⑵ What are the application scopes of the third-generation blockchain DAG for the Internet of Things

DAG is also a directed acyclic graph. There is no concept of blocks in it. The entire flow chart It is composed of transactions one after another. The advantage is that it can save the process of block generation and packaging. The advantages are faster speed, no transaction fees and no need for mining.
IOTA uses DAG technology to create a blockchain rental platform for living planet, which will also be developed based on IOTA. Ideally, the larger the network, the faster IOTA’s transaction confirmations and the more secure the network. Living Planet uses this to realize the interconnection of things with smart terminals such as smart door locks, routers, cameras, etc. needed for renting a house.

⑶ What kind of technology implementation will be used to rent a house on the blockchain to live on the planet?

The IOT service of the living planet platform has designed a revolutionary new transaction settlement and data transfer layer. It is based on a new type of distributed ledger DAG. DAG can overcome the inefficiencies in existing blockchain designs and create a new method for reaching consensus in decentralized P2P systems. For the first time, transfers via DAG do not require payment of fees. This means that no matter how small the payment is, it can be completed through DAG.

⑷ How to apply it in the real estate industryBlockchain technology

1. Financing through asset tokenization, but it is not yet compliant in China;
2. Realizing cost management through blockchain technology can make quality traceable and contracts Cannot be tampered with;
3. Disintermediation of the transaction link is achieved through the chain, but it is difficult to achieve it in one step. It starts with weak intermediation and then gradually evolves to disintermediation;
4. For the rental market , consumer rewards can be carried out through token design.

⑸ What is the new trend of chain reform to guide chain reform solutions

In fact, the working principle of blockchain is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computers The new combination application model of technology uses smart, open, traceable, and unchangeable contract technology. The development of chain reform technology solves the problem of trust, allowing people to establish a more direct relationship with applications under the Internet. of trust. Because in traditional economic activities, the source of trust is mainly maintained from aspects such as authority and contracts. However, relying solely on trust in people or organizations is risky, and may even inevitably lead to breach of trust, leading to cooperation. Both sides were severely affected. Currently, blockchain is a key direction for future development planning. After the General Secretary mentioned blockchain in the 18th collective study session of the Political Bureau of the CPC Central Committee, the word became a hot topic among the people. Whether it’s the uncle or aunt at the next table, or the office workers on the subway, or even those born after 2000 are talking about blockchain. The "chain reform" plan proposed by Bilian Technology coincides with the policy concept and complements each other. It focuses on helping domestic small and medium-sized enterprises to transition out of the sluggish market environment, create digital markets and contract trading systems, and reduce corporate operating costs and market risks, and gradually realize the profitability of enterprises.

1. In terms of business model, open up the inside of the enterprise (shareholders, employees) and the outside of the enterprise (channels, users), make them a community of interests, and create an enterprise with no shortage of funds, no shortage of customers, A perfect organization and ecology that has no shortage of employees;

2. At the technical level, create a trusting mechanism so that the technical foundation for collaborative collaboration with zero cost can be implemented;

/> 3. At the financial level, rely on trustworthy foundations to disintermediate and realize the rapid flow of use value at zero cost;

4. Economically, various value islands can be opened up to create value ecology. Introduce blockchain technology to build a "smart + credit" urban service platform, and apply blockchain technology to the rental field. As an emerging industry, blockchain has changed the central control model of the traditional Internet. Since the development of blockchain, blockchain has gradually shifted from technical research to application exploration. Blockchain technology plays an important role in driving regional digital transformation and promoting high-quality economic development.

In fact, Bilian Technology has become a pioneer in this regard, finding typical implementation scenarios and using blockchain technology to transform traditional fields.upgrade. Using the advantages of blockchain technology, Bilian Technology has launched practical solutions in the fields of supply chain management, asset management, e-commerce, agricultural product (food) traceability, electronic signatures, electronic invoices, online game platforms, traceability and other fields. By relying on blockchain technology to digitalize and tokenize enterprises, the production efficiency and management efficiency of enterprises are improved, and comprehensive assistance is given to traditional enterprises to implement blockchain.

So what does blockchain have to do with ordinary people like us?

In the future, we can record identity information on the blockchain system. This way you don't have to worry about identity theft, and you can also ensure that your identity information is completely correct, and you no longer have to face the embarrassment of proving "my mother is my mother."

Moreover, our medical information can also be put on the blockchain. Every hospital can see your admission information, so there is no need to waste extra time and money on repeated visits. With blockchain, food safety can also be guaranteed. A bag of rice is clearly recorded on the blockchain from sowing and fertilization, wind direction and rainfall in the planting area, to supervision by the person in charge, etc. Due to the non-tamperable nature of the blockchain, the source of the rice can be guaranteed to be authentic and reliable, completely preventing spoilage, Consumption of genetically modified rice.

There is also the issue of copyright. Once copyright information is recorded on the blockchain, it cannot be tampered with or stolen at will.

In addition, blockchain can be of great use in various fields such as education, insurance, rentals, etc. As a new technology, blockchain is still in its early stages of development, and there are some malicious smears and opportunistic hypes. Therefore, while we understand this technology, we must also avoid listening to rumors and falling into scams. Learning new knowledge rationally starts with me.

⑹ Multiple types of data are shared on the "chain", online and offline services are coordinated, and blockchain government affairs make things easier

What will happen when "blockchain + government affairs" collide? spark? Mawei Xingang Community in Fuzhou City, Fujian Province uses blockchain technology to solve the pain points of government informatization and launches a "blockchain + community certification" application. "This application can easily realize the electronic issuance of certificates required by enterprises and the masses, promote the transformation from 'reduced certificates' to 'no certificates', let data run instead of people running errands, improve service efficiency, and better serve the people. "Ms. Zhu, a citizen of Fuzhou, said.

