Block DT: Blockchain for Protecting Security and Sustainability for Digital Twins using Digital Passport
The aim is to develop a digital passport based on the Ethereum blockchain technology for digital twins and thereby improve the security of data management. This passport serves as a secure repository for important data such as model data, functional descriptions and parameters for calculating the CO2 emissions generated by the corresponding real device during its life cycle and forecasts of these emissions.
The Ethereum blockchain provides a decentralised platform that supports smart contracts. These are self-executing contracts with the terms of the agreement directly in the code. The Ethereum blockchain is characterised by decentralisation, transparency and security. There is no central controlling authority, which makes manipulation more difficult, and all transactions are publicly visible, which increases the traceability and verifiability of data. Cryptographic algorithms protect the data from unauthorised access and manipulation.
Implementation on the Ethereum blockchain could include the creation of a smart contract that defines the structure and rules for the digital passport, including the storage of data, access rights and conditions for updates and queries. Each record in the digital passport could be cryptographically signed and stored on the blockchain to ensure its authenticity. Access to different parts of the digital passport could be controlled by Ethereum accounts and permissions.
In summary, a digital passport based on the Ethereum blockchain for digital twins provides a secure and transparent means of managing data and carbon emissions. This technology can significantly contribute to optimisation and sustainability in various industries.
