KNN-Based Consensus Algorithm for Better Service Level Agreement in Blockchain as a Service (BaaS) Systems

With services in cloud manufacturing expanding, manufacturers increasingly use service level agreements (SLAs) to guarantee business processing cooperation between CSPs and CSCs (cloud providers consumers). Although blockchain smart contract technologies are critical innovations computing, consensus algorithms Blockchain as a Service (BaaS) systems often overlook the importance of SLAs. In fact, SLAs play crucial role establishing clear commitments provider customer. There currently no effective that can monitor SLA provide priority. To address this issue, we propose novel KNN-based algorithm classifies transactions based on their Any factor impacts priority transaction be used calculate distance KNN algorithm, including definition, type, CSC account type. This paper demonstrates full functionality enhanced algorithm. new method, CSP BaaS improved CSC. Experimental results obtained by adopting show is better satisfied systems.
