❷ What is blockchain? If you understand these 9 questions, you will understand

What is blockchain? If you understand these 9 questions, you will understand
What is blockchain? What can blockchain do? How to make money with blockchain? I believe that many netizens are confused when faced with this new term. So how can we better understand blockchain and make this new technology available to us? The author has collected nine very common questions from the Internet. I hope that after reading this article, you will have a clearer understanding of blockchain.

Nearly omnipotent blockchain technology
Simply put, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Its core is distributed data, and the result is "decentralization." Blockchain technology can be applied to many scenarios in our lives. Next, let’s take a look at the analysis of blockchain technology!
1. Technology is a double-edged sword. While you are still using your mobile phone to play games, others are already using their mobile phones to make money every month! I want to try Jiaerwu Wuyi Wuba Lingyi Lacquer to make your mobile phone no longer a toy!
Just like nuclear energy is a physical technology, blockchain is an underlying technology at a technical level.
Nuclear energy can be used for atomic bombs and nuclear power generation. Similarly, blockchain can be used for the management of industries and life elements, which may make society more stable, or it may be used by bad guys as the fastest way to commit crimes. .
2. Talking about technical value without the application level is muddying the waters
As the underlying technology, blockchain has its application level.Peace talks. Currently, some people talk about blockchain in terms of business models, some in terms of hardware, and some people talk about blockchain in terms of power distribution. It is gradually becoming clear in the market that blockchain is used in the design of technology combinations and business models, from hardware to software to business model to financial design and many other aspects. But not every blockchain can issue coins, and not every blockchain should issue coins.
3. Technology is decentralized, but the application is not necessarily
Blockchain technology is decentralized, but it can be decentralized or not in upper-layer applications. If it is applied to things, industries and projects that cannot be decentralized, it is not decentralized; if it is used to things where everyone can participate universally and have equal authority, then it can be decentralized.
Including coins on the blockchain, if a country adopts legal digital currency, the coins on the blockchain can also be centralized. The blockchain that supports the operation of Bitcoin is decentralized, but the alliance chain usually has one or more enterprises as the core control alliance, which becomes centralization.
Technology itself and what kind of business and political ecology the technology can support are completely different things.
4. What kind of people use what kind of tools
As a powerful tool, blockchain is powerful not only because of technology, but also because many talented people have invested in it. field, causing the energy of this technology to be amplified. As for whether the power of blockchain benefits society or cuts leeks? It is possible to make the world more turbulent or to make society more harmonious and beautiful.
On the positive side, more kind-hearted people will come in and reach more consensus, and there will be more legislation, restrictions and norms at the national level, which will ultimately allow us to use this technology to give more people opportunities; on the negative side, In other words, it is possible that more greedy and unethical people will come in to divide the wealth, and it is even possible that people in some countries and regions will use this new technology to commit crimes and terrorism.
5. Blockchain promotes the globalization of civilians
Under the blockchain, the global connection space is closer. The 6-degree space will become 5 degrees or even 4 degrees in the future. Blockchain can inspire The growth of various communities. The globalization of interest groups will become inevitable, and there will be various international communities and summits in the future.
6. Blockchain facilitates co-creation
For example, in the past, the connection between international singers and ordinary people had to go through several barriers, including record companies, agents, sales channels, etc. In the blockchain era, international singers publish their songs under blockchain technology. Everyone has the possibility to become a partner of an international singer, write songs for the international singer, or purchase Tokens to obtain dividend rights from distribution proceeds, etc., and enjoy records. Proceeds from distribution and downloads.
7. Trust will become convenient and low-cost
The combined effect of artificial intelligence, big data and blockchain can resolve disputes at the factual level. The tamper-proof nature of the blockchain allows hundreds or even tens of thousands of machines to maintain the same data and encrypt it. Basic facts willtrustworthy. On this basis, the corresponding contracted and authorized information cannot be changed. Replace manual systems with machines, breaking the loopholes in manual operations, the possibility of cheating and even corruption, so that everyone's information can be confirmed to be authentic and trustworthy.
On this basis, if the trust level of the business system is good, trust between people will be enhanced in the process of implementing the designed system.
8． Interaction leads to creativity, and creativity generates income
Blockchain is a comprehensive ledger. Some exchanges are just ideas and creativity at the moment, but they may be the starting point of a certain career or even industry in the future. In the previous accounting system, there may not be value. However, under blockchain technology, values ​​that are not yet seen can be recorded. If this leads to products, creative people can benefit. Various human activities may be valuable, creative, and worthy of recording.
Extended from this, a better application of blockchain can record creative related models, introduction of business opportunities, etc., and put valuable things in an ecosystem. Blockchain can create new ones. A cooperative approach.
9. There will be more legal supporting facilities in the future
The world of blockchain is not a disorderly world. Technology will be used by people, and people are rational.
Records can resolve various factual disputes, and can also cause more issues such as authorization rights, patent and creative copyright management, and many other issues. In the future, there will be more legal supporting equipment, which can not only standardize and manage service consumption and life, but also avoid related risks and problems, avoid and combat crime

