Hi folks !!
I was wondering whether it is really possible to create a coin where blocks will be mined by humans .. Like a puzzle will be generated for solving a block and if a person is able to solve it , he gets the reward . And as difficulty increases the puzzles gets harder and harder ..
Is it really possible ?
Sure, why not?
Provided the puzzles can be solved by humans, and not end up being bot-mined (which you can bet would be the first thing some people would be working on), it could be done.
The tricky part is in making the proof of work verifiable.
