Blockchain 30 standard
If bitcoin represents blockchain version 1.0, it proves to the world that digital currency can be realized. Then Ethereum represents blockchain version 2.0, which lets you know more about the play of blockchain, decentralized applications and smart contracts. In 2018, blockchain will enter the stage of 3.0, application and scenario landing will be the core of blockchain, and blockchain based applications in various instries will spring up, which will be the early dividend period of the last stage of blockchain development. The demand for talents driven by the application of blockchain technology has become increasingly large. Blockchain technical talents have become the new professional talents, which are highly competitive, and also have enviable high salaries
whether to form a meaningful large-scale consensus: one of the outstanding advantages of blockchain is that it can effectively form a large-scale consensus by opening account books and notifying the whole network. At present, there is no need to form a network wide consensus for many projects. Some projects are just for crowdfunding and token issuance. The blockchain consensus of projects is meaningless. Does this model have network effect: network effect means that a project will become more and more valuable with more and more users of the project, because the value of the project is not in the users themselves, but in the connection network between users. Bitcoin is a typical example. The more user nodes there are, the more links between nodes will grow exponentially, and the whole ecosystem of bitcoin will be more valuable
of course, in addition to these points, there are many basic principles to judge the project, such as effective incentive mechanism, strong team, project solving pain points, and so on
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
China has started to establish a national standard for blockchain to promote the construction of blockchain standard system from top-level design, which is expected to be completed by the end of 2019 at the earliest
in this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although the blockchain has disruptive technology potential, we must realize that the blockchain is still in its infancy, far from reaching the stage of subverting the world
Yu Kequn stressed that the independent and controllable blockchain network is intended not to be controlled by others technically, but also to promote the healthy development of blockchain. Security is the future life of blockchain. Only its own security can make blockchain technology landing. This requires us to pay equal attention to the development of blockchain technology and its security attributes, even ahead of timein this regard, Li Ming also said that an important part of the standard is the information security standard, which can also see the importance of security to blockchain technology. He also pointed out that the development of blockchain standards does not mean that it will rapidly promote the development of the instry, but give the instry certain guidance. Previously, China has suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has formed more than 200 patents in terms of international blockchain, and even stands in the forefront of world technology. Therefore, we also need to firmly grasp our right to speak

secondly, test verification includes test cases, test plans, test tools and test environment. According to GB / T 25000.10 -, 4.3.1 proct quality model and blockchain reference architecture
Third, promote the standard application demonstration. It can be divided into three stages. Firstly, it needs to go through the research stage, including the preparation of the white paper, the formation of the draft and the establishment of the standards working group at the end of 2016. In order to promote the development of blockchain technology, the focus of the next stage is to find real application cases in various instries (financial services, supply chain management, entertainment, etc.) and create typical cases. Li Ming said that this will be carried out graally in the second half of this year Fourth, build open source community, including open source official website, instry alliance, training and certification, summit and hacker marathon, technical committee, communication tools, etc. The goal is to form an independent, safe and controllable general technology solution for blockchain, to track and study the development trend of foreign blockchain open source, to explore the possibility of domestic technology open source, and to form an open source solution suitable for Chinaecol ecol is an intelligent, efficient and molar blockchain ecosystem and application scenario solution with unified standards for the security vulnerabilities of blockchain technology, which is committed to building a programmable society with smart contracts. Ecol ecosystem enables the blockchain ecosystem to use blockchain, big data, Internet of things, artificial intelligence (AI), virtual reality (VR) and many other technologies to help people from all walks of life seamlessly connect the existing systems and services with the blockchain, and jointly accelerate the implementation of the blockchain from "technical concept" to commercial scene

Ten core technological innovations to jointly build a complete ecol ecosystem.
the resolution calls on the idea of bitcoin, but does not directly mention its name. Instead, it calls it "alternative illegal currency". Blockchain technology is the key point, which points out that this technology has the potential to "fundamentally change" the way trust and security are built on online transactions
but in fact, the United States has not taken action to formulate this rule. However, there is a global blockchain alliance R3 in the process of formulating the standard for the use of blockchain. Of course, blockchain is just a technology that can be used by any enterprise. In China, there is a project called decent, which is more avant-garde. It uses blockchain technology to build a decentralized content publishing platform, but it may encounter some problems in China.
