区块链交易逻辑是什么,区块链交易逻辑分析

区块链交易逻辑是一种分布式数据库技术，它可以记录、管理和存储交易数据，以支持数字货币的流动性和安全性。本文将介绍区块链交易逻辑的三个关键词：去中心化、可信性和安全性。

去中心化是区块链交易逻辑的核心概念。它是一种分布式账本技术，它没有中央控制机构，而是由网络中的节点共同维护。每个节点都可以参与到区块链交易逻辑的管理中，从而实现数据的安全可靠性。因为没有中央控制机构，所以区块链交易逻辑可以实现去中心化，从而提高交易的安全性和可信性。

可信性是区块链交易逻辑的另一个关键词。它是一种分布式账本技术，它可以记录、管理和存储交易数据。它使用共识机制来确保交易的可信性，这意味着所有参与交易的节点都必须达成一致，以确保交易的可信性。此外，区块链交易逻辑还使用加密技术来确保交易的安全性，以防止未经授权的访问。因此，区块链交易逻辑可以提供可靠的交易服务，从而提高交易的可信性。

安全性是区块链交易逻辑的另一个关键词。它使用加密技术来保护交易数据，以防止未经授权的访问。此外，它还使用共识机制来确保交易的安全性，从而保证交易的完整性和可靠性。因此，区块链交易逻辑可以提供安全可靠的交易服务，从而提高交易的安全性。

总之，区块链交易逻辑是一种分布式账本技术，它可以记录、管理和存储交易数据，以支持数字货币的流动性和安全性。它的三个关键词是去中心化、可信性和安全性，它可以提供可靠安全的交易服务，从而改善数字货币的流动性和安全性。

Ⅰ What is the principle of Bitcoin and blockchain

Bitcoin is an electronic cash system implemented using peer-to-peer technology, which allows one organization to directly conduct transactions with another organization Pay online without the need for an authoritative clearing agency in the middle.
In the world of Bitcoin, if you want to own Bitcoin, you need to apply for a Bitcoin address, just like when you go to a bank to deposit money, you need to open an account. Then, you have this account and yourself. Account, you can make deposits to your account, and others can also transfer money to your account. When you need to withdraw money or transfer money to others, you need to present a key that can open this address, which is your private Key, just like you need to provide a password when withdrawing money at an ATM.
Unlike the legal currency issued by banks, the issuance of legal currency is uniformly managed by the central banks of various countries. Everyone believes that the central bank is reliable and will not record wrong accounts or be attacked. However, the issuance of Bitcoin does not require an authoritative institution such as the central bank. It allows a transaction to be settled directly from one organization to another, eliminating the need for settlement by an authoritative institution, improving the efficiency of transactions and settlements, and saving transaction costs. costs, especially the costs of cross-border transactions.
The blockchain is composed of multiple blocks. Each block is composed of a block header and a block body. Each block header contains the meta-information of the block and also contains a pointer to the previous block. A pointer to the block header hash value. This pointer is key information to prevent the blockchain from being tampered with. The block body contains the transaction information of Bitcoin. The first transaction is a special transaction, which is the reward given to the mining node. This is also the only way to generate Bitcoin, that is, the way to issue Bitcoin. The rest Transactions are all transfer transactions. Bitcoin is paid from one address to another address. This is also the only way to realize the transfer of Bitcoin value. To sum up, Bitcoin only has two methods: mining and transfer. After Bitcoin is generated, it can only be transferred from one person to another, but cannot disappear out of thin air. Moreover, the total amount of Bitcoin issuance is constant, with a total of 21 million. , is a general currency.

II A brief discussion on blockchain: How to use blockchain for transfer transactions

In life, we all have our own bank accounts, and transfers are made between bank accounts. Similarly, digital currency transfer is the process of transferring Bitcoins from one Bitcoin address to another Bitcoin address. Then if you want to transfer money to others, you need to enter your Bitcoin address, recipient address, transfer amount and handling fee amount on the Bitcoin trading platform, Bitcoin wallet or Bitcoin client. After the payment is confirmed, the transaction information will be broadcast throughout the Bitcoin network. Every 10 minutes, miners will package the unaccounted transactions in the Bitcoin network into a block. This completes a confirmation. At this time, Bitcoin It has been transferred to the recipient's account. Generally, it needs to be confirmed 6 times to ensure that the transaction record cannot be tampered with by anyone before the transfer can be truly completed.

