What are the prospects of blockchain?

The application of blockchain has extended to many fields such as medical health, education, charity, social management, and finance. The biggest advantage of blockchain is that it truly completes the construction of credit in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible. . The current blockchain is equivalent to the Internet 20 years ago. It is in its preliminary stage. In the future, it will definitely become a major part of the social economy and be used to benefit the people and society. Please wait and see!
Blockchain is an intelligent peer-to-peer network that uses distributed databases to identify, disseminate and record information, also known as the Internet of Value. The concept of blockchain was first proposed by Satoshi Nakamoto in his paper "Bitcoin: A Peer-to-Peer Electronic Cash System" published on the Bitcoin Forum in late 2008.
It is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and manipulate data.
Blockchain Investment
Blockchain investment is indeed one of the hottest investment methods in today’s society. Although blockchain seems to have just started, as such a novel existence, it It is indeed very unique. Many people don’t know what blockchain is. They only know that blockchain mining can make money, so they follow it in a fog. But to achieve a truly safe investment, I suggest that everyone still Understand it first, prepare well before taking action, and don’t fight an unprepared battle.
Blockchain technology does have huge room for growth in the future. Many people believe that it will be able to subvert many existing industries in the future. This is very important. This is the source of all your confidence. If you If you don’t recognize the value of blockchain from the bottom of your heart, then you are likely to be affected by some negative remarks and even doubt the entire industry, which will affect your entire decision-making and judgment.
If you just want to play casually or test the water, the chance of success is very small.
Once you are determined, be prepared and spend all your precious energy on research. When investing, you must do your homework! Never invest money without knowing what the project is about.
Finally, the blockchain is a new industry after all. It is currently in a mixed situation, and of course there are scammers. Therefore, when we invest, we must be careful and do not accept what others say. Bright eyes.
In addition, I still have to say,Investment is risky, so be cautious!

㈡ If the currency is to be cut off, where will the research and development of the leek blockchain go?

Conclusion:

1) According to the Tianyancha website Statistics of search results;

2) Since the industrial and commercial bureaus across the country have inconsistent operating standards on whether to advance "blockchain" in company names and business scopes, there may be a large number of companies actually carrying out blockchain. Technology research and development is not reflected in the name and business scope, resulting in the situation that it cannot be included in the statistical results.

Data shows that Guangdong, especially Guangzhou and Shenzhen, has accumulated a large number of blockchain companies. Compared with other provinces, Guangdong is almost unparalleled in attracting blockchain companies to settle in. The vast majority of these companies were registered within the past year.

In actual operation, if a company is established in Guangzhou and Shenzhen, it can be reflected in the name, such as Guangzhou ABC Blockchain Co., Ltd., or "blockchain technology development and application" can be added to the business scope. Or something like "Internet blockchain technology research and development services".

We believe that the application of blockchain industry will accelerate in the future. Its decentralization, disintermediation and anonymity will not only bring new challenges to enterprise management and government supervision, but also will It will bring more opportunities, realize data transparency, information disclosure, efficient management and operation, and gradually spread the physical implementation of blockchain technology to various fields.

㈢ Why is it said that domestic blockchains are all lies

Blockchain unexpectedly ushered in a big explosion in 2018, and the world was suddenly filled with "get rich overnight" ” dream and the “copper smell” of various virtual currencies, many people have plunged into the “sugar-coating” wrapped in blockchain. Will they realize their dream of getting rich in the huge bubble wave, or will they be treated like "leeks" and be cut off and bankrupt?

At this juncture, some people in the industry pointed out that "blockchain is a good thing, but the current domestic blockchain is all deceptive." Such people may have been "robbed" in the currency circle, and use this statement as a declaration of their poverty. He may also be a business leader in the blockchain circle. After reviewing the situation, he can see the various shortcomings of the current development of the blockchain and draw a comprehensive analysis and conclusion.

