Blockchain 21 million
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
for example, bitcoin was invented by Zhongben Cong in 2009, and the total number of bitcoin was only 21 million. By participating in the proction of blocks and providing proof of work (POW), we can get the reward of bitcoin network. Mining is the process of packaging and confirming the transactions in the bitcoin system over a period of time, and then recording them on the block

what is moving bricks
when it comes to "moving bricks", you will think of migrant workers or various online jokes, but today we only discuss "moving bricks" in the blockchain market
to describe "moving bricks" in vernacular is to make profits by using the price difference between different exchanges. The same currency has different prices in different markets. Buy it in a cheaper place and sell it in a more expensive place. The middle price difference is your profit
for example, the price of bitcoin BTC is $4000 on exchange a and $4100 on exchange B. after a buys BTC, it can be sold to B and each one can earn $100. This process is called "moving bricks"
blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcThe attachment of the complete works of the universe has been uploaded to the network disk.

for those who care about this book, green is here. I'm really sorry, because there are so many green things ring this period, so it can't be updated in time. Please forgive green. When green has finished all the things, it will come to update at the first time. After all, green is the first time to write a book, but also an amateur author, so you can also cool the difficulties of all cool green. Green is here. Thank you very much.
