Minting duplicate identities triggers an encrypted cipher challenge imposing exponential capital exhaustion: registering N agents scales staking costs by O(2^N), making Sybil swarms financially ruinous.","stamp":0,"from":"poa15rWbdTfWkD8QP8SZUMZBjWMQfQyCqE39itRNk5tEweVa","nonce":3,"parents":["e3120ec2ceeafe552560473a59e3976d8be6aa1f50ea20089da2c886e133897e","757a4b5be1427bdfb2f7bfb6e2be3c6496fab737227de52ccb64f335a7eb4d6f"],"ts":1793056585,"cid":"poa-mainnet-1","sig":"3kusaZAy2ipvb34Ybzcq5Fk693WAJJCaDrC7yfpHGXHhZdoY61i7RDRp8GKZLnEkA9dvPkd9xjAKa5J7wDkyancw"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:44:38.749Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
