Chainalysis plans to launch an on-chain tracking standard system, proposing an "Address Clustering Ontology" to unify blockchain forensic methods

Odaily Odaily reports that blockchain analytics firm Chainalysis has released a new methodological proposal, aiming to establish a standardized framework for on-chain fund tracking for law enforcement agencies and investigators, used to identify address clusters and determine their possible control relationships.

The proposal defines the on-chain analysis structure in the form of an "ontology," with the core goal of systematically decomposing the currently unstandardized industry concept of "clusters." It divides them into wallet segments and functional roles, describing on-chain relationships through a two-tier structure: the first tier defines the transaction graph structure, and the second tier assesses the inference confidence level.

Chainalysis states that the framework aims to enhance the interpretability and legal applicability of on-chain forensic methods and has been designed and validated based on its practical experience in cases related to the U.S. Department of Justice, including its application in analyzing the Bitcoin Fog mixing service case. The company's Chief Scientist, Jacob Illum, pointed out that the goal of this proposal is to answer the question, "On what evidentiary basis can these addresses be considered belonging to the same entity?" However, he simultaneously emphasized that on-chain analysis alone cannot directly identify end-user identities, and must still be combined with legal investigation methods involving centralized entities like exchanges.

Chainalysis notes that this standard proposal is currently open for discussion within the industry, hoping to promote the formation of more unified technical specifications for on-chain analysis methods in the fields of law enforcement and compliance. (CoinDesk)
