Abstract

A method for efficiently storing and verifying records is disclosed. The method may comprise receiving a first hash of first interaction data and determining an interaction identifier associated with the first hash, then storing the first hash in a database along with the interaction identifier and determining a root hash of a hash tree. In addition, the method may also comprise providing the root hash of the hash tree to a public blockchain. Embodiments of the invention also allow users to easily present records to a third party or inquiring entity. Furthermore, interactions may be processed more quickly than previous blockchain methods that publish to a block during each individual interaction.
