OpenChainGraph · Industries Showcase

Any industry's decision, rendered as a verifiable chaingraph

A curated gallery. Each built exemplar is a real OpenChainGraph node with a server-parity kernel, a frozen fixture, and a client-side execution hash you can recompute yourself. Together they prove the same stack behind our career and education tools turns any domain's provenance or decision problem into a runnable, hand-off-ready artifact. Deterministic decision engines for people, creators, and agents.

① Generative Art & Visuals

Hash-Seeded Generative Art

One seed draws the SVG and fixes the hash; the same seed always regenerates the identical artwork and execution hash. The purest reproducibility demo, and the gallery's cold open.

② Gaming & Interactive

ARG Puzzle Gates

Solve the clue; the answer's fingerprint drives a decision gate that routes a correct answer forward and a wrong one to end. The clearest both-branch gate demo in the creative set.
