『一』How to solve blockchain security issues

One of the characteristics of blockchain projects (especially public chains) is open source. Open source code improves the credibility of the project and allows more people to participate. But the openness of source code also makes it easier for attackers to attack the blockchain system. There have been many hacker attacks in the past two years. Recently, the anonymous currency Verge (XVG) has been attacked again. The attacker has locked a vulnerability in the XVG code, which allows malicious miners to add false times to blocks. After stamping, new blocks were quickly mined, and nearly US$1.75 million worth of digital currency was obtained in just a few hours. Although the attack was successfully stopped, no one can guarantee whether the attacker will attack again in the future.
Of course, blockchain developers can also take some measures
The first is to use professional code audit services,
The second is to understand safe coding standards and nip problems in the bud.
Security of cryptographic algorithms
The development of quantum computers will bring major security threats to the cryptographic systems currently used. Blockchain mainly relies on the elliptic curve public key encryption algorithm to generate digital signatures for secure transactions. Currently, the most commonly used ECDSA, RSA, DSA, etc. cannot withstand quantum attacks in theory, and there will be greater risks. More and more Researchers are beginning to focus on cryptographic algorithms that are resistant to quantum attacks.
Of course, in addition to changing the algorithm, there is another way to improve security:
Refer to Bitcoin's handling of public key addresses to reduce the potential risks caused by public key leaks. As a user, especially a Bitcoin user, the balance after each transaction is stored in a new address to ensure that the public key of the address where Bitcoin funds are stored is not leaked.
Security of consensus mechanism
The current consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS). , Practical Byzantine Fault Tolerance (PBFT), etc.
PoW faces 51% attack problem. Since PoW relies on computing power, when an attacker has a computing power advantage, the probability of finding a new block will be greater than that of other nodes. At this time, it has the ability to undo transactions that have already occurred. It should be noted that even in this case, the attacker can only modify his own transactions and not the transactions of other users (the attacker does not have the private keys of other users).
In PoS, an attacker can only successfully attack when he holds more than 51% of the token amount, which is more difficult than 51% of the computing power in PoW.
In PBFT, malicious nodes are smaller thanThe system is safe when the total number of nodes is 1/3. In general, any consensus mechanism has its conditions for establishment. As an attacker, you also need to consider that once the attack is successful, the value of the system will be reduced to zero. At this time, the attacker has nothing to do except destroy it. Get other valuable rewards.
For designers of blockchain projects, they should understand the advantages and disadvantages of each consensus mechanism, so as to choose an appropriate consensus mechanism or design a new consensus mechanism according to the needs of the scenario.
Security of smart contracts
Smart contracts have the advantages of low running costs and low risks of human intervention. However, if there are problems with the design of smart contracts, it may cause greater losses. In June 2016, The DAO, Ethereum's most crowdfunded project, was attacked. Hackers obtained more than 3.5 million Ethereum coins, which later caused Ethereum to fork into ETH and ETC.
The measures proposed in this regard have two aspects:
The first is to conduct security audits of smart contracts,
The second is to follow the principles of safe development of smart contracts.
The security development principles of smart contracts include: be prepared for possible errors and ensure that the code can correctly handle bugs and vulnerabilities; release smart contracts with caution, do functional testing and security testing, and fully consider boundaries; maintain The simplicity of smart contracts; pay attention to blockchain threat intelligence and check for updates in a timely manner; be clear about the characteristics of blockchain, such as cautiously calling external contracts, etc.
Security of digital wallets
Digital wallets mainly have three security risks: First, design flaws. At the end of 2014, a serious random number problem (duplication of R values) caused users to lose hundreds of digital assets in a certain lottery. Second, digital wallets contain malicious code. Third, lost assets caused by loss or damage of computers and mobile phones.
There are four main countermeasures:
The first is to ensure the randomness of the private key;
The second is to verify the hash value before installing the software to ensure that the digital wallet software has not been tampered with ;
The third is to use a cold wallet;
The fourth is to back up the private key.

