How does blockchain tamper with data

2.

With the rapid development of Internet technology, it has brought us infinite wonderful and convenient life. At the same time, with the continuous improvement of 5g network, container cloud and high-performance storage hardware, data growth has entered an unprecedented stage of development

AR, VR, Internet of things, edge computers and other devices available everywhere generate a continuous stream of data, just like an open water pipe, the data source has been flowing out. The data generated will increase geometrically. At this time, the storage technology of blockchain will be demonstrated. A few years ago, there was an excellent IPFs project in the blockchain storage technology

{rrrrrrr}

yottachain takes the blockchain as the underlying technology and develops a powerful incentive scheme for miners. With 1GB
of space invested by miners, yottachain can generate 5-10gb of storage capacity, which proces the miracle effect that the purchasing power of digital currency obtained by resource suppliers exceeds the resources they supply

There is no doubt that data storage is now in the initial stage of the transformation from centralized storage to distributed storage. When more and more indivials and organizations begin to use blockchain technology to change all aspects of our lives, I believe yottachain will also make greater contributions to our economy in the new era

3. 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.

4. 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.

5. [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!

6. If it is the proof of workload, it can be modified, but it needs to invest a lot of money. For example, if you want to change the block data of bitcoin (such as transferring all bitcoin to your wallet, etc.), it needs to account for 51% of the total network computing power. But with so many miners digging, it is basically impossible to account for 51% of the total network computing power.

7. 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.

8. Yes, it is characterized by distributed data management, which can effectively rece the probability of data tampering by others, and also realize the security management of personal information. This is what the six degree chain has been pushing.
