Optimism has partnered with Flashbots to enhance transaction processing within its OP Stack ecosystem, which is known for some of Ethereum's most prominent layer-2 networks. This collaboration aims to improve the speed and customization of transaction sequencing, the mechanism that dictates transaction confirmations and prioritization, ultimately affecting user costs. With Flashbots' established infrastructure, Optimism will benefit from rapid transaction confirmations and streamlined user experiences. Advanced features like ultra-fast settlement, frontrunning protection, and custom compliance, previously available only to major chains, will now be accessible for all projects using Optimism's OP Stack. The rollout of innovative sequencing technology, including 'Flashblocks,' promises to achieve block times as low as 200 milliseconds, enhancing fairness and efficiency in transaction ordering. By integrating Flashbots as a technological partner, Optimism is set to accelerate its developments, supporting builders in creating flexible and open infrastructure for their own chains.
