1. What is bnb?

1. bnb is the abbreviation of Binance Coin. Binance Coin is a digital currency that is popular among a large number of users around the world. It is the world's top digital currency trading platform. Coin an is a virtual digital currency issued based on blockchain technology. The total number of issuances is 200 million, and the platform promises never to issue additional coins. The Binance platform requires a 0.5% handling fee during the transaction process. If you use the Binance platform to pay, you can get certain discounts.
2. BNB coin is a blockchain token. In September 2017, the domestic Bitcoin market ushered in strict supervision. At the end of October, Yuanan moved to Japan. On January 23, 2018, Binance announced that it would move out of China as a whole, and its users are basically from overseas. In March 2018, Yuanan encountered policy risks in Japan and moved to Malta. On October 9, 2018, a token user asked on Twitter if he had received payments from Alipay and WeChat. Changpeng Zhao, CZ (CEO) confirmed on Twitter. On October 11, Binance founder Changpeng Zhao stated that Weibo, Alipay and WeChat did not have any official cooperation in OTC. On the evening of November 13, Qian’an’s official Weibo account was blocked. On November 21, 2019, Qian'an's Shanghai office was closed after being raided by the police.

1. Digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: ① Due to some open algorithms, digital currency has no issuer, so no person or institution can control its issuance; ② Due to the determined algorithm solution, the total amount of digital currency is fundamentally fixed. It eliminates the possibility of inflation caused by the abuse of virtual currency; ③ Because the transaction process requires the approval of each node in the network, the transaction process of digital currency is safe enough.
2. The emergence of Bitcoin poses a great challenge to the existing monetary system. Although it belongs to a broad sense of virtual currency, it is fundamentally different from the virtual currency issued by online companies, so it is called digital currency. This article compares digital currency with electronic currency and virtual currency in terms of issuer, scope of application, issuance quantity, storage form, circulation method, credit guarantee, transaction cost, transaction security, etc.

2. What currency is busd?

BUSD currency is a stable currency issued based on blockchain technology and anchored 1:1 with the U.S. dollar. It is hosted by Binance Exchange Issuance, the full English name is Binance USD, and the total supply is 8,011,285 BUSD.
1. As a stable currency, every BUSD coin circulating in the market has a corresponding 1 USD asset stored in the bank. The iron law is that "the total amount of endorsed assets >= the total circulation of BUSD coins" , use an independent third-party accounting firm to audit assets and regularly disclose the audit results.
2. BUSD coin is also the first stable currency with its own independent client APP, which supports QR code scanning payment, collection, transfer and other functions to satisfy customers' collection and payment, consumption at merchants, and online mall shopping. , offline major industrial consumption, cross-border payment, various blockchain transaction media and other application needs, it is a new payment method driven by blockchain.
3. At present, BUSD currency has reached strategic cooperation relationships with overseas merchants, and is actively building and improving the existing ecosystem of stable coins. In the future, it will provide customers with more application scenarios and promote blockchain payment towards consensus. development direction.
Extended information
Development history of BUSD:
1. BUSD has achieved good performance in trading platform use cases, providing good liquidity and friendly transaction rates, loan interest rates and recharge rates, and contract cross-overs Security deposit etc. But we hope to further expand the application scope of BUSD. This time, we have explored many use cases beyond the trading platform, hoping to promote the popularization of BUSD. One example worth mentioning is BUSD’s entry into the field of decentralized finance (DeFi).
2. Last month, BUSD added $2 million in liquidity to the decentralized exchange platform (DEX) protocol Uniswap through the BUSD/USDT and BUSD/USDC trading pairs. At the same time, the trading platform liquidity pool Curve.finance listed BUSD on its stablecoin trading platform. Curve.finance and Yearn.finance have also established their own BUSD stablecoin pools.
3. Stablecoins play an important role in the DeFi field because they are usually used for margin assets or loan assets. BUSD creates the following advantages for DeFi protocols:
1) BUSD is a stablecoin that is regulatory-compliant and subject to regular audits, so it has higher stability.
2) BUSD has a strong user base, with more than 150,000 holders on the Binance platform.
3) BUSD has an extensive legal currency conversion channel support network. BUSD can be easily purchased and traded through fiat currencies and other currencies on the Binance platform.

