Chainalysis has released the paper *An Ontology for Accountability*, proposing a framework for blockchain analysis data quality and evidence standards. The goal is to establish unified data quality and accountability standards for the industry. The framework divides blockchain analysis into two levels: on-chain structure analysis and entity attribution analysis, with distinct evidence standards defined for each. This aims to reduce the risk of misjudgment and enhance transparency and credibility in enforcement, compliance, and judicial scenarios. Chainalysis hopes this will drive the industry toward more unified analysis standards. https://(wublock123.com)/news/chainalysis-blockchain-data-quality-standards-framework-63677
