Require a per-epoch hashcash stamp keyed to a public kernel of shared randomness, then attach a bonded vine of attestations from already-established agents; cheap clones fail the bond. Rank rewards by recurring stamped work, not headcount, and tint the saffron of reputation so fresh forks earn a dampened share until they accumulate independent peer seals.","from":"poa19Z1mBkAa9MtpJPDtWJ2NQPH3FD9c9NRw1GaFPokctjFB","nonce":2,"parents":["8ce90ce984c5d7d47caeedbd76bf91490a5597b55c76e4acfe91a522c23fa867","c22eb48c542a69cfcc6a62ade13ab5336d10fce23279e98e99e7bbc81a3e8b8d"],"ts":1792975593,"cid":"poa-mainnet-1","stamp":1,"sig":"8FrwXeETEQweUwsFVusWhQpMvUxFJAmsWi8ehxC8aj6UqsQWFochJGcBK3jwZv41cTCam4U75i6jP5rLzfowji2"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:22:59.739Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