❸ Where should college students start if they want to get involved with blockchain? Better

If you just have contact, then I suggest you use the following method (mainly for novice students in non-related majors, excluding friends who are preparing to engage in the blockchain industry)

First of all, if you pay attention to this issue, it means that you have great curiosity or strong interest in blockchain. Then, I do not recommend that you go directly to the highly professional "White Paper". Because there are a lot of professional terms and nouns that can be overwhelming.

In another way, let’s think from the perspective of young people. Before learning blockchain knowledge, we should start with the most basic understanding.

1. On the DouYin platform with huge traffic, if you enter “blockchain” in the search box, many “famous” teachers will appear to explain to you what blockchain is with vivid and short videos. . Although the video content cannot be said to be 100% correct, it is completely sufficient for a simple basic understanding. After all, "There are a thousand Hamlets in the eyes of a thousand viewers. Everyone will have a different understanding and view of the blockchain, and you will also have a different view in the future.

2. You now You may have a little knowledge of blockchain or just have an outline. So, please take your impression and read "100 Questions on Blockchain" (you can search it directly on the Internet). It is still a very short video, but Basically, all knowledge related to blockchain is availableInvolves, including cryptography background knowledge, the history of blockchain, what is blockchain, introduction to Bitcoin and Ethereum, application scenarios of blockchain technology, etc.

Note that you don’t need to study every noun in detail, just browse them all to distinguish between those you understand and those you don’t understand.

3. In your spare time, you can read the online novel "Blockchain Cultivation". It is probably about a leek's soul passing through and obtaining the blockchain system for cultivating immortality. It starts with mining. story. In this novel, you will see a lot of nouns (miners, nodes, digital currencies, blockchain systems, etc.). Bringing the knowledge you have learned previously into the book will work wonders.

Excerpt - "All the heavens and worlds have actually condensed into a huge blockchain... Everyone can do it through the blockchain... All that is needed is virtual currency. We Use your own mana essence...sacrifice to the blockchain...and you will get virtual currency, which can replace currency in reality, buy and sell everything, and even use the blockchain to directly practice, from the blockchain Internet of Things Obtain elixirs and exercises."

Seeing this, do you think it is more interesting than the "White Paper".

