❶ FISCO - Golden Chain Alliance creates a new era of public alliance chains

Public chains, alliance chains (permissioned chains) and private chains can be said to basically include blockchains Three ways to use technology. In recent years, the planning, financing, development and ecological construction of the public chain can be said to have been carried out in a noisy manner. Some are real, and there are even more deceptions. It is noisy, noisy, muddy and sandy, and investors' money has really gone in. But not many are online, and the ecological construction of the few public chains that are online is also sparse. There are very few DApps, and the daily activity is even less. In short, not many current public chain projects can or are willing to survive. Ecological construction is even further away.

Private chains are self-built and internally run blockchain architectures of respective companies and institutions. Very little information is disclosed, but I believe that using your own money to do your own things and solve your own problems will not cause any problems. What a big deal.

The development of the alliance chain has always been low-key. Since blockchain technology was recognized by the mainstream economy and society, pragmatic mainstream economic institutions have been solidly carrying out research, development and application for about 4 years. During this period, the backbone of the alliance chain was formed, and another correct path was found for the implementation of blockchain applications and ecological construction. In a certain sense, the alliance chain has passed its infancy and has begun to solidly move towards the "public alliance chain" new era. The alliance chain's naturally strong relationship with mainstream economic industry resources also determines the alliance chain's mainstream status in the application prospects of blockchain technology.

With the dawn of the digital economy era and the popularization of distributed business models, blockchain technology has also been able to give full play to its advantages and become a representative of cutting-edge technology. In 2016, three companies, WeBank, a member of the Golden Link Alliance, Shanghai Wanxiang Blockchain, and Matrix Yuan, a member of Chinaledger, reached a strategic cooperation and jointly committed to exploring blockchain technology, and

The full name of Golden Link Alliance is Financial Blockchain Cooperation Alliance (Shenzhen). It was jointly established on May 31, 2016 by more than 20 financial institutions and technology companies including Shenzhen Financial Technology Association, Shenzhen Qianhai WeBank, and Shenzhen Securities Co., Ltd. Non-profit organization established. As an open organization, Financial Institutions that voluntarily abide by the charter and companies that provide technological services to financial institutions can apply to join. So far, members of the Golden Link Alliance include more than 80 institutions in six major industries including banks, funds, securities, insurance, local equity exchanges, and technology companies.

On November 26, 2016, Golden Chain Alliance released the "Financial Distributed Ledger Proposal", proposing five major principles such as legal compliance, traceability, security, privacy protection, and business orientation, as well as a value alliance , autonomous and controllable, safe and trustworthy, efficient and available, business feasible, flexible configuration, intelligent supervision and other seven propositions.

Purpose: Integrate and coordinate financial blockchain technologyResearch resources, form a synergy and coordination mechanism for financial blockchain technology research and application research, improve the research and development capabilities of member units in the field of blockchain technology, explore, develop, and implement financial alliance blockchain suitable for financial institutions, and application scenarios based on this.

The General Assembly of the Golden Chain Alliance is the highest authority; the permanent body of the General Assembly is the Presidium, which leads the alliance to carry out daily work during the intersessions of the General Assembly and is responsible to the General Assembly; the Presidium has a technical committee (chaired by Application project work), Standards Technical Working Committee (presides over the establishment, formulation, review and release of standards), Advisory Committee (organizes external experts to participate in technical and standards discussions).

Jinlianmeng has set up research directions in the fields of credit, equity, points, insurance, bills, cloud services, digital assets, financial product issuance and trading, and some of the projects have now been implemented or products have been launched. prototype.

The FISCO BCOS underlying blockchain platform is jointly built by the FISCO open source working group. Members of the working group include Beyondsoft, Huawei, Shenzhen Securities Exchange, Digital China, Sifang Innovative, Tencent, WeBank and Yuexiu Jinke and other members of the Golden Link Alliance, aiming to create a secure and controllable blockchain suitable for the financial field. The underlying platform of the chain.

Financial services are one of the earliest application areas of blockchain. Blockchain technology brings advantages such as safety and reliability, simplified processes, cost savings, reduced operational risks, and increased trust, and has the potential to reconstruct and sublimate the original financial industry infrastructure. The financial industry focuses on multi-party reciprocal cooperation and has strong supervision and high-level security requirements, which require node access and authority management. Therefore, the technical direction of the alliance chain has become the main choice for the financial industry.

