Blockchain Technology

This intermediate-level course introduces the fundamentals of blockchain technology, distributed ledgers, smart contracts, and the Ethereum platform, with a particular focus on cybersecurity, privacy, and secure decentralised systems.

Participants explore the principles underlying blockchain networks, including distributed ledger technology, blockchain platforms, and the operation of smart contracts. The course examines blockchain security mechanisms, privacy considerations, and common attacks, helping learners understand the risks and challenges associated with decentralised applications.

Learners also gain an understanding of Ethereum accounts and transactions, the Ethereum Virtual Machine (EVM), and how smart contracts are executed. Particular attention is given to gas, transaction fees, and the block gas limit, explaining their role in the operation and efficiency of blockchain-based systems.

The course is organised into six self-paced modules, each accompanied by a knowledge assessment to reinforce understanding of the concepts presented.

By the end of the course, participants will be able to explain fundamental blockchain principles, understand how Ethereum transactions and smart contracts operate, identify key blockchain security and privacy considerations, and describe the role of gas and transaction fees in Ethereum.

This fully online course is suitable for learners interested in blockchain technology, cybersecurity, smart contracts, and emerging digital technologies.
