The British startup PREVENANCE is going to support sustainable fishing using blockchain
Every third fish, which has been on sale, is not the one that seems. These are the conclusions of the Oceana organization, which deals with the preservation of the marine environment. As part of the study, control purchases of more than a thousand fish were made, and almost 30% of the copies did not correspond to the name that was indicated.
The greenhouse previously wrote about the Fishazam project - a device that uses infrared spectroscopy to determine the type of fish. The British company Provenance offers a larger way to control the supply of fish - using a blockchain .
The idea of blockchain technology is a chain of blocks with information about each transaction (transmitting something from one user to another), which is stored in each unit of the network of computers. Blockchain technology provides a person with the opportunity to create a digital recording of datathat cannot be refuted or hack in order to make changes .
Now fish trading is fixed on paper, and the marks made on it help to track the fish. The idea of Provenance is that the fishermen will have to send an SMS message in order to register their catch in the blockchain.
The digital code of the party comes to the fish supplier, and each further iteration (for example, fish processing) is also fixed in the chain. Information about the origin of the fish and the supply chain can be then available to the final buyer or consumer in a store or restaurant using a smartphone.
The service is tested by a group of grocery cooperatives, the trial period will last until the end of the year. The use of technology increases the cost of fish by several pands, so initially it can be applied to more expensive varieties of fish, so alas, we are not talking about fish conservatives.
Under the pressure of the public and NPO campaigns, fishing in the world is already beginning to present stability and large retail chains. So, the Tesco supermarket chain removed its John West fish brand, the supply of fish for which the Thai Union, the world's largest supplier, Tunets. Claims related to the origin of the fish and the method of extraction were presented to the unification - whether the norms of fishing in this region were observed, whether human rights were violated with fishing.
