Blockchains offer a secure way to immutably capture information with history and to share proof of that data without revealing the data itself. When a record is added to the blockchain, the information itself is not included. On the public blockchain, anyone can see where that entry is recorded, but no one can extract any details. Information is verified by comparing the “shape” to the one embedded in the blockchain. If the shapes are an exact match, that party has confirmed the information is the same as immutably recorded on the blockchain. 10