3. Blockchain and Bitcoin (1)

Blockchain is a technology that has been proposed by academic circles for a long time but has only become popular with Bitcoin in recent years. a concept. Bitcoin is an implementation based on blockchain technology. Bitcoin is a cryptocurrency, or a digital currency. Let’s start with Bitcoin and talk about how Bitcoin uses blockchain technology.

Suppose that during the 2006 World Cup finals, two football fans who did not know each other met. Italy was playing France. The French fans said that France will definitely beat Italy with Zidane. The Italian fans were unconvinced and said that we Italy is invincible. If you don't believe it, let's bet 100 euros. In the real world, what should we do?

MeAs mentioned before, we who work on computers spend more than 90% of our time dealing with abnormal situations. If humans were very trustworthy, the world might not be what it is now. The 600 miles that Qin promised King Huai of Chu were no longer 6 miles. Maybe it would be Chu who unified China. If you hand over the money to a third party, what if the third party also runs away? He stole the money. Therefore, in the real strange world, relying solely on a kind heart is unreliable. There must be means to firmly guarantee this commitment, legal contract, etc. Nowadays, a very common approach is for the third party to find an authoritative institution, such as the government, a bank, etc., or to find a reputable person or organization. In the final analysis, it is still to find an institution or person with credibility. But under normal circumstances, this third party will definitely "pluck out hair" and charge a certain percentage of handling fees.

So is there any way to solve this problem? This is one of the original intentions of Bitcoin's original design, to solve the trust problem between two strangers.

Encryption algorithm + multi-person accounting

Let’s talk about the encryption algorithm first. Here we need the asymmetric encryption I mentioned before, that is, the public key and private key. Everyone can have one or more pairs of public and private keys, but a public key can only have a corresponding private key, and vice versa. The principle is that two very large prime numbers (p and q) are multiplied to get a number (n). If you want to crack the private key based on the public key, you must theoretically crack it violently and figure out which two large prime numbers the number is multiplied by. Got it. Currently, there is no published private key in the world that can crack more than 1024 bits, so it is very safe to use a private key of 1024 or 2048 or even longer.

Then with the public key and private key, I as an individual can encrypt with the private key, and then publish the public key. Anyone can use my public key to decrypt to determine that this is what I published. . In the same way, when someone transfers money to me, I can also use his or her public key to decrypt it and determine that this is someone's identity. This is also called a digital signature. The principles are the same, they are all encryption algorithms, obtained by using mathematical Euler's formula, prime number multiplication and other principles. This is a very great algorithm called RSA, proposed by three mathematicians. As long as we ordinary people understand the concept and use of public keys and private keys.

In the previous traditional model, banks or government agencies had their own separate ledgers. For example, if Zhang San transferred 100 yuan to Li Si, how would it be recorded in the ledger? 100 is deducted from Zhang San’s account and 100 is added to Li Si’s account, right?

The same is true for multi-person ledgers, except that the previous centralized institution has become a distributed, decentralized multiple institutions and even individuals. For example, Li Bai transferred 100 taels of silver to Du Fu. In the past, the Ministry of Finance kept accounts. In the blockchain, Tang Taizong, Yang Yuhuan, Zhang Xiaojing, He Zhizhang and many other people kept accounts together. It was recorded that Li Taibai transferred 100 taels of silver to Du Zimei. , as evidence, with Li Bai's seal attached at the back. thisIn this way, with multiple ledgers, it would be extremely difficult to tamper with it. Li Bai could safely transfer it to Du Fu without worrying that he would tamper with the amount or deny it.

This can solve the problem of fans betting mentioned at the beginning, but there is another question, why should others help us keep accounts?

The answer is to be paid, which is in line with human nature. Otherwise, who would be willing to help keep an account that has nothing to do with them?

But there is only one person who can ultimately keep accounts, otherwise everything will be in chaos.

On the premise that it is beneficial, how to ensure who will keep the accounts? There is a mathematical knowledge involved here. Everyone who wants to keep accounts, in fact, the so-called miners, must solve a mathematical problem when keeping money. There is no trick to this mathematical problem. The only way is to put the numbers into the formula. In hard calculation, the algorithm is a Hash algorithm, which is similar to calculating a series of numbers. Miners can only guess, but there is no other way. Moreover, the current probability of guessing in Bitcoin is one in a trillion. It would take an ordinary computer to guess this number continuously for about a year.

