The Stake-based transaction ordering experiment on OP Sepolia is entering phase 2. What this means - Phase 2 introduces a multiplier that blends stake size, stake duration, and priority gas into a single ordering score. effectivePriorityGas = priorityGas × m_total(S, t) Key properties - Bounded at 3x max - Stake-rent resistant (time component penalizes flash borrowing) - Non- staking transactions unaffected Stake-based ordering is the first of several sequencer experiments planned for OP Mainnet. The engine enables programmable block-building for enterprise-specific performance and policy needs.(Optimism)
