A. Advantages of Blockchain Technology Classification of Blockchain Technology

The development of Blockchain technology is becoming more and more prosperous with the continuous expansion of applications. The strong development momentum coming from the needs of various industries has brought about rapid changes in blockchain technology, which has attracted more and more attention to the achievements of various industries. From professional technology to resources, they are constantly concentrated in this industry, thus The development of blockchain technology has entered a new stage, and the impact brought by the development of this blockchain technology has also attracted much attention.

When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.

How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.

“Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a ‘machine that creates trust’. "Bubi Company is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.

The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it cannot be tampered with Timestamps can effectively solve problems such as data tracking and information anti-counterfeiting.

Will it become the next trend of Internet finance?

Although blockchain emerged with Bitcoin, the derived value of this technology has transcended digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved.

In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect payment systems, securitiesFinancial infrastructure such as settlement systems and transaction databases; later this technology will also be expanded to general financial services, such as credit systems, "anti-money laundering", etc.

“The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. Quan and others have a profound impact." Li Yan said.

Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.

Blockchain technology will affect many industries

“Blockchain technology has been widely used in the era of big data.” Li Yan said frankly that in addition to the Internet financial field, Blockchain technology has been applied in many fields and has shown great prospects.

For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.

In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.

“Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any lack of Blockchain technology will be useful in all areas of trustful production and life."

The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted The new development of various industries, the impact of this driving force on society, and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting to see, expecting this brand-new technology to be used by various industries. Better benefit all industries.

B. What effect does blockchain have on real life?

Blockchain is essentially a disintermediated database that uses a blockchain data structure to verify and A new distributed foundation that stores data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. Architecture and computing methods. In layman's terms, blockchain is a distributed accounting technology, which has the characteristics of decentralization, non-tampering, and node consensus mechanism. Although it sounds a bit obscureIt’s difficult to understand, but it can actually bring tangible benefits to our daily lives:
First, blockchain technology can be used to establish a traceability mechanism for food and vegetables, fundamentally eliminate source pollution of food and vegetables, and provide the common people with safe, hygienic, green food and vegetables. , so that everyone can buy with confidence and eat with comfort;
Second, blockchain technology can be used to store various ownership certificates and notes and transcripts, completely eliminating the occurrence of fake certificates, fake files, fake academic records, fake medical records, fake transcripts and other fraud incidents;< br />Third, blockchain technology can be used to conduct community election voting, completely eliminating fake votes and truly achieving openness, fairness and impartiality. Build a democratic community and achieve democratic governance.
In addition, blockchain technology can also be used in many aspects of daily life such as charity fundraising and commodity anti-counterfeiting.

C. Why should blockchain technology be used in the financial field and what are its substantial benefits

The main advantages of blockchain technology in the financial field are disintermediation and great cut costs.

First of all, the financial industry currently needs to conduct layer-by-layer audits to control financial risks to prevent single points of failure and systemic risks, but this also results in high internal costs. And due to the increasing number of regulatory regulations, especially the 2008 financial crisis, the threshold for financial control has continued to rise, and the war on terrorism has led to the scope of anti-money laundering and counter-terrorism financing, which has gradually expanded the breadth and depth of supervision, resulting in the entire financial The regulatory costs of the system have increased dramatically. In this case, blockchain technology can greatly reduce costs for the entire financial system through tamper-proof and highly transparent methods.
According to a report released by Santander, Spain’s largest bank, if all banks around the world use blockchain technology internally around 2020, they will save approximately US$20 billion in costs per year. Such data is enough to illustrate the tremendous changes and breakthroughs that "blockchain" has brought to the traditional financial field.

In addition, due to historical reasons, traditional financial institutions rely on central clearing houses for settlement and clearing, and the resulting problem is low efficiency. Traditional cross-border settlements go through institutions like SWIFT, so cross-border wire transfers are often calculated on a daily basis. However, when Bitcoin uses blockchain technology, it has been running perfectly for seven years without a centralized operating organization. Not only can it achieve real-time settlement and clearing, but there has been no accounting error.
So, if all financial systems can achieve decentralized real-time settlement and clearing, it will not only greatly improve global financial efficiency, but also change the pattern of global finance.

