Blockchain technology has revolutionized how digital transactions, financial systems, and decentralized applications operate. Originally introduced as the foundation of Bitcoin, blockchain has evolved into a powerful technology used across industries such as finance, supply chain, healthcare, and digital identity systems.

This course introduces learners to the fundamental concepts of blockchain technology, including distributed ledgers, cryptographic hashing, consensus mechanisms, and decentralized networks. Students will learn how blockchain enables trustless systems where transactions can be verified without centralized authorities.

Through conceptual explanations and real-world examples, learners will understand how blocks are created, how transactions are validated, and how blockchain networks maintain security and transparency.

By the end of this course, students will have a strong understanding of blockchain architecture and will be ready to explore advanced topics such as smart contracts, Ethereum development, and decentralized applications (DApps).
