The Jengascoin blockchain has many potential uses in terms of digital licensing. The example that we will demonstrate today is using the Jengascoin Blockchain to power a platform agnostic anti-cheat solution for video games.
In our example, a Business provides a video game anti cheat solution to multiple clients. The anti cheat is licensed to clients using the Jengascoin blockchain. The anti cheat asks the users wallet for a signed message which confirms ownership of a specific NFT token, representing a license to the video game. The wallet replies with a message and its public_key address associated with the address which holds their NFT. The anti cheat can use openssl libraries to verify the signed message and grant access to the program.

When the license is valid, the end user is taken to the login screen.
When the license NFT is not found (the license is invalid) the user gets an error.
