Optimism is working with Flashbots to revamp how transactions are processed across the OP stack ecosystem, aiming to make some of Ethereum’s most popular Layer-2 networks faster and more customizable.
Partnerships focus on the behind-the-scenes process of determining sequences, quick confirmation of transactions, which transactions are prioritized, and how much users will ultimately pay. According to optimism, Flashbots’ infrastructure is responsible for building more than 90% of Ethereum’s blocks, bringing proximity checks and user-friendly transaction orders to all chains of so-called super chains.
This is because the OP stack supports over 60% of all Ethereum Layer 2 activities, so optimistic teams claim to include some of the best-known Layer 2 chains, such as Base, Unicane, World Chain, Ink, and Sonyum. Previously, advanced sequencing features such as ultra-fast payments, front-running protection, and custom compliance rules were only available in the largest chains with resources. With Flashbots installed, these features are available through tools for building projects in Optimism’s OP stack.
Flashbots is best known for working with MEVs or for reconstructing how the MEV boost tool generates blocks.
Some of Flashbots’ sequencing technology is already live on the OP stack chain. While Base and Unicane use “flash blocks” to provide as low as 200 milliseconds, Unicane and the World Chain are experimenting with block spaces of verifiable transaction order and priority.
Over the next few months, Optimism and Flashbots plan to use the OP stack to deploy flash blocks and advanced sequencing R&D on optimist mainnets and other chains.
Sam McIngvale, OP Labs’ Product Head, said: “This is part of our broader mission: to give builders the freedom to design chains their own paths with open, flexible, and combat-tested infrastructure in production.”
