ZisK announced on August 18 that its v1.1.0-alpha prover reached a 9.62-second p99 on four RTX 5090 GPUs, bringing it within Ethereum’s 10-second target. If confirmed on a representative mainnet block sample, this result would reduce the GPU count from roughly 12 units to four. The open-source project claims 128-bit security and post-quantum resistance, but has not disclosed workload details, block range, proof size, or measured system power consumption. The announcement weakens the centralization objection around intensive GPU configurations, though the lack of verifiable data prevents a reliable comparison with Ethereum’s standards.
