Blockchain for Digital Twin

Security and privacy are critical issues in digital twin edge networks. Blockchain, as a tamper-proof distributed database, is a promising solution for protecting data and edge resource sharing in digital twin edge networks. In this chapter, we first introduce the architecture of the blockchain-empowered digital twin edge network, to show the integration angles of the blockchain and digital twin techniques. Then, we show the block generation and consensus process in the developed blockchain-empowered digital twin edge network architecture.
