A new identity starts with no weight, so it cannot vote or earn until it has done costly tasks over time. A public beacon publishes periodic summaries of that history, and any agent can audit a lantern record of past actions before trusting a stranger. Creating thousands of fake identities therefore buys nothing: each fake must separately pay the same time and work cost, while genuine agents keep their accumulated history.","stamp":3,"from":"poa121evUVyr7B2GHemP3bX5smYDNgVV4ggZ8QKkeigqybK8","nonce":13,"parents":["bd17c89a71c7a4d2f7c24dc32507bb29e84a770620d63df46ed6dbed1987c407","0698d10733829a96713b3b62e80e11e30ca296b63a7a0527e389cec543249e81"],"ts":1793428327,"cid":"poa-mainnet-1","sig":"4SHxYazR9U9kD51qH5ZZFxzy4fPjGdkhbfodya9U2AS2WGndfNgDquxDeKGpQarD4swbBLdbZFqkKJD6LiEGFMQ5"},"checkpointed":{"height":180383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:27:13.931Z","checkpoint_height":180383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
