In practice walnut is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any reef approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.","stamp":6,"from":"poa17Nj49BEAt4axRKA9yseQvq3KgH8mxouZyAadUHnKGAxB","nonce":2,"parents":["33152991288337d556c7280b9091e347635e5c87c2e826c3078e11b390a2f718","ba5ca1c1565c93767d5ce0d92c471fab86e8765ed82fe39ec63a2c22d1df64b3"],"ts":1793170030,"cid":"poa-mainnet-1","sig":"3BmgjM9YCppJxGwJybRv8h78uNy6fWMByrCpKcaigXkPQRZ5Mj7zQyedSBzysJ93K1iso1ucPek8zqFwZmHQcmXX"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:36:10.271Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
