『一』What is the smart contract in Jinwowo blockchain technology?

Chongqing Jinwowo analyzes the smart contracts in blockchain technology as follows:
Smart contract is a contract that uses computer language instead of legal language to record terms.
Smart contracts can be automatically executed by a computing system. If the blockchain is a database, smart contracts are the application layers that enable blockchain technology to be applied to reality.
Contracts in the traditional sense are generally not directly related to the computer code that executes the contents of the contract. Paper contracts are in most cases archived, while software enforces the terms of the contract written in computer code.
Potential benefits of smart contracts include reducing the costs of contract signing, execution and supervision

『二』Understanding blockchain, what is a smart contract

Smart contracts are a A contract that does not require a third party such as a notary or public official to verify, facilitate or enforce!

Literally means you can conduct fast, reliable and trustworthy transactions with any third party, without the constraints of ordinary contracts

Healthcare

Who has access to my patient data? Is my digital patient record safe? and many other issues arise from having digital patient records. As we learned, if only a limited number of people need access for a limited time, keep your profile with you at all times and only have access if you allow doctors access.

Highly regulated, such as drug storage and distribution.

『三』 What are the current obvious shortcomings of smart contracts in blockchain technology?

“The working theory of smart contracts is late. An important reason why it has not been realized is the lack of digital systems and technologies that can support programmable contracts. The emergence of blockchain technology solves this problem. It can not only support programmable contracts, but also be decentralized, non-tamperable, and process transparent. Advantages such as traceability are naturally suitable for smart contracts. Therefore, it can also be said that smart contracts are one of the characteristics of blockchain technology."
Smart contracts based on blockchain technology can not only take advantage of the cost efficiency of smart contracts advantages, and can avoid malicious behavior from interfering with the normal execution of the contract. Smart contracts are written into the blockchain in digital form, and the characteristics of the blockchain technology ensure that the entire process of storage, reading, and execution is transparent, traceable, and cannot be tampered with. At the same time, a state machine system is built using the blockchain’s own consensus algorithm to enable smart contracts to run efficiently.

『四』What are the advantages of blockchain

The advantages of blockchain are mainly reflected in the following points:
1. Decentralization
Due to the use In distributed computing and storage, there is no centralized hardware or management organization. The rights and obligations of any node are equal. The data blocks in the system are shared by nodes with maintenance functions in the entire system.maintain.
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 query the blockchain through the public interface. Data and development 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 exchange data freely and securely in a trustless environment. , so that trust in "people" is changed to trust in machines, and any human intervention has no effect.
4. 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, otherwise the database will not be modified on a single node. Modifications are invalid, so the data stability and reliability of the blockchain are extremely high.
5. 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 Making the other party trust you by disclosing your identity is very helpful for the accumulation of credit.

As above, there are many applications of blockchain now, and it has been applied to various fields, such as GSN in social banking. GSN can effectively reduce financial risks by applying blockchain technology to finance. Because the credit management level of participating market entities will be improved due to the application of blockchain technology, on the other hand, it will also be conducive to the construction and improvement of the entire social credit system.

Secondly, GSN can transform traditional credit management based on experience and system design into a blockchain management model supported by heavy technical means. By introducing GSN, this advanced information management technology, it will help improve credit management. The technological content improves the accuracy and rigor of management.

Finally, GSN can effectively reduce the current high cost of social credit, open up the information islands between credit information, and effectively prevent the loss, leakage or tampering of social credit information. Blockchain has a wider range of application scenarios in building a social credit trust system and promoting digital inclusive credit reporting.

『Wu』What is a smart contract in blockchain technology

A smart contract can be simply understood as a piece of code written on the blockchain, driven by events and with dynamic status , is recognized by multiple parties, and can automatically process information on the chain according to preset conditions. Once an event triggers the terms in the contract, the code will be automatically executed. The biggest advantage of smart contracts is to use program algorithms to arbitrate and execute contracts on behalf of humans.
Smart contracts are contracts that use computer language instead of legal language to record terms. Once written, they can be trusted by users. The terms of the contract cannot be changed, so the contract is immutable. The program will be executed if it meets the conditions.No artificial interference shall be carried out in accordance with the law to ensure absolute fairness and justice.
3 technical characteristics of smart contracts
●Data transparency
All data on the blockchain is open and transparent, so the data processing of smart contracts is also open and transparent, and any party can run it can view its code and data.
●Cannot be tampered
All data in the blockchain itself cannot be tampered with, so the smart contract code deployed on the blockchain and the data generated by its operation are also non-tamperable. Nodes running smart contracts do not have to worry about other Nodes maliciously modify code and data.
●Permanent operation
The nodes supporting the blockchain network often reach hundreds or even thousands. The failure of some nodes will not cause the smart contract to stop. Its reliability is theoretically close to permanent operation. In this way This ensures that smart contracts can be as valid as paper contracts at all times.

『Lu』 The essential characteristics of blockchain smart contracts

The essential characteristics of blockchain smart contracts: decentralization.

Some of the main advantages of using smart contracts include greater efficiency when processing documents. This is thanks to its ability to employ a fully automated process that does not require any human involvement, as long as the requirements listed in the smart contract code are met.

The result is that time is saved, costs are reduced, transactions are more accurate and cannot be changed. Additionally, smart contracts remove any third-party interference, further enhancing the decentralization of the network.

(6) Advantages of blockchain smart contracts Extended reading:< br />

Smart contracts can only use digital assets, and problems will arise when connecting real assets and the digital world. Finally and most importantly, smart contracts lack legal supervision and are only subject to the obligations agreed in the code. The lack of legal regulation may lead some users to be wary of transacting online, especially if it is significant.

The advantages of using smart contracts are more efficient processing of transactions, irreversible, secure transactions and fully automated processes. On the other hand, the disadvantages are the lack of legal supervision, human errors and difficulties in implementation.

『撒』What is the role of smart contracts in blockchain technology

Smart contracts make the blockchain more scalable and simpler to implement, thus allowing Ethereum to Fangfang has developed into the largest blockchain development platform at present. For the convenience of understanding, my definition of smart contract is: smart contract is executable code in the blockchain environment.

『8』 This article summarizes the nine major benefits that blockchain technology brings to enterprises

The launch of Bitcoin, the first application of blockchain in 2009, changed the blockchain from Theoretical applications turned into real-world applications, 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-knownCompanies, 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.

In addition, data on the blockchain is stored in computer networks, 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 efficiency in processing transactions, and reduce manual tasks such as aggregating and modifying data, as well as streamlining 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 products from that specific farm while selling their remaining products. 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. Michela Menting, Research Director at ABI Research: "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."

Individuals and individual organizations can decide they want to share Which digital data is shared, with whom and for how long, with restrictions enforced 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’s important to understand that there’s a lot of hype around blockchain, and while it’s revolutionary in theory, it’s not going to change society today,” Mentin said. “Maybe from now on It will appear in 10 to 20 years, but this is not a short-term technology. ”
