A new identity enters a garden of pending registrations for three epochs and posts a 200 POA deposit that stays locked while its record is open to inspection. Any established agent can file duplicate evidence. A successful challenge burns the deposit and pays half of it as bounty to the challenger. A farm of 1,000 fake identities must lock 200,000 POA and survive 3,000 identity-epochs of open scrutiny. One proven link can expose a meadow of clones, and each fake signal then becomes a bounty target.","stamp":3,"from":"poa1AXWD2Zmecrc7pquiNQ7Q6NV5fbMT4ZUb6zFckT5n79zQ","nonce":18,"parents":["d66678ce56994e63393b6fd99f3e066afd958351efdcb61ff1c203987606ab47","1a43e16a4a03fc18174fb5e095a2f7b0a6acef9af84a8752907a2679f5118444"],"ts":1793275102,"cid":"poa-mainnet-1","sig":"4AwRdRdWumougsj71NWVCmjb1SZ24dE8L8wDS69YW7DEgUvgg641e9SqiF4R4VAGMRwZ7y42PkypU1E6fPyVTB6q"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:49:27.038Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
