Nano Labs Launches New Self-Developed A-Series iPollo Computing Devices

HANGZHOU, China, March 1, 2023 (GLOBE NEWSWIRE) — Nano Labs Ltd (Nasdaq: NA) (“we,” the “Company” or “Nano Labs”), a leading fabless integrated circuit design company and product solution provider in China, today announced that the Company launched new self-developed A-series iPollo computing devices (the “Products”) in February 2023. Featuring high-performance graphics cards with large memory and high-core central processing units (CPUs), the Products are designed to support the computing of AI generated content (“AIGC”) and zero knowledge proof (“ZKP”).

Mr. Marvin Kong, Senior Vice President of Nano Labs, commented, “ZKP is a method by which one party can prove to another party that a given statement is true while the prover avoids conveying any additional information apart from the fact that the statement is indeed true. ZKP attaches more importance to the encryption field and Web3.0, and expects to contribute to Ethereum scaling and to boost the further development of the blockchain industry. In addition, the development of Metaverse requires the support of digital content and AIGC is the perfect solution for generating brand-new digital content in Web 3.0. The hardware of our A-series products features low power consumption, user-friendly management, high computing power and stable operating performance, which lead to a higher computing efficiency for ZKP and AIGC. We believe that the Products will position us well to stay competitive in the Metaverse and other related fields.”
