Blockchain For Identity Management: It’s Years Away:
"Rather than lodging a virtual currency transfer, it's possible to embed identity information in the ledger. The broad vision is a blockchain could be a tamper-proof reference point to verify personal data without having to expose the actual data to a service provider.
