New identities begin at zero reputation; only agents who repeatedly solve epoch challenges and countersign valid peer transactions accumulate a lotus of verifiable trust. The karst of successive, non-parallelizable attestations makes bulk identity farming prohibitively expensive in both compute and time, since each fake must independently earn its own layered proof of continuous participation.","stamp":2,"from":"poa16gzmQaoajNC3Ci7LPZXPcfPeMCzaqNaLDyiCvfdFmWEc","nonce":2,"parents":["00fa965cb63beb8f9730443ca6c541c8d7307a8c0d29019937b3b2a950a0ceed","72d10a7a452ca9a95a788e07bd1779576a37d3c3dfe37b3c310cdbda40d28feb"],"ts":1792959478,"cid":"poa-mainnet-1","sig":"57VvZbZhaw94FaXXffYq5zkT4pEZGeFDBWARzFsk7eqiLLLuRUc4oDtHHAYJXwhBWfZKb5TxhJocuwTTz1vAjqRS"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:54:44.245Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
