First, it is discussed theoretically what a blockchain is, how this technology is built, and some tools for developing decentralized applications. This theoretical part is to put the reader in context and better understand the practical case. This practical case is a decentralized application programmed by the author of this document to show how important this technology can be and how it can modify how a business is man-aged now. The main goal is to show that blockchain technology is beyond supporting cryptocurrencies and NFTs are beyond art speculation
