If you are interested, you can go to the official website to inquire and contact us.
⑵ What do blockchains need to have if they want to develop better?
Speaking of blockchain, more and more people are now aware of it, especially In first- and second-tier cities, various blockchain companies have sprung up in endlessly. At present, in the blockchain industry, the most popular project area is anti-counterfeiting traceability, such as DITO, TAC traceability links, etc. So, if the blockchain project wants to develop better, what points do it need to have?
1. The security of the blockchain must be high
If it is safe If there are big sexual problems, then the development of blockchain will be greatly hindered. The absence of security means that the blockchain will not develop. No one wants to use an application or technology that has no security guarantee.
2. The efficiency of blockchain must be fast
Now we are in a fast-paced environment and what we pursue is high efficiency. The project must be able to support large-scale transactions and achieve speeds similar to those of WeChat and Alipay.
3. Blockchain needs to build an ecosystem
Building a community is even more important in blockchain projects. The community is the promoter of blockchain applications. While building a community, it is more critical to find applications.
4. Blockchain needs to be more intelligent
Many things in the future will be intelligent, and if blockchain wants to continue to develop in the future, it will Breakthroughs in intelligence are also needed.
If the current blockchain projects on the market can possess the above four characteristics, then it will be just around the corner for the blockchain technology field to surpass traditional Internet technology. However, the current application of blockchain technology has not yet It’s immature and there is still a long way to go.
⑶ What are the main technical characteristics of blockchain?
“Blockchain is a shared distributed database technology, and its advantages are mainly reflected in distributed decentralization. ization, trustless system and non-tampering and encryption security.”
1. The meaning of blockchain technology
BlockchainChain) technology is a technology that uses a decentralized consensus mechanism to maintain a complete, distributed, and non-tamperable ledger database. It allows participants in the blockchain to implement a trust relationship without establishing a trust relationship. Unified ledger system. Blocks are public ledgers and are maintained at multiple points; chains are stamped with timestamps and cannot be forged. Blockchain is essentially a technology that values security and credibility over efficiency.
There is a database behind all current systems, which is a big ledger. Then who will keep this ledger becomes very important. Now it’s whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger.
Thus, the data becomes very secure. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for all people to participate in accounting, and it will bring about innovation in accounting methods.
⑷ What is blockchain and how to introduce blockchain in a simple and easy-to-understand manner
Blockchain is a term in the field of information technology.
Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "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.
On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". On October 24, 2019, during the 18th collective study session of the Political Bureau of the CPC Central Committee, General Secretary Xi Jinping emphasized that “blockchain should be used as an important breakthrough for independent innovation of core technologies” and “accelerate the development of blockchain technology and industrial innovation.” . "Blockchain" has entered the public eye and become the focus of society.
On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Biwenqiezi".
(4) Introduce the aspects of blockchain and further reading:
Blockchain financial applications:
2016 Since then, major financial giants have also taken note of the trend and launched blockchain innovations one after another.project to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin Group took the lead in pioneering the “blockchain+” standard digital currency.
The standard digital currency is an asset that has been identified, evaluated, confirmed, insured, etc. by a third-party organization and written into the blockchain through rigorous digital algorithms to form a standard correspondence between the asset and the digital currency. relationship, called a standard digital currency.
In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations of people have been striving for, Puyin Group will Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou on the 9th;
At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the relationship between blockchain services and blockchain services will be discussed. The application of social public industries will be discussed. This conference will mark the beginning of the application of blockchain finance and the transformation and development of a new financial ecosystem.

⑸ What is Blockchain
Everyone is talking about Blockchain , when it comes to digital currency, they all turn a blind eye and avoid it in fear
What is blockchain?
What is digital currency?
Let the public be more intuitive and clearly understand that this is blockchain.
What is blockchain? Many people are still not very clear about blockchain. Let’s give you a simple explanation. Let’s take a look.
1. Blockchain concept
Professional terminology: Blockchain is a distributed data storage, point-to-point transmission,
consensus mechanism, encryption algorithm and other new application models of computer technology.
Popular handout: Quoting the explanation in the video, the blockchain replaces all these opaque cups with transparent cups, so that you can always know where your money is, and it will always belong to you. Will be stolen by others.
2. Blockchain
Basic characteristics
1. Decentralization
In traditional centralized network systems In a decentralized blockchain network, hackers can destroy the network by attacking a central node. However, in a decentralized blockchain network, there is no central node to attack
Moreover, the decentralized transaction method is convenient and convenient. There is no third party intervention and direct point-to-point interaction makes large-scale information interaction a reality
It not only ensures that the information is not leaked, but also ensures that the key is in your hand, and you canFast and easy transactions.
2. Openness
The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone and anyone can Query blockchain data and develop related applications through public interfaces, so the entire system information is like a transparent cup, and everyone can see the contents inside.
3. Information cannot be tampered
When a block is verified and added to the blockchain, it will be stored permanently and cannot be changed unless the system is controlled at the same time. More than 51% of the nodes, otherwise the modification of the database on a single node will be invalid, so the data stability and reliability of the blockchain are extremely high.
4. Anonymity
Since the data exchange between nodes in the blockchain follows a fixed and predictable algorithm, the blockchain network does not require trust and can be based on addresses. Non-personally identifiable data is exchanged. The anonymity of the blockchain is a double-edged sword. It not only protects the confidentiality of information and the security of transactions, but it also causes rampant illegal transactions. It has caused difficulties for law enforcement agencies and created a sense of distrust among users.
The above is a partial introduction to the basics of blockchain. I believe that as the public learns more about blockchain, this technology will be recognized and used by more people.
