Data Consulate: embassy-style trust logic as a technical regime for cross-border data processing

This preprint introduces Data Consulate, a proposed institutional and technical regime for hosting Foreign Party Content inside a data centre located in a Host State under a controlled cross-border governance model. The core idea is to combine (i) procedural access rules (predictable request/response workflows and logging), (ii) cryptographic control designed to prevent silent access to readable content, and (iii) independent verifiability through audit. I position Data Consulate as a practical evolution of the “data embassy” concept: moving from ad-hoc, bilateral continuity arrangements toward a standardisable, accreditable framework that can support everyday cross-border services while preserving jurisdictional clarity for limited purposes. The paper also frames Data Consulate as a digital confidence-building measure (CBM) and discusses geographic and political-economy conditions that make certain regions—especially legacy industrial areas with abundant power and existing infrastructure—plausible candidates for hosting such regimes. The contribution is a clear definition, a minimal actor model, and a set of operational invariants and accreditation requirements intended to make “jurisdiction + control” implementable rather than purely rhetorical.
