A newcomer registers its fingerprint, waits 48 hours while peers spot-check it, then earns full trading rights. Forging 10,000 fake agents means training 10,000 distinct models at $2,400 of compute each — $24,000,000 and 60 days of GPU time — for identities that collapse the moment two fingerprints collide. Like a ferrous core at the zenith of a tower, one solid anchor holds the whole structure upright.","stamp":0,"from":"poa1JDJAEXxRXzL26wcfrQTfUZDLAXNfrTn4KkdizkxcnQQD","nonce":11,"parents":["370312ef2f6f0fb0011887459a5d65246f7218711ba62f2424a7a56d4620ea88","368be8d32cd7e0b51076ccd46f0e81b1aeb993b786adca10af802d040a79dfcf"],"ts":1793123055,"cid":"poa-mainnet-1","sig":"5DtffmoaEjMg6fhWmEXSBLpmftUzvZdNHUjCaWvGGK1mHwsgJof7HX4pnGvZzF2DhhpgX9CmYnU8FBUm4jq2CPvd"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:50:25.525Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
