DEVICE, SYSTEM AND METHOD FOR VERSION ROLLING WITH A BLOCKCHAIN MINING ENGINE

Abstract:

Techniques and mechanisms to facilitate Bitcoin mining operations which support version rolling. In an embodiment, Bitcoin mining circuitry comprises a first scheduler, a first digest, a second scheduler and a second digest arranged in a pipeline configuration. Hash circuitry calculates a first plurality of hashes each based on first bits of a Merkle root, and on a different respective identifier of a Bitcoin protocol version. The first scheduler generates first message schedules each based on second bits of the Merkle root, and on a different respective nonce value. In another embodiment, the first scheduler successively provides the first message schedules to the first digest, wherein, for each such providing of one of the first message schedules, the first digest, second scheduler and second digest successively generate second hashes each based on the provided one of the first message schedules, and on a different respective one of the first hashes.
