㈠ How Tencent responds to blockchain issues

Although Bitcoin has always had mixed reputations, the underlying technology blockchain that supports its development has been increasingly recognized and valued by all walks of life. . At the beginning of 2018, the popularity of blockchain has rapidly escalated again. Not only small start-ups, but also giant companies such as Tencent, Alibaba, Internet, and JD.com have also increased their investment in blockchain.

Tencent’s blockchain applications are in the stage of gradually blooming in many areas. Blockchain technology has been applied in supply chain finance, Tencent Micro Gold, logistics information, and legal evidence storage. , public welfare recruitment and other fields. In addition, Tencent also launched the blockchain open platform BaaS.

Cai Yige also revealed that this year he will promote the combination of blockchain and supply chain finance and launch an open platform for supply chain finance. At the same time, we continue to explore and implement in areas such as ABS platforms and virtual digital assets.

㈡ How to correctly view blockchain technology

From a technical perspective, blockchain is likely to be a major technological revolution after the Internet. Currently, major corporate giants around the world are working hard on the research and application of blockchain technology. SAP opened a pilot version of the blockchain project in May last year. Banks in Japan and South Korea have just begun testing blockchain technology. Tencent has registered the trademarks "Ether Lock" and "Tencent Ether Lock". In April 2017, Tencent released the "Blockchain Solution White Paper" and announced that Tencent's blockchain industry solutions with independent intellectual property rights were also officially released on the official website. The network has launched the blockchain open platform "BaaS", which is a project based on blockchain technology independently developed by the network. It mainly helps enterprise alliances build their own blockchain network platforms.

Xu Weihong, chief economist of AVIC Securities, believes that the concept of blockchain has been proposed for a long time. This round of being touted by speculators in the A-share secondary market originated from Bitcoin. Hype on a global scale. Participants do not care about the technical value of the blockchain, but they care about how much profit and water they can get from the existing "seigniorage" by creating digital currency through the blockchain. Some institutional investors even hope to use their professional judgment and ability to control market sentiment to "cut leeks" from the large amount of blind influx of social funds. In view of the recent rise of the blockchain concept, all parties concerned must remain sober. Financial exchanges and intermediaries must stay awake and reduce unnecessary advertising to mislead small and medium-sized investors, and ordinary people must also stay awake.

㈢ What is blockchain technology? What is blockchain? A chain data structure composed of sequential connections, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. security, leveraging smart contracts composed of automated script codeA new distributed infrastructure and computing method for programming and operating data.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal", of which "the minority obeys the majority" does not entirely meanThe number of nodes can also be computing power, number of shares, or other characteristics that computers can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

㈣ What is Tencent Blockchain and what are its specific application scenarios?

In fact, blockchain is a A kind of distributed database

㈤ Tencent takes the lead in establishing the first international standard project for blockchain digital collections

Specifically, this international standard will support the development of blockchain-based digital collection services. The standardization of technical architecture, technical processes, functional requirements and security requirements will help promote global recognition and consensus on the overall technical framework of digital collection services, enhance the value storage, value discovery and value transfer capabilities of digital collections, and promote digital collection services. Standardized application of collections.

It is reported that the International Telecommunication Union (ITU) is one of the three major international standardization organizations. Its members include more than 190 countries and more than 900 companies and academic institutions. It is the most influential and participating country and academic institution in the world. One of the most authoritative national standards organizations with the largest number of members. The successful establishment of this international standard project also marks that the technological exploration of my country's technology companies in the field of digital collections has been internationally recognized.

In fact, Tencent currently has rich practical experience in the field of digital collections. In July 2021, the Tencent Zhixin Chain team took the lead in launching the compliant and open digital collection technology service "Yuan Commodity Agreement" in China, which can accommodate various businesses to build a digital collection application platform based on the agreement. Only half a year after its launch, the Zhixin Chain team has successively supported the implementation of 30+ digital collection projects, including the "Fu" cultural digital collection project of the People's Cultural and Creative Industries, the public welfare digital cultural creation project of Dunhuang Research Institute, Tencent QQ music digital collection platform, Xiao Red Book R-SPACE collection platform, China Literature Digital Collection Platform, Tencent SSV “Dreams in Painting” digital charity project, etc.

At the same time, in terms of promoting compliance in the digital collection industry, Tencent has been actively advocating and participating in various industry self-discipline conventions, white papers, and industry standards.formulated to promote the standardized development of the industry. In September 2021, Tencent took the lead in establishing a project and formulating the group standard of "Blockchain Technology Digital Cultural Creation Application Specifications" at the China Blockchain Technology and Industry Development Forum; on October 31, 2021, Tencent and the National Copyright Trading Center Alliance, The China Academy of Art, Ant Group and others jointly released the "Self-Discipline Convention for the Digital Cultural and Creative Industry"; on December 22, 2021, the "Blockchain-Based Digital Collection Research Report" with Tencent core participation was published by the China Academy of Information and Communications Technology in the Trusted Blockchain Published at the summit.

