摘要:

近年来关于区块链的研究得到极大关注,然而基于 TCP/IP 的通信对这种大量数据内容广播模式的支撑并不充分。基于命名数据网络,设计全新的支持区块链推送服务的节点模型和特殊的读写表过程,提出完善的信息传输机制,通过请求聚合和数据缓存减少网内冗余流量并加速通信传输。同时给出基于本架构的虚拟货币应用实例,并通过仿真验证本方案性能的优势,进一步展望未来相关的研究方向。

Abstract:

Recent researches on blockchain have been greatly concerned by academia and industry,while the communication based on TCP/IP protocol was not enough for broadcasting a large volume of data in blockchain technology.Therefore,a novel node model supporting push service for blockchain technology and a special procedure reading-writing the table of the node model were designed based on the named-data networking,which was a distributed network architecture supporting data transmission naturally.And then the information transmission architecture of blockchain technology via named-data networking was proposed.With the aggregation of the requests and data caching,this architecture could reduce the traffic redundancy and accelerate the communication speed.Meanwhile,a use case of bitcoin based on the proposed architecture was given,in order to better understand the architecture.A numerical simulation was used to verify the performance advantages of the proposed scheme.In addition,some related future research directions were presented.

Key words: named-data networking, blockchain, information pushing, content broadcasting
