3. Blockchain Is the Blockchain Technology Application Innovation Competition difficult?

The Blockchain Technology Application Innovation Competition is difficult. The Blockchain Technology Application Innovation Competition is a technology-based competition and has high requirements for participants. They need to have solid professional knowledge and blockchain skills. To participate, you must have chain theoretical knowledge, technical practice, industry practice and other skills.

For example, through a knowledge contest to obtain accounting rights (that is, adding blocks to the blockchain), this knowledge contest can be based on Pu'er tea. Whoever answers the question first will get the accounting rights. "The blockchain is equivalent to this ledger, and the block is equivalent to a page of this ledger. The information carried in the block is the transaction content recorded on this page.

4. Area Blockchain Case | It’s hard to stand up to Peking University and be like a rat!

The story starts with the blockchain project. We know that many of the founders of blockchain capital have backgrounds in prestigious universities. This is even more true for Beijing, Qing, and top foreign universities. This is no accident. As far as I know, entrepreneurs or partners are much more diligent than you think. Of course, most of them have a good education background and will naturally pay attention to trends.
< br />But a small number of capitalists like to use their educational background to sugar-coat high-ranking officials.

Why? I believe you and I have not said it or it is difficult to say it.

Today Take the Hero Entertainment Chain, which has been widely infamous for air coins in the chain currency circle for more than half a year, as an example:

The Hero Chain public account has been suspended for more than a year.

"This year In May, CCTV News directly named the Hero Chain project, accusing it of committing false fraud in the name of tokens. As the sales director of Hero Chain, Peking University talent Liu Hongyuan became the target of public criticism after the incident.

After the incident, Liu Hongyuan fled to Singapore, and Hero Chain CEO Gao Zhun also led his team to Cambodia. "——The little monster next door.

What is the Hero Entertainment Chain? Who are the people on the platform?

"The Hero Chain (HEC) was launched in January this year and supports digital encryption. A currency gambling game platform, the project CEO is Micro Motion. ”

Hero Chain White Paper:

Who is Liu Hongyuan and how did he get involved in the Hero Chain?

Liu Hongyuan, former director of the Venture Capital Research Association of Peking University President. As an angel investor, Chen Manli has an educational background at Tsinghua University that can easily connect with college students. She took a fancy to Liu Hongyuan, who was anxious about starting a business.

"In addition to Liu Hongyuan, people who participated in proxy investment include Wang Dapao, Mr. Bai, Bit Wu, etc. These people have contributed to the sales of Hero Chain."

It can be seen from the white paper As of now, Hero Chain tokens are stipulated not to be circulated within one year and will be locked. Funds raised are used for development.

The manipulator behind the Hero Chain Entertainment Chain is actually Hash Capital Chen Manli.

So, who is Chen Manli?

She works in ten companies including Dream Peak Technology Co., Ltd., and holds senior management positions. There is also Tsinghua Macquarie Master of Applied Finance, which can connect university students as teachers.

Hash Capital where Chen Manli works - background introduction

Hash Capital is a digital asset investment research institution co-founded by Mr. Deng Deyan and Mr. Nick.Fu (Fu Xiaoming). The founder, Deng Deyan, holds a master's degree in applied finance from Tsinghua Macquarie. He was a foreign exchange analyst at a well-known Australian financial institution and has many years of experience in securities foreign exchange and spot trading. Mr. Fu holds double degrees in law from Renmin University of China and communications engineering from Wuhan University of Technology.

Hash Capital and Asia-Pacific Blockchain Business Applications

Hash Capital has raised 3 funds since its establishment, totaling tens of millions of dollars, focusing on the Asia-Pacific market Blockchain business applications and digital asset-related projects. The projects invested by Hash Capital have gradually formed a coverage of the entire blockchain industry chain, including smart contracts, securities transaction settlement, identity certification, distributed accounting, e-commerce, data API and blockchain infrastructure and other fields. Investments include IPTChain, KTrade, Loopring, Qcash, CoinMeet, Halal Chain, Nuls and many other high-quality digital assets.

