1. In popular words: if we assume that the database is an account book, reading and writing the database can be regarded as a kind of bookkeeping behavior. The principle of
blockchain technology is to find the fastest and best bookkeeper in a period of time, and then send this page of information of the account book to everyone else in the whole system. This is equivalent to changing all records in the database and sending them to every other node in the whole network. Therefore, blockchain technology is also known as distributed ledger
bitcoin, lightcoin, Ethereum, a smart contract platform, and decent, a distributed content publishing platform, all use blockchain technology.
2. Thank you. Let me give you a serious answer
in fact, the circle effect of blockchain is very obvious, so most people are impetuous, some of them are attentive, and there is very little popular science. I recommend a few here
if you want to watch the video, you can recommend Babbitt's "meow understands blockchain", which is very deep. This is the sentiment of the people who want to watch it. I won't say more about other videos. I think the video of fire coin can also see the words of trust, but it's relatively shallow. I watch it as a kindergarten child
if you are not limited to videos, I think there are several popular science articles to recommend: Jiang Zhuoer's popular science in Zhihu, Gu Qianfeng, lightning, and pan Zhibiao are all great gods. Each category is different. You have to think about it yourself if you want to enter the circle
the things in PS blockchain field are sent here, and there are few people watching them
3. If century Jiayuan wants a mobile phone number, 80% of them are cheaters. This website will try to use some member information to cheat other members' mobile phone numbers. Once it wants a mobile phone number, it will call you and ask if you need matchmaker one-to-one service. My friend signed up for this website and left an old number. The new number was left to a person with good information. However, it didn't take long for this person's information to be closed. It's estimated that my friend's mobile phone number will be hacked. After that, some website staff called to ask whether to provide one-on-one service. My friend has bought a diamond member, As a result, they still cheat others by immoral means. So don't leave any numbers.
