About the course
What Is a Blockchain?
A blockchain is a distributed database or ledger that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralised record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.
One key difference between a typical database and a blockchain is how the data is structured. A blockchain collects information together in groups, known as blocks, that hold sets of information. Blocks have certain storage capacities and, when filled, are closed and linked to the previously filled block, forming a chain of data known as the blockchain. All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled.
A database usually structures its data into tables, whereas a blockchain, as its name implies, structures its data into chunks (blocks) that are strung together. This data structure inherently makes an irreversible timeline of data when implemented in a decentralized nature. When a block is filled, it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact timestamp when it is added to the chain.

What will I need?
All applicants must have an initial assessment and interview to confirm that the course is suitable for them.
Please be prepared to provide your residency documents such as a passport, EU citizen ID card, UK Birth Certificate or Biometric Card. If you have been in the UK for less than 3 years or have entered the UK with a visa you will need to provide evidence that you are eligible to study in the UK – your visa, your biometric card that covers the duration of your course or any relevant home office documents to support your residency should all be provided. If you’re an EU, EEA or Swiss citizen we will need to see evidence of ‘Pre-Settled’ or ‘Settled-status’ documents. Also for funding purposes we would need to see evidence of payslips if working (within the last 3 months). If you are receiving benefits (e.g JSA, ESA, Universal Credit (UC), Housing benefits etc. please provide evidence of this).
