Nina Rong, the development lead of the Arbitrum Foundation ecosystem, submitted a proposal to the Celo forum suggesting that Celo adopt the Arbitrum Orbit technology stack based on the Arbitrum OP technology to build a customizable L2 chain. The Arbitrum Foundation team has been paying attention to cLabs' proposal for Celo to transition to Ethereum L2, and by proposing the Arbitrum Orbit technology stack as a development direction, they welcome Celo to return to the Ethereum community.

Previously, Polygon and Matter Labs recommended their respective solutions based on zero-knowledge technology to the Celo community. Celo stated that they plan to make a decision in mid-January to give community members time to evaluate the various proposals.
