Ⅰ How blockchain is applied to digital art

The core applications of blockchain in the art field include provenance verification, authenticity recording,
new media and generation Digital scarcity, fragmented and shared ownership, and new forms of copyright recording in sexual art.
Smart contracts based on Ethereum also bring more investment options - introducing innovative intellectual property structures.
In traditional art, in order to prepare for art exhibitions, galleries need to spend a lot of time researching the provenance of works.
The cost of review is included in the gallery’s markup fee structure such as commissions. But blockchain technology brings far more than just cost reduction.
Its verification of provenance can even determine whether a work can be successfully sold.
In the future, blockchain can solve the problem of lack of paper records and the need for proof of ownership,
fully leveraging the potential power of immutable and decentralized records. If a blockchain database becomes a property rights registry that
can prove legal ownership, then legal ownership of a work will be inseparable from blockchain proof of provenance.

II What are the applications of blockchain industry

Take the tourism industry as an example. Blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, credit consumption management, Tracking pilots' professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumer points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.

III What are the applications of blockchain technology

Developing Ethereum Cat based on Ethereum, is this an application? It is a bit interesting, and there is also NetEase Planet. For traceability, I have snapped up the Orange Chain made by China Enterprise Tongbao Blockchain, which is used for blockchain traceability records on Orange.

IV Application aspects of blockchain

The main application scope of blockchain includes: digital currency, transaction settlement of financial assets, digital government affairs, certificate deposit and anti-counterfeiting data services and other fields. Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. BlocksThe characteristics of chain technology, such as anonymity, decentralization, openness, transparency, and non-tamperability, make it highly favored by enterprises and has been applied more widely.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. The non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server.Due to the security of the equipment and the opacity of the centralized server, it is difficult to effectively protect users’ privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for various participating entities to accurately understand the real-time status and existing problems of related matters, affecting the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with and can ensure the transparency of information nature, forming a shared trust among competitors who do not trust each other.Only. And it can arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

IV What is blockchain? In addition to food traceability, what other common applications does blockchain have?

< p>Save production and distributor costs, and use blockchain technology and the Internet of Things to realize automated data collection and storage, reducing labor investment and other equipment investment; in addition, the application of blockchain technology and the Internet of Things can help manufacturers and Distributors reduce various expenditures and reduce the prices of agricultural products, thereby achieving customer profitability.

The key to blockchain technology is a distributed digital ledger that can store all types of information, including cryptocurrency transactions, NFT usage rights, and DeFi blocks chain.

Although any traditional database system can store this information, digital currency is unique in its complete blockchain technology. In contrast to systems maintained in core organizations by central administrators (such as Excel spreadsheets or bank database systems), blockchain databases have many identical copies stored on multiple computers that exist on the network, but these independent electronic Computers are called connection points.

The name "blockchain technology" is not a whim. Data ledgers are generally described as "chains" composed of separate "data blocks". When new data is imported into the network, a new "block" is created and added to the "chain," which involves all nodes updating their versions of the blockchain ledger so that they are the same.
