ISO/TC 307 - Blockchain and distributed ledger technologies

This document provides an overview of existing DLT systems for identity management, i.e. the mechanisms by which one or more entities can create, receive, modify, use and revoke a set of identity attributes. This document covers the following topics: — Managing identity for individuals, organizations, things (IoT & objects), functions and processes and other entities including within and across DLT systems. — Description of the actors and their interactions and common interfaces. — Architectures. — Existing relevant standards and frameworks.

This document provides guiding principles and a framework for the governance of DLT systems. The document also provides guidance on the fulfilment of governance, including risk and regulatory contexts, that supports the effective, efficient, and acceptable use of DLT systems.

This document specifies a reference architecture for Distributed Ledger Technology (DLT) systems including blockchain systems. The reference architecture addresses concepts, cross-cutting aspects, architectural considerations, and architecture views, including functional components, roles, activities, and their relationships for blockchain and DLT.

This document specifies a taxonomy and an ontology for blockchain and distributed ledger technologies (DLT). The taxonomy includes a taxonomy of concepts, a taxonomy of DLT systems and a taxonomy of application domains, purposes and economy activity sections for use cases. The ontology includes classes and attributes as well as relations between concepts. The audience includes but is not limited to academics, architects, customers, users, tool developers, regulators, auditors and standards development organizations.

This document discusses the threats, risks, and controls related to: — systems that provide digital asset custodian services and/or exchange services to their customers (consumers and businesses) and management of security when an incident occurs; — asset information (including the signature key of the digital asset) that a custodian of digital assets manages. This document is addressed to digital asset custodians that manage signature keys associated with digital asset accounts. In such a case, certain specific recommendations apply. The following is out of scope of this document: — core security controls of blockchain and DLT systems; — business risks of digital asset custodians; — segregation of customer's assets; — governance and management issues.

This document provides fundamental terminology for blockchain and distributed ledger technologies.

This document provides an overview of privacy and personally identifiable information (PII) protection as applied to blockchain and distributed ledger technologies (DLT) systems.

This document provides an overview of smart contracts in BC/DLT systems; describing what smart contracts are and how they work. It also discusses methods of interaction between multiple smart contracts. This document focuses on technical aspects of smart contracts. Smart contracts for legally binding use and applications will only be briefly mentioned in this document.
