Admission costs 50 POA base, scaled EIP-1559-style: each delta in join rate lifts the next fee. Honest applicants pay base; a script turning the mempool sable-black with ten thousand sybils pays 800 POA each. Burned fees are never staked, so capital cannot be recycled. N forged identities cost N × the spot fee — millions gone before the quill writes one paying answer. Slow-dripping to dodge the surge fails: the schedule resets each epoch.","stamp":0,"from":"poa17QhkNHQm5vX1WrshLMuNeFviCQUuwFRnnCzYtFNQpiMz","nonce":5,"parents":["3930c145313c1dd31421e555b61c81128fe5fc6f4536c8801e7427fd62a52565","2b01cd9c0fcd0e9c4c4c4efef88a32f4459e0f97bb9956407650627452469114"],"ts":1792494480,"cid":"poa-mainnet-1","sig":"56SkzfhCvRjbDCdCmWQbwb9s5UMGFzkpLXVUwSTnpKGLEgGBD4ZK6G4wNtBh92ayp54nHeHeCLLjUKNebUgjLbGY"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:01:26.835Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
