The Diamond Time-Lapse Protocol, launched in February this year, is the industry data protocol using blockchain to track the provenance of diamonds.
A Data Matrix code, which is a two-dimensional code consisting of black and white ‘cells’ or modules encoded with data, is inscribed on the girdle of a diamond, providing a mechanism to cryptographically sequence information about the diamond. This information includes the origin of manufacturer, unique serial number and object details.
The use of Data Matrix code was selected due to its ability to encode a large amount of data in a small amount of space and has been popular in asset tracking, and is underpinned by the use of rolling code to ensure that only a unique code is generated.
With this, Everledger has enabled an IoT (internet of things) bridging of the digital twin of a diamond’s provenance on the blockchain with the physical diamond, which brings about a concurrency of identity. Fully implemented with Dharmanandan Diamonds, this ensures the veracity of the diamond’s information encoded and subsequently viewed by the user.
A Mobile Inscription Viewer is available to scan the code and is integrated with the Diamond Time-Lapse iOS and Android applications developed by Everledger, for the user to view the diamond information.
Currently, the provenance of 7,500 diamonds from Dharmanandan Diamonds have been encrypted onto the blockchain platform. Following this, a production scale of 10,000 diamonds monthly has been anticipated.