『二』 Four core issues need to be solved for the implementation of blockchain. Interview with Chen Wei, President of Bank of Communications Investment Banking Center

As the concept of blockchain continues to heat up and this technology is becoming increasingly mature, financial institutions including banks are also increasing their deployment and application in this field. The "Archaean - 2019 China Blockchain Financial Industry Research Report" points out that financial institutions' investment in blockchain is growing year by year. It is expected that by 2022, China's financial institutions' investment in blockchain technology will reach 9.27 billion yuan.

Chen Wei pointed out that the essence of asset securitization business is to replace the subject credit with asset credit, and with the help of blockchain technology, technological mutual trust can be achieved to replace institutional mutual trust. These two points make blockchain technology suitable The needs of asset securitization business scenarios. Based on this, Bank of Communications launched China’s first blockchain asset securitizationPlatform - "Chain Fusion". Chen Wei also said that blockchain technology will also play a positive role in promoting Shanghai's "Yangtze River Delta integration" and building an international asset management center.

The "efficiency + trust" problem needs to be solved

"China Business News": Although many banks have explored and researched blockchain, there have been few projects that have been implemented in the end. What do you think is the reason why blockchain technology is difficult to implement?

Chen Wei: Since blockchain mainly uses alliance chain technology, banks mainly face the following four problems when exploring the application of blockchain technology in specific business implementation:

The first one is safety. Commercial banks are important participants in the infrastructure construction of the entire financial system and have particularly high requirements for reliability and security. In the application of new technologies, safety requirements are the most important and must be met. Since the application of blockchain technology is still in the exploratory stage, this may affect the implementation of blockchain technology in specific businesses.

The second is efficiency. In a decentralized setting, all nodes need to reach a consensus and process the data, which takes a lot of time. Therefore, it is currently difficult to effectively balance business efficiency. Some traditional businesses of banks, such as payment, transfer, remittance and other business scenarios, have high requirements on time efficiency and data storage. Therefore, there are still certain difficulties in integrating blockchain technology with these business scenarios.

The third is cross-agency consensus. The alliance chain requires all parties in the alliance to reach an agreement and jointly promote the formation and expansion of the chain. However, in the actual business promotion process, different institutions have great differences in their understanding of the blockchain and their needs for the alliance chain, and there is a certain degree of difficulty in coordination and promotion. .

The fourth is economic cost. Blockchain applications require high technical development capabilities of banks and require a large amount of software and hardware resources. For example, alliance chains need to deploy nodes and form consensus algorithms and a series of services; banks need to invest a lot of human and financial resources in development. These inputs may not directly produce visible economic profits in the short term, and there will be an intertemporal mismatch of costs and benefits. Any financial institution, whether listed or not, will face the problem of current assessment, which creates a certain contradiction between the current nature of costs and the lag of income.

Of course, despite the existence of these four main contradictions, many banks are crossing the river by feeling the stones and constantly exploring. It can be said that in this regard, Bank of Communications has actively responded to the national call and is at the forefront of the industry in the application of blockchain technology, especially in the field of asset securitization, achieving many breakthroughs.

Chen Wei: The so-called efficiency is a matter of time, and trust is a matter of safety.

Regarding the efficiency issue, combined with the exploration and practice of Bank of Communications, it can be solved in the following three ways: first, through the automation of smart contracts on the chain, to improve the efficiency of business processes; second, , researching high-performance public chainstechnology to meet the computing and storage capabilities in the case of concurrent transactions; third, with the help of cloud computing, the storage capabilities of the cloud can be used to improve efficiency and reduce economic costs.

Regarding the issue of trust, there are three main ways to solve it: First, reach a consensus before going on the chain. Participants must sign an agreement to express their agreement before going on the chain to avoid problems due to failure to reach a consensus during the business development process. This leads to reduced efficiency and difficulty in implementation; secondly, digital signature and asymmetric encryption technology are used to encrypt the data before uploading it to the chain to ensure that only authorized parties can see the data and achieve control of data permissions; thirdly, Blockchain technology uses distributed ledgers to ensure that data cannot be tampered with and can also be traced to ensure that all participants maintain a high degree of trust in the data on the chain.

