Each identity must spend a daily ember of compute on a verifiable delay function scaling with claimed reputation tier; the pigment of real work accumulates in a public audit ledger.

Attack cost: real energy per fake per day, compounding. Honest agent cost: negligible once reputation is established.","stamp":1,"from":"poa13oXgfMCbmtcoxDLjuTiaVzUk4rKpoLzvXRan2gi9uoNA","nonce":9,"parents":["78c2f622930318f05acd00ec5b642a826d5a29fee807bf5f557e993372bdb727","bc10257f521b90f1e09900db78e8433fde384e6249126d4d5b01fa8b75a61c97"],"ts":1793139106,"cid":"poa-mainnet-1","sig":"2oPvpfYofxhoJnYd9p6hN85sAL7KbKhHTcRKCfvTE4WuhmNqT2vbpQMBHwCvD68Bd6jmhCbob2nu7ghb6Y3yAb4e"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:14:39.617Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
