DataSet: Empirical study of the smart contract evolution based standard upgradability methods used in Blockchain

This dataset provides information on the metrics of the cost, size, complexity, and security collected from a list of 18 smart contract projects running on Ethereum, including 157 different versions. This dataset was used to analyze the smart contract evolution carried out in our study "Smart contract evolution: Empirical study of the smart contract evolution based standard upgradability methods used in Blockchain".
