This is not a top priority in my opinion right now. We can go ahead with a normal design and maintain a centralized database in the KDE servers. Once we have a working prototype we can come back and try to use blockchain in the app. >> An application like this comes in handy when a group of people need to >> manage their regular expenses, and we thought it might be a good idea >> to have something similar in KDE.
