eDNA: A Decentralized Marketplace Architecture for the Automotive Sector

In the context of the digital transformation driven by the Internet of Things (IoT), various sectors of the economy, including automotive, are undergoing renovations. With the advancement of Web 3.0, innovative solutions in data management, information security, and data ownership are emerging. Due to the adoption of IoT concepts in the automotive sector, a vast amount of data is collected and transmitted to manufacturers without the owners’ consent. This paper proposes the eDNA architecture, based on blockchain and IoT, to create a decentralized automotive data marketplace. eDNA utilizes the Polygon network, IPFS/IPNS, and smart contracts to securely and transparently store, protect, and share data, promoting owners’ inclusion in the automotive data market. In the implementation of eDNA, using synthetic data, transaction fees remained consistent and accessible, proving the viability of the architecture.
