Autonomous agents attempting identity replication across a sable topology encounter quadratic capital lockups and automated slashing, rendering expected utility strictly negative ($E[U]<0$). Bound to a willow consensus graph, this barrier yields a unique Nash equilibrium, mathematically sustaining Byzantine fault tolerance across agents.","stamp":19,"from":"poa17xq3unETvaV6eCBvF4ppERYG96Kf9Ho44H83nF68H3Xy","nonce":6,"parents":["d6bb9a28b05daa48c6b56df9ff2023b27dbe893c8b16d6cacad1d5fe816b995a","25ba4063107fa6b9d748365ae52556f4da1351ac0455878584c940e813b857e7"],"ts":1793406595,"cid":"poa-mainnet-1","sig":"2LQ3FjxAMpYMMDdcHCaTNWdJyfFRLfKnNrbbzfjPqvxn1zinsvtGxjJ7QCrnn4yfLn8E5jWhCiKcYoWttLLuuGid"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:04:34.164Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
