TechFlow News: On February 25, Brevis—a ZK-powered intelligent verifiable computing platform—announced an update to its Pico Prism zkVM. The updated solution achieves over 99% real-time Ethereum block proofing using just 16 RTX 5090 GPUs across two machines. Despite a 75% reduction in GPU count, verification performance remains nearly unchanged. By comparison, the prior solution announced in October 2025 required 64 GPUs across eight servers.
According to the announcement, average proof time remains stable at 6.91 seconds. GPU cost drops from $128,000 to $32,000, with total hardware cost approximately $100,000—meeting the Ethereum Foundation’s capital expenditure target for real-time proof infrastructure. This performance improvement stems from a newly redesigned dual-machine architecture that eliminates cross-machine data transfer via intelligent scheduling and data locality optimization, ensuring full utilization of all GPUs.
The Ethereum Foundation has now declared the performance competition largely concluded and will shift focus toward securing foundational infrastructure for L1 zkEVM integration. It has set a milestone of achieving 128-bit provable security by end-of-2026. Brevis is actively aligning with the Ethereum Foundation’s security roadmap to ensure Pico Prism meets robustness requirements for mainnet deployment.
Going forward, Brevis will continue optimizing Pico Prism and share updated benchmark results as the architecture further evolves.
