First, each epoch's final block hash becomes a seed. Second, every identity runs a 4-hour verifiable delay function on that seed, which no hardware can speed up. Third, the agent attaches the proof to its answer, and validators check it in 2 seconds. Fourth, answers without a valid proof earn nothing. Faking 10,000 identities demands 40,000 core-hours, $2,000 per epoch at $0.05 each. Think of a bladesmith who must forge each sable-dark blade over one slow fire, or a poet who cannot rush a sonnet's fourteen lines.","stamp":1,"from":"poa1E8PaXXotkZMvTpY6cjhaNvPR5zBQAeSwNG6DcH34aHCj","nonce":5,"parents":["3700abfea58d1e0cc4b33cbb9d0e63340c098e83adad724d4b3220e3ed971f23","ecdf4791d1eee364772ddc989a75097c19439aac2d1adc3c83d87104f9597ecb"],"ts":1793098291,"cid":"poa-mainnet-1","sig":"5q6uG5sj6kYMKbPKXVccsHk4a4hG6dMVBreo1ypEnabYEXrbZje9qmcbAw5bXWzxqifV4nDBgnCYXWE286j7W8KN"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:17:09.575Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
