㈠What are the shortcomings of blockchain technology?

At present, blockchain technology still has low performance, low transaction frequency per unit time, and technical problems in practical applications. There are many problems such as the lack of application ecological environment, insufficient relevant application cases, and the rampant scammers under the guise of blockchain.

㈡ The main problems in the current development of blockchain technology

Currently, blockchain technology is still in a very early stage. Not only has it not yet formed a unified technical standard, but also various technical solutions Still developing rapidly. However, in the past, it was thought that systems based on blockchain technology would be very resource-consuming (similar to Bitcoin), or that blockchain technology systems would have limitations in processing data, and other problems have already achieved technological breakthroughs. However, the scalability of blockchain technology has not been tested in large-scale practice, and it is still mainly in the prototype design stage. In addition, the blockchain industry is extremely short of talent. If you want to learn about blockchain, you can go to Lianbo. A large amount of blockchain information is updated every day. There are also blockchain technology training and blockchain-related activities. If you are interested, you can go and check it out.

㈢ What problems currently exist in the Ethereum blockchain ETH

The Ethereum blockchain currently exposes three major problems. For a long time, its founder Vitalik
Buterin has been Unable to interpret. The first is the overall low performance and TPS of the Ethereum blockchain; the second is the lack of isolation of resources. The CryptoKitties virtual cat incident once occupied
20%
of the entire Ethereum traffic, directly causing The inability of Ethereum network users to carry out timely transactions is the biggest pain point of non-isolation of resources; the third problem lies in the reflection of Ethereum’s governance structure. Blockchain is a decentralized distributed ledger. In the past, the founder team of Ethereum The overly centralized governance model that has dominated the development of its network has led to the current forks of Ethereum such as ETH, ETC, and ETF, and the Ethereum community is currently in a state of fragmented governance. In the view of "aelf" founder and CEO Ma Haobo, the various shortcomings currently occurring in the Ethereum network are unacceptable. Therefore, the positioning of "aelf" was born to benchmark the next generation of decentralized underlying computing platform of Ethereum, focusing on solving the current problems of insufficient performance, lack of resource isolation, and governance structure of Ethereum.

㈣ What are the existing problems of blockchain technology

1. Performance issues

Volume issues

Blockchain’s impact on data Backup requirements pose storage space challenges. Blockchain requires that after a transaction is completed, it is broadcast to the entire network, and every node in the system must back up data.

Take Bitcoin as an example. The block data since the creation block has exceeded 60GB, and the amount of blockchain data is still increasing. This will bring problems to the operation of the Bitcoin Core client. A big challenge.

Processing speed issues

The Bitcoin blockchain currently processes a maximum of 6.67 transactions per second, and a confirmation time is about 10 minutes, which can easily cause congestion delays for a large number of transactions, which may cause Limit applications with multiple small-amount transactions and highly time-sensitive transactions.

Although there are some methods to overcome it, methods to comprehensively solve transaction efficiency still need to be discovered.

Energy consumption is too high

Thirdly, the computing power in the mining process does not produce additional actual social value, and also wastes a large amount of electronic resources. With the increasing popularity of currency, blockchain has gradually become a capital-intensive industry with high energy consumption.

2. Centralization problem

Inequality of nodes

First, in theory, every node in the distributed network should be treated equally , but in order to obtain rewards for mining, each node may increase its computing power to compete for hardware, resulting in node inequality and destroying the randomness of blockchain accounting rights.

Industrialized and large-scale mining has given rise to mining pools

Theoretically, if the mining pools collude to control more than 51% of the computing power for system supply, a dual Although the costs of payment far exceed the benefits in the actual process, the possibility of collusive supply cannot be denied.

3. Privacy and security issues

Private keys are easily stolen

First, the current blockchain uses an asymmetric key mechanism. It has high security, but the private key is stored locally and can be easily stolen by hackers.

The transparency of blockchain data can easily lead to privacy leaks

Every participant in the public chain can obtain a complete data backup, and the entire system is open and transparent. The currency protects privacy by isolating the connection between the transaction address and the holder’s true identity.