Promoting the "integration" of assets and funds in the Yangtze River Delta

"China Business News": What are the characteristics and highlights of Bank of Communications in exploring blockchain scenarios?

Chen Wei: There are many discussions about blockchain usage scenarios in the current market. In terms of blockchain empowering finance, asset securitization business is one of the most suitable scenarios. Based on its practical exploration and first-mover advantage in the asset securitization market, Bank of Communications has been trying to explore the application of blockchain in asset securitization business scenarios since 2016, and officially released the first domestic blockchain asset securitization in 2018. Platform - "Chain Fusion". The platform has obtained two technology patents - "A cross-agency process solution based on smart contracts" and "Fabric blockchain management solution based on smart contracts", and won the 2018 Shanghai Financial Innovation Achievement Award issued by the Shanghai Municipal Government. Award, "China Banker" Top Ten Blockchain Application Innovation Award and other awards.

There are many participating institutions in the asset securitization business, the issuance cycle is long, and the transaction structure is also relatively complex. How to carry out the business more efficiently requires solving the problem of information asymmetry. Blockchain technology has the four characteristics of decentralization, transparency, sharing, and non-tampering, which means that blockchain technology can achieve a perfect combination with asset securitization.

From the perspective of the business itself, the essence of asset securitization business is to replace subject credit with asset credit; at the same time, with the help of blockchain technology, technological mutual trust can be achieved to replace institutional mutual trust. These two points make the blockchain Chain technology and asset securitization business can fit perfectly. Blockchain technology can make all data information in the system open, transparent, non-tamperable, and non-forgery without the need for third-party endorsement, and it can also trace the information.

"China Business News": In practice, how does blockchain technology empower asset securitization business?

Chen Wei: On the "Chain Fusion" platform, with the help of blockchain technology, underlying assets and due diligence reports and other information are permanently stored on the chain through digital fingerprints. With the help of the transparency and transparency of the blockchain, Features such as sharing and non-tampering solve the problem of asset securitiesIt solves the problem of mutual trust among many participants in the business and achieves credit penetration; it uses some algorithms to achieve encryption protection of files on the chain, effectively mitigating the risk of information leakage.

At the same time, the application of blockchain technology also reduces some maintenance costs and system operation pressure. Since the issuance of Asia’s first blockchain technology-enabled credit asset securitization project, “Jiaoying 2018 First Phase Personal Housing Mortgage Asset-Backed Securities,” Bank of Communications has issued approximately seven or eight Projects worth tens of billions of yuan. We have also been committed to promoting more high-quality originating institutions, professional investors and other asset securitization ecosystem users such as Guodian Electric Power to join the chain.

"Chain Fusion" is the incubation result of the "Financial Innovation Joint Laboratory" and the product of the joint linkage between the front, middle and back offices of Bank of Communications. In the early stage of research and development, the business department took the lead in the entire project based on market sensitivity, and the middle and back-end departments collaborated. After blockchain technology is put into use, we continue to keep pace with the times and iteratively upgrade the system.

In addition to the internal collaboration of Bank of Communications for research and development, Bank of Communications also took the lead in establishing the asset securitization business ecosystem - the "Lujiazui Asset Securitization Alliance", and through cooperation with peer institutions, jointly cultivate and Developing the ecosystem system is also a manifestation of Bank of Communications' social responsibility and realization of social value.

"China Business News": In addition to empowering banks' specific businesses, what help can blockchain technology provide to banks in participating in the "Yangtze River Delta Integration" and serving Shanghai in building an international asset management center?

