On-device proofs refer to cryptographic proofs generated directly on a user’s local device, such as a smartphone or computer, rather than relying on external servers or centralized entities. This approach enhances user privacy and security by keeping sensitive data localized during the proof generation process. It enables verifiable computations without exposing private information. This technology supports self-sovereign identity and confidential transactions.
Context
On-device proofs are a significant area of research and development for privacy-centric decentralized applications and digital identity solutions. Discussions often focus on optimizing computational efficiency for resource-constrained devices and standardizing proof formats. Future advancements aim to make these proofs a standard feature in mobile cryptocurrency wallets and secure personal data management systems.
This research introduces the first sublinear-space zero-knowledge prover, transforming proof generation into a tree evaluation problem to unlock on-device verifiable computation.