We talked about the transfer fee above, but how much is the fee for one transfer?

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. Some Sometimes we also call this fee a mining fee. When a user initiates a transfer on the Bitcoin network, a handling fee is unavoidable. Generally, it is 0.001-0.0015 Bitcoins. Due to the limited capacity of transaction records that can be accommodated in blocks, miners will give priority to packaging transaction records with high handling fees. , so a little more handling fee can be recorded faster.

Ⅲ Core logical issues that need to be paid attention to in the blockchain

Core logical issues that need to be paid attention to in the blockchain
Blockchain is a decentralized, deintermediated, point-to-point transaction processing The system is a distributed account system that is verified by the entire network, recorded by the entire network, irreversible, difficult to tamper with, traceable, and open and transparent. These are the two main contents of the current definition of blockchain. But if you follow the standards of decentralization, deintermediation, and peer-to-peer transactions, and use blockchain as many people say, it is basically not the case. Because there are almost no truly decentralized blockchain applications. Many people say that the blockchain will be a machine of trust and the Internet of value. The blockchain will recreate production relations, economic organizations, and operating models. It will subvert the legal currency system, subvert the double-entry accounting method, and even create a place where everyone can issue money. A new society in which everyone has his own currency, everyone’s own finance, and everyone’s self-organization. Is it this way?
Today I want to share with you how we view the blockchain in such a hot atmosphere, how to grasp its core logic and avoid major subversive mistakes.
This is mainly based on the Bitcoin blockchain.
The first is whether encrypted digital currencies such as Bitcoin can become real currencies, and whether this type of digital currency can subvert the legal currency system.
We know that currency has existed in human society for thousands of years and has continued to evolve, from the initial physical currency to regulated metal currency, to paper money under the metal standard, and then to credit currency without the metal standard. What are its logic and rules as it continues to evolve to today? This is what we need to accurately grasp.
In the evolution of currency, especially after the introduction of paper money, people gradually discovered that currency has more and more functions and its influence is growing, but its most important and core function is the measure of value.
To give full play to the function of value scale, the most basic requirement is that the currency value must be relatively stable. To achieve a relatively stable currency value, theoretically, a country's currency total must correspond to the scale of monetizable wealth that can be protected by law within the country's sovereignty. In other words, the total amount of money and the scale of wealth must correspond.
How to correspond? It is impossible to completely correspond to each one, so the concept of an intermediary target is introduced. There is a concept of a general consumer price index for the whole society, the so-called CPI concept. When a country's CPI changes, that is, the fluctuation of the inflation rate, is within our target range and within a controllable level, we consider the price or currency value to be relatively stable.
Here we are talking about relative stability, because the bigger a country is, the less likely it is that prices will be absolutely stable, and at the same time, fluctuations must be controlled within a certain range and not get out of control. When your inflation rate is controlled within a certain rising range, it means that the currency is devaluing to a certain extent. What are the benefits of currency devaluation? It can inhibit deposits, encourage investment and consumption, thereby playing the role of monetary policy and promoting economic development. It is precisely because the monetary aggregate can be artificially controlled and there is room for control that monetary policy came out. Monetary policy, like fiscal policy, has become one of the two major policies for national macro-control. But there is a premise: currency depreciation or inflation cannot get out of control. Once it gets out of control, the people at the bottom cannot survive, violent social turmoil will occur, and governments or dynasties will change. There are many such examples in history.
Today, we are also faced with many temptations in monetary policy, tempting people to overissue currency. It is precisely for this reason that some people have begun to say that your currency system is wrong. If humans can control it, there will be corruption and unfairness. Can we use technical means to form a currency system that some people cannot interfere with? This also gave birth to encrypted digital currencies such as Bitcoin.