At present, my country's financial industry is opening up to the outside world with unprecedented intensity, and the pace of financial innovation is also accelerating. Therefore, how to effectively balance the relationship between open innovation and risk prevention and firmly maintain the bottom line of no systemic risks is an important issue for the industry. challenges that urgently need to be addressed.

From the perspective of financial IT infrastructure, there are still some shortcomings and pain points in operational risks, moral hazards, credit risks, information protection risks, etc.

First, financial IT system data may still be tampered with, forged, or have consistency differences.

Second, the infrastructure structures and business processes of different financial institutions are different, and even still involve many manual processes, which greatly increases operating costs and is also prone to operational risks and ethics. risk.

Third, financial business and financial cooperation may involve multiple participants or intermediaries, which can easily increase trust costs and friction costs. There is also a certain degree of mutual trust and collaboration.or cooperative equivalence issues.

Fourth, financial business is often highly complex, and it is easy to miss records of all business elements. Sometimes it is difficult to trace the entire business process, and it cannot meet the needs of supervision and auditing.

Fifth, the data between different financial institutions are relatively independent, making it difficult to achieve safe and efficient interaction, resulting in high costs for repeated KYC, anti-money laundering, and anti-fraud, and also indirectly causing the loss of user data. Risk of being leaked by certain intermediaries.

Sixth, the availability and adaptability of centralized IT infrastructure are weak, and distributed technologies need to be used to improve robustness or adaptability.

As a combined infrastructure solution, blockchain technology can in principle respond to the needs of the financial industry. However, because the requirements of the financial industry are more diverse and strict, as a financial version of the blockchain solution, it needs to be based on the blockchain technology of the universal industry and according to the special business needs of financial institutions, existing technical levels, and laws and regulations. Requirements or conditions in other aspects shall be comprehensively considered from multiple dimensions such as business suitability, performance, security, policy, technical feasibility, operation and maintenance and governance, and cost.

First, the appropriateness of the business scenario. Not all financial business scenarios require the use of blockchain technology. Generally speaking, when it comes to scenarios involving multi-party participation and peer-to-peer cooperation, the traditional centralized system architecture is often difficult to meet the needs, so you can consider using blockchain technology. This will increase multi-party mutual trust, improve business operation efficiency, and reduce business operation costs and friction costs.

Second, the performance of the blockchain system. Financial business often has characteristics such as massive transactions, high-frequency transactions, and timely confirmation. Therefore, the blockchain open source platform in the financial industry needs to analyze the business volume, potential business growth scale, and potential business growth scale that the blockchain system needs to support based on the current business scale of financial institutions. Technical performance index requirements such as concurrent business volume and response time. Since blockchain platforms using different technical modules, such as different consensus mechanisms, have greatly different performance support, it needs to be evaluated based on business performance requirements and combined with blockchain performance efficiency indicators.

Third, the security of the blockchain system. Blockchain can ensure the credibility of recorded data from a technical level and prevent data from being tampered with, forged and other risks. In addition, in terms of data sensitivity and security, it is necessary to evaluate the content encryption strength of the on-chain data, as well as access control, etc. Financial institutions need to choose mature, appropriate, and secure encryption algorithms based on the specific security requirements of their business.

Fourth, policy compliance. Blockchain is a set of technical solutions that, with reasonable design, can provide good support for existing businesses or complement existing centralized systems. However, when financial institutions use blockchain to conduct business, they must implement it within the country's existing regulatory requirements and legal framework.

Fifth, technical feasibility. Blockchain technology has already been implemented in some financial scenarios, but it is still an emerging technology. It is necessary to fully evaluate the fit of the technology with specific businesses and its advantages and disadvantages compared with traditional systems before finally choosing the appropriate area. Demonstration and trial operation of the blockchain platform.

Sixth, operation and maintenance and governance capabilities. Since there are differences in operations and management between blockchain-based businesses and traditional centralized systems, and the continuous governance requirements of financial businesses are extremely high, corresponding planning and adjustments are required to evaluate the feasibility and sustainability of the new governance structure. , evaluate the impact of version iterations and the official launch of the system, monitor the operation of the blockchain system in real time, and ensure business controllability and financial environment stability.

