Abstract
Blockchain security is fundamentally based on several cryptographic mechanisms that maintain transaction integrity, confidentiality, and authentication, and it is the pinnacle of technology today. This paper analyses various cryptographic techniques embedded in blockchain. These techniques include data encryption, digital signatures, and hashing. The following discusses the different consensus mechanisms that enable scalability and integrity in a blockchain, with an emphasis on proof-of-work and proof-of-stake. Nevertheless, there are problems relating to 51% attacks, scalability issues and privacy concerns thereof in a blockchain. To assess users' knowledge and perceptions of blockchain technology security, we will conduct a survey to analyse levels of knowledge, usage trends, and concerns about digital currency security. The results will provide insight into current knowledge of blockchain cryptography and indicate possible areas for strengthening security.
Keywords: Blockchain Security, Attacks, Cryptography, Encryption, Digital Currency.
