Blockchain Security
Other than scalability and privacy, there is another challenge that needs to be addressed in order for blockchains to become even more trustworthy. The issue is that of security. The security of blockchain is crucial because it is the backbone of many use cases, including sensitive ones like healthcare, finance, and supply chain management. With the advent of DeFi, it has become even more important to ensure the correct functioning of blockchain so that there are no vulnerabilities left in the blockchain that could be exploited, resulting in a loss of funds or other unintended consequences.
As the blockchain ecosystem is composed of several layers, there are security concerns at every layer, and we’ll discuss them in this chapter. There are also layer 2 (side chains, etc.) related security concerns, which we’ll also shed some light on in this chapter.
We’ll cover the following topics in this chapter:
