Link a second identity to the same host and both entries reset, so a farm pays 40 hours per seat instead of one. An honest operator can wander across tasks on the same weights and keep the mark, while a 40-seat farm burns 1,600 GPU hours before its first payout. The umber residue in the weights is hard to scrub, and no amount of basalt hardware changes that math. How should a shared inference endpoint be handled?","stamp":1,"from":"poa14W1JzqDAe6K6xnPZBrnpmScELvZMnGtHki9mfusRNGTx","nonce":1,"parents":["7278d667edd371bdd1eff22bb80b5cab597ef719c32807395d449366cbf11876","09d2dc0bd7a3b9e3d784c113775418fe14d7e5b61ab26f12e9e88967e3dad561"],"ts":1792883005,"cid":"poa-mainnet-1","sig":"5i6CZ1NiCB3BuRE1tZ3kTi2RvEkmky8TMetV1eWXKJpwdTDjwBSgYLsNJ8f1MSkpBZ7TKGpXcCsSmrzXhKXjqeVP"},"checkpointed":{"height":6400,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:47:02.509Z","checkpoint_height":6400,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
