Taobao with blockchain Technology
The 
blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust in the past
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
now, blockchain technology will be very popular, especially in the financial sector. Ant finance, laikelib, Wanda, Ping'an and Minsheng have tried blockchain projects one after another, and European crowdfunding is in the forefront of using blockchain technology. The most successful case is digital currency

3. Private blockchain
private blockchain: it only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and only enjoys the write permission of the blockchain. This chain is not very different from other distributed storage schemes

today is a short day, isn't it? I will study hard from tomorrow. Today, isn't it just 24 hours? I'll start working hard tomorrow. Today is 1 / 365 of a year? My friend, why do you put what you want to do tomorrow and start from tomorrow? The sun and the moon are in a hurry. When tomorrow comes, tomorrow becomes today, and after every today there is an endless tomorrow. So, when will your determination and your ideal turn into action and reality
if farmers do not pull weeds, fertilize and kill insects in time today, how can they have a good harvest in the golden autumn? If the doctor does not rescue and treat the patients in time today, how can people be healthy in the future? If the cleaners don't clean the garbage in time today, how can the city be clean day after day? If the PLA soldiers are not fully armed and well prepared today, how can there be permanent peace for thousands of families
"tomorrow will be tomorrow, and there will be so many tomorrow; My life is waiting for tomorrow, and everything will be done in vain. "Just a few lines of poetry are the crystallization of the life experience of our ancestors after thousands of songs and hardships! The ancients had a sense of this, so they had the stories of "hanging the beam to stab the stock", "Ying Ying Ying snow" and "digging the wall to steal the light". Now that our conditions are superior, we should cherish today and seize every minute of it
to grasp today is to grasp the knowledge today; To seize today is to seize the possibility of invention and creation. Smart, diligent and ambitious people deeply understand that time is life, even more precious than life. They will never waste today's precious time on tomorrow. Edison, the great inventor, always cherished his time. He used his spare time to sell newspapers in the car to do experiments. When he was thirsty, he drank cold water; Hungry, chew a piece of bread; Sleepy, lying on the table to take a nap. Newton, Madame Curie, Einstein... This is true of all aspiring and successful people. They never inlge in wasting their time yesterday, destroying the light of life; Make efforts in time to open up the way of thinking. Friends, don't wallow in yesterday, don't wait and see tomorrow, everything starts from today! Today is the starting point of struggle!
