Global Trends

In 2023, the trend in regulatory actions against crypto companies showed a significant increase, reflecting a global crackdown and a focus on compliance and fraud prevention. Authorities worldwide are increasingly focusing on compliance, imposing significant penalties, and pursuing criminal charges for AML failings. This trend underscores a concerted effort to combat money laundering and maintain the integrity of the financial system, particularly in the evolving crypto asset market.
The United States, in particular, emerged as a global enforcer, with significant actions taken against prominent players in the crypto market, such as Binance. The Commodity Futures Trading Commission (CFTC) also showed a marked increase in enforcement actions related to digital assets - nearly half of all CFTC actions in 2023 were related to digital assets, cementing its reputation as a premier enforcement agency in the digital asset space.

Furthermore, several entities were sanctioned by the OFAC for their involvement in AML and CFT violations.

The recent regulatory actions serve as a stark reminder of the importance of robust AML and CFT programs within the crypto industry. As regulatory scrutiny intensifies, crypto providers must proactively invest in compliance measures to ensure the compliant operations of the business. By prioritizing AML and CFT compliance, they can demonstrate their commitment to upholding regulatory standards and safeguarding the integrity of the financial system.

The message to the crypto world is loud and clear: adhering to AML and CFT rules isn't just important, it's essential.

How Blockchain Nature Enables Risk Analysis

Blockchain technology represents a seismic shift from traditional finance technology in recording transactions. At its core, blockchain is a decentralized and immutable ledger system that underpins cryptocurrencies and a myriad of digital transactions. Unlike traditional finance tech reliant on centralized governance arrangements , blockchain operates on a distributed network of nodes.
This decentralized structure ensures transparency, security, and trust among participants, as every transaction is recorded across multiple nodes in a tamper-proof manner. The hallmark of blockchain lies in its consensus mechanism, where transactions are verified and added to the chain through a consensus protocol, eliminating the need for intermediaries and fostering a peer-to-peer transaction ecosystem. This disruptive technology not only redefines the mechanics of recording transactions but also heralds a paradigm shift in how we perceive trust and decentralization within financial ecosystems.

As early as in 2018, Christine Lagarde noted that cryptocurrency’s own blockchain technology could be used to control it and highlighted that policymakers must “understand the innovative technologies, learn from them, and perhaps even adopt some of them to improve regulation, supervision, and surveillance”. JMLSG Guidance in the UK further emphasized that the “transparency and stability associated with public blockchains creates persistent, irrevocable transaction records that enable risk analysis and risk mitigation”.

It is true that blockchain's own nature enables risk analysis through its transparency, immutability, and decentralized ledger. Every transaction is recorded and traceable, allowing for a detailed examination of crypto flows and identification of suspicious activities. The immutable record ensures data integrity, while decentralization distributes data across multiple nodes, reducing the risk of fraud and tampering. This creates a reliable environment for risk analysis and regulatory compliance.
Blockchain analytics  firms leverage these unique features by analyzing the public ledger of transactions to detect patterns, trace funds, and identify potentially illicit activities or actors. These insights are crucial in developing Anti-Money Laundering (AML) and risk management solutions, as they help in understanding the flow of funds, the history of wallets, and the connections between different transactions and participants, as well as exposure to high risk actors.By providing a clear view of transactional paths, blockchain analytics tools are essential in helping organizations comply with AML regulations and combating financial crimes.

Importantly, the FATF and other global policymakers have already recognised the importance of blockchain analytics in AML compliance and effective supervision, and indicated that the tools “supported and informed successful enforcement cases, targeted financial sanctions, and other actions to disrupt ransomware-financing”.

Blockchain analytics can provide interesting insights into the use of virtual assets that are not available with traditional financial products and services. Moreover, blockchain analysis can be useful for investigative purposes to track identified illicit funds or attribute identities of wallet holders. Such tools can be of great potential benefit to law enforcement, FIUs, supervisors, VASPs and the broader private sector in fulfilling their AML/CFT obligations and combating illicit activity.

Importance of Blockchain Analytics in Compliance for Organizations

Blockchain analytics solutions employ techniques like heuristic clustering, off-chain data integration, and behavior pattern recognition to enable private sector firms to achieve robust AML compliance. The graphical mapping of transaction flows, identification of high risk entities, ongoing wallet screening, and investigation workflows powered by these tools allow companies to effectively meet regulatory requirements related to reporting suspicious activities, sanctions monitoring, risk exposure checks, and due diligence.

