Capability 1 of 4
Secure Storage
Everything your systems record becomes a secured, self-proving record, at the edge or in the data centre.
At capture
Secured the moment it is written.
- Every entry is secured automatically
- Trust can be anchored in the device itself
- The origin and authenticity of every record can be proven
- Users can sign their records for accountability
Every record proves itself from the first write.Alteration is detectable, immediately and forever.
Any data, any system
From a status message to a multi-gigabyte file.
- Documents, files, telemetry, database exports, or any other data type
- Runs on any device, from IoT to an enterprise server
- No noticeable overhead, even at high volume
- Large files and live streaming are supported
- Fully offline when required
One secured form, from IoT to headquarters.No size ceiling. No speed tax.
Nothing lost
Updates add. They never replace.
- Corrections are added as new entries while the past stays
- Previous versions can be restored when needed
- You can re-trace any moment in the record’s history
- A complete audit trail exists by design, not by policy
The past stays. Corrections only add.A complete audit trail, by design, not by policy.
Versus blockchain
Blockchain’s strengths. None of its baggage.

Frequently asked questions
Secure Storage questions, answered directly.
What if a record is wrong, can I still change it?
Yes. Write the correction as a new entry. The original stays, the full history is preserved, and earlier versions can be restored. Tampering and supply-chain attacks are different: they try to change a record without leaving a trace. Those changes are detected. The altered record no longer proves it is genuine, immediately and permanently.
If everything is preserved, will this take too much disk space?
It does not have to. The full history is kept, but it does not all need to stay on the working disk. There are several mechanisms to reduce the size of active storage. At a periodic checkpoint, storage can be compacted: the full audit trail moves to cold storage, and only the latest version stays active. Complete files can also move to secondary storage, while the record still proves it is genuine. Request a briefing to discuss the right approach for your environment.
Do we need special hardware?
No. Special hardware is not required. NxChain runs on ordinary devices, from IoT to an enterprise server. A TPM or a hardware security module (HSM) can be used when you want stronger trust. It anchors the record to a specific device or vehicle, so the origin is tied to that hardware. That improves authenticity and security. It is optional. People can also sign their own entries. A smart card or another electronic signature ties the record to a named person, so accountability sits with whoever wrote or approved it. That is optional too.
Can it handle large files and live data?
Yes. NxChain was designed for this. Other blockchains keep files outside the chain. That means two systems to keep in step: the chain, and a separate file store. They have to stay synchronised while living apart. In a deployment, files go missing or arrive corrupted, and you maintain both sides at once. NxChain keeps the files inside the record, with no noticeable overhead. A whole dataset, including many files, travels as a single NxChain file. Live data is the same idea. It is delivered as it arrives, without waiting for a batch to close or hitting the usual bottlenecks. Proof of authenticity travels with the stream, so the receiver can verify the data while it is still coming in.
If every record proves itself, can anyone read it?
No. A record can prove it is genuine without exposing its contents. Data remains private. It does not need to be shared. Sharing is a decision you make, not a prerequisite for storing the record. If you do share, the recipient can verify integrity without seeing more than you released. Other nations, organisations, or industry partners can check the digital signatures for themselves, even outside your own systems. When you do choose to share, Reliable Distribution is the next step: getting the record to the people who need it, and only them.
