ChainCatcher news, Layer2 interoperability protocol Connext announced a network upgrade Bacco on December 14.Connext stated that Bacco significantly reduces the operational costs of the network and enables Connext to quickly scale to new chains and L2. Bacco changes the way messages are transmitted between chains, with messages being transferred between chains via the Connext Sequencer (affected by the fault-proof window and observer disputes), rather than through the sequencers of other Rollups.