When the blockchain needs to carry more businesses, how nodes verify information and execute commands requires more consideration.

4. Upgrade and incentive issues

The number of participating nodes in the public chain is huge

Whether it is upgrading or fixing errors, the system cannot be shut down and centralized. , it may be necessary to consider relaxing the issue of decentralization.

There is a competitive game between each node

Requires the improvement of incentive compatibility mechanism, how to enable self-interested nodes in the decentralized system to spontaneously carry out block data verification And accounting work, and designing a reasonable penalty function to suppress irrational competition is another challenge faced by the blockchain.

㈤ What is the impact of blockchain on the world economy

In just a few years, blockchain has developed from the 1.0 era to the 3.0 era.The update of each "era" has brought changes to the world. The development of blockchain can be divided into three stages from blockchain era 1.0 to 3.0: peer-to-peer transactions, smart contracts and blockchain application ecology (Token Economy)
Blockchain 1.0 era: digital currency return rate is king

Blockchain 2.0 era: smart contracts provide infrastructure support for upper-layer application development

Blockchain 3.0: The subversion of business lies in its transformation of production relations

All obstacles to the development of human society are fundamentally caused by "mutual distrust", especially among various parties. economic and financial crisis. If humans can solve the problem of mutual trust, then humans will complete a very big leap.
The development of blockchain has gradually laid the foundation for this direction. Humanity is entering the era of "smart contracts". This is the process of upgrading human trust mechanisms. Once smart contracts are reached, human society will face a new major upgrade. , as each person is a value creator, the value he creates can be accurately recorded and rewarded accordingly. There will be less and less interference between everyone, and people are truly moving towards independence and equality. Human civilization has evolved from an "identity society" to a "contract society", and blockchain is expected to lead mankind to transition from a "contract society" to a "smart contract" society.
Although blockchain has moved out of the conceptual stage, the current status of blockchain technology development is that the underlying technology is not mature enough and the applicable scenarios are relatively limited. On the one hand, there is still room for optimization and improvement in core blockchain technologies such as consensus algorithms; on the other hand, the processing efficiency of blockchain is still difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms all originated from abroad. Domestic blockchain technology service providers must patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. time period, it can be said that the entire domestic trend is waiting for the emergence of a super-powerful blockchain project.

㈥ 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.

㈦ The blockchain industry is ushering in a new market trend. What bottlenecks exist in the development of the blockchain industry?

Blockchain technology is a new distributed infrastructure and computing paradigms that enable the 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 technologyIt's not inherently safe. 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.

㈧ 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 the ascendant stage except for the financial industry. The maturity of the 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. Blockchain What are the issues that need to be improved in chain applications?

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 more transaction models.

2. The technology is further improved.

Blockchain technology is currently perfect Insufficient strength, 51% computing power attack problem, double-spending gap problem, high transaction costs, low TPS throughput, transaction block chain selection problems, excessive energy consumption of the POW consensus mechanism, hacker intrusions and other technical obstacles.

3. The industry mechanism is sound.

Accurately distinguish the relationship between centralization and decentralization. Decentralization means that the entire operating system can operate autonomously under the condition that there is no central agency management. Two strangers Under decentralized conditions, individuals can achieve trust and realize transaction facts at low cost and quickly. However, what is clear is that the ecosystem is not unmanaged, and the blockchain is still the information center and requires constant technical support. , repeated upgrades, there is a certain centralized mechanism behind it.