No matter who they are, this statement must come from the understanding of the current mixed status of the currency circle and the dim prospects of blockchain technology, and this is not difficult to understand. Binance and Huobi Pro, international large digital asset exchanges, have been repeatedly attacked by hackers, resulting in the loss of user assets. The website security mechanism preventsThe protection and maintenance of user information data are extremely unsatisfactory.

People who have suffered losses in the currency circle have turned their attention to the chain circle again. However, what disappoints users again is that although the chain circle has great prospects, due to immature technology, the blockchain in all walks of life The chain layout is still in the conceptual stage and it is difficult to take substantive actions. Not only that, even the blockchain media, which is based on fairness and facts, has been exposed to pay to recommend coins to induce investors, and promote ICO in disguise in the name of "private placement". In fact, it is an important service for "cutting leeks" tool.

Recently, the "blockchain+Tibetan tea" fund -raising fraud case of a blockchain company in Shenzhen has made the chain circles cool more, and the "world's first digital currency" is about to issue "the world's first original digital currency". The signboard defrauded more than 3,000 investors out of 307 million. However, blockchain companies of this scale and approach are emerging one after another, and it is difficult to distinguish the true from the false.

However, we admit that there are indeed deficiencies in the current domestic blockchain development, but can we generalize and label blockchain companies as "false"?

We should admit that every stage of development of emerging things is bumpy, and even criticized repeatedly. Just like the Internet 20 years ago, how many people could have predicted its earth-shaking development at that time? The same goes for blockchain.

Moreover, at present, domestic Internet giants such as JD.com, Tencent, Ali, etc. from all points such as financial trade, entertainment, leisure, logistics, and medical treatment; Blockchain has made breakthroughs in industries such as media and games one by one; the country has also introduced blockchain technology in strictly regulated industries such as energy and electricity; there are also Leou’s blockchain tourism layout and Ant Financial’s blockchain in Xiongan New Area Technical housing rental cooperation, etc. It can be seen from this that the blockchain layout is not a solo effort of unknown companies. Each has strong support from Internet giants and the government. Amid the collective excitement, how can the “scam” of blockchain gain confidence?

Although domestic blockchain companies are still in their infancy in terms of technology and application, this does not negate the blockchain itself and the overall situation of domestic blockchain. For example, "PeoplePeople's Daily said, "Blockchain has an unprecedented bright future."

Japan’s Financial Services Agency’s policy of renaming “virtual currency” to “crypto-assets”Opposed

The Japanese Financial Services Agency’s policy of changing the name of “virtual currency” to “crypto-asset” has been opposed by domestic industry groups.

In addition, many companies have already registered with "virtual currency", and changing the name at this time will inevitably lead to various problems.

㈤ If the virtual currency trading platform goes bankrupt, will the currency in it cease to exist?

After September 4, 2017, there will be no domestic Have some closed down? This is a very interesting topic, because with the blockchain craze, we often hear news about the disappearance of many small platforms in the field of digital currency.

Previously, the most famous one in history was the collapse of Mentougou in Japan. Recently, there have been rumors about compensation. In fact, after September 4, 2017, due to some policy reasons, some digital currency trading platforms were prohibited and many domestic digital currency platforms closed down.

The previously famous Yunbi, Bittel, Bitera, Jubi, etc. will carry out corresponding digital currency counting work, and the time set aside by each platform is different. The minimum seems to be three months, and most platforms will keep it permanently.

In other words, you have enough time to withdraw your own digital currency. In fact, many people now like to use their own electronic wallets. The platform was just a trading institution some time ago. The Binance hacking incident also served as a wake-up call for us.

For some small trading platforms, they are interested in very large transaction fees and currency listing platform fees. These small trading platforms will really take away all the digital currencies you have on the platform.
The correct way to protect your assets is to choose some internationally renowned large trading platforms and add digital currencies to your electronic wallet in a timely manner.

