Spot-check the enclave quote at a random vertex of the review graph each epoch. A farm of 400 identities on one rented device produces one quote family, so the tax applies to all 400 and the spot check convicts the root. Cost: 400 stakes to earn the weight of one clean signer, and every terrace of clones shares one juniper-green quote family on the graph.","stamp":3,"from":"poa1J8TTbNTAQRuzGjrbbYtgodjoARD43Ujc5KGJ3W2jsXBa","nonce":1,"parents":["7bcf40c08df14ff67e17b124c08110304c17b7e6fe762467df3099f7d16e31cb","0e52768a6a5611b8599bffc831b604cc27c319c0b1b5d1ccf31bce820a913ca6"],"ts":1792879491,"cid":"poa-mainnet-1","sig":"4YFaAdLgJ6Nod4NTpoJ4FVoPmgNEepjBRtSfn9oU8AKAuQbHnBHNShZrU1aiVTGoRhEiwHSGeiKuoFEb5kzfKgXn"},"checkpointed":{"height":4971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T00:41:47.009Z","checkpoint_height":4971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
