Let’s say I built a blog on a decentralized platform like Blockstack. How is the data storage in a decentralized manner that I can invalidate old copies of it? Maybe I published something and then realized it was inaccurate and I ended up writing a new blog post and wanted to take the old post down. On a decentralized network how does invalidation / deletion work?
On Blockstack, you can go and delete the file: aka overwrite it with an empty file.
Since the user controls their storage, apps would have to maintain an index of files they want to censor to the larger community.
Maybe blockstack isn’t the best example since a user controls their storage. Let’s say there is a network where in order for it to be decentralized multiple users have to host the same content. How does invalidation work when you do not directly decide where the content goes, you are merely trusting the network to place your content around the network so that there is redundancy.
