Navier–Stokes: The VortexFlow Framework — Distributed Equation Processing and a Post-Quantum Currency

This research preprint proposes VortexFlow, a framework for distributed equation processing and a native digital currency using post-quantum signatures and Byzantine fault tolerant consensus. It separates experimental fluid-based cryptographic hypotheses from the assumptions securing transactions, describes enterprise workloads and settlement, and includes four scoped theorems with proofs. A standalone Rust experiment evaluates a periodic one-dimensional heat equation at four grid resolutions. Measured errors, analytical references, verification checks, and reproduction commands are included. These results concern numerical accuracy, not network latency, deployed blockchain performance, three-dimensional Navier–Stokes regularity, or quantum immunity.
