Blockchain technology is a decentralized knowledge mechanism to maintain a complete, distributed and tamper-proof ledger database. It enables blockchain participants to achieve a unified general ledger system without establishing a trust relationship.
In the future, blockchain will be applied to any field, which will have a huge impact on human life. Blockchain technology is regarded as one of the main protocols of the next generation value Internet. Blockchain technology will be useful in any production and life field that lacks trust. From digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, identity authentication, asset trading, e-commerce, social interaction, file storage and other fields can be widely used.
Medical aspects
Using blockchain technology to save personal medical records will have historical data of personal medical care, which can be understood as electronic medical records on the blockchain. In the future, there will be data available for seeing a doctor or planning your own health, and the real master of these data is the patient himself, not the hospital or a third-party institution. 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 complex systems and directly carry out between the two parties without involving middlemen. Even if part of the network is down, it will not affect the operation of the whole system. This method has the characteristics of low price and high speed, and there is no intermediate handling fee.
banking
As a digital, secure and anti-interference account, blockchain has realized the core function of the banking industry: the safe storage and transfer center of value. Some banks with keen sense of smell in the world have begun to actively plan and join the blockchain research and application army in order to take the initiative in the fierce competition in the future.
Blockchain identity authentication
Blockchain has the characteristics that everyone can consult. Anyone can check the block information anywhere with internet. High transparency also makes blockchain full of charm. In the future, ID cards and household registration books are basically unnecessary, because every identity information can be written into the blockchain. When information needs to be verified, it can only be found by consulting.
elect
Based on the voting transaction on the blockchain, it can be confirmed that no votes have 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 merge many complicated processes and cases that real estate companies usually have to deal with, speed up the transaction process, reduce fraud, and provide more transparent and secure transactions for each participant. It provides a way to realize the demand of paperless and fast transaction.
Securities issuance and trading
Generally, the probability of all kinds of errors in securities transactions such as stocks is too high, which requires manual error correction, thus prolonging the time required for transaction settlement. Trading through distributed account books can realize the automation of the whole process and improve safety and efficiency. Information such as the identity and transaction volume of the counterparty is recorded in the blockchain in real time, plus an open, transparent and traceable system. It is beneficial for securities issuers and regulatory authorities to maintain the market and reduce the occurrence of black-box operations and insider trading.
Blockchain has unique technical advantages, unique charm and huge application imagination space in relatively closed, multi-party trust issues, carrying value transfer and other scenarios. At this stage, blockchain is worth exploring in some cases.