Blockchain analytics also serve as a crucial tool for regulators in supervising the crypto market by enabling proactive monitoring of transaction flows, overseeing entities, managing regulatory permissions, and reviewing suspicious activity reports. Supervising the compliance with regulations and guidelines issued by national authorities/regulators necessitates the implementation of robust blockchain analytics solutions to meet regulatory objectives.

Real-Time Monitoring of Transactions

Blockchain analytics facilitate real-time monitoring by leveraging advanced algorithms and data analysis tools. These tools continuously scan the blockchain, examining transactional data and patterns as new blocks are added. For instance, software solutions use techniques like clustering analysis to group transactions and identify potentially suspicious activities. By employing a combination of machine learning algorithms and data visualization techniques, organizations can gain real-time insights into transaction flows. Additionally, they can set up alerts triggered by specific criteria, enabling swift intervention upon detecting suspicious behavior.

Risk & Sanctions Analysis

Blockchain analytics solutions enable organizations to conduct detailed risk and sanctions analysis on transactions and counterparties. By leveraging labeled cluster data and wallet attribution, businesses can identify transactions linked to high-risk sources of funds such as ransomware, cybercrime, PII/carding fraud, and other criminal entities.

Tagging and monitoring tools allow analysts to detect exposure to sanctioned addresses or entities, facilitating compliance with regulations. Businesses can set risk-based triggers and thresholds tailored to their policies for closer examination when transactions interact with medium or high-risk clusters. Overall, blockchain analytics stacks allow crypto ecosystem participants to make more informed decisions by better understanding transactional risks.


Blockchain analytics aid due diligence efforts by providing a transparent ledger of transactions. Companies can employ forensic analysis tools that trace the origin and flow of funds. These tools allow for the examination of transaction histories, identifying sources of funds and verifying the legitimacy of counterparties. Moreover, smart contract auditing tools help in assessing the integrity and security of automated contracts deployed on blockchains. This meticulous examination assists businesses in ensuring compliance with regulations and mitigating risks associated with fraudulent activities or illegal transactions.

Identifying and Reporting Suspicious Activity

Blockchain analytics utilize sophisticated algorithms to identify irregularities or suspicious patterns within transaction data. Techniques such as anomaly detection and behavior analysis help in flagging transactions that deviate from established norms. Moreover, companies can integrate Know Your Transaction (KYT) tools that track the history of funds to detect potential involvement in illicit activities. Once suspicious activity is identified, businesses follow regulatory protocols to report such incidents to relevant authorities. This reporting often involves compiling comprehensive reports with detailed transactional evidence, timelines, and analysis of suspicious behavior.

Counterparty Due Diligence

The transparency of blockchains also facilitates streamlined counterparty due diligence during customer onboarding or assessments of potential partners/investments. Analytics tools that map the on-chain footprint of Virtual Asset Service Providers (VASPs) enable risk teams to analyze the compliance history, interactions, risk profile, and overall integrity of the counterparty.

By examining factors like the share of transactions with risky clusters, exposure to sanctions, suspicious activity reports (SARs) filed, and adherence to Travel Rule protocols, businesses can make informed decisions when onboarding VASPs. Ongoing monitoring helps assess whether partners/investees maintain robust controls throughout the relationship. Overall, counterparty due diligence leveraging blockchain analytics provides the transparency required for managing business relationships and regulatory obligations.


In 2023, the financial penalties and legal actions taken against crypto service providers underscored a global shift towards more stringent Anti-Money Laundering (AML) standards. The evolving regulatory landscape now necessitates the use of cutting-edge analytics tools that harness blockchain transparency for effective compliance.

Blockchain analytics are revolutionizing how businesses monitor transactions in real time, detect unusual patterns, and provide detailed records for investigative purposes. These technologies are crucial for adhering to the increasingly complex AML/Counter-Financing of Terrorism (CFT) regulations and are becoming essential for tracking cryptocurrency movements.

Companies that proactively incorporate compliant blockchain analytics into their operations will be better equipped to navigate regulatory complexities.
