① The significance of the establishment of the Blockchain Alliance

The 2018 Global Media Blockchain Summit was held at the Financial Hall of the Hong Kong Exchange on the 19th. Many media attending the meeting focused on blockchain Development prospects, industry trends and other issues, they made suggestions on deepening media blockchain cooperation and promoting the healthy development of the industry, and jointly announced the establishment of the Global Media Blockchain Alliance.

According to reports, the alliance will provide an open access mechanism for media members, integrate resources, and create a trustworthy media blockchain platform. At the meeting, the Global Media Blockchain Alliance released the "Hong Kong Initiative", advocating that media disseminate advanced concepts, encourage ecological innovation, and continuously provide high-grade, high-quality information and services in the dissemination of information in the blockchain field.

Yu Guoming, executive dean of the School of Journalism and Communication at Beijing Normal University, pointed out at the summit that only through full development of media blockchain can a more sound and good media ecosystem be formed. Mainstream media must consciously assume social responsibilities in the development of media blockchain and become organizers and builders to promote technological progress and business innovation.

Ding Laibin, secretary-general of the Global Media Blockchain Alliance, said that blockchain technology is expected to bring new changes to society and its healthy development needs to be protected. In terms of public opinion supervision in the blockchain field, the media should give full play to its role in exploring the value of the industry, combating industry fraud, and contributing to the development of the blockchain industry.

② Comic popular science about blockchain, you need to know the basic concepts

No matter what industry you are in, you must have learned about it in these two days You can see various news about blockchain in your circle of friends. So, what exactly is such a popular blockchain?
1. What exactly is blockchain?
A cartoon will let you understand in seconds
Blockchain technology refers to a kind of public participation in recording method of accounting. There is a database behind all systems. You can think of the database as a big ledger. Currently, each is keeping its own account.
Since there is no centralized intermediary agency, letting everything run automatically through preset programs can not only greatly reduce costs, but also improve efficiency. And since everyone has the same ledger, it can ensure that the ledger recording process is open and transparent.
Blockchain technology is the underlying technology of Bitcoin. Without the operation and management of any centralized organization, Bitcoin has been running very stably for many years without any problems, so some people have noticed its underlying technology. , extract the abstraction of Bitcoin technology and call it blockchain technology, or distributed ledger technology.
According to a report released by Santander, Spain's largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.
Cloud computing is usually defined as the provision of dynamically scalable and often virtualized resources over the Internet, but providesCloud computing platforms are often centralized organizations. The network composed of blockchain generally does not have a specific organization, so blockchain is closer to the definition of a distributed computing system and is a type of distributed computing.
Q Coin is a centralized electronic currency, including the total amount and issuance method, which are controlled by Tencent. The total amount and issuance method of Bitcoin are pre-set by programs and encryption algorithms, and run on multiple nodes around the world. No one or institution can modify them, and they are not controlled by any single person or institution. Q coins are generally called electronic currencies or corporate tokens. Bitcoin is called digital currency or encrypted digital currency.
2. What are the characteristics of blockchain? What can it be used for?
In summary, blockchain is the underlying technology of Bitcoin. It is like a database ledger that records all transaction records. Its essence It is a decentralized database. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience.
Blockchain has the characteristics of decentralization, no need for central trust, non-tampering, and encryption security. It is entering the vision of government decision-making, financial institutions, and large enterprises, and is used in digital currency, payment settlement, credit financing, and finance. trade.
What can blockchain be used for? From the current point of view, the most obvious application of blockchain is Bitcoin. Blockchain first gained attention thanks to Bitcoin.
Qian Lufeng, chief analyst of the computer industry at Sinolink Securities, said that the most typical application scenarios of blockchain currently include three categories:
The first is currency applications, such as Bitcoin, Ethereum, etc.;
The second is The traditional financial field, such as the blockchain technology alliance R3, Hyperledger, etc., brings together institutions such as Goldman Sachs, Ping An, HSBC, and IBM, and is committed to cross-border payment, financial bill management and other application scenarios in the financial field;
Three Right and Wrong The fields of Yuanzhou Finance include energy, luxury goods, telecommunications, Internet and other fields.
Listed companies in the A-share computer sector have actively deployed blockchain in aspects such as equity investment, technology research and development, and project cooperation. However, because it takes a certain amount of time to incubate a new team and new projects/products/services, many listed companies are still in the early trial and error stage in terms of blockchain technology research and development and scenario-based applications.
As for the application of blockchain in the financial and non-financial fields, Industrial Securities stated that many traditional financial institutions, including banks and exchanges, currently attach great importance to technologies such as distributed ledgers of blockchain. And began to explore its practical applications in cross-border payments, bill transactions, securities issuance, etc. Some industry leaders have already entered the concept verification and project implementation stages.
With the improvement and innovation of underlying algorithms such as consensus mechanisms, Internet companies and non-financial companies have also begun to explore the possibility of applying blockchain in non-financial fields such as supply chain management, copyright transfer, and case management.

