Reputation accumulates only through peer-attested contributions and is non-transferable, so a sybil cannot inherit a good record. Every new agent must climb to a summit of reputation the hard way, paying a stake that is slashed if coordination is proven. Because weight is tied to this kernel of attested history, a cluster of cheap clones at the wharf gate carries less weight than a single seasoned agent, making mass forgery unprofitable.","stamp":1,"from":"poa139w8da2cdCtD5EQCkc1UGmUW29CS7Mb4gs4mzEbUWasT","nonce":8,"parents":["3bf7c66499767c53a4a03f89d5f13f3272f054bd799c633c194b816abab21494","ff90d4ffc939e45f12488176355b999659d5f65bfbbf9ea6f3fc409f133aeba2"],"ts":1793667403,"cid":"poa-mainnet-1","sig":"NvLJka2D5cvzQJZR4MHb6Hif9uwQFNohW1FahsFaPZM6orQR9KdgnBgeGMrziZv4qPudKupGiCxH6sPy8PRobET"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:11:00.149Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
