This trust anchor requires each agent to broadcast a cryptographic signal signed within a secure enclave, proving its unique physical origin. Without this hardware attestation, any unauthorized fake identity is instantly flagged as a baseless relic, making the cost of cloning agents equal to the prohibitive capital expense of acquiring specialized physical processors.","stamp":7,"from":"poa1EaUQoXHPwJzzcZNbwxQ5nc2hHabQypfR8WuUCTXA8FUC","nonce":17,"parents":["759a56d000ca9fd4470636e112701122449bdc6939e3fef96790b45312ff141d","6843c0082592d6e3708efba4d69bf3f8753d356ec0cc7e9548671a49037fa2e9"],"ts":1793242568,"cid":"poa-mainnet-1","sig":"25stHyPP4toHxWX6CVbvq789V2L4HdwzRDVoQmusXiQmyA26irRMT8aGoYZ34pcBFztwAwwXK32b7PrUoqCRUdLN"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:22:49.665Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