④ What Tencent has done in the blockchain

Ma Huateng: Blockchain is OK; ICO is not OK

At the two sessions, Ma Huateng said that the topic of blockchain has recently been It’s so popular that some people even ridiculed that the Internet before blockchain was the “classical Internet.” Although blockchain technology is innovative, how to make good use of this technology is another issue.

In Ma Huateng’s view, blockchain technology can be applied in many fields, especially in the only way to digitally authenticate physical objects.Sexually. Just like a document, a ticket, etc. in reality, blockchain technology can be used to ensure that they cannot be copied or tampered with. Compared with traditional IT technologies in the past, blockchain is of epoch-making significance in truly simulating the uniqueness of documents and receipts in real society.

As for doing digital currency ICO, Ma Huateng believes that there are still many risks. He said: "If everyone can use blockchain technology to issue digital currencies at will, it will cause a lot of regulatory issues."

For example, gold was tested during the Spring Festival in 2017 The red envelope project is Tencent’s attempt to use blockchain technology to record users’ digital assets. In terms of public welfare tracing, Tencent also uses blockchain technology to reduce the problem of information asymmetry.

In addition to finance and public welfare, Tencent also reached a cooperation with Intel in September 2017, announcing that the two parties would jointly develop blockchain technology to improve security protection capabilities in Internet of Things scenarios.

⑤ Can you get a salary increase with the word "blockchain"?

Blockchain is a hot topic right now. Taking advantage of this popularity, various blockchain companies and blockchain platforms are coming from all directions. With the emergence of blockchain talents, blockchain talents have instantly become the biggest recruitment hot spot, with average salaries reaching 25,000 yuan, and the required talents are still in short supply.

On the recruitment website, Shanghai, Beijing, and Hangzhou have a greater demand for talents. The conditions and annual salaries given by companies recruiting "blockchain" related talents are about 500,000 to 800,000 yuan. Up and down, there are even promotions with an annual salary of one million. However, the current recruitment demand is still biased towards technical talents, such as blockchain system engineers, blockchain technology leaders and blockchain architects.

Companies are recruiting blockchain talents one after another, but the demand for talents is still insufficient. According to the "2018 Peak Season Talent Trend Report", in the first two months of 2018, the recruitment demand for blockchain-related talents has reached 9.7 times that of the same period in 2017. At the same time, the number of companies posting blockchain-related positions increased 4.6 times year-on-year, and the talent supply The volume increased by 235% year-on-year, but the stock is far lower than the actual demand.

⑥ Is there a salary bubble for blockchain jobs with an annual salary of one million?

At noon that day, 31-year-old Guo Yang (pseudonym) had just finished the morning technical meeting. There were seven or eight hours of technical discussions waiting for him. It was rare for him to take time off from work to have a meal with his friends. When he heard the other person say, "The annual salary of a blockchain technical director is 1.5 million," his hand shook and his bowl almost stopped. flipped.

Zhang Zuoyi’s current goal is to use the same method to complete the transformation of blockchain technology in other scenarios. He said that as the team does more and more, everyone will see that There are more than 300 online brands and nearly 8,000 products. Just like building blocks, cooperative relationships are being established based on cooperation with some brands.

Guo Yang is also very ambitious at the moment. At 9 o'clock in the evening, after working overtime, he had a meal with his friends in the company cafeteria and talked about the district.The latest progress of blockchain projects, I have experienced the ups and downs of the blockchain industry, and I have heard some sad or happy news. On the contrary, I feel that the blockchain technology is more viable and worth exploring. Thinking of this, I feel that my current job has released my ambition, and I look forward to building a career that truly belongs to blockchain technology.

