Understanding Ethereum ?!

Ethereum is considered the most promising blockchain outside Bitcoin. Its creators speak of it as the "first true global computer", which makes it possible to build on its platform decentralized applications.

Stephan Tual, former spokesperson for the platform and founder of the startup Slock.it, defined the role of Ethereum in an interview with Time in 2014: "Ethereum aims to build a Web where intermediaries between customers and services they are looking for no longer exist. If I want, for example, to enter into a digital contract with you, why would I need a lawyer for that? Let us agree on the terms of this contract. In the Ethereum infrastructure, it is not modifiable or falsifiable since its security is guaranteed by a cryptographic protocol. We save on lawyer fees while gaining security. This idea can be applied to other services such as social networks, crowdfunding sites, eBay, Airbnb ... We solve several current problems of the Web. "
