Books have a great place in our lives. The library system will also change in the developing world. I thought about how this process would be on BlockChain. And I came to this conclusion:
An application where you pay as much as the number of books you read.
You can find the link of the loom video and Patika at the bottom.
- Create books with book name, author name, genre, description etc. fields. Then may modify, inactivate them.
- EDetermines and creates membership types.
- Creates membership, buy subscription types so buys the right to read books. Also may checks/list books, account details.