㈥ How is the development of Tencent’s blockchain? What are the scenarios where blockchain concept stocks have been implemented? Is it a new outlet for getting rich?

In the field of blockchain, Tencent blockchain is developing relatively quickly. As early as 2015, the Tencent blockchain team has begun to pay attention to blockchain technology and conducted independent research and development. As of December 31, 2019, the number of Chinese invention patent applications related to Tencent blockchain reached 990, and in China Ranked first among applying companies. After several years of R&D and exploration, Tencent Blockchain has achieved good results in both the development of underlying technology and the construction of industrial ecology.

The development history of Tencent’s blockchain:

There are no technical problems, it’s just a question of whether to do it or not. ”

When asked what technical difficulties he encountered, Cai Yige, the head of Tencent Blockchain, answered this way. After thinking about it, he added that for theories such as secure multi-party computation and zero-knowledge proof, Technologies that have made breakthroughs in the past have not yet been engineered, which is an industry-wide problem.

For Tencent Blockchain, the bigger problem seems to be to find more scenarios. "Blockchain "Chain + supply chain finance" is a scenario that Tencent is promoting this year.

At the end of last year, the supply chain financial service platform Xingbei Cloud Chain was released, and its underlying blockchain technology is supported by Tencent Blockchain. In addition, Tencent also invested in Lianyirong, which was Tencent’s only strategic investment in supply chain finance.

Now that it has been almost a year, how is this scene and Tencent’s blockchain progressing?

Today, after the establishment meeting of the Blockchain Policy and Legal Research Group and the press conference of the "Blockchain and Supply Chain Finance White Paper", Odaily Planet Daily interviewed Cai Yige, General Manager of Tencent's Blockchain Business, and Lianyirong Company General Manager Ji Kun.

According to two disclosures, in less than a year of operation, the micro-enterprise chain platform has approximately tens of billions of transactions on the chain, with 12 banks connected and more than 70 Enterprises participate, involving industries such as energy, automobiles, and manufacturing. The current penetration supplier level is about level 1 and level 2, which can reduce the interest rate by 2-8 points compared with traditional bank loans.

Micro-enterprises The chain platform is Tencent's key case in supply chain finance. Tencent mainly provides the underlying technical infrastructure, including the underlying self-developed alliance chain, real-time clearing and account transfer capabilities; Lianyirong is mainly responsible for integrating resources and promoting the platform.

Supply chain finance is the leading scenario of blockchain, but its actual implementation is still very slow, which makes people doubt the substantial changes it brings. The two do not deny that this business is in a very early stage, and it will take some time to promote companies to join, but they both believe that "after joining the blockchain, supply chain finance will actually change a lot."

What Odaily Planet Daily wants to know more is, with the addition of supply chain finance after blockchain, will companies and financial institutions be more willing to join? And can this reduce the balance of small and medium-sized enterprise loans and increase the number of enterprises that receive loans?

“The biggest difficulty (in supply chain finance) lies in the participation of financial institutions, because they can only provide funds.” Ji Kun believes that the addition of blockchain can enhance banks’ willingness to enter supply chain finance.

In his opinion, the traditional banks of the four major banks are quite keen on the layout of blockchain. He said that supply chain finance itself is decentralized and the authenticity of underlying assets is very difficult to check. It is not mainstream in traditional financial institutions, and there was no way to achieve penetration before, so banks can only obtain the data of first-tier suppliers. But those in greatest need of financing may be second- and third-tier suppliers. Now blockchain + supply chain finance has changed the credibility of multi-level data circulation, strong credit cannot be split, and the synchronization efficiency of information, making it difficult for small, medium and micro enterprises in the supply chain to obtain loans from financial institutions in the past. Can get a loan. Banks have always wanted to do business with second- and third-tier suppliers. By joining the blockchain, institutions can better control their own data.

As for promoting enterprise use, Ji Kun said that it will take a certain amount of time for many enterprises to accept it. However, because the blockchain of supply chain finance mainly replaces the role of the original commercial paper, the circulation of the commercial paper itself There are some pain points, such as fraud, so they are relatively easy to accept.

When Odaily Planet Daily asked about how to ensure the authenticity of on-chain information, Cai Yige said that different information can be cross-verified, but he also believed that this was indeed a problem, using blocks The chain does not guarantee the authenticity of the information on the chain. Therefore, the first step of the micro enterprise chain's assets is actually accounts receivable, and it is true to use invoices to protect the underlying assets. As the business systems of small and medium-sized enterprises become electronic, they will go deeper in the future.

