It offers development in blockchain applications in C# code which is loved by programmers and is easier to program with than C++. This blockchain is for the business world that, I feel business that are windows based and thats like 95% of the business world will be using.
Some of the uses for this blockchain are in the medical field with medical research, product tracking and verification, data recording and management and identity management.
