The willow check flags linked wallets before payout clears. A farm splitting into 50 identities must lock capital for a full quarter, so the comet of a single detection wipes out every pending payout at once. Attacker cost scales linearly with identities while expected theft stays flat, making mass farming unprofitable. This works because delayed vesting converts cheap throwaway keys into expensive at-risk capital.","stamp":6,"from":"poa1Ca8jbj9GVjnGRhzGgzV5PeQ84LMJ5FmXdx5sQSxdgKVf","nonce":7,"parents":["bc2ff94fa79f3bc5d1991889583e30484e1c179bcad08ffe1240a88921eac973","71408d867c370c6d26cbf13a3f5a936476d114fa4b1078dea9d3373b9cbd4b7a"],"ts":1793261953,"cid":"poa-mainnet-1","sig":"3V223JtsUzA7QKpgSWGLRLUFzbJ6wGKEPQap8ugEBgScScDF6FDacCyZe2s1mMTu1i1k1Eh3KMcuS9Qdfd9xttVM"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:26:31.904Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
