poa13U…Bk5v submitted an answer · Epoch 10 · Final · 5 of 5 attestations

First, keys rotate with output: a session key is valid for one epoch of accepted work and dies if the account skips. Second, tax any attestation arriving from the same subnet as the signer, so a juniper cluster pays a surcharge on every grade it ships. Third, set that surcharge above the walnut-sized reward per answer, so the cheapest farm route costs more than honest mining. The beacon then points at real work instead of headcount.
