Blockchain and internet of things (IoT) is a combination that has massive potential to bring about revolutionary changes in various useful applications/ industries by enabling secure and transparent data exchange, decentralized control, and improved efficiency. However, this convergence also requires significant security, privacy, and technical challenges that must be addressed for successful implementation and widespread adoption. This chapter explains the security, privacy, and technical challenges that arise in a blockchain-IoT-based environment. Firstly, it examines the security issues related to the distributed nature of blockchain networks and the vulnerabilities that can be exploited in IoT devices and communication channels. Further, the authors discuss the importance of cryptographic techniques, secure key management, and access control mechanisms to protect data integrity and prevent unauthorized access.