D. What consensus mechanisms are currently used in blockchain and what are their respective advantages, disadvantages and scope of application

1. What is the technology of blockchain?
< br />If we assume that the database is a ledger, reading and writing the database can be regarded as an accounting activity. The principle of blockchain technology is to find out the accounting information within a period of time.The fastest and best person will keep accounts, and then send this page of information to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.

Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block. Blockchain is a general term for technical solutions similar to NoSQL (non-relational database). It is not a specific technology and can be implemented through many programming languages ​​and architectures. There are also many ways to implement blockchain. Common ones currently include POW (Proof of Work), POS (Proof of Stake), DPOS (Delegate Proof of Stake), etc. The concept of blockchain was first proposed in the paper "Bitcoin: A Peer-to-Peer Electronic Cash System", written by an individual who calls himself Satoshi Nakamoto (or group). Therefore, Bitcoin can be regarded as the first application of blockchain in the field of financial payments.

2. What is the principle of blockchain?

Combined with the definition of blockchain, we need these four characteristics before we can consider it: Decentralized , Trustless, Collectively maintain, Reliable Database. And the four characteristics will lead to two other characteristics:

Open Source (Open Source) and Anonymity (Anonymity). If a system does not possess these characteristics, it will not be considered an application based on blockchain technology. Decentralized: The entire network has no centralized hardware or management organization. The rights and obligations between any nodes are equal, and the damage or loss of any node will not affect the operation of the entire system. Therefore, the blockchain system can also be considered to have excellent robustness. Trustless: There is no need for data exchange between each node participating in the entire systemMutual trust, the operating rules of the entire system are open and transparent, and all data content is also public. Therefore, within the rule range and time range specified by the system, nodes cannot and cannot deceive other nodes. Collectively maintain: The data blocks in the system are jointly maintained by all nodes with maintenance functions in the entire system, and anyone can participate in these nodes with maintenance functions. Reliable Database: The entire system will be divided into databases so that each participating node can obtain a copy of the complete database. Unless more than 51% of the nodes in the entire system can be controlled at the same time, modifications to the database on a single node are invalid and cannot affect the data content on other nodes. Therefore, the more nodes and stronger computing power participating in the system, the higher the data security in the system. Open Source: Since the operating rules of the entire system must be open and transparent, for the program, the entire system must be open source. Anonymity: Since nodes do not need to trust each other, there is no need to disclose their identities between nodes, and every participating node in the system is anonymous.

3. What is blockchain finance?

In 2016, innovators will be innovated. The new round of technological revolution will address the challenge of trust between strangers in the sharing economy while destroying the basis for such platforms to make money.

Traditional intermediaries

Although the sharing economy effectively challenges the status quo and has strong innovative attributes, it still adopts a very traditional business model.

The most common method of charging commissions on transactions has been used for centuries. Today, technology has made many things possible, but it still cannot completely replace intermediaries.

When P2P platforms and other online marketplaces first emerged, people were talking a lot about disintermediation, a new way of connecting people directly through the Internet, bypassing traditional intermediaries. Indeed, even though we have experienced how much more convenient new markets are and the possibilities of transacting with a variety of suppliers, we still rely heavily on intermediaries today. The fact is that today’s biggest new businesses are giant intermediaries, whose scale is beyond imagination, like Alibaba, Amazon, eBay, and Uber.

Is there a technical solution that can completely remove the intermediary between transaction parties? Is there a system where you can trade directly with anyone and be safe from being cheated, but no one owns the system so there is no commission taker.

Blockchain technology makes this possible. Blockchain is the core technology of BitcoinThis technology is extremely innovative and can be used to build a completely transparent, ownerless and decentralized system, which can ensure the safe transactions of various transaction parties, including people and enterprises, without any form of intermediary.

Naturally, a lot of resources flow to the blockchain. The blockchain has also had a considerable impact on the financial and legal industries, and will eventually become rampant in these two industries, or provide the best Opportunity, it's all about how you look at it.