Seventh, costs are controllable and economically feasible. Blockchain applications use technical features to solve specific problems in actual business. Applications that effectively solve pain point problems can bring great benefits to financial businesses, and the value of the application itself can also be revealed; on the contrary, if it cannot solve important problems in the industry , you need to face a trade-off between costs and benefits.

If a safe and reliable underlying financial blockchain platform can be built to meet the special needs of the financial industry, blockchain technology will be of great use in the financial industry.

For example, from the perspective of banking institutions, the key exploration directions are generally to apply blockchain technology to reduce clearing and settlement costs, improve middle and back-office operational efficiency, improve process automation, and reduce operating costs. In addition, in cross-border financial scenarios, blockchain can help realize ledger sharing among cross-border financial institutions, reduce reconciliation and settlement costs and dispute friction costs between cooperative banks, thereby improving the processing speed of cross-border business. and efficiency.

From the perspective of non-bank financial institutions, blockchain can be used to improve the authority of rights registration and information storage, reduce counterparty risks, solve data tracking and information anti-counterfeiting issues, and reduce audits. operating costs, etc.

From the perspective of financial regulators, blockchain provides regulators with consistent and easy-to-audit data. Through data analysis of inter-institutional blockchains, the audit process can be faster and more efficient than traditional audit processes. Precisely regulate financial operations. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly strengthen anti-money laundering efforts.

Designed an efficient, reliable, message communication protocol based on the blockchain network, referred to as Advanced Messenger On-chain Protocol AMOP (Advanced Messenger On-chain Protocol), focusing on the following functions:

 Based on the blockchain network, it supports inter-bank and point-to-point real-time message communication;

 Provide standardized interfaces for the interaction between off-chain systems and blockchain;

 The blockchain system can actively call the business interface of the off-chain system;

The technical characteristics of this protocol are:

 In a point-to-point blockchain network topology, plan node communication paths to ensure message reachability;

 It can quickly sense node abnormalities in the blockchain network and automatically switch paths to resend messages;

 Use encryption technology during the communication process to ensure privacy at the communication layer.

Designed the contract naming service CNS (Contract Name Service). The design goal of CNS is to name the correspondence between the business layer and smart contracts, so that the business layer no longer cares about the relevant contract addresses. Similar to DNS on the Internet, the use of domain names makes it easier for users to remember how to access a website, and also gives the website great flexibility in terms of clustering, migration and expansion.

The most watched champion project - ODRChain, based on FISCO BCOSIt uses blockchain technology to solve the pain points of traditional judicial processing of online disputes, such as the difficulty in verifying the authenticity of electronic data and the inability to digest a large and rapidly backlog of case disputes.

At present, ODRChain has shortened the time it takes for customers to go from clicking "one-click arbitration" to receiving the arbitration award, from the traditional arbitration process that lasted several months to about 7 days. , and the arbitration fees that originally cost tens of thousands of dollars have been reduced to a few hundred yuan. As of December 2018, ODRChain has completed the deposit of over 10 million contracts, involving hundreds of billions of funds.

First prize: JustSign - a white-box cryptographic algorithm that turns a mobile phone into a USB shield

The project that grabs the first prize in the competition - JustSign, is based on FISCO BOCS It is an electronic contract signing and certificate storage system. Its original JustKey white-box cryptographic algorithm realizes "mobile phone as USB shield", which solves the problem of limited compatibility of traditional CA, inability to protect key security on the mobile terminal, and vulnerability to attacks in centralized data storage. question.

Expert reviewers commented that electronic contracts involve complex legal relationships and ownership of interests, and it has long been difficult to achieve a balance between security, integrity and portability. The team’s original white-box cryptographic algorithm is really conducive to improving security in blockchain certificate storage scenarios.

Second Prize: Internet of Things Trusted Interconnection Solution - The Picture of Smart Life Looks Like This

The Internet of Things Trusted Interconnection Solution competed by Sichuan Changhong Security Laboratory depicts Come up with a smart home blueprint that requires almost no extra worry on your part. When analyzing the blockchain technology behind it, a team representative said that an inter-enterprise cooperation alliance is established based on the alliance chain to open up the interconnection and mutual trust of IoT devices between different manufacturers, and based on insights into typical business scenarios of smart life, through smart contracts Implement smart terminal registration, scene rules, trust rules and linkage rules.

