Question 22

Distributed ledger technologies and e-services

(New Question)


A distributed ledger is a consensus of replicated, shared, and synchronized digital data geographically spread across multiple sites, countries, or institutions. There is no central administrator or centralized data storage.
Distributed ledger technologies (DLT) are secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a DLT system. This makes DLT potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, documenting provenance, food traceability, and voting. 

A range of standardisation-related and industry initiatives have commenced across the globe examining different aspects of DLT/Blockchain. Various activities, including exploratory workshops and cross-industry collaboration initiatives, such as the Hyperledger project have served as forums for discussion of potential technical challenges around the widespread adoption of DLT.

An ITU-T Focus Group on Application of Distributed Ledger Technology (FG DLT), was established May 2017 under the auspices of TSAG. The focus group addresses a number of topics of DLT, for example, use-cases and applications, requirements for the implementation, regulatory and policy aspects, security and privacy aspects, among many other aspects.

ISO/TC 307 develops standards on DLT/Blockchain based on the market need.

ITU-T SG16 is a leading group of e-services and multimedia applications. DLT technology has a good potential of new technology and multimedia applications that needs trusted infrastructure. SG16 does not have the explicit group to discuss the above problems.

This Question develops Recommendations on Distributed Ledger Technologies and DLT based e-services.
