From the district network sharing, the blockchain is a special distributed database. The main role of the blockchain is to store information. Any information that needs to be saved can be written to the blockchain or read from it. Anyone can set up a server and add the blockchain network to become a node. In the world of blockchain, there is no central node. Each node is equal and keeps the entire database. You can read or write data from any node. Because all nodes will be synchronized to ensure that the blockchain is consistent.

Pay content for time limit to check for freenAnswer dear ~, thank you for your question, please wait a while, here is sorting out the answer, thank you for your understanding*⸜ (• ᴗ •) ⸝*nDear, the essence of the blockchain is a distributed public ledger. Anyone can check this ledger, but there is no single user to control it. Participants in the blockchain system maintain the update of the ledger together: it can only be modified in accordance with strict rules and consensus.nExample: If A borrows B 100 yuan, at this time, A shouts in the crowd, "I am a, I borrowed it to B 100 yuan!", B also shouted in the crowd, "I am B, A borrows a borrowing Give me 100 yuan! "At this time, passers -by A Yingding heard the news, so everyone silently wrote down" A to b100 yuan "in his heart. This system does not require banks, no loan agreements and receipts. Strictly speaking, there is no need for a long -term trust relationship between people (for example, B suddenly changed to say, "I don't owe A money!" At this time, the people will I will stand up and say, "No, my small book records that you borrowed A100 dollars one day!")n1 morenBleak

In general, blockchain technology refers to a way for the whole people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then whoever remembers this book becomes important. At present, who is the system, who will book the book, WeChat's ledger is Tencent's record, and Taobao's ledger is Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in the bookkeeping. If there are any data changes in a certain period of time, everyone in the system can come to account for bookkeeping. The system will judge the fastest and best person in this period of time. During a period of time, the contents of the ledger were sent to all others in the system to back up. Everyone in this system has a complete ledger. In this way, we call it blockchain technology. There are many products and applications developed based on blockchain technology. Like LifeChain is a medical and supporting enterprise based on blockchain technology. You can learn about it.
