An Evaluation of Power Consumption Gain and Security of Flexible Green Pool Mining in Public Blockchain Systems

This paper proposes a variant of the recently reported pool mining approach and provides reduction in energy that is consumed by blockchain consensus protocol. The novelty proposed architecture lies employment an innovative cryptographic puzzle based on stream ciphering. enables flexibility setting difficulty parameter protocol, allows for separation memory resources are required solving. high resistance against following malicious activities miners public systems: (i) submission fake work fictitious computation results; (ii) some well-known attacks target incentive mechanism. We experimentally evaluate power consumption protocol compare it with traditional proof-of-work hashing. obtained results point out gain compared types.