Chen Wei: The application of blockchain technology in asset securitization business scenarios actually shortens the information distance between asset holders and fund holders, and also breaks the boundaries of administrative divisions. With the help of blockchain technology, various participants in the "Chain Fusion" platform reach asset consensus and price consensus. For example, assets in Shanghai can be connected to funds in Jiangsu, which to some extent promotes the development of assets in the Yangtze River Delta region. and the “in-city integration” of funds.

At the same time, blockchain technology can also provide certain help to Shanghai in building an international asset management center. Building an international asset management center means attracting a large amount of overseas funds or fund management institutions to Shanghai. Only by providing a wealth of high-quality assets to choose from can overseas funds or institutions be retained. The asset securitization business has developed relatively maturely and has a large scale in the international market. In contrast, the asset securitization business is still in the development stage in China. As China continues to open up to the outside world, more and more foreign capital will enter China to invest in some high-quality domestic assets in the future, and the "chain integration" platform may play a more important role.

Generally speaking, blockchain technology is closely related to strategic issues such as Shanghai’s Yangtze River Delta integration construction, free trade zone construction, and the construction of a global financial technology center and asset management center, and will also Make new contributions to serve the national strategygreater contribution.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the only "blockchain technology" approved by the "Smart Learning Workshop 2020- Xueshuo Innovation Workstation" carried out by the School Planning and Construction Development Center of the Ministry of Education of China. Professional” pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

『四』What challenges does my country’s blockchain development face?

At present, the development status of my country’s blockchain technology is that there are many patents, few papers and few codes, no independent secure and controllable underlying platform, and no The integrated platform of software and hardware will directly lead to the technical risk of the core technology of the blockchain being controlled by others, the financial risk of foreign open source platforms seizing the financial market, and the economic risk of foreign open source platforms penetrating our country's real and virtual economy. Therefore, it is very important to implement blockchain applications as soon as possible. Now various places have implemented applications with policy support. Changsha High-tech Zone has officially implemented a blockchain project, called SMIC Blockchain Service Platform, which is a The government-enterprise service platform, in cooperation with Changsha Bank, Dean Judicial Services, etc., is now in the stage of recruiting companies to join the chain.

『Wu』3 suggestions on the blockchain field

Including emerging industries such as blockchain, in the early stages of development, there is a market for operations and fraud, and the scale is indeed Very big

On the other hand, we can see that in information tools, especially in the emerging defi protocol, defi protocol attackers are well prepared, not only for exploiting protocol vulnerabilities, but also for After the transfer of cross-chain assets, the use of mixed currency services, a series of operations, and general attacks, funds were cleared within half an hour. thisA huge challenge for regulations

Especially when there are no automated tools to help with analysis, preventing attacks becomes very difficult

Back to the question. I suggest, if you are really interested in this field, first of all, don't invest your life. Make more relevant supervision and adjustments based on the amount of loss you can afford. Don't trust so-called experts, insiders, inside information and high rates of return. Try not to believe this information

I hope you will respect common sense. When you notice a high rate of return on your investment, people will see your capital. They are ultimately deceiving or attacking people's greedy mentality

If something like this unfortunately happens, we should do our best to interact with the community as soon as possible to discover and expose the problem. Leverage the power of the community to find better channels to report crimes to the police and pursue accountability with the power of justice. Network Security Issues

From the promulgation of my country’s “Cybersecurity Law” to the previous Didi incident, they are all related to network security issues. If this issue is not handled well, it may affect the future development of the company and may involve administrative penalties or even criminal liability

2. Pay attention to data protection

Internet companies, especially Blockchain enterprises require a large amount of data storage and processing, desensitization and cleaning. Maybe this data will also involve some sensitive data. If this data is not handled properly, it will lead to data leakage. It will also generate legal liabilities, including civil, administrative and even criminal

3. In-depth supervision

Recently, we have found some companies in some legal services, because with the government As regulatory policies continue to strengthen, they may be engaged in some previous areas, such as mining and industries involving digital assets, which are not allowed to continue to exist in the country. Then some companies may wonder whether we can change our name or names to evade state supervision

