Objectives
- Explain the fundamental concepts of blockchain including distributed ledgers, consensus mechanisms, and cryptographic principles.
- Differentiate between types of blockchains (public, private, consortium, hybrid) and identify their use cases.
- Describe the architecture of Bitcoin and understand how transactions, wallets, mining, and forks operate.
- Compare Ethereum and Bitcoin, and explain the role of smart contracts, DApps, and gas fees in the Ethereum ecosystem.
- Write, deploy, and test smart contracts in Solidity using Remix, Ganache, and the Ethereum Virtual Machine (EVM).
- Evaluate security vulnerabilities in smart contracts (e.g., reentrancy, integer overflow) and apply mitigation techniques.
- Understand the design and architecture of Hyperledger Fabric and contrast permissioned vs. permissionless blockchains.
- Explore interoperability solutions such as Polkadot and Cosmos, and explain how different blockchain networks communicate.
- Analyze emerging trends such as Decentralized Finance (DeFi), Layer-2 scaling, and AI-blockchain integration.
- Assess blockchain security threats (51% attacks, Sybil attacks, eclipse attacks) and apply strategies for mitigation.
- Implement cryptographic techniques such as RSA signing, hashing, and zero-knowledge proofs in blockchain contexts.
- Build a simple blockchain prototype in Python, including block creation, proof-of-work, and transaction recording.
- Develop blockchain-based applications in various domains such as voting, land registry, healthcare, supply chain, and identity management.
- Apply decentralized identity and confidential transactions concepts to real-world scenarios.
- Critically evaluate regulatory and legal challenges associated with cryptocurrencies and blockchain adoption in enterprises.

FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
