A Novel Blockchain as a Service Paradigm

摘要

Blockchain brings a new vision for decentralized and trusted systems with more security, resiliency and efficiency. But the barrier of deployment is relative high and BaaS (Blockchain as a Service) emerged to meet the challenge. The current mainstream BaaS providers usually adopt APIs for user access or simply migrate blockchain application to Cloud. Obviously these BaaSs are provided in centralized way which erodes the trustless mechanism and incurs lock-in risk. This paper proposes a novel service paradigm to overcome the limitation of current BaaS. The paradigm adopts deployable components to reconstruct the open and decentralized blockchain service with corresponding long-life encapsulated blockchain service. The meta blockchain service generates dedicated easy to deploy encapsulated components to build up more parties BaaS network to guarantee decentralization, auditability and better efficiency. The encapsulated blockchain service components are the seeds of the whole blockchain system. A hyperledger based implementation demonstrates the paradigm can alleviate the erosion of characteristics of blockchain and lock-in risk caused by current BaaSs.
