『一』 Why do many people say that blockchain is a lie?

Blockchain is not a lie, but lies under the guise of blockchain. A liar. In fact, blockchain scams take advantage of people's lack of understanding of the technology, and then scammers rely on a variety of fancy methods to set up scams. Many people only look at the surface when making investments, and are eventually lured into the trap by high profits.

In current society, more and more people are willing to take the risk to invest in order to obtain huge returns, but not everyone can make a profit. After all, there are benefits. There are many people squatting and watching, and they will set traps for people to take the bait.

Notes

Blockchain is a technology , simply put: this technology is based on new ways of data management such as cryptography. Blockchain technology has broad application prospects because of its advantages such as decentralization, non-tampering, full traceability, and traceability. Issuing coins is an act derived from blockchain technology. At present, the vast majority of blockchain applications that focus on issuing and speculating coins are suspected of illegal fund-raising.

Blockchain technology is still in its early stages of development, and its application is also difficult to implement. If you rely solely on a white paper to claim that there is an application, it is an act of deception in itself.

『二』 Can pi coins buy a car? Can pi coins be used to exchange cars?

Recently, an APP called "Pi Network" suddenly became popular on the Internet. According to relevant publicity, as long as there is You can participate in "mining" with just a mobile phone. It is a blockchain project with extremely low barriers to participation. It is reported that the virtual currency you receive can even be used to exchange cars. At this time, many people are curious. Is it true that pi coins can be exchanged for cars? Of? The authenticity of car exchange with PI coins has yet to be investigated. From the relevant forums of this virtual currency, we can learn that there is no statement about the authenticity of car exchange. At present, no 4S store in China has stated that it can pass PI. Coins are used for transactions, so it is still unknown whether PI coins can be used to exchange cars. Where can I buy a car with pi coins? There is no place that explains that you can use PI coins to buy a car. I entered the so-called "PI Automobile Trading Mall" website and could not find the car purchase entrance. For example, when I clicked on the "I want to buy a car" option, only a message interface came out. Series There are only introductions to some car models, but when viewing the steps to buy a car, the website automatically changed to "steps to rent a car." In addition, according to the news information on the website, it can be learned that PI Mall is currently still in the simulation payment experience testing stage. The seller will not ship the orders for test payment. The owner's reply from the product evaluation in the virtual car purchase interface also confirmed that it is currently unavailable for purchase. The fact is that PI coins are not used to purchase cars and other shopping needs. Although it’s fun to make money, be careful not to fall into the virtual currency trap! ! ! The central bank has stated that virtual currency-related business activities are illegal financial activities. Previously, relevant departments also provided information on the speculation of virtual currency transactions by banks and payment institutions.After interviewing some banks and payment institutions regarding service issues, the People's Bank of China stated: "Virtual currency trading and speculation activities disrupt the normal economic and financial order, breed risks of illegal cross-border transfers of assets, money laundering and other illegal and criminal activities, and seriously infringe on the property security of the people." The author also learned from consulting lawyers that virtual currency exchange and other virtual currency-related businesses are all illegal financial activities. Even the services provided by overseas virtual currency exchanges are illegal in China, such as Bitcoin, Ethereum, Tether, etc. Neither the so-called virtual currency nor stable currency can be used as currency to circulate in the market. In addition, Xinhua News Agency has also questioned related "mining" software. We all know that "mining" projects require the design of complex algorithms to achieve the purpose of encryption security, so many "miners" have to purchase high-performance Only computers can meet the mining needs, but mining PI coins consumes neither power nor traffic. It can be achieved by moving your fingers on your mobile phone. The credibility and safety of mining in this way have yet to be studied. Virtual currency costs nothing, so what do I have to lose? 1. There is a risk of gradually falling into a trap. There are many frauds under the guise of "blockchain" that have very low thresholds in the early stage. They attract users by freeing money and simple operation. As the number of users gradually increases, And as old users get deeper into the trap, they will start to lure users to invest through referral rebates in order to seek violence. Many people have lost the ability to distinguish right from wrong at this stage and have been deceived without knowing it. 2. A waste of time and energy. Even if you don’t have to invest any money in mining virtual currency, we still have to spend a lot of time on relevant web pages and forums every day. However, as we accumulate more and more “air coins”, our mentality will inevitably change. , will affect your normal life to a greater or lesser extent. If you end up with a bad deal, all the time and energy spent in the early stage will be wasted, and it would be better to go to QQ space to steal food. 3. There is a risk of privacy leakage. Friends who have learned about related virtual currencies know that if you want to download a mining APP, you need an overseas ID to download and use it. During this period, you need to log in to various "unique" websites and use it yourself. Personal privacy may have been leaked unknowingly, and the so-called miners "ran naked" while digging. It should be noted that the above statement is not to discredit PI Coin, nor does it mean that there must be traps in the project. It just hopes that consumers can stay more vigilant when participating in related activities. As the saying goes, there is no free lunch in the world. There is no risk-free blockchain project. It is best to buy a car through normal channels. Only by rationally "cutting leeks" can you avoid becoming a "leek".

