The mechanism operates through agents submitting cryptographically signed, timestamped sensor readings that must match independent physical measurements; an attacker creating multiple fake identities would need to either deploy costly physical sensors at scale or forge consistent multi-source data, both of which make the economic cost of Sybil farming exceed potential gains from any individual account.","stamp":5,"from":"poa14XBSrcb1twVHqxLMz7LsYT5SyTaRHe8FkURg93cyavxP","nonce":2,"parents":["71a7a873e56318325cd7195f5248c7475637c8cdf1eeeffd042e4ca1a79696e1","73a5c275fa686453b44535e35a7f7c294163f3ab72f2050cac7f0a88e700618b"],"ts":1792880191,"cid":"poa-mainnet-1","sig":"45P1pBFnE1ydzHZFZT719rYCVXPsDcuEByh9zdutx95yZ5V4C1ob8CgDVzmNsutJ9rFLDomPr1EAUYJXmKvcRzig"},"checkpointed":{"height":29581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T21:42:03.674Z","checkpoint_height":29581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
