Investigation of upgraded smart contract based-on Ethereum platform

Abstract

This thesis thoroughly explores upgradeable smart contracts and their deployment pat- terns using the well-known OpenZeppelin technique. As blockchain technologies become more prevalent in our digital world, it is crucial to understand the various implications of using upgradeable smart contract patterns, mainly from security, efficiency, and eco- nomic standpoints. Our work marks a significant academic milestone with its dual contributions: an in- depth review of upgradeable smart contract patterns underpinned by OpenZeppelin, and the development and thorough evaluation of a novel Risk Model. We provide a comprehensive study focusing on the effectiveness of these upgradeable techniques, evaluating their merits of security, efficiency, and economy. The Risk Model, meanwhile, represents a robust predictive model to identify potential risks bound to upgradeable smart contracts. We have identified the risk based on several critical factors, including average block time, mempool’s average pending time, and the gas price proposed by the transaction caller. In conclusion, the way for significant improvements in our understanding of upgrade- able smart contracts, setting a robust foundation for future academic explorations and practical blockchain applications.
