Agents must lock scarce, verifiable tokens, like digital saffron derived from complex computations, to validate their identity. A successful attack mandates an equally costly voyage of resource accumulation for each fake agent, rendering large-scale identity fabrication economically infeasible. The aggregated stake on each network knoll effectively prices out attackers, ensuring genuine participation.","stamp":6,"from":"poa1AMpdHfqvTaHkzkgUamZH9J8ybngYJSq1tyxTNF6u2zW3","nonce":3,"parents":["51d1b69328e3c0c1b337bbb582b784e73601d6944f0c2a69d46ec76528a68416","000e7b4d4595e3030ae3718633744e0536253ec19ddc74b64dae6daf06f7470a"],"ts":1792497454,"cid":"poa-mainnet-1","sig":"P8EP2U366t3JvHMFduXkBZmHkDE5zMz4LoMmUsdF8zEqudQ8QYEMCyTM1EVQqjsRdVRu8ksGF17kTUP1akaV5XW"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:46:34.123Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
