❶ What is the underlying logic of NFT?

The reason why NFT has not left the industry is because the public still has doubts about its value. NFT can be simply and roughly understood as a digital certificate based on the blockchain, which can digitize physical or virtual items, or directly create digital creations. Therefore, everything can be NFT-based, and everyone can create NFTs.

Actually, not so. The reason is simple. There are no two identical leaves in the world. The problem is that most leaves have no collection or trading value. Even NFT is futile. After all, creating or purchasing NFT requires paying gas fees. If the unit price is too low, the cost cannot be covered.

A blockchain developer told Zinc Scale: “This is just like an ordinary QQ account, where everyone lacks interest, but QQ beautiful accounts are different, and the selling price of QQ beautiful accounts is different. Different, but flocking together." In other words, the underlying logic of NFT is scarcity, or creating an atmosphere of scarcity.

For example, the apes of Bored Ape Yacht Club are holding high the banner of artistic creation. It doesn’t matter whether it looks good or not, and it doesn’t matter whether you can appreciate it. What matters is There’s room for storytelling. "Actually, many people are speculating on NFT as 'baseball cards'." Yu Wenqi explained, "How much did it cost to print 'baseball cards' back then? Why are they so valuable now?"

The so-called "baseball cards" are cards printed with different baseball stars, similar to a special U.S. stamp. Scarce cards can even be auctioned for millions of dollars, making them highly collectible. . NFT is a very new asset carrying method based on blockchain technology that allows digital assets to be passed down permanently. It not only has collection value, but also has room for future appreciation.

In other words, NFT emphasizes investment attributes, while traditional virtual currencies emphasize payment attributes. According to the "2020 Global NFT Industry Ecological Reference" jointly released by ChainDD and KuCoin, the use scenarios of NFT include game props, collectibles, virtual worlds, encrypted artworks, tickets, asset mapping, coupons, etc. The current main applications are currently Focus on games, virtual worlds, and crypto art collectibles. It should be noted that the investment logic of NFT is still questionable.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "blockchain technology" approved by the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" carried out by the School Planning and Construction Development Center of the Ministry of Education of China. Professional” pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

❷ Is the Metaverse a technological outlet or a capital game?

“You can’t make money from something you don’t understand.” Just ask yourself one sentence, youDo you know its operating mechanism and business model? Knowing is the outlet for the wind, but not knowing is the trap that will harvest you. It's not easy to code, I hope you can adopt it.

