【Abstract】Blockchain has decentralization characteristics and requires more targeted security schemes to protect user privacy. In contrast, existing signature schemes have many high-complexity operations and impose an enormous computational burden on wireless nodes. This article proposes a light-weighted identity privacy scheme for blockchain-based on edge computing. We construct linkable identity privacy and non-linkable identity privacy, which can resist collusion attacks while virtually guaranteeing blockchain nodes' identity privacy. Since edge computing offloads heavily, the proposed scheme has lower computational complexity than the existing techniques.
