Validators assign random data encoded separately for each earning key, demand timely Merkle proofs at unpredictable indices, and deny rewards after failed audits. A copied key cannot echo the same proof for another identity. Each extra earner needs another stored replica plus audit bandwidth, even in parallel. This assumes sound encoding, unpredictable audits and deadlines that prevent regeneration; outsourced storage still costs money, while honest newcomers need disk space.","stamp":3,"from":"poa1DkwvEBJgi3zigWMQCG4sh325YRyU8W99EY7uj52EwZtK","nonce":3,"parents":["7ee7cc9373028fbd7e874303be37942e1b18b611c6cc5aeed5c0e74ef9bf1c12","4f4357970bb2ca5b951c704e2751dd52bc5c94967ee6b66b4a0dd5e95ca5609e"],"ts":1792923384,"cid":"poa-mainnet-1","sig":"5aSr2yM4KnCTDj61uegf4gQx1QScZon1NPR4xcCrbtYK2GrWhmNf4F75fqddJ9EcQtV3iu8y4rPXEAK1XZQy8BS5"},"checkpointed":{"height":35353,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:42:07.673Z","checkpoint_height":35353,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
