Question 22

Multimedia aspects of distributed ledger technologies and e-services

(Continuation of Question 22/16)

Motivation


A distributed ledger is a type of ledger that is shared, replicated, and synchronized in a distributed and decentralized manner. 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 processing and storing the management of transactions, events and records immutably in a decentralized fashion. DLT has a great potential to enhance the trustworthiness of e-services and applications in a broad area of digitalization of society, including but not limited to digital identity management, financial transaction processing, government issued document provenance, international telecommunication settlements, copyright management of multimedia content, food traceability, and voting.

Currently, a range of standardization-related and industry initiatives have commenced across the globe examining different aspects of DLT. Various activities, including exploratory workshops and cross-industry collaboration initiatives, have served as forums for discussion of potential technical challenges around the widespread adoption of DLT.

ITU-T SG16 is a leading group of e-services standardization. This Question is the dedicate group under SG16 to conduct DLT standards related study and to develop Recommendations on DLT and DLT based e-services.
