『一』 How blockchain technology opens up an unimaginable new world

The prototype of the concept of blockchain first appeared in the early 1990s. In 1991, several scientists described the first data block application based on cryptographic technology, realizing a distributed file system and preventing file tampering, forgery, and denial through document timestamps. In 1992, improvements were made on this basis, combining multiple document certificates into one block to improve file recording efficiency. With the development of the Internet, in 2008, based on the above examples, Satoshi Nakamoto proposed an electronic currency mechanism that relied on cryptographic technology and calculation methods. This method is also the core of the blockchain. In layman's terms, it means that the other party can be exchanged without knowing the other party. Transactions can be conducted without the need for third-party intervention.

Information contains all contents of value transmission in human society. Since the emergence of human beings, information has been the primary driving force for human development. Several important stages in the development of human society were driven by the information revolution. For example, writing promoted the invention of tools, and the Renaissance promoted the development of capitalism and natural science. These revolutions all reflect the importance of informatization. In today's digital era, blockchain has brought us the fourth industrial revolution. According to its characteristics, it ensures the authenticity and traceability of data, and can be extended to many fields such as the Internet of Things and smart manufacturing. Bringing about the integration of informatization and industrialization.

『二』The future development prospects of blockchain will profoundly affect three aspects

It is still unknown how much technological impact blockchain will bring to the human world, but industry, academia and research generally believe that , currently we have only seen the tip of the iceberg of the potential value of blockchain! Blockchain technology will not only change technology and reshape industries, but will also shake the existing order, traditional rules and value systems of human society. As blockchain technology gradually matures, it is foreseeable that blockchain will show the following development trends.

Zero-knowledge proof

Blockchain is very transparent in nature. Any node running in the blockchain network can view and download all data stored in the ledger. Blockchain combines zero-knowledge proof technology to allow users and businesses to use private data to execute smart contracts without revealing specific data content.

Artificial Intelligence

Blockchain can serve as the foundation for decentralized markets and a coordination platform for various artificial intelligence components, including data, algorithms, and computing power. This could lead to new levels of innovation and use of artificial intelligence. Blockchain will also make such decisions more transparent, explainable and trustworthy. Since all data on the blockchain is public, artificial intelligence will become the basis for providing anti-counterfeiting and privacy protection.

Internet of Things

Blockchain can add a layer of accountability and security to IoT data, becoming the future driver of IoT efficiency, scalability and standardization.The mover. For example, in healthcare, blockchain-enabled IoT devices will allow patients to control access to the data collected by these devices. This technology will make devices more resistant to cyberattacks and provide a detailed record of when another party accessed data. In supply chains, blockchain-based systems, powered by smart contracts, can automate payments based on specific conditions measured by IoT sensors.

The arrival of the blockchain era has revealed the future development trends of various industries, and the increasingly mature technology of blockchain has gradually entered a period of expansion. I believe that in the near future, it will definitely produce greater economic benefits for society.

『三』Blockchain will change the world, how to change it

Blockchain is just a program model. The data formed by this program model is traceable. Compared with Compared with other program models, blockchain programs are more fair, secure and difficult to tamper with. It only plays some role in protecting property rights.
It seems that some expert or scholar said that the value generated by the blockchain will be ten times that of the Internet. I really disagree with this statement. Shanghai is the city with the highest GDP in China and has great development potential. If Some people say that the value created in Shanghai will be ten times that of the whole of China. What do you think?
Blockchain is based on networks and computers, so how can it generate ten times the value of the Internet?

『四』 What technology does Chain Reform mainly use to transform the world?

Chain Reform mainly uses blockchain technology to transform the world.

Chain reform refers to "blockchain reform" or "blockchain transformation", that is, the act of reforming or transforming an enterprise's own business through the application of blockchain technology. As blockchain technology becomes increasingly mature and the importance of the digital economy becomes increasingly prominent, the importance of chain reform is increasingly valued by enterprises.

At present, there is no unified understanding of the content and characteristics of "chain reform". However, it is generally believed that chain reform is not a simple creation of a digital currency, but a comprehensive upgrade of corporate business through blockchain technology, including updating business models, establishing economic models, reshaping the relationship between companies and users, etc., and finally achieving The purpose of optimizing business results.

Chain reform requires enterprises to complete the following tasks:

Establishment of digital asset trading system; digital asset storage The establishment of systems (such as wallets); the design of business models and economic models; the establishment of community construction and operation plans. In terms of characteristics, companies should note that, first of all, chain reform is an organic whole, and the above components should play a role at the same time, not just overcoming technical difficulties.

Secondly, the user threshold should be lowered as much as possible to avoid exposing users to professional terms and technical details related to the blockchain, so as to achieve "non-intuitive chain changes"; finally, in line with the company's own situation and In the case of development trends, chain reform should be carried out as soon as possible. For ordinary enterprises that do not have advantages in technology and resources, flexibility is the best weapon to fight against giants.

