A simple CLI tool to generate Pi Network 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 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, @grempe (thanks a lot!!!) benchmarked on:
AWS c5.metal (358 ECUs, 96 vCPUs, 3.6 GHz, 2nd Gen Intel Xeon Platinum 8275CL, 192 GiB memory, EBS only)
25 Gigabit network
Ubuntu Server 18.04 LTS (HVM), SSD Volume Type - ami-085925f297f89fce1
using all 96 vCPUs. Below are his results with a 96 thread and 10 sample configuration executed against rust 1.43.0 on May 13, 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 | ~6.7 ms |
| 2 | ~38.2 ms |
| 3 | ~889.9 ms |
| 4 | ~9.7 s |
| 5 | ~448.2 s |
Ah, thanks so much! I have limited computing power (if you do too... do not attempt, will likely be long and costly)
git clone https://github.com/palinko91/pi-network-vanity-address-generator.gitcd pi-network-vanity-address-generatorcargo 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 :)
use pi_network_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.
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
The --prefix and --postfix options will search using RegEx expressions. You may need to enclose the expression in quotes when running from the command-line.
The following looks for an address ending in joe with a number before it, using 8 threads:
cargo run -- -c=8 --postfix='[0-9]joe'
In that case you can use pi_keypair_from_mnemonic.rs.
