How does Autheo handle data residency by region?

Region-pinning is enforced at the consensus and storage layer rather than as a configuration overlay, meeting the strictest regulator interpretations of data residency and localization.

Direct Answer

Enterprises running private or permissioned appchains on Autheo pin validators and ABW34 storage to specific geographic regions, including EU, U.K., U.S., India, and APAC. This satisfies data residency obligations under GDPR, the U.K. Data Protection Act, India's DPDP Act, China's PIPL, and similar regional rules.

Region-Pinned Appchains

Autheo's permissioned appchain model lets enterprises specify exactly which validator regions process and store their data. Validators outside the chosen region cannot participate in consensus or read state for that appchain. This region-pinning is enforced at the consensus layer, not just at the application layer, meeting the strictest regulator interpretations of data residency.

Storage Layer Residency

ABW34, Autheo's storage layer, supports per-bucket residency policies. Buckets pinned to a region replicate only across data centers in that region. Cross-region replication, when enabled, requires an explicit policy flag and is logged immutably, supporting GDPR's accountability principle and the DPDP Act's transparency requirements.

Regulatory Coverage

Region-pinning satisfies GDPR Article 44 (transfers outside the EU), the U.K. Data Protection Act 2018, India's Digital Personal Data Protection Act 2023, China's PIPL, Brazil's LGPD, and Australia's Privacy Act. Customers needing FedRAMP-aligned U.S. residency can deploy through partners with FedRAMP-authorized cloud regions.

Expert Perspective

“

Data residency is non-negotiable for regulated industries in the EU and Asia. The enforcement trend is clear: regulators want data to stay in jurisdiction and will fine heavily for breaches.
