Abstract
A method and apparatus provides a blockchain that includes one or more blocks that contain a cryptographic binding of a signature-verification public key and/or a data encryption public key to the identity of the holder of the corresponding private key. The binding is performed by one or more key binding entities, referred to herein as a blockchain identity binder. Originators and recipients use the identity binding data to secure block chain transactions.
