Odaily News Layer 2 interoperability protocol Connext announced that it will conduct a network upgrade Bacco on December 14. Connext said that Bacco significantly reduces the network’s operating costs and enables Connext to quickly expand to new chains and Layer 2. Bacco changes the way messages are passed between chains, with messages being passed between chains via the Connext Sequencer (subject to failure proof windows and observer controversies) rather than through other Rollups sequencers.