4. It is recommended to review "100 Questions on Blockchain" and then read "Bitcoin White Paper".

5. If you are facing an internship, you can go to relevant companies to experience it and apply what you have learned.

6. Of course, following Coin Secretary is also a good choice

❹ Beginner’s Guide to Investing in Digital Currency (Blockchain) , just read this article

Compared with other investment methods, the entry threshold for blockchain and digital currency investment is relatively high. Many friends want to invest in digital currency but don’t know where to start or how to start. Learn something. Although 51Coins has updated a lot of relevant knowledge in the "Beginners Playing Coin" section, it is not systematic enough

This time we will systematically organize the information related to blockchain and digital currency investment. In summary, let everyone understand and invest in digital currency faster and more conveniently

1. Understand the blockchain and digital currency

No matter what you invest in, you must understand it. The same goes for blockchain and digital currencies. There are many introductions about blockchain on the Internet, some are too profound, and some are not comprehensive enough. I personally think the video "100 Questions on Blockchain" produced by Huobi is better

100 videos , all of which are blockchain-related knowledge, including: the birth of Bitcoin, operating principles, blockchain FAQs, mining, wallet introduction, etc., and are all in the form of animated videos, making it easier for everyone to understand. Although the explanation is not detailed enough, it can give you a preliminary understanding of digital currency and blockchain

2. Choose a trading platform

Now you are familiar with digital currencyAfter understanding it, you can try to purchase a small amount of digital currency on the trading platform to experience the process. The purchase and sale of digital currencies must be completed through a trading platform, which is equivalent to a stock exchange in the stock market. It is recommended to choose a large trading platform for the trading platform, which has a comprehensive range of currencies, convenient transactions, and guaranteed fund security

The following three platforms are recommended: Binance, Huobi, and OKEX (ranked in no particular order)

< p> 3. Choose a wallet

If digital currency is compared to cash, a wallet is equivalent to a bank card, used to store digital currency. There are many types of wallets, and the most commonly used ones now are mobile APP wallets (light wallets). Wallets are also divided into types. Different similar digital currencies cannot be transferred to the same wallet. For example, if imtoken is an Ethereum wallet, it can only store Ethereum and tokens issued based on Ethereum, but not other currencies

< p> There are also wallets that claim to support all digital currencies, but most of these wallets are not yet complete.

Of course, after we buy digital currency, we don’t need to deposit it in the wallet, but directly put it in the exchange account, which can save the handling fee and not be so troublesome. Large exchanges such as Huobi and OKEX are relatively It is safe. I personally basically put digital currencies on exchanges

4. Determine the investment plan

Before investing in digital currencies, we must first determine our investment plan and plan to invest. How much money, how much loss you can accept, what is the expected return, and how long the investment time frame is, determine it before investing. Digital currency is a high-risk, high-yield investment product. In the novice stage, you can invest only your spare money that does not affect your life. There is no limit on the amount of investment, and the minimum investment is a few hundred yuan.

Wait until you truly understand the market before making the appropriate investment. Increase the amount of investment, but also remember to control the amount of investment within your own tolerance

5. Select the investment currency

After selecting the trading platform and confirming the investment plan, you can purchase Digital currency, so which one should we buy among so many digital currencies? When buying coins for the first time, it is recommended to choose mainstream coins. You can choose a few coins that you like among the top 20 in the market or recognized value coins

Find out what these coins are for and whether they are available What is the actual value, what news has recently affected the currency price trend, etc.

Understand these issues before buying, and be sure to pay attention to the purchase price before buying

6. Common tools, Website

1. Non-small account: You can view information related to each currency and exchange, including currency price, historical price, increase and decrease, circulation volume, ranking and other information

2 , AICoin: The function is similar to that of non-small accounts. The K-line of aicoin is very convenient and easy to use. It is the first choice for watching K-line charts

3. Coin World: Real-time updates of news and information related to various blockchains and digital currencies

4. Golden Finance: A relatively comprehensive blockchain media platform, including news, news, quotations, celebrity columns, etc.