But we must know that the law of currency development is that currency must gradually separate from wealth and become a counterpart to wealth. In this way, we can use the total amount of currency to completely correspond to wealth, and at the same time, there will be certain controls. room. Therefore, something like gold, which has strong physical properties and is greatly restricted by its reserves and mining and processing, needs to be separated from currency and become the counterpart of currency. Of course, it may have a great store of value function. In this way, currency has developed to this day and has become what people call credit currency or currency guaranteed by national credit. I personally feel that this term is not necessarily accurate, because the debts of many countries' governments are getting larger and larger and will never be repaid, so it is a bit far-fetched to call it a credit currency. Strictly speaking, today's currency is legal currency or sovereign currency. It means that the total currency amount of a country must correspond to the scale of wealth that can be protected by law within the country's sovereignty. It is precisely because of this that everyone will find that today we can no longer use physical currency and use gold as currency. At the same time, let’s go back to the private issuance of currency, and the denationalization of currency is also not allowed. Today, many cryptocurrency enthusiasts cite a sacred scripture, saying that Mr. Hayok said that currency shouldDenationalization. But Hayok's idea has not been implemented to this day, because it violates the trajectory and logic of currency development.
Let’s take a look at Bitcoin. Bitcoin uses very complex technology and rigorous mathematical operations, but its monetary system is highly imitated by gold, so we can see that its total amount is fixed, and it is reduced by half every four years, because gold reserves are fixed. , the easier it is to dig out first, and the later it is, the harder it is to dig out. Therefore, the new output is theoretically lower and lower, and one day it will be dug out. The same is true for Bitcoin, with a total of 21 million. The content contained in every ten minutes is set by the system. It will be automatically halved every four years, and it will basically end by 2140.
You may have seen that there are some problems with the current credit currency, but if you think about going back in time and designing a new currency system based on gold, it itself violates the logic and rules of currency development. From this perspective, it It cannot be a real currency. These things can only be a kind of online virtual assets, or tokens or business district coins used in a business district. It does not necessarily have no value at all. Does it mean that gold has no value without currency? Still valuable, as long as you have real application scenarios.
Everyone will see things like Bitcoin. As long as it is in the Bitcoin circle that everyone recognizes, it also has a certain basis for circulation and use. Just like the current legal currency in China is RMB, it does not mean that there are no company meal tickets or shopping coupons in shopping malls.
Once it is determined that the currency belongs to the business district, its use within the business district must be strictly controlled and cannot be used outside the business district. Otherwise, it will challenge the application of legal currency. If it affects legal currency, it will definitely be subject to national sanctions. Supervision. As long as you get bigger and pose a threat to the legal currency system, it will definitely regulate you. Today you will see that this trend has already emerged, and countries are gradually beginning to strengthen the supervision of cryptocurrency. This is an issue we need to pay attention to.
Everyone knows that although Bitcoin imitates gold, its design is much stricter than gold, because it tells you how many coins it produces every ten minutes, and it cannot be adjusted manually. However, strictly limiting the output every ten minutes will cause a serious separation between the supply of money and economic development and changes in wealth, and then the value of the currency will be difficult to control at all. If Bitcoin is really like the one thousand US dollars in early 2017 to nearly 20,000 US dollars in November, some people say that it may be 100,000 US dollars or 200,000 US dollars in the future. If a Bitcoin is used as a currency, think about the fluctuations in the entire currency value. How big. Because if your stock price rises quickly, your stock price may drop significantly as well. More importantly, Bitcoin did not attract everyone's attention at the beginning. Many students played it in the dormitory. Because it was not valuable, the Bitcoin keys dug out in the early stage were lost and became death coins, and this could not be activated. About 17 million Bitcoins were mined today, of which 37.8 million were death coins. The original 21 million were very limited. If you remove another 37.8 million coins, the supply of this coin would be even greater. It’s limited. What's more, if it really goes upIf there is space, many people will soon use it not as payment for coins, but as storage and collections, and the supply will be even more limited. So from these perspectives, people who are really engaged in currency will find that it is actually difficult for it to play the role of currency. It is more like a counterpart to currency, and it can be used as a store of value like gold.
Second, let’s see whether blockchain like Bitcoin can subvert the world and what role it can play.
