1. What are the advantages of using blockchain technology to build a new business ecosystem?

The blockchain ecosystem can be viewed from the following two aspects:
The first is Self-ecology.
When we want to do something and need help from others, we often use a contract.
But if you use the token economy now, you can describe the future value and let more people participate in your value creation process through the consensus mechanism. When everyone embodies their own value in the token model When they come out, they can blend into each other.
This kind of integration is not a centralized organizational behavior, but a voluntary decision by everyone. Based on a consensus mechanism and an incentive mechanism, they come together and finally form a self-ecology.
The second is self-financing.
Any business without finance is like a body without blood. Therefore, when there is an ecology, it also needs to have the function of supporting it, and there needs to be a network system to transport blood and absorb the old and the new.
If we want to use blockchain to build a new business ecosystem, the first thing to do is to design a good economic model. Only in this way can the entire ecosystem grow and continue to create value.
What does blockchain turn into value? It is the consensus mechanism. For example, after Bitcoin was created by Satoshi Nakamoto in 2008, no one managed it at all. However, it relied on a simple and effective mining and release mechanism to build a value system worth hundreds of billions of dollars.
In addition, the blockchain can allow each subject to directly connect to the financial market or capital market through self-financial design.
Before, value creation and finance were separated. Many people worked hard, but the final profits were very limited, while the capital market achieved high returns. But by designing financial needs independently, blockchain will allow the capital market to satisfy you instead of catering to them.
So self-ecology + self-finance, this is a business model in the future.
Blockchain is the core supporting technology of the digital cryptocurrency system represented by Bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transactions based on decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Coordination and collaboration thus provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.

The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top All domain names have been registered, which has had a relatively large impact on the domain name industry.

2. Advantages of blockchain technology

Sharing source:

“Blockchain is a shared distributed database technology. The main advantages are distributed decentralization, trustless system and non-tamperability.Three aspects of modification and encryption security. ”

1. The meaning of blockchain technology

Blockchain (BlockChain) technology is a method that uses a decentralized consensus mechanism to maintain a complete, distributed, and irreversible The technology of tampered ledger database allows participants in the blockchain to implement a unified ledger system without establishing a trust relationship. The block is a public ledger and is maintained at multiple points; the chain is stamped with a timestamp ( Timestamps), cannot be forged. Blockchain is essentially a technology that focuses on security and credibility over efficiency.

All current systems have a database behind them, which is a large ledger. Then it becomes very important who will keep the ledger. Now it’s whoever’s system keeps the ledger. Each bank’s ledger is kept by each bank, and Alipay’s ledger is kept by Alibaba. But now in the blockchain system, in the system Everyone in the system can have 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, and 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 ledger content to all other people in the system for backup during this period. In this way, everyone in the system has a complete ledger.

Therefore , 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. The cost of such tampering is extremely high, making it almost 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 no transaction errors have occurred. 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 , it will bring about innovation in accounting methods.

2. Technical advantages of blockchain

1. Distributed decentralization

Due to 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. At the same time, each transaction requires the approval of other users in the network, so a decentralized trading system does not require A set of third-party intermediary structures or trust institution endorsements.

At present, both traditional trading systems and third-party trading systems are based on central account books, and the central account books play the role of information For the role of the custodian, each transaction requires the endorsement of a third-party intermediary or trust institution, which is a centralized transaction network.

2. No trust system required

In the blockchain network, Through the self-restraint of the algorithm, any malicious deception of the system will be rejected and inhibited by other nodes. Therefore, the blockchain system does not rely on the support and credit endorsement of a central authority.

Traditional credit endorsement network In the system, 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.

3. One article summarizes nine major benefits that blockchain technology brings to enterprises

The first blockchain technology in 2009 The launch of Bitcoin has transformed blockchain from a theoretical application into a real-world application, proving that this digital distributed ledger technology actually works. Since then, many enterprise organizations have been testing how to make blockchain work for them.

Now, well-known companies, government organizations and non-profit entities are also trying to use blockchain to improve existing processes and enable new business models.

Blockchain’s value stems from its ability to share data between entities in a fast and secure manner—without any entity being responsible for protecting the data or facilitating transactions.

