Abstract

ISO 22739:2020 establishes the definitive terminology for the blockchain and distributed ledger technology (DLT) domain. In an industry characterized by rapidly evolving jargon and often conflicting definitions, this standard provides a consolidated, consensus-based glossary. It covers fundamental concepts, ranging from basic ledger types and cryptographic primitives to complex architectural roles and governance models. By defining terms with precision, the standard enables more effective communication between technical engineers, legal professionals, and policy analysts. This document is essential for organizations seeking to align their internal documentation with internationally recognized standards, reducing ambiguity in technical specifications and contractual agreements. It serves as the primary reference point for other ISO standards in the DLT family, ensuring that subsequent frameworks build upon a consistent linguistic foundation. The document acts as an authoritative stabilizer in a space often prone to marketing-driven hyperbole, grounding participants in accurate, shared definitions that promote clarity in design and implementation of DLT-based solutions.

Key findings

  • Provides a definitive, industry-standard set of definitions for DLT terminology.
  • Reduces technical ambiguity by standardizing terms like ‘consensus’, ‘ledger’, and ‘node’.
  • Acts as the cornerstone for the entire ISO/TC 307 series of blockchain standards.
  • Standardizes communication across professional fields, from legal to technical development.
