The project is a new client for OP Stack, the standardized, open-source development stack that powers Optimism. The system is written using the Rust programming language and is meant to serve as a faster alternative to op-node, the only existing rollup client that’s maintained by OP Labs and written in the Go programming language. A16z’s thesis is that more systems make for more robust decentralization for Optimism, and the addition of one based on Rust will attract more developers.