"This is a transaction ledger with unique characteristics that help solve problems in our systems and processes," said Associate Professor in the Department of Information Technology and Analytics at American University and Research Fellow at the Kogod Center for Cybersecurity Governance Ayman Omar explains.

From Maoqiu Technology’s perspective, blockchain and its features can, in fact, help enterprises in a variety of ways – whether they use a public blockchain network or choose a private or permissioned zone-based one. Blockchain applications.

Maoqiu Technology The following are the main advantages of blockchain:

Blockchain creates trust between different entities where trust does not exist or is unverified. As a result, these entities are willing to engage in commercial transactions involving transactions or data sharing that they might not otherwise do, or would require an intermediary to do so.

The realization of trust is one of the most promising advantages of blockchain. Its value is evident in early blockchain use cases that facilitate transactions between entities that are not directly related but still need to share data or make payments. Bitcoin, and cryptocurrencies in general, are prime examples of how blockchain enables trust between participants who do not know each other.

Daniel Field, Head of Blockchain at UST Daniel Field, Head of Blockchain at UST, a global provider of digital technologies and services, explains that when there is no central actor facilitating trust, blockchain The chain has truly proven its value.

Thus, in addition to enabling trust when participants lack trust because they don’t know each other, blockchain can enable data sharing in an enterprise ecosystem where no single entity is solely responsible.

Supply chain is a good example. Multiple businesses—from suppliers and transportation companies to manufacturers, distributors, and retailers—want or need information from others in the chain, but no one is responsible for facilitating the sharing of all this information. Blockchain solves this problem with its decentralized nature.

The security of blockchain-enabled systems is another major advantage of this emerging technology. The enhanced security provided by blockchain stems from how the technology actually works. Blockchain creates an immutable record of transactions through end-to-end encryption, which keeps fraud and unauthorized activity at bay.

Additionally, data on the blockchain is stored in a computer network and is nearly impossible to hack (unlike traditional computer systems that store data in servers). At the same time, blockchain can limit access by anonymizing data and requiring permissions, solving privacy issues better than traditional computer systems.

Blockchain can also reduce costs for companies, increase the efficiency of processing transactions, and reduce manual tasks such as aggregating and modifying data, as well as simplifying reporting and auditing processes.

Experts point out that financial institutions will significantly reduce costs when using blockchain, explaining that blockchain’s ability to simplify clearing and settlement directly translates into process cost savings. More broadly, blockchain helps businesses cut costs by eliminating the middlemen — vendors and third-party providers — that traditionally provide the processing that blockchain can do.

By eliminating intermediaries and replacing remaining manual processes in transactions, blockchain can process transactions faster than traditional methods. In some cases, blockchain can process transactions in seconds or less. However, times may vary.

How quickly a blockchain-based system can process transactions depends on a variety of factors, such as the size of each data block and network traffic. Nonetheless, experts have concluded that blockchain generally outperforms other processes and technologies in terms of speed. In one of the most prominent applications of blockchain, Walmart used the technology to track the origin of mango slices in seconds—a process that previously took seven days.

Walmart’s use of blockchain isn’t just about speed; it’s also about the ability to trace the origins of these mangoes and other products. This allows retailers like Walmart to better manage inventory, respond to issues or questions, and confirm the history of their merchandise.

If a specific farm has to recall its products due to contamination, retailers using blockchain can identify and remove the products from that specific farm while keeping the remainderProducts for sale. According to experts, blockchain can help trace the origin of various items such as pharmaceuticals to confirm that they are legal as opposed to counterfeit and organic items to confirm that they are indeed organic.

Immutability simply means that a transaction cannot be changed or deleted once it is recorded on the blockchain. On the blockchain, all transactions are timestamped and date-stamped, so there is a permanent record. Therefore, blockchain can be used to track information over time, allowing for safe and reliable auditing of information.

For example, Omar pointed to Sweden's use of blockchain to digitize real estate transactions to track property ownership even as they change hands as an example of this benefit.

Experts say blockchain could enable unprecedented personal control over one’s digital data. "In a world where data is a very valuable commodity, this technology essentially protects the data that belongs to you while allowing you to control it," said Michela Menting, research director at ABI Research.

