1. A method for providing power consumption data for a distributed system in blockchains by a processor, comprising:
determining, by one or more blockchain nodes currently executing a proof of work on one of a plurality of transactions upon executing a cryptographic operation in a blockchain network, an estimation of an entropy for the proof of work as a function of a complexity of the proof of work in bits;
determining, by the or more blockchain nodes, an average number of operations to perform the proof of work based on a ratio of throughput of a respective node of the one or more blockchain nodes compared to a total network throughput of the blockchain network;
computing, by the one or more blockchain nodes, an average energy of the respective node using the estimation of the entropy, the estimation of the average number of operations, and a temperature sink of the respective node;
estimating, by the one or more blockchain nodes, energy consumption of the respective node based on the average energy of the respective node and a current block rate of the blockchain network, and
executing, by the one or more blockchain nodes, the proof of work on additional transactions of the plurality of transactions based upon the estimated energy consumption.

applying the entropy lower bound to the plurality of transactions on each of the one or more blockchain nodes; and
estimating the increase in the entropy for the one or more blockchain nodes.

5. The method of claim 1 , further including:
determining an entropy per node using a Landauer limit that establishes an entropy lower bound for an increase in the entropy by an irreversible bit operation; and
determining an average energy consumption for each of the one or more blockchain nodes using the entropy lower bound on the proof of work in the blockchain network.
