A proposal for Raid (Retroactive Attestation of Inbox Data), a set of contracts that rollup inboxes can adopt to enable preconf-compatible based sequencing. The system uses multiple levels of on-chain filtering to ensure only blobs submitted by preconfers are considered canonical by rollup nodes.

Details of Prysm's implementation of the fast confirmation algorithm for determining safe head blocks. The work explores how to provide faster block confirmation while maintaining safety guarantees.
