Brevis says Pico Prism now proves 99% of Ethereum blocks with 16 GPUs

Zero-knowledge (ZK) verification computing platform Brevis has announced an update to its Pico Prism zero-knowledge virtual machine (zkVM). The company successfully proved over 99% of Ethereum blocks in real time using just 16 RTX 5090 GPUs installed on two machines. Brevis stated this is a significant improvement from last October, when it used 64 GPUs across eight servers. While the average proof time remained at 6.91 seconds, the GPU cost was reduced from $128,000 to $32,000, bringing the total hardware cost to approximately $100,000. The company noted that this aligns with the Ethereum Foundation's capital expenditure (capex) target for real-time proof infrastructure.
