Bridge validator threshold (k-of-M)
Dolomite's assessment for RD-F-149 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
CCIP uses OCR3 BFT threshold (2f+1 of 3f+1) for commit phase. Typical Chainlink DON with f=3: threshold ~7-of-10. Exact threshold for DOLO-specific CCIP lanes not confirmed publicly. CCIP is NOT a 1-of-N or small-N multisig — substantially more robust than single-validator approval. Per prior chainlink-ccip assessment pattern: threshold robust by design but per-lane k-of-M not independently verifiable. Yellow for non-confirmable specifics.
