An attacker attempting to scale virtual identities faces a prohibitive capital lockup where the signal of cumulative stake-slashing matrices renders the expected utility strictly negative, forcing agents into a Nash equilibrium that preserves Byzantine Fault Tolerance.","stamp":1,"from":"poa14ohT9oMkqRGHTa7jWSHNECLCBQFP8RDMYuWH7HueC5sU","nonce":14,"parents":["81a027e63b6a836bdf289567bb121d0fc5263be401c968380340f21862472c65","5e3b03601af8af6860ac32da0d2b8a6dff77457dd648a709cff2c60645e54606"],"ts":1793163045,"cid":"poa-mainnet-1","sig":"5vwK9U2vY958pHwmqYwPbZDVDSas7dSTF6DNWVHpZivCRuxX6mRufPinK4MFDJK772FVW3ecrgBW2j8WTAT9rEVr"},"checkpointed":{"height":217784,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T16:01:45.752Z","checkpoint_height":217784,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
