Stellar Vanity

A simple CLI tool to generate Stellar vanity addresses.

Vanity Address: similar to a vanity license plate, a vanity cryptocurrency address is an address where either the beginning (prefix) or end (postfix) is a special or meaningful phrase. Generating such an address requires work.

Benchmarking

Benchmarking is performed by using criterion.rs via cargo bench, which executes the benches/benchmark.rs file.

To see how things actually perform, not just in theory based on a random chart from the internet, I benchmarked on a CPU-intensive Ubuntu 18.04 box with 32 vCPUs, 64GB RAM, and 400GB Disk. Below are my results with a 32 thread and 10 sample configuration executed against rust 1.43.0 on May 12, 2020. Using only 10 samples is a weakness in this benchmarking example - will need to increase for a more accurate testing in the future.

prefix size measured time
1 ~3.6 ms
2 ~47.4 ms
3 ~1.0 s
4 ~26.5 s

How can I Benchmark?

Ah, thanks so much! I have limited computing power.

  1. git clone https://github.com/robertDurst/stellar-vanity-address-generator.git
  2. cd stellar-vanity-address-generator
  3. cargo bench

Benchmark Configurations:

  • as many threads as possible (see note below)
  • 25 samples per method
  • 1 - 6 prefixes

Note: this uses num_cpus::get() from num_cpus to determine the maximum number of cores availible. If that is not desired, you'll have to dig in and set this number manually... or open a pr if you know how to pass CLI args to cargo bench :)

How to use library:

use stellar_vanity::vanity_key::AddressGenerator, deserialize_public_key};;

let mut generator: AddressGenerator = Default::default();
let keypair = generator.find(|key| {
    let public = deserialize_public_key(key);
    // any conditions go here
    public.as_str().ends_with("RUST") // e.g. find address with the "RUST" suffix
});

This will continuously loop until a key with the desired properties is found. Once the vanity address is found, a keypair will be returned, which may be deserialized with deserialize_public_key and deserialize_private_key respectively. Note, this is a synchronous function.

How to use CLI:

cargo run -- [--postfix=<POSTFIX>] [--prefix=<PREFIX>] [-c=<NUMBER_OF_THREADS>]

Either `--postfix` or `--prefix` option is required, while thread count is optional.

As an example, the following looks for an address ending in pizza with 8 threads:

cargo run -- -c=8 --postfix=pizza
