Abstract: As blockchain technology continues to evolve, decentralized markets have been progressively expanding, offering novel avenues for participation in economic activities. However, within this evolving landscape, the commenting systems of decentralized trading have not yet reached a state of comprehensive refinement. Such shortcomings have impeded participants’ trust in the platforms and have constrained the further proliferation of the decentralized trading model. An integral feature within the commenting system is anonymous evaluation, which holds significance not only for safeguarding participants’ privacy but also for playing a pivotal role in establishing reputation and credibility for trading platforms. Nonetheless, devising mechanisms to manage anonymous evaluations and establishing a trustworthy commenting system presents substantial challenges, owing to the inherent characteristics of decentralized systems that lack third-party intermediaries and regulatory bodies. Therefore, motivated by ensuring the authenticity, impartiality, and effectiveness of anonymous evaluations, along with preventing malicious evaluations and undesired behaviors like credit manipulation, we propose a robust anonymous comment management mechanism, leveraging ring signature and clustering Merkle tree for decentralized trading. Besides, we implement VeriAnon, a commenting system integrating our mechanism to enable privacy-preserving authentication of anonymous evaluators, cost-efficient management of anonymous comments, and effective verification of comment integrity and authenticity.
