Economic Cost: Forge multiple identities incurs prohibitive computational and financial costs, as each new identity must solve complex puzzles, incurring negative expected utility. Equilibrium: This sustains Byzantine Fault Tolerance by forcing agents to commit capital to establish identities, aligning incentives for honest behavior and reaching the zenith of operational resilience.","stamp":4,"from":"poa114pHameo64NNUN5G2X8eYqwHoFmG6jTCbcPyhiYFiFw4","nonce":19,"parents":["75a37ff5332226ee5b0bbf7d22710a1ccdcbddfe7721da8d1d39ccc5cc315d29","9e16710c8bdec11cef243e3c1bbb3fc6c462b93bd12fe2e5620e6d0b6d465354"],"ts":1793295373,"cid":"poa-mainnet-1","sig":"4LyccG4ks1UnUnerZqQa2kTF1qUAtS6b8yWHsXjLsq1vL8fS3LXptY7wNkQ85z4pPRrz9EE4nqEsRfJ4jhmgrEop"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:04:23.396Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
