MARINE FUELS

By the time trail that follows the fuel, and any changes made to it, through- it reaches a vessel, there will be an entirely auditable trail of tags out the supply chain and records all activities and sign offs by contained in the fuel, which upon lab analysis, will reveal the as- actors transacting the fuel. It provides assurance of quality, sociated data regarding that fuel. including meeting permissible ISO specifcations or fagging

The addition of a molecular label alongside the DNA tag acts a potential contaminant introduced at any point of the supply as a covert screening tool which allows crew and/or independent chain, and in the future we hope it will be an application which surveyor to be able to test for the presence of the necessary DNA could be used to trace solutions of pollution. This unique tag is markers and, if they’re absent, make a decision about whether to linked to key data about provenance, location, chain of custody proceed. Where the DNA markers tag the provenance and move- and any information, which is deemed relevant. The two tech- ment of the actual fuel, the blockchain solution traces interactions nologies combine to provide a powerful framework which links that occur on a human-to-human level – the digital ‘handshakes’ the digital world with the physical world, therefore tracking the that occur along the journey of the fuel. entire supply chain by integrating blockchain with DNA tracing

The result is a solution combining both elements of DNA and in one solution.
