I don't know about "repulsive", but currently it seems like blockchain burns a lot of electricity (=> CO2 emissions) for very little purpose. For that reason I currently stay away.

Perhaps at some point someone will design a distributed blockchain system that (a) isn't a total power hog and (b) provides some sort of human curation that I can do so that I'm not hosting someone else's NSFL picture collection.

Until then I'll just watch from the bleachers.

there are plenty low power proof of stake blockchains. they are becoming a lot more popular for scalability and efficiency reasons. currently everyone is on the hunt for the next proof of stake 'ethereum killer' with a lot of speculative investment. ethereum itself is planning a migration to proof of stake.

right now, i'm not personally a huge fan of proof of stake because of the 'nothing at stake' problem, but one will eventually take off.