Personal and Individual organizations can decide what digital data they want to share, with whom and for how long, and enforce restrictions through blockchain-enabled smart contracts.

Leaders across multiple industries are exploring and implementing blockchain-based systems to solve tough problems and improve longstanding cumbersome practices. Field cited the use of blockchain to verify job seeker resume information as an example of such innovation. Research consistently shows that a large percentage of people falsify their resumes, leaving hiring managers with the time-consuming task of manually verifying information.

But a pilot program that allows participating universities to put data about their graduates and degrees awarded on the blockchain, which can then be accessed by authorized hiring managers, could help address both Question - Get to know the truth and get to the truth quickly and efficiently.

Executives need to carefully consider where they make blockchain investments, experts say.

They emphasize that the real value of blockchain lies in its use in areas where traditional databases do not work and where there is no central control or trust.

“If there’s a high level of trust, blockchain has no problems to solve. But the less visibility you have or the possibility of corruption, that’s where you have a bigger use case. That’s what blockchain Where chain becomes the solution,” Omar said.

Blockchain-based applications could also be paired with artificial intelligence, machine learning or some other decision-making layer, he said.

However, experts still believe that blockchain will bring disruption and business transformation—even if the revolution doesn’t happen anytime soon.

It is important to understand that around blocksThere's a lot of hype about blockchain, and while it's revolutionary in theory, it's not going to change society today," Mentin said. "Maybe it will be there 10 to 20 years from now, but it's not a short-term technology. ”

4. Advantages of blockchain technology

1. Decentralization

Due to the use of distributed computing and storage, there is no centralized hardware or Management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.

2. Openness

The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the entire system information is highly transparent. .

3. Autonomy

The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to trust each other. The free and safe exchange of data in an environment changes trust in "people" to trust in machines, and any human intervention has no effect.

4. Anonymity

Due to The exchange between nodes follows a fixed algorithm, and the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to disclose its identity to make the other party trust itself. The accumulation is very helpful.

Outstanding advantages:

Information cannot be tampered

Once the information is verified and added to the blockchain, it will be stored permanently , unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high.

(4) Advantages of developing your own blockchain Extended reading:

Blockchain originated from Bitcoin, two weeks after the collapse of Lehman Brothers, which marked the starting point of the last financial crisis, in 2008 On November 1, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on the technology based on P2P network technology, encryption technology, timestamp technology, and blockchain. The architectural concept of electronic cash system based on technology, etc., marked the birth of Bitcoin.

Two months later, the theory entered practice. On January 3, 2009, the first Bitcoin with serial number 0 was created. The genesis block was born. A few days later, the block with serial number 1 appeared on January 9, 2009, and was connected to the genesis block with serial number 0 to form a chain, marking the birth of the blockchain.

In recent years, the world's attitude towards Bitcoin has been ups and downs, but blockchain technology, one of the underlying technologies of Bitcoin, has received increasing attention. In the process of the formation of Bitcoin, blocks are storage units one by one, recording All communication information of each block node within a certain period of time.

Between each blockThe chain is realized through random hashing (also called hash algorithm). The latter block contains the hash value of the previous block. With the expansion of information exchange, one block and one block are continued one after another, forming The result is called blockchain [3].

5. Where are the advantages of blockchain technology more prominent

Technical advantages of blockchain ① Data cannot be tampered with, ② Distribution ③ Anonymity ④ Network consensus
① Data cannot be tampered with. Each node stores a copy of the data on the blockchain network. If the data on that node is modified, then the data will be lost. Without recognition by the entire blockchain network, the modified data cannot be verified. This feature of cruise ships can be applied in many fields, such as business data in the financial industry, company government affairs data, audit data, etc. These industries have strict anti-tampering requirements for data.
②, distributed storage and traditional software systems are all managed by a single centralized server. Full consideration must be given to data backup, database clusters, etc., but also Data loss will still occur and data security cannot be well guaranteed. In the blockchain system, each running node has a complete copy of the data and can independently retrieve data, which greatly increases the security of the entire system. Reliability, data between nodes can be synchronized. This distributed structure is very suitable for public service software, and can also be applied to game servers to improve the overall experience of the game. It also has good data security.
③Anonymity. Some traditional account registrations require a user name to be bound to a mobile phone number. Some also require a real name in order to improve the user's identity. Registration. Currently, almost all blockchain products use "address" to identify users. This address is usually a garbled string. The address is usually converted through a public secret key algorithm. Blockchain The data on the website are all open and transparent, but you don’t know who the operator is behind it. This ensures the security of the user’s information to a large extent. This advantage can be used in payment and settlement. Game account protection, etc.
④Network consensus. Many things in our lives require both parties to reach a consensus. Both parties need to sign when signing a contract, and some things require lawyers and notarization, so the whole process changes. It is very complex. Each node in the blockchain system independently verifies the contract and reaches a consensus together. If this mechanism is applied to business, financial, government affairs and other fields, it can greatly improve efficiency.
District There are many application scenarios for blockchain. We can combine the technical characteristics of blockchain to think about its applications in various fields.