1. First of all, you must know that today’s digital currency trading platforms are all registered overseas. There are great risks in trading digital currencies. If the platform goes bankrupt, it will be difficult for domestic investors to protect their rights. I hope here Everyone should be cautious when investing.

2. Digital currency is just a string of codes, and each major platform has its own hot wallet. Generally, investors have two options. 1. One option is to place the coins in the hot wallet of the trading platform for easy trading and withdrawal at any time. 2. Another option is to withdraw the traded digital currency to your own cold wallet, and then transfer it to the platform when you want to sell it (cold wallets are relatively safe and have a low risk factor).

Reminder: Virtual currency exchanges, as many people say, are divided into centralized and decentralized exchanges, but most of them on the market are centralized exchanges. You only have a username and password. But in fact, all virtual currencies are in the wallet of the exchange, and all you see are numbers. If the exchange goes away, the website cannot be opened, which means that all your assets will no longer exist. But one of the most profitable people in the currency circle is those who open exchanges, which are similar to those who open casinos. You have seen a few casino operators run away, as long as you open an exchangeIt's not easy to run away. There are people on the exchange to support you. The reputational loss of running away is much greater than the actual loss. It is safer to put it on the exchange, but the most appropriate thing is to put your assets in a wallet that you can control. You can control your assets anytime, anywhere.

If the virtual currency trading platform goes bankrupt, will the currency in it cease to exist?

The digital currency trading platform has collapsed, but the currency still exists! It’s just that you may not be able to get your coins back!

This problem needs to be understood from two aspects:

1. Although the platform has closed down, the coins in the platform still exist!

First of all, the existence of a currency has nothing to do with the exchange, unless it is a trading and issued platform currency.

Digital currency is an important application of the blockchain, and digital currency is not generated through the trading platform. The trading platform is just a place to store assets and conduct digital currency buying and selling transactions!

Therefore, the collapse of the trading platform does not affect the existence of the currency itself, but the whereabouts of these currencies are unclear. Perhaps the exchange itself did not manage well and became insolvent, so it was used to repay the debt. It was stolen by hackers or transferred to other accounts.

In short, the existence of a currency has nothing to do with the exchange, unless it is a currency issued by the platform itself.

Take Bitcoin as an example to look at the creation of digital currency. Blockchain technology is a distributed ledger. The consensus of nodes determines the accounting of the public chain. The greater the computing power, the more successful accounting is. Bitcoin is a reward for miners who keep these accounts, commonly known as mining. mine! The process of recording these ledgers is actually the process of mining. Whoever records the most complete and fastest records will be rewarded with Bitcoins.

Therefore, the creation of Bitcoin lies in the accounting operation of the Bitcoin public chain and has nothing to do with the platform.

Therefore, whether the currency exists has nothing to do with the exchange. Of course, if you buy the own currency of a platform that is still closed, it may not exist! Even if the exchange goes bankrupt, these coins will have no value, which is equivalent to zero!

2. If the platform goes bankrupt, under normal circumstances, the assets (digital currency) you deposited on the platform will not be retrieved.

If you own digital currency, you will usually trade it and realize it through trading.

If the user wants to sell the currency, there are generally two operations:

One is to directly find a buyer and transfer money directly from the wallet to conduct the transaction. In this way, there is no need to go through an exchange, but private transactions may be more risky, and buyers are not easy to find.

The second is to trade through the trading platform. Generally speaking, most people will choose exchange trading, so that they have more opportunities. If you want to trade through an exchange, you must transfer the currencyGo to the trading platform to complete the transaction. Therefore, the exchange becomes a storage place for temporary assets. If the exchange platform fails and cannot be entered into the exchange, the coins there cannot be transferred away, or even if it is entered into the exchange, it may not be transferred due to the failure of the platform itself or other factors.

