Combination of blockchain digital currency and entity
thank you
to know the difference between them, we need to know the definition of them first
digital currency: short for digiccy, which is the abbreviation of "digital
currency", is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
blockchain: blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database, also known as the trust machine
from the above definition, we can know that blockchain is a technology, and digital currency is a kind of virtual currency
digital currency is not equal to blockchain
many people will understand blockchain as blockchain. Here I want to correct that digital currency is not equal to blockchain. Digital currency is only an application of blockchain, and some digital currencies may not be applied to blockchain technology.

6. Tmall double 11
ant blockchain uses blockchain technology to trace the origin of tmall double 11.15 billion commodities
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.
blockchain 2.0 technology application represented by smart contract
the era of blockchain 3.0 has come. Behind the operation of all walks of life, we can see the mode of collaborative operation of blockchain. Therefore, blockchain is bound to widely and profoundly change the way of human life, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology.

blockchain is a distributed account book technology, and digital currency is currently the main application mode of blockchain technology
-
digital currency, based on the characteristics of blockchain, such as decentralization, traceability, non deletion and modification of records, confidentiality, convenient and rapid transaction, can be used as the carrier of asset digitization to a certain extent. Digital currency provides a feasible tool for asset digitization, safe, convenient and transparent transaction

digital currency is illegal in China. In 2017, many ministries and commissions of the state have issued relevant issues, please search online
Relevant national leaders pointed out that blockchain technology is an important breakthrough for independent innovation of core technology. Therefore, more and more attention will be paid to the application of blockchain technology, and the central bank is also studying DCEP, but it is not clear when digital currency will enter the legal application -
a few countries, such as the United States, Japan and Singapore, are tolerant of digital currency:
1) the United States: there are usdt, ETH, and Libra in the future
2) Japan: in April 2017, Japan implemented the revised capital settlement law, stipulating that digital currency and Japanese yen are legal tender and can be traded with each other
3) Singapore: Singapore is tolerant of digital currency, and it has become a common practice for Singaporeans to invest in digital currency< br />
Blockchain is the latest computer technology, the core is decentralized, distributed accounting. Digital currency is based on the underlying technology of blockchain. It can be said that without blockchain, there will be no digital currency. But without digital currency, there may still be blockchain. It's just that blockchain will be so hot, and it can't be separated from digital currency
in the future, digital currency will continue to develop. We can take advantage of the early stage to enter the digital currency and hoard some valuable digital currencies, such as Xunlei's playcoin
but at the same time, there is an unavoidable problem of digital currency, which is the lack of real economy support. At present, only a small part of the more than 1000 kinds of digital currencies circulating in the market rely on the economic support of miners. In other words, digital currency may be worth ten thousand yuan in the first second, but it may not be worth a minute in the second
therefore, before you make digital currency, you must investigate, analyze and choose carefully, so as not to cause losses to yourself
blockchain technology has been questioned by the collapse of the centralized currency exchange, but its potential to solve the trust and centralization problems of the existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of bitcoin and digital currency. It uses a single shared ledger to store information. It is no longer to let a single central organization obtain the account book, but to obtain multiple copies of the same distributed account book by different nodes in the peer-to-peer network. Shenzhen yuanzhongrui blockchain technology adopts advanced encryption technology to ensure that any new information in the account book can not be tampered, unless it meets some preset parameters. Moreover, this kind of Ledger has stronger defense against external attacks, such as network attacks, because this decentralized system does not have a single point of failure with high cost of centralized information architecture. At the same time, all trusted nodes can affect any modification of the ledger, provided that they meet the specific preset parameters. These changes will be immediately reflected in the ledger, and all trusted nodes can obtain relevant data to make correct decisions. It can also adjust the design of the distributed ledger, create a hierarchical system within the architecture, and configure appropriate access rights and different levels of authority
blockchain and distributed ledger technology are concive to change the management mode of land registration. At present, the credibility of the real estate market is at the lowest level, which is attributed to the inefficient and opaque property registration system. The system relies on the centralized acquisition of land registration and corresponding property transaction information. Using distributed ledger technology to obtain, manage and modify these information can ensure that the public will not be infringed by land transaction fraud. Similarly, distributed ledger can simplify and integrate cross instry and cross regulatory compliance process, because it contains real-time compliance information needed by government departments, banks, investors and other third parties. By integrating data points of multiple projects and providing feedback on beneficiaries' project participation, we can better track the implementation of social welfare plans
at present, the biggest problems of technology development include: transformation cost of unique data storage system, data reliability verification of network nodes or all levels, privacy and security dimension of decentralized data acquisition, and revision of information technology act. What's important is that blockchain technology will change the way the government interacts with citizens, and this huge change is bound to be resisted by civil servants. These are all possible problems. We should take immediate action to formulate a regulatory framework to guide application development in addition to adopting blockchain technology.
