Quantifying the degree of decentralization performance of miners in a blockchain-enabled IoT network. The Gini coefficient here signifies how the distribution of computing power is made among the miners, i.e., whether it is in a centralized or decentralized manner. It can be seen that as the coefficient increases, the performance worsens and is more inclined towards centralization.
