OP stack

From CryptoWiki

"The Coinbase and Optimism teams had already been working together for more than a year and contributed heavily to the development of EIP-4844. Also called Proto-Danksharding, EIP-4844 will decrease L2 transaction fees by 10-100x. Coinbase is now a core contributor to the OP Stack as well, joining as the second core project team. This furthers Optimism’s vision of being a super-chain, where the OP codebase is continuously forked to create new chains that are optimized for different use cases. These new chains, such as Base, will have seamless interoperability with one another since they all use the OP Stack."