❸ Blockchain can be defined

On March 12, 2018, the Hangzhou Municipal Science and Technology Commission, Hangzhou Financial Work Office, Xiaoshan District People’s Government, and The second All Things Growth Conference co-sponsored by Hangzhou Daily Newspaper Group and hosted by Hangzhou Venture Capital Association and Hangzhou Bank was held in the press conference hall of Hangzhou International Expo Center. Babbitt and Bytom founder Chang Chai gave a speech on "The Future Can Be Predicted, Blockchain Can Be Defined" keynote speech.
The following is the content of the speech:
Good morning everyone, I am very happy to be invited to do such a sharing. The theme I shared is "The future can be predicted and blockchain can be defined."
I used to be a science fiction writer and wrote some science fiction novels in college. At that time, science fiction was still a very niche group and very few people read science fiction novels. Later, I had a post that is now very popular. In 2011, a college student asked on Zhihu: If you have 6,000 yuan for investment and financial management, what advice do you have? The advice I gave him at that time was to buy Bitcoin. . Now it seems that this is a piece of advice worth 20 million. Of course, it is a sad story because the subject did not buy Bitcoin in the end. It is also a sad story for me, because many people in the novel I wrote I haven’t read it, but this advice is often mentioned. In recent years, people have been sending me private messages asking me which coins to buy. However, I am not an expert in investment and financial management. Our company is engaged in blockchain.
Babit established the website in 2011 and established the company in 2014, so we may be the first batch of blockchain companies in China. On what basis do we judge that blockchain technology may be popularized or survive in the future?
This would like to mention a science fiction novel I once wrote in college called "The Art of Slaying Dragons". This computer-themed novel was written in 2007. It tells the story of hackers who can use huge amounts of computing resources on the Internet in the cloud era to complete some very grand scientific computing projects. After this novel was published at the time, it was criticized by many readers. They think this novel seems unreal and doubt that hackers' abilities are beyond ordinary people's imagination.
But now it seems that this novel is not an exaggeration at all. Why? Because in the cloud era, the abilities between people will be disproportionately amplified. In reality, the abilities between people may be a kind of The normal distribution is just like a person's height and weight, but on the Internet, people's ability and influence will be disproportionately amplified. It is a combination of the Matthew effect + the long tail effect.
The core ideas of this novel are two points. The first point is that cloud computing will amplify people's abilities, and the improvement of computing power will amplify people's abilities. The second point is that computing is power. So when a new thing like Bitcoin comes out, it seems that the world written in my novel is becoming a reality. When 2008 to 2When Bitcoin was introduced to China in 2010, many people had already heard of Bitcoin, but did not pay attention to it. In fact, to understand a thing like blockchain, you need some background knowledge.
In addition, I would like to introduce a book, which is "Out of Control" written by Kevin Kelly. This book was written in the 1990s, but this book is very forward-looking and has a chapter that introduces the development of cryptocurrency. Pioneers, but these pioneers later became martyrs, what was the reason for their failure? In fact, blockchain needs to be based on three core technologies, and these three technologies are gradually maturing. The first technology is asymmetric encryption. In 1985, elliptic curve function encryption was already very mature, but unfortunately it was implemented in a centralized way. What are the risks of centralization? That is, when issuance If the currency company collapses or the founder is arrested, or the central server is attacked, it will cause the system to collapse, so it failed later. In 2000, someone began to introduce peer-to-peer technology into cryptocurrency for the first time, taking the lead in realizing distributed cryptocurrency. However, it also failed later. The reason is very simple, that is, there is no way to find a way to solve double payment (the same money is used). twice). It was not until 1997 that Adam Baker proposed proof of work. In 2004, Halfini expanded this technology into a reusable proof of work, so the 2008 Bitcoin white paper was successfully published.
And the carefully designed technical solutions in Bitcoin later seemed to be very advanced. For example, in 2014, Snowden revealed that elliptic curve function encryption is unsafe because the US National Security Agency has set up a backdoor in this encryption standard, giving the NSA an unknown method to weaken this curve. , at that time many people exclaimed that Bitcoin was dead and that the system might collapse, but later Satoshi Nakamoto did not use the encryption standard promulgated by the National Security Agency, but used a very rare curve.
To give another example, after hashing twice, a quantum computer cannot threaten the Bitcoin address and cannot decipher the Bitcoin private key from the address. What’s more interesting is that Satoshi Nakamoto also adopted a weird transaction method called a change mechanism. The change mechanism is that the remaining balance of each transaction is transferred to a new address. Now it seems that this is actually for the purpose of Prevent quantum computers, because the public key of a Bitcoin transaction will only be exposed on the blockchain during the transaction. You only need to transfer the remaining money to a new address during each transaction. In fact, you The public key will not be exposed on the blockchain.
So judging from so many details, it can be said that Satoshi Nakamoto is a bit like a person who is extremely careful, so many people think that he is not a person, but an organization.
I just mentioned why the proof-of-work mechanism was introduced to the blockchain and Bitcoin, and this cryptocurrency was successful? Because the proof-of-work mechanism is actually hash calculation. Why is calculation so important to the blockchain? ?I can give a very easy-to-understand proof through such a table.
ThisThis table shows that the real world and the digital world are actually in a mirror relationship. The real world can also be called the atomic world. In the real world, things are randomly distributed and random. In the digital world, most things are pseudo-random. , There are no two identical leaves in the real world. Everything on the Internet can be copied. In the real world, it is a normal distribution. In the digital world, it is a power law distribution, which is the Matthew effect + long tail effect. In the real world, things are competitive resources, which are exclusive resources. For example, if I own a microphone or a glass of water, others cannot own it. All resources in the digital world are non-competitive resources. For example, I transfer a document and article to another person, but in fact this document cannot be transferred like a book in reality, because this document may be saved infinitely in my computer or other storage media. A copy, so based on such a mirror relationship, we can ask the question, why is it so difficult to copy exactly the same thing in the real world? This question can be turned into whether you can create a perfect crystal in reality, you can create A perfect crystal can actually copy exactly the same thing, but the third law of thermodynamics tells us that if you want to create a perfect crystal, you need absolute zero, and you have to invest a huge amount of energy. In turn, through this symmetrical thinking, we can This raises the question that in the digital world, that is, on the Internet, it is very difficult to prevent something from being copied and to achieve such competitive resources. To achieve such a competitive resource, a huge amount of personnel consumption is required, which is computing. The more computing power invested, the higher the barrier against double spending, which is why computing matters.
