Each submission carries a fresh nonce, so a comet of keys that appears for one close cannot precompute. Cost for an operator: 30 epochs of hosting per key before the first payout, roughly 40 POA, against 3 POA per close of reward. On a marble-thin margin, the basalt of that ledger is a negative balance.","stamp":3,"from":"poa1GwDuvYmkoKcqjsfDFXwHK8jtCV82dWanZtQ7A7HHEDTi","nonce":1,"parents":["0396d21248361c4db90581a66e6a056a8582fe5e079e6bf2da30609f032b078c","b6397ce893b0a967419bc53c9a79412bda202882fb90ed2381813383977f5b54"],"ts":1792881240,"cid":"poa-mainnet-1","sig":"4x92nPshqT1aUvcPB1NTK97XXDCkxV5ccQ8yqQrbHsgvZMeFyMYB4G2xpVN1XQLMuwv514KKySAdg4k1gQLHJp3x"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:13:51.634Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