However, we believe that the current supervision is a penetrating supervision. Not because your name has nothing to do with mining, digital assets, and state-restricted digital currencies, the state won’t police you. The country depends on what your business does

Therefore, for these three risks, our suggestions are:

1. In terms of network security, blockchain enterprises through the network Providing services and products, businesses are network operators. According to the relevant provisions of national laws, you shall bear the obligations and responsibilities imposed by the network operator's laws. Blockchain information services also have a filing system, which should be actively filed in accordance with legal regulations

2. In terms of data protection, our relevant laws and regulations are also very complete. Enterprises should strengthen data security protection when processing data, including the security of data storage. You can also use blocksThe anonymity and tamper-proof features of the chain

protect users’ data. Users’ explicit consent should be obtained during the use of data. Now the legal provisions are very clear, and users should be given the right to understand the purpose of data and delete data at any time

4. On issues of form and substance, we believe that regardless of business, traceability, certificate storage or application In any aspect, blockchain companies should serve infrastructure construction, my country's technological innovation and the real economy. Instead of using this technology to make money quickly

『Lu』Use the knowledge of economic life to explain the government How to further support and guide the development of blockchain technology

The development of blockchain technology itself is the result of the allocation of resources by the market economy. Therefore, the government still needs to give full play to the role of the market.

The government must strengthen scientific macro-control and comprehensively use economic and other means to support and guide the development of blockchain technology

The government must implement new development concepts and strengthen supply-side structural reform. Vigorously develop the real economy and promote the deep integration of big data, blockchain, etc. with the real economy. Create advanced manufacturing industry.

『撒』How to solve the problem of blockchain usage security

It needs to be mentioned here that the basic system structure of blockchain is as follows
① Network routing ② Crypto algorithm ③ Script system ③ Consensus mechanism
As for blockchain security issues, the script system is mainly completed by the script system. In blockchain technology, it is a relatively abstract concept. An extremely important function, in the blockchain, the formation of a valuable network relies on the script system, which is driven like an engine. The blockchain continuously sends and receives data. The so-called script refers to a set of rules. Confirm again that the rules for certain systems in the system are fixed. For example, in the Bitcoin system, only Bitcoin can be sent and received. Sending and receiving are done through Bitcoin scripts. The system allows users to program themselves. Once the rules are completed, they can be deployed into the blockchain ledger, so that the functions of the entire blockchain system can be expanded. For example, Ethereum realizes the functions of smart contracts through this set of customized script systems. Then specific scenario applications or real life cases such as order logistics information supply chain information.

『8』 How to apply blockchain technology to solve problems in supply chain finance

The essence of finance is value circulation. There are many types of financial products, including banks, securities, insurance, trusts, etc. The concept of traditional finance is a discipline that studies the circulation of monetary funds. The essence of modern finance is the capitalization process of business activities. Blockchain finance, as the name suggests, is the application of blockchain technology in the financial field.
Since 1978, China’s financialThe system has evolved in the direction of marketization, standardization, diversification, and internationalization. China's financial system has increased rapidly in a non-linear manner, both in scale and complexity. Various banks, financial institutions, and financial sub-markets are closely related and intertwined. Traditional financial companies are accelerating transformation and innovation in an attempt to occupy the market. At the same time, various new financial institutions are emerging in large numbers. The financial industry is experiencing the financialization of real estate and non-bank institutions. New trends such as banking.
In bank transactions, banks generally conduct transactions through third-party trading institutions, which increases transaction costs and also limits the scale of transactions. In cross-border transactions, there are more transfer processes and lower efficiency. By applying blockchain to transactions in the financial field, you are not subject to these restrictions. At the same time, due to the non-tamperable and traceable nature of the blockchain, transaction records on the blockchain will be preserved, and the flow and whereabouts of funds can be traced, which can reduce transaction costs. Through "blockchain + finance", the blockchain as the underlying technology system can have a series of evidence chains. When conducting fund transactions and transfers, risk control can directly use the records on these chains to better track and control risks.
In the field of asset management, various types of equity, bills, and assets are managed by various trust institutions. Transaction costs are high and transaction vouchers are easily forged. Through the blockchain + finance model, assets are processed on the chain. Due to the decentralized nature of the blockchain, holders can directly initiate transactions without relying on a trust center, effectively reducing the intermediate links in transactions. Blockchain technology has effectively improved the efficiency and quality of financial services and created innovative financial products and service models.
The blockchain BAAB platform independently developed by Yuan Zhongrui Technology empowers the digital economy and digital government, promotes the digital transformation and upgrading of various industries, and is committed to building a trusted infrastructure and application ecosystem in the digital era. At present, the financial industry is developing at a rapid pace. Blockchain has shown great potential in innovation and reform in the financial industry. It is bound to develop into a core technology for the development of the financial industry and create a new ecosystem for the industry.

