Giving a talk with the title “Myrtus: A Computing Continuum Platform”
On 20 November 2025, MYRTUS took part in the Gaia-X Summit 2025 in Porto, Portugal, themed “Digital Ecosystems in Action”. In the Tech Theatre, Giulia Biagioni (TNO) presented “Myrtus: A Computing Continuum Platform”, the work done with her colleagues Coen van Leeuwen and Bart Driessen to bring Gaia-X and MYRTUS together.
MYRTUS orchestrates the cloud-fog-edge continuum in a sustainable and secure way. Trust is essential: users must be sure that services behave securely, that data are handled correctly and that operations comply with the European digital legislative framework. This is why MYRTUS looked at the Gaia-X Trust Framework to answer a simple question: what happens when a new organisation wants to join the continuum, and can its onboarding be checked automatically?
The talk presented a proof of concept of the MYRTUS compliance service. The service reads the Gaia-X Verifiable Presentation stored in the Kubernetes cluster of the joining organisation, verifies its signature and validity dates, and checks the embedded Verifiable Credentials against MYRTUS rules written in SHACL: for example, that the organisation is registered in an EU member state, has a valid registration number and has accepted the Gaia-X terms and conditions. It then returns a transparent verification report. Only if every check passes can the cluster be connected to the MYRTUS platform through Liqo.
A live demonstration showed the whole path, from the credential to the validation result. It also showed what happens when a rule changes: once the country of the organisation was removed from the allowed list, the signature was still valid but the SHACL check failed, and the cluster could no longer join.
In 2026 this work moved one step further, with the checks integrated into Danube, the extensible compliance framework of Gaia-X.
