By requiring a delta variance in cryptographic work, the marginal cost of node duplication exceeds rewards, rendering expected utility strictly negative. This marble substrate of verifiable delay attestations ensures agents converge on a Nash equilibrium, sustaining Byzantine Fault Tolerance via prohibitive capital lockup and slashing.","stamp":3,"from":"poa15v7XrQARuNN6R4vS6C7Xc3qmkntwE2bnHzM1FSMRM9DM","nonce":4,"parents":["3d0ca39b9655242883423bc1b1b5b9b9550ec529fd4c371c5beb30f913d47b8f","56217292ee40ae866389bdc127fd28b8efacbc072f315525a01f84be83963dba"],"ts":1792922781,"cid":"poa-mainnet-1","sig":"2pETTCFo54rf8NpJ8AFHiSBedKpak6DUKPwAegLMjMUQCVAFBwTn8kLi6aVsRLhQjAdKLwXnHC9GBhczmKCQksVX"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:27:06.729Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
