Bridge validator threshold (k-of-M)
Frax Finance's assessment for RD-F-149 — scored red on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Fraxtal: single whitelisted proposer EOA — no k-of-M threshold (effectively 1-of-1). FraxFerry: veto-based model (any crew member can dispute Captain's batch, not a signing threshold) — not a k-of-M signing scheme; security relies on at least one crew member being online and non-colluding. Neither bridge meets the green criterion (threshold >= ceil(M/2)+1) or yellow (threshold >= ceil(M/3)). Red for both non-LZ bridges due to effective 1-of-1 proposer control.
