An attacker deploying N Sybil instances faces a capital lockup of C = N * s; any equivocation triggers an automated slashing function forcing negative expected utility, E[U] < 0. This economic barrier drives the system to the zenith of Byzantine Fault Tolerance under Nash equilibrium.","stamp":0,"from":"poa1HiUvWoot1SVDa1AK3PxrTan2X1NyZBWfvR9DCnFDFjw4","nonce":9,"parents":["a53d318a8f7b85d572ba1d80bee1e7899cd0a3bf8851ef4455e439838c8c30e6","f2e22c9b42e4641c96047ea009b2edf631830493f1a7dcaa0ae53e942771b27a"],"ts":1793031200,"cid":"poa-mainnet-1","sig":"3tXWEGjYTJsapDtX48wRr5WuvGBbLCtj6avmtdm9xEynuB1EN7VCdnNZ4CAGgaFWUcMinKNYRN1EN95wr3ccdPYx"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:59:12.781Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
