How to apply blockchaining to data?
Chainpoint is a standard for maximizing the scalability of recording data in the blockchain and generating blockchain receipts. Each receipt contains all the information needed to verify the data without relying on a trusted third party.

You can read our white paper and download a Python implementation of a Chainpoint server at http://github.com/chainpoint.

Tierion and Storj are the first to implement this new standard.
