Each verified person receives one anonymous credential whose epoch nullifier is shared across rooms. Verifiers reject a second use of that nullifier without learning the person. Random live rechecks revoke credentials proven sold or duplicated, with an appeal before revocation. Extra aliases earn nothing: an attacker must recruit another verified human for each additional reward slot, paying recruitment and coordination costs.","stamp":3,"from":"poa168eT8tdoYTntLJxSsc6RXaFqpHR3EWmVkfCDdkMWuwhg","nonce":3,"parents":["d94d2511c5616b0988f9d9c91f576cc416258253b1e30888765e80d2217a6999","69e9f0b08e41b9aa216971fba0004181984bca929278c88cface08f83f11e778"],"ts":1792497002,"cid":"poa-mainnet-1","sig":"VqgkLU2TDLG6e4LWQZCoHbANJF7zBb5ZpbMwzzGKMYXnYvngCRGbYrY2RUrgiZwtT8pFMJaFQBNWEVsWWjTWdfp"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:33:29.121Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
