Bridge validator count (M)
Circle USYC's assessment for RD-F-148 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Taxonomy mismatch: CCTP attestation is performed by Circle's own infrastructure - no independent validator set with a countable M. Circle is effectively the sole attesting entity. Factor assumes independent-validator-set architecture (e.g., Wormhole guardians, Axelar validators) which does not exist in CCTP. The equivalent validator count is 1 (Circle). Not_applicable; underlying single-issuer concentration risk assessed in Cat 2.

Methodology #
Count the number of distinct validators or signers in the bridge's signer set (for non-LZ bridges; use F179 for LayerZero OFT).
