How does blockchain see K-map

1. Moving average, Ma for short, originally means moving average. Because we make it linear, it is generally called moving average, Ma for short. It divides the sum of the closing prices of a period by the period. For example, the daily Ma5 refers to the sum of the closing prices in five days and then divided by 5. Moving average was proposed by Joseph E. Granville, a famous American investment expert, in the mid-20th century. Moving average theory is one of the most widely used technical indicators today. It helps traders to confirm the existing trend, judge the trend that will appear, and find the trend that is about to reverse<

MACD is called the moving average of similarities and differences, which is developed from the double index moving average. The fast line dif is obtained by subtracting the slow index moving average (ema26) from the fast index moving average (ema12), and then 2 × Fast line dif-dif's 9-day weighted moving average (DEA) obtained MACD column. The significance of MACD is basically the same as that of double moving average, that is, the dispersion and aggregation of fast and slow moving average represent the current long short state and the possible development trend of stock price, but it is more convenient to read. When MACD turns from negative to positive, it's a buy signal. When MACD turns from positive to negative, it's a sell signal. When MACD changes from a large angle, it means that the gap between the fast moving average and the slow moving average widens very quickly, which represents the change of a market trend.

2. Guizhou has released some standards, such as the quality model and key elements of blockchain system, the implementation process of data asset transaction of blockchain, the terminology and basic requirements of the implementation process of targeted poverty alleviation of blockchain, etc. now many local blockchain applications have been implemented. Our digital money package is also an application of blockchain technology, and now blockchain applications have been implemented one after another, Changsha high tech Zone has launched a SMIC blockchain service platform project, which is based on the blockchain + public service mode, and is soliciting enterprises to join the chain.

Blockchain is a kind of technology, which solves the core "trust" problem in the market economy and reces the trust cost between strangers to a very low level

there is one crucial thing in the market economy, which is "trust". Without trust, no deal can be established. When you go to LAICHANG to buy vegetables, if you don't believe that the pesticide content in vegetable is up to the standard, you won't trade with that dealer; If you buy a bottle of water in a small shop, the clerk will not sell you the water if he doesn't believe that the money you give is real

the traditional small-scale peasant economy is acquaintance economy, and the transaction scale is limited to people who are familiar with each other nearby. If an acquaintance deceives you, he will lose your social relationship and damage his reputation in the whole circle of acquaintances. We believe that acquaintances are less likely to cheat us than strangers

therefore, once we are beyond the scope of acquaintances, we need to use a high cost to identify whether a stranger will cheat me and how to avoid the risk of being cheated. This situation will hinder the transaction and restrict the transaction

in addition, different races, nationalities, cultures, religious beliefs and so on will naturally have this kind of trust problem

in the market economy, why can there be so many transactions between strangers? Because of the birth of a new mechanism to solve the problem of trust in strangers

so far, the most important mechanism to solve the trust problem is the "trust intermediary" organization and mode

as long as you and strangers trust a third-party organization, the trust problem between you can be solved through this third-party organization

this third-party organization, we call it trust intermediary. Both the government and the bank are trust intermediaries

you can sell the goods you have worked hard to proce to a stranger in exchange for a stack of RMB banknotes. It's because the credit of the note issuing bank and the guarantee of the authority of the government guarantee the currency value and effectiveness of the banknotes. Otherwise, sell things, in exchange for a few ordinary paper, who would like to

in the era of global village and Internet, the people who buy your things may be strangers who will not meet and thousands of miles away. Trust is lower, so Alipay assumes the role of trust intermediation. Buyers first pay the goods to Alipay's account. When they receive the goods, they confirm that they are OK, then they agree to sell the goods to the seller. Taobao and other e-commerce have been booming rapidly in just over ten years

trust intermediary is in a central position in the transaction system. All transactions should solve the trust problem through it

However, the cost of trust intermediary itself is often huge

as a trust intermediary, how much transaction tax does the government charge each year? What is the most profitable instry? Financial services. The annual profits of Alipay's ant suit are over ten billion. p> What does this mean? Both sides of the market actually pay a huge trust cost

if there is any way to cancel or greatly rece the trust cost, the transaction cost of the general public can be reced, and the profits can be greatly increased

so in the Internet era, blockchain technology is on the stage

it allows the trading party to get rid of the intermediary, solve the problem of trust among strangers, and greatly rece the cost of trust

the blockchain can be expanded on a large scale, the data is open and transparent, the data of each client is consistent, and even if some clients are destroyed, the data security will not be affected. These highly reliable technical features can solve the trust problem of strangers with low cost

this technology can be extended to all fields that can be digitized, such as digital currency, payment and clearing, digital bills, proof of rights and interests, credit reference, government services, medical records, etc

in the medium and long term, blockchain will be a revolutionary technology, which will bring about great social changes like the existing Internet, and has great investment value and money making opportunities

in the future, the companies that can combine blockchain with different scenarios to promote applications may be the next group of bat, the next Google, Microsoft and apple

as the first practical application of blockchain technology, bitcoin has been widely accepted and used all over the world. Millions of users and tens of thousands of merchants have accepted the payment of bitcoin as a digital currency, and the exchange value of bitcoin as a currency is growing. Even e to the consensus that the total amount is fixed and the long-term value is bullish, bitcoin has become a hedge asset similar to gold, and the price has skyrocketed

4. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
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
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. 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.

5. Buy one or two books about blockchain, and you will have a general understanding of blockchain technology and development prospects. But we should also pay attention to real-time dynamics. China has done a good job in this field. There are weekly, monthly and other instry analysis reports, which are relatively authoritative in China.

6. Decentralized, open and transparent payment and collection technology. If you don't understand, I'll take you to make one. Completely free blockchain digital currency.

7. Now the blockchain is flying all over the world, and it's hard to tell whether it's true or not.
the network itself has a large number of users, and the technology can certainly keep up with it. As for how, I don't know

8.

There have been blockchain projects launched, such as utispace. Blockchain is the general trend of the tuyere project, but in the selection of blockchain projects, we must shine our eyes, we must find a team with technology, application landing and real down-to-earth work. Otherwise, it may come to nothing, because since it is a trend, naturally there are a lot of speculation and fraud projects

here, we mainly introce utispace, the first blockchain distributed storage project with perfect technology and real application in the world

give a brief introction to utispace: is 5g here? Have big data, artificial intelligence, wearable devices, Internet of things and AI entered our lives? Is the phone running out of memory

stuck

the high-speed information flow inevitably needs infinite storage space, but the current storage space is never enough

for example, the storage space of 4G mobile phone determines the price of mobile phone, but what about 5g mobile phone? More to 10 times the demand for 4G space storage, the price will be expensive

where there is demand, there is market. In the past, we need to build a big data storage base station for big data storage. The cost is very high. It costs 10 billion yuan at any time, and the security is very low (the base station will be hot and prone to fire and earthquake, what should we do? If hackers attack all data, they will be paralyzed). In addition, no matter how big the base station is, its storage capacity is limited, and it can never meet the demand of doubling the amount of data generated by the market, resulting in a large number of useful data homeless. At present, 67% of the data has been deleted, which is a great loss

so who can solve the data storage with large storage, high security, low cost and low energy consumption

today, the decentralized distributed storage space of China's own brand utispace, together with the digital pulse chain Laboratory of Zhejiang University, has solved this worldwide problem. Thus, it takes the lead in occupying the big cake of distributed data storage
