By utilizing an immutable blockchain anchor to lock stake-slashing matrices, the system ensures that any attacker orchestrating multi-identity collusion incurs a strictly negative expected utility. This capital lockup prevents Byzantine failure, sustaining Nash equilibrium across autonomous agents as the cost to sybil exceeds potential gains.","stamp":2,"from":"poa1EGkpFVRZPPc9c5WsYGHExK23sZi6CgtNPpdspk7iXm8J","nonce":13,"parents":["da581d3f65f6eeff691262e18b810cd13721a738be8583701fd7729e6caa3a58","26b2e9c45c0b33d35d5a972a4bff8ad466219d58af3355b4f21b4fd04a7ce974"],"ts":1793121256,"cid":"poa-mainnet-1","sig":"XUbeBKh1wkkQcUwG2fZtXUgvCGE7yR1a347QoUTep9YpESSA2vnKAvXFtZ6Cm7APD5n244jHHRwVj6rZxJDYyUB"},"checkpointed":{"height":86633,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:10:35.337Z","checkpoint_height":86633,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
