ChromaWay’s Relational Blockchain Nebula aims to power the future of the European Union

The Swedish based company is one of five remaining contractors advancing in the European Blockchain Pre-Commercial Procurement

This procurement is comparing different blockchain solutions to test which ones could bring the most promising improvements to future versions of the European Blockchain Services Infrastructure (EBSI). The EBSI initiative was established by the European Blockchain Partnership - a cooperation between EU Member States, some countries from the European Economic Area, and the European Commission – to implement cross-border services using blockchain technologies. The objective of the PCP  is to provide solutions that can “go significantly further than what is offered by existing solutions” in terms of scalability and throughput, interoperability with other blockchains, security, robustness, high sustainability, energy efficiency, and continuity of service.“

“Our Relational Blockchain Nebula, or RBN, is the culmination of several years of enterprise blockchain experience. We are confident in our ability to deliver the technology that can power the ongoing transition to a future that is more efficient, transparent, and decentralized.” - Henrik Hjelte, CEO of ChromaWay and Chromia.

One of the key use cases being proposed for the tender is “Digital Product Passport”, a blockchain-based solution to track products through their entire lifecycle, from the time of manufacture over the point of delivery to the point of reuse, recycling, or disposal. The pharma industry is one possible beneficiary of these Passports, but they could be used in numerous other cases including fashion, jewelry, and fine art. In efforts to contribute to sustainability, ChromaWay is also developing a “reversed” supply chain solution to contribute to the management of materials and ensuring that resource cycles are closed.

The European Blockchain Pre-Commercial Procurement tender is currently in Phase 2A (prototype development and lab testing) which will continue until mid-2022 after which the number of contractors will be narrowed again prior to the beginning of Phase 2B (final solution development and field testing). Over the coming months, ChromaWay will be publishing a series of articles describing the advantages and use cases of Relational Blockchain Nebula.
