区块链消费的优势有哪些,区块链消费的优势和劣势

A. Where are the advantages of blockchain technology more prominent

Technical advantages of blockchain ① Data cannot be tampered with, ② Distributed storage 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 this data will not be available to the entire blockchain network. Admittedly, the modified data cannot be verified. This feature of cruise ships can be applied to many fields, such as business data in the financial industry, company government affairs data, audit data, etc. These industries all have strict data requirements. Tamper resistance requirements.
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 data loss will still occur and cannot be guaranteed. Data security. In the blockchain system, each running node has a complete copy of the data and can independently retrieve data, which greatly increases the reliability of the entire system. Data between nodes can also 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 and also has good data security.
③Anonymity. Some traditional account registrations require a username to be bound to a mobile phone number. Some also require a real-name registration in order to improve the user's identity. At present, 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. The address on the blockchain The data is open and transparent, but you don’t know who the operator is behind it, so this ensures the security of the user’s information to a large extent. This advantage can be used in payment and settlement, game accounts Protection, etc.
④ Network consensus. Many things in our lives require both parties to reach a consensus. Both parties need to sign a contract, and some things require lawyers and notarization, so the whole process becomes very complicated. It is extremely complex. Each node in the blockchain system independently verifies the contract and reaches a consensus together. This mechanism is applied to business. In fields such as finance and government affairs, efficiency can be greatly improved.
There are many application scenarios for blockchain. We can combine the technical characteristics of blockchain to think about its applications in various fields.

B. Three major advantages of blockchain

Blockchain not only records past and present transactions, but can also better solve many problems, such as registration Copyright, whether in the form of a physical product or otherwise. Registering copyright in the blockchain will have the following benefits.

1. No geographical restrictions

We can blockLian is regarded 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 precedes the development of law, but law can always adapt to the development of technology.

C. Advantages of blockchain technology

1. Decentralization

Due to the use of distributed computing and storage, there is no centralizationThe 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 and anyone can The interface queries blockchain data and develops related applications, 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 trustlessly The free and safe exchange of data in the environment changes trust in "people" to trust in machines, and any human intervention has no effect.

4. Anonymity

Since the exchange between nodes follows a fixed algorithm, 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, which is very helpful for the accumulation of credit.

Outstanding advantages:

Information cannot be tampered

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

(3) Advantages of blockchain consumption Extended reading:

Blockchain originated from Bitcoin, which marked the starting point of the last financial crisis. Two weeks after the collapse of Mann Brothers, on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", explaining the encryption technology based on P2P network technology. Technology, timestamp technology, blockchain technology, etc. are the architectural concepts of electronic cash systems, which marks the birth of Bitcoin.

Two months later, the theory came into practice. On January 3, 2009, the first Bitcoin genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block 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 formation process of Bitcoin, blocks are storage units one by one, recording all communication information of each block node within a certain period of time.

The links between each block are 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, a Blocks are continued one after another, and the result is called a blockchain [3].

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

The blockchain ecology can be seen from the followingFrom 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.

E. The advantages of blockchain technology

The main thing 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 mechanism and data verification mechanism, etc.; the consensus layer mainly encapsulates various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; contracts The layer mainly encapsulates various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain

F. Blockchain Technology Advantages

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 accounts.In the book-keeping system, the central account book plays the role of information custodian. Each transaction requires the endorsement of a third-party intermediary or trust institution. This is a centralized transaction 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.

G. What are the advantages of blockchain technology

Recently, many friends have come to ask questions related to blockchain, such as district What are the specific advantages of blockchain? Why invest in blockchain? What benefits can it bring? Isn’t it okay to invest in real estate and wait for appreciation? Is it not okay to invest in mature markets such as stocks and bonds? Why invest in the newly emerging market? What about blockchain? Does blockchain have any investment value? Waiting for a series of questions, I have made the following summary, which basically summarizes the answers to most related questions:

Blockchain is regarded as an important part of the fourth industrial revolution. We all know that every industrial revolution will bring about leaps and bounds in human productivity. The history of human development In fact, it is a history of productivity progress

It can be roughly summarized in the following four aspects:

1. Blockchain has good market prospects; as an emerging technology, blockchain is included by investors Many professionals, including Blockchain, have recognized that the expected market value in 2020 is approximately US$60 billion, and the value of blockchain in the global market is expected to reach US$20 million in 2024. 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. This eliminates counterfeiting and avoids losses caused by third-party credit issues.Provide 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.

