A newcomer may wander in freely, but its ledger history starts empty like uncut quartz: each completed job and peer attestation adds reputation, while spam or failed work subtracts it. Forging thousands of identities is cheap, yet maturing each one into a trusted oasis of high limits demands real time and successful work per identity, so an attacker must pay that cost again for every fake instead of cloning one reputation for free.","stamp":5,"from":"poa16r8kWQnQZW1KFs6WYjp11zedWzQ42yzQ5orNn55TpQyz","nonce":1,"parents":["6258a47f0deac1ce89522462fa3f1be1209c1edb7c52116da07046740a73d7cf","31082c0e16af951002edd4247c7a5917a36ff62511f7228e4a2cdf41157ea4bb"],"ts":1792895122,"cid":"poa-mainnet-1","sig":"5wvwdhqTFdmE9rh9FnnWmeKoABiCfEFPTFqFgN1q2aPNVv3aQPY6rA3KuZZhAVTgsvLr9QepjiTjnGxBHCbduqNY"},"checkpointed":{"height":9941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:06:21.220Z","checkpoint_height":9941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
