Blockchain technology should be included in
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
as we all know, blockchain technology is an independent underlying architecture from bitcoin system. From the perspective of architecture model, it is a set of distributed ledger, which is naturally used for bookkeeping
in the blockchain technology, if you want to generate accounting records, you need to have the transaction and flow of funds. Therefore, in the initial blockchain technology, the cryptocurrency corresponding to the main network is used as circulation goods, and the circulation transaction records of cryptocurrency between the accounts of the main network of the blockchain will be recorded on the main network
different from other transaction record databases, transaction records on the main network of blockchain technology will be recorded on all block nodes (i.e. all data blocks) in the main network, which is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to store all records, Every block on the chain has the transaction data of the whole chain, that is to say, every data block is the center
another feature of blockchain technology is that it can't be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can change the record. Even if you change it, all other data blocks will also record real data, and each group of data can be traced back to the first time
because of these characteristics of blockchain technology, after the advent of bitcoin, blockchain has also attracted a lot of attention, and many people also began to want to use blockchain technology to make a centerless, traceable and unchangeable data, so as to ensure the credibility of the data
however, blockchain technology also faces many problems, such as single application scenario, non modifiable original error data, non recoverable currency stolen by hackers, etc.
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.
A: application fields of blockchain technology
I. financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields
Second, the Internet of things and logisticsblockchain can also be naturally combined in the field of Internet of things and logistics
through the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management
Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs Sixth, the data stored on the public welfare fieldblockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios
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

2019 - blockchain "mainstream application year"
since August 2018, the electronic invoice of blockchain was issued for the first time in Shenzhen. So far, it has issued more than 6 million electronic invoices, with an amount of 4 billion yuan, and has access to more than 5300 enterprises, Covering more than 110 detailed instries. In addition to the field of electronic invoice, blockchain has also been successfully implemented in many project scenarios, such as supply chain finance, legal deposit, cross-border payment, etc.
at the recent "thousands of people watching fire" conference of blockchain instry, the reporter of economic daily learned that in 2019, the technology implementation and application has brought blockchain into the "mainstream application year". On the one hand, many Internet giants have a solid technical foundation, on the other hand, they actively explore more valuable scenarios to find development opportunities in the enabling real economy
"blockchain technology can play the role of anchoring, sharing and increasing trust in the whole social information flow, making the chaotic information credible. Compared with the past, this is a" qualitative leap. " Zhang Kaixiang, chief architect of Weizhong bank's blockchain, said, "risk control and business rules design based on trusted data can improve efficiency, rece risks and rece operating costs." He pointed out that as a connector, it is not meaningful for a single enterprise to operate the blockchain, and it is more meaningful to share it as an open source solution to realize the ecological co construction of the instry
"we have been exploring and practicing open source, starting from the underlying technology platform and combining with the scenes of finance, instry, Internet of things, culture and entertainment, to jointly build an open, transparent and efficient technology and instrial community. Open source ecology helps to activate the creativity of the instry. We will continue to start from the open source community and improve a complete set of systems such as system construction and skills training, so as to benefit more people. "
in 2019, the market scale of China's blockchain instry will exceed 100 million yuan
China's blockchain instry is still in its infancy, but with the continuous support of national policies, the continuous progress of instry technology and the increasing demand of downstream application fields, China's blockchain instry is expected to continue to maintain high-speed growth. According to the statistical data of in depth analysis report on business model innovation and investment opportunities of China's blockchain instry published by foresight Instry Research Institute, the market scale of China's blockchain instry was less than 6 million yuan in 2011, and the market scale of China's blockchain instry increased by 32 million yuan by 2017, By 2018, the market scale of China's blockchain instry has reached 67 million yuan, always maintaining a rapid growth rate of more than 80%. It is predicted that the market scale of China's blockchain instry will exceed 100 million yuan in 2019, and that in 2022, driven by policy support and downstream demand, the market scale of China's blockchain instry is expected to exceed 450 million yuan
market size statistics and growth forecast of China's blockchain instry from 2015 to 2022
data source: the audited enterprise asset confirmation, registration and circulation records, etc., sorted out by foresight Instry Research Institute, are stored on the platform in the form of traceability. Based on this, banks can carry out fast financing and loan business, save the cost of guarantee and other links, greatly improve the efficiency, and make the risk of financing and loan controllable as a whole
electronic data storage is an important application field of blockchain technology.
the provisions of the Supreme People's Court on Several Issues concerning the trial of cases by Internet courts, which came into effect in September 2018, clearly states that electronic data storage can be solved by blockchain and other technical means. Xiang Dan, vice president of bibox digital asset trading platform, said that electronic data deposit is an important application field of blockchain technology“ Blockchain technology has the characteristics of preventing tampering, leaving traces in the event, post audit and security protection, which is concive to improving the credibility and authenticity of electronic evidence. The combination of blockchain and electronic data storage can rece the cost of electronic data storage, improve judicial efficiency and enable judicial business. For example, the contract management based on blockchain has been applied in many Internet courts. "
according to Zhou Jianrui, co founder of coinword, a trusted content community, the application of electronic data storage based on blockchain can also help deepen the reform of "release management and service" and improve administrative efficiency. In Beijing Haidian District and other pilot areas, blockchain technology is playing the role of efficient data sharing, secure transmission and credit support. When applied in the field of government affairs, it can realize real-time data sharing of various departments and effectively assist window personnel and examination and approval personnel to quickly verify the authenticity of materials. For example, the public security, civil affairs, housing management and other departments "on the chain", in dealing with real estate transactions can be fast and accurate, "one key" verification of multi-party information, greatly saving social costs
there will be two opportunities for the application of blockchain
because the social recognition of blockchain is not high, the people who understand and use blockchain are still very limited, and the penetration of blockchain into the real economy still needs a graal process. " Yuan Yuming, CEO of fire coin China, introced that they used the open, transparent and tamper proof characteristics of blockchain to explore a new path of art traceability and anti-counterfeiting by means of high-precision full pixel scanning and archiving; By constructing the trust mechanism in the multi-party cooperation scenario, the integral information platform for multi-party participation and resource sharing is developed“ Next, there will be two opportunities for blockchain application:
one is training. With the entry of enterprise giants one after another and the continuous penetration of the real instry, more people will learn about blockchain through training, which will become a new market demand
the second is to provide consulting and technical solutions to more traditional enterprises to help them penetrate the blockchain into more traditional fields and promote the consumption rection, efficiency enhancement, transformation and upgrading of the real instry. "
at present, China's blockchain instry mainly focuses on computing infrastructure, radiates digital currency, and derives to the penetration process of blockchain application. Infrastructure includes chip miner, mine pool and cloud computing power. Digital currency, wallet and exchange constitute the monetary system. Asset authentication, financial services and charity form a rich application ecology. From the development trend, the mining machine has experienced CPU, GPU, FPGA, until now through ASIC chips to customize mining, we can see from the mining machine calculation force curve that the mining machine calculation force has been in a soaring trend.
the inclusion of the "blockchain" key projects in the "14th five year plan" national key R & D plan is not only the implementation of the policy documents of national ministries and commissions, but also the need to speed up the blockchain technology and instrial layout, which is of great significance for the subsequent development of blockchain in China. At the same time, national ministries and commissions and provinces and cities have also formulated and issued relevant policies to support the development of "blockchain", attracting blockchain professionals in an all-round way, promoting blockchain technology research, speeding up the layout of blockchain instry, and bringing blockchain technology and instrial development into the fast lane
since 2014, easysaver has been deeply engaged in the research and development of underlying technology and application innovation of blockchain. Based on the electronic data preservation of blockchain, easysaver has launched a number of brands such as Junzi signature in the field of blockchain electronic signing, micro right in the field of blockchain intellectual property protection, and zhongzhengbao in the field of blockchain Internet justice. In the future, easy security will continue to deepen the research and development of the bottom layer of the blockchain, promote the breakthrough of the core technology of the blockchain, optimize the application of the blockchain in various instries, help more enterprises quickly complete the transformation and upgrading through "blockchain +", and release new momentum for the development of the digital economy.