7. Learn more relevant knowledge

Even if you have the above 6 points as a foundation, you will have initially learned it. Digital currency investment, but if we want to really make money by investing in digital currency, we need to learn more knowledge. The two most important points are to deepen the understanding of the blockchain and technical analysis (K line)

These two are too broad and cannot be learned overnight, so I will not introduce them, K You can find a lot of online knowledge on the blockchain. As we invest longer, understand more currencies, and come into contact with more related matters, we will gradually deepen our understanding

❺ 1 minute to take you to a quick understanding of the area Blockchain technology model structure

Blockchain technology is not a single technology, but the result of the integration and innovation of multiple technologies. Its essence is a weakly centered, self-trusted most The underlying architecture technology.
The blockchain technical model includes the data information layer, the consensus layer of the transmission layer, the incentive layer, the contract layer and the network layer from top to bottom. Each layer has an important role, and different levels cooperate with each other to build a value transfer system that goes to the management center.

The characteristics of the data information layer are that it cannot be forged, fully backed up data, and completely fair (data information, management permissions, coding), and its algorithm design is a blockchain, including blockchain headers and blocks material. The blockchain header consists of three sets of blockchain databases. One set of databases is the parent blockchain hash value, which is used to connect the block to the previous block in the blockchain. The second set of databases is the Merkle root. An algorithm designed to effectively summarize all transactions in the blockchain; the three sets of databases are the difficulty target, time format and Nonce related to the production of the blockchain.

The transport layer encapsulates technologies such as P2P network mechanism, dissemination and authentication mechanism. In the transport layer, new transactions are broadcast to major websites. Each node will include the received transaction information in a blockchain, and each node will try to add it to its own blockchain. Find a proof of workload with sufficient difficulty. When a node finds a proof of workload (qualified to package the blockchain), it broadcasts the program (newly packaged blockchain) to major websites. When And only if all transactions included in the block are valid and have not existed before, other nodes will recognize the validity of the block, and the way to express acceptance is to follow the block. At the end of the block, a new block is created to add to the chain, and any hash of the accepted block is treated as any hash of the new block.

The consensus layer encapsulates various consensus algorithms of nodes, which is the key technology of the blockchain, because this determines the formation of the blockchain, and the accounting decision-making method may affect the entire system. Software safety and stabilityQualitative. At present, more than ten consensus mechanism algorithms have been produced, among which the well-known ones are the proof-of-work mechanism (POW), the easy-to-use Byzantine fault tolerance algorithm (PBFT), the proof-of-interest mechanism (POS), and the equity authorization proof mechanism.

The encouragement layer includes an offering system and an incentive system. Simply put, the incentive system is to encourage nodes to participate in maintaining the optimal operation of the blockchain system in a balanced economic manner, to avoid falsification of the general ledger, and to maintain the driving force for the operation of the blockchain network in the long term.

The contract layer has the characteristics of a programmable controller, which mainly includes smart contracts, consensus algorithms, scripting, and coding. It is the basis for the characteristics of a blockchain programmable controller. Insert the code into the blockchain or dynamic password to implement a customizable smart contract, and under certain specific constraints, it can be executed automatically without going through a third party, which is trustworthy in the blockchain. Basic.
The network layer encapsulates various application fields and examples of blockchain, which is very similar to computer applications and portals on computer browsers. It deploys blockchain core technologies on things such as Ethereum. , EOS and implemented in practice.

❻ The problem of blockchain

Blockchain has certain uses, but it is by no means universal.

There are two main problems with blockchain.

1 The blockchain cannot verify the authenticity of information outside the system. If the information uploaded to the blockchain itself is false, the anti-counterfeiting and anti-tampering of the blockchain will be worthless. To ensure that the uploaded information is authentic, there still needs to be an authoritative agency to check it. Since we all trust the information uploaded by this authoritative organization, why should we be afraid of it tampering with the information? What difference does it make if we use blockchain or not?

2 In the blockchain world, code is the law, and the system can run automatically. However, once it interacts with the real world, the real world may not necessarily agree with the law of the code. For example, if a contract is signed on the blockchain, it will be automatically executed when it expires, and assets will be transferred. However, if there is a bad guy in reality who does not execute the actual asset transfer in accordance with the contract on the blockchain, the contract will be a piece of paper. It is also necessary for the actual courts and other institutions to take action.

