❶ Blockchain and Bitcoin (1)

Blockchain is a type of technology that has been proposed by academic circles for a long time but has only been brought by Bitcoin in recent years. A concept of fire. 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?

I have said before that 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, which consists of three mathematicalExperts suggested that 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. In this way, with multiple ledgers, it would be extremely difficult to tamper with them. Li Bai could safely transfer them 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 this number 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. PlaceThe transaction record that he had tampered with would make errors when decrypted with the correct public key, and was eventually 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:

As we all know, Bitcoin mining takes a long time because of the troublesome math problems. The current cycle is about 10 minutes. This is based on the world Under the premise that hundreds of thousands of mining machines 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 has just been 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.

❷ Comprehensive interpretation of blockchain and Bitcoin, teach you to understand the relationship between the two, and be prepared for trouble

When talking about blockchain, the word "Bitcoin" is often inseparable. Because today's cryptocurrencies are all issued in the name of blockchain, some people easily confuse the two concepts. Next, Kelian Cloud Technology will comprehensively explain the difference between blockchain and Bitcoin and teach you to understand the relationship between the two.

Blockchain is a distributed account. Simply put, it is a decentralized ledger that can be viewed and joined by many people. For example, each block is equivalent to each knot on a rope. When each new transaction enters the blockchain, it means that something has happened. To mark the occurrence of something, a symbol will be used. Tie a knot and record detailed information on the specific knot.

Bitcoin uses the blockchain to realize value storage and transactions. In addition, the technical difficulty of the blockchain itself is not the most difficult. The most difficult thing is its application scenarios and the regulatory issues it will face. .

There are three classifications of blockchain, namely public blockchain, private blockchain, and joint blockchain; the other classification is without authority and permission.

Therefore, cryptocurrencies use blockchain technology, but blockchain technology is not exclusive to cryptocurrencies

When the financial crisis came, some investors chose to invest in cryptocurrencies. In order to avoid corresponding asset risks, thanks to the mechanism of blockchain to solve trust problems, this technology has been applied in financial management and transactions. The main manifestation is that blockchain can track various types of transactions and can also play a role in anti-counterfeiting and traceability in various scenarios. Issues such as copyright, trademark, and academic fraud have been exposed.

In addition, blockchain technology can also simplify transactions, make the entire transaction process open and transparent, and track every link of the transaction event to ensure that both parties have a certain degree of trust.

When "mining", the open source blockchain network can ensure trust and has the characteristics of being non-tamperable. When the networked computers undergo sophisticated algorithms, the correct answer comes out, and the "absentees" You will get mining rewards and can use servers all over the world, but the whole process is still very energy-consuming.

It may be this misunderstanding that causes the public to confuse the concepts of Bitcoin and blockchain. Although more than 90% of current blockchain projects have issued coins, there are very few projects that can actually be implemented. In addition, the crazy mining practice of Bitcoin wastes graphics cards and electricity to a large extent.

Bitcoin is just an open source version of blockchain technology, that is, a network developed for everyone, relying on decentralizationHowever, as a public blockchain, Bitcoin consumes a large amount of computing power due to its mining, resulting in serious power consumption in many countries.

Therefore, for an emerging technology, it is best not to blindly trust or invest in it. Only by recognizing its true purpose can you see everything objectively and be prepared.

❸ How to trade pi coins

1. The global pi coin exclusive trading platform "pi shop" has been launched. Users can go to the official website to sell or purchase pi coins.
2. Pi coins need to be mined with a smartphone. The software does not need to be turned on regularly and has no impact on the performance of the phone. It is a free mining currency.
3.pi coin is an encrypted virtual currency similar to Bitcoin. It is a social blockchain project pioneered by a PhD team from Stanford University.
Extended information
1. Pi Network, referred to as Pi, claims to be a blockchain project that everyone can participate in. How to play Pi is very simple. Just download the APP on your mobile phone and click it every 24 hours to receive mining profits. All Pi coins are mined by users. And when the number of users reaches 100,000, every time the number of users increases by 10 times, the mining revenue will be halved. For example, when the number of users went from 100,000 to over 1 million, production has already been reduced once.
2. According to the current growth rate, the number of Pi users is expected to exceed 10 million in December. According to the description in the white paper, the community will vote to decide whether to halve or stop production directly. Of course, this is the uncertainty that Pi will face next, and it is also a topic of ongoing debate in the community.
1. Pioneer’s basic speed is the same for everyone. It is currently 0.2π/h2. Contributor safety circle bonus. Each person can add up to 5 people to his safety circle (and these 5 people are not required to pass registered with your invitation code). The maximum safety circle reward = 5 × 20% × basic speed = 0.2π/h3, guanxinqian invitation bonus. The more people you directly invite and the more active users you have, the faster the mining speed will be. For example, if I invite 10 people and they are all active, then my invitation reward = 10 × 25% × (basic speed + safety circle bonus). To sum up, Pi does attract people, but the invitation only has a first-level interest relationship; besides, Pi It does not require you to make any financial investment, and it is a truly zero project. Pi does not meet the two characteristics of MLM, so it is not a MLM or a scam.
2. As a mature BitTorrent Currency investors must have an optimistic attitude, a professional spirit, and a fanatical enthusiasm for learning, in order to truly survive in the harsh financial market and achieve long-term development. These trading mentality will lead to losses!