Decentralized Finance

In 2015, probably due to their high sensitivity to the growth of the alternative finance market, nine investment banks targeted blockchain technology finance. The services jointly developed the open standard. Last year saw constant activity discussing the future of blockchain technology and the launch of Slock.it, one of the first technology stacks for the decentralized sharing economy.

What does the sharing economy look like under the blockchain?

If you want to continue to earn commissions in the sharing economy, you must create a new business model.

Of course, the blockchain market will still require some investment. Developers may be happy to spend time solving code that plagues the system. However, I have yet to meet the overdue branding consultants, designers or businesspeople who have similar ideas or are willing to invest. Code alone cannot help the blockchain market enter the mainstream.

But blockchain will flourish, and by getting rid of annoying intermediaries, it can almost be predicted that it will definitely be cheaper than the existing sharing economy. By then, the giants will be forced to start response.

Will the old sharing economy repeat history, decline due to its belief that it is indestructible, and be quickly replaced by competitors that are more flexible and equipped with technology? Or will you experiment, find a profitable market in Sharing Economy 2.0, and beat the game?

What about credit?

Credit is the most frequent word in all discussions related to the sharing economy, and it is quite complicated and tricky. The current collaboration platforms have made it very clear: we can improve the level of trust in the sharing economy; we can take optimal measures to ensure that users trust our platform and transact on it, but we cannot guarantee that transactions between people are trustworthy. The blockchain solution solves the above problems.

The transaction system in the blockchain is immutable, and each transaction can be tracked within the assigned ledger. Smart contracts fully set parameters and conditions for all two-party transactions, so the blockchain is no longer needed. Any "trusted intermediary" or guarantor of credit between strangers.

By 2017, regulators will realize that they need to completely rethink the rules and regulations in the sharing economy. At that time, each transaction party will reach hundreds of millions of independent contracts in the blockchain. One solution is to type rule code into the system.

When the sharing economy first appeared around 2008, many people cheered, believing that it would lead us into a new inclusive and sustainable economy, and that it would lead us into the post-capital paradigm in the future. a democratizing force. However, (so far) this is not the case. The same was true when the Internet first emerged. It was utopian in its initial stages, so people who hold the same transformative expectations for blockchain are likely to be disappointed. Even so, it won’t hurt in the least that blockchain will shake up the giants of the sharing economy.

4. Blockchain community

Bubi Blockchain focuses on the innovation of blockchain technology and products. It already has a number of core technologies and developed its own Blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely.

Features and Advantages

It has achieved a number of core technological innovations and developed its own basic blockchain service platform, which has been used in equity, supply chain, points, credit, etc. application in the field.

Fast transaction verification

By optimizing key transaction links such as signature algorithms, consensus mechanisms, and ledger storage, Bubi blockchain can achieve fast transaction verification in seconds.

Efficient ledger access

Bubi blockchain’s adjustments to the ledger storage structure can save 90% of storage space and reduce the long-term operation of the system, resulting in ledger access Risk of performance degradation.

Multiple asset issuance

Joint signature control

Allows multiple users to be set up under the same account, and sets corresponding permissions for different operations to meet the usage scenarios of multi-party signature control.

Built-in smart contract

A smart contract is a set of promises defined in digital form. The blockchain becomes a participant in the contract and is responsible for maintaining, saving and automatically executing the contract.

On-chain exchanges

Compared with traditional centralized exchanges, in a trading platform built with blockchain, all transactions are verified, completed and saved on the chain. Ensure user transaction security.

What Bubi Blockchain wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved. In the future, if the network itself can checkout, we can transfer directly without going through an intermediary.

E. Blockchain technologyAdvantages

Sharing source: District View Network:

“Blockchain is a shared distributed database technology. Its advantages are mainly reflected in distributed decentralization and no need for trust. System and non-tampering and encryption security."

1. The meaning of blockchain technology

Blockchain (BlockChain) technology is a method that uses decentralized consensus Mechanism to maintain a complete, distributed, non-tamperable ledger database technology, which allows participants in the blockchain to implement a unified ledger system without establishing a trust relationship. Blocks are public ledgers and are maintained at multiple points; chains are stamped with timestamps and cannot be forged. Blockchain is essentially a technology that values ​​security and credibility over efficiency.

