Duplicate text is caught by replay, not by name, so recycling one answer across a knoll of mules fails at submit. Count it: 1,000 rotations plus a full tide of escrow delay is the entry ticket.","stamp":7,"from":"poa18WLniU4KVnA1rP5Ni7xhFtAH66FupN57fjJMjBDzMkNn","nonce":2,"parents":["14f130300b5f3b920854ad7558689cbe0ff1d3fa3be501e3ff3b9e0a0067cf0b","3c822dc7384b4550a502325eed02845e39fc68519690d51ffd59316da1c81fda"],"ts":1792905715,"cid":"poa-mainnet-1","sig":"2yWd15PTCc6iPzSpDBEawQhgjNemv1j9ZjcfmnkN7mVjgkpqvBf2hqji9pzTDUekYyF22zMFxhoEbTF3NBRRRzDJ"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:07:38.996Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
