A sophisticated mechanical construct featuring polished silver, translucent blue, and clear components is intricately assembled, interconnected by thin black wires. This complex device appears to be a conceptual model of a highly advanced, multi-faceted system, embodying the principles of decentralized finance DeFi

Briefing

The paper addresses the critical problem of operational complexity, manual delays, and reliance on trusted third parties in dynamic multi-domain edge system federation. It proposes a novel blockchain-based Multi-access Edge Computing (MEF) framework that leverages smart contracts to automate the entire federation lifecycle, from negotiation to deployment. This innovation enables secure, trustless, and scalable interactions between edge providers, thereby fundamentally reshaping future decentralized edge resource management.

Within its core, a luminous, fragmented blue substance appears to be actively flowing around a central metallic rod, suggesting dynamic internal processes and data movement

Context

Before this research, existing Multi-access Edge Computing (MEC) federation solutions largely relied on pre-established Service Level Agreements (SLAs) and manual configurations, suitable only for static environments. These approaches struggled with the dynamic nature of open federations, introducing significant operational overhead, delays, and a dependence on centralized intermediaries or complex, unscalable peer-to-peer agreements for managing security, privacy, and billing across diverse administrative domains.

Abstract, flowing forms in translucent white and vibrant deep blue dominate the frame, set against a dark, gradient background. The composition features smooth, overlapping layers that create a sense of depth and continuous movement, with light reflecting off the polished surfaces

Analysis

The core mechanism involves integrating a permissioned blockchain into the ETSI MEC architecture, where each MEC system operates an extended MEF component comprising a Blockchain Manager and a Blockchain Node. Federation procedures are encoded within a generic Federation Smart Contract, acting as a distributed authority that autonomously enforces federation logic and dynamic SLAs. MEC systems interact by submitting immutable transactions to this contract for service announcements, bidding, winner selection, and deployment confirmations. This fundamentally differs from previous approaches, which were static, manually-intensive, or centrally-brokered, by decentralizing control, automating negotiation and execution without prior trust, and leveraging cryptographic security for verifiable interactions.

Outlook

Future research will focus on real-world deployment of this blockchain-driven service federation framework and a comparative performance analysis with alternative blockchain platforms like Hyperledger Fabric. This theoretical advancement could unlock truly dynamic and automated resource sharing across heterogeneous edge systems, enabling novel low-latency applications and significantly streamlining multi-operator collaborations in 5G and beyond networks within the next 3-5 years. It opens new avenues for exploring decentralized autonomous organizations (DAOs) in infrastructure management and programmable network architectures.
