Hey PH 👋
SealZero started from reading the PETS 2025 paper “VIMz: Private Proofs of Image Manipulation using Folding-based zkSNARKs” by Stefan Dziembowski, Shahriar Ebrahimi, and Parisa Hassanizadeh. I was curious how these ideas could move from theory into something actually usable.
Working daily with sensitive HR documents, I know how hard it is to share redacted files while still proving their authenticity. SealZero explores that gap: mask sensitive parts, share the result, and attach a verifiable cryptographic proof — generated fully client-side.
Would love your feedback from privacy, security, and dev tooling folks! 🔐✨
