Chain hopping involves moving between blockchains to make tracing harder, often exploiting regulatory gaps.

A 51% attack refers to a situation where a single miner or group controls more than 50% of the blockchain network’s computational (hashing) power. This majority control allows them to manipulate the blockchain ledger by double-spending or blocking transactions.

This term is widely recognized in blockchain security contexts and is referenced in typology papers on crypto financial crime risks, including those issued by UAE authorities and FATF.

Supporting extracts:

DFSA AML thematic reviews mention the risk of manipulation and double spending in blockchains susceptible to 51% attacks.

Typology reports on cryptoasset risks highlight computational power concentration as a core vulnerability.

“51% refers to the percentage of total mining power or computational power in the network” is the standard definition across crypto AML/CFT frameworks【31.92._TFS_Typology_Paper_Eng__4.pdf; AMLCFT_Guidance_for_FIs.pdf】.

Thus,Cis correct.

Ransomware schemes are categorized as cyber-enabled financial crimes. AML/CFT frameworks require that such risks be assessed and mitigated through blockchain analytics, sanctions screening, and transaction monitoring for known ransomware wallet addresses.

Money laundering risk increases if the business operates in or near high-risk jurisdictions (D) or regions associated with narcotics production (C), as these are common sources of illicit funds.

An increase in volume and users (A) or supporting various cryptoassets (B) alone does not necessarily increase ML risk. Recent licensing (E) may indicate regulatory compliance, potentially lowering risk.

Layering involves creating complex transaction chains to disguise the illicit origin of funds. In crypto, this may involve multiple wallet hops, cross-chain swaps, and the use of privacy-enhancing technologies.

Standard due diligence typically involves reviewing negative news and verifying beneficial ownership to understand the customer’s background and potential risk factors.

Dark web forums (B) and blockchain exposure (D) are more advanced or enhanced due diligence techniques, used when higher risk is identified.

Mining generates new cryptoassets (A) by rewarding miners for solving complex cryptographic puzzles. It also validates transactions on the blockchain (D) by confirming and recording them in blocks, ensuring the integrity of the ledger.

While mining indirectly contributes to network security, the core security mechanisms involve consensus protocols beyond mining alone (B). Optimizing network functionality (C) is usually a development task rather than a mining function.

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.

Red flags related to anonymity include transactions where virtual assets are cashed out at exchanges from peer-to-peer hosted wallets with no clear business rationale. Such behavior indicates attempts to obscure the origin or destination of funds, characteristic of laundering activities.

Executing high-value transactions after inactivity (A) or frequent transfers to known VASPs (C) may be suspicious but are less directly linked to anonymity. Exchanging at a loss (D) is a different type of red flag.

FATF’s red flag indicators list (2021) highlights (B) as a key sign of anonymity-related risk.

Funds moving through multiple intermediary wallets before arriving at the client’s wallet indicate layering techniques used to obscure the source of funds, a classic money laundering tactic.

Transferring funds quickly (A) or declaring wealth (B) are less definitive indicators. An untraceable IP (C) raises concerns but is less conclusive than complex transactional layering.
