Smart-Contract-based System Operations Execution Method for Permissioned Blockchain Systems
Tatsuya Sato (Hitachi) ICM2017-48 LOIS2017-64
Abstract (in Japanese) (See Japanese page) 
(in English) Enterprises have paid attention to permissioned blockchain (BC) characterized with smart-contract, where business transactions among inter-authorized companies (forming consortium) can automatically be executed based on distributed consensus protocol over business logics pre-defined with program codes. A single BC system will be built across multiple management domains having different operational policies, e.g., data center of each organization; this will trigger a problem that its system operations (e.g., backup) will become costly due to the difficulty in unifying and/or adjusting operational policy, schedule, etc., among management domains. Toward solving the problem, we propose an operations execution method for BC systems; a primary idea is to define operations as smart-contract so that unified and synchronized cross-organizational operations can be executed effectively by using BC-native features. We verify the technical feasibility of the method through preliminary implementation, and validate the effectiveness of the proposed method by functional comparison to alternatives as well as estimation on operational cost reduction.
