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. If your cloud provider has a US parent, your data is exposed to the CLOUD Act — regardless of where the server sits.
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 — even if it is stored in Frankfurt or Paris. Contractual promises do not override US law.
Healthcare (HDS), finance (DORA, NIS2), and government sectors increasingly mandate that data physically resides within national borders. A "region picker" on a cloud console is not proof — it is a configuration setting that can change without your knowledge.
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. The gap between "we say we're compliant" and "anyone can verify we're compliant" is the gap ATSHI closes.
A virtual network is a subset of the ATSHI mainnet. You select which nodes participate, and transactions are replicated exclusively to those nodes — nowhere else.
Virtual Network Architecture
Most platforms encrypt data and broadcast it everywhere. ATSHI takes a fundamentally different approach: your data is physically confined to the nodes you choose.
Data is replicated to every node on the network, but encrypted. All nodes store your data — they just cannot read it. The data physically exists on machines you do not control, in jurisdictions you did not choose. A future cryptographic breakthrough or key compromise could expose everything retroactively.
Data everywhere, encrypted
Data is replicated only to your selected nodes. Nodes outside your virtual network never receive the data at all — not encrypted, not hashed, not in any form. The data physically never exists on machines outside your perimeter. There is nothing to decrypt because there is nothing to intercept.
Data only on your nodes
From definition to deployment in minutes — no separate chain, no dedicated infrastructure, no complex ceremony.
Name your virtual network and set governance rules: who can administer it, who can submit transactions, and how membership changes are approved.
Choose which mainnet nodes will participate. Filter by geographic location, cloud provider, certifications, or any custom attribute. Only matching nodes are included.
Your virtual network is activated on the ATSHI mainnet. The selected nodes begin accepting transactions for your network. Same protocol, same consensus — isolated scope.
Every transaction created in your virtual network is replicated exclusively to your node subset. Data never leaves the perimeter. Complete physical isolation is enforced at the protocol level.
Validators sign geographic and regulatory attestations that are anchored directly to the ATSHI mainnet. Every compliance claim is a living, verifiable cryptographic proof that updates in real time — not a PDF certificate buried in a drawer.
6 Compliance Levels
Physical isolation, cryptographic proof, and full regulatory coverage — on a public mainnet.
Data physically never leaves your defined perimeter. Not encrypted elsewhere — simply not there. You control exactly which machines hold your data, in which countries, on which providers.
SovereigntyEvery sovereignty claim is backed by cryptographic attestation anchored on-chain. Auditors verify math, not marketing materials. Compliance is provable, not promised.
ComplianceNo US parent company means zero exposure to US government data requests. Your data is governed exclusively by European law — period. No legal backdoors, no jurisdictional ambiguity.
SecurityYour virtual network runs on the ATSHI mainnet — same protocol, same consensus, same security model. No chain bootstrapping, no genesis ceremonies, no orphaned infrastructure to maintain.
ArchitectureHDS certification for patient data, DORA and NIS2 for financial institutions, MiFID compliance — all built into the protocol. Deploy regulated applications with confidence.
RegulatedDefine your node criteria, set governance rules, and deploy. Your virtual network is live in minutes, not months. No hardware provisioning, no DevOps overhead, no chain bootstrapping.

From regulatory compliance to enterprise data control — virtual networks solve real problems that encryption alone cannot address.
European personal data must stay in the EU. Create a virtual network restricted to nodes physically located in EU member states. Data never touches a server outside Europe — not encrypted on a US server, not stored anywhere outside your jurisdiction. True GDPR compliance by design, not by policy.
RegulatoryEnterprises need guarantees that their operational data is not co-located with competitors or untrusted parties. A virtual network gives you a dedicated perimeter on shared infrastructure — your data only exists on nodes you have vetted and approved. No shared storage, no shared replication.
EnterpriseMultiple organizations in a supply chain need to share data — but only among themselves. Define a virtual network with nodes operated by consortium members. Suppliers, manufacturers, and distributors share a common ledger that is invisible to the rest of the network.
Supply ChainPatient records and health data are subject to strict national regulations. Create a virtual network restricted to nodes within your country's borders, operated by certified healthcare infrastructure providers. Medical data physically never leaves the national perimeter.
