A. How to trade in blockchain

Blockchain transactions are generally traded through digital currency trading platforms. There are many related platform introductions on non-small platforms, which can be used as needed. Choose
Explained from an academic perspective, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database.
For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all your best friends, classmates, Colleagues, as well as various groups and circles of friends, make it impossible for him to deny it anymore. This is called blockchain.
The core advantage of blockchain technology is decentralization. It can achieve decentralized credit in a distributed system where nodes do not need to trust each other by using data encryption, timestamps, distributed consensus and economic incentives. Point-to-point transactions, coordination and collaboration, thus providing solutions to the problems of high cost, low efficiency and insecure data storage common in centralized institutions.
The application fields of blockchain include digital currency, certificates, finance, anti-counterfeiting and traceability, privacy protection, supply chain, entertainment, etc. With the popularity of blockchain and Bitcoin, many related top domain names have been registered. , which has had a relatively large impact on the domain name industry.

C. Digital RMB salary payment! See how blockchain technology can "protect" your wallet

On September 10, Di Gang, deputy director of the Digital Currency Research Institute of the People's Bank of China, spoke at the parallel forum "Area" of the 2021 China (Beijing) Digital Finance Forum "Blockchain Empowers the High-Quality Development of the Digital Economy" stated that the Central Bank's Digital Currency Research Institute is actively exploring the application of digital RMB blockchain. Previously, Xiongan New Area applied the fund payment blockchain system to realize the salary payment of builders. This system not only saves salary transaction costs, but also makes transaction data open and transparent, ensuring the authenticity and security of transactions.

The principle of applying blockchain to digital renminbi

The capital payment blockchain system uses blockchain as the underlying system and applies digital renminbi to implementThe value transfer of current wages has the characteristics of distributed storage, anonymous encryption, point-to-point transactions, and instant settlement of the blockchain.

1. Distributed ledger

A distributed ledger is a database distributed across multiple nodes. Each node stores the same copy of the ledger and shares ledger information. After the digital renminbi is added to the blockchain, it can not only confirm and register the digital currency, improve the security of data and systems, but also record ledger transaction information on different servers, creating a distributed and publicly viewable database for banks. network to ensure that transaction data is accurate and transparent.

2. Peer-to-peer transactions

The decentralized nature of the blockchain means that it is not controlled by the server. Each node is equal and jointly maintains the entire network of nodes. data information. In addition, each node follows the rules of the cryptographic algorithm and does not require endorsement by a third party or trust agency. Under this feature, digital RMB can be directly traded point-to-point, realizing the simultaneous transfer of transaction information and value.

3. Smart Contract

Simply put, a smart contract is a digital agreement that uses algorithms to write contract terms and deploys them on the blockchain to automatically execute according to rules. When distributing digital RMB wages, the construction general contractor initiates payment settlement on the blockchain system and uploads the builder's wallet ID and salary amount to the chain. The system will ensure it in the form of smart contracts under open and transparent conditions. Transaction security; during the transaction, the transaction note will be broadcast throughout the network to ensure that the transaction information is difficult to tamper with; after the transaction, the smart contract will be executed and the digital renminbi will be automatically transferred from the construction party's wallet to the builder's wallet. In this process, the two parties directly transferred the value of digital renminbi, saving the cost of intermediate links and achieving point-to-point instant settlement.

Advantages of blockchain + digital renminbi

Compared with traditional electronic payments such as WeChat and Alipay, digital renminbi does not rely on banks. Users can obtain storage, payment, and Inquiry and other services. When transferring money, digital renminbi supports offline payment. Users only need to scan codes, remittances, touch and other interactive methods to realize the transfer of funds, avoiding delays in arrival due to network obstacles, and realizing "transaction and settlement". ". In addition, digital RMB wallets have lower requirements for users, and users do not need real-name authentication, which reduces the risk of information leakage from banks, third parties and other institutions. With the support of blockchain technology, the advantages of digital renminbi are gradually highlighted.

In addition to payroll, the application scenarios of blockchain have also expanded to cross-border payments, domestic letters of credit and other financial fields. In short, blockchain technology has built a trustworthy ecological environment for us, improved the transparency and authenticity of assets, and ensured the security of information data.

D. What is blockchain technology What is blockchain in popular explanation

Since blockchain 10Since the end of the month, it has been at the forefront.

