Define which nodes store your data — by geography, provider, or certification. Transactions are physically isolated to your perimeter. Compliance is not a vendor promise — it's a cryptographic proof on-chain.
European regulation is clear: personal and sensitive data must stay within jurisdictions you control. The reality of most infrastructure makes that impossible to prove.
The GDPR requires that personal data of EU residents is processed lawfully and transparently. The Schrems II ruling invalidated the EU-US Privacy Shield, making transfers to US-controlled infrastructure legally precarious.
The US CLOUD Act compels American companies to hand over data stored anywhere in the world when served with a warrant. Using AWS, Azure, or GCP means your data is one subpoena away from US government access.
Healthcare (HDS), finance (DORA, NIS2), and government sectors mandate that data physically resides within national borders. A "region picker" is not proof — it is a configuration that can change.
Your data should physically stay where you decide, not where a vendor decides. Today, compliance is a promise in a PDF. Tomorrow's regulation demands mathematical proof.
Data is replicated to every node, but encrypted. All nodes store your data — they just cannot read it. The data physically exists on machines you do not control.
Data is replicated only to your selected nodes. Outside nodes never receive the data — not encrypted, not hashed, not in any form.
Sovereignty is not just where the data sits — it is who runs the silicon and who wrote the code. ATSHI runs on a curated list of European cloud operators, powered by a French-built blockchain protocol.
Nodes in your European virtual networks are exclusively hosted by operators headquartered and incorporated within the European Union (or EEA-equivalent). No US parent companies, no Chinese subsidiaries — only operators answerable to European law.
ATSHI Network is designed, developed, and audited by a French team. The codebase is open-source under European licensing. No US-controlled dependencies, no offshore maintainers — the protocol is governed by an entity subject to French and European law.
Name your virtual network and set governance rules.
Filter by geographic location, provider, or any attribute.
Your virtual network is activated on the ATSHI mainnet.
Every transaction is replicated exclusively to your subset.
Deploy on the only blockchain where data sovereignty is cryptographically verifiable. Stop relying on vendor promises. Start proving compliance with mathematics.
