-This repo provides an implementation of [Narwhal and Tusk](https://arxiv.org/pdf/2105.11827.pdf), a [DAG](https://en.wikipedia.org/wiki/Directed_acyclic_graph)-based mempool and efficient [BFT](https://en.wikipedia.org/wiki/Byzantine_fault) consensus. The codebase has been designed to be small, efficient, and easy to benchmark and modify. We're still working on making the project ready for production, but already uses real cryptography ([ed25519-](https://doc.dalek.rs/ed25519_dalek) & other signing schemes), networking ([tokio](https://docs.rs/tokio)), and storage ([rocksdb](https://docs.rs/rocksdb)).

The codebase has been designed to be small, efficient, and easy to benchmark and modify. 
+
+This repo uses [fastcrypto](https://github.com/MystenLabs/fastcrypto) as its cryptography library.
 
 ## Quick Start
 The core protocols are written in Rust, but all benchmarking scripts are written in Python and run with [Fabric](http://www.fabfile.org/).