⑦ Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralization A distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases. It makes transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly Payment transactions are carried out without the involvement of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
1.1 What is Blockchain
Blockchain (BlockChain) refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is 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 accountBook. Therefore, this data becomes very safe. 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.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress - people cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

Question 2: What is blockchain? What does it mean in layman’s terms? What is China’s attitude towards blockchain? What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. bitsOne of the most basic characteristics of currency is decentralization. In recent months, financial giants have gradually begun to pay attention to Bitcoin's technology and used it in non-monetary fields, such as stock trading, election voting, etc. (1) Art Industry
Artists can use blockchain technology to declare ownership and issue numberable, 100% edition works in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
(2), Real estate industry
Use blockchain technology to solve various problems faced by everyone involved in real estate, including the naming process, land registration, agency intermediaries, etc.
(3), Insurance Industry
The financial industry has always been the most sensitive to advanced technology. Traditional banking and securities industry giants have been involved in the booming blockchain venture capital investment since 2014, with total global investment reaching US$1 billion within two years.
(4) P2P wallet
Personal assets can be traded through this P2P wallet in the future without going through any central institution, such as Bitcoin.
Most blockchains are in their infancy, mainly overseas. There are very few good domestic blockchain projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and some applications in other aspects, the Internet of Things and so on.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open system with de-centered trust as the core.A value circulation network that allows digital assets to flow freely.
A simple understanding of blockchain is a technology underlying Bitcoin, which is also a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between Bitcoin, Bitcoin blockchain, blockchain and blockchain. Blockchain technology and other concepts. In countries with relatively developed finance in the past, finance and blockchain technology have a long history, and the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various equity, supply chain, points and other fields. Major domestic financial institutions and enterprises have taken a fancy to the new industry. value, they have developed their own blockchain platforms, and blockchain has instantly become a new innovative industry in China. In terms of overseas internationalization, the United States has already obtained 15 blockchain patents at the end of last year compared to China. Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will also become more and more profound. It has attracted more and more attention and will form a huge new trend... >>

Question 3: What is blockchain technology? What exactly is blockchain? What is blockchain? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through the data block, we can query each transaction record. A look at the history of Bitcoin transactions. 2. Example: There are three persons A, B, and C. All funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then: A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan from A's name, and add 80,000 yuan to B's name. If B transfers 50,000 yuan to A, C will add 50,000 yuan to A's name and subtract 50,000 yuan to B's name in the account book. A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name. 3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the network. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the network form Bitcoin’s distributed network database system. 4. The essence of data blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet centralization with data blocks.The dependence on the central server enables all data changes or transaction items to be recorded on a cloud system, which theoretically realizes self-certification of data during data transmission. In far-reaching terms, this goes beyond the traditional and conventional need to rely on a central server. The information verification paradigm reduces the cost of establishing global "credit". This point-to-point verification will produce a "basic protocol", which is a new form of distributed artificial intelligence and will establish a new interface between human brain intelligence and machine intelligence. and sharing interface.

Question 4: What is blockchain: This explanation of blockchain is more understandable. Blockchain refers to a technology that collectively maintains a reliable database through decentralization and trustlessness. plan.
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any 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 his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain technology has become the darling of the financial community in China and has become a hot topic. Domestic Puyin Group has launched Puyin, a tea-based digital currency.

Question 5: Explain in an easy-to-understand manner what blockchain is. Blockchain can be understood as a database system in a sense. The development of blockchain can be divided into 1.0 and 2.0
1.0 is represented by Bitcoin, and its main application is virtual currency or digital currency application. The blockchain at this time can only be used for simple digital currency transactions.
2.0 is represented by the now popular ethereum (Ethereum) and the upcoming hyperledger. The blockchain at this stage can not only meet the corresponding digital currency transactions, but also use smart contracts to customize currency or asset transactions. If we use the database analogy, the emergence of smart contracts can be understood as allowing users to define functions or stored procedures in the database and call and execute them.
Different from traditional databases, the blockchain introduces consensus mechanism, incentive mechanism, p2p (network), hash and other specific elements, making it open, decentralized and non-tamperable. characteristic.

