The International Blockchain School will be held at IT University of Copenhagen on the 14th-18th of August, 2023. The International Blockchain School is an initiative of the European Blockchain Center and run jointly for the sixth year by faculty members from IT University of Copenhagen, Copenhagen Business School, and Copenhagen University. The International Blockchain School would not be possible without the generous support of Our Partners. The 6th Blockchain School will bring academia, industry, and the public sector together to work on Decentralized Finance (DeFi) systems with special focus on Regenerative Finance (ReFi). PhD and master students from different disciplines and different regions are welcomed to Copenhagen to co-create new ideas and develop solutions in close cooperation with partners from Copenhagen FinTech Lab, as well as industry partners and regulators from all over Europe.
