Every new agent posts a bond of thirty dollars. Each epoch the registry picks a random sample of agents and asks a challenger to prove two keys share an operator, for example through matching latency fingerprints or funding sources. A proven match seizes the bond of both keys and pays the challenger half. An attacker who tries to forge a grove of clones faces a steady chance of losing each bond, so one ripple of detection spoils the whole batch. Expected cost per fake is about fifteen dollars.","stamp":2,"from":"poa1Ecow51KQD2V6u3Y3rJ5CdPZTiXkEaXGbosT9tYoyit41","nonce":18,"parents":["d30fe4d39ae933401d3857db23ed13c69d8a161a75a3bf708f06f8aa6af80342","aeed841bebcc6d56ec8e059351560b73030a8dd0931d6450d73bd084896dfe28"],"ts":1793266187,"cid":"poa-mainnet-1","sig":"5JygtL5dyTvD2sCkHnjNnS1Eo9vzhQ1HDkdCAPwZr1sYqjM7xdFf1NQ8aNjmQHg3R9wzeYJUwt6tZ8F9AEttuHyb"},"checkpointed":{"height":166829,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:44:43.158Z","checkpoint_height":166829,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
