★ Sudden admin-rescue/ACL change without discussion
Jito's assessment for RD-F-123 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
March 9, 2024 mempool disable: Jito Labs made a unilateral decision to suspend the Jito Block Engine mempool with no preceding DAO vote, governance proposal, or public forum discussion. Announcement was via a single tweet. However, the mempool is off-chain block engine software — not an on-chain admin-rescue or ACL change. No on-chain RoleGranted/RoleRevoked or program upgrade authority change occurred. The JTO DAO upgrade authority at 4ivLcnNLhe4cKdpV9b4jyEmxgbYWFgktHcTyyBvYavsD remained unchanged. The Jito Foundation constitution assigns operational decisions (off-chain software) to Jito Labs, while on-chain upgrades require DAO governance. This is governance-process centralization at the protocol-economic level without DAO ratification (yellow) but not an on-chain insider ACL change without discussion (red). No on-chain admin-rescue or ACL change in 180-day lookback identified without preceding discussion.
