This workshop is an intensive and fast-paced training course that will help learners quickly grasp the principles behind the æternity architecture as well as learn how to build basic smart contracts on the platform through Sophia. In the second part of this crash course, participants will also experience first-hand how to integrate æternity features into their contracts. The workshop covers the functional mark-up language (ML) Sophia, built-ins, functional programming, first-class objects, oracles and state channels among others. We also tackle real-life use cases to help participants gain an understanding of its potential implications in solving global problems – both for business and social impact.
