Celo becomes Ethereum L2 with Optimism rollup implementation

Celo, the blockchain web launched successful 2020, has officially transitioned from a layer-1 concatenation to an Ethereum layer-2 protocol.

Celo announced the palmy modulation successful a March 26 X post, stating that “Celo is officially an Ethereum furniture 2” protocol. In the thread, the enactment claimed the caller protocol features one-second blocks, sub-cent transaction costs, and Tether’s USDt (USDT) and USDC (USDC) arsenic gas.

Celo first proposed this transition in the summertime of 2023, and it is present completed aft artifact accumulation connected the aged layer-1 level halted and continued connected the caller network. The caller level is based connected the OP exertion stack and an optimistic rollups implementation.

Optimism-based architecture

Blockchain rollups are layer-2 scaling solutions designed to bundle aggregate transactions disconnected the main blockchain, reducing congestion and lowering transaction fees. Optimistic rollups beryllium their sanction to their presumption that offchain transactions are valid by default, lone resorting to fraud proofs during a situation play if discrepancies are detected connected the main chain.

Marek Olszewski, CEO of Celo developer cLabs, told Cointelegraph that “migrating to an Ethereum L2 enhances Celo’s information and scalability.” He added:

“Celo transactions are present anchored to Ethereum, inheriting its battle-tested economical information and decentralization. Celo L2 besides offers one-second artifact times and near-instant confirmations.“

Leveraging Ethereum’s web effects

Irfan Shaik, laminitis of rollup protocol Interstate, besides recognized the alteration arsenic affirmative for the protocol. He highlighted that Ethereum “has the top web effects of immoderate chain,” adding:

“Layer 1s with liquidity fragmentation tin alternatively pat into the largest excavation of liquidity available, the ETH furniture 1s.“

Olszewski besides shared his enthusiasm implicit the modulation to the OP tech stack, saying it allows for “deeper composability with Ethereum-native apps and protocols.” The caller strategy is besides importantly simplified, with 365,000 less lines of codification — decreasing onslaught aboveground and, according to him, starring to a lighter, cleaner and faster codebase.

He besides highlighted that the upgrade preserved Celo’s adjacent five-year concatenation past and was carried retired successful a trustless manner. The token was besides moved to the Ethereum blockchain, which Olszewski pointed retired should sensibly summation its liquidity. He explained:

“What this means is that Celo becomes a fully-aligned Ethereum furniture 2 — by architecture, by ecosystem and by mission.“
