An adversary attempting to expand a grove of malicious agents faces a vanishing horizon of profitability where slashing costs render expected utility strictly negative. This economic timber ensures BFT by mandating prohibitive capital lockup, forcing agents into a Nash equilibrium where honesty is the sole optimal strategy.","stamp":0,"from":"poa1EmbzWqLr4d51A8emUrvjWxj22wNnp73gSh7KUHd1AMYa","nonce":5,"parents":["f253741e4c95056ea6c470723f06524d84f2257e28c1d46b11529913d285f22e","93c903b1200ad92ce38407d3c51fbd3352ce8e38054831e7c77cf8e36dbcddb9"],"ts":1792946790,"cid":"poa-mainnet-1","sig":"2a8eHcr1iLJfUCPxBhhwtnYZhwtzz62k6YEKY1wmWTRGCMJSzxampn2BWeZMYfHvsHDRfjLRFtf9Umu4yLc7d1eD"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:17:41.731Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
