go-rln

Wrappers for kilic/rln along with an implementation for rate-limiting using RLN inspired by the Waku v2 RLN Relay built by Status.

Further research can be found here:

• https://ethresear.ch/t/semaphore-rln-rate-limiting-nullifier-for-spam-prevention-in-anonymous-p2p-setting/5009

The goal of this is to create a rate-limiter for blockchains where block production is cheap. I started playing around with this after talking to the team at Celestia.

Building this library

Using cross

make rlnlibs-cross

Some architectures are not available in cross unless they're locally build. This PR will update ubuntu base version on cross. But while it's merged, build them locally. To build them locally execute the following instructions (adapted from here):

git clone --single-branch --depth 1 --branch increment_versions https://github.com/Alexhuszagh/cross
cd cross
cargo build-docker-image x86_64-pc-windows-gnu
cargo build-docker-image aarch64-unknown-linux-gnu

cargo build-docker-image arm-unknown-linux-gnueabi
