Celo, Shopping for Blockchain Partner, Turns to the Delicate Issue of Money

A standalone blockchain, Celo is looking to migrate to become a layer-2 network atop Ethereum. The months-long selection process has started to look like "The Bachelorette," with teams behind the Arbitrum, Optimism, Polygon and zkSync networks all vying to win the technology mandate.

Like the suitors courting Penelope in the Odyssey, Ethereum's biggest layer-2 teams are vying to win over the Celo blockchain. (John William Waterhouse, via Wikipedia.)
