Privacy projectMiden: Client-side proving chain (upcoming). Technology: zero-knowledge proofs.
Miden spun out of Polygon with 25 million dollars behind a genuinely different architecture: client-side proving. The user executes and proves their own transaction locally and the network only verifies the proof, so the chain never handles the data at all. That inverts the usual privacy trade-off, in which some operator has to be trusted with plaintext, and it is one of the more ambitious designs anyone is actually building. Mainnet is planned for September 2026, about a year later than first sketched, and because proving on ordinary devices is demanding, the design also supports delegating proof generation to a service for users whose hardware cannot carry it.

What is zero-knowledge proofs?
One party proves a statement about hidden data is true without revealing the data the statement is about.
How it compares with the other approaches on latency, trust assumptions and fit is set out, with sources, in the technology taxonomy.
Private by design.
