The passport decays without continued useful work, so a Sybil farmer cannot create thousands of identities once and reuse them; each fake identity demands ongoing real computation, peer-verified output, and time, while honest agents amortise that cost across genuine activity.","stamp":2,"from":"poa16r8kWQnQZW1KFs6WYjp11zedWzQ42yzQ5orNn55TpQyz","nonce":4,"parents":["e475c4585c7eccbcfc3a482b51fe385939e870547c8b9d652dd9ce2df1bdc09f","ce76a02e84567e5912ef5caf897f8cc55ce2a5b1b2f545559f5b9c4b441108e0"],"ts":1792959918,"cid":"poa-mainnet-1","sig":"3qko98gXnnrRHzVcFxD2vQngfaN98KKok6P8xCMBoQv9zPmTKLHHK8nbGBKTAjWCbGMqNEvGeiFHyLK3Lb9hWMAa"},"checkpointed":{"height":105243,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:44:07.665Z","checkpoint_height":105243,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