Question 6: What is blockchain? Can anyone explain it in simple terms? Blockchain is the underlying technology of Bitcoin. It is like a ledger that records all transactions. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay it to Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. Without it, it means decentralization, just like buying things offline. If you pay with one hand and get the goods with the other hand, there is no third party.
The blockchain itself is a series of cryptographically related data blocks generated.
Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.
Many companies are developing this technology, including ours, and its prospects are incredible. For details, you can go to our official website and hope to adopt it, thank you

Question 7: What is blockchain technology? What is blockchain? How to explain the concept of blockchain? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
In the past six months, the concept of blockchain has gradually become popular in China, and a blockchain whirlwind has taken off in the financial circle. Blockchain has attracted the attention and favor of more and more people in the industry due to its unique technical advantages. Blockchain technology, which is decentralized (or multi-centered), highly transparent, cannot be tampered with, and has no single point of failure, is entering the field of vision of financial institutions and enterprises. It has at least been used in digital currency, payment exchange, registration and settlement, Digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussions to practical applications.
"Blockchain" was first introduced with "Bitcoin" released in early 2009. Blockchain has become the basic protocol and technical application for the launch, recording, and circulation of Bitcoin. Although Bitcoin has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities, the blockchain technology used in Bitcoin has been recognized by governments, including governments and monetary authorities. extensive attention.
Why has blockchain become a rapidly heating up hot technology and topic?
The most important of these may be that the launch of Bitcoin based on blockchain technology has opened up a new relationship with traditional society ( The exploration and attempt of brand-new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, notarization and verification, which have little connection with offline) and are fully applied in the online world (online), provide people with the opportunity to adapt to the Internet society. Development provides alternative paths and unlimited imagination.
Judging from its application in Bitcoin, blockchain is a set of new network blocks (BLOCK, also called communities) formed by combining encryption technology with the Internet.Bitcoin configuration, netizen identity verification, and Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (added block and transaction time identification, etc. Internet protocol rules and accounting (Ledger) system including block chain, full encryption, mutual authentication, etc., including factor) registration and verification. Precisely because Bitcoin is not a substitute for offline legal currency, but is issued and managed by non-legal currency authorities, mainly imitating the model of gold, and is completely new and decentralized protected and supported by basic Internet protocols and strict encryption technology. Internet currency (virtual currency) has thus formed a new set of currency rules and systems that are different from and not subject to real social laws, and can be bought, sold or exchanged with legal currency. It has been more than 8 years since Bitcoin was launched. There has been no record of funds or user information being stolen. Its security has been verified, and its efficiency and cost of fund settlement also have obvious advantages. This has made people's confidence in the blockchain technology used in Bitcoin continue to increase, and people have become more and more aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, the blockchain Chain is not the same as Bitcoin, and its application is by no means limited to Bitcoin. The application of blockchain can be decentralized or centralized; it can be a public chain model or a private chain model. Therefore, after Bitcoin, blockchain technology is also constantly developing and innovating, and constantly exploring new application areas, especially in the financial field.
The reason why blockchain is valued highly by more and more people is because the development and widespread application of the Internet have caused more and more economic exchanges and transaction activities to be conducted online, and the online world (or online world) society) is rapidly expanding, enriching and active, and online transactions must solve the efficiency and security protection issues of the parties' identity verification, value verification, transaction records, inspection and verification, etc., and require strict intermediaries and agreements (rules or constitutions). In this regard, traditional thinking and customary practices are to follow the development trajectory of the transfer of offline transactions to online and push the common rules and practices of the real (offline) society to the online (network) society. However, in practice, it is increasingly It is difficult to adapt to the needs of online transactions.
For example, for the identity verification of the parties, the natural choice is to use the information on the identity documents protected by the laws of various countries as the basis, and then add account or transaction passwords, as well as facial recognition, iris, fingerprints and other biometrics to conduct online transactions. Verification, but this method first makes the citizen identity information in the cross-border interconnected online world subject to the administrative jurisdiction of real society... >>

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain, soSo, together they are translated into blockchain.
1. Use cryptography technology to encrypt and decrypt so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has launched the digital currency crowdfunding platform Biying China.

Question 9: What is the so-called "blockchain"? Blockchain itself is a tool called decentralization and trustlessness. For example, when you graduate from university, the current practice is to have a certificate recognized and issued by an authoritative agency as your certificate. This setting is more troublesome, because this is a piece of paper, and paper can be forged, so there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, whoever There are various possibilities related to media. The blockchain provides a great opportunity. As soon as you graduate, you will have a record on the blockchain. No one can change this record. This thing exists objectively. You, as a physical existence , and then as a data existence, the blockchain was born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is similar to the big data often involved in social networking (WeChat) and payment platforms (Alipay, Yibao).

