A summary of blockchain
blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services. In October 24, 2019, ring the eighteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". "Blockchain" has entered the public field of vision and become the focus of social attention
on December 2, 2019, the word was selected into the top ten catchwords of "biting words" in 2019

Application of blockchain Finance:
since 2016, the major financial giants have also carried out blockchain innovation projects to explore the possibility of applying blockchain Technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency
standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization, which is written into the blockchain through careful digital algorithm to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency
in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016
the meeting will discuss the realization of digital circulation of assets by blockchain, the financial transaction mode of blockchain, and the application of blockchain services and social public instry. This conference will mark the beginning of the application of blockchain finance and the change and development of the new financial ecology
whether it's the introction in the network, the answers given by everyone, or the simple and easy to understand introction, you may not really understand blockchain. It's recommended to read more relevant information to understand its landing application. Cryptofinance focuses on blockchain information
blockchain is used to record public data together, or more narrowly, to keep accounts
for example, you recorded that Zhang San owes you 10000 yuan in your computer, and Zhang San said that you still owe me 1 million yuan in my computer. So what
it used to be solved like this: find a notary, and your accounts will be recorded in the notary. In case of any dispute, the notary's account book shall prevail. For example, this is what banks do. Both of your money is deposited with him. There are records of transfers and loans
blockchain solves this problem: when you keep an account in your own computer, Zhang San also records the same data in his own computer. After recording, you two check with each other and agree. This account is officially recorded. There is no need for the participation of a third party or the so-called "authority" or "certification body"
the way that everyone keeps accounts together is also known as "distributed" or "decentralized", because everyone keeps accounts, and the accuracy of the account book is determined by the program algorithm, not an authoritative organization
extended data:
blockchain is characterized by abnormal security, non tampering, accessibility and no third party
its application scenarios include, but are not limited to, no need to prove that "my mother is my mother" in the future. The tamper proof feature of blockchain technology has fundamentally changed this situation. Our birth certificate, real estate certificate and marriage certificate can be notarized on the blockchain, becoming something trusted by the whole world. Of course, it can also easily prove that "my mother is my mother"
for another example, we often use Ctrip, meituan and other apps to find and place orders for hotels and other services, and each platform gets a commission from them. The application of blockchain is to remove middlemen and create a secure and decentralized way for service providers and customers, so as to achieve the purpose of direct connection and transaction
we usually think that the one who maintains the system is the one who manages the database, and other users have no right to participate. Just like the users of a certain treasure can not participate in the specific bookkeeping behavior
but blockchain subverts the tradition and lets every user in the system participate in it
blockchain is like a large total account book. Every user in the system can participate in competitive bookkeeping. In a certain period of time, the system will find the fastest and best users among competitors. The user writes the data changes in this period to a block, just like writing to an account page, and copies this account page to all other users in the system for backup, completing the whole action. In the next period of time, every node in the system has a of the complete ledger
since each block data is linked together through cryptography technology, we call it "blockchain" or "distributed ledger technology"
blockchain, let the whole people participate in bookkeeping. Because there is no specific bookkeeper in the system, any part of the nodes in the system will not affect the operation of the system if they are lost or destroyed. It is safer for all people to keep accounts. The system stipulates that the same number of accounts with the largest number are true accounts, and a small number of accounts that are inconsistent with other users are false accounts. This makes it difficult for a blockchain with enough nodes to be attacked and tampered with. These nodes are distributed in any corner of the Internet. Unless you are God and can control most computers in the world, you cannot tamper with them. Therefore, blockchain is considered to be the most secure way of data management in history. National bookkeeping is more efficient. Because there is no centralized intermediary organization, it can run automatically through pre-set proceres, which can greatly rece costs and improve efficiency, and ensure that the process and content of account records are open and transparent
bitcoin is only an experimental application of blockchain technology in the field of payment. Blockchain can also be used in a broader field, including medical treatment, supply chain, Internet of things, security authentication, social networking and artificial intelligence The economist called blockchain "the trust machine" and believed that it would have a huge and far-reaching impact on global finance and even social structure
to sum up in one sentence, blockchain technology is a way that enables all participants in the system to work together to record and maintain a reliable data log under the environment of multi-party without mutual trust through cryptography technology
bitcoin, blockchain content publishing platform decent and lightcoin all use blockchain technology, and anyone can participate in it in theory.
