nChain is proud to have participated in the Blockchain Challenge Fund by Blockchain Connected. Our Senior Strategy Manager, Jack Davies, recently gave an interview at Wales Tech Week joined by Celsa Steel UK, where he shed light on our joint project. The challenge fund, funded by Welsh Government, aims to unite different projects working in the sector and unlock the full potential of blockchain technology.

‘Closing the Loop’

During the panel discussion with Celsa Steel, Jack described how the ‘Closing the Loop’ project makes the case for blockchain in bolstering both Celsa and the broader steel supply chain’s transition towards a circular economy. Through innovative data sharing technology, Jack explained how the Closing the Loop project demonstrates the real-life use cases offered by digital product passport schemes.

The blockchain-based proof of concept offers new layers of data integrity, transparency, and traceability, and its adoption could be instrumental in mitigating the unforeseen economic costs that often plague global steel supply chains.

Eoin Bailey, Innovation Manager at Celsa Steel UK, said during the panel discussion;

“….with this project, we were trying to understand how blockchain could be utilised as a form of traceability, not only through the process of scrap to steel production, but also to measure levels of engagement throughout the construction sector…”


At the core of our collaborative efforts is the empowerment of companies to further their traceability and sustainability. Jack explained that by facilitating widespread data capture and seamless sharing throughout the supply chain, our project can both quantify and magnify the benefits and value of embracing the circular economy.

During the discussion, Jack commented:

“We wanted to talk to Eoin and the whole Celsa team to understand the challenge they were facing from a fundamental perspective. We then looked at how the technology would apply to solve those challenges as a real-world use case.”

This collaboration between nChain and Celsa is creating a transformative impact on the steel industry’s sustainable trajectory.
