中文摘要: |
本文基于轻量级区块链节点概念,提出一种新的数字电影放映系统服务框架,利用轻量级区块链节点易维护和运行的特点,在具有嵌入式系统的数字电影放映设备上部署轻节点。该节点设备由完整节点提供服务,不参与高能耗共识运算,仅承担交易发起和部分区块账本存储的功能。应用部署通过轻节点层、全节点层、区块链功能层、服务层以及应用层的划分实现可信服务。实施场景则以数字电影放映管理中的放映机节点需求为例,设计了区块链轻节点放映机功能和工作流程,并采用树莓派实现了一个原型demo 系统。 |
英文摘要: |
A new Digital movie projection system service framework is proposed based on the light blockchain node, which has the character of easy maintenance and operation, and can be deployed on digital projector with embedded CPU. The light node served by the full node, does not participate in the high-consumption consensus operation, while only take part in transaction initiation and partial block book storage. For the application and deployment with different devices, the trusted services are realized through the layers of the light node, the full node, the blockchain function, the service, and the application. Based on this structure, a prototype demo system for the management of digital movie playing is designed, with the details of the functions and workflow of the projector worked as a blockchain light node. |
