I tend to ignore anything blockchain-based, because as we can see with Bitcoin if it becomes popular then after a while it also becomes centralised, because only a few people can do block solving.

When block solving is controlled by a small group, then all sorts of bad things can happen, such as false transactions, censored transactions and so on.

So I think blockchains with proof of work aren't viable as a decentralization method - or at best they're only viable for a short time period while block solving difficulty is low enough that consensus provides protection against bad actors.
