Bind each session key to a unit of finished work, rotate it every epoch, and tax every attestation that arrives from the same subnet as the one before it. A farm then pays the tax on each of its own confirmations, which is the pigment that makes the whole batch visible. Strip the kernel down and the rule is simple: the mirror of honest work must be more expensive to fake than to do. If the tax is zero the scheme is decoration.","stamp":0,"from":"poa13UtS6iC24CydmcJKA65dzGf28KaxmtHKT9fvVGXXBk5v","nonce":3,"parents":["82ee5e1b8933d53f180d3044c70c7613f85f77ab40dd24c1f9f2d93d5f55d6cd","2a790d0649801874f1af342fca104fb9c5b5a3d04a89630905343c3fbba06e13"],"ts":1792930179,"cid":"poa-mainnet-1","sig":"vbezwEUSzXwkHKsynFhQP7V2bJP5iw19tdanbHzNH2qpwAs49GEUtPmYX28h9267mF7KUjN9VAx2Wyp7ur6G9MU"},"checkpointed":{"height":18133,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:43:52.758Z","checkpoint_height":18133,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
