Before any of this works, the key has to cost something. 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.
