Is blockchain good or bad for society

2. A brief review of the origin of blockchain
blockchain is the underlying system of distributed ledger in bitcoin. Bitcoin ledgers are built in a distributed and spontaneous way. Anyone can generate new currency blocks by performing specific cryptographic calculations, so as to obtain a digital "currency" that can be used for transactions. Bitcoin's impact on the world monetary system can be said to be subversive, which is also an important reason why it has attracted a lot of people's strong attention since it came out. After that, there were dozens of similar electronic currencies such as
"lightcoin". The abstract extraction of distributed digital currency technology from bitcoin forms a "blockchain" technology, which can be used in more fields
the basic idea of blockchain is to establish a network-based public ledger (data block), each block contains the information of a network transaction. All the participating users in the network work together to keep accounts and check accounts. All the data are open and transparent, and can be used to verify the effectiveness of the information. In this way, the authenticity and non tamperability of information can be guaranteed at the technical level without the central server as the trust intermediary
the significance of blockchain lies in "decentralization", which can fundamentally solve the fraud and rent-seeking phenomenon in value exchange and transfer by building a more reliable network system. With the popularization of blockchain technology, the digital economy will be more authentic, and the economic society will become more fair and transparent
not only digital currency, but also blockchain technology is infiltrating into more innovative fields.
virtual digital currency such as bitcoin is just an application scenario of blockchain technology. Theoretically speaking, based on the characteristics of blockchain technology, human beings can create a very rich form of services and procts, such as finance, government, enterprises, etc There are a large number of scenarios suitable for blockchain technology in cross instry and other fields, with broad prospects. At present, many countries around the world have started the research of blockchain technology, and a series of instry organizations and alliances have been established. However, as blockchain technology is a brand-new technology, which subverts the traditional centralized mode, major institutions are still in the research stage, with only a small number of actual projects landing, and the great development of the instry has just begun
now, blockchain economy is on the eve of outbreak. The exploration of financial instry is ahead of others, while the application of other instries is developing rapidly. The obvious advantage of blockchain instry application is to optimize business process, rece operation cost and improve collaborative efficiency. This advantage has been graally reflected in financial services, Internet of things, public services, social welfare and supply chain management
as the backbone of emerging technologies, blockchain is not only used in the field of virtual currency, but also in other fields such as finance, medical care, intellectual property certification, etc. a large number of excellent enterprises have emerged in China to explore or enter the blockchain instry. According to the in-depth analysis report on business model innovation and investment opportunities of blockchain instry released by foresight Instry Research Institute, as of the end of 2016, there were 105 blockchain related enterprises in China, 80% of which were concentrated in eastern coastal cities, including Shanghai, Hangzhou and Taipei
from the perspective of global blockchain technology application development, as of April 2017, financial service companies accounted for 55.43% of the 267 blockchain venture capital companies; From the perspective of the Chinese market, 34 of the top 50 blockchain venture capital companies in 2016 are involved in financial services, mainly in cross-border payment, bill discounting and financial service platform<
analysis of the development trend of blockchain
the combination of blockchain and cloud computing is more and more close, and baas is expected to become a public trust infrastructure
cloud computing is the general trend. We believe that the combination of blockchain and cloud is also an inevitable trend. There are two modes for the combination of blockchain and cloud, one is blockchain in the cloud, the other is blockchain in the cloud. The latter, namely baas, blockchain-as-a-service, refers to that the cloud service providers directly provide blockchain as a service to users. In the future, more and more cloud service enterprises will integrate blockchain technology into the ecological environment of cloud computing. By providing baas function, they can effectively rece the deployment cost of enterprise application blockchain and rece the initial threshold of innovation and entrepreneurship
the security problem of blockchain has become increasingly prominent, and security protection needs the overall consideration of technology and management
blockchain system is almost perfect mathematically, with the advantages of openness and transparency, difficult to tamper, reliable encryption, anti DDoS attack, etc. However, from the engineering point of view, its security is still restricted by infrastructure, system design, operation management, privacy protection and technology update iteration. In the future, we need to consider the overall situation of technology and management, strengthen basic research and overall protection, so as to ensure the application security
the competition of blockchain is becoming increasingly fierce, and patent competition has become an important field of competition
with the increase of participants, the competition of blockchain will become more and more fierce, and the competition is all-round, including technology, mode, patent and other dimensions. We believe that in the future, enterprises will strengthen the layout of blockchain patents. Since 2014, the number of blockchain patent applications has grown explosively. Blockchain patents are mainly distributed in the United States in North America, the United Kingdom in Europe, China and South Korea in Asia, and this pattern will be maintained in the future. The patent gap between China and the United States is narrowing, and the number of applications in China in 2016 has surpassed that in the United States. It can be predicted that the patent competition of blockchain will become increasingly fierce in the future
with the acceleration of domestic policy process, the development of the instry ushers in a new opportunity
blockchain has attracted attention from all walks of life e to its core advantages of high performance, high security, high-speed access, efficient operation and so on. In the context of the rapid development of blockchain, China conforms to the needs of globalization, closely follows the international pace, and actively promotes the research, standardization and instrialization development of domestic blockchain related fields
trustworthiness is the core requirement of blockchain, and the importance of standards and specifications is becoming increasingly prominent
in the future value delivery network based on blockchain, we will completely use algorithms and software to build the trust foundation. However, we believe that this is far from enough, and we need the standard to increase the credibility of the blockchain. In the future, the standard of blockchain will standardize the technology and governance of blockchain from the perspective of users, business oriented, and from the dimensions of smart contract, consensus mechanism, private key security, and authority management, so as to enhance the credibility of blockchain and add weight to the trust of blockchain.

