What does blockchain flow restriction mean
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
Blockchain is a shared database. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on
main features:
1. 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
2. Openness. The foundation of blockchain technology is open source. In addition to the private information of all parties to 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
3. Independence. Based on consensus specifications and protocols, 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. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

application direction:
1. Payment: for example, in terms of time, traditional cross-border remittance takes 10 minutes or several days, while blockchain cross-border remittance can achieve remittance in seconds e to decentralization. In terms of convenience, traditional cross-border remittance needs to wait until the next day after 19:00, while blockchain cross-border remittance only needs one mobile phone to realize all-weather remittance
2. Sharing medical records: the medical data blockchain sharing platform can achieve many application scenarios. Patient history data and other information can be linked, and medical history and image data can be viewed by personnel entering the system. These medical data can also be used for modeling and machine learning

Blockchain finance is actually the application of blockchain technology in the financial field
blockchain is an underlying technology based on bitcoin, and its essence is actually a decentralized trust mechanism. Through sharing in distributed nodes to maintain a sustainable database, the security and accuracy of information can be achieved. The application of this technology can solve the trust and security problems in the transaction, and the blockchain technology has become an optional direction for the future upgrading of the financial instry. Through the blockchain, both parties of the transaction can carry out economic activities without the help of the third-party credit intermediary, so as to rece the cost of the global transfer of assets
extended data:
since 2016, the major financial giants have also heard the news and launched blockchain innovation projects one after another to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency. Standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization. After careful digital algorithm, it is written into the blockchain to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency
in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the global asset circulation, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016, at which the discussion on the realization of digital circulation of assets, block chain financial transaction mode, and block chain financial transaction mode will be held It also discusses the application of blockchain service and social public instry
Blockchain itself is not illegal, but if it is used illegally, it is illegal
Li Bin, deputy director of Chongqing big data application and development administration, said that as a disruptive innovative frontier technology in the field of big data intelligence, the Chongqing municipal government attaches great importance to active layout, and the municipal government and Yuzhong District Government jointly build a blockchain base. In the second half of last year, the government issued the opinions on accelerating the cultivation and innovative application of blockchain instry, It has officially launched the construction of a place for strategic innovation of blockchain
while actively encouraging the technological progress and instrial development of blockchain, we will resolutely prohibit the illegal use of blockchain technology in accordance with the requirements of relevant national policies
at present, China's blockchain technology and application continue to innovate, and are graally applied in supply chain finance, credit reference, proct traceability and other fields, with huge development space. As a new technology, if blockchain wants to realize large-scale practical application, it must strengthen the cooperation of instry, University, research and application, and promote the continuous development and maturity of technology and application
since 2017, the development of blockchain technology has aroused the deep concern of the government, enterprises and other sectors. Because of its decentralized, tamperable and traceable characteristics, blockchain attracts investors to add weight to this new technology field. For the previous hot speculation of blockchain technology, the cognition of it and investment circles has become increasingly rational

Why is the Internet era coming to an end and the blockchain era coming
Once the
blockchain develops, it will burst out more innovation. As the first proct of blockchain, bitcoin has proced many innovations since its birth. For example, small cross-border payment, recording transfer transactions between currencies, recording various stocks, registering housing property rights, recording program codes, etc.
the steam age liberates social proctivity, the electrical age enlivens social cooperation ability, the Internet age connects the world, and the blockchain era will let us truly realize freedom
