If you want to create a blockchain-powered application, it would be useful to know how easy or difficult this process is. In theory, developing a blockchain-based solution is not difficult because the concept itself is relatively simple, and its tools are open-source.
However, developers face many difficulties that slow down the process or sometimes make it impossible in practice. That's why you can hardly meet an IT solution that is based on the blockchain only. Usually, applications have a combination of various technologies to work properly.
