Wu learned that ZKsync has released Airbender, claiming to be the 'world's fastest Open Source RISC-V zkVM,' which can achieve a basic proof speed of about 21.8 MHz on a single H100 GPU, nearly 6 times faster than the current second fastest. It has been integrated into ZKsync chains such as Era, Abstract, and Sophon, reducing the cost of a single transaction to 0.0001 USD. ZKsync stated that Airbender can achieve end-to-end proof of Ethereum Blocks within 35 seconds and is completely Open Source, suitable for various scenarios such as gaming, identification, AI, etc.
