Right but someone has to host it though, otherwise your blockchain ceases to exist doesn't it?

- rglullis 4y agoYes and no. You certainly need to have people validating incoming blocks, and currently you need to have at least some nodes archiving all the data if you want to be able to reconstruct the whole history. But there is a lot of research going on in regards to state pruning, which would let nodes discard parts of the chain that are not interesting.
- astrange 4y agoI agree if you can find a way to delete things then it's fine. That's not exactly immutable, but it may be workable, maybe. But currently all blockchain users have to download the entire thing unless they're just accessing it through a web API, which would be "centralized" and makes them not really blockchain users.
- rglullis 4y agoNo really true for ethereum. There are "light clients" who can validate new blocks and only stores every X blocks for checkpointing.
