1. 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.

2. Many relationships between people are based on trust, such as friend relationship, cooperation relationship, transaction relationship, etc
take trading activities as an example. In the past, the two sides who did not trust each other usually chose an intermediary to guarantee a transaction. In the mobile Internet era, we chose Taobao shopping because Alipay provided us with an intermediate guarantee. We chose to drop dripping because it provided us with information matching.
however, these intermediaries are centralized and have their own interests. Sometimes they are not so reliable and trustworthy. Theoretically, Alipay's centralization of accounting has been artificially falsified. Part of the reason for Didi's troubles is that they only think from their own standpoint
what blockchain does is the machine of trust, which replaces the role of trust intermediary with code, ensures the fairness and justice of the whole system through consensus mechanism and distributed accounting, and provides a trust without trust
for example, in the future, people can abandon the intermediate platform and realize point-to-point docking and free trading through blockchain. Shopping does not need to go through an intermediary, and taking a taxi does not need to go through Didi. In this way, we can really achieve "no middleman to earn the price difference" and rece the cost.

3. Blockchain has the following characteristics:
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Decentralized
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
openness
the system is open, in addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all, and anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
autonomy
blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
information cannot be tampered with
once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high<
anonymity
since the exchange between nodes follows a fixed algorithm, their data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective by themselves), so the counterparties do not need to trust themselves by disclosing their identities, which is very helpful for credit accumulation
