A snapshot of the original idea.

These v0.1 white papers were first prepared October 11, 2026 and have since been edited for privacy, terminology, and focus. The live proof of concept has continued to evolve: some terminology and implementation details in the documents predate the current Trade Stack site. Proposed integrations and policies are illustrative, not announced partnerships or operational services.