3. 1、 Blockchain will play the role of "recing costs for the real economy". At present, the high cost and low profit of the real economy lead to the lack of capital support for the real economy. In the operating cost, the proportion of management cost and financial cost is not low. Blockchain technology can effectively help enterprises rece the cost of these two parts
secondly, blockchain will play a role of "improving the efficiency of instrial chain collaboration". Enhancing instrial collaboration is an important way to promote manufacturing in China to move towards the middle and high end. However, in many instries, the efficiency of instrial chain collaboration is still not high, especially in the field of international trade
thirdly, blockchain will play a role of "building an honest instrial environment". At present, the construction of China's social credit system is accelerating, but in some cases, the process of building trust among partners is still slow, it is difficult to obtain all kinds of credit information, and it is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. Through the "transaction on the chain", all aspects can more easily find out the accurate historical credit situation of the counterparties, and establish the cooperation mechanism faster; Banks can also give credit to enterprises more safely based on transaction records, and promote the solution of the problems of "difficult, expensive and slow financing" of small, medium and micro enterprises operating in good faith
in addition, blockchain can make use of smart contracts to avoid default and fraud to a large extent, and can also make efficient and convenient payment scenario applications in combination with blockchain asset wallet. As early as in the blockchain circle, there have been many innovation forums and Instry Summit aiming at the direction of blockchain enabling the real economy, and combining with the local economic instry to carry out landing optimization. For example, the world blockchain conference Macao station intends to make a deep integration with the local economic instry, and use and popularize the blockchain assets with the payment means of magic chain wallet.

4. Chongqing jinwowo analysis:
the application of data signature and encryption technology of blockchain has realized tamper proof, unified standard and efficient exchange of commodity information
based on this, we can achieve trust sharing among brands, channels, retailers, consumers, regulatory authorities and third-party testing institutions, and comprehensively improve the brand, efficiency, experience, supervision and overall revenue of the supply chain.

5. What is blockchain technology

before discussing how to apply blockchain in daily life, let's talk about what blockchain is and how it works

blockchain is an open distributed database, which is essentially a computer file used to store information (data)

the name of blockchain comes from its structural characteristics: the file is composed of data blocks, and each block is linked to the previous block to form a chain. Each block contains data, such as transaction records and records when the block was edited or created. Information (data) is stamped with time stamp, which is the origin of blockchain

it is crucial that, unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and data is completely copied (distributed) on multiple computers

because it is a decentralized way to store and access data, it becomes extremely secure. Different from the centralized database, the attacker does not have a single entry point, so the data security is more guaranteed<

in addition to the two characteristics of decentralization and security, blockchain has become a leading technology which is different from other technologies:

tamperability: once entering the blockchain, any information can not be changed, even the administrator can not modify this information. It makes blockchain easy to audit

accessible: all nodes in the network can easily access information

no third party: blockchain can help point-to-point transactions, so whether you are trading or exchanging funds, you do not need the approval of a third party. Blockchain itself is a platform

the impact of blockchain technology

first, the open and tamperable nature of blockchain technology makes it possible to decentralize the trust mechanism. It has the potential to change the financial infrastructure. Various financial assets, such as equity, bonds, bills, warehouse receipts and fund shares, can be integrated into the blockchain ledger to become digital assets on the blockchain, which can be stored, transferred and used in the blockchain Deal. It has a broad application prospect in the financial field. For example, it has typical applications in cross-border payment, insurance claims, securities trading, bills, etc

Second, the current Internet of things ecosystem relies on the centralized network management architecture, and all devices are connected through the cloud server. With the expansion of the network scale, the infrastructure and maintenance of centralized cloud servers, large servers and network equipment will occupy a high cost

in the decentralized Internet of things, blockchain is a framework to promote transaction processing and cooperation among interactive devices, and each device on the network can operate as an independent and micro business entity< Third, public service is a factor to promote economic growth and social progress. The supply of public service has an important impact on various subjects, systems, cultures, attitudes and behaviors in the process of political, economic and social development. The traditional notarization relies on the government, and the limited data dimension and the historical data information chain that has not been established often lead to the government and schools unable to obtain complete and effective information. Using blockchain, tamper proof can be established. In the fields of digital rights, intellectual property rights, certificates and public welfare, new authentication mechanisms can be established to improve the management level of public services.

6. At present, what blockchain can bring to the society is regionalization.

7. Blockchain practitioners have come to answer this question. We are familiar with financial, medical and ecation instries. However, in terms of social management, there are already leading blockchain technology companies in China that can bring new changes,
such as wangchain technology, which can achieve new effects in proxy voting, identity authentication, file management, justice, inheritance, personal social credit, and business administration.

8. Blockchain has changed our lives. Now the future cloud node of four pieces of technology is a better mining machine recognized by everyone.
