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.

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.

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

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.
