1. 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.
2. The distributed architecture and tamper proof features of blockchain technology help to solve the problems of bill authenticity and information opacity. When participants need to check whether the bill has been tampered or transferred, blockchain can provide indisputable proof of consistency
digital currency also makes use of this feature of blockchain. Puyin is a kind of tea standard digital currency developed based on blockchain technology.

Blockchain is a kind of chain data structure that combines data blocks in order according to the time sequence, and it can't be tampered and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data< br />
4. [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!

5. Press the "s" key on the keyboard and the "↓" of the cursor movement key, press the "s" key with the left hand and "↓" with the right hand, and it will be easier to score with both hands.
6. Jinwowo analyzes the security of data when using blockchain Technology: blockchain technology is a kind of technology that supports decentralization in a trustless network environment
it can ensure the security of the communication network of the application system running on the chain by means of digital signature, and use hash chain technology to ensure that the written data can not be changed.

7. Blockchain can encrypt and store certificates to ensure data security
the Internet makes our life more convenient, but it also brings a series of problems and challenges about data security. Under the wave of digitalization, data security may become the core competitiveness, and under the momentum of vigorously developing blockchain in our country, it will become the general trend for blockchain to ensure data security
through self-developed blockchain technology and invention patents, yibaoquan has launched "blockchain + full evidence chain + preservation chain", which effectively ensures data security and judicial compliance. Through DES, SHA512 and other encryption algorithms, as well as time stamp service and pbft consensus algorithm, the work data is encrypted to help users encrypt and store the electronic data on the blockchain at the first time, fully guaranteeing the originality of the data stored in the blockchain and effectively preventing tampering.

8. In the blockchain network, data does not exist in a certain place. When a legal data is written, the data will be stored on 51% of the nodes in the network at the same time. Therefore, once the data is written, it cannot be tampered with, unless you have the ability to tamper with 51% of the nodes at the same time, which is almost impossible.
