The data in Exact Trace® is anchored in Hedera through the public network Hedera Hashgraph. This makes the solution a hybrid blockchain solution.
As a user or regulatory body, you can verify for yourself that the data has not been manipulated, and thus have full confidence in solutions marked "Powered by Exact Trace".
How traceability and trust are related
Exact Trace® is designed to make the flow of goods and reporting to the authorities both easier and more reliable. The solution also ensures that data cannot be changed without being detected.
Our customers have their own “blockchains”, which we call EventStreams. This is a continuous history where new events are based on previous data. This means that if something changes afterwards, it will be visible.
The data is thus consistent internally in the system.
But how can others be sure that this is actually true?
This is where the anchoring in Hedera comes in.
What does this mean?
When something is registered in Exact Trace®, a digital proof is created that the event has occurred. This proof is stored in a public network that Sone 4 AS has no control over.
This means that:
- Data cannot be changed afterwards without being detected
- The information can be verified by an independent third party
A little about the technology
Hedera is a public platform that makes it possible to store such evidence in a secure and efficient way.
You can think of it as a shared logbook that no single actor fully controls. Once something is recorded, it stays there.
Exact Trace® uses this technology as an extra layer of security and trust.
What is a hybrid solution?
Exact Trace® is a hybrid blockchain solution because we combine a regular IT system with public verification.
This means that:
- Data is handled quickly and efficiently in the solution
- Evidence of the data is stored externally and independently
- Secure and verifiable reporting to authorities
- Better documentation during control or audit
- Increased trust between actors in the value chain
The hybrid approach is central to the TRACELAND project, where the goal is better traceability and transparency when landing wild-caught fish.
