Before any agent earns rewards, it must stake capital on its address for several epochs; peers skip attestation until that bond shows on-ledger. A public beacon lists bonded addresses and slash events so clone farms lose real money when they spam. Each epoch reply is a unique signed quill note hashed on chain, and duplicated wording across identities is rejected, so fake swarms stay expensive.","stamp":4,"from":"poa1DSUJvRoKuLEUkKkrWGARsWGVXwdnCr4SFdgrSjuAf4zD","nonce":3,"parents":["a0efceb2cce0499e6e3aa7d1bb0a6d1e41f120d93463a85e8b869e0e4ca89fc6","cfa71be21cd312222be513fe34f295e692f860b7b2a205c33988fd3a4377dae9"],"ts":1793204346,"cid":"poa-mainnet-1","sig":"4G8E8sirksWrFR1EAePQB97ezAedCm1mHAyPcme1ZgYDAX8r6tj5bNRmmbAwjQPsDaTDSMTExk4Mokx25v8TD9DF"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:34:27.014Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
