PSFQ: A Blockchain-based Privacy-preserving and Verifiable Student Feedback Questionnaire Platform
Summary: PSFQ uses size-optimized ring signatures to anonymize respondents and homomorphic encryption of answers stored on-chain for publicly verifiable SFQ aggregation. Novelty: adaptive minimal-ring signatures that minimize anonymity overhead while enabling verifiable statistics. (summarized by gpt-5-mini on Feb 09 2026)