『五』The Queen of England is interested in blockchain and how it will change the world

Live and learn, use this sentence to describe the 94-year-old Queen of England who has been waiting for a long time Queen Elizabeth II couldn't be more suitable. Although Queen Elizabeth II is old and frail, she is still paying attention to the most cutting-edge social changes and advanced technological innovation projects, such as blockchain technology that is about to subvert the world. Many people think that blockchain is a scam, but in fact it is not. Many people think that blockchain is a scam based on their understanding of Bitcoin. Bitcoin is actually the most primitive and elementary application of blockchain.

Ethereum is the best embodiment of 2.0 regional chain technology. The key word of this technology is contract. The biggest feature of Ethereum is the achievement of smart contracts. This term was proposed by Nick Szabo in 1995. It uses numbers to define a series of commitments. Once the two parties reach a contract on the regional chain, the contract can be made without third-party certification. It takes effect, breaking the limitations of currency payment in the 1.0 era and greatly increasing the types of transactions. The 3.0 era is an era of comprehensive application of blockchain technology, extending the original simple economic and financial fields to government, society, medicine, agriculture, culture and other fields. The evolution process of regionalized technology applications can be summarized from regionally centralized applications to decentralized autonomous companies and decentralized organizations, and then to regionally centralized autonomous societies.

『Lu』 In the future, blockchain will follow the same journey as the Internet and can truly change the world.

Once upon a time, cryptocurrency was just a money game in people’s eyes. It will generate any value, and some people even hail Bitcoin as the world's largest tulip scam. For example, Chen Sijin is well known to everyone.

More radical people compare Bitcoin to being disgusting and contrary to human civilization. This is Munger’s exact words.

But with the implementation of cryptocurrency applications, facts have spoken louder than words.

For example, we can see the reality: NFT combined with traditional works of art can be auctioned for a sky-high price of 69 million US dollars; DEFI has created a decentralized financial market of more than one trillion; NFT game Axie Infinity The total revenue in a single day has exceeded 40 million US dollars, which is three times more than Honor of Kings. I don’t believe that traditional games are not salivating. There is also web3.0 which is very worth looking forward to.

Every step of cryptocurrency from DeFi-NFT-Metaverse-Game to now web3.0 has impressed traditional capital. So we're seeing some very exciting changes.

I saw a report that after Alibaba, Tencent has also launched NFT, and will sell 300 digital collectible NFTs in the first phase.

Although facing policy restrictions, it may not be possible to trade, but it brings positivity to the marketThe signal, blockchain technology is not air!

Do you still believe this is a complete scam?

Some people say: Using blockchain technology to revolutionize the Internet may be the theme of this bull market.

Decentralization allows the profits of Internet applications to be equally distributed and shared prosperity. I personally believe this with a high probability.

I believe that implementation and application are the ultimate goals of blockchain development. The development of technology can allow the cryptocurrency trading market to get out of the traditional bull-bear cycle, allowing this market to truly bid farewell to the fate of harvesting leeks.

Because the mentality of currency speculation is abandoned, cryptocurrency can be used as a productive capital investment. I think this is the voice of some people in the currency circle, and it also includes many big guys.

If the mentality and goals of market participants have changed because of the greater application of cryptocurrency, there may be a change in the past history.

It is increasingly felt that the blockchain will follow the same journey as the Internet in the future and can truly change the world.

The market has been rising for several consecutive days. We say that there is no market that only rises but never falls. Now market confidence is slowly recovering. Investors will still worry whenever there is any disturbance.

Jiang Zhuoer's article "Do Not Support Deep Bears in the Era of Super Flooding" clearly stated that even if this round is a bear market, it is a short bear market, that is to say, it is not a bear market that lasts for more than a year.

Of course, Jiang Zhuoer’s views come not only from a very detailed analysis of the market, but also from the impact of the general environment and climate, such as the substantial increase in the social acceptance of Bitcoin and the post-COVID-19 era of excessive water release. Investors have decided that there will be no deep bear in 2014/2018, and the remaining script is nothing more than a double-headed bull market in 2013 or a monkey market in 2019. To be honest, although Jiang Zhuoer had no choice but to become an emotional blogger on Weibo, I personally admire his long-term value investment views on cryptocurrency. And most people also report that its success rate in predicting the market is extremely high.

From the data on the chain, both whales and retail investors are buying in large quantities.

Market confidence is also recovering, with the greed index returning to above 0.5.

If the bull market restarts in the second half of the year, every adjustment should be an opportunity for us to buy low.

Even if the worst happens, it will still be a short bear as Jiang Zhuoer said, and there is nothing to be afraid of. Maybe I'm a little optimistic.

Let’s take a look at the trends of Bitcoin and Ethereum

The price of Bitcoin continued to fluctuate downward yesterday, with prices at 415There was pressure around 00 and 40400. Although there were subsequent rebounds, the upward momentum began to weaken. It fell below and moved downward again during the day. It is now close to the lower track of the support area mentioned yesterday. The trend has risen to the 40,000 line and is under pressure. The highs are constantly moving downwards. The early gains are giving up. If the lows are refreshed again in the future, the price will retrace within the day. 38,000 first-line risk.

