Bitcoin blockchain 36

1. bitcoin is a kind of virtual digital currency proposed by Nakamoto in 2009. It is characterized by no centralized issuing institution and a fixed total of 21 million pieces. It is not a one-time issue and needs to be proced by miners. Due to the decentralized structure, trust needs to rely on cryptography and consensus mechanism technology to achieve
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.

2. Bitcoin blockchain is a bitcoin blockchain? No, the block stores the transaction. In the early stage, you will get a coin if you successfully build a block. In the later stage, you can only get the fees paid by the exchange. A currency is a string of digital signatures. It is a digital signature sent by the last owner to the receiver. Everyone can see who owns the currency from the transaction
does each node have complete blockchain data? You mean a user node? A user node needs to keep the of the block head of the longest workload proof chain, so it knows the data of all the block heads. It can move forward to know all the data on the block chain, but not all of them are saved. A block header is very small, only 80 bytes, which can be saved completely, because the generation of nodes is very slow. Even with the passage of time, the amount is not too large now.

3. With the advent of bitcoin, a new technology, blockchain, has come into the public view. What is the relationship between bitcoin and blockchain? The simplest understanding is: blockchain is the underlying technology of bitcoin, and bitcoin is the first generation application of blockchain. Therefore, we often see such a saying that "bitcoin represents the era of blockchain 1.0"

bitcoin is regarded as the first generation application of blockchain technology and the most thorough application of its code testing. However, without bitcoin, there might not be so many people who knew about blockchain now. It can be said that bitcoin has greatly improved the "exposure" of blockchain technology

later, people graally found that the application value of blockchain is far more than bitcoin, but can be applied to many instries to solve the pain points of many instries; The idea of blockchain can also provide a lot of reference for the financial field, which is the real reason for the outbreak of blockchain.

4. Sintering machine is actually a sintering system, including civil engineering, which transports materials from the manufacturer. The ring sintering machine is suitable for small blast furnaces. Dingxin of Shanye and Dingxin of Shanxi are good domestic ones. They have blast furnace operation experience and can achieve good economic indicators. After all, the purpose of opening the plant is to make money.

5.

You can participate in it with small funds. Bijing is the next generation Internet outlet. The following is my investment experience in the past year. I hope it can help you

taking advantage of the holiday to relax physically and mentally, I took stock of the pits I stepped on and sorted out the gains and losses. My experience is as follows

1. In the early days, I believed too much in the big V of the coin circle and bought some coins from their platform. Now it is close to zero. I feel that I am really naive to believe their lies. In the face of the temptation of huge wealth, people can hardly stand the test. Of course, they can't get beyond it. However, if they don't accept what they say and do, they will lose their moral bottom line. They make a lot of money, leaving me shivering on the top of the mountain

two, the official account of the currency circle and all kinds of media, the judgement of the market trend is almost the same as that of the throwing dice. Of course, this is not to say that the media are totally irresponsible, or that they are not competent at all. In fact, some media are more reluctant to feather their feathers and do their best to analyze projects for fans and judge the trend. But don't forget, in essence, the market is unpredictable, otherwise it will not be called the market. Makers and leeks are always playing cat and mouse games. The prediction of the media will often provide the smart makers with reverse action guide. When most media are optimistic about the market, it is also the time for the makers to raise their sickle; When the media generally think that the market needs further exploration, the makers may be stealing Yu Jiancang, which is not difficult to understand, because the media acts as the opinion leaders of leeks

Third, the current market mainly shows the characteristics of investment gold plate, with speculation as the main factor, and the real block chain value investment has not been reflected. The performance is that almost all counterfeit currencies are linked with the rise and fall of bitcoin. Why bitcoin? Because there is no other standard to rely on. If there is no killer application, this linkage effect is difficult to break, and there will not be a real bull market in the currency market. The killer applications mentioned here are not like Ethereum, such as issuing currency and being an underlying public chain, but have real landing application scenarios, which can link the virtual digital assets on the chain to the supply and demand of real scenes. At the same time, DAPP should have a good user experience and be accepted by the public outside the coin circle. In this way, digital currency will have real support, and the development of blockchain will usher in the spring, otherwise it will be speculation

Fourthly, we often set out from the historical phenomenon to form the expectation of the future. In 2017, some counterfeit coins went out of the market 100 times or even higher, so I always felt that the counterfeit coins in my hand had gone up three or five times after I bought them, which was not enjoyable and not in place. As a result, I didn't sell them in time, so it was rotten in my hand. To analyze, this is not the time. At that time, there were less projects and more funds. At this time, there were more projects and less funds. The situation is just the opposite. Ignorance and greed are very dangerous. Since 2018, with the big V's profits leaving the market, the funds in the market have shrunk significantly. Even the rising market is the game of the original funds in the market, and the profit-making effect is getting smaller and smaller. The funds outside the market are waiting and waiting. Only when there is a wealth making effect, can the funds outside the market have the impulse to come in

