Abstract:
Systems, methods, and apparatuses are described wherein a block chain or block chain network can be created and the mining of new blocks can be limited to certain actors holding a specific set of private keys and verified by the corresponding public keys accessible to consumers interested in validating the block chain. These keys are stored in software or on specific hardware devices designed to not reveal the private key. Only blocks mined using those keys are acceptable on the block chain. The signing of the blocks in the particular block chain is integrated in such a fashion as to be integral to the proof of work for the block chain.

Claim (Index 1):
A method for mining blocks in a block chain, the method comprising the steps of:\n (a) finding by a bookkeeping device a previous block in the block chain; (b) calculating by the bookkeeping device a payload for a new block in the block chain; (c) updating by the bookkeeping device a plurality of bookkeeping fields that are stored in the new block; (d) updating by the bookkeeping device a nonce value; (e) receiving from a signing device in the bookkeeping device a digital signature for the new block as a new bookkeeping field; (f) hashing by the bookkeeping device the new block; (g) determining by the bookkeeping device if the hash is rare enough; and (h) when the hash is rare enough, broadcasting by the bookkeeping device the new block to a block chain network.
