People acknowledge the value of data and the benefits of data collaborations [1]. Yet, concerns about data privacy and security are increasing [2]. Especially when dealing with sensitive data, these concerns are often justified. To solve these challenges, the leaders in the field of

Until today, data-sensitive companies are unable to utilize the immense benefits of cloud computing. It is well known that cloud-computing offers many advantages, ranging from increased scalability to reduced operations and update costs. However, in the age of decentralized computation, cybersecurity and data privacy

ZoKrates is a toolbox for zkSNARKs on Ethereum. It includes an easy-to-use  domain-specific language for developers to leverage the power of  zero-knowledge proofs in their decentralized applications. Elliptic Curve Cryptography (ECC) is a powerful tool that has many  applications in the blockchain space and

Buying data is a lengthy process on its own. Finding the right vendor, type of data and passing all the regulatory and legal procedures takes time and costs money. On top of that, in practical reality, the procedure is even lengthier because it starts

Over the last centuries, humanity has tested and implemented various governance models for society and individuals. Checks and balances, separation of powers and democracy are ways of making our societies to be governed as fair as possible. It’s about not to give too

Today for most organizations it is hard to impossible to benefit from artificial intelligence (AI). Especially, when it comes to training and applying machine learning models because they require substantial investments of money, time, data and expertise. These factors are all scarce resources. Scarcity

Cryptography is the backbone of our current digital society, but how did it become so important? Interestingly, the systematic study of cryptography as a science (and perhaps as an art) started only during the past 100 years. The word cryptography is derived from the

In this blog we implement a problem that's very typical in blockchain use-cases: proving the knowledge of a pre-image for a given SHA-256 digest. We will begin demystifying this machinery by computing the SHA-256 hash of the number 5. Towards this end, we will

OverviewIn this series of posts, we will look at zero-knowledge proofs (ZKPs): a family of probabilistic protocols, first described by Goldwasser, Micali and Rackoff in 1985, which has garnered increased popularity with the rise of distributed ledger technology (DLT). We will start by introducing

Why do people protest against nuclear power? It’s clean, it’s cheap, and it doesn’t smell. Perhaps it is because of the risk attached to this source of electricity. In case of an accident the benefits are eliminated by the disastrous power
