21st Century Learning and Teaching

Since its advent in 2009, bitcoin’s decentralized, broker-less and secure mechanism to send money across the world has steadily risen in popularity and adoption. Of equal — if not greater — importance is the blockchain, the technology that supports the cryptocurrency, the distributed ledger which enables trustless, peer-to-peer exchange of data.

Every day, new companies and organizations, including big names such as Microsoft and Tesla, take strides toward or show interest in using cryptocurrency and blockchain to support their business.

But the fame of blockchain has also given rise to two new challenges, namely that of interoperability and flexibility.

There are now more than a score of blockchain-based currencies, each optimized for different purposes, with different exchange rates, verification and consensus mechanisms, performance, distribution function, block size limit and degree of anonymity. And none of these currencies are compatible with others, making it hard for users to transfer money between them.

Si le principe de la chaîne de blocs est relativement simple, le caractère transparent et décentralisé de la technologie peut avoir des conséquences majeures.

Wieso Smart Contracts die Erwartungen enttäuschen müssen
Was Juristen seit Jahrhunderten nicht geschafft haben, wollten Blockchain-Enthusiasten per Code regeln. Doch so leicht ist das nicht, wie der DAO-Hack zeigt. Dabei hätte man aus der Rechtsgeschichte lernen können. An einer Schnittstelle zur formalisierten Streitschlichtung geht kein Weg mehr vorbei.
Schon lange träumen Juristen davon, ein Gesetz zu formulieren, dem es gelingt, alle Problemfälle dieser Welt zu erfassen. Egal, was auch passieren mag: Das Recht gibt eindeutig vor, wie die passende Lösung auszusehen hat. Diesen Traum teilt die Smart-Contract-Community.

Ein automatisierter Vertrag soll her, der keiner menschlichen Interpretation bedarf. Alle möglichen Abzweigungen sind der Blockchain schon einprogrammiert. Ein hehres Ziel - doch in der Geschichte des Vertragsrechts stets gescheitert. Auch Smart Contracts sind vor diesem Schicksal nicht gefeit.

DAOs, Hacks and the Law
“The DAO” is in the midst of an epic hack due to an exploit on the originating smart contracts. Unfortunately it may seem that their own choice of legal infrastructures may force them to honor the exploit instead of the intent.
Smart contracts meet the law
While the specifics vary from land to land, the law has a broad set of parameters that are uniform. They govern the agreements made between humans and the rules which bind them.
Curiously, the DAO, in order to show it’s adherence to a certain form of “smart” contract stated that it would be fully and exclusively bound by these blockchain smart contracts.