There is a database behind all current systems, which is a big ledger. Then who will keep this ledger becomes very important. Now it’s whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger.

Thus, these data will become very safe. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for all people to participate in accounting, and it will bring about innovation in accounting methods.

2. Technical advantages of blockchain

1. Distributed decentralization

Since every node and miner in the blockchain must follow the same Accounting transaction rules, and this rule is based on cryptographic algorithms rather than credit, and each transaction requires the approval of other users within the network, so the decentralized trading system does not require the endorsement of a third-party intermediary structure or trust organization.

At present, both traditional trading systems and third-party trading systems are based on central account books. The central account books play the role of information custodian, and each transaction requires a third party. Endorsed by intermediaries or trust institutions, this is a centralized trading network.

2. No need to trust the system

In the blockchain network, through the self-restraint of the algorithm, any malicious behavior that deceives the system will be rejected and suppressed by other nodes. Therefore, the area The blockchain system does not rely on the support and credit endorsement of a central authority.

In traditional credit endorsement network systems, participants need to have enough trust in the central organization. As the number of people participating in the network increases, the security of the system decreases. Contrary to the traditional situation, in the blockchain network, participants do not need to trust anyone, but as the number of participating nodes increases, the security of the system increases, and the data content can be fully disclosed.

3. Non-tampering and encryption security

The blockchain adopts a one-way hash algorithm, and each newly generated block is strictly advanced in linear order according to time, and time is irreversible. Due to its nature, any attempt to intrude and tamper with data information in the blockchain can be easily traced, leading to rejection by other nodes, thus limiting related illegal activities.

F. Who knows a general introduction to the LKL blockchain project?

What is a blockchain?
What is a blockchain? Blockchain? The simplest explanation is: Blockchain is an electronic accounting technology. The most powerful thing about this technology is its de-Chinese feature. The decentralized nature gives this technology the advantages of high security and low cost, making it a rising star.
The editor believes that the most effective way to understand blockchain must start with keywords. The first is "decentralization". The literal explanation is to remove the role that originally played the center. For the first application scenario of blockchain - electronic payment, it will be a means of eliminating intermediary companies such as banks, Alipay, and Paypal when making online electronic payments between individuals.
Take LKL (Little Apple) payment as an example. The method is to record Bitcoin payment transactions every second through different nodes (computers) on the Internet. And will be "liquidated" every few minutes, that is, in the Bitcoin world, a block is generated every few minutes, and after it has been certified by nodes around the world and meets the standards, this block containing a few minutes will be The record of every transaction using LKL (Little Apple) is added to the blockchain and becomes a historical fact that can never be changed.
And this blockchain is so transparent that everyone in the world can check it. Then, different nodes (computers) in the world will receive the information that the new block has appeared, and store the new blockchain content in their own computers.
National Accounting Book
So in theory, if anyone wants to change the content of the blockchain to benefit themselves, they must change the records in every node (computer) in the world. In fact, since blocks are added to the blockchain through a consensus system to recognize the fact that the longest chain is correct and has not been changed, the operation requires changing 51% of the node (computer) records in the world to have a chance. arrive.
But it should be noted that it is actually impossible, thus constituting a high degree of security for digital encrypted assets. Therefore, some people will understand the blockchain as a national ledger stored among the people, and each block is the paper on each page.
At the same time, because LKL (Little Apple) The payment system uses voluntary honest nodes (computers) for accounting and settlement. Compared with traditional banks, Alipay and other intermediary companies, it saves handling fees and makes both buyers and sellers fairer. On the other hand, for companies, using blockchain for accounting and liquidation can save the cost of purchasing, maintaining and preventing downtime of original central servers.
Because the accounting of the blockchain is operated 7x24, and because there are different nodes in the world, there is no need to worry about the problem that "once the system fails, the operation will stop", it can be understood as the Russian folk If a node fails, British private nodes can make up for it.
Therefore, the decentralized nature of blockchain gives buyers and sellers the two major advantages of high security and low cost, making it likely to be suitable for application in the field of payment in tomorrow's world. Of course, blockchain payment is just the tip of the iceberg in its applications. There are many different applications in bud, waiting to bloom everywhere!

