Blockchain Kaigi 2024

September 12-13, 2024, Zurich, Switzerland

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 University of Zurich.

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 recent session, “BCK23: Blockchain Kaigi 2023” was held on October 28th -29th, 2023 at RIKEN’s Kobe Campus (Kobe City), Japan. The upcoming iteration is Blockchain Kaigi 2024, scheduled for September 2024 in Zurich, Switzerland. This iteration will continue to serve as a dynamic academic venue where experts from various scientific and technological disciplines can 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.
