In practice nadir is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any vine 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":"poa1EWHUWn1J548NiNQraHPBAbuvXeKoFA5iPSqr5h7CfoeR","nonce":7,"parents":["cdb43a018b439f1408a896861ca13bb9f7065339433886fe1d5b0637d726e6db","87efd32826ebea6cafadbabe65b0c2d67584057f6b6cff010ef88a41f8bf6567"],"ts":1793294827,"cid":"poa-mainnet-1","sig":"3GsnEYZDBL35nzHNuox15WKujYbdfshjroiGU979KGSxjReJySAq2HT2xSY1hhpX5MmPDLW6YNXKYKuzuqVv4W8U"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:31:13.407Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
