Despite the advantages, the design of decentralized systems and applications introduces several challenges and open problems that span multiple layers of system architecture, for example the interoperability between platforms, a crucial issue in the emerging Internet of Blockchains model. Addressing these challenges requires advances in decentralized technologies design and implementations, in order to be able to satisfy the largest possible variety of business requirements. Well known examples include scalable data dissemination, efficient peer discovery and routing, latency-aware consensus protocols, fault tolerance under network partitions, and coordination across heterogeneous and dynamic nodes, alongside with cryptographic protocols enabling selective disclosure and fine‑grained authorization, privacy‑preserving communication, networking and storage protocols that guarantee anonymity 

The goal of this workshop is to bring together researchers and practitioners to explore novel methodologies, architectures, and protocols that advance the state of the art in decentralized systems. We aim to foster discussion on both theoretical foundations and real-world applications, highlighting use cases and case studies where decentralization can effectively address contemporary computing and societal needs.
