What is blockchain learning duck
this is a passage in Alibaba's documentary dreamer. When ps: is repeated many times, it can explain the term "third parties" very well. This is also the beginning of Taobao and Alipay's birth. In other words, at that time, Ali was forced to act as a "third party" because no company could play such a role, so Ali became a center of trust. Businesses and users chose to give money to Ali because of "trust". But what if Ali absconds with money (though impossible...) or if the financial operator has problems (after all, it's human...)? If only there was a machine or a "super system" to do these things! Today, more than ten years after the replacement of Internet technology, blockchain appears in front of us, right! It's the super system;! A machine of trust
with blockchain, things start to change
traditional centralized mode:
decentralized mode under blockchain network:
in decentralized network, each user can be directly contacted without any third party's participation, and the transfer between users is like hand-in-hand cash, which is why bitcoin is called "e-cash"
well, now that a has transferred the money to B, who will charge the account? Alipay has helped me keep account of accounts, which will be unified in Alipay backstage system. In order to make all the transactions of the users recorded and the accounts are correct, Alipay will make great efforts to this end. Look at Alipay's initial
1000 bills per day. Artificial reconciliation is already very painful. With the volume of Alipay now, there are less than hundreds of thousands of bills per day, even if the system reconciliation is unavoidable, and it is necessary to pay the corresponding manpower and material resources to maintain this very complex revenue and expenditure clearing system. Having said so much, how does the blockchain reconcile? The answer is: no! There is no need for reconciliation and zero clearing in the blockchain network, because every node in the blockchain (a computer or a user) has its own account book, which is updated in real time. Any transaction in the blockchain network will be recorded in your own account book. Yes, you also have other people's accounts, But you don't know who this person is, because they all look like this:

For this year's computer development, I believe everyone will not be surprised, because the growth of graphics card is too terrible, and the terror is not a period of time, but lasted for as long as a year. This time, people will be puzzled why bitcoin mining consumes more electricity than Sweden in one year? In fact, this matter is very easy to explain. When digging bitcoin, we need to work at full load. That is to say, all computers are overloaded. It must be very power consuming. Let's make a detailed analysis
1: computer parts work at full load:
but now the price of bitcoin has also dropped. I believe the price of bitcoin will return to normal around next year, and the display card and other parts will return to normal at that time. Now the graphics card is too expensive, we as an ordinary person want to buy a good graphics card to play games are more difficult
