@mr_stud the functionality you are asking about is addressed by IPFS. I worked on the project briefly about a year ago -- exciting stuff. IPFS&#x27;s content distribution is similar to that of a torrent. So the content gets stored across the network, with certain concentrations where people can pin it. It leaves room for giving an economic incentive for pinning it. Cost of storage shifts over to the people who care about the content rather than the people who care about it&#x27;s distribution.<p>There still would be a case where a friend&#x27;s content is unavailable because it is offline. If the friend is offline too much, one way is to have an intermediary willing to pin the content when that friend comes briefly online. It may be possible if the friend is within a large enough group, there will always be some sort of coverage.<p>Check out the IPFS website sometime. There is a white paper and demo videos.
