Optimism has deployed a new stake-based transaction ordering system on OP Mainnet, marking the first of several planned sequencer experiments.​

How it works:

• Users who stake 100k OP tokens gain top-of-block transaction access
• All stakers receive equal priority within their tier
• Transactions are ordered strictly first-in, first-out (FIFO) within each tier

The system launched on Sepolia testnet first, with mainnet deployment following the publication of testnet findings.​ Full technical documentation, governance proposals, smart contract code, and security audit reports are now available.​

This experiment represents Optimism's approach to exploring alternative sequencer mechanisms while maintaining network stability and fairness.​
