This course introduces the essential building blocks of blockchain technology, focusing on how data is structured, secured, and validated in decentralized systems. Students will begin by understanding blockchain as a new paradigm for data management, where information is stored in linked blocks that ensure transparency and immutability.
The course explains cryptographic foundations, including hashing techniques that protect data integrity and make blockchain systems secure against tampering. Learners will also explore how blocks are connected using pointers and how proof-of-work mechanisms help maintain consensus across distributed networks. These concepts form the backbone of many modern blockchain systems.
In addition, the course covers cryptocurrency transaction costs and fee optimization, helping learners understand how blockchain networks manage congestion and prioritize transactions. Participants will also study decentralized security models and common network attacks, gaining insight into how blockchain systems defend against malicious behavior and maintain trust without central authority.
By the end of the course, students will have a solid understanding of blockchain architecture, cryptography, consensus mechanisms, and network security principles. This course is ideal for beginners, developers, database enthusiasts, and anyone intere
