    ACCA · Question 15 · Syllabus C: Business functions, regulation and technology

    HealthPlus, a healthcare service firm, is implementing a new system to track the supply chain of sensitive pharmaceuticals. They have chosen to use Blockchain technology because they need a system where, once a transaction is recorded, it cannot be altered or deleted by any single party.

    Which core characteristic of Blockchain technology provides this specific benefit?

    Answer options:

    A.

    Decentralization

    B.

    Immutability

    C.

    Transparency

    D.

    Smart Contracts

    How to approach this question

    Identify the term that means 'unable to be changed or mutated'.

    Full Answer

    B.Immutability✓ Correct
    A key feature of Blockchain is immutability. Because each block contains a cryptographic hash of the previous block, altering any historical record would require recalculating all subsequent blocks across the entire distributed network, making it practically impossible to tamper with data.

    Common mistakes

    Selecting Decentralization. While blockchains are decentralized, Immutability is the specific term for data being unalterable.