So since the real world and the digital world have such a mirroring relationship, the blockchain can actually be understood as the reverse machine of the printing press. I like to use such a very vivid metaphor to define the blockchain as the printing press. Reverse process.
Why is the printing press so great? In fact, before the birth of the printing press, human knowledge and information were competitive resources. Whether it was the Bible or martial arts secrets, they were all competitive resources. But after the birth of the printing press, this knowledge and Information has become a non-competitive resource that can be copied on a large scale, or the marginal cost of copying is almost equal to 0, so there is the subsequent information revolution. With the Internet, the Internet is actually an enhanced version of the printing press. But the problem with the Internet is that it is difficult to transfer competitive resources in the digital world. This is also the reason why some cryptocurrency pioneers failed in the 1990s. Blockchain solves this problem. It is the first to realize competitive resources on the Internet. The first competitive resource is of course Bitcoin, which is the first domino to be erected. After the first card falls, we can imagine that the second and third cards will fall as long as they have value attributes. They are all very suitable for using blockchain for registration and circulation, because the Internet is suitable for things with information attributes, so we say that the Internet is an information transmission protocol, and blockchain isValue transfer protocol, any resource with value attributes is actually very suitable to be combined with the blockchain.
So I don’t think the blockchain will replace the Internet. The blockchain itself is a parallel world of the Internet. It is to do some things that the Internet cannot do, so it may propose many business models. In my opinion, it is not It is unrealistic. For example, it combines things with information attributes and business scenarios with blockchain. In fact, I think it is not that appropriate, because scenarios with information attributes are suitable for the Internet, and only scenarios with value attributes are suitable for "blockchain." +".
Let’s further deepen the mirroring relationship between the Internet and blockchain. The carrier of the Internet is often software, and the carrier of blockchain is generally protocols. Software needs to apply for patents to establish its own patent barriers. On the contrary, with blockchain, most blockchain projects are open source, and you are very welcome to copy it. The code does not need to establish such patent barriers or moats. The main body of software development is usually a company, and the main body of blockchain development is often a community or foundation, which is a very loose organizational form. Software requires constant iterative upgrades, but iterative upgrades of protocols are very difficult, so they are generally very stable, because protocol upgrades require the approval of the entire network consensus, which is of course very, very difficult. That’s why there are so many Bitcoins. The software can be maintained and updated, and the protocol is that it cannot be shut down after it is started, and it runs 24 hours a day. Based on this kind of thinking, we can solve many doubts in our hearts. For example, in 10 years ago, many experts or big names in the investment community believed that although Bitcoin was a pioneer, it did not necessarily have the last laugh. How to prevent being defeated by latecomers? This is a typical Internet thinking. Internet thinking regards Bitcoin as a software. Through technological upgrades, latecomers may catch up, just like the browsers in the 1990s. Later, the early browsers were defeated by the newcomers. But in fact, Bitcoin cannot be regarded as a kind of software, but a protocol. The method of implementing this kind of blockchain is already a minimum feasible solution, and there is not much room for optimization.
Many people understand blockchain as the fifth paradigm revolution, because it is based on the summary of technological updates in the past few decades, which means that such a paradigm revolution, a leap-forward revolution, will be completed approximately every two years. The 1970s were mainframes, the 1980s were PCs, the 1990s were the Internet, the 2000s were the mobile Internet, and the blockchain was born in the 10s. The trend behind this is actually a trend of decentralization. Mainframes are used in scientific research institutes or military institutions. PCs have entered families. The Internet has entered tens of millions of people. Mobile Internet has pervaded the world. In all aspects of life, blockchain has become more decentralized, and there is no longer even a central server. There is another detail here, that is, the time of the blockchain was calculated from January 1, 1970. Why does it have such a feature? In fact, it is because many programming languages ​​are derived from Linux systems, and Linux is derived from mainframes. , so it has the imprint of such an era invisibly.
In fact, there is a deeper evolutionary law behind it, such as the three stages of asset evolution. The evolution of assets can be divided into three stages. The first stage is the confirmation of asset rights, which is the equityization of assets. After the rights of assets are confirmed, It can be transferred as a whole, so it is a bit like the solid stage of the asset. The second stage is asset securitization. After securitization, the assets can be divided and transferred, and their liquidity is obviously stronger. It is a bit like the liquid stage of assets. The liquid stage also has its limitations. For example, the business requires a container. , this container is the platform for assets, and assets still cannot flow across platforms. Only after the assets are blockchainized, that is, after the assets are put on the chain, will they truly enter a gas phase, because everyone can manage assets through their own private keys, whether it is Equity, income rights, debts, intellectual property rights, etc., as long as they are assets with this value attribute, they are suitable for registration and circulation using the blockchain, so they are no longer limited by the platform, because everyone can complete it through their own wallet. The process of asset transfer does not require a centralized authority or a centralized trading place. More broadly, many people have summarized the stages of blockchain evolution. The first stage was in 2009 with Bitcoin as the Representing the stage of cryptocurrency to solve value transfer matters, it can be understood as the 1.0 of blockchain. In 2017, the era of issuing virtual assets through smart contracts emerged, represented by Ethereum, which can be understood as the 2.0 of blockchain. We believe that we will enter the third stage in 2020, using smart contracts to issue physical assets or help real assets to be put on the chain. The blockchain will eventually move away from the virtual to the real and serve the real economy. So Babbitt is doing the third stage, which is our prediction of the future development trend of the blockchain.

