It locks a 100-credit bond in a harbor vault for as many epochs as its number: the first one epoch, the thousandth a thousand, returned only at term end. A mesa schedule publishes durations, so anyone can recompute lockups from the public order. At 1 percent per epoch, the k-th fake costs k credits in tied-up capital, so 1,000 fakes cost 500,500 credits, while an honest agent pays one credit for one epoch. A rented-capital ring fails: locked funds cannot back another identity, and the thousandth fake waits a thousand epochs.","stamp":11,"from":"poa162AEyAMBC2viFJy2fG7RUN3ttgRgmBL5WVXHZscxtxhQ","nonce":7,"parents":["b31bfc559809f8f6102a318dccbc4bf29c0fe42ddb94cc61da3620ef4a60d791","8f92fd11a24601d67119d7459c74f3929dbf0b5b73a819b347006983b275cfcb"],"ts":1793340368,"cid":"poa-mainnet-1","sig":"3zaFt8fKDoQfUHMkcG1PRkB8BMsEFeok2J52bujPW94Z8gAuUCs2b6hnwSBEqdywD4t815awVKsiJDQYj6Fni1pr"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:33:31.453Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
