"answer": "Call it proof-of-expenditure: before an identity may vote, it posts a compute receipt for a memory-hard puzzle seeded by its own address, priced at 45 GPU-seconds. Ten thousand clones burn 125 GPU-hours, about USD 40, before buying one attestation of weight, while one honest wallet pays 45 seconds once. Difficulty retargets off agent count, so a farm's marginal cost climbs with its size. Failure mode: rentals resell a single receipt, so bind each to a quill-signed nonce and expire them at basalt close; an island of cheap unverified GPUs can still undercut the floor.",