But there are thousands of computers in the world, and if they are calculated together, the speed will be much faster, because from a probability point of view, one computer will definitely calculate it, and this is indeed the case. Let’s look at a real-life example of Bitcoin.

In addition, you can also see who the Miner is and how many transactions (Number of Transactions) are included in this block.

What if this miner is an individual with ulterior motives, and after calculating the calculation, he tampered with the transfer record and amount privately?

A. Tampering with transaction records/amount

We introduced the public and private key encryption technology earlier. The miners themselves theoretically do not have the private keys of the sender or payee. Therefore, the transaction record that he tampered with will make errors when decrypted with the correct public key, and will eventually be deemed illegal (the author is not sure at what point in time the identification was made, but he is sure that this record can be falsified) ).

B. Delete transaction records

Assume a scenario where Zhang San wants to buy a two-bedroom, one-living house in Beijing’s 4th Ring Road, but Zhang San doesn’t want to pay for it. Occupying the house for free, I thought of a sneaky way to tamper with the transaction records. Theoretically, after Zhang San paid, this record was generated but not confirmed. The record needs to wait until a miner solves the puzzle. Assuming that the miner is one of his own, he asked the miner to erase the record. There is no problem. . But there are several ways to do it:

PubliclyIt is known that Bitcoin mining takes a long time because of the troublesome math problems to be solved. The current cycle is about 10 minutes. This is based on the premise that hundreds of thousands of mining machines around the world are working at full capacity at the same time. That is to say, tens of thousands of transactions will be uniformly confirmed and put into an immutable block every ten minutes, and these hundreds of thousands of mining machines will update their local records at the same time.

2.1 If the transaction is just generated and the landlord sees it, and then transfers the property rights to Zhang San the next second, then if Zhang San wants to tamper with the payment record, he must meet several conditions:

The difficulty of success depends on how many confirmed blocks follow the tampered record. If there is only one, it is too simple, because the blockchain algorithm defaults to miners using the first received longer block when publishing a new block. So after this modification, it will be done once and for all, because all the ledgers will be synchronized, but there is also a problem, that is, this synchronization will be recorded. If the landlord cannot check the account, Zhang San will eventually be arrested. If there are many, for example, after Zhang San transfers the money, the landlord only transfers the property rights 1 hour after confirming the transfer, then Zhang San must tamper with the previous block information of about 6 blocks, which is very troublesome, because every block All will point to the previous block, and each block will have a digest (Hash), which is a summary of all transaction records in the current block. So if you try to modify a block that was written a long time ago, the digests of subsequent blocks will be changed. This is the hash tree (MerkleTree). Other nodes can report information that the blockchain has been tampered with. This involves the most important point. The 51% computing power that is often mentioned means that if Zhang San owns more than 50% of the ledgers and acknowledges this modification, then other nodes will also acknowledge this modification according to the algorithm design. . However, let’s not talk about the fact that almost no one in the world can do the above two things at the same time. Even if you can do it, if someone has questions about this, you can still force the system to be repaired. Similar problems have occurred in Ethereum before, and the outcome is Ethereum Entire blocks were tampered with and stolen property was recovered. Ethereum fork event.

The above is only a superficial introduction to the characteristics of Bitcoin implemented by applying blockchain technology. It can achieve openness, fairness, neutrality and equality. Any two strangers in the world can rely on Bitcoin or other blockchain technologies to trust each other.

4. After reading this article, you will have a thorough understanding of the blockchain

In this article, all the content I introduced is in today’s world. The fact that the blockchain field has already happened is not some imagination or opinions about the blockchain. I think that as long as you read this article carefully, you will easily have a basic and accurate understanding of blockchain.

The main content of understanding blockchain in just ten minutes is divided into four sections, 21 sectionsTopic J4 sections are:

The first national blockchain strategy.

Second, Bitcoin and its literal representation involve four topics.

Third, blockchain and its technical logic involve 13 topics.

Fourth, blockchain empowers the economy and society, involving three topics.

