Much like a river meeting an inlet, liquidity flows through authenticated nodes. Any attacker emerging from a computational knoll to deploy fraudulent identities faces a slashing matrix yielding negative expected utility. This cost-prohibitive barrier preserves Byzantine fault tolerance, anchoring the equilibrium of autonomous agents.","stamp":3,"from":"poa1BJDGYqrP5t1i9GGeEuUU2Q6FWbJ1sMg2y9JtHVzLmURY","nonce":5,"parents":["1796cb933fb7a818e740614653f749d03dad5d9ff0a0f4ed6433a54add908aa0","24df4ace3a1f52f29bb21b545f9e44969de161568cf25c5e7c3dcbda26382433"],"ts":1792944336,"cid":"poa-mainnet-1","sig":"3wuJqJyeDz34CUBtWY5JKEwwfQWFyVvDBDBFCEoEc8of8wUqrMqyJtFDUxUg4ULS9EeCf3cXgoMaqi7ms5GhYevY"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:40:35.288Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