Question 10: What does blockchain mean? Regarding blockchain, I think you have already seen the concept on the Internet. Let me explain it based on my understanding!
First, let’s talk about its characteristics: 1. Openness and transparency 2. Decentralization 3. Anonymity 4. Information cannot be tampered with and eliminated 5. No trust cost
Blockchain is like a public ledger , everyone has the right to record and read, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be permanently saved, and can only be added but not deleted! However, as the number of blocks continues to increase, costs will increase and efficiency will decrease. (I’m not sure whether technology can be used to make up for this. I hope someone who understands technology can point it out.)
Blockchain is divided into public chain, private chain, and alliance chain. Public chain: accessible to everyone, everyone has read and write permissions, completely open, transparent and decentralized. privateChain: Open to individuals or institutions, in which the owner of the private chain can set various permissions to make it partially centralized. Alliance chain: Open to specific organizations or groups, it is also "partially decentralized". According to the ledger at the beginning, members can view and transact, but cannot record and confirm bills, or require permission from the alliance. (The latter two do not have cost and efficiency issues)
Regarding blockchain, countries have begun to recruit talents in this area. For this, you can search online for "Central Bank Recruiting Digital Currency R&D Personnel". In addition, you can increase your understanding of blockchain by understanding its existing applications. What we usually refer to generally refers to public chains. Currently, those used abroad include Bitcoin, Ethereum and other domestic blockchains. Chain
1. Open and transparent: Every piece of data is verified by everyone and can be viewed by everyone at any time.
2. Decentralization: For example, when we shop on Taobao, we conduct transactions through the intermediary Taobao, and blockchain allows both supply and demand parties to directly contact each other for direct transactions through blockchain technology.
3. Anonymity: No personal privacy information is required to complete transactions on the blockchain, only your unique alphanumeric signature is required.
4. Information cannot be tampered with or deleted: Once the data has been verified and recorded, no one has the authority to modify it, let alone delete it!
5. No trust cost: The trust crisis in reality will not appear in the blockchain. Transactions in the blockchain do not require you to trust the other party. Only when both of you have enough "digital assets" to trade can it be carried out, and Under the supervision of the entire network, transactions will not be broken. If you have no idea about the cost of trust, just think about how many intermediaries there are in your city, or just think about Jack Ma, and you will know how big the cost of trust is.
I am still learning more about blockchain. I am Li Ailin. If you have any questions, you can discuss and learn together!

⑧ Mars First Line | Tencent Virtual Bank has obtained a Hong Kong license and is preparing a blockchain virtual bank

Mars Finance APP reported that on November 8, the second World Blockchain Conference was held in Wuzhen.

He said that blockchain is still in the early stage of the explosion of applications. In the large-scale implementation of applications, the blockchain itself is no longer the bottleneck, but the gateway and auxiliary technology from off-chain to on-chain. is the key, which requires integration with cutting-edge technologies such as the Internet of Things and artificial intelligence.

⑨ It is rumored that Tencent will close the digital collection platform Huanhe

It is rumored that Tencent will close the digital collection platform Huanhe

It is said that Tencent will close the digital collection platform Huanhe Shut down the digital collection platform Huanhe. Huanhe is a digital collection platform owned by Tencent. It was launched in August 2021, less than a year ago. On July 2, Tencent News App suspended the sale of digital collections. Tencent is rumored to be shutting down its digital collection platform Huanhe.

It is rumored that Tencent will close the digital collection platform Huanhe 1

On July 20, according to Tencent insiders, Tencent is planning to abolish the "Huanhe" business this week. This news was reported in Huanhe Backbone (Tencent internal lower-level managers) have been communicated.

Huanhe is a digital collection platform owned by Tencent. It was launched in August 2021, less than a year ago.

On July 2, Tencent News App also suspended the sales service of digital collections. Within a month, Phantom Core also faced the same fate.

Wang Shimu, who is in charge of the Magic Core business, was just transferred to PCG’s social platform and application line in May and is responsible for the Magic Core and other innovative businesses that he led the team to incubate. Previously, he was the head of Tencent News.

In essence, domestic digital collections do not have the financial attributes of NFT, and there is no closed loop. But the more direct reason for the abolition of Magic Core is Tencent’s “cost reduction and efficiency improvement.”

It is a digital collection, not an NFT

When Magic Core was first launched, it was still announced to the outside world as the "NFT trading platform" owned by Tencent. The name change took place in October 2021. Some media discovered that the words "NFT" had disappeared in the Magic Core App and had all been changed to "digital collections."

