Blockchain is a groundbreaking technology. It’s already disrupting the banking and insurance industries and has the potential to revolutionize current political and social systems. It has many implementations and applications, like Bitcoin, Ethereum, Hyperledger, Smart Contracts, Smart Laws, Distributed Apps (DApps) etc. In essence, it’s about removing the trusted authorities and giving power to the peers or people.

I can highly recommend the following three courses, which give a very well structured overview of this technology:
