STARK Two “S-two”, the new ZK prover by StarkWare, allows end users to generate cryptographic proofs directly on their own devices, enabling a new level of local privacy and reducing reliance on third-party infrastructure

Quotes that support claims

With S-two, proofs will be generated locally on the client side and submitted directly to Ethereum, potentially making every browser a self-sovereign proving node and reducing liveness risks from single-hosted clusters.

the new ZK prover allows users to generate complex cryptographic proofs from the client side. This means users can generate ZK-proofs directly on their devices instead of relying on a server or cloud infrastructure
