Blockchain Kaigi 2025 (BCK25)

December 4-6, 2025, IIT Bombay, India.

The International Workshop “Blockchain Kaigi” (BCK) (会議, kaigi: Meeting, Conference) aims to bring together researchers and practitioners from diverse scientific and technological disciplines. BCK has established itself as a dynamic academic venue where forward-thinking researchers can share innovative ideas in the field of blockchain research. For this year’s iteration, BCK will be held by the Indian Institute of Technology Bombay (IIT Bombay).

The Evolution of the Blockchain Kaigi International Workshops

On February 17th – 18th, 2021, the international workshop “Blockchain in Kyoto 2021 (BCK21)” was hosted at Kyoto University, Japan. This event drew participants from around the globe, fostering a vibrant exchange of knowledge and ideas within the blockchain community. Continuing this tradition, the next instalment, “BCK22: Blockchain Kaigi 2022,” took place on August 4th – 5th, 2022, at Tohoku University, Japan. It maintained the legacy of its predecessor by uniting a diverse group of forward-thinking researchers and practitioners who shared their latest findings and innovative solutions in blockchain technology. The “BCK23: Blockchain Kaigi 2023” session was held on October 28th -29th, 2023 at RIKEN’s Kobe Campus (Kobe City), Japan. The recent edition of this kaigi was held at University of Zurich between September 12 and 13 as “BCK24: Blockchain Kaigi 2024”.

Building on this rich tradition of Blockchain Kaigi, we invite you to join us at IIT Bombay, where this year’s Blockchain Kaigi (BCK25) will be held between December 4 and 6. BCK25 will continue to serve as a venue where experts from scientific and technological disciplines can discuss, collaborate, and advance the field of blockchain research. Authors are invited to submit both theoretical and applied papers that contribute to the broad spectrum of blockchain studies.
