Tree graph blockchain is the progress of blockchain
driven by policy and market, China's blockchain related instries are expected to move from virtual to real
in the context of rapid development of blockchain, China should comply with the needs of globalization, keep up with the international pace, and actively promote the research, standardization and instrialization development of domestic blockchain related fields. Compared with the increasingly stringent supervision of bitcoin and other digital currencies, the support and encouragement of blockchain technology has reached a consensus in the world, and the domestic blockchain technology will also receive national and local policy support in the next few years. Driven by policy and market, blockchain related instries are expected to move from virtual to real, and blockchain technology will accelerate the exploration of possible application scenarios< According to the data of the "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, the global blockchain market scale is expected to increase from US $411.5 million in 2017 to US $7683.7 million in 2022, with a compound annual growth rate of 79.6%. In view of the wide application range of distributed ledger, the rising market value of cryptocurrency, the strong demand for improving transparency, security, efficiency and simplifying process, and the popularity of blockchain as a service (
baas), the blockchain market will expand rapidly. In addition, communication services, international trade, supply chain management, programming platform, payment, smart contract, digital authentication and so on are also in urgent need of blockchain technology, which will create a lot of growth opportunities
as an integrated application of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other technologies, blockchain has become a research hotspot of the United Nations, the International Monetary Fund and other international organizations as well as many national governments in recent years, and the instry has also increased investment. At present, the application of blockchain has extended to the Internet of things, intelligent manufacturing, supply chain management, digital asset trading and other fields, which will bring new opportunities for the development of cloud computing, big data, mobile Internet and other new generation information technology, and have the ability to trigger a new round of technological innovation and instrial change
by 2022, the payment sector may occupy the largest share of the blockchain market
relying on blockchain technology, real-time payment of assets can be realized, which not only has the characteristics of tamper proof and digital authentication, but also can greatly save the cost of settlement for financial institutions and banks. In addition, blockchain makes payment automation possible, eliminates the need for middlemen, and saves labor costs and time for buyers and sellers. Thanks to the above advantages, it is expected that the payment sector will be the heaviest one in the whole blockchain market
the fastest growing region will be the Asia Pacific region.
blockchain service providers in the Asia Pacific region are good at designing and developing cryptocurrency platforms with friendly interface, cost saving and high speed, and extending the application of blockchain in many instries. Both large enterprises and small and medium-sized enterprises are actively seeking risk financing, investing in and developing the most cutting-edge blockchain technology. In addition, the real estate instry of some countries in the Asia Pacific region is expected to rapidly transform from translucency to full transparency, which also helps to enhance the development prospects of blockchain in the Asia Pacific region.
Blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code
extended data:
the evolution mode of blockchain is as follows:
& 9642; Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0 - Implementation of distributed applications in various instries
blockchain features:
1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, 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
2. 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. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. 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
The information can not 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. Therefore, the data stability and reliability of the blockchain are extremely high5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit
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. In short, in the blockchain system, the transaction data generated by each participant will be packaged into a data block after a period of time. The data blocks are arranged in chronological order to form a chain of data blocks. Each participant has the same data chain and cannot be tampered unilaterally, Any modification of information can only be carried out with the agreement of the agreed proportion of subjects, and only new information can be added, and the old information cannot be deleted or modified, so as to realize the information sharing and consistent decision-making among multiple subjects, and ensure that the identity of each subject and the transaction information between subjects can not be tampered with, open and transparent
the technical commonness of blockchain projects: block, account, smart contract and consensus, which constitute the general model of the current blockchain system
