Framework Design and Theoretical Research on Abstract Account Gas Payment Mechanism

Abstract

In order to solve the limitations of externally held accounts (EOA) and contract accounts (CA), Ethereum proposed to combine the two and design an abstract account, which can both initiate transactions and execute code. The Gas payment mechanism of abstract accounts has the risk of user information leakage. In order to solve the problem of user privacy, this paper proposes to use zero-knowledge proof (ZKP) to strengthen user privacy protection, and designs a technical framework for the interaction between Dapps and abstract account wallets; in order to meet the needs of multi-circuit and high efficiency, zero-knowledge proof is combined with BLS technology, and a Gas payment scheme based on proof aggregation and BLS signature (GP-PABLS) is designed; finally, the feasibility and efficiency of the experimental test scheme are designed, which improves the privacy and friendliness of users, provides theoretical and technical guidance for the development of abstract accounts and Gas payment mechanisms, and further promotes the development and improvement of blockchain applications.
