#gridcoin launched the idea of a block-chain backed supercomputer about 4 years ago, is fully functional on CPU & GPU, has it's own block-chain rather than relying on someone else's, has over 20 currently operational major computing projects, and is almost always top 20 on CoinGecko by developer activity.

Elastic looks interesting, but most use cases have already been delivered by Gridcoin. Unfortunately commercial operators just don't want to trust unknown actors with their data processing, so open science projects is the mainstay of work on Gridcoin.
