A Blockchain Based System to Ensure Supply Chain

Abstract

We propose a blockchain oriented platform to secure stor- age origin provenance for food data. By exploiting the blockchain dis- tributed and immutable nature the proposed system ensures the supply chain transparency with a view to encourage local region by promot- ing the smart food tourism and by increasing local economy. Thanks to the decentralized application platforms that makes us able to develop smart contracts, we define and implement a system that works inside the blockchain and guarantees transparency, reliability to all actors of the food supply chain. Food, in fact, is the most direct way to get in touch with a place. The touristic activities related to wine and food consump- tion and sale in fact influence the choice of a destination and may encour- age the purchase of typical food also once tourists are back home to the country of origin. Touristic destinations must therefore be equipped with innovative tools that, in a context of Smart Tourism, guarantee the orig- inality of the products and their traceability.
