Blockchain answers

1. blockchain technology is a decentralized consensus mechanism to maintain a complete, distributed and tamperable ledger database. It can enable the participants in the blockchain to achieve a unified ledger system without establishing a trust relationship
in the future, blockchain will be applied in any field and bring great impact on human life. Blockchain technology is regarded as one of the main protocols of the next generation of value Internet. Blockchain technology will be useful in any field of proction and life that lacks trust. From digital currency to securities and financial contracts, health care, games, artificial intelligence, intelligent contracts, Internet of things, identity authentication, asset trading, e-commerce, social communication, file storage and other fields can be widely used
in the aspect of medical treatment
when the blockchain technology is used to save the personal medical records, there will be the historical data of personal medical treatment, which can be understood as the electronic medical records on the blockchain. In the future, there will be data for medical treatment or health planning, and the real master of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology also helps to protect the privacy of patients
payment system
compared with the existing traditional payment system, blockchain technology can avoid the complex system, directly between the two sides of the transaction, does not involve intermediary institutions, even if part of the network is paralyzed, it will not affect the operation of the whole system. This method has the characteristics of low price, fast speed, and no intermediate fees
banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. Some banks with keen sense of smell in the world have begun to actively plan to join the army of blockchain research and application in order to gain the initiative in the fierce competition in the future
identity authentication of blockchain
blockchain has the feature of being accessible to everyone. Everyone can query the block information in any place with network. The high transparency also makes blockchain full of charm. In the future, ID card and account book are basically not needed, because every identity information can be written into the blockchain. When you need to verify the information, you only need to look it up to find it
election
based on the voting transaction on the blockchain, it can be confirmed that no vote has been modified or deleted, and there will be no improper voting
Real Estate
blockchain technology can change the operation mode of the real estate market. It can combine many complex processes and cases that real estate companies usually deal with, speed up the transaction process, rece fraud, and provide more transparent and secure transactions for each participant. Provides a way to achieve paperless and fast trading needs
the probability of various kinds of errors in securities issuance and trading, such as general stocks, is too high, which requires manual correction, thus prolonging the time required for transaction settlement. Through the transaction of distributed ledger, the automation of the whole process can be realized, and the security and efficiency can be improved. The identity and transaction volume of the trading party are recorded on the blockchain in real time, with an open, transparent and traceable system. It is concive to the market maintenance of securities issuers and regulatory authorities, and can rece the occurrence of black box operation and insider trading
in the scenario of relatively closed, multi-party trust problems and carrying value transmission, blockchain has unique technical advantages and also shows unique charm, which has great application imagination space. At the current stage, blockchain is worth exploring in some scenarios.

2. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

in other words, blockchain solves the problem of trust and security