Fifthly, new ways of playing appear constantly. As the effect of making money is getting smaller and smaller, new leeks become old ones. Traditional harvesting methods are difficult to cut down the order. Only by making some innovations can leeks flock to the market. Fcoin trading, mining, firebull video and so on, has made a small number of people rich and at the same time, it has made a large number of people miserable. In essence, these projects are all capital games of drum beating and flower passing, with no change in dressing or soup. The earlier we participate, the more accounting we have. When we wait for leeks to participate, they are basically in the middle and late stage. If we put money in, they will be harvested. I, fcoin, because I participated earlier and made a small profit, but firebull participated later and was cut as soon as I went in. Fortunately, I only tried to cast a little bit

Will the market rise again? The answer is yes. In two ways. On the one hand, blockchain is the trend in the future, which has formed a consensus. It is said that there is a rule that can prove whether a technology can become a trend in the future. It depends on whether the number of articles published on this technology can multiply every year. Blockchain is fully in line with this rule. On the other hand, as mentioned above, the current market is mainly capital market. So even if blockchain is not the future trend, it will still come out of a good market. Because the characteristic of the capital market is that when the capital enters the market, the market will rise, and when the capital withdraws from the market, the market will come down, and there is no reason for the capital to enter or leave the market. At present, there are not only retail investors, but also large investors and institutions in the market. What is covered is not only leeks, but also makers who cut vegetables but did not cut them. No matter who is in the currency circle, there is only one purpose, that is to make money. If the market doesn't rise, there will be no big money making effect. If it falls for a long time, it will rise. This is an irrefutable law. Of course, whether indivial investors can make money depends on their own fortune

future plans:

first, the best policy. Strictly control the position, adjust the layout and stay away from the air currency. Position control is always the first and the lifeline of investors. After losing money, we realized the importance of position control. Now I really regret that if I didn't enter the warehouse, I wouldn't be so deep. So far, decisively clear all the air projects, and more or less free up a little money. Then, select a few high-quality projects to make fixed investment, if the funds are not enough, a small part can be disbursed from the daily income. To do this well, we need to make up an important link, that is learning. In the past, I didn't know whether the project was good or bad, but I didn't learn enough and my skills were shallow. It's better to focus on study than on reading the market, consulting the public number and asking for information. The accumulated knowledge and skills are also a kind of wealth, and no one can take them away. It is necessary to learn the basic knowledge of economy, finance and investment, as well as the knowledge of blockchain. I have read some books (general knowledge of economics, one course of economics, Xiangshuai's finance course at Peking University (I get a subscription, but I can't provide an electronic version), buffet's rule, buffet's Guide to read financial report, blockchain technology guide, decoding blockchain complete works), and give the link address (link:

Second, the medium strategy. Do oversold rebound. Small earning effect does not mean no earning effect. We must invest small funds in one or two projects, and we must go in and out quickly when there is a sharp drop and most people feel panic. We must not be in love with war You can focus on one or two big public accounts to judge the panic of the market.)

Third, the worst way. Make a wool party. On the premise of not wasting energy, it's OK to get candy and some welfare. In the current market, grasshopper is also meat. The traditional way of getting candy is too cumbersome. We found two candy delivery platform projects, one is the fulcrum:

the other is the ant Miner:

the former airdrops all kinds of candy from time to time, and at the same time has the social attribute of the community. It operates in a systematic way and obtains the strategic investment of coin safety and fire coin; The latter is a brand new candy game platform of candy world, which accumulates candy in the form of chicken laying game. It is reported that it has just won the strategic investment of gbls (Global sleepless blockchain Leaders Summit)

in addition, some dapps in the testing stage are also worth a try. Anyway, it doesn't involve any energy. It's just a way to relax after work. Fighting video (IOS version: https://fir.im/51ds Android version: http://a.app.qq.com/o/simple.jsppkgname=com.xysk.mvpart.douxi , invitation code: wn4viz), focusing on the vertical segmentation of professional artists, fans can accumulate star power and sign in every day to get stars. Stars can be exchanged for prizes or sold in private. October is the right time to go online

6. Bitcoin market can now be seen on professional software, such as the coin card I use now. I think it's very good. Most of the data are available and updated in a timely manner. I recommend you to download and use it

7. Bitcoin is a kind of digital currency based on blockchain technology, and the simple understanding of blockchain technology is an electronic currency account system realized through point-to-point. It can record every transaction record of bitcoin through the network, and it is decentralized. No one can change it without authorization, so it has a very stable security guarantee for its holders. Blockchain is an incredible great technology in Internet finance. Its inventor "Nakamoto Tsung" has just been nominated as a Nobel Prize candidate by the economic and financial circles.