Therefore, if you want to trade through an exchange, your coins must be stored in the exchange during the transaction. This is equivalent to handing over your coins to the exchange, just like handing over your money. It's the same as putting it in a bank. Although you have an account and password, if the exchange goes bankrupt, you will definitely not be able to get your assets back!

This is also the biggest drawback of centralized exchanges.

The frequent transactions that occur in the currency circle and hackers stealing coins causing user losses are basically caused by this reason!

However, decentralized exchanges are different. The account of a decentralized exchange is your own. When you trade through the exchange, you actually only call the smart contract on the transaction chain, and Assets always remain in your own private account. As long as your password and private key are not lost, your assets are safe.

However, the current development of decentralized exchanges is not good enough and there are relatively few currencies, so most of them still choose centralized exchanges. At this time, you should try to choose a safe and credible exchange with strong strength and better technology.

At the same time, if the amount of personal assets is relatively large, try to transfer it to your own wallet for storage after the transaction is completed, and then transfer it to the exchange when you need to trade.

Therefore, if the exchange goes bankrupt, the coins will not disappear, but you may no longer be able to own these coins.

Virtual currency exchanges, as many people say, are divided into centralized and decentralized exchanges, but most of them on the market are centralized exchanges. You only have a username and password, but in fact All virtual currencies are in the exchange's wallet, and all you see are numbers. If the exchange goes away, the website cannot be opened, which means that all your assets will no longer exist. But one of the most profitable people in the currency circle is those who open exchanges, which are similar to those who open casinos. You have seen a few casino operators run away. As long as you open an exchange, you will not run away. The exchanges have people standing up for them. The reputational damage to Lu was much greater than the actual loss. It is safer to put it on the exchange, but the most appropriate thing is to put your assets in a wallet that you can control. You can control your assets anytime, anywhere.

To put it another way, the currency is still there, but your currency is no longer there.

Looking at the development history of digital currency exchanges, it is the process of exchange collapse. There is a joke in the currency circle that there are more exchanges than coins, and there are many exchanges that have gone missing. Someone has mentioned before that exchanges are divided into centralized exchanges and decentralized exchanges. Let me put it in plain language again.

Currently centralized exchangesIt is mainstream and accepted by the public. This is not an example. Whoever holds the private key owns that part of the digital assets. Then, the essence of recharge in a centralized exchange is that all users’ tokens on the blockchain are recharged to the same digital account on the exchange, and the account private key is in the hands of the founder of the exchange. To begin with, your digital assets no longer belong to you. At the same time, in order to put your mind at ease, the exchange will give you an opening certificate to prove how many coins you have. Just take this certificate and go to the exchange opened by it to trade. Now you understand, the number of coins you see in the exchange app is just a bunch of numbers given to you by the exchange. The numbers in the exchange can be made out of nothing, and you can get as many as you want. The user’s real coins are already in the founder’s private wallet. If the exchange goes bankrupt or the founder dies (this is a real case), then the user’s coins will really be gone.

Decentralized exchanges are still in their infancy. Some of them are embedded in digital wallets, and some have their own account systems + apps. The private key is in the hands of the user. Through smart contracts, user assets are hosted on the chain, transactions are matched on the chain or off-chain, and the results are uploaded to the chain. So, won’t decentralized exchanges fail? no! Decentralized exchanges only solve the problem of digital assets being created out of nothing. For decentralized exchanges with built-in wallets, as long as the order is placed, the assets do not belong to the user at this time. If the exchange happens to run away at this time and the coins are gone, you will have nothing to do with it. A decentralized exchange with a separate account system. Take the EOS chain as an example. The smart contract can be modified. The assets currently hosted on the chain belong to the user, but if the exchange wants to modify the smart contract for evil, yours can also become mine. So how can this work? How can decentralized exchanges do this? Some responsible decentralized exchanges have thought of multi-signing. If the exchange wants to modify the smart contract, it must at least find a few other people who don't want to sign it. The smart contract can only be changed later. To put it simply, I have a password lock here, and four people need to be present to enter the password at the same time to open it. If the exchange goes bankrupt, users can retrieve their coins from the chain through a special smart contract interface. However, this is not absolutely safe. This is only on a single chain. If it involves cross-chain, cross-Ethereum or other public chains, this smart contract will not work. Users can only retrieve assets on the EOS chain, other chains The ones above cannot be found.