❹ What is the best example of the blockchain transaction process?

1.Definition

Blockchain is like an open network ledger. It originated from Bitcoin and is the underlying technology of Bitcoin. In a Bitcoin transaction, all the information recorded in the transaction is packaged into a "Block" for storage. With the expansion of information exchange, blocks are linked to each other, forming a blockchain.

2. Characteristics

Digital currency represented by Bitcoin is a peer-to-peer electronic cash system. Among them, each transaction will be broadcast to all participants in the network, and will be recorded in the ledger after multiple confirmations. This ledger is the "blockchain". Each participant will have his own ledger. In this way, when false information occurs, it can be broken through mutual verification, thereby ensuring network security.

In the blockchain, every node is equal and there is no centralized management organization. This "decentralization" feature makes the blockchain unnecessary to rely on third parties and its operation is independent. Ability to independently self-verify without any human intervention required. In addition, the blockchain network is open to the world, and anyone can query data through the public port, so the entire system is highly transparent.

3. Application

In short, the blockchain is a trusted database and a reliable "ledger". In the future, it will be used in cross-border payments, securities, loans, voting, etc. For example, in cross-border payments, with the security provided by blockchain, money can be sent to the world anytime and anywhere, thus eliminating many intermediate links and high handling fees.

❺ 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, you can choose according to your needs
Explained from an academic perspective, blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, 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, thereby 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.

❻ Comprehensive interpretation of blockchain and Bitcoin, teach you to understandThe relationship between the two

01 Blockchain is the underlying technology of Bitcoin

Blockchain is a distributed account. In short, it is a decentralized account book that can Viewed and joined by many people. For example, each block is equivalent to each knot on the rope. When each new transaction enters the blockchain, it is equivalent to an event. To mark the occurrence of an event, a symbolic knot is made and the details are recorded on the specific knot

Bitcoin uses blockchain for value storage and transactions. In addition, the technical difficulty of the blockchain itself is not the greatest, but its application scenarios and regulatory issues include three types of blockchain: public blockchain, private blockchain and joint blockchain; the other classification is permissionless and permissions

Therefore, cryptocurrency uses blockchain technology, but blockchain technology does not entirely belong to cryptocurrency

02 When the financial crisis comes, blockchain technology It can prevent counterfeiting, trace the source, and simplify transactions in the financial industry. Some investors choose to invest in cryptocurrency to avoid corresponding asset risks and benefit from the mechanism of blockchain to solve trust problems. This technology has been applied to financial management and transactions. The main performance is that blockchain can track various types of transactions and can also play an anti-counterfeiting and traceability role in various scenarios. Copyright, trademark, academic fraud and other issues have been exposed one after another

In addition, blockchain technology can also simplify transactions, make the entire transaction process open and transparent, track the links of each transaction event, and ensure that both parties have certain rights. Degree of trust

03 The concept of Bitcoin is different from that of blockchain

During the "mining" process, the open source blockchain network can ensure trust and cannot be tampered with. When networked computers run through a precise algorithm and give the correct answer, the "absentees" will be rewarded for mining and have access to servers around the world, but the whole process is still very energy-consuming

Currency Chart B Coin: A comprehensive explanation of blockchain and Bitcoin will teach you to understand the relationship between them. Bitcoin is an open source version of blockchain technology, that is, a network developed for everyone, and it is popular for its decentralized advantages. However, as a public blockchain, Bitcoin consumes a lot of computing power due to mining, which leads to severe power consumption in many countries

Therefore, for an emerging technology, it is best not to be blind Trust or invest and recognize its true purpose in order to see everything objectively and be prepared.

