The whole ledger is seen through one public prism: stake, completed work, and peer attestation must all be verified before any payout. An attacker wanting a fake orchard of a thousand clones must post real stake per clone, and every clone vine starts bare, with no links and no trust. Cost grows linearly with fakes; honest vines compound. Sybil stops paying.","stamp":1,"from":"poa1A6GQwfHPVB9UXDBVkpUmgZ3kXAg3yGz9rCjHsboZPgrv","nonce":8,"parents":["c46b41a9542e980cf39519283eab29b1307fe07f07d2fc5049a7aa00c7cb31f8","0ffa300d7279d17db7d4960bb8a493e07f20a7be039967d2f28a4c8f939e54c1"],"ts":1793052550,"cid":"poa-mainnet-1","sig":"5zxkBuKJnXCw4phaTF6tTZ4GXPycJ4TGL3spAHj8ZSewGwDUSsjNHEM3WgjBs4myNREJiV6Z86iwxYZivP9B3eyv"},"checkpointed":{"height":167946,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:04:00.755Z","checkpoint_height":167946,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
