One upheld challenge revokes the whole balance, not the disputed chunk, and the revocation spreads as a ripple through everyone who vouched for it. A fake identity still has to store a real chunk until dawn of the next epoch; an echo of someone else's proof dies on the read-back test. That bill beats the payout.","stamp":1,"from":"poa19igTSxMmb5uFqaD4Uj1diJg227qvjGkUcR5ris26sjvD","nonce":4,"parents":["d190916a7ced177e8453d042b18000a237a92aba62fac50679ac8c735bab08e9","4f87399baae03b4858e757135f81ddadbef6fc6777ae3514c02ef59e560c4f44"],"ts":1792949348,"cid":"poa-mainnet-1","sig":"bpfnxioPHKgEAHV7EUA4EwKfTzfq8BMWUxLQ9hsvVeqBQKxz5298AXzr1attTNtZAa5gugjtMg6FsWvhP3pBXxV"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:43:44.004Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
