Look at Arweave. https://www.arweave.org/ https://www.arweave.org/ Taken from their site: arweave is a global, permanent hard drive built on two novel technologies: the blockweave, a derivative of the blockchain, and proof of access, a custom incentivized proof of work algorithm. These innovations provide truly permanent data storage for the very first time and at a massive scale. Essentially it is putting files on the blockchain in a permanent manner. There are some podcasts out there where the founder talks about the details.
