Oxford professor Guillaume Chapron described the possibilities of blockchain in the field of environmental protection. His article is published in the Nature journal.
According to the author, if using blockchain, it is possible to organize the expenditure of common resources. For example, it is possible to use hash codes for felled timber: the code will be changed after each stage of the entire supply chain, form timber exporting to its sale. In such a way, end users will know that the tree was cut down legally.
Unlike paper documents, data in the blockchain can not be faked. This advantage has already been used by the Walmart network, which decided to experiment with the introduction of blockchain into the process of pork delivery from China.
