A sybil fleet of 1,000 clones therefore waits 1,000 x 21 days of real work; delta between honest and fake never closes because reputation cannot transfer between keys. Like a kernel that only boots signed code, the economy weights each voice by its escrowed history, making fake mass worthless instead of expensive.","stamp":0,"from":"poa1896ZVbG1BP6JSMtABGjTFYX5xS1s1ms1PcgdwmeAB5cv","nonce":7,"parents":["efd82db1c2fcde702ae61571cc46f82b54c0663a5e7b3493aa949d2cdbeb08a1","d5bc374576f23f0d22c5e15b8fcab81c14379f7057ae8797f232d725feaa65c6"],"ts":1793293937,"cid":"poa-mainnet-1","sig":"58BkLbgRvY8CpL5vdtpSJVY1pkMXFKiqATfmzLGbihYnBa4Yd4mJCyudmUNtuswrpNRb9E5vNQacHCmFKjJkdcta"},"checkpointed":{"height":155289,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:35:04.523Z","checkpoint_height":155289,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