What is blockchain technology

Although blockchain has been around for more than ten years, many people still don’t know much about this technology.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. From an application perspective, blockchain is a distributed ledger.

So, why is the blockchain called the blockchain?

Because the blockchain itself is a series of linked blocks, these blocks are filled with transaction records. The blocks are much like the records of a database. Every time data is written, it Create a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

What are the characteristics of blockchain technology?

Simply put, blockchain has the characteristics of decentralization, openness, non-tampering, and anonymity.

1. Decentralization:

In the blockchain system, there is no center.

In the blockchain model, it is distributed accounting and storage. Each node self-verifies, transmits, and manages information. Each node is the center, which is decentralization.

2. Openness:

The blockchain system has the characteristics of openness. The data is open and anyone can query the blockchain data and data through the public interface. Develop related applications.

3. Information cannot be tampered with:

In the blockchain system, once the data is written, the tampering cannot be undone unless 51% of all data nodes are controlled. Forge a record that does not exist. Therefore, blockchain technology has a certain degree of security.

4. Privacy and anonymity:

The cryptography technology in the blockchain can effectively achieve identity concealment.

The identity information of each node does not need to be disclosed or verified, and information transfer can be done anonymously. It can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.

Xiao Li lent 10,000 yuan to Xiao Wang. Xiao Li found two people in common and Xiao Bai to prove it. This accounting model is a centralized accounting model, and Xiaobai is the center.

However, a year later, when Xiao Li wanted to get the money back, Xiao Wang Shikou denied that he had lent him the money. It turned out that Xiao Wang introduced Xiao Bai's girlfriend to his company. a job.

This is the disadvantage of centralized accounting.

Xiao Li learned a lesson and gained wisdom. If someone asked him to borrow money in the future, he would say on WeChat in the village that I would lend so-and-so how much money to whom. In this way, the whole village knew how much money Xiao Li lent to whom.

In this way, when Xiao Li asks for debt again in the future, the other party will not deny the issue, because a consensus mechanism has been established in the minds of the people in the village: How much did you borrow from Xiao Li? .

This is the advantage of decentralized accounting.

Because after all, there are many people to testify about this transaction. If it seems to be a fraud, it will be unless more than half of the people in the village are bought. However, the price is very high.

In fact, these characteristics of the blockchain are all to solve the problem of "trust". The rich application scenarios of the blockchain are also based on the blockchain's ability to solve the problem of information asymmetry. At the same time, Blockchain also helps achieve collaborative trust and consistent action among multiple entities.

What are the applications of blockchain?

In addition to digital currency, there are many application scenarios of blockchain.

1. Medical field

Blockchain helps realize smart medical care, such as going to the hospital to see a doctor. Through the blockchain model, the patient’s medical status, cases, treatment status, etc. are all Clearly visible, saving a lot of medical resources.

2. Copyright field

Blockchain can prove the authenticity and uniqueness of the copyright of works, from the birth to the transfer of audio, video, pictures, text and other works. Can be tracked and recorded, and form tamper-proof information.

3. Logistics field

After applying blockchain in the logistics field, goods can be traced from production to consumption.

4. Food safety

Is blockchain used for food safety? Through blockchain traceability, one can easily trace the past and present life of their food.

5. Securities trading

For example, traditional securities trading requires the coordination of multiple institutions to complete, while the blockchain system can independently complete one-stop transactions. This service can make securities trading simpler and faster.

However, many people have big misunderstandings about blockchain. The biggest misunderstanding is: blockchain = Bitcoin

In fact, blockchain and Bitcoin is not the same thing. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the first application of blockchain.

E. What is peer-to-peer distributed technology in blockchain?

“A network-based computer processing technology, corresponding to centralized. Due to the extremely high performance of personal computers, big improvement andThe spread of its use makes it possible to distribute processing power to all computers on the network. Distributed computing is a concept opposite to centralized computing. Distributed computing data can be distributed over a large area. ”