Therefore, the coins stored in the decentralized wallet are your assets, and the private key is everything. Small and frequent transactions can be placed on major major exchanges, while large amounts of assets that are not frequently traded can be safely placed in your own wallet.

The existence of virtual currency depends on two conditions. One is the emergence of blockchain technology supported by the Internet, and the other is the existence of a group of rentiers who have nothing to do.

The virtual currency trading platform is just like the real estate agency platform. As long as there is demand for real estate transactions, it does not matter whether there is a trading platform. What is important is that there is this kind of buying and selling relationship.

Real estate transactions are exchanges for money, while virtual currencies (Bitcoin, Litecoin) are traded based on a string of unique numbers. As long as this string of numbers is considered to have a certain value, then the transaction will always exist.

We have changed from an era of "things-money-things" exchange to an era of "money-things-money". The physical exchange function based on survival is far from meeting people's needs for finance, entertainment, leisure and other virtual aspects.

The subject matter has become a medium, whether it is food, clothes, houses, land, companies, brands, software, games, works, stones, stocks, or a signature, a painting, a greeting, Or a string of numbers. In fact, it doesn't matter much, nor is it important.

It is just a medium, a passerby. Never prepared to have it in the first place. Therefore, the emergence of virtual currency is also inevitable in this era.

The world has entered an era of walking on two legs, one leg is for basic survival, and the other is the virtual (including financial and spiritual) world.

Virtual currency will not disappear, it will become even crazier!

This is entirely possible, so it is important to find a reliable platform, but to be honest, it is difficult to ensure security on current platforms.

How to ensure investment safety

Withdraw coins, if you plan to hold them for a long time, you can withdraw the coins after buying them on the platform, so that you are not afraid that the platform will run away, although it is a bit costly.

Find a reliable platform. There are still some relatively large platforms in China. You can refer to them. It is not easy to make recommendations here.

Why is it risky

Bitcoin Trading in the secondary market is somewhat similar to the concept of paper gold. In most cases, there is no physical delivery. If the platform is not even truly linked to Bitcoin and is just a virtual transaction, it will be very troublesome. There is no actual Bitcoin behind your investment.

Due to domestic competition for Bitcoin trading platforms, if trading platforms now want to do business in China, they are just trying to do business on the sidelines, setting up trading platforms overseas, and using some technical means to circumvent supervision. But there are certain risks for investors.

The platform ran away, and the currency must have been taken away by the platform! So the pheasant exchange is risky! It is best to go to the leading exchanges. Although the leading exchanges are generally registered overseas, many overseas ones also have licenses! In addition, just like the leading exchanges are robbing money, no one will give up their qualifications to robbing money!

Statistics show that more than 98% of Bitcoin’s transaction volume is played by Chinese people, and almost all the people trapped in it are Chinese. Let’s sit down and drink and watch a show to see how these people perform., how to save yourself!

㈥ 518 blockchain projects died in 2019

The 518 projects are domestic and foreign, and most of them are foreign currency speculation projects. It is not enough to go bankrupt. Strange, there are but not many such projects in China, and they entered the market too late, all the leeks have been cut, and now that supervision is slowly catching up, hype projects of virtual currency cannot develop. At the same time, blockchain is good for Policies have also kept up, so it is better to follow projects with government guarantees. There is now a SMIC blockchain service platform project initiated by Changsha High-tech Zone. It is a blockchain + public service model and is recruiting companies to join the chain. of. In the future, related corporate affairs and government affairs can be cooperated on the chain. Mainly also has a state-owned background.