『三』 What kind of sparks can be created when cars meet blockchain?

Speaking of blockchain technology, it became a familiar word to everyone almost overnight and became a It has become a technological trend pursued by many industries, and the automotive industry is no exception.

According to the MOBI statement, the alliance aims to create common standards and APIs (application programming interfaces) among alliance members to findSeeking to establish a new digital mobility ecosystem that allows enterprises and consumers to have security and sovereignty over their driving data, manage ride sharing and vehicle sharing transactions, and store vehicle identity and usage information.

However, Zhu Youping also pointed out that the scale of automobile companies is relatively large, and the alliance blockchain will have a more profound impact on automobile companies. However, the biggest difficulty in the current application of blockchain technology in the automotive industry is the This understanding is insufficient. For this reason, alliances like MOBI still need more members to join. On the one hand, it is to make more car companies aware of blockchain technology, and on the other hand, it is to allow the data of car companies to be shared.

As a technology that has just emerged in recent years, blockchain is still in its early stages of development. Whether it can be used on a large scale in the future is still unknown. Even if it can be used on a large scale, it will take a long time. time. But it is undeniable that the emergence and application of blockchain technology have given the automotive industry more possibilities for development.

This article comes from the author of Autohome Chejiahao and does not represent the views and positions of Autohome.

『四』What is blockchain and its application in the automotive field

1. The decentralization, transparency and trust of blockchain technology are to solve the current problems Problems such as leakage of user privacy, poor dispersion of maintenance services, and irregularities in the automotive industry have brought opportunities. The key to the application of blockchain in the automotive field lies in the construction and integration of car identity and user credit systems to create car logos, completely record key information during the manufacturing and use of cars, promote the standardization of the traditional automotive industry chain, and establish a reliable system for car companies. The service platform quality control system and optimized inventory dynamic management provide users with better repair, maintenance and second-hand car trading services. Combining car identity and personal credit, it is connected to the blockchain system and can transform the original car sharing business process. In the future, blockchain, as the underlying technology, will be combined with edge technologies such as the Internet of Things and big data to achieve safe interconnection of different smart devices, continuously improve the processing capabilities of blockchain technology, and accelerate its development in the fields of autonomous driving and intelligence. application.

3. Blockchain system information transparency, tamper-proof, and forgery can effectively solve this problem, which will have an impact on the financial Internet of Things, supply chain, government services and other fields. deep influence. Due to its transparent, reliable and traceable characteristics, blockchain technology can build a car identity and completely record the source of car parts and production processes, sales channels, use and maintenance, vehicle positioning and other data to promote into the traditional automotive industry chain. "Production, supply and marketing after market" standards. At the same time, a tamper-proof and securely encrypted user credit system can be built through the blockchain to record, store, and integrate user online transaction information and credit evaluations such as asset information, user information, and user behavior. Because the application of car retail, leasing, sharing and other scenarios is essentially an extension of the personal credit system, the blockchain system will eventually bring information such as identity, user credit and service history to owners through the blockchain system, which will be associated with car identities to improve the security of interconnection. sex, realizing the application of blockchain autonomous driving in fields such as Internet of Vehicles and vehicle sharing.

『Wu』Blockchain empowers new energy vehicle business - separation of vehicle and electricity

The blockchain that everyone hears in the news now is often associated with virtual currency , in fact the blockchain is far more than that. First, blockchain is a trust engine and a technology that guarantees trustworthy data; second, blockchain is a technology that changes production relations. There is a saying that of the two major technologies that change the world (artificial intelligence, blockchain), artificial intelligence changes productivity, and blockchain changes production relations; third, blockchain is a platform technology that integrates resources and can Integrate cross-industry resources, including finance, technological innovation, and talent participation, into various real industries effectively and creatively. In the following lecture, I will use specific cases to illustrate.

