Distributed immutable ledgers, or blockchains, allow the secure digitization of evidential transactions without relying on a trusted third-party. Evidential transactions involve the exchange of any form of physical evidence, such as money, birth …

Bir önceki yazıda, Bitcoin sisteminin neden sürdürülebilir olmadığından söz etmiştim. Bu yazıda, bir başka önemli husus olan adalet konusuna değineceğim ve Bitcoin sisteminin neden adil olmadığını aktarmaya çalışacağım.

I attended to IOTA Meetup France organized in Paris held at the Microsoft building a few days ago (14 December 2017). Below, I will try to convey my impressions about what the IOTA presenters talked about in this event:

Interested cryptocurrency users have already realized that sometimes the values graphs of cryptocurrencies look quite similar. For example, such a phenomenon has been noticed between Bitcoin, Ethereum and Litecoin and reported on StackExchange.

Les systemes distribues permettent de realiser les echanges des donnees d'une application deployee a l'echelle d'une ville ou a l'echelle mondiale, tout en preservant la confiance numerique.

Context Blockchain technologies are suited to enact a large number of interactions among system users without the need of a central authority. Trust among users is built in a decentralized manner thanks to a distributed protocol permanently running among geographically distributed nodes.

Context The management of the flow of assets (goods, physical components, digital data and assets, etc.) in a distributed and efficient manner while managing the trust between the organizations (suppliers, integrators, service providers, resellers, clients, customers, users, etc.

This tutorial is aimed at those who are eager to learn blockchains and smart contract but totally new to Ethereum and has little knowledge about blockchains. It provides a set of examples where for each example it is explained, step by step, how to design, develop and use it.
