SDiX to run trials of first blockchain verification

19 june 2017
Singapore Diamond Investment Exchange (SDiX) has announced that it will soon complete the first part of a “Proof-Of-Concept of a blockchain-based authentication and secure record-keeping service for trading diamonds on a global commodity exchange.”
SDiX is the world's first commodity exchange in physically settled diamonds in partnership with Kynetix, the physical commodity digitisation expert, and Everledger, supplier of blockchain and distributed ledger infrastructure.
An initial trial run was successfully completed when the solution “accurately authenticated the key details of a consigned diamond basket on SDiX consisting of GIA-certified stones using unique data points hosted securely online”.
SDiX says that a key part of the output is a "view receipt" of the digital certificate for each stone in the basket, housed on the blockchain. The system opens up the potential for a range of future applications for diamond market participants, including enhanced provenance data, increased supply chain security and efficiencies, and new risk management tools.
Linus Koh, CEO of the Singapore Diamond Investment Exchange, said: "This exciting collaboration builds on SDiX's record of delivering advanced technologies to enable a trusted, fair and transparent marketplace for trading diamonds as an investable asset class. This new concept draws on blockchain's distributed ledger capability to demonstrate how we can further instil confidence and convenience for the benefit of diamond investors and financiers."
