The difference between quantum computing and blockchain
in the future, jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data.
Blockchain technology is a new technology derived from the development of bitcoin economy, blockchain technology can effectively serve the bitcoin economy , they are interrelated. Bitcoin is a kind of virtual currency, which only circulates in a specific network economic environment, blockchain technology can not only be applied to the economy, but also can be used in all walks of life , which is their difference
Blockchain technologybecause blockchain technology is still a new proct at present, it has no accurate or definite definition and concept. In short, blockchain technology is a mode of data encryption management, which can protect data to a great extent. Blockchain technology is characterized by decentralization, openness, independence, security and anonymity. Its characteristics well adapt to the requirements of information protection and information disclosure in all walks of life. On the one hand, it ensures the security of data and avoids the interference of subjective emotions and system failures. On the other hand, data indivials can decide whether to hide their detailed information in the group to the greatest extent, so as to achieve the purpose of privacy protection
At the same time, there is no doubt that the blockchain technology is still in the state of preliminary development. The social understanding of it is not deep enough, and scholars are still in the stage of continuous exploration. Through the correct use, blockchain technology will bring many positive effects to the societyblockchain originates from the underlying technology of bitcoin and is the blockchain technology of Internet. IP is connected by blockchain technology to form distributed accounting. It is not easy to tamper with and decentralize
code chain technology is the code chain technology of the Internet of things, which superimposes the Internet of things IDS one by one in a two-dimensional way to form personal records. The application of "code chain" technology will bring more efficient link forms of "people to people", "people to things" and "things to things"
Introction to code chain:
"code chain" refers to a "two-dimensional code chain" formed by using a smart phone to aim at the "two-dimensional code" and "scan", that is, to "generate a new two-dimensional code containing the scanner's DNA" and access to the "service". The whole process can be traced, supervised and managed
"code chain technology" is the most widely used two-dimensional code "scan" payment technology
code chain technology can realize more efficient link form of people to people, people to things and things to things
Introction to blockchain:
blockchain is an important concept of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
the difference between code chain digital currency and blockchain digital currency:
the difference between "code chain digital currency" based on code chain technology and the existing blockchain digital currency is that "code chain digital currency" is based on the control of property rights, and uses "intelligent two-dimensional code" as the medium to transform the contracts of various instry chains into divisible, tradable, transferable, exchangeable Traceable "smart contract" and real right exchange within the code chain alliance. In the code chain monetary system, "intelligent two-dimensional code" means "SGR". That is to say, each commodity corresponds to a "smart QR code", and this "QR code" represents the "special reference property" of the commodity. Through special reference to the exchange of property rights, the exchange of goods (barter) can be realized. This two-dimensional code, which represents "special mention of property rights", can be used as the carrier and payment means of digital currency at the same time, and payment can be completed through "two-dimensional code scanning".
Blockchain and artificial intelligence are the next era
There is a good combination between the twoblockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
artificial intelligence, abbreviated as AI. It is a new technical science to research and develop the theory, method, technology and application system for simulating, extending and expanding human intelligence
Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and proce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Since the birth of artificial intelligence, its theory and technology have become increasingly mature, and its application fields have also been expanding. It can be imagined that the scientific and technological procts brought by artificial intelligence in the future will be the "container" of human intelligence. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human and may surpass human intelligence At present, blockchain technology can be divided into three versions At present, in the first three versions, there are some problems, such as the lack of decentralization, low scalability, the mismatch between the incentive of the blocker and the best profit of the whole network, and the network always runs at the maximum capacity, such as bitcoin and Ethereum, which affect the efficiencyVelas combines the two to develop a public chain that can learn and improve itself
Velas enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and concts self-learning and self optimized public chain, aiming at improving the security, interoperability and high scalability of transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed
technically, Velas has integrated functions and services such as cross chain payment, multi signature wallet supporting multi currency, anonymous transfer, etc. Its Ecosystem focuses on all application scenarios covering transaction and payment, such as exchanges, multi signature wallets, merchant platforms, etc. after AI is fully connected to the system, the transfer fee can be completely exempted
and complete decentralization through AI enhanced dpos (aidpos) & gt; AI chooses who to mortgage the token according to the needs of blockchain & gt; Velas only blocks when needed & lt; Between every 1 second and every 2 minutes & gt& gt; Scalability (up to 30000 TPS) & gt; Block procers are selected by artificial intuition< br />
in fact, in the real world, even if quantum computing is implemented, if the topology of the whole network is still in accordance with the existing model (the infrastructure will be updated for many years), quantum computers can only greatly improve the computing power on a few nodes and obtain accounting rights, So basically, quantum computing should be safe before it reaches everyone's personal computer.
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 fortunefuture 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:

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.