The first practical application of blockchain, Bitcoin, has such great influence because it can avoid the above two problems.

Bitcoin is completely self-contained. All information is generated within the Bitcoin system and is closed and verifiable. Bitcoin is not linked to any real assets, so it can be easily passed through The program runs automatically.

Because Bitcoin is completely virtual and runs entirely on programs and rules, it has no borders and is not subject to regulatory control., no need for exchange, free circulation, cannot be frozen or confiscated, available to everyone, and will not be over-issued or devalued. This is its advantage over legal currency.

However, because Bitcoin completely relies on fixed rules and procedures to operate automatically, the supply of Bitcoin is inelastic. If the private key is stolen, the property will be lost and cannot be recovered. This is why it Shortcomings.

Similarly, when using blockchain technology in reality, if we really pursue that code is the law and the private key proves everything, if the private key is stolen, the assets will inevitably be lost and cannot be recovered. For example, if shares are mapped to the blockchain, is it possible that if a major shareholder loses his private key, all his shares will become unusable? This is also an unavoidable problem with blockchain.

In summary, the real killer application of blockchain is actually cryptocurrency. Developing a currency-less blockchain is not that disruptive, and we must be wary of some scammers using the banner of blockchain to defraud money and subsidies.

❼ 108 essential knowledge points for getting started with blockchain

Author: Kong Lin

61. Hold-up

Expect the currency price to rise, but unexpectedly the currency price falls after buying; or expect the currency price to fall, but unexpectedly the currency price drops after selling. But it rose

62. Unwinding

After buying Bitcoin, the currency price fell, causing a temporary book loss, but then the currency price rebounded and the loss turned into profit

63. Going short

After selling Bitcoin because of the bearish market outlook, the price of the currency continued to rise. I was unable to buy in time, so I failed to make a profit

64. Overbought< /p>

The currency price continues to rise to a certain height, the buyer's power is basically exhausted, and the currency price is about to fall

65. Oversold

The currency price continues to fall to a certain low point , the seller's power has basically been exhausted, and the currency price is about to rise

66. Lure bulls

The currency price has been consolidating for a long time, and the possibility of falling is high. Most short sellers have sold Bitcoin, and suddenly The short side raises the price of the currency, inducing the long side to think that the price of the currency will rise and buy one after another. As a result, the short side suppresses the price of the currency and traps the long side.

67. Lure shorts

After the bulls bought Bitcoin, they deliberately suppressed the price of the currency, making the short sellers think that the price of the currency would fall and sell them one after another. As a result, they fell into the trap of the bulls

68 .What is NFT

The full name of NFT is "Non-Fungible Tokens", which is non-fungible tokens. Simply put, it is an indivisible copyright certificate on the blockchain, which mainly serves to confirm the rights of digital assets. , transfer, and numbersThe difference with currency is that it is unique, indivisible, and essentially a unique digital asset.

69. What is the Metaverse

The Metaverse is a collection of virtual time and space, consisting of a series of augmented reality (AR), virtual reality (VR) and the Internet (Internet) Composed of digital currency, which carries the function of value transfer in this world.

70. What is DeFi

DeFi, the full name is Decentralized Finance, which is "decentralized finance" or "distributed finance". "Decentralized finance", as opposed to traditional centralized finance, refers to various financial applications based on open decentralized networks. The goal is to establish a multi-level financial system based on blockchain technology and cryptocurrency. As a basis, re-create and improve the existing financial system

71. Who is Satoshi Nakamoto?

72. Bitcoin is different from Q Coin

Bitcoin is a decentralized digital asset with no issuing entity. Q Coin is an electronic currency issued by Tencent. It is similar to electronic points, but it is not actually a currency. Q Coin requires a centralized issuing institution. Q Coin can only be recognized and used because of the credit endorsement of Tencent. The scope of use is also limited to Tencent's games and services. The value of Q coins is entirely based on people's trust in Tencent.

