Registration: Entrance is free for all

13.00-13.10: Bart van der Sloot - Welcome



13.10-13.30: Mireille Hildebrandt (Vrije Universiteit Brussel, Radboud Universiteit)


Mireille Hildebrandt will briefly discuss a set of myths that are often framed as ‘innate' properties of blockchain applications, notably the idea of an egalitarian consensus mechanism, of ‘innate’ immutability and irreversibility, the idea of trestles computing and the notions of publicness and transparency. She will then argue that for each concrete application a triple test must be conducted: (1) which problem is solved (compared to status quo and alternative solutions), (2) which problem is not solved (idem), and (3) which problem is created (idem). She will conclude with a brief discussion of design-based regulation and ‘legal protection by design’.


13.30-13.50 Discussion



13.50-14.10: Jaap-Henk Hoepman (Radboud Universiteit )


"The blockchain dissected" What are blockchains/distributed ledgers? How do they work? And what are their (claimed) properties? We will dissect the blockchain and address these questions. We will pinpoint certain fundamental pitfalls surrounding blockchain technologies, and ask ourself the question: is there any use for them?


14.10-14.30: Discussion



14.30-14.45: Break



14.45-15.05: Maarten Everts (TNO)


Smart contract says No - Smart contracts are hyped to take on the role of incorruptible, trustable third parties. However, the “immutability” that makes this possible also means that mistakes in smart contracts can have a significant impact. How are smart contracts different from “normal” software? What are the dangers? Is it possible to keep the human in the loop?


15.05-15.25: Discussion



15.25-15.45: Michelle Finck (Max Planck Institute for Innovation and Competition)


The paper examines smart contracts from the perspective of Article 22 GPDR. It suggests that smart contracts likely qualify as a form of solely automated data processing and are hence caught by the qualified prohibition under Article 22 GDPR. It then evaluates the consequences flowing from that state of affairs and suggests that current efforts of sophisticating these tools may have a side-effect of GDPR compliance'.


15.45-16.05: Discussion



16.05-16.20: Break



16.20-16.40: Maurice Schellekens (Tilburg University)


‘Asking the right question(s) about blockchain: does the law actually regulate technology?’


16.40-17.00: Discussion



17.00-17.30: General debate
