In this chapter, we will focus on the security assumptions underlying blockchain technology and distributed ledger technology (DLT), examining in detail the advantages and disadvantages associated with each technological architecture.
After examining the characteristics of the decentralized model typical of blockchain and DLT, we will learn about the current threats to blockchain and DLT. We'll also discuss the potential future threats related to the spread of quantum computing, which represents a real risk not only for blockchain technologies but for all architectures that base their security on cryptography.
The topics we will cover in the chapter are the following:
- Centralized models versus decentralized models
- Advantages and disadvantages of blockchain
- Blockchain versus DLT
- Understanding transaction security
- Attacking a blockchain
- Understanding...
