Label printing blockchain

1. bitcoin is a kind of virtual digital currency proposed by Nakamoto in 2009. It is characterized by no centralized issuing institution and a fixed total of 21 million pieces. It is not a one-time issue and needs to be proced by miners. Due to the decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.

Recently, there are three popular concepts: blockchain, bitcoin and ICO

one is the blockchain, which is the blockchain in Xu Xiaoping's internal letter that "if it goes along, it will prosper, if it goes against, it will die"

the other is that it has been hyped for several years, and the price keeps going up and down, but some people have been advocating bitcoin that "each bitcoin will rise to $10000"

Another is the ICO, which Xue Manzi cheered and advocated a few months ago and later was strongly concerned by the regulatory authorities. On the night of January 12, the day before yesterday, the China Internet Finance Association issued an announcement entitled "risk tips on preventing disguised ICO activities", in which it named the digital currency "chain gram" (formerly "play guest currency") released by Xunlei, saying that it "replaces the legal currency payment obligation for the services contributed by the participants, which is essentially a financing behavior and a disguised ICO". As soon as the news came out, Xunlei's share price fell sharply in the early trading of us time on Friday

"bitcoin" does not solve any problems

besides bitcoin, Xiaotao has always been a loser of bitcoin, because in Xiaotao's view, bitcoin has not solved any new problems. In other words, what would the world lose without bitcoin today? Who and which transactions will be affected? The answer is that no one will be affected except the most special people. What are the advantages of bitcoin over existing currencies? Stable currency? Security? Low cost

the decentralization advocated by bitcoin is nothing more than evading regulation. For example, the goods between the two countries should have gone through the customs. The Customs has eight channels. Now you have an underground channel. Although the distance may be closer and many customs ties may be exempted, it is illegal. It is a typical Arbitrage Behavior to evade supervision. Solving one's own problems on the premise of harming social interests and order is not desirable and can not last

What's more, in order to obtain bitcoin, the huge "mining" workload consumed a lot of power and computer computing power, and did not create any value, which is a huge waste of social resources. It is said that the cost of digging a bitcoin has reached 3000 to 4000 US dollars...

"ICO" is a typical Ponzi scheme

as for ICO, the so-called IPO project with digital currency as the media, sticking to its own hot speculation concept, holding the idea that it is not ready to cash, or the idea that the feasibility is almost invisible, relies on a kind of digital currency that evades the supervision to let people buy and hype the price... This is a typical Ponzi scheme, or open a casino in disguise

there are many such cases in history. A few years ago, some people divided any painting into tens of thousands of shares, marked a price for everyone to buy and hype; Hundreds of years ago, the Dutch were crazy about tulips. A tulip price could buy a castle... Everyone knew that it was a bubble. They all knew that the bubble would burst, but everyone wanted to beggar the neighbour, hoping to get a.

before the bubble burst.

4. At present, there are too many currencies in the market, which can be said to be a mixture of fish and eyes, and as high as 90% of them belong to air currency. A former friend lost more than 10000 because he invested in one kind of air currency. Although the number is small, we should be cautious

5. A new resolution initiated by representative Adam kinzinger, a Republican from Indiana, has been submitted to the US House of Representatives, calling for a national policy on emerging technologies, including digital currency and blockchain technology
the resolution calls on the idea of bitcoin, but does not directly mention its name. Instead, it calls it "alternative illegal currency". Blockchain technology is the key point, which points out that this technology has the potential to "fundamentally change" the way trust and security are built on online transactions
but in fact, the United States has not taken action to formulate this rule. However, there is a global blockchain alliance R3 in the process of formulating the standard for the use of blockchain. Of course, blockchain is just a technology that can be used by anyone. In China, there is a project called decent, which is more avant-garde. It uses blockchain technology to create a decentralized content release, but it may encounter some problems in China.

According to a number of financial media reports, the queen of England seems to be very interested in blockchain technology. The reason is that the British blockchain Association, a non-profit organization, sent a magazine to the queen about blockchain research. The queen learned that this is the first open blockchain research journal to be printed and published at the same time for online reading. The magazine received a reply from the private secretary of the Queen's office, expressing her interest

so what is blockchain< I think it is a technology, a decentralized distributed ledger database, which is composed of different data I have the following views on this:

first, it is a technology

blockchain is a technology, but many people do not understand what kind of technology it is. For example, when shopping on an e-commerce platform, there are sellers and buyers, as well as this e-commerce platform, the blockchain technology is to replace this e-commerce platform

now a lot of technology updates have attracted a lot of people to invest in it. However, without understanding the whole technology itself, it is recommended to be cautious to avoid losing money

What do you think of this? Welcome to tell me in the comments section< strong>

7. Loudi began to explore the blockchain instry at the end of 2016. In a few years, Loudi has made several firsts, such as the first e-Voucher of real estate block chain in China, the first government affairs alliance chain in China, and the first officially listed block chain instrial park in the province, which also gives Loudi the label of "city of block chain". This year's Internet Yuelu summit will also be held in Loudi City. Let's wait and see.
