Abstract
A system and method for ensuring digital integrity of a blockchain is presented. The blockchain is initiated with one or more digital certificates presented in one of an initial set of blocks of the blockchain. One or more of the digital certificates may subsequently be used to sign a hash of a sequence of blocks in the blockchain at regular or semi-regular intervals. If a sequence of consecutive blocks is longer than a predetermined number and does not contain a signature from one or more of the digital certificates of a hash or one or more of the blocks in the sequence, the sequence may be considered not to comprise a part of the blockchain. In other embodiments side blocks may be signed and added to the blockchain.