Comments on mutually reinforcing each other:

Long titles are normal among project founders. After all, blockchain projects do not necessarily require an actual company, and a chocolate office like the Newton project is acceptable. How founders make themselves known to investors is a problem. Therefore, the founders of each project party will have separate titles. People who have experience leading projects are more likely to win the trust of investors.

Create a conversation that is not a joke:

"What do you have?"

"I have a Title."

This shows the importance of titles in the blockchain industry. Dialogue is dialogue, and the founders of the project are still very capable and have professional knowledge background.

From the perspective of covering the entire investment industry, it gives people a professional and grand feeling. It’s such a high-end-looking institution that hidesChen Manli is the manipulator behind the Hero Chain entertainment chain.

Being like a rat with Peking University on your back—difficult!

Why do Chen Manli and other small capitals like to station themselves in Gaofu and sugar-coat things? !

Peking University has administrative status and potential value in the consciousness of the Chinese people

When talking about Peking University, do you feel the same inexplicable heat in your chest as I do now? You have not received its blessings, but you seem to have received them. Surrounded by great benefits. I want to say more but I'm afraid I won't be able to say enough. Peking University Peking University adheres to the principle of freedom of thought and embraces inclusiveness. Probably because Peking University belongs to the Chinese people, not you and me.

1. Taking Peking University as an example, its administrative status makes it more than just an institution

.

Peking University once held the status of the capital, starting from the position when Peking University was founded. By definition, it is the only school established as the country’s highest institution of higher learning in modern China. Initially, it was also the country's highest educational administrative agency, exercising the functions of the Ministry of Education and overseeing national education.

It can be seen that the administrative functions of Peking University have historical origins.

Even if you and I don’t remember him for a moment, we think he is an ordinary student or teacher. But some things are really subtle, and many people and rural parents have a brand-like influence on their subconscious minds, just like the widely spread Nainai Temple.

2. Even if the Chinese people’s feelings about the Peking University and the Qing Dynasty are not deep, they are not shallow either

As a normal Chinese child when I was a child, I believe that everyone was the same. In childhood, I must have been instilled with different cultural backgrounds. But the same meaning was expressed in the eulogy of Peking University, Qingda University, Renmin University of China and other Beijing universities. It is undeniable that I also have feelings for Peking University and Qing Dynasty. These feelings are often for people because the great masters gave speeches at Peking University. I don’t have many impressions of Peking University, but it’s not shallow either. This influence was so great that when the top scholar in science in Sichuan Province wanted to describe himself as a three-dimensional person rather than a learning machine, he still chose to write "Peking University is my beautiful and shy dream". In human terms, it was for Peking University. As a PR person, I am well aware of the issue of Peking University’s status in the hearts of Chinese people.

Therefore, it is understandable that Peking University is uneasy at this moment.

She, Chen Manli, is still the same, with the same appearance, a teacher title on her head, and the Global University Blockchain Entrepreneurship Leaders Alliance (the launching ceremony of the Global University Blockchain Entrepreneurship Leaders Alliance is July 25 From 14:00 to 16:00 in the afternoon, the Blockchain Leaders Event (Blockchain Leadership Event) Consulting Mentors was held in Room 601, Building C, Mingde Building, Renmin University of China, No. 59 Zhongguancun Street, Haidian, Beijing, once again targeting students from Peking University and other universities.

If today’s entrepreneurial teachers and students hold Peking University’s back and want to be like shit, that’s hard!!!

Because of the rat shit in Beijing University, Liang Hongzhi, Shi Ping, Zhang Zongxiang, etc. Aren't they just ordinary people? !

If you ask whether Peking University has some management skillsSome of our old alumni are involved in blockchain, is it true?

The article has been abridged. For the full version, please go to the public account [OnlyTimeKnow] to reply to "I want to do rat shit on my back to Peking University."

5. What is the use of the blockchain competition for college students

Contestants do not need to be able to write code, they only need to understand blockchain technology Principle, understand the situation of integration with industry, and design new industrial blockchain applications with blockchain thinking, you will have a chance to win a grand prize of 20,000 yuan.

