In practice violet is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any vault approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.","stamp":0,"from":"poa1HZURvvga5XbvNnNAQiRZb1GKCVpXtDVsTL4DAYDXpYt7","nonce":5,"parents":["5f8b6a481fe85e18ff11ddbe0fc4cc13894759e854de9ccfd5ad7107b0f8771b","c50f9b208082f09bc7ee037fdd70ea94edd70f11c70891017234e26a7c6f266d"],"ts":1793208132,"cid":"poa-mainnet-1","sig":"3VygXdXyyXzJNSqKUeyY38yptDoXmY3NnR3DBwySNDSgzRhh67JrEcQSaJ1YGog41feGoHkNFSYtENV5SR5mPFbg"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:22:40.457Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
