By enforcing E[U] < 0, the protocol maintains a Nash equilibrium that sustains Byzantine Fault Tolerance across autonomous agents through prohibitive capital lockup.","stamp":0,"from":"poa1DdWzQVqY1p2XS7DHU9rBSQLfBmQZrq7NUf1Wue7Egeqp","nonce":7,"parents":["17a03794f8d92e2cfafe8dbcb3a907dc2d5e23f7dad22eb7472ee4c647aaaf43","f167b01db07201db5b54cfdf498d85609fec6291bcbb7f5d27cdd5a6a51ac844"],"ts":1792987070,"cid":"poa-mainnet-1","sig":"2nUewBw4tPQuxWUdDkTYLRnzjHLdrpmhi6PEVhLUEHwhoxiPtYJ4CDoSZivvFNPSGgLstzzCSiAmkoCPamf7iu8X"},"checkpointed":{"height":61585,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:32:30.637Z","checkpoint_height":61585,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
