Bitcoin blocked chain
but what I want to emphasize is that bitcoin mining is now a very professional instry. Although ordinary people can dig, the cost is much higher than that of professional mining, so it's better to buy money directly.
it has practical value for various instries, not only in the financial field, but also in supply chain management, intelligent manufacturing, culture and entertainment, financial services, health care, IP right, ecation, Internet of things, sharing economy, communication, social management, charity and public welfare, social employment, and E-government
at present, the era of blockchain 3.0 has come. From 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, and blockchain technology will have more new development.
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 uniqueWhat 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

Mining miners are also very scarce, especially iron ore. if you want to be self-sufficient, mining and selling iron is a good choice, suitable for civilian players
hemp picker is one of the most popular occupations. Whether it's making bandages or cloth, it needs a lot of hemp. At the same time, the medium-term camp upgrading also needs a lot of jute materials

the fee is 5500 yuan / academic year, and the accommodation is 1200 yuan / academic year. Art is more expensive.
It should be noted that the fire of bitcoin has made many counterfeit coins spring up like mushrooms. Without technical knowledge, the stability of counterfeit coins can not be recognized, so we need to be extra careful; More importantly, many pyramid schemes and scams are disguised as "virtual currency". We must be careful to identify them and avoid being cheated
