blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more
In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independentlyextended data:
type of blockchain
1, public blockchain
any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world
2, Alliance (instry) blockchain
instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain
3, private blockchain
only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes
5.
(1) Technical level. Since 2007, distributed computing has affected technical developers, so it is normal for bitcoin to appear in the field of virtual currency
(2) hardware level. The popularity of PC servers and the exponential growth of computing power (3) commercial level. The three characteristics of blockchain, namely, decentralization, distrust and extremely difficult forgery, just meet the needs of recing the trust cost and speeding up the transaction speed in financial fields such as stock trading and bank settlement (4) political level. Blockchain can rece the transaction cost to a certain extent, but the anonymity and untraceability of blockchain cause huge political risk[blockchain as the underlying technology of bitcoin was proposed at the end of 2008]
6. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

7. Since the origin of money, the development of trade between people and countries has become more smooth and convenient. The exchange of trade proces a large amount of transaction information, which is initially recorded by some special systems, such as the government system and the banking system, so it is often confidential and not open to the public. Therefore, when we trade with unfamiliar counterparties, we need reliable third parties or intermediaries who have the above information records to help us audit the authenticity of the transaction, such as the government, banks, accountants and notaries. These are called "reliable third parties"
the emergence of bitcoin makes the status of "trusted third party" in danger. Bitcoin maintains a public account book through computer networking, which is completely open and not controlled by any organization. To be more precise, it is a large digital ledger that is publicly accessible and maintained by the whole distributed network, which we call "blockchain"
in the blockchain, all transactions are recorded, including the date, time, trading partner and number of transactions. Each node in the network has a complete of the blockchain ledger, which is equivalent to that each node has a of the ledger. Blockchain uses advanced and complex mathematical principles to allow all users in the system to participate in bookkeeping competitively. In a certain period of time, the fastest and best user records will be selected and recorded in the big ledger
nationwide bookkeeping makes the system have no specific independent third-party bookkeeper, the records on any node of the system are lost, and the other nodes have a full set of books, so that the information transmission and transaction conclusion will not be affected. If someone tries to make fraulent transactions, its node information will not be able to reach a consensus with the network, because its account book content is inconsistent with most people's account books, so it will not be recognized by the public, unless he can tamper with the account book records of more than 51% nodes. Obviously, this is difficult to achieve, because no one can control the accounting computers distributed on nodes all over the world at the same time. Therefore, blockchain will not lead to false transactions
through the blockchain, every transaction is open, and thousands of nodes anonymously identify the date x, time y, quantity n, etc. of the transaction, which is just like justifying all transactions as a notary. In this way, we share the same data source, which is open, transparent and reliable. This is the reason why we trust blockchain and the essential attribute of blockchain technology
in short, blockchain can subvert the existing world. Ethereum and decent are the most typical examples. However, at present, they only stay in theory.

8. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology or a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book, because the account books of all nodes are consistent, and different nodes can trust each other, so there is no doubt about the data, So we all say that blockchain realizes trust technically
based on trust, bumeng has built a digital asset platform, which allows enterprises to issue their own assets. In fact, it is an exploration based on the characteristics of blockchain technology to let these assets circulate freely.

9. Blockchain is a kind of virtual currency. It needs to invest money and should be cautious
10. In just a few years, blockchain has developed from 1.0 era to 3.0 era. The update of each "era" has brought changes to the world. The development of blockchain can be divided into three stages from 1.0 era to 3.0 era: point-to-point transaction, transaction and transaction Smart contract and blockchain application Ecology (token economy)
blockchain 1.0 era: digital currency rate of return is the king
blockchain 2.0 era: smart contract provides infrastructure support for upper application development
blockchain 3.0: the subversion of business lies in the transformation of proction relations
all obstacles to the development of human society, Fundamentally speaking, they are all caused by "mutual distrust", especially various economic and financial crises. If human beings can solve the problem of mutual trust, then human beings will complete a very big leap forward
the development of blockchain has graally laid the foundation for this direction. Human beings are entering the era of "smart contract", which is the process of upgrading human trust mechanism. Once the smart contract is reached, human society is facing a new big upgrade. As a value creator, the value created by each indivial can be accurately recorded and the corresponding return can be obtained, There will be less and less mutual interference, and people are really moving towards independence and equality. Human civilization has evolved from "identity society" to "contract society", and blockchain is expected to lead human beings to transition from "contract society" to "smart contract society"
although blockchain has gone out of the conceptual stage, the current situation of blockchain technology development is that the underlying technology is not mature enough and the application scenarios are relatively limited. On the one hand, consensus algorithm and other core technologies of blockchain still have room for optimization and improvement; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. Moreover, the current mainstream blockchain technology platforms are originated from foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the global blockchain technology development. It still needs a certain period of time. It can be said that the whole domestic trend is waiting for the emergence of a super level blockchain project
