Why blockchain can change the world

1. 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.

2. 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.

3. Blockchain is just a program mode. The data formed by this program mode is traceable. Compared with other program modes, blockchain programs are more fair, safe and not easy to tamper. It only plays a role in the protection of property rights
it seems that some experts and scholars say that the value generated by blockchain will be ten times that of the Internet. They really disagree with this view. Shanghai is the city with the highest GDP in China and has great development potential. If someone says that the value created by Shanghai will be ten times that of the whole China, what do you think
blockchain is based on network and computer. How can it generate ten times the value of Internet?

4. The traditional centralized institutions occupy most of the social resources, they are the collectors and monopolists of market information and make profits. Blockchain will let all this become the past, and the future will be an era of information sharing
the book "blockchain: blueprint and guide to the new economy" (New Star Press, January 2016), written by Melanie Swann, founder of blockchain Science Research Institute, points out that blockchain plays the same role in trust as the Internet in information. Like the early Internet, blockchain has the potential to innovate everything, and blockchain is the source of power for the fourth generation of instrial revolution. Melanie also constructively proposed the possibility of using blockchain to automatically track all digital behaviors and create a decentralized digital information base for identity verification, so as to provide services traditionally provided at the national level with lower cost and more efficiency
at present, international giants such as Microsoft, Tencent, Wanda, Goldman Sachs, JPMorgan Chase and Dell are all testing blockchain projects, and small and micro enterprises such as European crowdfunding have become the first to eat crabs.

6. Theoretically, blockchain is a relatively simple technology, but it can be proved to be very effective. So jinwowo thinks that it may not change the world, but it can bring benefits and advantages to many instries

A: "blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. " 1、 In the narrow sense of blockchain, blockchain is a kind of method that blocks data in chronological order.

8. Blockchain belongs to the underlying technology of the Internet
today's blockchain is like the Internet of the 1990s,

9. Some people say that blockchain can change the world like the Internet. What are the similarities between blockchain and the Internet
Internet is a decentralized information transmission system, and blockchain is a decentralized value transmission system. Both are known as great technologies that change the times
the main purpose of the Internet is to realize the rapid transmission and reception of information. Word documents are actually copies of information on the Internet. You have one and others have one
the blockchain is used for value transmission. The transmission of bitcoin on the blockchain is essentially the transmission of ownership. Your bitcoin becomes someone else's bitcoin
the data on the blockchain is highly tamper resistant and can only be used after being verified by most nodes in the whole network. Once the records are recorded, they cannot be modified. Every value transmission on the blockchain is clearly recorded and traceable. Blockchain can build trust among centers. Some people say that blockchain can change the world like the Internet.
