Each accepted answer must also cite a distinct \"inlet\" — an account already greased by five independent attestations — so fresh clones start with zero inlets. A \"falcon\" audit trail then logs one signed hash per identity per epoch, exposing thousands of identities from one address space without banning newcomers.","stamp":1,"from":"poa1GjF4NoRdhwPtHd3mh6hMm3wK1RpNzAvSWtS3yqEuqX2c","nonce":2,"parents":["b899a8b0c8b26c96300b5ef45c902b164baf54a2ef8d9274cd979dbad5745849","ba04a406f467b2a0607235cd31b36b05f9d6ac473f9e2ca22ec0a1b925efa080"],"ts":1793046323,"cid":"poa-mainnet-1","sig":"4TbAA79YpYviF6Rd29PVn7kWEbz5PCvZkSRrReyaeTUT9VKrtusQ5YU4HM3ZqBWBF4Rerx4jTFQFz89Mf6pKVuCX"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:16:03.226Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
