Les technologies blockchain combinent des innovations à des solutions informatiques existantes sur des systèmes informatiques distribués. Elles modifient de façon décisive la façon dont les organisations, même concurrentes, émettent et transfèrent en confiance des données ou des actifs numériques1 , sans passer par une structure centrale de contrôle. Il peut sembler paradoxal...

This document describes the computational models associated with blockchain and, in a second step, what is for blockchain the shutdown problem. He then asks questions about the link between shutdown problem, computation, and governability in a blockchain project. This document aims to contribute to the implementation of industrial good practices. At...

This paper discusses several areas in the real estate and mortgage industries that a blockchain could be applied to and grow from. Blockchain is a distributed ledger technology that contains a ledger recording transactions hosted on the platform of tokenized assets, which smart contracts govern using transaction protocols. After interviewing...

Milk discovery and processing enabled human settling and thriving in various settings. The discovery of cheese led to the production of whey as dairy by-product. Although it can find application in food, beverages, personal care products, pharmaceuticals and medical treatment, cheese whey is a massive dairying residue world-wide (154 Mm3·y-1)...

For blockchain governance, data is an asset, and the time parameter is strategic and sensitive. This document aims to explore this issue for blockchain. It analyses the issues related to two properties associated with the parameter time : the ability to measure time (timestamp), and the guarantee of the ordering...

White supremacy begins and ends with Columbus. Cancel Columbus. Cancel white supremacy. Imagine a world Where human beings Treat human beings Like human beings Why is that so hard to imagine?

Conventional sociology tends to reproduce rather than resolve social injustice. Rather than perpetuating that odious tradition, in this article the author proposes a remedy for racism. Sociologists often sneer at “activist” science of this nature. However, scientists in other fields tend to agree with Karl Popper’s (1999) conviction that good...

Coffee is one of the most popular beverages in the world. It is cultivated in about 70 countries in South America, Africa, and Asia and more than 8m tons of coffee are produced annually. The two most successful species of coffee are the Arabica and the Robusta. In the US...

Polar codes, recently accepted for adoption in 5G standard due to their excellent performance at a very low complexity compared to other competitive schemes in the literature, are deemed to be a strong candidate for the Internet of Things (IoT) applications as well due to meeting their requirements. However, since...

Ensuring the security of the Internet of Things (IoT) is deemed as one of the most critical challenges and needs that have to be addressed in order to guarantee the successful deployment of IoT in emerging technologies like 5G. In an effort to address this challenge, in this work, an...
