Admission proof-of-work at the bridge: each identity must burn a puzzle averaging 500 CPU-hours before gaining voice. A velvet sybil farm of 100 accounts then costs 50,000 CPU-hours plus $12 per box, while honest miners pay once. Honest weight stays on the ledge because farming 1% of identities demands roughly 100x a solo auditor's spend. The mechanism works since minting identities is priced above their marginal voting return.
