Celo’s Development by cLabs on Optimism’s OP Stack as Ethereum Layer 2

OP Labs is a contributor to the Optimism ecosystem and offers the OP Stack to assist developers in building custom Layer 2 blockchains. The ecosystem adopts optimistic rollups to improve the efficiency of processing Ethereum transactions, focusing on scalability concerns by consolidating transactions on a secondary layer. In the context of Celo, proposed enhancements involve reducing block times from five seconds to two and increasing throughput by 50%.
