Third cohort of the European Blockchain Sandbox: Priority on real-world use cases such as digital product passports and supply chain traceability; grid flexibility management and accounting for renewable energy; financial services on tokenized assets with verifiable identities and embedded EU compliance. According to the organizers, the pool includes one European Blockchain Services Infrastructure case for public organizations and nineteen additional cases representing different industries and regulatory themes across all EU/EEA regions. The selection was conducted by Warren Brandeis experts under the supervision of an independent academic panel, including Roman Beck, Soulla Louca, and Walter Blocher.
