I see your edit so let me address that also. Yes, our use for the blockchain is to provide verifiable information to untrusted parties. Instead of information about transactions and balances, it's information about text edits. In a simple scenario, every edit you make to a document is recorded individually and hashed with the hash of the previous edit. This forms the chain. The chain itself can be stored anywhere. It's useless if you don't have the document. But if you do have the document or any fragment, you can instantly tell what version you have and if it has any differences from the original -- without seeing the original.
