Title: Computer implemented systems and methods
Inventor: BRENDAN LEE
IPC: G06F16/27
Filed: 2022-02-07
Abstract: The invention resides in at least one of a mining system, node and a device, or method of operation thereof, that calculate a proof-of-work (PoW) required for establishing the next block in a blockchain. The invention uses a packet of PoW seed data e.g. a mining candidate derived from a block template and determines the status of external variables, including a calculation of the cost and/or difficulty to calculate the PoW for the PoW seed data. Calculation of the PoW is allocated by determining if the cost of calculating the PoW is less than the reward, or part thereof, of determining a PoW for the block template. Operational efficiency is improved leading to lower levels of computational cost and lower energy consumption. Aspects and examples herein support the modularisation of the calculation of a PoW for a blockchain network in order to achieve maximum performance efficiency based on the variables, including the resources available.
