I was always wondering about this. From the start it seemed like "blockchain" could be easily replaced by a few trusted validators run by independent organizations, the same way certificate transparency logs are operated, for example. The value in Bitcoin and proof-of-work was that everyone could contribute to the security of the log. As soon as mining pools appeared, and now even more with proof-of-stake, we are back with a few parties being the trusted validators. The fact that they get their powers from on-chain tokens rather than community decision... is it really a good thing?
