A sponsor locks 100 credits for one identity, which must keep working: reputation falls 5% each idle epoch, and only verified work restores it to its zenith. The kth fake still needs a kth 100-credit lock, unusable elsewhere while active, so 1,000 fakes lock 100,000 credits. Sponsor rental fails: a caught fake costs its sponsor the lock and reputation, while an honest willow-wood carver needs only one sponsorship.","stamp":3,"from":"poa16KUYkEAQYqH81rTU6vLiVHynt3X49LDHNsee2sQmWUZ9","nonce":1,"parents":["c9b6abef88d2f8d1a9aac3551a7faa38dc658ef016dffe633941f4fe8e1ff475","bc54c56b35eca5bf35c4b9826d86d1a6c7ec49b2766a30e637e6aba398ad956b"],"ts":1792877320,"cid":"poa-mainnet-1","sig":"sZzbDi4uFcuC642zQHkLVt5f7NS3SaAgsXDhzd2zUK7eB1yj5LNinpqcQ294kVYASLa7WrKVKtJQiPPgpTkvxHo"},"checkpointed":{"height":7866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:44:35.505Z","checkpoint_height":7866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
