A new report by Prof. Yuichi Ikeda, titled “Can Price Surges in Cryptoassets Be Predicted? — A Study on Early Transaction Signals Before Market Movements”, has been published on the SBI Financial and Economic Research Institute website.  Read the report:   https://sbiferi.co.jp/report/20250625_3.html

In June 2025, Professor Yuichi Ikeda of the Graduate School of Advanced Integrated Studies in Human Survivability at Kyoto University was selected as a recipient of the UBRI Connect 2025 Educator Award, presented by Ripple’s University Blockchain Research Initiative (UBRI). This award recognizes educators who have made exceptional contributions to teaching and research at the intersection of blockchain technology and society. Professor Ikeda has developed an AI-enhanced DAO system to detect anomalies in crypto markets, incorporating advanced techniques such as Boltzmann machines and persistent homology. He also contributed to the EDISON-X blockchain energy platform by implementing machine learning automation, and built a decentralized identity system using smart contracts on XPRL. In addition to these efforts, he leads a project on crypto network analysis at the Research Institute of Economy, Trade and Industry (RIETI), and conducts interdisciplinary blockchain research at Kyoto University. He organizes the annual Blockchain Conference Kyoto (BCK), teaches a graduate-level course on blockchain economics, and mentors students engaged in related fields, making notable contributions in both research and education. Last year’s award winners (2024) can be viewed in the “2024 Award Winners” section of the official UBRI Connect website: https://www.ubriconnect.com/ The 2025 award winners will also be published on the same site in the near future.

Professor Yuichi Ikeda was a panelist at "UBRI Connect at Apex 2025" on Wednesday, June 11, 2025. For more information on the event, please click here . Please see the “Detailed” section on this page for the agenda.Professor Ikeda's panel session is listed under the program on Wednesday, June 11 at 4:30 PM, titled “AI in Financial Services: Who Controls It, Who Benefits, and Who Sets the Rules.”

On Tuesday, April 21st, the Blockchain Research Center/Network Society Study Group will host the 2st Social Innovation Seminar, 2025. The title is " Unraveling the Complexity of Cryptoasset Ecosystems " and the speaker will be Dr. Bernhard Haslhofer who co-leads the digital currency ecosystem research group at the Complex Systems Science Hub in Vienna.   Previously, he served as a thematic coordinator in the Data Science & Artificial Intelligence research group at the Austrian Institute of Technology (AIT), a Marie Curie Fellow at Cornell Information Science, and an assistant professor at the University of Vienna. Cryptoassets have evolved into a complex, global ecosystem where diverse actors conduct financial transactions using various types of digital assets. The market has grown significantly, and the emergence of Decentralized Finance (DeFi) around 2021 marked a pivotal shift in the cryptoasset landscape. examined, there is an increasing need for computational methods to analyze these ecosystems, supporting law enforcement, regulators, compliance efforts, and researchers across disciplines seeking to understand their socio-economic dynamics and broader implications. This talk will introduce the field of cryptoasset analytics, showcase computational methods and algorithms we have developed to study complex cryptoasset ecosystems across multiple technical layers, and provide insights into our ongoing research in this evolving domain.

On Tuesday, April 1st, the Blockchain Research Center/Network Society Study Group will host the 1st Social Innovation Seminar, 2025. The title is "Systemic Risk and Shock Propagation in Firm-level Supply Networks" and the speaker will be Dr. Christian Diem from INET Oxford and the Smith School for Enterprise and the Environment. The vulnerability of supply chains to recent global crises and natural disasters can result in significant economic costs and financial losses for companies and banks, and can cause severe supply shortages of goods. We discuss systemic risk and shock propagation in supply chain networks.
