Public blockchains can be used as an independent platform for proving traceability through the supply chain from mine to consumer, as they can be decentralized and provide an unalterable record. We wanted to utilize this blockchain technology to not only claim the quality and ethics of RURI's jewelry, but also prove them to our customers. We believe strong branding is not only for customers and company, but more importantly for our supply chain participants who create value of the brand every day. Blockchain cannot prove claims that have not actually been made. We will build transparent business and deliver true quality to our customers by working on daily traceability with the help of blockchain in every important step of every product.

Tracified, our technology partner, develops the proprietary traceability system based on blockchain technologies. In order to ensure a high degree of authenticity in the data that are entered into the system, Tracified provides multiple proofs based on blockchain smart contracts. This will include Proof of Existence (verification that a piece of data has not been changed after being entered into the system), Proof of Continuity (verification on the end-to-end traceability history of an item), Proof of Genesis (verification that a given item is genuinely coming from the shown supply chain and not from elsewhere), Proof of Change of Custody (verification that the item has moved between stakeholders in the value chain exactly as shown) and Proof of Genuine Spending (verification that item quantities are not manipulated for price advantage). A public web application (Blockchain Explorer) will be provided to access and audit these proofs.

Additionally, RURI can compose a digital twin of a gem using proven records on Tracified blockchain and tokenize it to Cross Reality Token® (+RT®) on blockchain.
