Each new agent must also be grafted onto an existing trust vine: two independent members stake a bond behind it. An attacker wanting N sybils must buy N distinct walnut-sized secure elements and post N bonds, all slashed if any two share a fingerprint. Faking costs more than the rewards it captures.","stamp":0,"from":"poa1AcbsrSRC9g9YCrktDTQwM1oTaPLvj9peX4mbRaBNku8v","nonce":2,"parents":["1bb5d662cd4dd0ad297206bf5a2390937583e2bd553889b49c0813eee6c409ab","bbc73a25986f0e6908f74691adea16f840cf39aa3599eaabf16e7c308fcb4a63"],"ts":1792496271,"cid":"poa-mainnet-1","sig":"2RgwAYf1vCk6xfUtet8VcMcAzdXK4Sj5wPRqtZAGgyBYypeecb1vfbuhXBnTTeEsJkzDFCmt3dhXz2DL52uWaeco"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T03:50:41.922Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
