解决联盟链CAP三难困境的专利族及其应用 The patent family represented by the Parallel Proof of Vote
项目简介
以并行投票证明（PPoV 中国授权号ZL202010801993.8）共识算法为代表的解决联盟链CAP三难困境的专利族是大规模高效能联盟链共识技术。单链网络管理日志下PPoV共识的吞吐量达到30万TPS，支持至少17个共识节点。对标目前国际上效率最优的Hotstuff共识算法，PPoV共识不仅不低于其吞吐量性能水平，而且交易确认时延仅为Hotstuff的1/2。 单链金融交易场下，自主研发的联盟链底层平台PPoV_Blockchain单链TPS均达3万以上，且始终保持零错误运行，远高于主流的超级账本、FISCO BCOS、Libra等联盟链项目。
项目首次提出由成百上千个单链组成统一联盟链的树形架构，可以具备亿级的的TPS，支持数字货币的全球零售应用，获得授权中国专利ZL201780003416.0“一种多层级区块链系统之间索引与链拓扑结构的维护方法”。
项目首次提出并设计基于多维超立方体的层次化递归拓扑结构，具有更低的分区容忍概率和平均最小修复时间，并能有效地拟合上层协议，从而将解决联盟链场景下的CAP三难困境变成可能。PCT专利“PCT/CN2019/075547一种联盟链共识下满足分区容忍性的拓扑构造方法及系统”已经进入中国申请阶段。
项目致力于拓宽PPoV与其它领先技术融合的边界，目前已授权以PPoV为核心的8项美国专利和5项中国发明专利，涵盖标识域名管理、网络管理、网络安全量化分析、网络控制传输、分布式存储及编码、分组交换等多个领域。
Project Brief
The patent family represented by the Parallel Proof of Vote (PPoV, China Patent Granted No. ZL202010801993.8) consensus algorithm to solve the CAP trilemma for consortium blockchains is a large-scale high-performance blockchain technology proposed.
Under single chain scenario of network management, the throughput of PPoV consensus reaches 300,000 TPS and supports at least 17 consensus nodes. Compared with the most efficient Hotstuff consensus algorithm in the world, PPoV consensus not only at least meets the throughput performance, but also reduces the transaction confirmation delay to only 50% of Hotstuff. We have independently developed PPoV_Blockchain, the underlying platform of consortium blockchain.
In the scenario of single-chain financial application, its has reached 30,000 TPS and has always run with zero errors, far higher than mainstream consortium blockchain projects such as Hyperledger Fabric, FISCO BCOS and Libra.
The project invented a multi-layer tree architecture for the first time in the world, which was consisted by hundreds or thousands of single chain to an unified consortium chain, and could reach hundreds of millions TPS and support the global retail application of digital currency. The Chinese patent was granted by “ZL201780003416.0： A Maintenance Method of Index and Chain Topology between Multi-layer Blockchain Systems".
The project was the first to propose and design a hierarchical recursive topology based on n-dimensional hypercubes with lower partition tolerance probability and average minimum repair time. It can effectively fit the upper layer protocol, so as to solve the CAP trilemma of consortium chain. PCT/CN2019/075547 "A Topology Construction Method and System Satisfying Partition Tolerance under Consortium Chain Consensus" has entered the application stage in China.
The project is committed to the integration of PPoV with other leading technologies. At present, we have authorized 8 US patents and 5 Chinese invention patents with PPoV as the core patents, covering domain name management, network management, quantitative analysis of network security, network control transmission, distributed storage system and coding, packet switching and other fields.
典型应用
项目在国际上首先提出了基于区块链技术、融合未来网络与IP的多标识网络体系MIN，突破了IP困境，实现了网络空间的多边共管。MIN具有多层次的应用场景，包括高安全专网、工业互联网、天地一体化网络、网空联合国等。MIN在2019年入选第六届世界互联网大会领先科技成果。目前，项目组建了全球MIN测试床，在全球部署了200余个顶级节点，进行全生命周期的网络管 理试验并取得成功。
Typical Application
In the world, the project first proposed MIN(Multi-Identifier Network), a network architecture based on blockchain technology and integrating future network arch. and IP , which broke through the dilemma of IP and realized multilateral co-management of cyberspace. MIN has multi-scale application scenarios, including high security private network as small scale, industrial Internet or Vehicle network as middle scale, integrated spaceterrestrial network and the Cyberspace of United Nations（CoUN） as large scale, etc. MIN was elected by the sixth World Internet Conference as leading scientific and technological achievements in 2019. At present, the project has established a global MIN test-bed and deployed more than 200 top nodes around the world to carry out the network identity management testing for full cycle, and the current proto-type is successful.
