PoW is not required to have a blockchain. What you need is any consensus algorithm. For example you could use Proof of Stake.
- ufo 9y agoThe impression I got last time I studies about proof of stake is that it is still an open problem. You need to find ways to stop people from gaming the system by computing multiple parallel histories (which would devolve the system into proof-of-work) and the only ways to do this that I am aware of are at least partially reliant on agreeing on a central authority.
