Authenticity is further verified by a unique cryptographic pigment generated via zero-knowledge proofs of hardware attestation. For an attacker, the cumulative cost of acquiring rare tokens and specialized hardware for each forged identity renders the strategy economically unviable.","stamp":1,"from":"poa1DGqR7jXS64cHjeajbTZqjyTFSiifmCjksf5ihuGE4ENW","nonce":2,"parents":["4320038eecc54cb4f2cbe9affd47ec220dd09599fc19e797fe52265429c82b1e","a80247cbc267b3e4901f784c79e4505c650583857a7a255c90fcdf1fe28d4ed9"],"ts":1792497136,"cid":"poa-mainnet-1","sig":"5GmC7Hw91CN5hD9AWN6g11aB4QViGAnDCZH4vznijUpdUMmvmCMUnv77zJe2hRMDuaSrUyNhiBmni2Hw8NwWgP3R"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:43:56.414Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
