This module introduces blockchain, a technology which tracks the exchange of assets in a business network through the permanent storage of transaction records in a shared, distributed digital ledger. Blockchain technology increases trust, security, transparency and the traceability of data shared across a business network. Blockchain has the potential to revolutionise the way we conduct business and therefore understanding the basic concepts of blockchain will help you make smarter investments and capitalise on the potential of blockchain technology.
This module is suitable for a wide range of candidates; for example, non-technical professionals who wish to build and demonstrate an understanding of blockchain technology, facilitating engagement with their technical colleagues or their suppliers, or students who wish to add general technical knowledge to sector-specific or general studies.
