Assignment Title: Analyzing and Fortifying Cryptocurrency and Blockchain Security

Objective: The goal of this assignment is to investigate the security landscape of blockchain and cryptocurrency technologies. Students will explore known vulnerabilities, how they can be mitigated, and the ethical implications of cybersecurity in the domain of decentralized finance.


1.   Describe the architecture of blockchain technology and how it underpins cryptocurrencies. How does this architecture aim to provide security and trust?

2.   Research and summarize past security breaches in cryptocurrency systems. What vulnerabilities were exploited in these breaches?

3.   Discuss the ethical considerations of a cybersecurity professional in the context of blockchain and cryptocurrency systems. Why is it important to adhere to ethical standards?

4.   Identify the common vulnerabilities in blockchain systems (e.g., 51% attacks, smart contract vulnerabilities, etc.) and explain how they can be mitigated.

5.   How does the transparent nature of blockchain transactions impact security and privacy? Discuss potential trade-offs.

6.   Examine the role of consensus algorithms in the security of blockchain systems. What are the strengths and weaknesses of popular consensus algorithms like Proof of Work (PoW) and Proof of Stake (PoS)?

7.   Explore the concept of “security through obscurity” vs. “open-source security” models in the context of blockchain technology. Which approach is more prevalent in the blockchain space, and why?

8.   Consider the future of blockchain security: What emerging technologies or methodologies could potentially bolster the security of blockchain and cryptocurrency systems?
