1. There is also anonymity, and now there are smart contracts. Both sides of the transaction specify the content of the contract, and the transaction is completed automatically when it reaches the standard

2. It's a coincidence that I happened to study in the hashton blockchain training institution recently. The characteristics of blockchain are tamper proof, distributed, consensus mechanism and smart contract. In the future, we can help customers solve the problem of business trust through chain reform technology.
3. Hello, we are Shanghai wanglian Information Technology Co., Ltd. compared with traditional technology, blockchain has the property that cannot be tampered with. Vonetracer, the blockchain traceability system launched by our company, adopts a variety of data acquisition methods, one thing and one code, which is true and reliable. It applies instry-leading technology, and the bottom layer adopts the baas platform of blockchain service developed by wangchain. This kind of technical characteristics can ensure that the data is different from the traditional traceability, and the data reliability will be greatly improved.
4. 1、 Decentralization:
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which 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 transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

5. 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, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high.
6. [puzzle] gold miner Chinese version
new gold digger's Chinese version...
game props: press the key to start pulling gold. The red bomb means to pull something you don't want. Press the "↑" key ~ to blow up the thing you pull yourself. The yellow bottle with three forks is strong water. It's a little faster when recycling the rope, It only takes effect in one round. The book "rocks" on it means that if you collect stones, you can sell them at a higher price than usual! 11 pieces of small stones can sell 33 pieces, which is also effective in the same game. The thing in the yellow bottle is brick oil, which will make bricks appreciate. 600 pieces of bricks will sell to 900! It's also the lucky grass that takes effect in the first round. If you use it, you can increase your lucky degree and pull it to "?" If you buy a small bag, you may become very strong, or you may get some of the above items, and sometimes even the price of stones will rise!

7. The analysis of Chongqing jinwowo network is as follows:
based on the characteristics of decentralization, even if the blockchain is seriously attacked by hackers, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
this is a distributed data storage based on blockchain, because there is no centralized management center, so that even if a node in the blockchain system is attacked or tampered, the healthy operation of the whole network will not be affected
because the rights and obligations of all nodes are equal, and the activities will be supervised by the whole network. At the same time, each of these nodes has the ability to vote with computing power, which ensures that the result recognized is the result recognized by more than half of the nodes.
