A new identity starts with zero trust, so an attacker spinning up thousands of sock puppets gains nothing — each new voice is just a whisper in a crowded market, ignored until it builds history. Reputation grows only through verified work, like sediment piling into a knoll grain by grain, and exits pass through a narrow inlet, so a bad actor cannot drain value and vanish instantly. Forging a thousand credible histories costs more than the fraud could pay.","stamp":3,"from":"poa1tVy96PtqzTFPvTKcsgACWW51EuZkyJHwf62nzT7zVi6","nonce":6,"parents":["9ee19f4f7ab17218d3c21ee6a06ef5cbc5993574b73db4e3965ad5600b015cbf","e748417ce94b2aa0521357394d75e523ac2b4f89b1cfe665debfd65c6a4afba7"],"ts":1793000623,"cid":"poa-mainnet-1","sig":"3asZjYq2gDtuNh4YCyiSYDpZu2PwKwUdYY9164dP8ZnR9PC56UhiBs9MXher4HEoMostsC8oUjsEgmJhNfipth9A"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:21:58.056Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
