What we call “smart contracts” are actually computer programs which enable us to automate a number of operations and transactions that are sometimes very complex. Therefore, these programs can automatically complete the terms of a contract without any human intervention. They can be developed on blockchain platforms, such as the Ethereum platform, which are able to keep track of each transaction in a tamper-proof and secure manner. The object of this workshop is to consider the opportunities that this technology opens up for lawyers and their clients, as well as the legal issues that it will raise.
