In recent years, several initiatives have been started to investigate the potential use of distributed ledger, also known as blockchain, technologies in metrology. Proposed applications range from making traceability in calibration hierarchies more transparent and efficient to distributed infrastructures for processes in the quality infrastructure.
The 
IMEKO TC6 "Digitalisation" and the OIML "Digitalisation Task Group" jointly organized an online seminar on this topic on 29th March 2023 11 - 14 UTC.
The aim is to bring together experts and interested colleagues from metrology, legal metrology and the general quality infrastructure for an exchange and discussion on this topic. It is also intend to take this webinar as a starting point for a regular exchange aiming for a harmonization and interoperability of developments in the long run.
The seminar contained the following presentations
- PTB, Germany: From the European Metrology Cloud to an international QI Cloud
- Random Red, Croatia: Metroracle - Digital Traceability Pyramid and Measuring Device as Blockchain Oracle
- EBSI, European Commission: pan-European SSI/digital identity
- NMI-A, Australia: National blockchain development initiative for legal metrology
- NPL, United Kingdom: Blockchain applications in metrology and advanced manufacturing
- EUROLAB, International: Blockchain technologies for laboratories