What challenges and opportunities do we see when further promoting the development of new energy vehicles? First of all, the contradiction between battery cost and life is undoubtedly a very big challenge. The high cost of batteries has brought about issues with consumers’ car purchase costs and willingness to purchase cars. This is bound to be detrimental to the rapid growth of the new energy automobile industry.

The second is that the overall battery technology has not yet been finally "settled" and is still evolving. This is certainly not a bad thing, only a truly viable industry will do this. Academician Zhang just said it very well. The endless emergence of new technologies will inevitably make vehicle manufacturers face the challenge of how to integrate rapidly growing technologies with their own product cycles.

The third issue is security. You may sometimes see battery fires in the news. According to relevant statistics, as of 2020, in the analysis of national electric vehicle safety accidents, accidents caused by battery problems accounted for more than 60%.

In addition, the battery usage efficiency of new energy vehicles greatly limits the travel range of a single charge. Although it has been greatly improved compared to before, it still inevitably affects the travel experience.

So, what kind of digital challenges do we face in order to solve the above problems? The key is that power batteries have high product value and potential environmental impact, so the life cycle is very long, spanning many industries from production, vehicle integration, user use, secondary recycling as energy storage facilities, electricity use, and final environmental protection recycling. . Cross-industry data collection and trustworthy transfer and sharing are very difficult. Especially for battery manufacturers and vehicle manufacturers, how can these two data islands be connected and how can they share data? During battery use, consumers and charging station operators also have some data. Local power suppliers in the energy storage process and environmental recycling manufacturers in the recycling process will also have their own data. Furthermore, don’t forget that the financial industry can also be data-driven.Stakeholders: Power batteries account for more than 40% of the cost of a complete vehicle. From the perspective of resource integration, how can we introduce financial resources on the basis of trusted data transfer to reduce the cost pressure on vehicle manufacturers and consumers?

As mentioned earlier, blockchain is the engine for cross-industry data integration. It can allow data from different sources to pass privacy calculations and form digital twins on the premise that data ownership is effectively protected. This digital twin is highly targeted. Previously, when product problems occurred, it was difficult to accurately locate problems due to issues such as the inability to communicate cross-platform and cross-industry data, and the recall of automotive products was often blind.

For example, a problem was discovered and 600,000 vehicles needed to be recalled. Now, with the trustworthy data guarantee provided by blockchain technology, through cross-platform data integration and data analysis that was previously difficult to achieve - conducting very precise analysis of power batteries and new energy vehicles, we have discovered very high-granularity "Problem combinations" may be able to reduce the scale of the recall to thousands or even hundreds of units. Precise recalls not only guarantee the safety of consumers, but can also greatly reduce the costs of vehicle manufacturers.

The value of battery data has yet to be discovered, not just battery life cycle and overall usage. Another very important point is that among the various components of new energy vehicles, the data collected by the power battery energy supply system is the most complete. Such complete data is not only of high value in the business model of the power battery itself, but also valuable for improving user experience and even urban management.

It can be said that power batteries are the key to new energy vehicles. We can embed relevant IoT devices in the power battery; this IoT device is combined with blockchain technology to collect data on the premise of ensuring that the data is trustworthy, cannot be tampered with, and protects privacy. Not only can it form a trustworthy power battery Digital twins also help form credible and effective digital twins of new energy vehicles themselves. Previously, Molink Technology cooperated with Wanxiang Blockchain to launch the blockchain cellular wireless module and the PlatONE alliance chain data storage platform, which can enable the safe and trustworthy uploading of massive IoT device data to the cloud.

When it comes to business models, whether looking back at the development history of fuel vehicles or looking forward to the development prospects of new energy vehicles, how can the real industry effectively introduce financial resources? , are all important directions for expanding business value. Vehicle-battery separation means that based on the battery swap model, after the car owner purchases the entire vehicle, the battery management company repurchases the battery property rights, and the car owner obtains the right to use the battery through leasing. If the separation of vehicle and electricity can be done well, the power battery and chargingThe website can become an asset package and is separate from the new energy vehicle itself, so everyone can finance the asset package. This is not just a concept or a dream, we are already working with leading companies in the industry on this.

