Blockchain giants

1. 1. digital currency trend maniac: 2. Head Wang's blockchain diary, 3. Currency grandfather, 4. Daily currency reading, 5. Xiaoju blockchain. These are the five best we media in the blockchain instry

2. There are a lot of development companies in this area, but we must pay attention to safety. Blockchain is also a technology supported by the state, so many development companies have joined in. Recommended here: Sichuan Huashang Jusheng Technology Co., Ltd. With more than ten years of experience in Internet technology research and development.

3. Zhu pan of beecool is a blockchain community and investor with high reputation.

4. Blockchain is composed of a series of block links generated by cryptographic algorithm, so it is called blockchain
each block is filled with transaction records, and the blocks are connected in sequence to form a chain structure, which is the blockchain ledger
blockchain technology divides the data to be stored in the database into different blocks. Taking bitcoin as an example, when miners generate new blocks, they need to calculate the new hash value and random number according to the hash value of the previous block, the new transaction block and the random number. Each block is linked to the back of the previous block through specific information, and connected in chronological order to present a complete set of data. In other words, each block is generated on the basis of the previous block data, which ensures the uniqueness of the blockchain data
each blockchain database is essentially an event chain connected in chronological order, which uses the cryptographic mechanism specified in the protocol for authentication to ensure that it will not be tampered with or forged. With the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid
there is no distinction between mobile and non mobile end in blockchain, and if there is one, it is also a gimmick.

5. The application of blockchain is token. It can be said that digital currency can make money, but it varies from person to person. Digital currency is an investment proct in China, and there is a great risk
in the digital money market, there are some people who make money, but there are also many people who lose money. Those who lose money eventually cut the flesh and leave the market, and those who make money at the beginning also slowly cut the flesh and leave the market.
especially those who invest in marketing money, more people lose money.

6. Chen Qihui, Yao Wenlong, Gong bin, Wang Wei, Duan Kai, Dong le and Xu Kun are all big names in the field of blockchain.

7. The maximum computing power is 68th / s. Shenma M20S
because the mining machine has a service life, in order to ensure that the computing power does not decline, it only provides a 2-year lease term

8. RMB is the legal currency of our country, and it is the currency symbol with purchasing power stipulated by our country's law. The relevant laws of our country have made detailed provisions on the monetary system, which are as follows: 1) the monetary material is stipulated, and the currency of our country is made of paper material. 2) the monetary unit is stipulated, and the monetary unit of our country is mainly yuan with Jiao Fen; China's RMB has unlimited legal compensation capacity (it means that the law stipulates that a currency has unlimited payment capacity, no matter how much it is in each payment, and no matter what kind of payment it belongs to, the other party shall not refuse to accept, otherwise it will be regarded as illegal.) 3) it stipulates the issuance of currency, China's currency is issued exclusively by the people's Bank of China. No other unit or indivial is allowed to print RMB. The issuance of RMB is not to issue as much as they want. This has its own law. This law is called the necessary amount of money or the demand for money, It is equal to the total number of goods multiplied by the total price of goods (the value of goods) divided by the circulation speed of money (that is, the circulation times in a certain period of time). For example, if the total value of goods in society is 1000 and the circulation speed of money in a certain period of time is 10, then the necessary quantity of money is 100. The central bank can issue money according to this quantity, If the central bank's circulation is higher than this amount, the money supply in the market will exceed the money supply, leading to currency devaluation, price rise, and inflation. After the issuance of the people's currency, the bank will issue it to commercial banks in the form of loans, Commercial banks then put money into the society in the form of loans. The issuance of US dollars is basically the same, because these laws are the objective laws of human economy and society, which are not transferred by one person's consciousness, and no matter what social form they are, they must abide by this law. The purpose of reserving US dollars is to provide guarantee for the stability of the value of RMB, In other words, once the supply of RMB in the market changes (because the market is constantly changing, the supply of money can not be completely consistent with the necessary amount of money), RMB can not automatically withdraw from the circulation field, but continue to be full of it, This requires a currency that can be generally accepted by all countries in the world, and the US dollar is the most acceptable currency for all countries in the world. With the development of China's economy, foreign trade is developing rapidly. In this case, we should have sufficient foreign exchange to ensure the smooth progress of our foreign trade
