As for this question, I suggest you go to lobby the community to have a look (web link), where there are big guys and big V to answer for you. Here I share with you an article by Mr. Ruan Yifeng, which should be able to answer your questions

I. what is the essence of blockchain? In a word, it is a special distributed database

the current rule is that new nodes always use the longest blockchain. If there is a fork in the blockchain, we will see which branch is behind the fork point and reach six new blocks first (called & quot; Six confirmations. According to the calculation of a block in 10 minutes, it can be confirmed in one hour

since the generation speed of new blocks is determined by computing power, this rule means that the branch with most computing power is the authentic blockchain

9. As an unmanaged distributed database, blockchain has been running for 8 years since 2009, and there is no big problem. This proves that it is feasible

However, in order to ensure the reliability of data, blockchain has its own costs. One is efficiency. When data is written to the blockchain, it takes at least ten minutes. If all nodes synchronize data, it takes more time; The second is energy consumption. The generation of blocks requires countless meaningless calculations by miners, which is very energy consuming

therefore, the application scenarios of blockchain are very limited

there is no management authority trusted by all members

the data written by

does not require real-time use of

the benefits of mining can make up for its own costs

if the above conditions cannot be met, then the traditional database is a better solution

at present, the biggest application scenario (and possibly the only one) of blockchain is cryptocurrency represented by bitcoin