He also added that blockchain can also improve the efficiency of information synchronization. "I think it is the control of information. It turns out that in a centralized situation, even if you have information, it can be tampered with."

After talking about the focus of Tencent Blockchain this year, everyone naturally wants to know the future plan of. However, Cai Yige’s answer was the same as at the beginning: “We can’t talk about plans. We will continue to think about the scenarios in which blockchain can exert value.”

About this development:

First, you must choose the right scene and be sure to find experts in this industry.

Second, it must be in line with the nature of technology and have commercial value.

Third, it must meet the needs of future development.

Fourth, architectureTo truly solve the problem, it must be fully integrated with other technologies.

The concept of blockchain should be a new trend. Specifically, make more use of Internet searches to increase knowledge. Internet search results-Tencent Blockchain Development will be put for you.

㈦ What is Tencent Blockchain?

Answer: "Blockchain is a decentralized, trustless, distributed and consistent storage system. Tencent Blockchain There is no specific definition of currency yet, but there are many blockchain-related exploration studies and services. Auditing is always done after the fact, but blockchain can intervene before and during the event. For example, in WeChat payment, QQ wallet, financial management Financial services such as Tongtong and Q Coin can establish blockchain wallets. Blockchain technology maintains continuity in time and openness in space, and ensures the traceability and tamper-proofing of information through systems and procedures. , forming a three-dimensional, transparent and true credit management system. Blockchain can essentially replace the responsibilities of many central institutions. Compared with machines and people, machines will never lie, so this is a possible opportunity for us in the future."< br />Another example is other industries: securities, P2P, personal resumes, education, hospital medical records, electronic invoices, etc., wherever credit risks and financial risks may occur, blockchain can be used for supervision. Even our internal systems can be designed based on blockchain concepts to improve security and governance. In the blockchain, trust and efficiency become two balancing factors. Pursuing maximum trust will lead to low efficiency. If you pursue maximum efficiency, trust risks will increase accordingly. Each type of blockchain has different characteristics and needs to be selected based on business characteristics. No matter which type is adopted, user privacy and information security are the first consideration, which is the cornerstone of the entire system.

Tencent Cloud’s blockchain financial-grade solution integrates Tencent’s multi-party business including resources in many industry-leading fields such as payment, social networks, media networks, and credit reporting platforms, as well as in smart contracts. , mutual insurance, big data transactions and asset transactions, supply chain finance and supply chain management, can provide financial users with safe, reliable and flexible blockchain service technology support.

Blockchain first avoids the traditional cross-border payment, clearing and auditing and other financial aspects. The inter-bank settlement steps are relatively cumbersome, resulting in slow settlements from time to time, and the payment time is long and investment-intensive. The cost is relatively high. In the traditional insurance industry, the document process that insurance companies need to process takes a relatively long time, resulting in huge time costs. Secondly, in the field of mutual insurance in the field of crowdfunding, there are risks of cheating on the platform, difficult supervision, and opaque public welfare funds and accounts, resulting in the inability to transmit trust. The industry also needs the regulation and supervision of the financial transaction system.

With the popularization and application of the Internet, traditional finance has undergone the evolution of the informatization, networking, and digital era, and has far exceeded the traditional connotation of financial integration. The financial technology that drives financial development is being transformed by the mobile Internet, Big data, cloud computingand other application levels, further turning to the innovation level of underlying technologies such as blockchain. The huge strategic value of blockchain has also triggered competition in the global financial industry. Under the trend of the times, Tencent’s blockchain layout must have Great work.

Tencent’s blockchain open platform has refined two service models, one is shared ledger and the other is digital assets. There are problems such as information asymmetry and low transmission efficiency between people. Sharing ledgers allows everyone to work together as equals to complete one thing. Tencent's blockchain has achieved joint application in multiple industries such as banking, insurance, securities, supply chain finance, etc. Blockchain is becoming a new open sharing gene in Tencent's eyes.
Looking forward to the day when our Internet will no longer be filled with confusing information that is difficult to distinguish between true and false, but an Internet full of vitality and trust, where information is truly open and transparent. This is the greatest meaning and value of blockchain.

㈧ What is blockchain

[Definition]

Blockchain refers to collective maintenance through decentralization and trustlessness. A technical solution for a reliable database. This technical solution allows any number of nodes participating in the system to calculate and record all information exchange data in the system over a period of time into a data block (block) through cryptographic algorithms, and generate the fingerprint of the data block for linking ( chain) and check the next data block, all participating nodes in the system jointly determine whether the record is true.

Blockchain is a general term for technical solutions similar to NoSQL (non-relational database). It is not a specific technology. Blockchain technology can be implemented through many programming languages ​​and architectures. . There are also many ways to implement blockchain. Common ones currently include POW (Proof of Work), POS (Proof of Stake), DPOS (Delegate Proof of Stake), etc.

