Matter Labs, developer of Ethereum scaling solution zkSync, said it’s working on a Layer 3 chain called Opportunity.The Layer 3, still in the initial development phase, is aimed at further improving the scalability of zkSync's blockchain infrastructure.Opportunity will be an additional off-chain computation layer on zkSync's Layer 2 main network. Building on top of zkSync, the Layer 3 is meant to help lower Ethereum scalability and gas costs. Matter Labs said “zkSync’s EMV-compatible Layer 3 proof of concept ‘Opportunity’ will come to life in the first quarter of 2023, bringing a starfield of 10X moments to Ethereum.”
