Why is my mandatory currency not produced
The following is the distribution chart of computing power:
the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing
however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets
in short, it is a redistribution of computing power driven by interests.
For example, when many enterprises choose servers, they will consider the difference between blockchain servers and traditional servers? The following is a brief analysis
to be exact, the blockchain is a technical model, and the server is a type of hardware resource. There is no contrast between the two. However, if we insist on the difference, we can also see the difference and connection between the two
to say the difference between the two,
the biggest feature of blockchain is decentralization, such as bitcoin, the most typical application of blockchain. Bitcoin is independent of any third party's decentralized currency. There is no centralized issuer. It is generated by the calculation of network nodes. Anyone can run bitcoin client software on the computer to participate in the proction of bitcoin. No matter where they are, anyone can dig, buy and sell bitcoin
all nodes of the blockchain are distributed in different places, and each node is maintained and managed by itself. It does not need centralized construction, but also needs special management and maintenance, which can make full use of idle resources. Due to the distributed characteristics, the system is difficult to destroy, such as bitcoin. Even the most powerful people or organizations in the world can't destroy the bitcoin system based on blockchain
traditional server is centralization service
traditional centralization server, such as WeChat, Alipay and so on, are all responsible for providing services to all clients by the server behind the company, and the client acquires services from the server. If their servers are attacked and paralyzed, then your WeChat and Alipay will not be able to use them. For example, on May 28, 2015, Ctrip was attacked by unknown server, and its web version and mobile app could not be used normally
does the blockchain still need servers
to be specific, blockchain is also divided into public chain, private chain and alliance chain. The essential difference between the three is that they have different degrees of decentralization
that is, the public chain is completely decentralized. The above mentioned bitcoin belongs to the public chain. The private chain and alliance chain are not completely decentralized, and there is still a shadow of centralization
as mentioned above, blockchain is a technical model, and server is a type of hardware resource. The two will inevitably have a combination of applications
for example, the combination of storage type server and blockchain can use cryptography to ensure the security of data transmission and access, so as to make the storage server data more secure

however, spot trading is possible in China, but bitcoin has now restricted cash withdrawal. Arbitrage is nothing more than buying low and selling high to earn the difference. Digital currency Puyin takes 1 billion Tibetan tea assets as credit endorsement. Digital currency itself has the potential of appreciation, because Tibetan tea can appreciate.
it is recommended to learn about formal P2P networks such as xiaxinrong.com
On the front of the coin are printed "people's Bank of China", "1 yuan", Chinese phonetic alphabet "Yiyuan" and "2004" year number; The pattern on the back is children and the Chinese Zodiac elements, and "Jiashen" is printed below
in order to welcome the arrival of Jiashen year of the lunar calendar, the people's Bank of China announced on January 6, 2004 to issue a set of commemorative coins to celebrate the new year of the monkey. The front of the coin consists of Chinese and English characters of "1 yuan" and the year number of "people's Bank of China" and "2004" above the inner edge. On the back of it is a picture of a little boy wearing traditional Chinese clothes flying a "Kite" happily. Now the market price is about tens of yuan
every 10 minutes, the miners of the whole network work together to solve a problem and compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will soon be g out
in order to ensure the stability of bitcoin and dig out a block in about 10 minutes, Nakamoto Tsung designed that the difficulty of getting bitcoin from miners' mining should be dynamically adjusted every 2016 blocks (about 2 weeks). After the adjustment, the expected time for each block to be generated is 10 minutes
the current difficulty coefficient is about 480ph / s, which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer and generate a new block.
