DeepVault is an information store that is held within the blockchain meaning that the data is immutable, forever! More specifically, DeepVault allows Onion members to store file validation credentials (hashes of files) within the blockchain. This has obvious benefits as it allows users to verify a file's integrity over time. Therefore, if the hash of the file changes, then the file has been altered or corrupted.
So, is that alreayd implemented? it looks just another plan for the future roadmap of deeponion. But if you are hoping this torcoin brother goes to the moon and then you can try to ask the developer to erase the pre-mined coin.