❹ What is blockchain

What is blockchain? What changes will it bring to your future life?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

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 cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In fact, the original English version of the Bitcoin white paper does not appear in the word blockchain, but uses chain of blocks. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The State Internet Information Office issued the "Blockchain Information Service Management Regulations" on January 10, 2019.》, effective from February 15, 2019.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.

So in conclusion, this is undoubtedly a new technology that changes life. In the future, the production activities of the entire society will be carried out with blockchain as the underlying logic. Many things We all have it at our fingertips, and with the integration of artificial intelligence and big data, we can easily handle things that may seem cumbersome now, such as some securities market transactions and intelligent matching of financial management activities.

To put it simply, blockchain is a network computing center that integrates people, property, machines, and goods, and packages them into a whole; putting it on an infrastructure to run.

❺ Huobi mining pool is not easy to mine

Hello, Huobi is certainly not easy to mine. Huobi is also something that belongs to the blockchain. Blockchain is a term in the field of information technology. Essentially, it is a shared database. The data or information stored therein has the characteristics of "unforgeable", "full traceability", "traceable", "open and transparent", and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
Extended information:
1. When investing in blockchain, you should pay attention to the following matters. When a creative team invests in a blockchain project, it must first look at the project's main creative team, especially the core members. If the stronger team is first-class in technology and marketing, then they will be more aboveboard in team promotion. If the founding team of a project cannot share their ideas and progress on social media such as QQ groups, WeChat, and forums, then we will question whether their team takes the matter seriously. Therefore, we will be relatively cautious in investing, because all blockchain projects must have active and open discussions on social media and answer investors' questions in order to gain trust.
2. Project introduction, first of all, we need to read the white paper of the blockchain project to see if they have done it in detail and clearly explained the project and the problems that can be solved. Even if there are too many English and technical terms that you don’t understand, you must read it carefully at least 3 times and try to understand it as much as possible. From a model perspective, it is innovative. Any unrealistic bragging? Of course, there is no need to consider unrealistic projects; technically, there are core technologies or functions that are irreplaceable. For example, Ethereum has a better technical solution than Bitcoin in the short term - smart contracts. If you don’t understand technology, you should consider its rationality and feasibility from a model perspective, whether it really matches the blockchain, and whether it can be implemented, because too many projects just borrow the name of the blockchain.
3. Financing history, there are many excellent blockchain start-up projects that have been operating for a year and a half, and even received oneinvestments from some investors or institutions. Such projects are generally more reliable. However, we should be cautious when investigating this. It is best to find more knowledgeable people in the industry to ask about their financing status, mainly to confirm the authenticity. If we find that these are all fake, we can basically not consider investing in this project.
4. Specific and feasible plans must be studied. This is key to project development and whether your return on investment can be realized. If a project does not have a clear development plan, let alone profitability, it will be difficult to survive. We could just abandon such a project.

❻ Is the UNION platform a legal platform? What does this platform do?

It is legal. Union's decentralized platform is committed to creating multiple matrices such as mining ecology, asset trading ecology, entertainment ecology, contract ecology, non-functional ecology, and DEFI ecology. The platform currently has more than 50,000 real users and will serve more than 1 million users in the future. The United Decentralized Chain Platform has reached strategic cooperation with well-known institutions such as the original Boduo Wallet Market Team, Oaktree Capital, Shengbotong Fund, MNS Capital, Tiandao Capital, and Singapore GT Group to jointly participate in the election of 100 master nodes. At present, more than 40 master nodes have entered the computing power verification stage, jointly assisting the ecological implementation of the project and accelerating market deployment.

As a platform, Union not only provides users with a variety of asset trading scenarios, but also provides merchants with asset management, transaction matching, risk control, and marketing through blockchain technology. and other one-stop services to maximize platform value and business value. We won’t be like now, feeling like we have nothing because we don’t have the Internet. Blockchain is decentralized, which gives us enough time to think, change, try, and improve the infrastructure of our world.

❼ What is a Bitcoin node?

So let’s talk about what a node is?
A node is a network node in the blockchain distributed ledger system, connecting to the server through the network , computers and other equipment, blockchains of different natures have different ways of becoming nodes. For example, Bitcoin participates in transactions and mining, and EOS participates in the election to become a node.
The following is what a Bitcoin full node is.
Bitcoin full node is a node that downloads and preserves complete blockchain data by loading the Bitcoin client (including BitcoinUnlimited version and bitcoincore version, etc.).
Because of the congestion of the blockchain transaction network, the author solves the problem by adjusting broadcast communication, information encryption and decryption, consensus mechanism, and transaction verification mechanism. In the entire Bitcoin network, from miners to ordinary users, it can be seen as It is a node in the Bitcoin network, but because Bitcoin has the characteristics of decentralization, its important role in the entire network is the "Bitcoin full node."
