To get an idea you can search for blockchain on Google Scholar. There is plenty to be done. Some naive questions could be... How to scale them, how to increase privacy, what are the right incentive structures, what happens if you change those structures, how can you reduce the size of the chain while still keeping the chain secure, what kind of attacks are possible and how do you mitigate or prevent them and so on.
- FabHK 5y agoAnswer to 95% of the above questions: have a trusted central authority and permissioning. Then you can trivially scale, increase privacy, keep it small and secure, and prevent attacks.
- cinntaile 5y agoThat's why they're not researching how to do it when you have a trusted central authority and permissioning. Come on man, this kind of comment doesn't add value to the discussion at all. You can do better than this.
- FabHK 5y agoYou'd be surprised, though, how often people forget that. Working without a trusted central authority and permissioning is extraordinarily expensive and wasteful. Think about it, the actual useful compute power of Bitcoin (or Ethereum) is about what one average computer can do. But because of massive duplication (can't trust the other one) plus PoW, you need around 100,000,000 times the compute power. The real question then is when or under what circumstances it is worth it, and that question is not being asked enough.
