uBaaS: A Unified Blockchain as a Service Platform
This addresses the lack-of-trust issues in business by improving productivity for blockchain developers, though it appears incremental as it builds on existing BaaS concepts.
The paper tackles the problem of vendor-locked and expertise-intensive blockchain application development by proposing uBaaS, a unified platform that supports design and deployment, and demonstrates its feasibility and scalability in a real-world quality tracing use case.
Blockchain is an innovative distributed ledger technology which has attracted a wide range of interests for building the next generation of applications to address lack-of-trust issues in business. Blockchain as a service (BaaS) is a promising solution to improve the productivity of blockchain application development. However, existing BaaS deployment solutions are mostly vendor-locked: they are either bound to a cloud provider or a blockchain platform. In addition to deployment, design and implementation of blockchain-based applications is a hard task requiring deep expertise. Therefore, this paper presents a unified blockchain as a service platform (uBaaS) to support both design and deployment of blockchain-based applications. The services in uBaaS include deployment as a service, design pattern as a service and auxiliary services. In uBaaS, deployment as a service is platform agnostic, which can avoid lock-in to specific cloud platforms, while design pattern as a service applies design patterns for data management and smart contract design to address the scalability and security issues of blockchain. The proposed solutions are evaluated using a real-world quality tracing use case in terms of feasibility and scalability.
