What are the products of blockchain
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
A: blockchain is an encrypted database chain, that is, the transaction data in multiple timestamps / events are encrypted and linked together, and the data can not be tampered with or shared
2. Performance and logic:
A. external operation forms: bank deposit and withdrawal, remittance, account in and out, shopping, currency issuance, capital transaction, etc
B. internal logic processing (software program): after human operation, the data will be encrypted first and then stored in the database. After the program, the data will be divided into regions, such as the data in the event and time stamp will be classified and put together into a region. Multiple events and data in timestamps are associated to form a blockchain. The encrypted data can be shared, but not tampered with
C. forms of sharing: querying personal information, auditing, etc. Query permission / sharing permission: different permissions can query different data. For example, the bank can query the information of all people, and the indivial can only query the indivial
3. Most of the examples are different, but the logic processing ideas are the same, but the implementation methods and operations are different
4. Blockchain: it has the characteristics of encrypted data, tamperable data and shared data
5. Blockchain Technology: the technology of encrypting, partitioning and sharing data with editing programs
there are suggestions for guidance
application fields: finance, it, commodity sales, online shopping, etc.
financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment
in the field of Internet of things and logistics, blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain
in the field of public service
blockchain is closely related to people's proction and life in the fields of public management, energy, transportation, etc., but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with
in the field of digital right
through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection
in the field of insurance
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
public welfare
the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
BSC cloud box is also one of them, which is worthy of special introction
from the point of view of time nodes, BSC cloud box is one of the earlier models. Gamer cloud came out earlier than BSC cloud box. However, in a major revision later, BSC cloud box mode was still used. From the perspective of risk control, BSC does the same as gamer cloud
but BSC cloud box is 100 times and 10000 times better than other procts - dividend mechanism
in short, the BSC system uses your idle computing power and traffic to make profits, and then distributes the profits to everyone according to the amount of contributed computing power and traffic
that's what everyone says, but how many people really give dividends
the dividend in the first quarter of 2019 has been completed. I didn't get the dividend because of my own nonsense and disagreeing with the government, but some friends around me got the dividend, the six figure level, and the highest one got the seven figure level. Of course, other people also made a lot of investment and contribution
this is the first blockchain proct that I have seen since I came into contact with blockchain, which really pays dividends. I am convinced that I will not mess with it in the future, and I will follow suit in a down-to-earth way.
many people think that digital currency is a gamble or fraud, and the Chinese government has not recognized the legal status of digital currency. However, is there a problem? It is often the trading platform that collapses, while the digital currency itself still exists. Bit, REBO, oranges, etc. still have trading volume. So now, choosing a good trading platform is the problem
as for which trading platform you say is reliable, ha ha, I really can't tell. No trading platform is endorsed by any government in today's world. It is privately operated, and most of them are registered in places without strict financial supervision. Every time, that's gambling. What's more, I don't rule out that if I make my own fake shop and don't accept international offers at all, I'm just entertaining myself. Not to mention the ordinary people, even the financial experts are not few
for digital currency, ordinary people should do as they can.
