A Python Programming Initiative for Hash Construction through the Example of SHA-2 | Chapter 8 | Finite Abelian Groups, Elliptic Curves, Blockchain with Hashing and Graphs

 

As opposed to the different methods used in the preprocessing and concatenation steps associated with Secure Hash Algorithm 1 (SHA-1), we treat here the case of Secure Hash Algorithm 2 (SHA-2) that is still unbreakable up to the present. In addition, before its implementation in Python, we first explain the difference between the two approaches.

Introductory Essentials to Blockchain, Hashing and Graphs | Chapter 4 | Finite Abelian Groups, Elliptic Curves, Blockchain with Hashing and Graphs

 

The present study explains the reasons behind decentralization and introduces the basic concepts of blockchain technology with clear references to its key components, such as consensus mechanisms and peer-to-peer networks. An explanation of hashing is treated with different examples of classical algorithms, as this is very important in blockchain signatures. A brief introduction to graphs is also presented since they are used to develop decentralization and counterattacks. Finally, we introduce 16 exercises on these two elements.
