A second price sealed bid auction uses SUAVE confidential compute, and presents results in a contract that is then accessible by preconfirmation providers on mev-commit. This achieves the credible auctioneer requirement for a preconfirming relay leader auction, where the relay leader is then able to provide blob preconfirmations for Ethereum on the mev-commit network and present them to block builders in the form of an inclusion list.
For how the SUAVE auction integrates into the blob preconfirmation flow, refer to system diagram under blob preconfs