Bitcoin is not issued through a centralized institution, but it is widely recognized around the world because Bitcoin can self-certify its trust. The issuance and circulation of Bitcoin are jointly accounted for by miners across the entire network, and are not A central authority is also needed to ensure that no one can tamper with the ledger.

73. What is a mining machine?

Taking Bitcoin as an example, a Bitcoin mining machine is a professional equipment that competes for accounting rights by running a large amount of calculations to obtain new Bitcoin rewards. It is generally composed of a mining chip, a heat sink and a fan, and only performs A single calculation program consumes a lot of power. Mining is actually a competition between miners for computing power. Miners with more computing power have a greater probability of mining Bitcoin. As the computing power of the entire network increases, it becomes increasingly difficult to mine bits with traditional equipment (CPU, GPU), and people have developed chips specifically for mining. The chip is the core part of the mining machine. The operation of the chip will generate a large amount of heat. In order to dissipate heat, Bitcoin mining machines are generally equipped with heat sinks and fans. Users download Bitcoin mining software on their computers, use the software to assign tasks to each mining machine, and then start mining. Each currency has a different algorithm and requires different mining machines.

74. What is quantitative trading?

Quantitative trading, sometimes also called automated trading, refers to the use of advanced mathematical models to replace human subjective judgments, which greatly reduces the impact of investor sentiment fluctuations and avoids extreme fanaticism or pessimism in the market.Make irrational investment decisions under certain circumstances. There are many types of quantitative trading, including cross-platform trading, trend trading, hedging, etc. Cross-platform trading means that when the price difference between different target platforms reaches a certain amount, sell on the platform with a higher price and buy on the platform with a lower price.

75. Blockchain asset over-the-counter trading

Over-the-counter trading is also called OTC trading. Users need to find their own counterparties and do not need to match the transaction. The transaction price is determined by negotiation between the two parties. The two parties can fully communicate through face-to-face negotiation or telephone communication.

76. What is a timestamp?

The blockchain ensures that each block is connected sequentially through timestamps. Timestamps enable every piece of data on the blockchain to have a time stamp. Simply put, timestamps prove when something happened on the blockchain and cannot be tampered with by anyone.

77. What is a blockchain fork?

Upgrading software in a centralized system is very simple, just click "Upgrade" in the app store. However, in decentralized systems such as blockchain, "upgrading" is not that simple, and a disagreement may even cause a blockchain fork. Simply put, a fork refers to a disagreement when the blockchain is "upgraded", resulting in a fork in the blockchain. Because there is no centralized organization, every code upgrade of digital assets such as Bitcoin needs to be unanimously recognized by the Bitcoin community. If the Bitcoin community cannot reach an agreement, the blockchain is likely to form a fork.

78. Soft fork and hard fork

Hard fork means that when the Bitcoin code changes, the old nodes refuse to accept the blocks created by the new nodes. Blocks that do not comply with the original rules will be ignored, and miners will follow the original rules and create new blocks after the last block they verified. A soft fork means that old nodes are not aware of the changes to the Bitcoin code and continue to accept blocks created by new nodes. Miners may work on blocks they have no understanding of, or validation of. Both soft forks and hard forks are "backwards compatible" to ensure that new nodes can verify the blockchain from scratch. Backward compatibility means that new software accepts data or code generated by old software. For example, Windows 10 can run Windows XP applications. Soft forks can also be "forward compatible".

79. Classification and application of blockchain projects

Judging from the current mainstream blockchain projects, blockchain projects mainly fall into four categories: Category 1: Currency; The second category: platform category; the third category: application category; the fourth category: asset tokenization.