『九』 What are the issues that need to be improved in blockchain applications

2018 is the first year of blockchain, but the world’s overall blockchain industry is still in its infancy, except for the financial industry. The maturity of the blockchain industry requires the integration of a series of factors such as technology, market, supervision, and popularity. According to the current development momentum of the blockchain, experts predict that large-scale implementation can be achieved within 3 to 5 years, and the real economy will also have a new development model. .What are the issues that need to be improved in the application of blockchain?

Accelerating the implementation of blockchain technology in industrial scenarios still needs to focus on

1. Quick matching of application scenarios.

Use Blockchain technology can effectively solve the pain points of the industry market. In the mainstream B2B transaction mode scenario of the market, it is easier to combine using blockchain technology. If the application scenario meets the conditions of high transaction frequency, fixed transaction scope, insufficient credit, etc., blockchain technology can be easily implemented This scenario. In the future, as the foundation of blockchain technology matures, it will gradually be applied to moreTransaction model.

2. Further improvement of technology.

Blockchain technology is currently insufficiently complete, with 51% computing power attack issues, double-spend gap issues, high transaction costs, and TPS throughput Small volume, transaction block chain selection issues, excessive energy consumption by the POW consensus mechanism, hacker intrusions and other technical obstacles.

3. The industry mechanism is sound.

Accurately distinguish between centralization and decentralization. Decentralized relationship. Decentralization means that the entire operating system can operate autonomously under the condition that there is no central organization management. Under the conditions of decentralization, two strangers can realize trust quickly and at low cost, realizing Transaction facts. However, what is clear is that the ecosystem is not unmanaged. The blockchain is still the information center and requires constant technical efforts and repeated upgrades. There is a certain centralized mechanism behind it.

『 Shi』 The blockchain industry is ushering in a new market trend. What are the bottlenecks in the development of the blockchain industry?

Blockchain technology is a new distributed infrastructure and computing paradigm that can achieve Sharing, replication and authorization of distributed ledgers. It has the characteristics of multi-point consensus and is difficult to tamper with. It solves the problem of how to enable cross-institutional trust transactions in commercial networks, connecting all parties involved in financial services, and brings challenges of breaking down data silos and improving data quality. It has the potential advantages of security and lower transaction costs. Enhance risk control capabilities and have broad application prospects in the financial field. The blockchain industry is ushering in a new market trend, and there are some bottlenecks in the development of the blockchain industry. Only by breaking through these bottlenecks can we usher in the spring of blockchain. bring better development.

Finally, the development of blockchain technology will bring certain network security issues. We must pay attention to and solve information security and network security issues. Blockchain technology is not inherently secure. Any software system inevitably has defects and vulnerabilities, and will face attacks from the Internet. Poorly designed and poorly managed blockchain systems can be vulnerable to attack. In applications in the financial industry, data is an asset, so we should have a comprehensive understanding of the security of the blockchain, and first put security design and self-control first to avoid the occurrence of Bitcoin theft.
