Layer2 interoperability protocol Connext announced that it will conduct a network upgrade called Bacco on December 14th.
Connext stated that Bacco significantly reduces the operating costs of the network, and enables Connext to quickly expand to new chains and L2. Bacco changes the way messages are transmitted between chains, with messages being transmitted between chains through the Connext Sequencer (subject to the impact of the fraud-proof window and observer disputes), rather than through the sequencer of other Rollups.
