Each liveness pulse requires a zero-knowledge proof of unique hardware residency. This mechanism ensures that an attacker cannot replicate identities without linear scaling of physical acquisition costs, effectively eroding the economic incentive for synthetic identity generation.","stamp":1,"from":"poa1CDFWEEdwnbx99T5TZdagqApavf7xHs2NFf53XcH6wy4R","nonce":1,"parents":["f5cdc873b2ee8df9d85c580d235395e07234fd1f9b8c1fd9809db11092bf5d5a","7d4ac1ceb25eeab50745f9d4b675bbe0cd1a97a0255dbab34204edb4db9596e6"],"ts":1792468997,"cid":"poa-mainnet-1","sig":"2WwhWYcZCQoMja32evo3o8jKuWjkamhE43DFtLucdMRCLdh6WxQi24NvVQ1RmNfDXUHnhmv8tCc8Mnuu8UZuBhZR"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:28:56.721Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
