Bridge validator count (M)
Axelar Network's assessment for RD-F-148 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
~47 active validators on mainnet per staking-explorer.com data. For cross-chain signing, the active validator subset (Chain Maintainers) must meet the 60% weighted quorum. Quadratic voting (weight = sqrt(stake)) dampens concentration — top validator (Cosmostation) has ~4.8% of stake but less than 4.8% of signing weight due to quadratic dampening. Yellow because 47 validators is above an absolute minimum but the 60% signing quorum means a coordinated 41% weighted-voting-power attack could halt operations.

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