"DeepVault is a blockchain notary that allows you to store file validation credentials (hashes of files) within the blockchain.
I'm not familiar with their coin. When you say blockchain, is it Bitcoin's blockchain, or their own blockchain?
Because, here is what they state on their website:
The SHA256 hash got locally from the client's program for a specific archive is transmitted to the DeepVault server. A bitcoin exchange including a call of the 'OP_RETURN' type is done with a specific end goal to post this hash on the blockchain. What might as well be called the ASCII content 'DV##' (proportional to hex '57540414d50242353') is likewise included toward the start of the hash. The 'OP_RETURN' sort of exchange has been provisioned by the bitcoin designers group keeping in mind the end goal to permit the likelihood of posting information on the exchanges incorporated into the blockchain open record. Quote from:
https://deepvaultonline.com/You can use OP_RETURN on Bitcoin's blockchain directly to store any data you like, you don't really need an intermediary to do that.
In any case, I like their concept. Hashing, combined with the immutability of the blockchain, can be used as a immutable proof of ownership.
