Frequently asked questions

If Timber Chain is recording data on an immutable ledger, does this mean that data cannot be edited once it is recorded?

Timber Chain provides its users the ability to edit already recorded data, however, each change is reflected in the history of the record, with “old” information still being available for checking against the records on the immutable ledger.

For example, if a user has made a typo in the name of the mill that has processed the wood in a particular stock – they can simply edit the information and save it, which will result in the following steps:

 

    1. The stock information will be updated;
    2. A new claim will be created on the iov42 immutable ledger with the new information (the old claim with the typo will still be available);
    3. A new item will be added to the history section of the stock showing which value has changed;


Those who have access to the stock information will now be able to see which change has been made, but will also be able to approve what the previous value has been and all of the verifications (digital signatures / endorsements) that value has had.

Since data is recorded on a “blockchain”, does this mean that everyone can see it?

iov42’s core platform is a permissioned DLT (distributed ledger technology) solution, which means that its users determine who has access to their information (and which information as well) stored on the immutable ledger (“blockchain”).

Additionally, the data on the immutable ledger is stored in hashed form, which means that it cannot be made use of unless the person checking it has the original (unhashed) data available to be able to hash it and compare it to the hash stored on the immutable ledger.

The data stored on Timber Chain (i.e. outside of the iov42 immutable ledger) is also protected by a set of permissions that the users can either grant or restrict. For example, the shipment data only becomes available to the importer once the exporter has established a connection with them and has explicitly shared the shipment data with them.

Do all my suppliers and customers have to be on Timber Chain for me to use it?

No. We realise the fact that some organisations might not have the capacity or the means to upload their data to Timber Chain, therefore, we allow downstream members to upload data on behalf of their upstream suppliers. This ensures that full traceability data is available for due diligence and auditing purposes.

We also provide the means for Timber Chain users to share their outputs (shipments / deliveries / sales / etc.) with their customers who are not members of Timber Chain. This can be done via password-protected share links that are limited to one entity (i.e. 1 shipment / 1 delivery / etc.).

Can data be migrated from my existing system to Timber Chain?

Yes. We provide our users with the ability to upload XLSX files with data exports from their existing systems. This data can then be uploaded to Timber Chain and recorded on the immutable ledger (“blockchain”) in one go.  Document scans / digital documents can also be included by archiving both the XLSX file and the documents (in PDF format) and uploading the archive onto Timber Chain.

Which certification standards does Timber Chain support?

Timber Chain is standard agnostic, and is also suited for non-certified timber. This means that even organisations that are not pursuing certification, but still would like to demonstrate the soundness of their operations (by providing all of the necessary information to their customers and authorities) can use Timber Chain to trace their wood-based products.
