ZTE, Huawei, Dajiang, Kang ...... when the US resorted to blockade the banner technology, China's local enterprises have faced a challenge. As the next generation of IT chain block main battlefield, the game between the major powers China and the US has never stopped.
Due to the synchronization of the development of Sino-US chain block, the block itself is open source as well as the inherent global chain block chain technology, the United States is difficult to curb China's progress in the technical aspects of the chain block, and a block from the chain product morphological point of view, China took the lead in many areas.
US core technology startups China to date
is generally considered block chain technology is Satoshi invention, and so far, what Nakamoto Japanese, Australians or Americans still controversial, Nakamoto himself was not the technology in a national patent.
Even so, viewed from a technical perspective, the United States is the main block chain technology to create national consensus has been formed in the world. Block chain is not a technology, but rather a collection of technologies, and this set of technologies but all can be verified first invented by the Americans. Americans block chain technology has made the first move, the two countries, though not in the same starting line, but history has fully proved that China unlimited potential in science and technology creation.
In the block chain hashing algorithm core technology and distributed computing these two key areas, China's achievements enough to emulate the United States, and even overcame the global block chain technology industry a big step forward.
Hash algorithm precisely, it can not be called a algorithm, which is a cryptographic hash function family defined by the American National Standards Institute-cum-technology in one. Currently block chain commonly used hash algorithm SHA series of standards mostly designed by the Institute. Including SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, and the like. In addition, the Institute will also incorporate other standard hashing algorithm, such as SHA-3 was originally designed jointly by the European STMicroelectronics and NXP cryptographers. October 2012, the American National Standards Institute and technological chose Keccak algorithm as SHA - 3 standard algorithm, the algorithm has become the choice of many block chains.
In fact, China in hashing algorithms also have high achievements. CAS academician Wang Xiaoyun theory put forward collision attack cryptographic hash function, that is, the difference bit analysis module, increasing the probability of crack five international common hash function algorithm, including MD5, SHA-1's. And China in terms of hashing algorithm also developed their own standards, such as SM3, according to the State Cryptography Administration said its safety and efficiency and SHA-256 quite.
Research on the block chain distributed computing, Chinese technological achievements in this field is to let the world's attention.
Since 2008, the "Father of the block chain" Nakamoto published "Bitcoin: A Peer-to- Peer Electronic Cash System" So far, more than ten years, scientists around the world, technology developers waging efforts to continue to address the challenge more difficult, committed project to improve system performance block chain.
However, block chain technology in high-speed ahead in the long term, but is facing a well-known "impossible triangle" technical bottlenecks.
2019 NSDI (computer network system in the field of international top will) Conference, two scientists from the Chinese Academy of Wangjia Ping and Wang Hao launched a professional paper on the block chain technology. Monoxide model ( "CO" model) they put forward to break the block chain bottlenecks can not triangle, triangle properties under the premise of meeting the security, performance and decentralized, as far as possible without introducing additional entity, does not introduce additional mechanisms, enabling existing algorithms to enhance the performance of more than a thousand times.
The model papers Wangjia Ping, Dr. Wang Hao of "carbon monoxide" and proposed block chain expansion program called asynchronous consensus group Monoxide can be in a test environment consists of 48,000 nodes worldwide, the Bitcoin network to achieve higher than 1000 times the processing amount of transactions per second, and a 1,000-fold state memory.
Appears Monoxide model is to break this bottleneck, under the premise of meeting the security triangle characteristics, performance and decentralized, as far as possible without introducing additional entities, an additional mechanism is not introduced.
Experiments show that, Monoxide existing model may be a single chain consensus algorithm, more than 1000 times horizontal expansion, so that the throughput of lifting more than 1000 times, but also the whole network computing (CPU) 2000 times to enhance the expression status of memory upgrade more than 2000 times.
理论上，横向扩展的倍数上限甚至能够达到10万量级。所以这一研究成果无疑会为区块链技术的发展带来质的飞跃。在区块链技术底层架构上，中国创造无疑再次在世界舞台上证明了自己的实力。
在公链研究上，深圳出发中国创造的Ruby路链也在区块链技术“不可能三角”上提出了自己的解决方案，Ruby路链首创双螺旋分子结构，提供智能合约、多链并行、跨链共识、链上大数据模块存储、无感链外应用块碎片化存储、快速应用转移等运行机制， 有效兼顾了公链去中心化、可拓展性、安全性的不可能三角。
基于区块链体系不断出现的问题，团队思考设计并迭代优化Ruby路链，提升传统公共区块链所有技术性能的同时推出了大数据模块、智能事物合约引擎、类N*RAID5链外应用扩展存储等技术概念。相关的技术成果和概念，将在区块链技术落地上发挥重要作用。
区块链技术落地商用中国遥遥领先
美国作为全球第一大经济体，尤其在世界尖端科技领域更是遥遥领先，但在区块链的发力中却没能占据绝对优势，其中能真正落地实施的区块链专利技术的表现明显不及中国，中国区块链技术的探索正走出一条不同于美国的独立路线，并且已经领先于美国。
从区块链技术应用最广泛、应用程度最高的金融行业来起。据知识产权产业媒体IPRdaily联合incoPat创新指数研究中心联合发布的“2017全球区块链企业专利排行榜100强”数据，排行榜中中国企业占49%，美国占33%，前十强中中国企业占了7家，美国只有2家。
除了各大传统国有银行之外，中国企业阿里巴巴、百度、腾讯、京东等互联网公司的加入，成为了金融领域中国应用区块链技术的一大亮点。比如，从全球申请区块链技术的相关专利来看，阿里巴巴排名全球第一，超过了IBM，专利数量高达90项。主要围绕新零售、物流、正品追溯等生活场景的应用展开。
Chinese Internet giant has taken the lead in the block chain technology business, the majority of traditional small and medium enterprises and Internet companies are also actively embrace this new thing. China Shenzhen starting to create Ruby Road chain is trying to reduce the development cost of traditional Internet and traditional industries with innovative block chain technology, may block chain business widely. Ruby Road chain for the traditional enterprise and Internet companies provide fuel block chain technology to accelerate the migration of the block chain application development becomes like fast Internet application development as flexible, low-cost, one-stop, full realization of the block chain business applications may be completely open a new commercial era.
Verify floor commercial block chain technology become truly effective touchstone, in a broad array of block chain project through which the real value of transport and technology upgrade, so the block chain technology for the benefit of more businesses and individuals. Internet development so far, any technological application that a real, everyday is a need to carry a lot of access and manipulate large numbers of users and records the status and information. This allows any application of a floor block chain technology, requires the technology itself has the ability to block chains bearing such traffic and user body mass. Clearly, the Chinese have such technological innovation and environmental conditions!
In the global competition for the right to block chain words, China is changing the world to create a grid! Go China!