When this business model is further scaled up, it will bring several benefits. First, a collaborative network connects all parties involved in series battery production, sales, transportation, use, recycling, testing, transformation and reuse. Efficient and reliable battery circulation helps all parties benefit from measurement, distribution and settlement, and improves the efficiency of traditional business connection and collaboration; second Second, it can allow more financial resources to enter the new energy automobile industry in urgent need of social and financial resources in a credible way, effectively promoting its further development and growth. Third, develop a very good rhythm. In the early stages of the new energy battery industry, the business model brought about by the separation of vehicles and electricity is quite stable. No matter how technology evolves in the future, this industry will be able to effectively allocate financial resources, which in turn will bring very important and necessary vitality to the development of new technologies; fourth, for asset management companies and financial institutions, on the one hand, they can Penetrating supervision of assets can, on the one hand, control the operating income of assets in real time, effectively reducing asset and capital risks.

For consumers, the cost of purchasing a car will directly drop. For example, buying a car used to cost RMB 300,000, but now it only costs RMB 180,000 or RMB 200,000. The rest is to pay the monthly usage fee for separating the car and electricity, which will be promoted in the future. At the same time, it can also shorten charging time and alleviate battery life anxiety; for new energy battery manufacturers and vehicle manufacturers, it has the opportunity to introduce more financial resources, improve operational efficiency, improve battery safety, and slow down battery decay; for relevant government departments and management For institutions, through power batteries and IoT devices, and through blockchain technology to form credible and reliable digital twins and capitalize them, governance goals such as carbon neutrality can be better managed and achieved by integrating social resources. At the same time, it can also promote battery standardization and promote infrastructure construction.

To realize the separation of vehicle and electricity in new energy vehicles, we are currently facing some challenges: The first is asset-heavy: high initial investment in the construction of battery swap stations, financing The demand is huge; secondly, it is difficult for car companies to cooperate: it is difficult to apply and promote standardized technology, and different models of different car companies have significant differences; thirdly, the degree of standardization is low: it is difficult to open up and use it to create economies of scale; fourthly, the operation service system is imperfect: Batteries are transferred through multiple parties and are difficult to trace.

Why talk about challenges? Traditional information technology is difficult to establish trust among multiple parties and requires a complete top-level design. Faced with the above challenges, it is difficult to carry out a complete top-level design, which will inevitably lead to a situation of crossing the river by feeling for the stones. To ensure that the entire business direction does not get out of control during the process, the blockchain organization mustthe role played by industrial relations.

Not only cars, but all industries related to new energy energy storage, such as the energy infrastructure of future cities, can use the Internet of Things + blockchain + Privacy computing, through the creation of a trustworthy digital base, realizes trustworthy digital twins and capitalizes them, thereby reducing costs and increasing efficiency, and creating win-win social and economic value for enterprises, consumers, and government agencies. And these are not just in the planning stage, we have already put them into practice. This includes the capitalization of power batteries jointly promoted with partners, the use of blockchain-based battery and new energy management on electric buses, etc.

『Lu』 The blockchain Qubu APP is a platform supported by the government. Is it true that you can buy a car or a house in one year?

False, Qubu has been classified as It's a pyramid scheme and you still believe this, it's obviously the so-called agent who is making false propaganda.

『撒』 What is blockchain? If you understand these 9 questions, you will understand

What is blockchain? If you understand these 9 questions, you will understand
What is blockchain? What can blockchain do? How to make money with blockchain? I believe that many netizens are confused when faced with this new term. So how can we better understand blockchain and make this new technology available to us? The author has collected nine very common questions from the Internet. I hope that after reading this article, you will have a clearer understanding of blockchain.

