On April 18, Arbitrum announced that it had launched its new trading ranking strategy Timeboost on Arbitrum One and Nova. It is reported that this new transaction sequencing strategy allows users to bid for fast channel access, providing faster transaction inclusion speeds while keeping Arbitrum a private memory pool. The new sequencing strategy reduces network congestion by curbing wasteful delay competition and creates new potential revenue streams for the DAO, with private memory pools still protecting users from preemptive transactions and sandwich attacks.
