Hash immutability means that altering any transaction would require changing all subsequent blocks and achieving majority consensus. This security property underpins blockchain integrity and forensic traceability, crucial in AML investigations.

Arestricted blockchainis one where participation—either in transaction validation, data access, or both—is limited to selected entities rather than being open to the public.

Consortium blockchain (D)is a common type of restricted blockchain in which multiple pre-approved organizations collectively manage the network. It offers partial decentralization but with controlled membership, making it suitable for regulated environments such as financial services, supply chain tracking, and interbank settlements.

Other options explained:

Hybrid (A):Combines elements of public and private chains, but not necessarily “restricted” in the strict governance sense.

Public (B):Open to anyone to join, read, and write data; not restricted.

Private (C):While private blockchains are also restricted, in AML/CFT guidance, “restricted blockchain” generally refers to consortium arrangements involving multiple vetted participants, rather than a single organization’s closed chain.

Regulatory and technical literature in DIFC/ADGM contexts note thatconsortium blockchainsallow for compliance controls, participant vetting, and transaction monitoring—making them particularly suitable for financial ecosystems where controlled access is essential.

Machine learning (ML) and artificial intelligence (AI) are applied within compliance frameworks to enhance the efficiency of monitoring and detection processes and to allow skilled compliance resources to focus on higher-value activities such as complex investigations and strategic decision-making. ML/AI tools can process vast amounts of transaction data to identify suspicious patterns faster than manual processes.

They do not reduce the fundamental requirement for risk assessment (A) nor are they intended primarily to reduce headcount (C), but rather to optimize resource allocation.

AML and DFSA guidance emphasize leveraging technology to improve the effectiveness and efficiency of AML controls while maintaining robust risk management.
