Proof-of-Stake (PoS) replaces the energy-intensive mining process of Proof-of-Work by allowing validators to secure the network based on the amount of cryptocurrency they ''stake'' as collateral. Validators are rewarded for correctly validating transactions and risk losing their stake if they act dishonestly. Regulatory AML/CFT programs must consider validator concentration risks and the jurisdictional exposure of validators in PoS systems.

A token burn is the deliberate removal of tokens from circulation by sending them to an unspendable address. While sometimes legitimate, burns can also be misused for market manipulation.

FATF Recommendation 20 mandates that STRs be filed whenever there is suspicion or reasonable grounds to suspect criminal proceeds, regardless of the transaction value. This is mirrored in DFSA and FSRA AML regulations, ensuring that the reporting obligation is triggered by suspicion, not just thresholds.

FATF defines VASPs as entities that conduct one or more of the following activities:

Exchanging one or more forms of virtual assets (B),

Providing financial services related to initial coin offerings (ICOs) (C),

Exchanging virtual assets for fiat currencies or vice versa (D).

Mining operations (A) and software creation (E) are excluded from the VASP definition as they do not involve financial intermediation. Initial public offerings (IPOs) (F) pertain to traditional securities and are outside the scope of VASP activities.

This definition aligns with FATF Recommendation 15 and DFSA regulatory frameworks.

FATF defines VASPs as entities that conduct certain specified activities involving virtual assets. Licensing or registration as a VASP is required primarily for entities engaged in activities such as safekeeping and/or administration of virtual assets or conducting exchanges between one or more forms of virtual assets.

Cryptocurrency mining operations (A) and operating blockchain nodes (C) are generally excluded from the VASP definition because they do not involve handling customer funds or providing financial services. Virtual money service businesses (D) is a broader term that may include VASPs but not all such businesses fall under VASP regulations unless they meet the activity criteria.

This aligns with the DFSA AML Module and FATF Recommendation 15, which regulate entities providing virtual asset custody or exchange services to customers and require them to be licensed or registered.

A restricted blockchain is 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 that consortium blockchains allow for compliance controls, participant vetting, and transaction monitoring---making them particularly suitable for financial ecosystems where controlled access is essential.