Nearly omnipotent blockchain technology
Simply put, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Its core is distributed data, and the result is "decentralization." Blockchain technology can be applied to many scenarios in our lives. Next, let’s take a look at the analysis of blockchain technology!
1. Technology is a double-edged sword. While you are still using your mobile phone to play games, others are already using their mobile phones to make money every month! I want to try Jiaerwu Wuyi Wuba Lingyi Lacquer to make your mobile phone no longer a toy!
Just like nuclear energy is a physical technology, blockchain is an underlying technology at a technical level.
Nuclear energy can be used for atomic bombs and nuclear power generation. Similarly, blockchain can be used for the management of industries and life elements, which may make society more stable, or it may be used by bad guys as the fastest way to commit crimes. .
2. Talking about technical value apart from the application level is muddying the waters
As the underlying technology, blockchain has its application level and negotiation methods. Currently, some people talk about blockchain in terms of business models, some in terms of hardware, and some people talk about blockchain in terms of power distribution. It is gradually becoming clear in the market that blockchain is used in the design of technology combinations and business models, from hardware to software to business model to financial design and many other aspects. But not every blockchain can issue coins, and not every blockchain should issue coins.
3. Technology is decentralized, but the application is not necessarily
Blockchain technology is decentralized, but it can be decentralized or not in upper-layer applications. If it is applied to things, industries and projects that cannot be decentralized, it is not decentralized; if it is used to things where everyone can participate universally and have equal authority, then it can be decentralized.
Including coins on the blockchain, if a country adopts legal digital currency, the coins on the blockchain can also be centralized. The blockchain that supports the operation of Bitcoin is decentralized, but the alliance chain usually has one or more enterprises as the core control alliance, which becomes centralization.
Technology itself and what kind of business and political ecology the technology can support are completely different things.
4. What kind of people use what kind of tools
As a powerful tool, blockchain is powerful not only because of technology, but also because many talented people have invested in it. field, causing the energy of this technology to be amplified. As for whether the power of blockchain benefits society or cuts leeks? It is possible to make the world more turbulent or to make society more harmonious and beautiful.
On the positive side, more kind-hearted people will come in and reach more consensus, and there will be more legislation, restrictions and norms at the national level, which will ultimately allow us to use this technology to give more people opportunities; on the negative side, In other words, it is possible that more greedy and unethical people will come in to divide the wealth, and it is even possible that people in some countries and regions will use this new technology to commit crimes and terrorism.
5. Blockchain promotes the globalization of civilians
Under the blockchain, the global connection space is closer. The 6-degree space will become 5 degrees or even 4 degrees in the future. Blockchain can inspire The growth of various communities. The globalization of interest groups will become inevitable, and there will be various international communities and summits in the future.
6. Blockchain facilitates co-creation
For example, in the past, the connection between international singers and ordinary people had to go through several barriers, including record companies, agents, sales channels, etc. In the blockchain era, international singers publish their songs under blockchain technology. Everyone has the possibility to become a partner of an international singer, write songs for the international singer, or purchase Tokens to obtain dividend rights from distribution proceeds, etc., and enjoy records. Proceeds from distribution and downloads.
7. Trust will become convenient and low-cost
The combined effect of artificial intelligence, big data and blockchain can resolve disputes at the factual level. The tamper-proof nature of the blockchain allows hundreds or even tens of thousands of machines to maintain the same data and encrypt it. Basic facts will be trustworthy. On this basis, the corresponding contracted and authorized information cannot be changed. Replace manual systems with machines, breaking the loopholes in manual operations, the possibility of cheating and even corruption, so that everyone's information can be confirmed to be authentic and trustworthy.
On this basis, if the trust level of the business system is good, there will be trust between people in the process of executing the designed system.will be enhanced.
8． Interaction leads to creativity, and creativity generates income
Blockchain is a comprehensive ledger. Some exchanges are just ideas and creativity at the moment, but they may be the starting point of a certain career or even industry in the future. In the previous accounting system, there may not be value. However, under blockchain technology, values ​​that are not yet seen can be recorded. If this leads to products, creative people can benefit. Various human activities may be valuable, creative, and worthy of recording.
Extended from this, a better application of blockchain can record creative related models, introduction of business opportunities, etc., and put valuable things in an ecosystem. Blockchain can create new ones. A cooperative approach.
9. There will be more legal supporting facilities in the future
The world of blockchain is not a disorderly world. Technology will be used by people, and people are rational.
Records can resolve various factual disputes, and can also cause more issues such as authorization rights, patent and creative copyright management, and many other issues. In the future, there will be more legal supporting systems to not only standardize and manage service consumption and life, but also to avoid related risks and problems, and to avoid and combat crime

『8』 What is blockchain

In the simplest terms, a blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain network visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledgerCopy, whenever any member of the bank makes a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

『玖』 What are the main technical characteristics of blockchain?

“Blockchain is a shared distributed database technology, and its advantages are mainly reflected in distributed decentralization, There are three aspects: trustless system and non-tampering and encryption security.”
1. The meaning of blockchain technology
Blockchain (BlockChain) technology is a method that uses a decentralized consensus mechanism to maintain a A complete, distributed, non-tamperable ledger database technology that allows participants in the blockchain to communicate without establishing a trust relationship.Implement a unified ledger system. 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, the data becomes very secure. 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.
