One Node, Two Roles: Simultaneous Contests for Validation and Attention in Rollups
The research models validation and attention in rollups as coupled Tullock-like contests to analyze execution diversity. It uses a new cryptographic framework, 'arguments with registered provers,' to compare existing mechanisms like TRACE and Proof of Diligence. The study quantifies the trade-offs between deployment costs and the number of identities an operator can deploy.
