This document describes the differences between the Celo L2 implementation and Optimism’s OP Stack, on which it is based. Refer to the OP Stack specs for details on the unmodified OP Stack. The L1→L2 migration changes page details the differences compared to the Celo L1 blockchain. The Celo L2 is a continuation of the L1 by using its state and providing a high level of compatibility with it.

​
Background

Since May 2024, the Celo Community has decided to transition from an L1 blockchain to a L2 solution using the OP Stack. This move, detailed and approved in CGP-133, aims to enhance scalability, security, and interoperability with Ethereum. The proposal aligns with Celo’s mission to create a more accessible and inclusive financial system. By leveraging the OP Stack, Celo L2 will retain the benefits of the existing ecosystem while integrating with Ethereum’s robust infrastructure, fostering greater innovation and user engagement.
