Blockchain technology has a lot of advantage so why not take it? Russia even reported that they're going to implement a sort of blockchain based voting so that's a good start isn't it?
Maybe that's one use case and then there will be others as well. Even companies now are adopting to this technology specially in the logistics sectors because of the amount of data that they need to processed and I'm sure blockchain will be a big help specially that data can't be manipulated or altered ensuring the product conforming to industry standards.
Blockchain technology if fully deployed is absolutely a way out in term of curbing election rigging, Russia had already adopted it for voting process also its very useful in chain supplies, medicine and other valuable sectors of the economy the OP is laying more emphasis on the usefulness of this technology on mainly cryptocurrencies not mindful of the fact that this technology goes beyond using it to create shitcoins.
