Sure, but PoW is (by design) computationally expensive, so any blockchain solution has the burden of showing why it's sufficiently better than the alternative to merit the extra cost.
- Scarblac 9y agoAnother problem is that if your nice blockchain has N computers in it, someone can go to AWS and add N+1 and take over your network. You basically have to blow more money on PoW than the network is worth _constantly_. Or you can have a "private blockchain", which defeats the purpose entirely.
