Chainalysis launches draft standards for blockchain tracking.

BlockBeats news, June 30 - Blockchain analysis firm Chainalysis has released a blockchain tracing ontology proposal, attempting to establish industry standards for on-chain address clustering and tracking. The document splits "cluster (address clusters)" into finer structures such as "wallet fragments," and proposes a two-layer framework: the first layer builds an address relationship graph, and the second layer annotates analysis credibility, helping law enforcement and prosecutors determine whether data can be used in cases.

Chainalysis bases its proposal on practical experience from the U.S. Department of Justice's money laundering case against Roman Sterlingov, co-founder of the Bitcoin Fog mixing service. The judge in that case ruled the company's Reactor tool "highly reliable" after a Daubert hearing. The company emphasizes that on-chain analysis alone cannot directly identify end users; it requires offline information such as court subpoenas, and calls for the industry to maintain independent review and feedback on the methodology.
