International Blockchain School 2022

24th-28th of January 2022


The International Blockchain School (Winter Edition) will be held at IT University of Copenhagen on the 24th-28th of January 2022. The International Blockchain School is an initiative of the European Blockchain Center and run jointly for the fifth year by faculty members from IT University of Copenhagen, Copenhagen Business School, Copenhagen University, and University of the Faroe Islands. The International Blockchain School would not be possible without the generous support of our partners.

Aims and Objectives

Blockchain and Distributed Ledger Technology (DLT) in general form the foundation of new decentralized business models. Start-ups, large organizations, and governments alike work intensely on blockchain-based innovation, making the technology one of the most promising drivers of innovation since the emergence of the Internet. However, the design and implementation of blockchain-based systems requires know-how in several areas, as well as mindful consideration of larger economic and societal issues. These objectives provide the starting point for this Blockchain School.

In this Fifth International Blockchain School organized by the European Blockchain Center, we will focus on educating PhD and master students in blockchain technology to develop solutions within different industries. The participants will learn how blockchain technology is disrupting existing business models and will gain insights into paradigmatic changes from economic, organizational, and computer science viewpoints. They will learn to analyze existing business processes and how blockchain-based solutions have the potential to disrupt them. In so doing, they will be enabled to co-create new blockchain-based systems, taking into consideration both cryptographic and economic aspects.

Within the International Blockchain School, participants will learn how to set up a development environment and how to work with proven platforms such as Ethereum, Algorand, NEO and others. They will be able to design and implement their own smart contracts and will code their own decentralized applications.

Once basic blockchain elements have been introduced, participants will work on their own blockchain development projects, supported by the participating industry partners. The outcomes will be functioning demonstrators, as well as a written documentation and reports that illustrate the business process or mechanism realized in a blockchain implementation and how, in so doing, a real-world challenge is addressed.

The theme of the Fifth International Blockchain School is Sustainable Decentralized Finance and the course will be held over five days. There will be three parallel tracks in which the students will work:

  1. In track one (explorer track), students with basic prior blockchain experience will work together with case organisations from industry and public sector on developing blockchain prototypes in a hackathon.
  2. Track two (exploiter track) is geared towards students with advanced knowledge around blockchain prototyping to work with organisations which already have prototypes developed. In this hackathon, demonstrators are further improved or designed anew.
  3. In track three technical issues in existing Blockchain / DLT systems are discussed and potential solutions are developed. This is a makerthon, where not necessarily code is written, but where potential solutions are developed conceptually.

Project Description

In 2017, the Peoples Bank of China stated that “the future of money is crypto” and we aim to shed light on that future in our cross-disciplinary International Blockchain School together. Increasingly, start-ups in the Fintech, TechFin and DeFi sector focus on DLT-based innovations to provide new financial services to private or corporate clients. Those innovations primarily promise better and more affordable solutions while guaranteeing transparency, high execution quality, and auditability. New payment services for international money transfer, better access to capital markets for SMEs, programmable solutions to settle transactions autonomously, intelligent wallets that act on behave of their owners, decentralized exchanges that allow nearly instant trading, new types of on-ledger data analytics, smarter integration of seamless taxation, new shared ownership models of digital or digitized assets, and quantum computing secure DeFi solutions are just some examples where DLT systems in combination with a tokenization of the economy are not just changing existing financial business models, but the financial market itself. The aim of this Blockchain School is to develop innovative ideas on sustainable decentralized finance. Sustainable DeFi does not only generate better and more sophisticated financial services in networked business models, but is doing so in an eco-friendly, and durable way. The longevity of distributed business models is dependent on ecologic and ecology sustainability. Together with our partnering organizations, we will develop use cases and challenges that will be the base for the hackathon and makathon, where students in close cooperation with the case-giving organizations will create suggestions for sustainable decentralized finance solutions.

Academic Credits

An amount of 6 ECTS will be provided to PhD students who successfully pass the exam.


Participants will present their blockchain solutions at the end of the International Blockchain School and defend these. In addition, they will produce 15 pages of report after the course and/or write a paper that is to be submitted to an academic outlet, such as conference or journal, coached by the International Blockchain School organizers. The presentation, report as well as the working paper are mandatory deliverables and after they have been assessed at a satisfactory level, the ECTS points will be granted and a certificate issued. Independently, all participants will receive a certificate that they have participated in the International Blockchain School.


The number of participants in the International Blockchain School is limited and we accept applications on an ongoing basis. Interested students are encouraged to apply early.


In contrast to the four successful International Blockchain Schools in 2016 to 2019, this year we will lift it to the next level by establishing three parallel tracks on Wednesday and Thursday:

  1. Explorer: this track will be the continuation the successful format from previous years. In addition to this, students will work together with case organisations from industry and public sector on developing blockchain prototypes in a hackathon.
  2. Exploiter: this track will offer the opportunity for students with prior experience around blockchain prototyping to work with organisations which have already prototypes developed. The intention in the included hackathon is to further improve demonstrators, or design them anew, to meet the more advanced requirements and level of know-how among participating students as well as organisations.
  3. Next Tech: this track is the protocol track where technical issues in existing blockchain / DLT systems are discussed and potential solutions are developed. This track will include a makerthon, where not necessarily code is written, but where potential solutions are developed conceptually.

All students will be encouraged to further improve their work in form of academic papers coached by the blockchain school organisers.
