1. blockchain encrypts the transaction information in a transaction block by hash algorithm, and compresses the information into a hash string composed of a string of numbers and letters. Jinwowo group analyzes the functions of its hash algorithm as follows: the hash value of the blockchain can uniquely and accurately identify a block, and any node in the blockchain can obtain the hash value of the block through simple hash calculation, and the calculated hash value does not change, which means that the information in the blockchain has not been tampered with.

3. 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
4. According to reports, blockchain has the advantages of decentralization, distrust and tamper proof
compared with the Internet, the blockchain network conceived by Cosmos not only realizes information interaction, but also realizes the transmission of asset value. Through the IBC cross chain protocol, the token can be transferred across the chain between the blockchains based on Cosmos' tendermint core. For the public chains based on POW consensus mechanism like Ethereum, pegged zone can be used to bridge

5. Blockchain features: 1. Security: not attacked by any person or entity; 2. No information can be tampered with; 3. Traceable, all nodes in the network can access; 4. Decentralization, no third party. About blockchain messages, you can learn about it in cryptography.

7. Tiktok and the audience are different, so a bit of praise is not necessarily tiktok. The other two platforms are different in algorithm and way. The core of the jitter is the tilting of the core author, and the main thing is to go centralization, so that everyone has the opportunity to become the peak of traffic. If the work is not tiktok, it is mainly considered whether the shooting solution is made for fans and the platform audience and platform traffic algorithm. Don't easily suspect that only when there is a problem with the platform can your works have no traffic. The possibility of problems with such a large platform is extremely small, and once there is a problem, it must not be you who are anxious first, and the network has already exploded.

9. For example, Hangzhou shimai Environmental Technology Co., Ltd. has made great progress in the instrialization of blockchain. The core technology of the company is the carbonization car with 26 patented technologies, which can solve the problem of harmless treatment of sick pigs and dead pigs caused by African swine fever. Through the movable characteristics of the carbonization car, the public food safety problem can be eliminated from the source of farmers in one stop. First of all, this mature technology has achieved good results, and has signed cooperation agreements with many local governments and relevant departments. Secondly, Hangzhou shimai has taken the lead in establishing a data center to transform all the carbonization vehicles of the company. The actual operation process of each vehicle has realized the distribution record, each dead pig has been photographed on the chain, the corresponding hash value has been generated, the whole process is traceable and traceable, and the advantages of blockchain technology have been used to ensure the whole process of harmless treatment.
10. The average time of reimbursement in the traditional medical insurance window here is about 12 working days. Now, there is no need to take paper bills to the medical insurance window of the insured place to apply. You can directly apply for online reimbursement through the "zheliban" app. With ant blockchain technology, the average reimbursement time is reced from 12 working days to a few minutes, which greatly facilitates daily life.