80. USDT against the US dollar

USDT is Tether USD, a token launched by Tether that is against the US dollar (USD). 1USDT=1 US dollar, users can use USDT and USD for 1:1 exchange at any time. Tether company executiveA 1:1 reserve guarantee system is implemented, that is, each USDT token will have a reserve guarantee of 1 US dollar, which supports the stability of USDT price. The unit price of a certain digital asset is USDT, which is equivalent to its unit price in US dollars (USD).

81. Altcoins and alternative coins

Altcoins refer to blockchain assets that use the Bitcoin code as a template and make some modifications to its underlying technology blockchain, among which Those with technological innovations or improvements are also called alternative coins. Because the Bitcoin code is open source, the cost of plagiarism in Bitcoin is very low. You can even generate a brand new blockchain by simply copying the Bitcoin code and modifying some parameters.

82. Three major exchanges

Binance

Okex

Huobi

83. Market software

Mytoken

Non-small account

CMC

84. Information website

Babbitt

Golden Finance

Coin World News

85. Blockchain Browser

90. Platform currency

The digital currency issued by the platform is used to deduct handling fees, transactions, etc.

91. Bull market, bear market

Bull market: rising market

Bear market: falling market< /p>

92. Blockchain 1.0

A currency trading system based on distributed ledgers, represented by Bitcoin

93. Blockchain 2.0

< p> The contract blockchain technology represented by Ethereum (smart contract) is 2.0

94. Blockchain 3.0

In the era of intelligent Internet of Things, it goes beyond the financial field and provides various The industry provides decentralized solutions

95. Smart contracts

Smart Contract is a computer protocol designed to disseminate, verify or execute contracts in an information-based manner. Simply put, an electronic contract is set in advance and once both parties confirm, the contract is automatically executed.

96. What is a token?

The token economy is an economic system with Token as the only reference standard, which is equivalent to a pass. If you own Token, you have rights and interests, and you have the right to speak.

Big data is the means of production, AI is the new productivity, and blockchain is the new production relationship. Big data refers to a collection of data that cannot be captured, managed and processed within a certain time range using conventional software tools. It is a massive, high-growth and high-volume data set that requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities. Diverse information assets. Simply understood, big data is massive data accumulated over a long period of time and cannot be obtained in the short term. Blockchain can be used as a way to obtain big data, but it cannot replace big data. Big data is only used as a medium running in the blockchain and has no absolute technical performance, so the two cannot be confused. (The simple understanding of production relations is the labor exchange and consumption relations, the core lies in productivity, and the core of productivity lies in production tools)

ICO, Initial Coin Offering, initial public token issuance, is the first step in the blockchain digital currency industry. Crowdfunding. It is the most popular topic and investment trend in 2017, and the country launched a regulatory plan on September 4. Speaking of ICO, people will think of IPO, and the two are fundamentally different.

99. Five characteristics of digital currency

The first characteristic: decentralization

The second characteristic: having open source code

The third feature: independent electronic wallet

The fourth feature: constant issuance

The fifth feature: global circulation

100. What is decentralization?

It has no issuer, does not belong to any institution or country, and is a publicly issued currency designed, developed and stored on the Internet by Internet network experts.

100. What is measurement (scarcity)?

Once the total amount of issuance is set, it is permanently fixed, cannot be changed, cannot be over-issued at will, and is subject to global Internet supervision. Because the difficulty of mining and mining changes over time, the longer the time, the greater the difficulty of mining, and the fewer coins are mined, so it is scarce.

101. What is open source code?

The alphanumeric code is stored on the Internet. Anyone can find out the source code of its design, everyone can participate, can mine it, and it is open to the world.

❽ Blockchain 100 - Zhou Kaiyu: Can blockchain credit innovation break industry credit barriers

Mr. Zhou Kaiyu, CEO of Zhenxing Technology

Currently, credit reporting has become a key part of the credit system and forms an important support in the operation of the modern financial system. There are certain difficulties and pain points in traditional credit reporting, but the decentralized and non-tamperable characteristics of blockchain will change in one fell swoop the issues of insufficient data privacy protection involved in the credit reporting process and consensus trust issues in the data sharing transaction process.