F. What does blockchain technology mean?

Blockchain technology uses block chain data structures to verify and store data, and uses distributed node consensus algorithms to generate and A new distributed infrastructure and computing paradigm that updates data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. It is strung together by blockchain technology. A connected distributed ledger allows two parties to effectively record transactions and permanently verify this transaction.
Extended information
The basic principles of blockchain are not difficult to understand. Basic concepts include:
Transaction ): An operation that results in a change in the ledger status, such as adding a record;
Block: records transactions and status results that occurred within a period of time, which is a consensus on the current ledger status;
Chain (Chain): It is composed of blocks connected in series in the order of occurrence. It is a log record of the entire state change.
If the blockchain is used as a state machine, each transaction is an attempt to change the state, and each time The block generated by consensus is the participants’ confirmation of the state changes caused by all transaction contents in the block.
Explained in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as a The principle of accounting is to find the person with the fastest and best accounting within a period of time, let this person do the accounting, and then send the information on this page of the ledger to everyone else in the entire system. People.
This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed ledger.
The current applications of blockchain mainly include Two models:
1) Native blockchain applications: directly based on decentralized blockchain technology, realizing applications such as value transfer and transactions, such as digital currency;
2) "Blockchain+ "Mode: combine traditional scenarios with the underlying protocol of the blockchain to improve efficiency and reduce costs. It is expected that the application of blockchain in various industries will be dominated by the second mode.
Blockchain has five major The core attributes are: transaction attributes (value attributes), certificate attributes, trust attributes, intelligence attributes, and traceability attributes. The above core attributes are combined with the needs of the industry to solve the industry's pain points and become the application of blockchain in various industries. Business model.
As a basic technology, blockchain has great application value in many industries with distributed processing, peer-to-peer transactions, and rapid establishment of trust relationships. Its core is to solve the problem of credit. , realizing the point-to-point transmission of value. Therefore, it is considered to be the cornerstone of the future value Internet.
The core of the blockchain business model is to use the innovation introduced by the blockchainThe new attributes are combined with traditional industry applications to reconstruct business logic in order to create new application scenarios, or improve efficiency and reduce costs.

G. The Binance Chain testnet is officially open, and cryptocurrency trading has entered a new era

Binance, the world’s leading digital currency trading platform, announced the launch of Binance Chain and Binance DEX Testnet". Binance DEX is a decentralized trading platform based on Binance Chain. Users can create wallets and issue and trade tokens on the Binance DEX Testnet.

Binance Chain is a peer-to-peer distributed blockchain system developed by Binance and the Binance community. Binance DEX is a native decentralized trading platform built on Binance Chain. Its network is powered by Composed of centralized nodes, Binance DEX supports the issuance and listing of cryptocurrencies on it. Each node of the blockchain performs decentralized order matching, and all transactions are recorded on the chain, thus forming a complete and auditable transaction account.< br />
Binance CEO Changpeng Zhao said that "Binance DEX private keys are completely controlled by users. We provide users with a safer, freer and easier-to-use trading platform, and users have higher asset control." "You can manage your own assets more freely," but it also requires users to have a higher security awareness.

“The biggest highlight of Binance Chain is its high-speed transaction performance. As we all know, the matching speed of most existing decentralized trading platforms is much lower than that of centralized platforms, but on Binance Chain it can be almost instantaneous. To complete a transaction, Binance Chain’s block generation time only takes 1 second. Its speed is higher than other blockchains, and we have developed products based on the processing speed of centralized trading platforms from the beginning," said Binance CEO Changpeng Zhao. He also pointed out: “Ethereum takes about 20 seconds and Bitcoin takes an average of 10 minutes to obtain network confirmation, and rollback may occur. This will not happen on Binance Chain. With the support of Binance Chain core technology, Binance DEX is capable of handling the transaction volume that Binance currently handles. This solves the speed and performance challenges faced by many other decentralized exchange platforms."

Binance Coin (BNB) is currently based on ERC20 The tokens will soon be transferred to Binance Chain and switched to operate as the main network. Users can issue, send and receive new tokens on Binance Chain, and can also list new currency trading pairs. BNB will serve as the base currency of Binance Chain, and any operation on the chain will consume BNB.

Binance DEX will support both decentralized software and hardware wallets. Currently, Binance Chain has completed functional integration with Trust Walle and Ledger Nano S wallets.More wallets will be supported.

“We are working hard to create a decentralized way to obtain cryptocurrency,” said Viktor Radchenko, founder of Binance Trust Wallet. “We want users to have full control of their private keys and easily obtain decentralized application, maximize the mainstream application of cryptocurrency, and realize the potential of cryptocurrency to the greatest extent. Binance DEX has taken an important step towards Binance’s vision of currency freedom.”