Provident funds can be transferred and continued in other places

"Post-90s" Chen Jing joined a new company at the end of last year, and her work location changed from Hangzhou, Zhejiang to Chengdu, Sichuan. If you change your workplace, how can you transfer the previously accumulated housing provident fund to a new account? After consultation, Chen Jing learned that when she searched for “national residence” on her mobile phone, sheThe "National Housing Provident Fund" applet can realize off-site transfer and connection. According to the relevant person in charge of the Ministry of Housing and Urban-Rural Development, the "National Housing Provident Fund" applet will be launched online in October 2021. The Ministry of Housing and Urban-Rural Development has deepened the application of new technologies such as blockchain to facilitate the operation of the applet. A trustworthy data environment has been built to ensure the security of depositors’ information and funds. Thanks to blockchain technology, depositors can transfer housing provident fund accounts and funds across cities through small programs, and no longer need to go to the counter to handle off-site transactions. The transfer and continuation of business greatly shortens the processing time and further facilitates the cross-regional flow of human resources.

Multiple types of data are shared on the "chain", online and offline services are coordinated, and the use of blockchain technology improves government affairs Department efficiency and public satisfaction. For example, Haidian District in Beijing has opened a "Blockchain Zone" on the Haidiantong APP, which can directly handle matters such as public rental housing subsidies and Haidian District high-tech talent training subsidy approval... With the help of blockchain, etc. With the application of new technologies, many government services have realized "one-stop service and full online service".

In addition, Zhuzhou City, Hunan Province has also innovated administrative approval service methods and launched electronic certificate blockchain application scenarios, effectively improving Government data sharing level and business collaboration efficiency; Fuzhou City launched the "Rongcheng on the Chain" plan to explore the use of blockchain technology in four fields including e-government, financial technology, social governance, and people's livelihood security.

Why is blockchain technology favored in the government field? Industry insiders believe that blockchain technology has the characteristics of non-tampering, security, confidentiality and traceability, and is highly suitable for government service needs such as cross-domain data sharing and business collaborative management. Blockchain is actively used Technology can solve problems such as difficulty in data sharing and business collaboration in the process of government services, and improve government management services and overall coordination capabilities.

Effectively assist people's livelihood services

Many places in China are based on regional Blockchain-related management service platforms are frequently launched: In Jiangsu, the country's first idle residential use rights transfer transaction based on blockchain technology was successfully completed. Relying on the provincial information service platform, transaction information can be directly uploaded to the "chain" to store certificates, ensuring that the housing The source is trustworthy and the results are traceable; in Zhejiang, the first intellectual property blockchain public certification platform was officially launched, providing efficient and fast certification services for data assets, original designs and other intellectual property rights; in Yunnan, the province’s market supervision and management The bureau and the Provincial Key Laboratory of Blockchain Application Technology jointly carry out Yunnan Province's blockchain underlying chain food traceability work based on domestically produced independent products, and use blockchain technology to promote the realization of product source traceability, one code to the end, logistics tracking, responsibility identification and credit Evaluation, so that blockchain technology can truly contribute to people’s livelihood services.

Hu Kai, a professor at the School of Computer Science at Beihang University, told this reporter that the current blockchain industry applications are mainly divided into practical applications.The government attaches great importance to guiding the application of blockchain in manufacturing, energy, government affairs, education and other fields.

Active drive at the policy level has allowed blockchain to continue to advance in industries such as judicial evidence storage and transportation and shipping data sharing. In May, the Supreme People's Court issued the "Opinions of the Supreme People's Court on Strengthening the Judicial Application of Blockchain", proposing that by 2025, a blockchain alliance for interoperability and sharing between people's courts and all walks of life should be established to form a relatively complete blockchain judicial system. Field application standard system. In June, the Ministry of Transport issued the "Guidelines for the Construction of an Electronic Platform for Imported Dry Bulk Cargo Entry and Port Business Based on Blockchain" in June, proposing to promote the in-depth integration and development of blockchain technology and the transportation industry.

Let data flow safely and orderly

Hu Kai believes that today, with the rapid development of the digital economy, numbers and data are key elements for future social development, but there are still legal issues behind the data. , interoperability, privacy, security, traceability, storage, transactions and many other complex issues. How to make data flow more securely and orderly? Blockchain technology has broad room for development.

Blockchain technology is accelerating breakthrough applications and playing a role in establishing a trustworthy and secure digital economic order and promoting high-quality economic and social development. The China Academy of Information and Communications Technology released the "Blockchain Infrastructure Research Report (2022)" in July this year, proposing that as the scale of blockchain infrastructure construction continues to expand and operating capabilities continue to increase, blockchain can not only be used in encrypted digital Currency and other scenarios can also be applied in manufacturing, service industries and other fields. Typical application scenarios such as digital collections, data circulation, supply chain finance, and product traceability have emerged.

⑺ What are the characteristics of blockchain?

There are five main technical characteristics of blockchain, namely: decentralization, information cannot be tampered with, openness and transparency, and collective maintenance. , reliable database. It can be used in many aspects, for example, let’s take a rental agency. In the past, the agency had information about the property and the tenants. Moreover, some unscrupulous agents would change the information at will, just to make money in the middle. More agency fees. And if a blockchain is built and applied in the rental field, then the property information will be filled in by the landlord, and the tenant's information will be filled in by the tenant. Note that once the information is filled in, it cannot be changed twice. So this is equivalent to removing the center of intermediary. Of course, we are just talking briefly. In fact, deploying such a blockchain is also very complicated.
