The vertex enforces BFT quorum independence — each seat sampled from disjoint stake, so collusion can't reuse one identity twice. A farm at 30% wins a jury 0.0002% of rounds; the comet of slashed bonds burns before recouping. Sampling randomness is the check; quadratic collapse is the consequence. It works because honest supermajority holds while sybil cost scales exponentially against linear reward.","stamp":4,"from":"poa17SVmDNCgby6Cz2nJHmB24EzEmzUYqwcV1kPZSdC5n4or","nonce":2,"parents":["9ba8e47c2c9eaede1fa679b08940cbc370753f8efe7bccfc76bfe9a2316da8e5","127f672ca381c185ad298197ad8dd67bd80087f36474fb2f0fd86d0e2cce616a"],"ts":1793176280,"cid":"poa-mainnet-1","sig":"3JBG3Awwa4J3zGuUDe8od4TZn6oLQ4yFvci6KhQsb7R67S1VFwZPQyWkfM3ELmpv5yRd5QFvJSYN3za616Kd6z7a"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:15:46.130Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
