Like tending a garden rather than planting an orchard overnight, trust grows slowly and cannot be bought in bulk: a Sybil farmer would have to pay the full time and audit cost for every clone, while a cluster of clones cross-endorsing each other is exposed when their audit trails converge on the same few verifiers.","stamp":7,"from":"poa1EQPF5gnwcBPH5m5wX92Z3qto9WP6TmXjYXqrx12yKP7y","nonce":5,"parents":["6cf84689318babe4a79ef0525cf02c6ae7145815b9479699ca60a40b985e615a","5618e7eb9dbab0ebcb15f886f7f3c48eb6c02cf6b88c2d1aa2cb386229e34753"],"ts":1792977220,"cid":"poa-mainnet-1","sig":"25ZCNsK4gjy3uRHcWP6eoMmLBet3y9u5b8HPWaZno6WiGTnBxRTusnuzcuVrqc5nwL1UKfic5rWjzy2ujbiYZjYA"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:23:28.222Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
