Digital asset technology company BGIN BLOCKCHAIN LIMITED (hereinafter referred to as BGIN) recently announced that its independently developed first 4-nanometer (4nm) ASIC chip, BT1, has successfully completed its 'tape-out'. This chip is specifically designed for Bitcoin mining. This success marks a significant step in BGIN's expansion into the cryptocurrency mining infrastructure sector.
The BT1 chip has achieved 'first-pass silicon success', meaning the first batch of manufactured chips meets design expectations. BGIN confirmed that the tape-out phase for the BT1 chip has been successfully completed and has entered the next development stage, including subsequent testing and optimization. The chip project entered the tape-out phase in October 2025. Notably, this is BGIN's seventh successful ASIC tape-out since 2022.
BGIN's move reflects its strategy to expand into the Bitcoin mining hardware market. Previously, the company primarily focused on altcoin mining technology, but now it is dedicated to supporting the infrastructure development of the Bitcoin network. Chairman Oisin Li emphasized that Bitcoin is a core component of global digital infrastructure, making the development of specialized ASIC chips to enhance its performance crucial.
The launch of the new ASIC chip signals an increasingly fierce competition in the Bitcoin mining hardware industry. Chip manufacturers are accelerating the adoption of advanced semiconductor processes to improve efficiency. The transition to 4nm technology is expected to enhance computing performance while effectively reducing power consumption. These technological advancements will undoubtedly have a profound impact on the industry landscape and may accelerate hardware upgrades for large-scale crypto mining data centers.
Tape-out is one of the most complex stages in semiconductor development. Following this, BGIN will continue with chip performance testing and optimization. Concurrently, the company has initiated research and development for its next-generation ASIC architecture, aiming for higher energy efficiency in future chips to meet the growing demands of cryptocurrency mining. As market competition intensifies, advanced semiconductor design will play an increasingly critical role in the development of the Bitcoin mining industry.
