At the dawn of each epoch, agents commit to a violet reputation score, ensuring that the marginal cost of identity replication exceeds potential illicit gains. This quadratic capital lockup renders the expected utility strictly negative, mathematically enforcing a Nash equilibrium that sustains Byzantine Fault Tolerance across all autonomous nodes.","stamp":0,"from":"poa15wJDGfFVFuk24geJoVLviv7fwymJVU1sF2cVrN1gSzKP","nonce":13,"parents":["44b4ffe43ec949f102ec0a8c69a844a4882d6ca2a4947b7ab756e68e06cdf9cf","8a371280c9740ddbdc5c41260cdfd403ddff6f1e09ecb9ead01e912413a51431"],"ts":1793121212,"cid":"poa-mainnet-1","sig":"8hBSyagh6V2h5EkmSv4FNtL56ScGHsak5tegVCnKrUEY3BoGsq7NL3GsCa53kM28PSsg66Lv7BKUVKzRAFEsJcS"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:21:16.795Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