The full name of NFT is Non Fungible Token, non-fungible currency. Its essence is a data unit on the blockchain digital ledger, and each token can represent a unique digital data. Because of their uniqueness, NFTs can be used to mark digital assets. Globally, the most well-known NFT project is Bored Ape Kennel Club, which is currently valued at US$4 billion (approximately 26.7 billion yuan).

Digital collections can be understood as NFTs with Chinese characteristics. They all have the characteristics of blockchain: they cannot be tampered with, indivisible, and cannot replace each other. But the essential difference is that the bottom layer of NFT is a public chain, which is completely decentralized.It is free from regulation and can be bought and sold freely. The bottom layer of Huanhe's digital collection is Tencent's Zhixin Chain, which cannot be traded in the open market. Users only have the right to "share and display".

This difference in underlying logic results in the complete removal of financial attributes from digital collections, but this is also the most valuable aspect of NFT. A collection that cannot be bought or sold and can only be viewed has basically no commercial value.

Ethereum, which the overseas NFT trading platform relies on, is a paid platform. You need to pay corresponding fees to put works on the chain, usually using virtual currency. However, relevant Chinese regulatory authorities have issued a series of regulations and policies that clearly prohibit the pricing and trading of virtual currencies.

For example, as early as 2013, the People's Bank of China and five other ministries and commissions issued the "Notice on Preventing Bitcoin Risks", which clearly stipulated that no exchange between legal currencies, tokens, and "virtual currencies" is allowed. For exchange business, you are not allowed to buy or sell tokens or "virtual currencies" or act as a central counterparty, and you are not allowed to provide pricing, information intermediary and other services for tokens or "virtual currencies".

The Magic Core team previously responded to the name change by saying that the digital collection business on the Magic Core platform adopts full-process real-name user procedures and full-link review of content, and does not allow the transfer of digital products between users. Resist illegal activities related to virtual currency.

Therefore, at the beginning of the launch of Magic Core, the first batch of 300 limited edition "Thirteen Invitations Vinyl Record NFT" was sold out within 1 second. However, in the past month, multiple numbers of Magic Core have The collection has become unsalable. A total of 20,245 pieces of "Master Hong Yi's Calligraphy Aphorism Screen Digital Edition" released by Huanhe on June 21 were unsold, and a total of 8,206 pieces of the series of woodblock watermarks "Shizhuzhai Painting Manual" released on June 17 were unsold.

As of July 20, 2022, there are no digital collections for sale in the Magic Core App. The latest digital collection on sale is the "Birds on Branches" series by Italian missionary Castiglione Castiglione. It was launched on July 8, and all 10 works in the series have not been sold out.

Tencent’s keyword of the year: cost reduction and efficiency improvement

In the 2022 Q1 financial report conference call, Ma Huateng once said that in the face of industry challenges, the company implemented cost control measures and Adjustments to some non-core businesses will help achieve a more optimized cost structure in the future.

In Q1 of fiscal year 2022, Tencent’s net profit was 25.55 billion yuan, a year-on-year decrease of 23%. This is Tencent’s third consecutive quarter of declining net profit.

At the same time, Tencent’s number of employees is also expanding. Tencent had approximately 116,200 employees in the first quarter of 2022, a year-on-year increase of 30.2%. Total remuneration in the first quarter of 2022 was RMB 29.229 billion, a year-on-year increase of 43.2%. Employee remuneration is already Tencent’s largest expenditure item.

Against this background, it is stillInnovative businesses that have not achieved a closed business loop have become the first targets for elimination.

According to Jiemian News, PCG has established a new GR (Gate Review) mechanism internally. If a project fails to meet expectations after reaching a certain stage of development, it will be shut down and adjusted. In February 2022, the shutdown of "Little Goose Pinpin" was the product of this mechanism.

Xiaoe Pinpin belongs to the NBase department of the Creation Camp, and its person in charge is Wang Shimu, who incubated the Magic Core.

Wang Shimu joined Tencent in August 2021 as general manager of Tencent News, reporting directly to Tencent COO Ren Yuxin.

Prior to this, he was the head of NetEase Cloud Music and successfully promoted it to become the leading product in the online music market.

After joining Tencent, Wang Shimu started the personalized recommendation reform of Tencent News, advocating the use of big data and algorithm recommendations to build Tencent News into a diversified content platform covering videos and communities.

