«Hey, look at what I made! » I said triumphantly, addressing a friend of mine «It's online. Just open the link!». I was so proud of my work. After a couple evenings of frantic work, I finally put together my small project and I was ready to show it to the world. «But I don't see anything!» my first user replied, revealing a hint of skepticism «Screen's blank».

Recently I was dabbling with Quorum, an open-source suite of tools, APIs, private key managers and clients to operate a private Ethereum network. My main goal was to figure out how to build applications on top of the Ethereum blockchain and how to correctly interact with Smart Contracts.
