The C.I.A Properties of Web3 System

This chapter examines the aspects of the confidentiality, integrity, and availability (CIA) triad to blockchain technology from a cybersecurity perspective. The CIA triad is a fundamental concept that forms the basis of effective information security measures. The chapter discusses the importance of each of the CIA triad properties in protecting sensitive information and maintaining reliable systems. The chapter argues that the CIA triad is still relevant in the Web3 era, where blockchain technology is at the core of value-based and self-sovereign information systems. The chapter explores the unique advantages and challenges of blockchain technology in terms of the CIA triad. Regarding confidentiality, the chapter discusses the limitations of pseudo-anonymity in providing sufficient confidentiality of blockchain data without privacy-preserving technology or protocols. In terms of integrity, the chapter examines the immutability of the blockchain ledger and the importance of security and liveness in consensus algorithm design to ensure data integrity. Finally, the chapter addresses the availability of blockchain, which relies on data replication, scalability, latency, and on-chain and off-chain data. By understanding the CIA triad and its application to blockchain technology, security professionals can effectively prioritize and allocate resources to protect information and systems in the Web3 era.