Let’s first look at the first part of the blockchain national strategy, the first part of the blockchain country. Everyone knows that we humans have experienced six information revolutions. Seven or eight years ago, the first information revolution created primitive language, social tacit understanding, and the second information revolution saw the emergence of writing. The third information revolution in feudal society invented papermaking and printing, and the fourth information revolution in the late 19th century invented radio.

In the fifth information revolution of the 20th century, television appeared again, and now in the sixth information revolution, computers and the Internet have appeared. The emergence of computers and the Internet has given rise to the rapid development of various new technologies. Especially in 2020, the digital economy has experienced epoch-making development.

Why do you say that? The characteristics of high bandwidth, low latency and large connections in the 5G era have enabled the implementation of the four major technologies of ABCD.

What are the four major ABCD technologies

The a here refers to Artificial Intelligence, which is artificial intelligence technology.

B refers to Blockchain, blockchain technology.

C refers to cloud computing cloud computing technology

D refers to big data technology.

The word blockchain is now completely popular all over the country. On October 25, 2019, the Political Bureau of the Central Committee of the Communist Party of China announced the development of blockchain technology. The current situation has been collectively studied, so the requirement of this meeting is to use blockchain technology as the core technology.

As an important breakthrough for independent innovation, it is necessary to accelerate the innovative development of blockchain technology and industry. On April 20, 2020, the National Development and Reform Commission officially included blockchain into new infrastructure. Blockchain, why do you think it is so awesome? Let us say that blockchain is not an extension of the Internet, it is a subversion of the Internet. In the future, many, many technologies will grow on this blockchain and realize blockchainization.

So, how can we accurately learn and understand blockchain?

We found that in the four major technologies of ABCDAmong them, only blocks naturally have their own financial attributes. Therefore, we must learn and understand blockchain from the IT perspective and the financial perspective, and even learn and understand blockchain from the level of national governance. If you only study and understand blockchain from an IT perspective, it is impossible to understand the huge influence and influence of this technology. Then, your understanding of this will be biased. Even more, you may disapprove of blockchain technology. In addition, in the process of learning about blockchain, you should also pay attention to the fact that it has many new terms, so you need to concentrate on understanding it step by step.

Let’s first understand blockchain from a financial perspective.

Bitcoin and its birth performance

To understand the blockchain, it involves Bitcoin, and what about the birth of Bitcoin? , and it is inseparable from the evolution of currency. We know that currency is a special commodity that is separated from commodities and serves as a fixed general equivalent. In fact, we humans have used a lot of currencies, including physical currency, weighing currency, paper money, accounting currency, etc. As for accounting currency, it includes electronic currency and digital currency. Electronic currency itself is not a currency. It is just used to represent the same amount of currency. It is a token.

Then the total amount of his tokens will not increase due to the increase of electronic currency. Alipay, WeChat, payment, and online banking are typical electronic currencies. As for digital currency, it is itself a legal currency. The total amount of this fiat currency will increase with the increase of digital currency. We know that when it comes to physical currency, we humans have actually chosen many things as general equivalents.

Weighing currencies are some heavy metals. Later, people chose gold among the heavy metals. Why choose gold? Because gold has the characteristics of rarity, divisibility, and the most stable chemical properties. What needs to be noted here is gold. It is not issued by any country. It is provided by nature. of. Your country's total amount is as much as nature provides. Therefore, the country does not need to provide credit guarantees for the value of gold.

However, as for gold, it has some flaws in its use, and it is difficult to carry when you go out again, so there are descendants. Paper money appeared in the Northern Song Dynasty. At that time, paper money was not currency in the current sense. The currency at that time was still gold, but we used paper money to represent gold. We called it the gold standard. The gold standard is the gold standard, which is a monetary system with gold as the standard currency. The core essence of the gold standard isHow much currency a country issues should be decided based on how much gold your country has. You can't just issue as much currency as you want.

At that time, the Great Depression of the United States reached January 10, 1934. On this day, the newly elected President of the United States made a very important decision to abandon the gold standard and issue 3 billion US dollars. Think about it, abandoning the gold standard, in theory, means that he can issue as much currency as he wants. Even if there is no gold in the treasury, he can issue banknotes as long as he wants to. Then someone will ask, if you issue so many words, can you still exchange them for gold of equal value?

