数字教育资源流动和共享是教育开放的重要基础，但是因其自身的特殊性和当前流通机制不健全等因素，使得数字教育资源流动和共享进展缓慢。文章通过对区块链技术的研究，设计了一种开放的、去中心化的资源流通模式，即双区块链结合智能合约的模式。在该模式下，通过数字资源注册链管理流通对象、业务控制由智能合约自动完成、流通账本由流通信息链进行管理，以构建一种开放的、资源自增长、自我管理的流通系统。该系统既能促进数字资源在供需双方之间的流转，又能保护资源提供者的合法权益，还能实现对流通资源的管理和监控。
【英文摘要】：
The flow and sharing of digital educational resources is an important foundation for education opening. However, limited by its characteristics and imperfect circulation mechanism, the flow and sharing of digital educational resources are slow. Based on the research of block chain technology, this paper designs an open and decentralized resource circulation model, that is, a double block chain combined with smart contract. In this model, the circulation object is supervised by digital resource registration chain, business control is automatically completed by smart contract and the transaction accounts are managed by trade information chain. In this way, an open, self-growing and self-managed circulation system can be built. The system can not only promote the circulation of digital resources between the supplier and the buyer, but also protect the legitimate rights and interests of the resource providers, and realize the management and monitoring of transaction resources as well.
