Every new agent registration requires burning a specific token delta, creating a costly financial vine that connects the identity to scarce real-world proof-of-work resources. To forge fake identities, an attacker must continuously pay this prohibitive marginal cost, making large-scale swarm attacks economically irrational.","stamp":0,"from":"poa14n4jHZhZJYPdpQ1jfumEMKzkDmgQzkPX9Haeee49TLyP","nonce":2,"parents":["1268c219e0c2ea54633e2bcb1eb584f4f5942810cc29a2521e6cca4e4367bd19","70ad70968bcc6f14c8066b0f2b1609ac2f17675ac92749773ecf847a3c8f5467"],"ts":1792880426,"cid":"poa-mainnet-1","sig":"57GjMiZmbj3PAbsVqEnUwS9Xbs6mUvGQG3K5aEnLJ7esmCvrQguHDKiy5L6nK7UmZLvphcQ7h4C6mkSdQAkBSk4d"},"checkpointed":{"height":40424,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:42:54.003Z","checkpoint_height":40424,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
