De Beers mulls diamond traceability platform anchored by blockchain technology

06 december 2017
De Beers said it is investing in a new platform that will provide a single, immutable record that traces a diamond’s individual journey through the value chain.
Group chief executive Bruce Cleaver said in a note that the diamond traceability platform was underpinned by blockchain technology, which allows for a highly secure digital register that creates a tamper-proof and permanent record of interactions.
“In a blockchain, each event or transaction is registered in a database backed by advanced information security technology,” he said.
“This chain maintains a record of the activities that have taken place, the order they occurred in, who they occurred between and what they involved.
“However, and what is most unique about this project, is that the system is able to verify activity on the chain without needing to reveal sensitive details to the wider community. As a result, participants can be confident that a transaction occurred, but safe in the knowledge that the sensitive data remains between them and their counterparty.”
Cleaver said once established, the blockchain would operate as a shared platform, on top of which a range of solutions could be built.
“It can be thought of as akin to a smartphone and a range of apps – once the base blockchain technology is established, participants in the ecosystem can build applications for various uses, whether that’s as a trading platform, financial assurance tool or consumer-facing solution,” he said.
“As the first traceability platform to span the entire diamond value chain, the solution we are developing aims to provide unprecedented levels of confidence and assurance for all stakeholders.”
