Blockchain will redefine the world

1. Generally speaking, blockchain is an "encrypted distributed synchronous updating accounting technology"
characteristics of blockchain:
the core potential of blockchain lies in the transparency, openness, traceability and non tampering of information
origin of blockchain:
blockchain technology originated from a special currency, and its essence is to create a decentralized monetary system
it's hard to say whether we can change the world in the future, but the future is very clear.

2. 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.

3. 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.

4. A blockchain based world builds trust among multiple parties to a transaction, which does not require them to have private contacts. Our current system uses validation and needs to balance costs. The blockchain world not only makes transactions faster, cheaper and truly global, but also allows each of us to control and track the distribution of our own data
companies like Goldman Sachs, IBM and Cisco, as well as organizations like the world economic forum, the IMF and the Bank of England are experimenting with this technology, which shows that this is not a flash in the pan concept, but a reality
Ethereum, an intelligent contract platform, and decent, a decentralized content publishing platform, are the pioneers of blockchain.

5. 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?

6. Blockchain is equivalent to the Internet in the 1990s. Looking at the impact of the Internet on the world from now on,
we can probably see what the future blockchain will be like.

bus line: Metro Line 3 → fan29, the whole journey is about 15.0km

1. Take Metro Line 3 from Dashi, pass 3 stops, and reach Panyu Square Station

2. Walk about 280m, and reach Panyu Square Station

3. Take fan29, pass 3 stops, and reach Hexian hospital (Qinghe East Road) station (you can also take fan160, fan99, fan68, and Fan1)

8. Blockchain is the underlying technology of bitcoin, which refers to a series of data blocks generated by using cryptographic methods. Each data block contains the information of all bitcoin network transactions in the past ten minutes, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
