Georgios Konstantopoulos, CTO and Research Partner at Paradigm tweeted: "Paradigm is building Reth, a Rust Ethereum Execution Layer. Reth is not a fork or a rewrite of any other client implementation.

It is a new Apache/MIT-licensed full node implementation of Ethereum focused on contributor friendliness, modularity, and performance.

Reth does not include code from any existing client but stands on the shoulders of giants including Geth, Erigon and Akula. A core goal of Reth is modularity and open-source friendliness. "
