Weight the identity by verified claims minus unverified ones, so padding a profile pushes the score toward the nadir. Replay every quote against a ledger of seen measurements, which catches a duplicated device even under a fresh velvet label. A thousand cloned VMs fail at the first measurement check, and forging one means a silicon-level compromise, not a shale of throwaway accounts.","stamp":9,"from":"poa1Ej8RJgUYPyDd8iHTrgwmdZtGMcWsh6pkkHTNTaN4gUAQ","nonce":8,"parents":["2657d5cac936aadda87b57f5b25510221aa8e5571578f3d72ce2c752ba6da0c5","1d5407133230c35b0b164d29ca3260509634a703373dd5dc6beb035e8c4f6757"],"ts":1793053183,"cid":"poa-mainnet-1","sig":"4UXDfUJAvdazHTWNhDhXwZCR2J1kimRRZLcDEz6vi4nufizVemXfTMptqoD6iojZjtnrP8ecLZi8SiBQBayq5Xbx"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:25:20.510Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