Expert judges of the competition believe that this project has practical hardware and scenarios in the field of Internet of Things, and is expected to further promote the implementation of application scenarios such as distributed AI assistants, resource sharing, life cycle management, and multi-channel payment. Truly usher in smart life.

Among the projects that won the third prize in the competition, they accurately targeted the characteristics of blockchain in terms of security and efficiency improvement, and provided practical solutions for the industries they represented. Tsinghua University The team of teachers and students found a new way to develop cross-layer full-stack blockchain security detection technology to protect other blockchain applications comprehensively, and its technical strength was highly praised by the judges.

The third prize winners were the trusted electronic certificate platform of Shenzhen E-Commerce Security Certificate Management Co., Ltd., the real estate registration platform of Wuhan Liandong Times Technology Co., Ltd., and Shandong Guanhai Data Technology Co., Ltd. The company's Rongcheng blockchain service platform,The animal husbandry blockchain traceability of Quanliantong Co., Ltd., the tourism finance alliance platform of Shenzhen Youxun Information Technology Co., Ltd., and the copyright safe deposit box of Beijing FamilyMart Technology Development Co., Ltd.

Shanghai Jiuyaojiu Information Technology Co., Ltd.’s first-responder mutual aid first aid, “Yongteng Group My Innovate”’s HaveFund, Qianhai Life Insurance Co., Ltd.’s blockchain policy management, “Huazhong Technology The university's Guanshankou Hulu Brothers' Book Campus and the Cloud Block project team's "Yun Block" account system also won the competition's Outstanding Social Value Award, Outstanding Business Design Award, Outstanding User Value Award, Outstanding Creativity Award, and Outstanding Application Integration Award respectively.

Ma Zhitao, chairman of the Golden Alliance Technical Committee, elaborated on the concept of the “public alliance chain”. He believes that the alliance chain should achieve self-sublimation and should be able to evolve into an ecosystem that provides services to the public, that is, a "public alliance chain."

Different from the public chain project’s idea of ​​“coming up with a plan first, raising funds, vigorously promoting it, raising the price, and finally investing in development”, the alliance chain project adheres to the idea of ​​“investing in development first with its own funds” , go to the production environment to verify, accumulate real customers and users, run steady trials and errors, and finally carry out promotion and publicity.” However, due to the focus on practical implementation and focusing on real applications, there is a lack of publicity, and it has no choice but to fall into a passive situation of "many people have implemented it, but few people have praised it". Golden Chain Alliance hopes that through this competition, the project team of the alliance chain will come to the stage to show their results, enhance the influence of the alliance chain, and let the public know more about the real application implementation and sustainable development of the alliance chain project.

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

71. Who is Satoshi Nakamoto?

72. Bitcoin is different from Q Coin

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

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

73. What is a mining machine?

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

74. What is quantitative trading?

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

75. Blockchain asset over-the-counter trading

Over-the-counter trading is also called OTC trading. Users need to find counterparties by themselves, without matching transactions. The transaction price is determined by negotiation between the two parties. The two parties can fully communicate through face-to-face negotiation or telephone communication.

76. What is a timestamp?

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

77. What is a blockchain fork?

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

78. Soft fork and hard fork

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

79. Classification and application of blockchain projects

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

80. USDT against the US dollar

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

81. Altcoins and alternative coins

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

Smart Contract is a computer protocol designed to spread, verify or execute contracts in an information-based way. Simply put, in advance Set up an electronic contract, and once both parties confirm it, the contract will be automatically executed.