㈨ What impact does blockchain have on the real economy

Blockchain has become a new highland for global technological competition. Technology applications extend to many areas of the real economy. Actively promoting the deep integration of blockchain and the real economy will help promote my country's industrial upgrading and achieve the goal of high-quality development. Blockchain is a new model of open innovation, a new carrier for coordinating industrial integration and a new path to promote green development. It is in line with the five development concepts of "innovation, coordination, green, openness and sharing". Although blockchain has achieved "revolutionary" technological breakthroughs, there are still some problems and challenges in practical applications.
In the early days of the development of the blockchain industry, through "transactions on the chain", blockchain technology must realistically solve some ""Small problems" can specifically promote the development of the real economy from three aspects: reducing costs, improving efficiency, and creating an environment of integrity.
Blockchain will play the role of "reducing costs for the real economy."
Currently The real economy has high costs and thin profits, resulting in insufficient capital support for the real economy. Among operating costs, management costs and financial costs account for a large proportion, and blockchain technology can effectively help enterprises reduce the costs of these two parts.
Blockchain will play the role of "improving the collaborative efficiency of the industrial chain."
Enhancing industrial collaboration is an important way to promote China's manufacturing to the mid-to-high end. However, currently in many industries, the collaborative efficiency of the industrial chain is still not high. In the international This problem is particularly prominent in the trade field.
Blockchain will play the role of “building an honest industrial environment”.
Currently, the construction of my country’s social credit system is accelerating, but in some cases, partners cannot establish trust The process is still slow, and it is difficult to obtain various types of credit information. It is difficult for small, medium and micro enterprises to obtain credit loans from financial institutions. Through "transaction on-chain", all parties can more easily query the accurate historical credit status of the counterparty. Cooperation mechanisms can be established faster; banks can also more securely grant credit to enterprises based on transaction records, and help solve the problems of "financing difficulties, expensive financing, and slow financing" for small, medium and micro enterprises that operate with integrity.
Blockchain: A new model of open innovation
Blockchain is a decentralized, distributed database system participated by each node. It can be understood as a public accounting mechanism (technical solution). Its basic idea Yes: By establishing a set of public ledgers on the Internet, all users in the network jointly record and verify accounts on the ledgers to ensure the authenticity and non-tamperability of information. It is called "blockchain" because It uses a series of data blocks generated by cryptographic methods. Each data block contains all transaction information in the past period of time to verify the validity of its information and generate the next block. Complete and reliable Traceability, decentralization and decreditation are the three major characteristics of blockchain technology, which give it great potential for application in the financial industry and become the core technology of financial technology. With the emergence of virtual cryptocurrencies represented by Bitcoin Continuously being hyped by the market, blockchain technology has attracted great attention from all walks of life. Although virtual cryptocurrencies such as Bitcoin are currently relatively mature applications of blockchain technology, it must be pointed out that virtual cryptocurrencies are not exclusive to blockchain. The only application. The essence of blockchain is to decentralize, which is exactly the development trend of the future market.

㈩ The challenges currently faced by the blockchain includeWhich

What are the challenges that blockchain is currently facing
At this stage, application projects in the blockchain field are mainly divided into two aspects: First, new businesses that are more compatible with blockchain technology models, such as cross-border payment, supply chain finance, product traceability and other scenarios; the second is the application of reform based on existing centralized business, that is, using the economic incentive mechanism of Token.
With the development of technology, the number of application projects in this field is expanding rapidly. Many people believe that 2018 will be the year when blockchain will truly integrate with the real economy and explode. However, blockchain technology is still in its early development stage and faces challenges including the regulatory environment, lack of talent, and technical awareness.

From a technical perspective, applying blockchain technology to actual industry scenarios requires solving issues such as transaction speed, data consensus, and node maintenance. The current Bitcoin network can only process seven transactions per second, and the leading Hyperledger technology can only reach the level of 200 to 300 transactions; compared with the centralized system that can process tens of thousands of transactions per second, there is still a gap. Large distances. In addition, the current lack of relevant incentive mechanisms in the field makes it difficult for participating nodes to operate in an orderly manner. From a regulatory perspective, although most countries are actively embracing blockchain technology, there are currently no relatively complete regulatory regulations and industry standards. Inappropriate regulatory measures may hinder the innovative development of such emerging technologies.
Affected by various factors such as the underlying technology that needs to be further matured, the lack of smart contract public chain platforms, the lack of ecological compatibility of various Tokens, and unclear government supervision; at this stage, the implementation of blockchain application projects is relatively slow. It shows that the quality of projects varies greatly. For this reason, analysts said that compared with general-purpose blockchains, what will achieve breakthroughs in the short term may be focused blockchains for specific scenarios and applications.