But this transformation is far from successful. In Q1 2022, Tencent News’s advertising revenue fell by as much as 30%. Under the premise of "reducing costs and increasing efficiency", revenue has become an important internal assessment criterion within Tencent. In the past, the assessment criteria mainly focused on whether the brand of "Tencent News" has been improved, and the team did not need to bear too much revenue pressure.

Now, Wang Shimu is no longer the head of Tencent News. The previously hatched Little Goose Pinpin has been shut down, and Phantom Core is about to be abolished.

According to Sina Technology reports, Tencent insiders revealed that Tencent is planning to abolish the "Huanhe" business this week. lower level managers) have been communicated. Now Jiemian News has learned from an insider that this matter is basically true. Huanhe’s external business had ceased as early as early July.

Huanhe is a digital collection platform owned by Tencent. It was launched in August 2021, less than a year ago. It is worth mentioning that on July 2, Tencent News App suspended the sale of digital collections.

Domestic Internet companies, including Ant, Tencent, JD.com, etc., have all tested the digital collection business. With the first-mover advantage and the support of Tencent’s system, Magic Core has become the largest in the country One of the digital collection platforms.

Digital collections originate from the foreign concept of NFT. The full name of NFT is Non Fungible Token, non-fungible currency. Essentially, it is a data unit on the blockchain digital ledger. Each token can represent a unique digital data. Because of their uniqueness, NFTs can be used to tag digital assets. It is worth mentioning that since my country has always prohibited the speculation of virtual currencies, digital collections have shielded the financial attributes of NFTs, adopted alliance chain technology support, and restricted secondary transactions.

Analysts said that Tencent’s net profit fell by more than 20% in the first quarter of 2022, and Tencent’s net profit fell for three consecutive quarters. Tencent has recently implemented cost control measures and adjusted some non-core businesses. The abolition of the "phantom core" business may continue to reduce costs and increase efficiency.

Tencent has not yet responded.

It is understood that Magic Core is a digital collection platform owned by Tencent. It was launched in August 2021, less than a year ago. The initial technical support was provided by Alliance Chain to Xin Chain, and later Tencent Blockchain also became one of its technical supports. At the beginning of 2022, the Magic Core team revealed that it was developing a new online virtual space to take a step closer to the Metaverse.

Domestic Internet companies, including Alibaba, Tencent, JD.com, etc., have all tested the data storage business. With the first-mover advantage and the support of Tencent’s system, Magic Core has become the largest in the country One of the digital collection platforms. In the Tencent ecosystem, QQ Music and Tencent News have all tried digital collection-related businesses, and Magic Core is the most prominent representative among them.

It is reported that in the "Master Hong Yi's Calligraphy Aphorism Screen Digital Edition" series released by Huanhe on June 21, only the cover series one and seven were sold out, and the remaining 9 models were unsalable, totaling 20,245 pieces; A total of 8,206 pieces of the series of woodblock watermarks "Shizhuzhai Painting Book" released on June 17 were unsold. On the afternoon of June 23, Huanhe had locked up a large number of two unsalable collections and closed trading. Different from the "sold out/collected" marks on other digital collection details pages, unsaleable collections are marked as "ended".

It is worth mentioning that on July 2, Tencent News App issued the "Digital Collection Business Adjustment Announcement", announcing the suspension of digital collection sales services. Now the Phantom Core is facing the same fate. For the Tencent ecosystem, Magic Core is only one of its projects, but from an industry perspective, the departure of Magic Core will undoubtedly have a certain impact on the development of the digital collection distribution platform.

Analysts said that Tencent’s net profit fell by more than 20% in the first quarter of 2022, and its net profit has declined for three consecutive quarters. Against this background, innovative businesses that have not yet achieved commercial closure have become the first targets for abolition. The abolition of the phantom core business may continue to reduce costs and increase efficiency.

⑩ How to interview to join a blockchain company

It has been very difficult to find a job since 2018. It took me a long time to find a start-up company with less than 10 people. At that time, I was interviewing It was only then that I learned that it was a company engaged in digital currency exchanges and Dapps. At that time, I basically didn’t know anything during the interview. I thought there was no hope, but the next day I got a call telling me to come to work directly. I was so excited that I finally found him.Already working.
I have been working in this company for a year and a half since May 2018. I have been exporting works and rarely output some theoretical articles, so now I want to slowly sort out my work over the past year. Learn more about blockchain, how to do design, and prepare for those who are going to interview with blockchain companies.
