Architecture & System Design of TERRA+: The wine production use case

The paper presents the architectural design and the technical details of the TERRA+ platform, an Ethereum based Blockchain infrastructure aiming to address the lack of confidentiality among consumers and producers in the agrifood sector. TERRA+ first application on the wine supply chain is presented; aiming to facilitate winemakers to build their brand's integrity via employing blockchain technology as the driving force of the proposed solution. Particularly, the presented approach, empowered by blockchain technology, is expected to (i) increase food confidence by leveraging blockchain technology and IoT, (ii) support brand integrity by providing all involved parties with data insights towards unique characteristics acquired from the vineyard origin and the producers and (iii) digitize food business models by allowing consumers and/or 3rd party services to capture robust data collections about each product.