6. Three major advantages of blockchain

Blockchain not only records past and present transactions, but can also better solve many problems. For example, it can be used to register copyrights, whether they are physical products or other forms of products.Taste. Registering copyright in the blockchain will have the following benefits.

1. No geographical restrictions

We can think of the blockchain as a decentralized copyright registration platform. In the blockchain, there are no geographical restrictions, and the registered copyright information is displayed in front of us in mathematical form. The advantage of this is that the copyright owner does not need to go through complex registrations in the jurisdiction. This greatly reduces the cost of intellectual property protection and can also reduce the cost of combating piracy. Moreover, the traditional copyright registration method is easily affected by uncontrollable external factors. The registered data may be lost, damaged, tampered with, etc. Once these problems occur, it will become difficult for copyright owners to protect their rights and interests. However, the copyright registration data is stored on the blockchain. Based on the nature of decentralization, each node can back up the copyright registration data. Even if uncontrollable factors occur, the data can be retrieved. Therefore, compared with traditional copyright registration, using blockchain-level copyright will undoubtedly be safer.

2. Lower cost

With the development of social networks, a large number of works with copyright information are published on the Internet. These works are registered under the traditional copyright registration model. , the economic and time costs of copyright protection are too high. But using blockchain, you can register and prove the copyright of your creations anytime and anywhere. In the blockchain, when you upload your creation as soon as possible, the blockchain can record when and where you created it, which can directly prove that you are the copyright owner of the creation. And this data cannot be tampered with. You can do copyright registration certificates for your articles, you can do copyright registration certificates for your photos, anything you think is necessary can be used as cheap copyright registration certificates.

3. More flexible licensing conditions

Use blockchain to prove copyright registration. It may set off a huge wave in global intellectual property protection. There will be more flexible forms for copyright licensing and transfer. Just like current anti-virus software, it has different licensing terms for individual users and corporate users. And all this in the blockchain, when intellectual property consumption is combined with smart contracts, there will be more and more flexible automated agreement licenses to meet the needs of users and sellers. Achieve the goal of mutual benefit and win-win results.

When the cost of copyright registration certificates becomes lower and lower, it is likely that a huge intellectual property trading market will be born. Information can be made valuable, and value can be attributed. Using blockchain to prove copyright registration may realize the ideal of making piracy unable to survive.

Technology always comes firstIt depends on the development of law, but law can always adapt to the development of technology.

7. The advantages of blockchain technology

The main reason is that there is no need to change the data. This is the biggest advantage.
The blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.
Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of blockchain

8. What are the advantages of blockchain technology

Many friends have come recently 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 okay to invest in real estate and wait for appreciation; invest in mature markets such as stocks and bonds. Isn’t it possible? Why invest in the newly emerging blockchain? What is the investment value of blockchain? Waiting for a series of questions, I have made the following summary, which basically summarizes the answers to most related questions:

Blockchain Advantages

Blockchain is regarded as an important part of the fourth industrial revolution. We all know that every industrial revolution will bring about human With the leapfrog progress of productivity, the history of human development is actually the history of one-step progress of 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. The expected market value in 2020 is approximately US$60 billion. It is expected that the value of blockchain in the global market will reach US$20 million in 2024. Blockchain The considerable market prospects 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; traditional market investors often affect their returns due to confusion in the market level, while the programmability of the blockchain makes the market level clear and clear, which can Innovative technologies that change people's lives.
