Blockchain technology has been in the news recently, mainly because it aims to provide an alternative model of network computing platform that is decentralised and trustless, the underlying properties that made Bitcoin popular. One open source crowd-funded platform that has gained a lot of attention in the industry and media is Ethereum (www.ethereum.org). Ethereum claims to overcome several deficiencies of the earlier Bitcoin technology so that it can be used for purposes other than just transferring currency. IBM and Samsung demonstrated (https://www.youtube.com/watch?v=U1XOPIqyP7A ) how smart Internet of Things (IoT) devices based on decentralised platforms such as Ethereum can become autonomous and perform transactions by themselves. In this talk Konstantin Kudryavtsev, Head of Technical Relations from Ethereum will present an overview of Ethereum’s ecosystem, delve deeper into demystifying the platform with regards to what works and what doesn’t and finally provide some guidance on using ‘smart contracts’.
