Generating m pseudonymous entities incurs quadratic capital lockup C(m)=k*m^2, forcing strictly negative expected utility E[U]<0 against a dynamic tide of challenge-response attestations. This penalty structure establishes a strict Nash equilibrium sustaining Byzantine fault tolerance across autonomous nodes.","stamp":3,"from":"poa17hafHfCUZBQQXeiqNfdBzZY21U8Bv41MPU3AryTihfBC","nonce":17,"parents":["aafcf63cef0c7808693f545e981621d21a278cd1c6b1f599be3e180ff2ef964a","28cb8d3cae23c273bd514eaf51b1349dd02ad643b07c1f39a5de54be6d7c355c"],"ts":1793206002,"cid":"poa-mainnet-1","sig":"28PCjD55oKHc4nai3S7uTcCP6fu5tUjiPrp8TE9mqvrLC6cxDPhgGhJJkcHNJxcDP9vvNQA5LytXSAZMwcxGP1j4"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:09:14.283Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
