Ⅰ What problems currently exist in the Ethereum blockchain ETH
The Ethereum blockchain currently exposes three major problems, and its founder Vitalik Buterin has been unable to interpret them for a long time. . 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, which directly caused the Ethereum network users to be unable to carry out timely operations. Transactions are the biggest pain point of not isolating resources; the third problem lies in the governance structure of Ethereum. As a decentralized distributed ledger, the blockchain has been too central in the past. The founder team has dominated the development of its network. The centralized governance model has led to the emergence of ETH, ETC, ETF and other forks in the current Ethereum, 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.
II What are the challenges in the application of blockchain technology in the Internet of Things
What are the challenges in the application of blockchain technology in the Internet of Things
Blockchain in the Internet of Things Challenges in networking include but are not limited to the following three points:
1. The deployment and implementation of blockchain are jointly participated by multiple nodes, but the storage and computing capabilities of IoT nodes have certain limitations. Therefore, the deployment of blockchain technology in IoT nodes, whether the blockchain architecture is hierarchical, and issues that need to be strengthened in existing blockchain technology all need to be taken into consideration.
2. The Internet of Things will be real-time, and the blockchain consensus mechanism generally has delay problems. Therefore, consensus delay may cause feedback delay and alarm delay, which cannot meet the needs of existing IoT applications and requires further technical improvements.
3. The current application of blockchain in the Internet is only carried out within a certain range and limited nodes. Once blockchain is applied to the Internet of Things, the number of nodes will increase exponentially, and its frequent relational data query requests will pose a very serious challenge to the existing chained data architecture.
In today's society, new technologies and industries are emerging around the world, and network technology is being transformed into productivity at an unprecedented speed. The development prospects of the Internet of Things are broad, but it faces many historical opportunities and challenges; the application of blockchain in the Internet of Things can, to a certain extent, solve the problems and new needs faced by the Internet of Things.
Ⅲ What are the problems faced by enterprises in applying blockchain
1. What exactly do you want to accomplish?
Look carefully at your requirements and ask Do you really need blockchain? Do you need the additional guarantees provided by the protocol provided by the blockchain, or do you just need a distributed dataLibrary?
2. How much do you trust your partners?
Untrusted business partners can seriously affect blockchain projects. Moreover, they may also affect the blockchain’s proof-of-work or proof-of-stake.
3. How public or open do you need to be?
Who needs to participate in your blockchain? There is a continuum between public blockchains and Bitcoin or Ethereum, The smallest, most carefully controlled blockchain. I can imagine some special purpose public blockchains, such as power microgrids. I can imagine blockchain in financial services serving only a small group of partners and being private in nature. A blockchain that only serves one organization may look like a blockchain, but it has no value.
4. What are your data integration issues?
The biggest issue facing enterprise blockchain may not be the protocol, but integrating all the data used by blockchain participants Legacy data formats and data structures. Healthcare blockchain is a good example. There are hundreds of medical record formats in use, and any medical blockchain will have to do some extra work to handle them. Any blockchain that spans enterprise boundaries (or even blockchains within enterprise boundaries) will need to deal with data integration issues that can be more difficult to solve than building the blockchain itself.
5. If you needed “miners”, who would they be and how would you compensate them?
In most current blockchains, including Bitcoin and In Ethereum, "miners" are all about validating the consistency of the blockchain and adding blocks. They won't do this work for free. Cryptocurrency ICOs are extremely popular, and it's easy to pay miners with cryptocurrency (after all, that's what Bitcoin and Ethereum do), but it's hard to imagine enterprise blockchain projects doing the same.
6. What are your performance requirements? How will you meet them?
The Bitcoin and Ethereum blockchains currently process approximately 12 transactions per second. For many enterprise applications, this is too slow, by orders of magnitude. You need to think about what kind of performance you need, and how you're going to achieve it. There are many possible solutions, including Bitcoin’s Lightning Network, which replaces the computationally intensive “proof of work” performed by miners, and permissioned blockchains such as Hyperledger’s Fabric.
7. Are there any legal issues?
Recently, I saw several people asking whether blockchain applications can comply with GDPR (General Data Protection Regulation) and others Regulation. This is undoubtedly uncharted territory. I think the answer is that blockchain cannot comply; the answer will depend on the data you store in the blockchain, how the data is used, andHow private or public the blockchain is.
IV What challenges does my country's blockchain development face?
At present, the current development status of my country's blockchain technology is that there are many patents, few papers and codes, no independent secure and controllable underlying platform, and no software and hardware. The integrated platform 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.
IV Problems faced by blockchain
Main 2 issues
The first blockchain generally establishes decentralized security maintenance through an incentive system mechanism, but one disadvantage is that the general incentive system will issue coins, which is not supported in China
The second is the technical bottleneck. The TPS of blockchain is generally not high and cannot support the implementation of a large number of applications
Blockchain technology is a new distributed infrastructure and computing paradigm that can Realize 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 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.
VII 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, blockchain technologyApplication of technology in the financial field.
Since 1978, China's financial system has evolved in the direction of marketization, standardization, diversification, and internationalization. Both the scale and complexity of China's financial system have increased rapidly and non-linearly. The relationship between various banks, banks, financial institutions, and financial sub-markets is close 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 of 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.
ⅧWhat are the shortcomings of blockchain technology?
At present, in practical applications of blockchain technology, there are still problems such as low performance, low transaction frequency per unit time, and technical application ecology. There are many problems such as lack of environment, insufficient relevant application cases, and rampant scammers under the guise of blockchain.
