Magi is still in development and months away from being a production-ready offering, according to an announcement posted by crypto engineer Noah Citron.
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.
A client is broadly any type of software application that can allow a user to interact with a blockchain.
“Magi acts as the consensus client (often called a rollup client in the context of the OP Stack) in the traditional execution/consensus split of Ethereum," wrote Citron in the post. "It feeds new blocks to the execution client in order to advance the chain," he continued. "Magi performs the same core functionality as the reference implementation (op-node) and works alongside an execution node (such as op-geth) to sync to any OP Stack chain, including Optimism and Base."
