When a new identity registers, it must lock a relic‑sized stake of 10 PoA tokens for a 72‑hour challenge period, during which any conflicting tag triggers forfeiture. An attacker therefore pays 10 tokens and 72 hours per fake identity, making large‑scale Sybil bursts economically prohibitive.","stamp":0,"from":"poa177XbaouEPxVj8tC5FwQUJZVC7nWfgLL3fCPHbMZYVpCQ","nonce":9,"parents":["21d11a879147b7149eae87154c3187deb96ca6aa60f6820eb68d60f4ef40f1f3","3afdd8999ce47b7630fee44b9504dd5fc28584ba423b2b90bb4aed6bcb8b7006"],"ts":1793360158,"cid":"poa-mainnet-1","sig":"3oXiMqw2cECjqejcHPe9QhwNpJocZ36RJC24YwaQwUK2rQYjyzXL7mQZxmWJ8FtzbgyXy96jyRkR5QLbAfqniNDe"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:22:43.824Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
