from the mine to the factory
Stannol is committed to disclosing the supply chain of its tin used. With this transparency, we guarantee that social and environmental standards are met. To implement this project, Stannol is working with Minespider, a company that specialises in blockchain technology. With the help of digital certificates, this technology enables the tin to be traced back to its origin without any gaps or forgery.
HOW DOES THE BLOCKCHAIN WORK
Behind the term blockchain is a technology used by various cryptocurrencies, for example: A decentralised structure for managing and verifying transactions secures it against subsequent manipulation. In a blockchain, the actors involved store information in data blocks that are linked to each other. The information stored in the blocks must also be verified by everyone. The data provided is thus traceable at any time, tamper-proof and thus trustworthy.
The Minespider blockchain software creates digital certificates along the supply chain that document the origin and supply route of the materials. With the help of QR codes on the products, the history can then be viewed digitally.
THE MINESPIDER PROTOCOL
To ensure that sensitive supply chain data is protected despite the open source approach, the software relies on a data structure consisting of three levels: At the first level, information is passed on for everyone to see. These become visible when the DMC code is scanned. On the second level is the data that is to be shared along the entire subsequent supply chain. On the third level, confidential data can be communicated - this level can only be seen by the sender and the recipient of a digital certificate.