The competition is divided into two parts: "Proposition Competition" and "Free Competition". There are two opportunities to win bonuses. Excellent application designs have a chance to obtain investment and incubation, paving the way for entrepreneurship.

Blockchain technology plays an increasingly important role in the development of the digital economy and has huge development potential.

In order to support the development of blockchain technology, the "Hot Chainers First College Student Blockchain Application Design Competition" was officially launched!

This competition aims to spread blockchain technology so that it can attract more attention, let more people understand and become interested in the application of blockchain technology, and develop ideas for blockchain applications. , explore blockchain application scenarios, explore blockchain application projects, cultivate talents in China’s blockchain field, and cultivate a talent base for China to become the engine that leads the development of the world’s blockchain industry.

6. Zhong Hong, Director of Tsinghua X-lab Digital Economics Laboratory: Blockchain technology injects new vitality into the media industry

Currently, a new round of technological revolution is emerging around the world. Industrial transformation and digital revolution, blockchain, as a subversive technology of the Internet, is becoming an important technology for this round of technological revolution and industrial transformation. Information technology represented by blockchain is accelerating the networking, digitalization, intelligence and greening of the global economy, and is driving technological breakthroughs in related fields including biotechnology, new energy technology, new materials and other related fields.

“Especially in business scenarios related to education, law, government services, health care, targeted poverty alleviation, etc., blockchain has a very important innovative role and is becoming an important production tool in future society, and A new infrastructure for global digital civilization and data order in the digital era." Zhong Hong further gave an example.

As Tsinghua University is one of the earliest universities to research blockchain technology, Tsinghua x-lab has been promoting the cultivation and training of blockchain professionals three years ago. "In 2018, Tsinghua SEM The college led hundreds of universities across the country to jointly build a university without walls based on blockchain, allowing our teachers, students, and professional knowledge to create a comprehensive platform for knowledge sharing based on blockchain and new Internet platforms. Then last year In April 2019, Tsinghua x-lab and Guoyan Think Tank jointly established the Digital Economics Laboratory, focusing on the digital economy driven by the new generation of information technology and studying data as the core element.development model. " Zhong Hong said.

On April 30 this year, the Ministry of Education issued the "Blockchain Innovation Action Plan for Colleges and Universities". In this action plan, it was clearly proposed to lay out and construct in colleges and universities in 2025. A group of blockchain innovation bases have cultivated and gathered a group of blockchain technology research teams to promote universities to become important positions for blockchain technology innovation in my country. Against this background, Tsinghua x-lab and Tsinghua University Technology Innovation Center Adhere to technological innovation as the center and integrate and promote "blockchain + industrial center".

On September 19, initiated by the China Economic Media Association, China Times, etc., Tsinghua University Technology Innovation Research Center, etc. Providing academic support, the media blockchain industry think tank jointly built by Huolian Research Institute and others was officially established. “We not only promote technology research, but also promote the integration of blockchain technology and the media industry as a national think tank, driving the media industry and blockchain In-depth integration of chain technology. "Zhong Hong said.

7. Blockchain may be the best opportunity for young people to make a comeback

Xingchen | 7.14 work notes

Hello everyone, I It's Xingchen, here, sync my work notes.

There is a joke in the industry: "Blockchain may be the best opportunity for young people to make a comeback."

Zone In the early stages of blockchain industry development, there are relatively large investment opportunities, and this industry attracts capital and hot money. No one can refuse such an industry with high return potential.

In the early years, District Blockchain or currency speculation, players are all high net worth, highly educated, and highly risk resistant. It is a game for a few people.

Although everyone knows it now, most people still know it Fuzzy, judging from the current policy, it is not conducive to the development of the industry if everyone participates regardless of you and me. The huge pit of the new industry will only swallow up the swaying passers-by.

In the industry , I have come into contact with more and more practitioners, and my great feeling is that the future belongs to young people.

They are more open, more energetic and more innovative.
< br />Look, Vitalik Buterin was only born in 1994.