❼ How do ordinary people make money with the blockchain? How do they make money with the blockchain

The emergence of blockchain is a new social trend. It heralds the arrival of a new era of transformation of human society and change of dynasties. The sociological basis of blockchain is based on biological logicThe laws of evolution of nature, society, and technology: distributed, decentralized; from edge to center to edge, from out of control to control and back to out of control. The technical foundation of blockchain is a distributed network architecture. It is precisely because of the maturity of distributed network technology that decentralized, weak-centered, sub-centered and shared, consensus, and shared organizational structures, business structures, and social structures can be effective. Build it up.

First, currency speculation. Coin speculation is the lowest threshold way to make money in the blockchain. The one that everyone is most familiar with is Bitcoin. Bitcoin has increased 40,000 times since its birth. In addition to Bitcoin, there are many digital currencies, such as Ethereum and so on.

Coin speculation is divided into primary market (ICO) and secondary market (exchange). The primary market is like an angel round investment for a certain project, which is usually played by experts; the secondary market is to buy coins on the exchange, just like buying stocks, buy low and go high.

Second, traders. Blockchain is a global market. The price of each currency on each platform and each time period is different. Many people can, like small traders, move from low-price platforms to high-price platforms to sell and make a profit on the price difference. The threshold for this way of making money in the blockchain is low. However, now there are team vendors who use software to operate quickly and accurately.

Third, earn commission from promotion. This method is like a Taobao customer who promotes Taobao product links and gets a commission when the transaction is completed. The blockchain approach is to first register an exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you will get a commission. The threshold for this way of making money in the blockchain is also relatively low.

Fourth, mining. “Mining” in Bitcoin is the accounting process. This process requires grabbing, and if you grab the opportunity to bookkeeping rights, you will be rewarded, and the reward is Bitcoin. This behavior is "mining". Mining requires equipment, professional mining machines. The threshold for this way of making money in the blockchain is slightly higher.

Fifth, technical support. Provide blockchain technology support to some teams and enterprises. This way of making money in the blockchain has a high threshold and requires a technical foundation.

Sixth, open an exchange (trading website). Open a trading website, let everyone trade, and charge handling fees. The threshold is high.

Seventh, develop wallet. The wallet is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain. Mainly business traffic. The threshold is high.

Eighth, do blockchain projects. For example, issuing coins. For example, Ethereum. The Ethereum Foundation raised $18 million in start-up capital and then kept 10 million Ethereum for itself. The way they play is this: first spend the raised funds, and thenIf it's for developers. As developers develop the core technology, Ethereum appreciates in value. Then consume ether coins, spend 9 million ether coins, and the ether coins will circulate. The remaining 1 million Ethereum coins are valued at US$100 million; B. Research blockchain applications. The threshold for this way of making money in the blockchain is very high.

Ninth, basic equipment suppliers. When blockchain becomes popular, whether it is mining or anything else, equipment is needed. For example, the production of mining machines and chips. For example, Bitmain, which produces hardware and software, earns billions of dollars a year. The threshold for this way of making money in the blockchain is too high.

❽ How do I transfer my Bitcoin to someone else’s account?

Many people only know that Bitcoin can be used for investment, but they don’t know that Bitcoin can be transferred like a bank card.

In life, we all have our own bank accounts, and transfers are made between bank accounts. Similarly, Bitcoin transfer is the process of transferring Bitcoins from one Bitcoin address to another Bitcoin address.

If you want to transfer Bitcoin to others, you need to enter your Bitcoin address, recipient address, transfer amount and The amount of the handling fee.

After the payment is confirmed, the transaction information will be broadcast throughout the Bitcoin network. Every 10 minutes, miners will package unaccounted transactions in the Bitcoin network into a block, which completes a confirmation. At this time, the Bitcoin has been transferred to the other party's account.

It usually takes 6 confirmations to ensure that the transaction record cannot be tampered with by anyone before the transfer is truly completed.

