II. BLOCKCHAIN TRANSACTION ANALYSIS TECHNIQUES
A. Address Clustering
Address clustering is a core approach in cryptocurrency transaction analysis that includes the grouping of many addresses to detect common ownership or links. It is especially beneficial in instances when the genuine identities behind blockchain addresses need to be exposed or while seeking to follow the movement of assets across the blockchain.
Address clustering is often achieved by examining the patterns and behaviors of blockchain addresses. Addresses that are associated with a single user or entity commonly communicate with one another. By evaluating the similarities in these conversations such as common inputs in actions, timing, and transaction history, it is feasible to group addresses that are presumably controlled by the same person.
Anti-Money Laundering (AML): Address clustering is essential to AML operations as it aids financial institutions and regulatory agencies in identifying people or organizations engaged in money laundering schemes by following the flow of cash via blockchain transactions.
Cryptocurrency Forensics: In situations of fraud, theft, or unlawful actions involving cryptocurrency, address clustering may be utilized to track and identify the culprits.
Regulatory Compliance: Many countries require bitcoin service providers to retain records of the persons engaged in transactions. Address clustering assists in complying with these requirements by mapping the real persons behind blockchain addresses.
B. Transaction Graph Analysis
Transaction graph analysis is a method that visualizes the movement of assets via a blockchain by portraying addresses as nodes and transactions as edges in a graph. This graphical depiction helps researchers to acquire insights about transaction patterns and linkages among addresses.
Transaction graph analysis entails generating a graph where every address is a node, and every transaction among addresses is an edge. By evaluating the structure including the behavior of this network, researchers may find clusters of connected addresses, the course of asset transfer, and possibly suspicious or odd patterns of transactions. Tools like graph psychology and network analysis are applied to examine these graphs.
Forensic Investigations: Transaction graph analysis is important in forensic investigations to follow the flow of assets, uncover fraudulent schemes, and determine the origin and destination of monies engaged in unlawful actions.
Fraud Detection: It is utilized by digital currency exchanges and banks to identify fraudulent or suspicious activity, including Ponzi schemes, by displaying and evaluating transaction data.
Regulatory Compliance: In regulated businesses, particularly those dealing with cryptocurrencies, transaction analysis of graphs helps organizations deal with Know Your Client ( KYC ) and AML standards by spotting odd or high-risk transaction patterns.
These two approaches, address clustering and transaction graph analysis, serve crucial roles in blockchain transaction analysis, providing a better understanding of transaction flows and assisting in applications like AML, identification of fraud, and compliance. They are crucial tools for ensuring the safety and soundness of blockchain-based systems in an age when the use of blockchain is becoming more prominent in numerous sectors.
III. CHALLENGES IN BLOCKCHAIN TRANSACTION ANALYSIS
Blockchain transaction analysis, although a valuable tool for numerous applications, is not without its problems.
