Selecting Miners within Blockchain-based Systems Using Evolutionary Algorithms for Energy Optimisation
This addresses energy efficiency in blockchain systems, but appears incremental as it applies known optimization methods to a specific domain.
The paper tackled the problem of minimizing blockchain energy consumption by formulating miner selection as a multi-objective optimization problem balancing energy and trust, and compared different algorithms to demonstrate performance.
In this paper, we represent the problem of selecting miners within a blockchain-based system as a subset selection problem. We formulate the problem of minimising blockchain energy consumption as an optimisation problem with two conflicting objectives: energy consumption and trust. The proposed model is compared across different algorithms to demonstrate its performance.
