BEAT: Blockchain-Enabled Accountable and Transparent Network Sharing in 6G.
TLDR
This work presents BEAT, an automated, transparent, and accountable end-to-end architecture for network sharing based on blockchain and smart contracts, due to its permissioned nature allowing for industry-compliant SLAs with stringent governance.Abstract:
Infrastructure sharing is a widely discussed and implemented approach and is successfully adopted in telecommunications networks today. In practice, it is implemented through prior negotiated Service Level Agreements (SLAs) between the parties involved. However, it is recognised that these agreements are difficult to negotiate, monitor and enforce. For future 6G networks, resource and infrastructure sharing is expected to play an even greater role. It will be a crucial technique for reducing overall infrastructure costs and increasing operational efficiencies for operators. More efficient SLA mechanisms are thus crucial to the success of future networks.
In this work, we present "BEAT", an automated, transparent and accountable end-to-end architecture for network sharing based on blockchain and smart contracts. This work focuses on a particular type of blockchain, Permissioned Distributed Ledger (PDL), due to its permissioned nature allowing for industry-compliant SLAs with stringent governance. Our architecture can be implemented with minimal hardware changes and with minimal overheads.read more

Blockchain-based SLA Management for Inter-Provider Agreements
TL;DR: In this article , a use case of a smart contract-based inter-provider agreement is considered, and novel solutions like IOTA Tangle to perform transactions, IPFS to store the hash of use case data files, and chainlink to access off-chain data feeds for SLA monitoring, reducing costs and increasing transparency.

From network sharing to multi-tenancy: The 5G network slice broker
TL;DR: The concept of the 5G Network Slice Broker in 5G systems is introduced, which enables mobile virtual network operators, over-the-top providers, and industry vertical market players to request and lease resources from infrastructure providers dynamically via signaling means.
PBFT vs proof-of-authority: applying the CAP theorem to permissioned blockchain
Stefano De Angelis,Leonardo Aniello,Roberto Baldoni,Federico Lombardi,Andrea Margheri,Vladimiro Sassone +5 more
TL;DR: The analysis advocates that PoA for per- missioned blockchains, deployed over the Internet with Byzantine nodes, do not provide adequate consistency guarantees for scenarios where data integrity is essential, and claims that PBFT can fit better such scenarios, despite a limited loss in terms of performance.