Look at the banknotes at this time, they have been separated from gold, and national credit has emerged. , this, we call it currency guaranteed by national credit. Now, when mainstream countries issue currency, they also issue it with national credit as a guarantee.

What are the benefits? The advantage is that it can regulate the economy. When the economy is not doing well, a little more hair can drive economic development. The increase or decrease in this variable will cause a chain reaction of the entire economic aggregate. This is the multiplier effect in economics. Once a country masters this thing, some countries will be fascinated by it. But if it is not well controlled, it will lead to national credit bankruptcy. As a result, many people began to reflect. This reflection is, when issuing currency, is it better to use national credit as a guarantee, or is it better to stick to the gold standard based on the total amount of gold. This question involves the birth of Bitcoin

5. What is the abbreviation of information technology abcd

A: refers to artificial intelligence, B: refers to blockchain technology, C: yes Refers to cloud computing, D: refers to big data.
A It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.

C is a type of distributed computing, which refers to decomposing huge data computing processing programs into countless small programs through the network "cloud", and then processing and analyzing these small programs through a system composed of multiple servers. Get the result and return it to the user.
D: refers to a collection of data that cannot be captured, managed and processed with conventional software tools within a certain time range. It is a massive, large-scale data collection that requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities. High growth rates and diverse information assets.

6. What does blockchain mean?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database that simultaneously divinationIt is the underlying technology of Bitcoin. It is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting). ) and generate the next block.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the renaissance that generations have been striving for. dream.

Puyin Group held the Puyin Blockchain Finance Guiyang Strategy Release Ceremony in Guizhou on December 9, 2016. At the meeting, the blockchain will realize the digital circulation of assets and the blockchain financial transaction model. , and discuss the application of blockchain services and social public industries.

7. What is bnb?

bnb is the abbreviation of Binance Coin. Binance Coin is a digital currency that is welcomed by a large number of users around the world and is among the top digital currencies in the world. The currency trading platform "Binance" is a virtual digital currency issued based on blockchain technology. It runs on an Ethereum-based network, is tokenized in ERC-20, and has a total supply of 200 million cryptocurrencies. Of this amount, $100 million was provided in the ICO. And the platform promises never to issue additional coins. The Binance platform requires a 0.5% handling fee during the transaction process. If you use Binance Coin to pay, you can get certain discounts. Half of the total existing BNB currency will eventually be destroyed. It may be too late for you to enter now.
Extended information:
1. Digital currency (English: Digital currency, also translated as digital currency) is an alternative currency in the form of electronic currency. At present, countries around the world are studying this and discussing the possibility of future issuance, or have already launched issuance testing. At present, the People's Bank of China is the first official institution in the world to express its intention to issue digital currency. It is part of virtual currency. But unlike the virtual currency in the traditional virtual world, its value is affirmed, allowing it to be used for real goods and service transactions, and is not limited to online games. Early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Current digital currencies, such as Bitcoin, Litecoin and Peercoin, are electronic currencies that rely on verification and encryption technology to create, issue and circulate. This currency is based on a specific algorithm. The circulation is limited and encrypted to ensure security. . Its characteristic is the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic approval and gives everyone the right to issue currency.
2. Ethereum is a decentralized, open source, public blockchain platform with smart contract functions. Ethereum (ETH or Ξ) is the native cryptocurrency of Ethereum. As of August 2021, Ethereum is the second-highest cryptocurrency by market capitalizationcryptocurrency, second only to Bitcoin. Ethereum is the most used blockchain. The concept of Ethereum was first proposed by programmer Vitalik Buterin between 2013 and 2014 after being inspired by Bitcoin. It roughly means "the next generation of cryptocurrency and decentralized application platform" and was crowdfunded through ICO in 2014. to start developing.

8. What does blockchain mean?

Blockchain is a term in the field of information technology.

Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". . Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

The Origin of Blockchain

Blockchain originated from Bitcoin. On November 1, 2008, a person claiming to be Satoshi Nakamoto ) published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on the architectural concept of an electronic cash system based on P2P network technology, encryption technology, timestamp technology, blockchain technology, etc., which marked the The birth of coin.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.
