searcher-builder-validator-sequencer

Notes on Searcher-Builder-Validator/Sequencer (SBV)

tl; dr

• cooperation between proposers seems unlike in an unfair market, especially in a semi-permissionless half-centralized sequencer setup
• considering slashing risks, the incentives to become a sequencer (despite tx fees) are unclear
• having a Searcher-Builder-Validator/Sequencer supply chain could lead to trusted social contracts between all actors
• should MEV be addressed on the application layer? this generate security concerns on the underlying protocol
• a fair marketplace would let searchers to look for predictable MEV state changes with profitable actions, with the security of the protocol (with the sequencer itself)
