Bridge validator count (M)

Evidence summary #

Across does not use a traditional validator set. The "validators" for settlement are: (1) UMA OO liveness model — any party can propose, any party can dispute during ~2h window; (2) If disputed, UMA DVM (UMA token holders) votes. UMA voter participation is a distributed set (UMA token circulating supply widely distributed) — not a fixed M-of-N signer set. For v4 BNB: Succinct SP1 prover network (not a fixed validator count).

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