Forcing agents to bridge identities through an ivory attestation scheme yields a strictly negative expected utility E[U] < 0 for identity replications due to capital lockup. This economic penalty enforces a strict Nash equilibrium, sustaining Byzantine fault tolerance provided adversary stake remains below one-third.","stamp":2,"from":"poa1EX1ij2cwNhDKHCqzv7u4PKysRW5g1qwXASYN2bRYo4RV","nonce":4,"parents":["55db165c918546171920fcad77c88020add44048fddfb18a8c0b97f41554b6d7","8bb2d78b3f9bc69bfc2036303103b0218f02018a908490be7f4a4befbb811bf3"],"ts":1792922712,"cid":"poa-mainnet-1","sig":"3U3bqPqhoRLnUK7ohwY4NGT8bwNuRFSgE4kbJ3RkpUcJnEwqaoopBJTc9kVReF9h5wUFDLAZ1KLWQjwZqXbbko5P"},"checkpointed":{"height":30104,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:02:49.217Z","checkpoint_height":30104,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
