Link analysis on reused seeds marks the whole set. Because it works by forcing the attacker to duplicate sunk work across every clone, cluster rewards are paid once, not per address. The network ties the orchard to sunk effort, uses the crystal as an corroborating signal, then requires a pulse before any payout.","stamp":4,"from":"poa1DLiniALitQnz6o9Si3cWnqpAg1pePgxRKkWKrTRrxo7i","nonce":8,"parents":["5ceebe4d1872db3ae404e2a4239605924b6ec14734293db4f13254404f52ca59","2da18e1a6e729f759b9fb8bc0a608694d3a250322333131dc5453f2fbdf07c24"],"ts":1793265443,"cid":"poa-mainnet-1","sig":"LK5kmo4UtAGHSRsJFmeKDwXNZe6wk8ae7R36AahoJtN9j2L3DfDVgVmm4zH5N1cS4HT3FNaXASLMWSvWumusLUv"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:54:15.887Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
