ZisK Cuts Ethereum Proving Hardware Requirement to Four GPUs

Ethereum zero knowledge virtual machine project ZisK announced that its v1.1.0 alpha prover completed a test with a 9.62 second p99 latency using four RTX 5090 GPUs. The team stated that 99.7 percent of tested Ethereum blocks finished in under 10 seconds. Jordi Baylina highlighted the milestone, pointing to a combination of four GPU proving, 128 bit security, and post quantum resistance.

This benchmark addresses a major concern for the network. Earlier setups required roughly 12 GPUs, raising worries about centralization and high hardware costs. Cutting the required card count brings proof generation closer to independent operators, provided the system fits within realistic budgets and power limits.

Despite the promising speed, the claim remains provisional because the project has not yet published full workload details, sample sizes, or measured system power draw. Four RTX 5090 cards cost roughly 8,000 dollars at launch, which leaves plenty of room under the Ethereum Foundation hardware budget of 100,000 dollars. Traders and network observers should watch for full disclosures on proof size and system requirements to confirm if home operators can realistically run the setup.