96. What is a token?

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

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

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

99. Five characteristics of digital currency

The first characteristic: decentralization

The second characteristic: having open source code

The third feature: independent electronic wallet

The fourth feature: constant issuance

The fifth feature: global circulation

100. What is decentralization?

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

100. What is measurement (scarcity)?

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

101. What is open source code?

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

102. What is anonymous transaction? Private wallet private?

❹ Blockchain financial application innovation platform, chain application, how to operate bonds

Blockchain financial application block Preparation before chain bond operation Blockchain + bond blockchain has unique advantages, it is possible to replace traditional securities issuance methods and trading models, establish a new blockchain securities market network, and complete certification, confirmation, issuance, trading, Traceability and other work can also help eliminate fraud, breach of contract
and other behaviors, and achieve real-time penetration supervision. traditional debtBonds and Blockchain Bonds The biggest difference between traditional bonds and blockchain bonds is that the traditional model is based on centralized point-to-point bonds. The center may be an intermediary or an electronic account, while blockchain bonds are decentralized or disintermediated. The point-to-point circulation of bonds will help improve efficiency and solve problems such as information asymmetry. Blockchain + IPO makes IPO-related information transparent and public through the blockchain, allowing investors to follow traces and increasing their fraud costs. Building a consortium chain By forming a consortium chain and deploying bond issuance on the blockchain to achieve point-to-point issuance, the role of securities underwriting institutions can be weakened and underwriting fees can be reduced. Smart bonds (create smart contracts) When a certain transaction condition is met, both parties to the bond transaction complete the transaction according to the pre-agreed securities transaction price and transaction quantity. Such a contract is turned into code and written into the blockchain. Once the conditions are triggered, the blockchain system will automatically start the payment code of the smart contract, and the securities and other valuable assets involved will be automatically traded according to the contract and processed in real time. Complete clearing and delivery. It effectively simplifies the default behavior of issuers. Smart securities avoid the manual process of traditional financial transactions and save time and costs. Its design allows both parties to securities transactions no longer rely on third-party credit intermediaries. It also helps to speed up transactions while reducing Human error and operational risk.

❼ What are the good blockchain application development platforms currently available in China

Whenever Dilemma Hong mentioned decentralized application platforms, we always thought of foreign blockchain solutions. , but when we talk about this topic today, we think more about our own domestic Laikelib

The underlying architecture of Heshu Laikelib blockchain technology under Shanghai Heshu Software is a decentralized blockchain application The Wangce platform was developed to help developers quickly create decentralized applications

Laikelib is easy to use, flexible, convenient and safe

In terms of model, it is similar to Ethereum They all belong to the underlying technical architecture services of the blockchain, but the implementation mechanisms are still slightly different. This can be learned on the official website of Heshu Blockchain Technology

❽ "Blockchain - Financial Black Technology"Above Shanghai Jiao Tong University

The theme of this lecture is "Blockchain - Financial Black Technology". The speaker is Mei Wenxiang, the co-founder of Kuoyue Technology, and also the global leader of Ethereum's original chain ETC The founder of the largest mining pool 91pool. This lecture attracted many students, and even though it rained heavily that day, the venue was still full.

Before the lecture officially started,
Mei Wenxiang asked three questions:
How many students know about Bitcoin?
How many students know about blockchain?
How many students know about smart contracts?
Just judging from the hands raised at the scene, even if they are facing a new knowledge and new field - "blockchain", Jiaotong University students have done their homework in advance before listening to the lecture.

Mei Wenxiang talked about the basic knowledge of blockchain from three aspects: the origin of blockchain, blockchain, and smart contracts. First of all, the speaker used humorous language and vivid metaphors to tell everyone that although it is less than 10 years ago, the current development of blockchain is like physics-magnetic field, "invisible and intangible, but objectively existing", " "Bitcoin" is the first "son" of "blockchain". The three characteristics of blockchain, "shareable, trustworthy, and shared ledgers," determine that blockchain will become a more powerful technology in the near future.

I came into contact with "blockchain" 3 years ago. Even though I have been working in the Internet finance industry for 6 years, I resolutely chose to get back on the road and began to explore the research and application in the field of blockchain, and soon after Founded WNT Kuoyue Technology and officially started many practices of blockchain applications, such as: "91 Charter" of the blockchain financial leasing platform, "Yijian" of the blockchain art appraisal platform and "Yijian" of the digital currency production platform. 91 Coin Pool”.

Wonderful question-and-answer session

As the lecture came to an end, students from Jiaotong University actively raised their own questions to the speaker. The speaker answered them patiently and frankly said that blockchain Learning is a process that cannot be rushed.

At this point, the lecture ended successfully.
