbeef using 11 threads :

./vanitypubkey deadbeef 11

Generating vanity keypairs with the bech32 pubkey beginning with npub1dead8eef using 11 threads :

./vanitypubkey dead8eef 11 yes

Running a one-core benchmark with 10000 iterations, testing generation and hex key filtering:

./vanitypubkey benchmark 10000

Running a one-core benchmark with 10000 iterations, testing generation and bech32 key filtering:

./vanitypubkey benchmark 10000 yes

Architecture

A user-defined amount of threads continuously generate random keypairs and send them to the main thread. The main thread checks every pubkey and logs the ones that match the tool's arguments into the output.csv file.
