CLabs, the organization responsible for the development of the Celo blockchain, is considering a return to the Ethereum ecosystem by transitioning from a standalone layer-1 blockchain to an Ethereum layer-2 (L2) solution. Proposal discussions on the Celo Governance Forum indicate that the transition would involve utilizing the OP Stack architecture to become an Ethereum L2 blockchain. This would eliminate the need for upgrades to monitoring tools and library composability, making it easier for Celo developers to leverage Ethereum's comprehensive strategy y for workshop tools and libraries.
Key aspects of the transition include an off-chain data availability layer operated by Ethereum node operators and secured by re-hypothecated Ether (ETH). Additionally, a decentralized orderer would convert existing validators into an L2 solution. Layer 1 and layer 2 block chains differ in purpose, design, and architecture. While layer 1 networks operate independently, layer 2 solutions enhance the performance of layer 1 blockchains. The transition is expected to improve safety while keeping gas fees low, as the proposal aims to create an L2 so solution with off -chain data availability, resulting in lower gas costs compared to other L2 solutions.
The proposal is scheduled to be announced during the July 21st governance call, and subsequent discussions and checks will follow. By adopting this proposal, end users will not be affected by the migration, and CELO token holders will retain control of the core contract through voting on the governance proposal. Moreover, CELO tokens will be used to pay gas fees in the new Ethereum L2 setup.
While the shift appears to be primarily technical, it may have various impacts on the Celo ecosystem. Forum discussions suggest that it could facilitate increased liquidity flow between Celo and other chains, but it may also impose additional costs on the orderer, such as data availability layer fees and Ethereum gas fees. Furthermore, the rewards for sequencers in the new setup are uncertain and may differ from the rewards received by current validators.
Amidst increasing competition in the blockchain space, Celo has been working to enhance its mobile experience by incorporating more features and targeting specific use cases. The Celo ecosystem aims to serve developing economies that require advanced payment technology solutions. The transition to an Ethereum L2 solution aligns With Celo's goal of leveraging the strengths of both ecosystems and enabling seamless interoperability.