The concept of blockchain was first proposed in the paper "Bitcoin: A Peer-to-Peer Electronic Cash System" by the author who calls himself Satoshi Nakamoto (Satoshi Nakamoto) individual (or group). Therefore, Bitcoin can be regarded as the first application of blockchain in the field of financial payments.

[Popular explanation]

No matter how big the system or how small the website, there is usually a database behind it. So who will maintain this database? Under normal circumstances, whoever is responsible for operating the network or system will maintain it. If it is a WeChat database, it must be maintained by the Tencent team, and Taobao's database isAlibaba's team is maintaining it. Everyone must think that this approach is natural, but this is not the case with blockchain technology.

If we imagine the database as a ledger: Alipay, for example, is a typical ledger, and any change in data is an accounting type. We can think of database maintenance as a very simple accounting method. The same is true in the world of blockchain. Everyone in the blockchain system has the opportunity to participate in accounting. The system will select within a period of time, maybe within ten seconds, or maybe ten minutes, to select the person with the fastest and best accounting during this period. This person will do the accounting, and he will combine the changes in the database during this period with Changes in the ledger are recorded in a block. We can imagine this block as a page of paper. After confirming that the record is correct, the system will link (chain) the data fingerprint of the past ledger to this paper, and then This piece of paper is sent to everyone else in the entire system. Then the cycle starts over and the system looks for the next person who can do the accounting quickly and well, and everyone else in the system gets a copy of the entire ledger. This means that everyone in this system has exactly the same ledger. This technology is called blockchain technology, also known as distributed ledger technology.

Since everyone (computer) has exactly the same ledger, and everyone (computer) has exactly the same rights, there will be no problem due to a single person (computer) losing contact or going down. The entire system collapses. Since there are exactly the same ledgers, it means that all data is open and transparent, and everyone can see the digital changes in each account. Its very interesting feature is that the data in it cannot be tampered with. Because the system will automatically compare, it will consider the account books with the largest number of the same number as the real account books, and the small number of account books with different numbers as others are false account books. In this case, it makes no sense for anyone to tamper with their own ledger, because unless you can tamper with most of the nodes in the entire system. If the entire system has only five or ten nodes, it may be easy to do, but if there are tens of thousands or even hundreds of thousands of nodes, and they are distributed in any corner of the Internet, unless someone can control most of the computers in the world , otherwise it would be unlikely to tamper with such a large blockchain.

[Elements]

Combined with the definition of blockchain, we believe that it must have the following four elements to be called a public blockchain technology. If it only has the first three points elements, which we will consider as private blockchain technology (private chain).

1. Point-to-point peer-to-peer network (peer-to-peer power, physical point-to-point connection)

2. Verifiable data structure (verifiable PKC system, non-tamperable database)

3. DistributedConsensus mechanism (solve the Byzantine generals problem and double payment)

4. Nash equilibrium game design (cooperation is an evolutionarily stable strategy)

[Features]

Combined with the definition of blockchain, blockchain will realize four main characteristics: decentralized, trustless, collectively maintained, and reliable database. ). And the four characteristics will lead to two other characteristics: open source (Open Source) and privacy protection (Anonymity). If a system does not possess these characteristics, it will not be considered an application based on blockchain technology.

Decentralized: The entire network has no centralized hardware or management organization. The rights and obligations between any nodes are equal, and the damage or loss of any node will not affect it. operation of the entire system. Therefore, the blockchain system can also be considered to have excellent robustness.

Trustless: Each node participating in the entire system does not need to trust each other for data exchange. The operating rules of the entire system are open and transparent, and all data contents are also public. , therefore within the rule range and time range specified by the system, nodes cannot and cannot deceive other nodes.

Collectively maintain: The data blocks in the system are jointly maintained by all nodes with maintenance functions in the entire system, and these nodes with maintenance functions can be participated by anyone.

Reliable Database: The entire system will be divided into databases so that each participating node can obtain a copy of the complete database. Unless more than 51% of the nodes in the entire system can be controlled at the same time, modifications to the database on a single node are invalid and cannot affect the data content on other nodes. Therefore, the more nodes and stronger computing power participating in the system, the higher the data security in the system.

Open Source: Since the operating rules of the entire system must be open and transparent, for the program, the entire system must be open source.

Privacy protection (Anonymity): Since nodes do not need to trust each other, there is no need to disclose their identities between nodes. The privacy of each participating node in the system is protected. protected.

㈨ On the blockchainWhat Tencent did

Ma Huateng: Blockchain, OK; ICO, no

At the two sessions, Ma Huateng said that the topic of blockchain has been very hot recently, and some people even made fun of blockchain before The Internet is 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 digitally authenticating the uniqueness of physical objects. 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.
