A recent study has presented a novel privacy-enabled hybrid blockchain framework aimed at improving the security and flexibility of inter-provider agreements within 6G networks. As the telecommunications sector progresses toward next-generation 6G technology, there is an increasing need for dynamic and reliable mechanisms to manage collaborations among multiple service providers. This research meets those needs by proposing an innovative solution that utilizes blockchain technology to create secure, decentralized agreements while ensuring privacy preservation. The proposed framework uniquely integrates both public and private transaction workflows, implemented via the Hyperledger Besu platform, a respected enterprise blockchain solution noted for its modularity and adherence to Ethereum standards. This combination enables a flexible system where service registration, selection, and monitoring are decentralized and transparent, yet sensitive information is safeguarded through privacy-preserving techniques. At the core of the framework are role-based smart contracts that regulate interactions and enforce Service Level Agreements (SLAs). These contracts automate many aspects of provider agreements, including detecting and reporting SLA breaches, which is essential for maintaining trust and accountability among participants. To further bolster privacy, the system employs privacy groups, allowing private transactions between specified participants without revealing confidential data to the entire network. Extensive experimental evaluations demonstrate the framework's performance characteristics. Public blockchain interactions exhibit stable latency, showing that the system can efficiently handle open, transparent operations.

However, private transactions introduce extra overhead, mainly due to off-chain coordination required to manage privacy and data confidentiality. Despite this increased complexity, the framework effectively balances transparency with privacy, confirming its practical feasibility. These results offer valuable insights for the telecommunications industry, highlighting that privacy-enabled hybrid blockchain architectures are promising foundations for trustworthy, decentralized agreement systems in 6G networks. By facilitating both public transparency and private coordination, the framework addresses critical challenges related to collaboration among diverse providers in a highly dynamic and data-sensitive context. Given that 6G networks are anticipated to support a broad range of applications with strict performance and security demands, solutions like this hybrid blockchain framework become essential. The integration of blockchain’s inherent security features with customized privacy controls assures stakeholders that agreements are robust, verifiable, and respectful of confidentiality requirements. In conclusion, the study emphasizes the potential of hybrid blockchain technologies—particularly those leveraging platforms like Hyperledger Besu—to transform the management of inter-provider agreements in future communication networks. The framework’s architecture and evaluated performance lay the groundwork for scalable, secure, and privacy-aware SLA management systems for the 6G era. This advancement marks a significant move toward establishing decentralized, trustworthy, and adaptable ecosystems for network services.