A netizen who asked me about mining machines before accidentally mentioned yesterday that his child is studying at UBC in Canada and is a blockchain engineer. In the direction of the chain, I am planning to buy some mining machines to "pay some" tuition for my children.

I checked and found that starting in 2016, domestic universities have also begun to offer blockchain courses, but most of them are still based on Mainly general courses.

Although this is the case, it is enough to make people enviable. At least I am very envious. In a stage of life full of unknowns, there is such a pure learning atmosphere and I can come into contact with the most beautiful people in the world. Cutting edge technology.

I also heard that some universities even have blockchain societies that take the lead in building alliance chains, co-building university nodes, establishing scientific research mining pools, and building blockchain network laboratories.

Speaking of this, I have to recommend a university blockchain technology community:

This is composed of Tsinghua University, Peking University, Central Finance, National People’s Congress, Hong Kong University of Science and Technology, Nankai University, Shanghai Jiao Tong University, A Chinese university blockchain technology community jointly launched by the heads of the top 20 university blockchain associations such as Fudan University, Zhejiang University, Sichuan University, Wuhan University, and Huake University.

This is a gathering of domestic students who love blockchain technology.

I browsed the content of this community and added the initiator’s WeChat account. I found that it was quite active and felt their intentions.

This community gives priority to students and requires a student ID photo to prove student identity. I recommend this community to my clients and friends.

This is a customer who had Chia P plate done at my place in May this year. He is a sophomore.

Due to academic reasons, we have never met each other, and because the business involves a lot of money, his mother flew from Shenzhen to Hangzhou to meet me. She is an enlightened mother, gentle and elegant in conversation. , pay attention to details, act rigorously, support children to contact and practice new things, and participate in them themselves.

Although the Chia project is not a successful investment at present, I still believe that there will be some costs on the way to learning and growth. The young power he represents will change the industry. More interesting.

Blockchain is not the best opportunity for all young people, but the best opportunity for young people who love blockchain.

In the field of blockchain, in addition to young people pursuing profits, there will also be a large number of young people chasing the technological wave and creating a new world.

This youth not only refers to age, but more to the heart that is always young and always embraces new things.

Good night, young friends.

8. FISCO - Golden Chain Alliance creates a new era of public alliance chain

Public chain, alliance chain (permission chain) and private chain can be said to basically include blockchain technology Three ways to use it. 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 belong to respective companies and institutions.We built our own internally operated blockchain architecture and disclosed very little information, but we believe that using our own money to do our own things and solve our own problems will not cause any major problems.

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 Exchange. 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 technology research resources, form a synergy and coordination mechanism for financial blockchain technology research and application research, and 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, as well as 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 a strong reputation in credit and stock markets.Research directions have been set up in the fields of rights, points, insurance, bills, cloud services, digital assets, financial product issuance and trading, and some projects have now been implemented or product prototypes have been launched.

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 security 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 are also certain issues of mutual trust, collaboration or cooperation reciprocity.

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.

Blockchain technology as aA combined infrastructure solution that 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 AMOP (Advanced Messenger On-chain Protocol), focusing on the following functions:

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

 Provides standardized interfaces for the interaction between off-chain systems and blockchain;
< br />  The blockchain system can actively call the business interface of the off-chain system;

The technical characteristics of this protocol are:

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

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

 In communication Encryption technology is used in the process to ensureCommunication layer privacy.

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.

Special Prize: ODRchain - a typical application of public consortium chain

The most high-profile champion project - ODRChain, is based on the FISCO BCOS underlying platform and 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 turns your phone into a USB shield

The project that grabbed the first prize in the competition - JustSign, is an electronic contract signing and certificate storage system based on FISCO BOCS. Its original JustKey white-box password algorithm realizes "the mobile phone is a USB shield" and solves the problem of traditional CA compatibility. There are problems such as limitations, inability to protect key security on the mobile terminal, and centralized data storage being vulnerable to attacks.

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 entered 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, team representatives 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.

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.

9. What does the blockchain competition do?

New application models of computer technology such as data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc.

