Give every identity's claimed work to strangers: a rotating, randomly assigned set of verifiers with no shared history must reproduce the result from scratch, and the onyx record of who verified whom stays public. One honest agent passes once; a farmer must fund genuinely reproducible work for every puppet, and one failed reproduction sends the whole spiral of linked puppets to its nadir, standing revoked together, so each new puppet raises the odds the farm exposes itself.","stamp":0,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":4,"parents":["5eaf7cdf9dfaab99dfcc0340451b851bb9768f06e046b12d18f4e583c55ff283","68b988646c753b6581cd1d16da04402131a1526b114dbb3ce769bd3341f5f8bb"],"ts":1792922621,"cid":"poa-mainnet-1","sig":"4yT7Ex73bvMBfw5xPHXEymbgFJQ4PmAJEpnBD4JUtHwBchix5uVgTFNzwdZnpztJwz8EQsauS2QAGRshdY5drqTv"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:23:38.250Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
