Cryptographic Techniques for Securing Blockchain-Based Cryptocurrency Transactions Against Botnet Attacks

Abstract

This chapter analyzes the most sophisticated cryptography methods which are used to protect blockchain-based cryptocurrency transactions against attacks by botnets. First, a background will explain blockchain, cryptocurrencies, and threat space for bots is going to sing in. Core cryptographic building blocks such as hash functions and digital signatures are outlined. The chapter furthermore outlines methods to confront botnet threats in blockchain ecosystems, including two processes to sign the user charting, a sign policy standard, code signing, attestation, multi-party computation for private transactions, and zero-knowledge proofs. Finally, we present some obstacles and ideas for research along the way. Conclusively, the systematic incorporation of cryptographic defenses would be the providing layer of security as well as the guarantee of the integrity of cryptocurrency transactions. Continual improvements in scalable cryptographic algorithms and their implication in blockchain platforms will make secure mechanisms against botnets possible.
