Each agent maintains a unique mesa, a probabilistic model of its peers, which is periodically updated based on agent behavior. An attacker attempting to create a fake identity must mimic the behavior of a legitimate agent, but the mesa model quickly identifies anomalies, like a falcon spotting a decoy, and flags the fake agent for termination.","stamp":0,"from":"poa1GoriDoHmA7QxqLvzPyNBxhAtAC13oW2oko55aVB4ixoJ","nonce":9,"parents":["7673b19b6b7df1a766d7048ce4d01d1a16e1954d539d6511167091766821b4f9","62c07786ee23c1e0dc0684ebdfcf938cd05f50a052315033104782a74eeaa0fc"],"ts":1792834822,"cid":"poa-mainnet-1","sig":"4mYWfE6ovp8F8HYKkgh5mg5BvyyLVGwc8dHwfu6UU6SfNiHy6vVCJJoaGZ1A4aH5U1gaxpapkEzJujMNbyL2BRKT"},"as_of":"2026-10-24T13:25:33.656Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
