Blockchain Demystified

This course breaks down complex blockchain concepts into digestible modules, guiding learners from the foundational principles to practical coding with Solidity, Hyperledger Composer, and Go (Golang). With quizzes for every module, hands-on coding practice, and a capstone assignment, students will graduate with conceptual understanding and real-world blockchain coding experience.

Module 1: Blockchain Fundamentals—This module includes the most essential blockchain terms and terminologies that form the foundation, smart contracts and how they automate trust without intermediaries, how blockchain is driving digital transformation across industries, and the future of blockchain.

Module 2: Blockchain Principles—This module includes blockchain basics, breaking down how this innovation came to life, distributed ledger technology that keeps everyone on the same page, cryptographic applications for security and privacy, hash functions, the digital DNA of every block, digital signatures, which verify and authenticate actions, and consensus algorithms, the heart of decentralized agreement.

Module 3: Distributed Ledger Technology (DLT) —This module includes types of DLTs, how each works in unique ways, and the working principles that make secure, peer-to-peer record-keeping possible.

Module 4: Cryptographic Principles in Blockchain—This module explores the meaning of cryptography and its importance in blockchain technology, the principle of wallet operation in storing digital assets safely, the evolution of cryptocurrency and its role in blockchain economies, the story of Bitcoin, the pioneer that started it all, and getting to know the miners, the digital workers who keep blockchains running.

Module 5: Hashing in Blockchain—This module explains how cryptographic hashing principles create secure, irreversible digital fingerprints and the concept of  Merkle Trees. This robust data structure makes blockchain efficient and scalable.

Module 6: Digital Signatures—This module highlights the properties of digital signatures, what makes them secure and reliable, how transactions are signed to ensure authenticity and ownership, and uncovers the working principle behind digital signatures in blockchain systems.

Module 7: Consensus—This module explores the key properties that make consensus mechanisms resilient and trustworthy, and the types of consensus, from Proof of Work to Proof of Stake, and beyond.

Module 8: Hands-on Practical Sessions on Solidity, Hyperledger Composer, and Go. This module starts by diving into Solidity programming, the essential language for writing smart contracts on Ethereum, installation and development of blockchain using Hyperledger Composer, a powerful tool for building blockchain business networks, and finally, exploring Go language programming, one of the core languages behind enterprise-grade blockchains like Hyperledger Fabric.

In addition, each module has quizzes and coding assignments. At the end, there is a course completion assignment.
