Is blockchain recognized by the world

1. blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.

2. Give him some money, find he has a lot of money, ask him to go again tonight, he also agreed. Hindley is ridiculous

bitcoin:

is an electronic currency proced by open-source P2P software. digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin."

bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. Since bitcoin was born with an algorithm, it was stipulated from the beginning that all bitcoins in the world would not exceed 21 million bitcoins. Because bitcoin is not regulated by the government, it is not subject to inflation constraints and external control

people use the computing power of CPU and CpG to "mine" to unlock the new bitcoin. To put it figuratively: bitcoin is equivalent to a gold mine created by people using computers. The setting of this gold mine is limited. The upper limit is 21 million bitcoin. People dig out bitcoin one by one just like miners using the principle of CPU computing

the principle of bitcoin, the distributed characteristics of P2P and the design without central management mechanism ensure that no institution can control the value of bitcoin or create inflation. This decentralization makes it a more secure and value preserving "virtual currency"

But in fact, netizens, as well as traders and investors of bitcoin, do not see one of the biggest drawbacks of bitcoin: bitcoin is not unique

What do you mean? We think that bitcoin is the only one with a cap of 21 million, which seems to have the function of preserving value. But the principle of bitcoin algorithm is not only applicable to "bitcoin", a kind of currency from Japan. Every computer engineer can develop the corresponding algorithm, make a man-made gold mine, and control its upper limit. In this way, every country, every region and every person can develop countless algorithms. Then the market will be full of virtual currencies such as "bitcoin a", "bitcoin B", "bitcoin C", "bitcoin D", and so on. By that time, who are you going to invest in? You can create your own currency

this hidden danger is not a dream. In fact, it has already started. You can log on bitcoin's official website in China. You will find that in addition to bitcoin, there is now another kind of thing called "Yuanbao coin". This is an algorithm similar to bitcoin developed by a Chinese development team. It also has the same upper limit. The same people can't control it and dig Yuanbao coin out through "mining"

if they can do this, I believe many computer workers can also write their own "Yuan Bao coin", "gold and silver coin", "China bitcoin" and "Shanghai bitcoin". Bitcoin, as the first code to appear, has no credit support from the Central Bank of any country. It has value only because of the scarcity of 21 million. In fact, this scarcity does not exist, because everyone can develop the virtual currency code, and then people from all over the world can mine it. So what's the price of bitcoin? There are limited kinds of metals on earth, so each metal has different value according to its quantity and scarcity. But the bitcoin like code in the network world is infinite. As long as people are willing, they can create unlimited kinds of bitcoin code. Tell me, is bitcoin still valuable

blockchain Technology:

the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database

the essence of blockchain is to achieve the goal of decentralization and disintermediation through a new generation of data technology, so as to transmit value more transparently and efficiently. This kind of point-to-point verification will proce a new network "basic protocol" which is different from TCP / IP in the Internet era

blockchain shows us a world in which all assets will be digitized. In a valuable Internet, the transfer of assets will be as fast, convenient and cheap as the transmission of information today

the significance of blockchain is not the wealth of digital currency, but the value transmission of its technology itself. Therefore, Ma Yun has repeatedly separated blockchain from digital currency, and stressed that the extent to which blockchain technology will change the world is beyond people's imagination

difference:

blockchain is a technology, based on blockchain technology, there can be many applications

bitcoin: is one of the most popular and well-known applications

4. At present, the state has not yet recognized
some time ago, the state specially cracked down on this virtual currency
so we should be cautious in investing in virtual currency

5. What is BHT's new currency? Its full name is bit hot token. It is a new currency launched by the currency exchange. It was launched on November 3, 2018. What is new currency? BHT can be used to buy other mainstream currencies, such as BTC, and high-quality tokens of the project side.

6. At present, there are many domestic network mutual aid platforms, but there are still many problems. Now let's take the problems existing in the current network mutual aid platform<

shortcomings of online mutual aid platform

operation is not transparent
there may be problems such as platform fabricating mutual aid events to obtain users' funds

lack of credibility
the general carrier of online mutual aid platform is technology company, lacking supervision and public credit endorsement, Therefore, it is easy to be questioned

inefficient
the compensation process is slow
and the emergence of blockchain technology provides solutions to these problems. The network mutual aid application based on blockchain platform can maximize the absolute security of funds, protocols and information, and improve the risk control ability. As the current network mutual aid platform of Tongxin mutual aid blockchain says, there are at least several advantages:
the flow of funds is transparent
all the details of the flow of funds are recorded on the blockchain, and the data can not be forged or tampered with to ensure the authenticity and effectiveness of the data, and all regulatory units, public media, and the Ordinary users can view and supervise the rule execution at any time, which is efficient
all fund transfers are executed according to the open and tamper proof smart contract, and once determined, they can execute accurately, no one can intervene, no legal person can misappropriate or intervene, It improves the efficiency of rule execution
user information security
all personal sensitive information is highly encrypted and stored, unless authorized by the user, other people can not access and steal
services will never be down
network mutual assistance running on the public chain does not depend on whether a central server is online, It can ensure that the services provided will never be down.
although the CIRC has not yet clearly defined this instry, it still supports those who can solve the problem of network mutual assistance, and for the masses, if they can accept the platform of network mutual assistance and join it, it means that they recognize the network mutual assistance, while the blockchain technology can solve the shortcomings of the network mutual assistance platform, I believe it will be recognized and supported in the future.

7. Blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust in the past
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
cryptocurrencies such as bitcoin, Puyin, Ethereum and dogcoin are just an application of blockchain.