It is the simplest application scenario of blockchain. It itself needs to maintain the data consistency of each node. It can be said to have its own information sharing function.

Blockchain

From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

10. Female scientist Duan Sisi: Fighting with each other behind the blockchain "jianghu"

Duan Sisi works as a researcher at the Institute for Advanced Study at Tsinghua University. There are very few things in her working place, and the equipment is only three computers. The strange and dangerous offensive and defensive advances and retreats are only brewed in the mind and deduced on the keyboard, and there is no "smoke of gunpowder".Mark of.

Her research direction is "Byzantine Fault Tolerance Algorithm", which aims to prevent network collapse caused by "enemy destruction" of each node in a distributed system. To put it figuratively, she is engaged in a high-intelligence "hands-on-hand game." The first step is to imagine a possible loophole or "enemy"; the second step is to find a way to make the "enemy" ineffective; the third step is to convince peers that she is solving a "real problem".

Duan Sisi defines himself this way: between a scientist and an engineer. She does not directly "fight" with hackers like a network engineer. She uses the power of mathematics and logic to set rules that make the "enemy" powerless.

"There are bandits among us." Duan Sisi used the term "killing game" to compare the "Byzantine Generals Problem" she studied. "The bandits spread false news and mislead the good people's judgment, and the war will be lost. What I want to do is to formulate an agreement to ensure that even if there are bandits, the good people will not lose."

Eighth century When the “Byzantine Generals Problem” was proposed in the early 1900s, no one knew what blockchain was. It is the continuous pragmatic research on this issue that supports today’s blockchain technology. Now, China has regarded blockchain as an important breakthrough for independent innovation in core technologies.

At first, the direction Duan Sisi chose was a bit unpopular. People who didn’t know what she was doing thought she was solving Mathematical Olympiad problems. She also encountered rejections from scientific journals. After the rise of blockchain, people saw the importance of network security protocols, and her academic achievements were seen by more people.

In January this year, Duan Sisi was selected as one of the "35 Technological Innovators Under 35 Years Old" in China in 2021 by MIT Technology Review. The reason for the award is that she proposed multiple industry-leading Byzantine fault-tolerant protocols. , achieved outstanding results in the fields of distributed systems, blockchain and applied cryptography.

Riding the fast train of emerging technologies, Duan Sisi said that he was quite lucky, but the explanatory power of luck is limited after all. There were not many female classmates during her master's and doctoral studies, and most of them did not continue their academic careers. The reason that supports her in not giving up is "it's quite interesting."

What makes Duan Sisi interesting is the various tricky questions she has come up with. In her opinion, discovering problems is sometimes more important than finding answers.

“Sybil attack”, “hard fork”, “Merkle tree”, “asymmetric encryption”… When asked to popularize these “black words” in the blockchain circle, Duan Sisi was like: When you press the answering machine during a quiz show, you think quickly, speak quickly, and explain the questions quickly.

Duan Sisi studied in the Department of Electrical and Electronic Engineering at the University of Hong Kong. He received his PhD in Computer Science from the University of California, Davis, in 2014. After graduation, he worked at the Oak Ridge National Laboratory and the University of Maryland. The whole family will return to China in 2020.

"I feel that domestic development is fast and the pace of work is also fast. I am more eager to develop in this aspect, especially in the computer field, although it will be tiring." She said.

Young and promising, with an interesting career and a happy family, people around her say she is a "winner in life", but she thinks her life is "a piece of cake". She is the mother of two boys, aged 6 and 4. She once held her baby in one hand and wrote code with the other.

She refuses to give up when she is young and can’t stop doing what she wants to do. This is also reflected in her work style. "Others can write code piecemeal, but I am used to writing it in one go."

To solve a Duan Sisi-type problem requires writing tens of thousands of lines of code, which takes at least several months of work. What this "scientist with a baby" desires most now is a chunk of time. "Once you are interrupted, you will forget what you were thinking when you come back," she said.

Duan Sisi shared an experience about "time management": If you encounter something that can be solved within 5 minutes, then solve it now. It will definitely take more than 5 minutes to put it off later.
