Privacy-Preserving Content Governance: A Comprehensive Survey on zk-Promises and Stateful Anonymous Accountability

Abstract

There is a natural contradiction between anonymous expression and obeying rules, which is a big problem for traditional content management methods, because traditional methods often sacrifice user privacy in order to control violations. This paper systematically reviews zk-Promises, which is a new architecture of “anonymous status callback+zero knowledge verification”, and it can realize accountability anonymity. We don’t simply pile up technologies, but build a complete knowledge system to carefully analyze how this framework realizes stateful management and asynchronous accountability. By evaluating the core cryptography mechanism and comparing it with other privacy enhancement technologies, this study defines the technical application scope of the current solution. Our analysis found several key research gaps, including the adaptability of native mobile devices, the reliability of decentralized trust, and the interoperability between cross-border rules. Finally, we propose hardware accelerated collaboration and adaptive batch processing algorithms as the key directions to overcome the existing bottlenecks. This survey aims to provide guidance for designing scalable and privacy-preserving management systems, so as to bridge the gap between cryptography theory and large-scale real-time deployment in digital communities.
