Chainalysis proposes to launch an on-chain tracking standard system, introducing "Address Clustering Ontology" to unify blockchain forensics methods

Odaily reported that blockchain analysis firm Chainalysis has released a new methodology proposal, aiming to establish a unified on-chain fund tracking standard framework for law enforcement agencies and investigators to identify address clusters and determine their possible control relationships.

The proposal defines the on-chain analysis structure in the form of an "ontology". The core is to systematically deconstruct the currently industry-wide non-standardized concept of "clusters" by dividing them into wallet segments and functional roles, and describing on-chain relationships through a two-tier structure: the first layer defines the transaction graph structure, and the second layer evaluates the inference confidence level.

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

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