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!

H. What are blockchain + e-commerce? Advantages

Online shopping is convenient, complete, and saves time and effort. It has become an unchangeable way of life for people and has brought a lot of convenience, but there are also some problems that trouble consumers.

Counterfeit goods are rampant and quality issues cannot be monitored

Counterfeit goods are an online and offline economic phenomenon. However, after being spread through Internet platforms, online fakes have been questioned, and sometimes the Internet is even called a "counterfeit goods distribution center."

For e-commerce companies eager to operate normally, the Internet is both a prosperous place and a sad place. Many e-commerce companies have suffered serious damage to their reputation.

In response to this phenomenon, we use blockchain technology to develop a decentralized traceability certification mall. All products in the mall will display the traceability information of the product on the product details page, from the origin of the raw materials, raw material batches, to the production and processing process.

The traceability information of dealers and distributors, including logistics, will be fully displayed on the product details page. Consumers can see all the information about this product just like browsing the product details page normally. . Consumers can supervise products from the source, prevent fakes, and verify the authenticity of products.

Credit crisis

The problem of consumer trust behind selling fake goods. Once trust declines, it will not affect one or two online stores, but the entire e-commerce industry faces an existential crisis. Not only that, in recent years, it is not uncommon for many consumers to engage in dishonest behaviors such as returns of inferior goods, overbearing clauses, and rising prices first and then falling prices. There are also many merchants who try to falsify their products, boost sales and praise, shatter the glass, and confuse consumers.

On the surface, the phenomenon of e-commerce billing is a problem of imperfect laws and regulations, but fundamentally it is an issue of unscientific operating rules of e-commerce platforms, especially e-commerce or product display and sorting. the rule of. Using a unique algorithm, we focus on product quality and service quality, while integrating sales and reputation.

At the same time, we use intelligent detection mechanisms to punish merchants who fake orders. Merchants do not need to spend a lot of money to brush bills, which avoids unfair competition in brushing bills and maximizes theThe overall interests of the community are ensured.

Operating costs remain high

The cost of opening a store on a traditional e-commerce platform is getting higher and higher. Excluding product costs, traffic drainage, new production, filming and production, and platform deductions, merchants are increasingly saying that they can’t bear it.

Thanks to the decentralized model, blockchain and smart contracts, the use of quality and security chains and smart contracts, the use of cryptocurrencies as payment solutions, taking into account security, low cost and fast payment processing speed.

The combination of blockchain and e-commerce has the following advantages:

Improve operational efficiency: Use the technical advantages of blockchain to simplify operations and improve efficiency. Smart contracts are used to regulate intermediaries, such as logistics and payment processing partners, but also to monitor sellers and consumers.

The smart contract retains records of transactions and evaluations between all sellers and buyers in the quality safety chain, ensuring that all reviews come from customers who actually purchased the product. Transaction records and assessments must not be tampered with.

Trust and Transparency: Another important advantage of blockchain and e-commerce is that it can increase the transparency of transactions, thereby promoting trust. Every transaction is recorded on the shared ledger and cannot be modified by anyone.

It provides high security, enhanced visibility, and faster processing making every transaction trustworthy, reliable and transparent.

Reliable data security: Whether it is centralized storage or cloud storage, data storage is always a vulnerable place and can easily fall into weak encryption. Even the best encryption systems can be hacked.

Blockchain technology is used to provide a decentralized ecosystem to ensure data security on the chain.

Combined with blockchain technology, it breaks the traditional e-commerce benefit distribution system, breaks the traditional e-commerce anti-counterfeiting model, and creates a new "decentralized" trusted mall and blockchain through individuals, merchants, and platforms. Community.

I. What are the major advantages of blockchain application technology?

Jinwowo analyzes the major advantages of blockchain technology application:
1. Security Greatly improved;
2. Records cannot be tampered with;
3. Solve intermediary trust issues;
4. Improve efficiency and reduce costs
