BGIN BLOCKCHAIN LIMITED Announces Successful Tape-Out of 4nm BT1 Bitcoin Mining Chip

SINGAPORE, March 17, 2026 (GLOBE NEWSWIRE) -- BGIN BLOCKCHAIN LIMITED (("BGIN" or the "Company", NASDAQ:BGIN), a digital asset technology company with proprietary cryptocurrency mining technologies and a manufacturer of cryptocurrency mining hardware, today announced first-pass silicon success in the 4nm BT1 Bitcoin mining ASIC chip—the Company's first proprietary chip designed specifically for Bitcoin mining. This achievement marks an important milestone in the Company's Bitcoin mining chip program, which entered the tape-out phase in October 2025 and has now reached first-pass silicon success.

With the tape-out complete, the BT1 has now entered system-level testing and production preparation. This achievement represents the Company's seventh consecutive successful tape-out across its ASIC mining chip programs since 2022, reflecting a strong track record of execution.

"The successful tape-out of our BT1 chip marks a significant milestone for BGIN as we expand into Bitcoin mining infrastructure. We are advancing our strategic evolution from peripheral hash power toward mainstream mining infrastructure," said Oisin Li, Chairman of BGIN. "Altcoin mining was our training ground; Bitcoin is where we apply those lessons at scale. From Altcoin to Bitcoin, this reflects the natural progression of our engineering capabilities and a strategic decision to focus on the most resilient and infrastructure-driven segment of the digital asset ecosystem. We view Bitcoin not as a speculative opportunity, but as a critical layer of global digital infrastructure."

"With this achievement, we have completed one of the highest-risk and most capital-intensive phases of chip development," said Allen Wu, Chief Executive Officer of BGIN. "This demonstrates that our R&D execution in advanced process nodes continues to advance within the industry. We are now conducting comprehensive performance and stability testing of the chip, followed by system-level integration and optimization to ensure mining machine performance in optimal operating conditions. Our mission is to offer best-in-class value in this industry sector through rigorous cost control."

Achieving first-pass silicon success helps reduce development risk, supporting the Company's confidence in executing a multi-generation Bitcoin mining roadmap. BGIN has also begun early development on next generation advanced architecture bringing improved energy efficiency in our chips.