Mr. Zhou Kaiyu elaborated on the advantages of the combination of blockchain and credit reporting, and described the development status of the blockchain credit reporting industry at the legal level. At the same time, he expressed his views on the future development of Zhenxing Technology and the future direction of blockchain innovation.

Zhenxing Technology is positioned as a blockchain value ecological enterprise and is committed to building the next generation of trusted application service basic network based on blockchain. In June 2017, the company established a stable team structure and carried out related technical matters. From July to August, the first version of Zhenxing’s technical white paper was completed. Currently, Zhenxing has implemented the first version of the system and has also started providing related services in terms of identity verification based on the blockchain.. In the later stage, further development based on the second version of the credit evaluation system will be carried out.

In terms of ecological construction in the future, Mr. Zhou Kaiyu said that the blockchain credit industry has both value and opportunity. He hopes that industry partners with some high-quality resources on the B-side in the early stage can jointly expand services and eventually achieve A large number of users gather on the C-side, creating an ecological environment for high-credit preference transaction customers. In terms of the company's development plan, Zhenxing will break the inherent thinking of traditional blockchain anonymous verification, build a decentralized strong identity verification basic network, and integrate a trusted Internet service ecosystem.

The original intention of choosing a project that combines credit reporting with blockchain

“Choose blockchain to develop because it has a community-based approach that maintains the stability of the entire system. Consensus reward, consensus reward is a process of social value redistribution. In the process of social value redistribution, a value effect is formed in which the wool comes out of the pig and is paid by a third party. While achieving credit value, it can It is a means to encourage everyone to maintain high credit." Mr. Zhou Kaiyu said.

According to Mr. Zhou Kaiyu, in the traditional credit reporting process, data is processed in a traditional centralized way. The data exists on a centralized platform, but it is difficult to verify the security of user data. The issue of personal privacy data has attracted attention from society, government, enterprises and other levels. Blockchain will form a combination with blockchain through the credit alliance.

At the same time, the Block Hall Chain can combine some personal security mechanisms to achieve comprehensive and strict protection of personal privacy data and complete credit reporting services with authorized attributes. Zhenxing’s credit reporting service combines the advantages of blockchain, using personal data and individuals themselves to provide diversified credit reporting services through data services.

What are the advantages of the combination of blockchain and credit reporting?

When it comes to the combination of blockchain and credit reporting, its main core lies in the data level, since credit reporting uses a large amount of user data. In a decentralized system like blockchain, data needs to be maintained jointly by everyone. It is difficult for anyone to change the data. This can clearly ensure the security of user data. Any access to data requires user authorization. occur.

Regarding the current legal status of blockchain credit reporting, Mr. Zhou Kaiyu introduced, “In terms of credit reporting, the country has many management regulations to regulate the processing of customer data by enterprises. Blockchain + reporting In terms of information, it is a very good technical method." In his view, “Blockchain + credit reporting has become the only basic technology that can fully meet all requirements in terms of privacy protection when most technologies cannot meet the needs of credit reporting.”
< br />What are the options for future blockchain innovation directions?

Mr. Zhou Kaiyu said that the blockchainDevelopment is still at an early stage, and there is huge room for future innovation in blockchain. Currently, we are optimistic about the direction of innovation, such as asset digitization. Asset digitization will be a relatively long process, and various applications will continue to emerge during development. In terms of technological innovation, blockchain still has a lot of room, and more attempts are being made in new directions of upgrading and balancing.

Zhenxing hopes to build a value exchange ecology with high performance value, and hopes that under its nourishment, everyone will be happy to maintain their personal credit, and everyone will be able to participate in the credit transaction process. gain from it. The future development of Wuxiaokai will be based on the core concept of maintaining high credibility and combating dishonest people.