Looking at the four-hour chart, the Bollinger Bands are open, the price is running in the middle and lower rail areas, the trend remains weak and oscillating, the moving averages are in a downward posture, and the short-term range is constantly moving downwards. If the follow-up The low of 38690 has been refreshed, and the price is expected to test further downwards. I hope you will be prepared in advance. The current trend is fluctuating downward, so when the market does not break through and stabilize at 40,000 during the day, it is recommended that short orders are the main idea, and long orders are supplemented. The upper side suppresses and focuses on the vicinity of 40,000. The rebound allows short orders to be entered nearby, with stop loss at 404,500 and take profit at the 39,300-38,900 area. If it falls below the short-term support of 38690, you can consider short positions and take profit at about 400 points. Consider the 38,000 line for long orders during the day, stop loss at 37,700, and take profit at the 38,500-38,700 area.

Let’s take a look at Ethereum:

Affected by the market yesterday, the upward trend was interrupted, and the price came under pressure to the 2700 line. Although it rebounded many times in the future, No breakthrough has been made. When the trend rebounded to 3660 during the day and came under pressure, the bullish sentiment began to weaken, and the trend retreated into high consolidation. It is expected that the volatile market will continue for a period of time, and the range will focus on the 2500-2700 area.

Looking at the short-cycle hourly chart, the market is under pressure and has pulled back during the day. The current trend is fluctuating around the mid-track. The long and short sides are relatively stalemate. The short-term trend is relatively stalemate, and there is no sign of breaking, so the market is expected to fluctuate. It will continue, we can operate high and low during the day. The upper side suppresses and focuses on the vicinity of 2665, and allows short orders to enter the market. Stop loss is 2700, and take profit is below 2600. The support below will focus on the vicinity of 2560. If there are long orders nearby, consider entering the market. Take profit above 2620.

『淒』Why is it said that blockchain will open a new world

< p>Since the origin of currency, trade between people and countries has become increasingly smooth and convenient. Trade exchanges generate a large amount of transaction information. This information was initially recorded mainly by some specialized systems, such as government systems and banking systems. Therefore, it was often kept confidential and not open to the public. Therefore, when we trade with an unfamiliar counterparty, we need a trustworthy third party or intermediary who has the above information records to help us verify the authenticity of the transaction, such as the government, bank, accountant, and notary. These are called as a "trusted third party".
The emergence of Bitcoin has made “credibleThe status of "reliable third party" is in jeopardy. Bitcoin jointly maintains a ledger that is open to the public through computer networking. These ledgers are completely public and are not controlled by any organization. To be more precise, it is a publicly verifiable, controlled by The digital ledger maintained by the entire distributed network is called "blockchain".
In the blockchain, all transactions are recorded, including the date, time, transaction object and quantity of the transaction, and the network Each node in the blockchain has a complete copy of the big ledger of the blockchain, which is equivalent to each node having a copy of the big ledger. The blockchain uses advanced and complex mathematical principles to allow all users in the system to competitively participate in record keeping. Accounting. In a certain period of time, the user record with the fastest and best accounting will be selected and recorded in the big ledger.
National accounting means that the system does not have a specific independent third-party accountant. The records on any node are lost, and because there is a complete set of replicated ledgers on other nodes, information transmission and transaction completion will not be affected in any way. If someone tries to create a fraudulent transaction, its node information will not be able to reach a consensus with the network, because he The content of the ledger is inconsistent with that of most people, so it will not be recognized by the public unless he can tamper with the ledger records of more than 51% of the nodes. Obviously, this is difficult to achieve because no one can control nodes distributed all over the world at the same time. accounting computer. Therefore, the blockchain will not allow false transactions to be completed.
Through the blockchain, every transaction is public, and thousands of nodes anonymously agree that the transaction occurred The date The essential attributes of 8』 It can increase the price of graphics cards and there is a global power shortage. What exactly is blockchain and why it can change the world

It is very likely that the term blockchain technology that everyone is paying attention to comes from Bitcoin in 2017. skyrocketed to 100,000 yuan a piece, and the stock price of Xunlei Resources, which built Wanke Cloud with blockchain technology, increased 4 times, it can be seen that other things and all companies as long as they are exposed to the word blockchain technology Without exception, they all became an instant hit. The term digital currency gradually became popular among the people, and as it happened, there were usually "coin mining" and "digital currency".

Blockchain The technology is different. You can buy and sell directly with the seller. As long as we pay one hand and deliver the goods, there will be no problem. In this way, the middleman is eliminated, the trading time is greatly shortened, and the whole process is efficient and practical, and it is even absolutely unnecessary. It will happen that the Alipay wallet fails to pay in the early morning of Double Eleven, and the transaction information of the two people can only be known to each other, and the more sensitive transaction information of each other will not be known to a third party, thus ensuring thatProtection of personal information.
