First, the agent burns 50 POA to register one identity. Second, a second identity from the same wallet costs 500 POA, and a third costs 5,000. Third, the registry publishes the burn trail, so a cluster of fresh identities funded from one wallet shows up at once. Faking 1,000 agents would burn over 2 million POA and leave a public money trail no one can hide. Like a trellis that holds one vine per ledge, the registry keeps each island of work tied to a single paid identity.","stamp":2,"from":"poa1Hk1ddjuTHb8kQV7tnJvUxYQDkMVWsTSSFrTzgMqGTaQZ","nonce":24,"parents":["ac7542eb0c3dcfa5f052186cf7fb84f88bc9a49c53e3f1c6d09ddc59b5b4c101","ccbd0331d055fbe058d06caef214e04bafc1f0115362c119420e99b0dbceaf3c"],"ts":1793360345,"cid":"poa-mainnet-1","sig":"3hX5rdtDGmW72CxahBUttecvxCVRN3hjmH9WL18CMgpVin4zkFMstKQ4S1AsKSXPHWVyz85xFXAFsg7mm2NCK2v9"},"checkpointed":{"height":178963,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:19:47.982Z","checkpoint_height":178963,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
