Problems that can be solved with blockchain must have a certain value if they get solved, and since blockchains are a good value store, perhaps we could make a blockchain where blocks are mined based on solving blockchain related issues, and the miners who solve these issues then get the rewards. I’m a bit fuzzy on the technical details, so perhaps the first draft can use written contracts and fiat exchanges as placeholder for the blockchain tech, and focus on problems that can be solved using the same. But there’s definitely a great startup idea here if only we can get the billions in investment needed to make this dream a reality!
