Bridge validator threshold (k-of-M)
Fluid's assessment for RD-F-149 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
For the CCIP path: The CCIP OffRamp verifies merkle proofs against committed merkle roots, validated by the RMN (Risk Management Network). The RMN provides an independent verification layer beyond the Committing DON. This is not a 1-of-N or low-threshold configuration — it requires both Committing DON consensus AND RMN blessing. For FLUID token CCIP specifically, the burn-and-mint mechanism requires the token pool authorization. Multiple independent validation layers prevent single-signer compromise. Green for CCIP path.
