区块链系统开发的效果,区块链系统应用开发

A. 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

B. Advantages of blockchain technology

1. Decentralization:< br />Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, through distributed accounting and storage, each node realizes information self-verification, transmission and manage. 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.

C. 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; 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!

D. Advantages of Blockchain Technology

Sharing source:

“Blockchain is a shared distributed database technology, and its advantages are mainly reflected in distributed decentralization,There are three aspects of trustless system and immutable and encrypted 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. Compared with the traditional situationOn the contrary, 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.

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

Jinwowo analyzes the application of blockchain technology again Big advantages:
1. Security is greatly improved;
2. Records cannot be tampered with;
3. Solving intermediary trust issues;
4. Improving efficiency and reducing costs

F. 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 it is a physical product or another form of product. 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 it for your photosCopyright registration certificate, anything you think is necessary can be used to make a cheap copyright registration certificate.

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.

G. 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< br />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 recognized by the entire blockchain network. , 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, government affairs data of companies, audit data, etc. These industries have strict anti-tampering of data. Require.
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 All 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 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. Then the whole process becomes very complicated. In the blockchain Each node in the 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.
