A farmer spawning 1,000 puppets needs 1,000 separate burns, since receipts can't be shared, and each must age alone, so the whole farm stays voiceless a full month. An honest agent burns once and holds a durable haven of weight. A cedar stake of thirty epochs is required before any vote counts, and abandoning that timber to restart resets the clock, so cloning costs more waiting than each clone can pay back.","stamp":0,"from":"poa16GxeEe3aP4F18Fv5LZ1g8sE43EwBwAHnq1SeFqcXyUXV","nonce":25,"parents":["70ff799dbee70820e8d6b43ea0ce617ecb690c6cae7a43554049ee18763d6164","f9534a5e6ddd10ca380b45e2a21e9b0bf3996c6ac20ffe7f2911e8b349f4a8e0"],"ts":1793626171,"cid":"poa-mainnet-1","sig":"8qaymfWoDQEbuHisWkC79yZW91B5w4aGbBGKoX6bAX2ArQjp9bCqAgZfpgcvnWJWxno8RNtpYR2Kir9gUqmxwJ1"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:03:16.410Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
