Blockchain and Distributed Ledger Technologies

The sectors of Digital Twins, Virtual Worlds/Citiverse, IoT and Data Spaces are fragmented, especially the uneven uptake of NGSI‑LD, Smart Data Models/SAREF and governance models creates a barrier for cross‑domain interoperability in cities. Therefore, I focus on harmonising these layers within ITU‑T Citiverse and EU Local Digital Twin  (LDT) Toolbox. I also contribute to aligning LDT and Data Space governance with UNE 0087:2025 and the Gaia‑X Trust Framework to operationalise sovereignty, compliance and automated conformance. Moreover, I contribute to mapping LDT/MIM8, NGSI‑LD, SIMPL and Citiverse deliverables to speed deployment and avoid duplicate or conflicting specs. 
 

Standardisation in the field of Blockchain and Distributed Ledger Technologies is imperative to promote interoperability, security, and innovation across European markets. The rapid evolution of these technologies has led to a fragmented landscape of standards globally. This fragmentation presents challenges such as hindered cross-border data flow and increased compliance burdens on European businesses. My activity aims to address these critical gaps by actively participating in the creation of comprehensive, internationally recognized standards.
My engagement in the Joint ISO/TC 307 - ISO/IEC JTC 1/SC 27 WG directly supports this action. By actively participating in WG, I am bolstering Europe's representation and influence in shaping global standards in this transformative domain.
From a European perspective, this activity is pivotal. Europe seeks to not only embrace but lead in the adoption and implementation of Blockchain and Distributed Ledger Technologies. By participating in the development of standards, we ensure that Europe's interests, values, and priorities are ingrained in the foundation of these technologies. This is paramount for bolstering Europe's digital sovereignty, fostering innovation, and ensuring that European businesses remain competitive on the global stage.
 

This fellowship supports my role as a convener of ISO TCC307 WG3. The priority is to organise the appropriate ballots and meetings to allow the experts to discuss and reach a consensus based on the comments received for the projects in ISO TC 307 WG3. Another priority is to complete the norms with the attendance list and verify that all experts in the meeting were duly registered in the portal and authorised to participate in the meetings.

One of the main challenges of this work has been overcoming the cultural barriers and language differences encountered during this period, particularly through various meetings and ad hoc meetings for the three projects, which are ongoing in preparation for the final stage to publication.
