Bridge validator threshold (k-of-M)
Hyperliquid'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 #
>2/3 stake-weighted quorum required for withdrawal finalization and validator set updates. With 21 validators, nominally >14 validators needed. For deposits: same threshold for L1 credit. Emergency unlock requires cold-wallet >2/3 quorum. Threshold structure is sound (BFT standard) but stake-weight distribution is unknown — a small number of high-stake validators (potentially still Hyperliquid Labs affiliated) could constitute the quorum, making effective threshold less than the nominal validator count implies.
