What does it mean to open blockchain application

1. One of the three conditions for large-scale implementation of blockchain applications is blockchain 3.0 technology, which can improve the performance, ease of use, operability and scalability of blockchain, and involves new technologies such as side chain, sub chain, cross chain, layering, fragmentation and zoning. According to Xiao Feng's observation, most of these technologies will mature in 2019, and the main network will go online. The launch of these new technologies is the premise of large-scale commercial application of blockchain. So from a technical point of view, after 2019, the large-scale commercial application of blockchain can be expected
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.

3. You're talking about gold miners

there are 56 gold fishing games in 973.

4. Blockchain and digital currency are two independent indivials, and the term blockchain currency does not exist. At present, the mainstream digital currencies include bitcoin, Ethereum, bitcoin, cash, grapefruit, etc. the corresponding subtitle abbreviations are BTC / eth /

5. Triporg travel: a blockchain + tourism service platform, which can provide people with travel services such as train tickets.

6. To tell you the truth, everyone in the blockchain is afraid of currency speculation. Before that, there were several persons in charge of the blockchain platform in Beijing who were arrested because of the illegal trading of currency. So it's better to follow the official government. Recently, the high tech Zone set up a blockchain platform project in the central area, which was officially initiated by the information instry park, It seems that we are now soliciting enterprises to go up the chain.

7. The application of pre blockchain technology is in an exploratory period, with more conceptual things and less real transactions and projects actually implemented. However, now some instries have begun to try blockchain technology. According to the analysis of jinwowo network technology, within three years, blockchain technology can be deeply integrated with the instry, and blockchain may be implemented in the three fields of sharing economy, supply chain management and digital asset management.

A: the practical application of blockchain technology

I. in financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

the application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

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 field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

1. Medical

in the medical field, data sharing between hospitals and micro v-bq-y means more accurate diagnosis, more effective treatment, and can promote the overall service ability of the medical system. However, data sharing also means the problem of doctor-patient privacy exposure. Blockchain technology allows hospitals, patients and all parties in the medical interest chain to share data in the blockchain network without worrying about the security and integrity of the data

2. Logistics

at present, the most critical problems of logistics are missing and damaged express. Blockchain technology can record all links in the process from delivery to acceptance of goods, and directly locate the problems in the intermediate links of express delivery through network consensus, so as to ensure the traceability of information, so as to avoid the occurrence of problems such as warehouse explosion, package loss, wrong picking and wrong picking

3, big data

big data is an indispensable link in the development of modern enterprises, and the security and non tamperability of blockchain can liberate more data security. Based on the consensus of the whole network, the data reliable blockchain data, which is the basis of micro v-bq, is tamperable and safe, and makes the quality of data obtain unprecedented strong trust endorsement, and also makes the development of database enter a new era

4. Distributed business platform

combined with the advantages of decentralized blockchain technology and distributed account book, there are many integration points worthy of attention in the field of this technology and business platform. If we can take blockchain technology as the core support technology, research and develop the transaction mode and transaction system based on blockchain technology in the field of commodity trading, and trade directly, in this way, Procers can get more benefits and consumers can get lower proct costs

Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer

among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamp

The

network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes

the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives

the contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain

The

application layer encapsulates various application scenarios and cases of blockchain

in this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology

10. Blockchain is a disruptive technology that will change many instries in the future, just like the Internet many years ago. Blockchain search on the Internet, Tencent's blockchain invoice and Alibaba's rookie logistics are all using blockchain. At present, there are companies specialized in providing this kind of blockchain landing service for enterprises, and the small area is one of the representatives
