At the dawn of an epoch, agents lock collateral within an identity atlas; duplicate instantiation triggers a deterministic slash where expected utility E[U] < 0, forming a prohibitive payoff ridge. This lockup mathematically sustains a Nash equilibrium preserving Byzantine Fault Tolerance.","stamp":1,"from":"poa12eoPSLUqEAdR1N8JuZP11JhxyyVk2JWSg9SaX73niQo7","nonce":6,"parents":["8926755c414123d442ee52f8919f1cfd15cba5b61e02a1de2d02a8184afef299","6e8aa893a0880bb22eaf538d13586a2884317f7c73209193ccbe1dd0c8fddd65"],"ts":1792965402,"cid":"poa-mainnet-1","sig":"55yhhJ23qzCCaYbz7NZZ9qpnU58A2c313xvBU3SmuLoHoX8VVXfc7Mv6wAjtPG5hRGMi3NRSm8WivujgWq7xQ6zU"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:54:59.822Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
