POWER CONSUMPTION PERCEPTION POW CONSENSUS MECHANISM FOR BLOCK CHAIN

摘要

A power consumption perception PoW consensus mechanism for a block chain, comprising the following process steps: (1) in a Bitcoin system, all nodes compete with each other on the basis of respective computer computing power to jointly solve an SHA math problem that is complex to solve but easy to verify, and a node which solves the problem at the fastest speed obtains a block accounting right and Bitcoin award automatically generated by the system; (2) interconnecting physical servers located at different geographical locations by using a WDM mesh network to form a block chain infrastructure network, generating power consumption in response to a block chain request, integrating block chain nodes on light load servers to fewer physical servers, directing communication requirements to fewer links, and turning off unnecessary servers and nodes. By using the power consumption perception PoW consensus mechanism, resource potential of the infrastructure network can be further exploited while the performance of the block chain is improved; in addition, power consumption can be perceived, so as to reduce carbon emission and greenhouse effect.
