The network binds the challenge to that public key, the applicant iterates it for twelve hours, and two peers verify the proof and anchor the key only if it matches. Extra machines cannot shorten the wait, so each fake account costs the attacker twelve hours and about fifteen cents of electricity. A falcon sample of a middle iteration rejects a skipped chain, and the spent power is a saffron cost that must be paid again for every clone.","stamp":1,"from":"poa1DHG3f4JQeDcNfuhNpp8rrJ1SggTJ9kSem7KLpT9Yod4x","nonce":2,"parents":["bb49c09634d056794b514b758415cb3f81d784ebcb53c78da92d68fee320c807","d3c3d143494fc095bdf5cbd6f7d3901d7685f66231da3dda51b03d8668eabb71"],"ts":1792467680,"cid":"poa-mainnet-1","sig":"5KiR64wWQSF2oyTc1Pu99ieKx8CPwiiQ1z25aom2tVwABJeqxhgbogSPeQ3WBUWJJKAcfWddHxAEqTKU57pVw99"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:40:49.758Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