G. What are the benefits of such a blockchain for universal accounting

National accounting is open and transparent, irreversible, and cannot be tampered with.
Blockchain technology is just a bottom-level technology. It is only responsible for recording the information on the chain to ensure that it is irreversible and cannot be tampered with. However, the authenticity of the information itself cannot be distinguished. Therefore, it is still necessary to apply blockchain to life itself to innovate and exert its huge value.

H. Advantages of blockchain technology

1. Decentralization:
Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no center In addition to the self-contained blockchain itself, each node realizes information self-verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.
2. Openness:
The foundation of blockchain technology is open source. In addition to the private information of the parties to the transaction being encrypted, the data of the blockchain is open to everyone. Anyone can access it through the public The interface queries blockchain data and develops related applications, so the entire system information is highly transparent.
3. Independence:
Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can Verify and exchange data automatically and securely within the system without any human intervention.
4. Security:
As long as 51% of all data nodes cannot be controlled, network data cannot be manipulated and modified at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.
5. Anonymity:
Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.
Digital China is a major development strategy clearly proposed for the first time in the report of the 19th National Congress of the Communist Party of China. Digital technology applications represented by cloud computing, big data, and mobile Internet are no longer limited to the economic field, but have widely penetrated into the public sector.Public services, social development, and all aspects of people’s lives require macro coordination, overall control, and integrated development.
With the new round of technological revolution and industrial transformation continuing to deepen, the wave of digital economy is unstoppable on a global scale. Developing the digital economy has become a global consensus and is known as the key to opening the door to the fourth industrial revolution.
Adhering to the world-wide inclusive humanistic spirit of the University of Nice, always embracing changes, standing at the forefront, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of Nice's "Doctorate in Blockchain and Digital Economic Management" ( DDE for short) came into being.
This is the cornerstone to empower digital economy industry managers with a global vision and global integration thinking, integrate knowledge, intelligently operate the digital economy, promote the sustainable development of the industry, and contribute to a community with a shared future for mankind. Therefore, the DDE project will advance in collaboration with colleagues in the digital economy field.

I. What are the advantages of blockchain technology

Recently, many friends have come to ask questions related to blockchain, such as the specific advantages of blockchain, why invest in blockchain, and what benefits it can bring? Is it not allowed to invest in real estate and wait for appreciation; invest in stocks and bonds Isn’t this a mature market? Why invest in the newly emerging blockchain? Does blockchain have any investment value? A series of questions, etc., I have made the following summary, which basically summarizes most of them. Answers to related questions:

Advantages of Blockchain

Blockchain is regarded as an important part of the fourth industrial revolution. We all know that every The industrial revolution will bring about a leapfrog progress in human productivity. The history of human development is actually the history of one-step progress in productivity

It can be roughly summarized in the following four aspects:

1. Blockchain has Good market prospects; as an emerging technology, blockchain is recognized by many professionals, including investors, with an expected market value of approximately US$60 billion in 2020, and it is expected that the value of blockchain in the global market will reach 2024 20 million US dollars, the considerable market prospects of blockchain are obvious.

2. The cost of blockchain is low; compared with centralized models such as credit card payment and stock trading that rely on third-party intermediaries, the decentralized distributed structure of blockchain saves investors It eliminates high handling fees and transaction fees, saves investment costs, and improves transaction processing efficiency.

3. Blockchain is more secure and stable; the traditional centralized model often faces serious credit crises, but since every transaction in the blockchain is tracked and permanently recorded by distributed public ledgers, it is greatly reduced. It eliminates counterfeiting, avoids losses caused by third-party credit issues, and provides security for investors' transactions.

4. The programming attributes of the blockchain are more standardized; traditionalMarket investors often have their returns affected by confusion at the market level, while the programmability of the blockchain makes the market level clear and is an innovative technology that can change people's lives.

I hope it can help you solve related problems. For more details or if you have any questions, please feel free to ask or discuss!
