Is digital currency a revolution

1.

digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)

digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes

based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

extended information:

the process of digital currency trading through the platform is as follows:

(1) investors should register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time

(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures

(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed

2. Digital money has quietly entered many people's lives, ranging from the digital savings fund in the bank to the shopping fund in a certain business. And the possibility of legal or official issuance of digital currency has not started from today. With the rise of blockchain technology, legal digital currency has become a key research field of central banks in recent years. Central banks in Britain, Canada and other countries have indicated that they will set foot in this field and put forward their own plans. As early as January this year, the central bank held a seminar on digital currency and said that it had set up a special research team to strive for the early launch of the digital currency issued by the central bank. In fact, since 2014, the central bank has set up a special research team to conct in-depth research on the framework of digital currency issuance and business operation, key technologies of digital currency, issuance and circulation environment, and legal issues.

3. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items[ 1-2]
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and take action as soon as possible to completely ban the electronic currency.

4. On the basis of limited value, there will be great bubbles at the same time. Just like beer, many bubbles will emerge after opening, so that the real value can be seen until the market calms down.

5. Blockchain is a distributed ledger database, and its core is the essence of trust, that is, the ledger is still used, and there are records that can not be tampered with in the ledger, Its design is as like as two peas in the traditional account:
add a signature
in each record. Each device in the block chain network maintains a complete and identical account
another feature of the block chain is that this ledger book is kept in every computer, and each one is exactly the same as the 2. This can ensure that one account book is damaged (the disk is damaged or tampered with to make it unusable), and the account books on other machines can still be used to ensure that the data will not be lost
the above two points are the core technologies for blockchain to establish trust relationship, which ensures that the data is reliable and can not be tampered with. This revolutionary realization of trust transfer between two strangers does not require the participation of intermediate institutions. With this foundation, the whole "new institutional economics" will no longer exist, and even the trust companies derived from it will be replaced, This is probably why Alipay announced the introction of block chain technology in January 2017. It is bold to predict that Internet Co will be built on the block chain in the future. What we can imagine is the property chain, food safety chain, financial service chain, chain chain and so on.
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.

6. Go language has not shown a clear direction since its appearance. Google employees call it an "experimental language", saying that it tries to integrate the development speed of dynamic languages such as python with the performance and security of compiled languages such as C or C + +. A supporter of go language summarizes that go language is as follows: simple, fast, safe, concurrent, happy programming, open source; But go language lacks direction and the attempt of its "synthesizer" will easily lead to its failure to learn from cats and dogs, and become a four unlike. Nevertheless, the editors still think that go language has great potential: many developers are interested in it - not only its original designers have a strong lineup, but also the people involved in modifying the source code. This is likely to help go language find its own direction and open up a new direction of system programming.