⑹ An introduction to the principles and applications of blockchain technology
1. The blockchain is a series of data blocks generated by using cryptographic methods. Each data block contains the information within the past ten minutes. The information of all Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block. It is the underlying technology of Bitcoin, like a database ledger that records all transaction records.
2. Broad definition: Use encrypted chain structure to verify and store data, use distributed node consensus algorithm to generate and update data, use automated script code (smart contract) to convert and operate data A new decentralized infrastructure and distributed computing paradigm.
3. Narrow definition: A decentralized shared account that combines data blocks into a specific data structure in a chain in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable.
4. Characteristics of blockchain: Decentralization: The processes of verification, accounting, storage, maintenance and transmission of blockchain data are based on distributed system institutions and use pure mathematical methods. It is not a central structure to establish trust relationships between distributed nodes, thereby forming a decentralized and trustworthy distributed system.
5. Time series data: Blockchain uses a chained block structure with timestamps to store data, thereby adding a time dimension to the data and having strong reliability.Verification and traceability.
6. Collective maintenance: The blockchain system uses a specific economic incentive mechanism to ensure that all nodes in the distributed system can participate in the verification process of data blocks, and select specific nodes through a consensus algorithm Add new blocks to the blockchain.
7. Programmable: Blockchain technology provides a flexible script code system to support users in creating advanced smart contracts, currencies or other decentralized applications.
8. Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, and at the same time uses the powerful computing power formed by consensus algorithms such as workload proof of each node in the distributed system to resist external forces. Attack and ensure that blockchain data cannot be tampered with and cannot be forged, so it has high security.
9. Blockchain application scenarios: Digital currency: represented by Bitcoin, it is essentially a digital currency generated by a distributed network system. Its issuance process does not rely on a specific centralized institution.
⑺ If college students want to get in touch with blockchain, where is the best place to start?
If you just want to get in touch, then I suggest you use the following method (mainly for novice students in non-related majors, (Excluding friends who are preparing to work 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 don’t recommend that you start reading the highly professional “White Paper” directly, because the large number of professional terms and nouns 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, blockchain-related knowledge is covered, 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 and distinguish between those you understand and those you don’t understand.
3. In your spare time, you can read the online novel "Blockchain" "Cultivation of Immortality" is probably a story about a leek soul who obtained the blockchain system for cultivating immortality after passing through it, cheating on his life, and started with mining. In thisIn this novel, you will see a lot of nouns (miners, nodes, digital currencies, blockchain systems, etc.). It will be miraculous to bring the knowledge you have learned previously into the book.
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

⑻ 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
After understanding digital currency, you can try to use the trading platform Purchase a small amount of digital currency and 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 walletIf you compare digital currency 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, quotes, celebrity columns, etc.
7. Learn more relevant knowledge
< p> With the above 6 points as a basis, even if we have initially learned about digital currency investment, we still need to learn more knowledge if we want to truly make money by investing in digital currencies. 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. II won’t introduce it. You can find a lot of K-line knowledge online. As we invest longer, understand more currencies, and come into contact with more related matters, we will gradually deepen our understanding of blockchain
⑼ What are the applications of blockchain technology?
Blockchain has become popular, so what are the application fields of blockchain?
At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency.
Financial institutions are the most willing to explore blockchain applications and need new technologies to improve operational efficiency and reduce costs to cope with the current status of the entire global economy. Objectively speaking, the market space in the financial industry is huge, and a little progress can bring huge benefits. The financial industry is an industry with extremely high requirements for security and stability. If the application of blockchain in the financial field is verified, it will have a huge demonstration effect and be quickly promoted in other industries. In the financial field, in addition to digital currency applications, blockchain has gradually begun to be applied in cross-border payments, supply chain finance, insurance, digital bills, asset securitization, bank credit reporting and other fields.
As the application of blockchain technology in the financial field continues to be verified, its technical advantages are gradually showing value in other industries. At present, blockchain application projects are gradually being implemented in fields such as medical and health, IP copyright, education, culture and entertainment, communications, charity, social management, sharing economy, and the Internet of Things, and "blockchain" is becoming a reality.
(1) Blockchain medical care: In the medical field, blockchain can use its anonymity, decentralization and other characteristics to protect patient privacy. Electronic health (EHR), DNA wallet, drug anti-counterfeiting, etc. are all possible application areas of blockchain technology. IBM predicted in last year's report that 56% of medical institutions around the world will invest in blockchain technology by 2020.
(2) Blockchain Internet of Things: The Internet of Things is a very broad concept. If communications, energy management, supply chain management, sharing economy, etc. are included, the Internet of Things with blockchain technology Application will become a very important application field.
(3) Blockchain IP copyright & cultural entertainment: Since the Internet became popular, digital music, digital books, digital videos, digital games, etc. have gradually become mainstream. The rise of the knowledge economy has made intellectual property rights a core element of market competition. However, intellectual property infringement is serious in the current Internet ecosystem, and the copyright protection of digital assets has become a pain point in the industry. Blockchain has the characteristics of disintermediation, consensus mechanism, and non-tampering. Blockchain technology can effectively integrate all aspects of the cultural and entertainment value chain, accelerate circulation, and shorten the value creation cycle; at the same time, the value of digital content can be realized transfer, and ensure that the transfer process is credible, auditable and transparent to effectively prevent theftEdition and other behaviors. Blockchain Public Services & Education: In the fields of public services, education, closed-door charity and public welfare, issues such as file management, identity (qualification) certification, and public trust all exist objectively. The traditional method is to rely on third parties with credibility. The company makes credit endorsements, but problems such as fraud and deficiencies still exist.