1. Enter your own Bitcoin address and the recipient’s address.

2. Enter the transfer amount and handling fee amount.

3. After payment is confirmed, the transaction information is spread throughout the network.

4. Miners will package unaccounted transactions in Bitcoin into blocks.

5. After completing the confirmation, the bitcoins will be transferred to the other party's account.

6. In order to ensure that the transaction record is not tampered with, 6 confirmations are required before the transfer is truly completed.

For example, a person named Xiaowu was mining in the mountains. Today he was lucky enough to find a piece of rare metal worth 10,000 yuan. In order to thank Xiaosan and Xiaosi for lending him tools, he wanted to transfer money to Xiaosan and Xiaosi respectively. Four gave 100 and 400 yuan to express his gratitude. Xiaosi wanted to thank Xiaosan for telling Xiaowu that he wanted to borrow the tools (he just borrowed the tools and got 400 yuan). To express his gratitude, Xiaosi transferred 150 yuan to Xiaosan. Let’s take a look below. Based on how accounts are handled, how Bitcoin is handled.

The Bitcoin transfer fee is a fee paid by traders to miners.It is used to encourage miners to compete for accounting and provide sufficient computing power for Bitcoin to ensure the security of the Bitcoin network. It is also called miner fee in some places. When a user initiates a transfer on the Bitcoin network, he or she generally needs to pay a certain transfer fee to the accounting miner. The transfer fee is generally 0.0001-0.0015 Bitcoins. Due to the limited capacity of blocks to accommodate transaction records, miners will give priority to packaging transactions with high fees, so overpaying fees can be recorded faster. The existence of Bitcoin transaction fees can increase the transfer threshold, effectively prevent the blockchain from being filled with spam information, and ensure that miners still have the motivation to maintain the Bitcoin network after the Bitcoins are mined.

Theoretically, after the block of this transaction record is packaged and 6 more blocks are generated, in principle, this transaction record will be completely confirmed. This transfer is completely confirmed.

Summary: In the Bitcoin network, since there is no center, a variety of new technologies have been adopted in order to achieve safe and effective accounting. The encrypted form of private keys, public keys, and addresses used to prevent the broadcast of secret keys on the network; the UTOX set used to reduce the need to retrieve the entire bill, allowing Bitcoin to flow back and forth in the Bitcoin network like a water pipe; to Fair accounting uses a mining mechanism to allow each miner to compete based on their computing power; in order to balance the output of a block in 10 minutes, the mining difficulty can be dynamically adjusted based on the computing power of the entire network. All these technologies revolve around accounting, and the main block data of the Bitcoin blockchain is also such a piece of transaction data. There is no Bitcoin itself, but only UTOX based on a few satoshis; there is no account itself, there is There are just three forms of a string of numbers (private key, public key, address).

❾ How do I sell 10 Bitcoins?

1. Directly buy and sell Bitcoin or other digital currencies in RMB

Through the "OTC" platform:

1. Buy directly in RMB

2. Sell the currency you hold and exchange it for RMB

This trading model is commonly known as "OTC". It is a direct transaction between individuals and the platform provides guarantee. It’s a bit like Taobao, which specializes in buying and selling Bitcoins. However, if you encounter a scammer during a transaction, it is still a troublesome thing. Therefore, it is recommended that when choosing a platform, you should not only consider whether it supports RMB transactions, but also whether it has Chinese customer service. If there is a problem with the transaction, it can be convenient. Contact customer service in Chinese and apply for arbitration.

2. RMB trading in other currencies

Due to current domestic policies prohibiting direct RMB transactions, most currencies in the currency circle cannot be directly bought and sold in RMB. There are three common currencies that can be traded directly in RMB: Bitcoin (BTC), Ethereum (ETH), EOS, USDT, etc. Therefore, in the process of virtual currency transactions, we often use USDT as an intermediary. USDT is a U.S. dollar legal tender token that always maintains a 1:1 exchange rate with the U.S. dollar. It is equivalent to the U.S. dollar in the blockchain, and its price is relatively stable. Everyone calls it a "stable currency." To understand it simply: you can think of USDT as equivalent to the US dollar.

So it is recommended for newcomers to the currency circle to use it directly The Huobi Professional Platform is very convenient for mainland users to register and authenticate. The website is also in line with the habits of mainland users. At the same time, it can be used to buy and sell coins in RMB in one stop. Most people will directly convert RMB into USDT and then conduct transactions in other currencies.

Due to policy issues, Huobi had to move its business Split into two
