摘要

Distributed ledger technology is shifting from niche experimentation to critical infrastructure across finance, healthcare, and public administration, yet the evaluation of its non-functional quality remains an unresolved challenge. A systematic review shows that critical attributes—decentralised governance, regulatory and ethical compliance, fairness, and socio-technical trust—lie beyond the scope of ISO/IEC 25010. This work proposes an extension, ISO/IEC 25010 + BQ, which adds the characteristics Decentralisation & Governance and Regulatory & Ethical Compliance together with a cross-cutting Trust dimension. Indicative metrics and a stepwise assessment workflow are provided. The extended model affords practitioners a structured basis for specifying, evaluating, and certifying blockchain quality.
