This course provides a deep introduction to the theoretical and practical foundations of blockchain technology. Students will explore how blockchains work, why decentralized systems are secure, and how consensus protocols enable trustless communication across distributed networks. The course starts with an overview of blockchain architecture and the role of cryptographic techniques such as digital signature schemes in securing transactions and validating identities.
Learners will also study state machine replication and understand how distributed systems maintain consistency across multiple nodes. A major focus of the course is Byzantine fault tolerance and classical consensus algorithms, which are critical for modern blockchain systems like Bitcoin and Ethereum. Through step-by-step lectures, participants will examine assumptions used in distributed computing, Byzantine broadcast protocols, and methods for achieving secure consensus in adversarial environments.
By the end of the course, students will gain a strong understanding of blockchain infrastructure, decentralized consensus, and the mathematical principles behind secure distributed systems. This course is ideal for computer science students, blockchain developers, cybersecurity enthusiasts, and anyone interested in decentralized technologies and W
