How to look at the emergence of bitcoin

1.

The emergence of bitcoin is based on a set of "payment system", and its value was first born because of the choice of "forced and helpless". In the later stage, bitcoin develops in the direction of digital assets and digital gold. In addition, there is a blind area of legal supervision, which gives opportunities to some lawless elements and people and institutions who like to speculate, In addition, some people dream of becoming rich overnight, which sets off a prosperous currency circle. As the world's first digital currency, bitcoin's value has soared tens of thousands of times

After the birth of bitcoin, people didn't understand it at first, but with the development of technology, many people began to preach and preach its value when they knew how to use it, and it was in line with the needs of some people and institutions, With the participation of capital and institutions, it has been pushed to a new height. Combined with the rise and fall of the price of bitcoin in the past five years, almost every big fall has been caused by frequent cutting of leeks. Due to the lack of supervision and extremely serious privatization, many people have not made a fortune overnight through the coin circle, but lost everything

2. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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 money 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

warm tips: according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law

historical background

bitcoin is one of the first currencies to realize the concept of "cryptocurrency". In 1998, Wei Dai first expounded the concept of "cryptocurrency" in cypherpunks mailing list. Based on the basic concept of money, which is used to pay for goods, services and debt or any form of records in a given country or economy, bitcoin is a new form of money. Its original design is to integrate the idea of not relying on the central authority, using the principle of cryptography to control the issuance and transaction of money
in 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto claimed that he had transferred to other affairs and left the project. The creator of bitcoin never revealed his true identity, but left his invention to the world. Today, the origin and motivation of the invention of bitcoin is still a mysterious story
since 2010, many developers have devoted themselves to this project, and the bitcoin community has grown rapidly. Between June and July 2011, bitcoin suddenly gained media attention, leading to large-scale buying. The resulting bubble led to the continued decline in the price of bitcoin in the second half of 2011. After that, the price of bitcoin graally rose to the height of 2011
in order to regulate, protect and promote the development of bitcoin, the bitcoin foundation was established on September 27, 2012. Nowadays, with the increasing number of bitcoin users, bitcoin economy is developing rapidly

technical features

any network like bitcoin has the following basic features:
bitcoin can be transferred between any node of the network
the transaction is irreversible
the use of block chain avoids the occurrence of double consumption
the transaction will spread out in a few seconds and pass validation in 10 to 60 minutes
transaction processing and currency issuance are carried out through mining
bitcoin can be received at any time whether it is online or not<

economic rules

the whole bitcoin network jointly implements the following rules:
the total amount of bitcoin issued is about 21 million
a bitcoin can be divided into 8 decimal places, with a total of about 21 × 1014 monetary units
transaction costs are very low and most of them are free

statistics

bitcoin network has been running continuously for more than 48 months. In the past year, bitcoin's security features have attracted attention and developed significantly. As of April 2013:
the longest block chain has more than 232000 blocks
one of the largest distributed computing networks in the world, with more than 65 trillion hashes per second
there are 50000 transactions every day, with a total amount of several million US dollars
the total value of bitcoin in circulation exceeds US $1.3 billion
there is only one major security incident in the protocol, which was resolved in August 2010

4. Bitcoin is a P2P network. Just like the familiar BT download mode, in order to keep the network running, we need to always keep someone online to upload and share data with others. Therefore, the publishers of BT seeds often ask the sowers on the forum to be "Sowers", but in fact, BT seeds are often broken, and people are selfish, You can't ask everyone to contribute their resources for free

from the perspective of network technology, that is to say, the generation of bitcoin is primarily for the continuous and safe operation of the network, which can not be used to measure the development speed of P2P virtual economy. Just like collectibles, people have proced bitcoin not to make it circulate and trade like money, but as a sign of geek's contribution to inspire people. But now people misunderstand the original intention, the proction of virtual currency itself needs cost, and people's enthusiasm will add up the cost infinitely. As a result, the price ratio between real money and virtual money is becoming larger and larger, creating the current situation

and the bitcoin network, like the BT download, needs "miners" to contribute their computer resources for calculation to ensure the operation of the bitcoin network. If the people who contribute resources like the BT download can not get the benefits, the bitcoin network will collapse. So the issue of bitcoin is designed that whoever contributes computing power to keep the bitcoin network running can get the fee paid by the network - bitcoin

As for the significance of bitcoin, bitcoin, as a currency specially designed for the Internet, is essentially a payment solution. Modern currency has never been global, let alone completely free circulation. This is the contradiction between the existing monetary system and the Internet, and bitcoin is designed to solve this contradiction, Let money become a string of data to follow the circulation of the whole network

bitcoin has a more direct significance in recing the transaction cost of Internet trade, especially small transactions, making the original unprofitable transactions profitable, and enabling the original transactions that could not be concluded e to payment to be concluded

5. Money, also known as the general equivalent, is used as the basis of transactions. When countries and institutions issue currency, they need something to support its value. For example, in the gold standard, gold was used to guarantee the issuance of currency; Later, it broke away from the gold standard and was guaranteed by national resources and national reputation
therefore, "bitcoin" is converted into value by "CPU power and time consumed" in host computing, which means that because miners need "so much power and time", the bitcoin g out will be worth so much money

in fact, the metaphor of this sentence seems wrong now. Suppose there is only one computer in the world to dig bitcoin slowly, or you can dig it all out. Therefore, the price of bitcoin depends more on belief (I believe that more and more people will use bitcoin, and bitcoin will be accepted by more and more people), as well as the capital inflow generated by belief.

6. Jiangsu Rongze e-license blockchain platform and ZTE Shenzhen's shared government platform are excellent platforms. Tencent, Jingdong and ant have also made efforts in this direction, and there is no specific platform to be implemented.

7.

Virtual currency, like bitcoin, is emerging again. What do you think of the emergence of virtual currency? For the emergence of virtual currency, I have three views:

1. the emergence of virtual currency is a trend of market development. In fact, many times, the emergence of some goods is e to the market, and also inseparable from the development of the market
2. the emergence of virtual currency brings business opportunities. In any case, the emergence of virtual currency can make people invest, and many people can make profits from it
3. the emergence of virtual currency brings more competition, and the emergence of virtual currency will make more people compete, and also make the competition more intense < / OL >

   in fact, there is a growing trend in the development of virtual currency, and more and more people want to invest in virtual currency. Many people have a certain investment from virtual currency, and they get a certain return, but the emergence of virtual currency also brings some risks

   First, the emergence of virtual currency is really e to the development of the market

   in fact, I think it is because of the rapid development of the market economy that virtual currency has the opportunity to appear. Because if the virtual currency can appear based on the development of the market, it will make more people pay more attention to the virtual currency, and also enable more people to invest in the virtual currency{ RRRRR}

   the emergence of virtual currency is a double-edged sword, good and bad

8. In general, the salary card can be a class II card. The class II card only has restrictions when you transfer money or withdraw money, and does not affect the employer's salary.
