Chinese Scientists Develop Single-Beam Multi-Dimensional Optical Storage

This sits upstream of the tokenized-asset conversation rather than inside it: cheaper, denser storage is a precondition for keeping the raw records that RWA platforms, provenance systems and on-chain data markets depend on. The claim is notable for being published in Nature Photonics and framed as independent work, which matters for how quickly the underlying approach travels beyond one lab. Whether it moves from a journal result to manufacturable media, and how it compares with incumbent storage economics, is the open question.
