Attachments Output – Draft new Recommendation ITU-T F.DLT-MAS “Reference architecture for data sharing and management in multi-agent multimedia systems based on distributed ledger technology"
Body 
As AI systems evolve into collaborative multi-agent multimedia systems (MAS),
seamless data exchange among heterogeneous agents has become essential.
However, fragmented vendor structures currently cause severe data silos and
hinder interoperability across different platforms. Furthermore, applying
centralized accounting to these distributed networks introduces high
integration costs. To address these challenges, Distributed ledger technology
(DLT) provides a decentralized trust layer that ensures immutable data sharing
and enables automated smart contract settlement. Consequently, this
Recommendation specifies a comprehensive DLT-based reference architecture and
framework to facilitate secure data sharing and management in multi-agent
multimedia systems.

This Recommendation provides reference architecture for data sharing and
management in multi-agent multimedia systems based on distributed ledger
technology. The scope of this Recommendation also includes:

   –    Overview of the data sharing and management in multi-agent multimedia
   systems

   –    Reference architecture in multi-agent multimedia systems based on
   distributed ledger technology

SG21 looks forward to keeping continued collaboration with you on this topic.