Bitcoin places great emphasis on decentralization, deintermediation, and peer-to-peer. But how to achieve decentralization? There must be a need for computers in society to join in running together and maintaining rules together. Because if the host that the system runs on is a host from a certain company, it is very easy for you to change the rules of the system. How can you say it is decentralized? Therefore, Bitcoin must require computers in society to participate in its operation. If everyone wants to participate, the first premise is that the system must be open source, and the automatic download can run immediately. It does not require a lot of testing to run online. Otherwise, it will not be able to cope with the social and global franchise system.
The second rule must be built into the system. The so-called encoding is the rule. Everyone is maintaining this rule while running this system. In the future, without the consent of more than half of the participating nodes, even the person who maintained the code at the beginning will not have the right to change the rules of the system. But it is not easy to achieve this. It requires consensus and encouragement. The final result is that the more we pursue decentralization and intermediation, the more we pursue decentralization and the formation of a completely closed network system. What do you see today that can run on Bitcoin? There is only one thing, Bitcoin. And where did Bitcoin come from? It is a chain-generated asset that is mined and has nothing to do with the real world. Because of this, it can achieve any change from the initial coin production to the coin. Each account is monitored by the entire network, which is difficult to tamper with and can be traced. Precisely because each account can maintain its authenticity, we can do it without knowing who the person behind the account is. As long as we ensure that the account is genuine, we can do transactions.
As a result, someone deduced on this basis that using the blockchain, you can do transactions without knowing who the other party is. Is this really the case?
Bitcoin’s decentralized and peer-to-peer transactions have strict prerequisites. It must be in a closed network system from the beginning. The assets traded can only be chain assets, and it is impossible to send real wealth to it. How can this solve real problems when real wealth cannot be put into operation? Therefore, Bitcoin still needs to be converted into legal tender today to realize its value. If it cannot be converted into fiat currency, its value will be significantly reduced. More Bitcoin interpretation: www.yangfenzi.com/tag/bitebi
The problem is that the Bitcoin blockchain itself has no exchange function, only mining, currency production and internal point-to-point transfers. There is no exchange function. To exchange, you must get out of the Bitcoin circle and enter a plug-in trading system. So you will see that a lot of digital goods were released todayBitcoin exchanges, if there is a problem with the exchange, it does not mean there is a problem with the Bitcoin system. The Bitcoin system is still safe today, provided that it is a completely closed system that is not affected by outside influences.
There is another one, the rule of Bitcoin producing coins is how many coins every ten minutes. It forgets that money and finance are connected. Finance requires loans to earn interest or investment dividends. Let’s take a look at the rules for Bitcoin’s interest-earning currency production. Are there any foreign currency production rates for loan interest-earning and investment dividends? No, it must be exchanged for legal currency. Only through legal currency can the needs for loans and investments be realized. If the Bitcoin blockchain is strictly used, the financial functions will be greatly affected, which is what we need to see.
Because of this, our Bitcoin blockchain brings a problem, which is that everyone imagines it very well. It is a brand new thing, but it is a completely closed system and cannot actually solve our real problems.
Therefore, the designers of Ethereum said that this would not work, and that it would become an online game. Practical problems must be solved in this thing, so Ethereum added a smart contract on which some private work can be done. However, the addition of smart contracts has broken the traditional isolation. Today, the security of Ethereum is weaker than that of Bitcoin.
At the same time, Bitcoin and Ethereum insist on network-wide verification and network-wide recording. When the volume increases, the storage space of the entire network will occupy a very large space, the efficiency is very poor, and the resources consumed are increasing. Today, some people are exploring whether further improvements can be made. For example, does it have to be verified and recorded across the entire network? Aren’t the existing banks just in two places and three centers, and haven’t there been any big problems? Can we select a certain number of core nodes here, such as 21 nodes or 31 nodes? EOS or something similar, the so-called blockchain 3.0, basically uses smaller nodes, and no longer records and stores the entire network at the same time.
This raises another question: Who will choose these core nodes? If one of your parties designates the core node, wouldn’t that mean there is no decentralization? So everyone is discussing whether we can compile a system that is decentralized when selecting nodes. It is still being discussed, and it is even further said that mining requires huge energy consumption. Is mining necessary? Similar to these aspects, blockchain is still being explored today.
So, at this point we can draw a conclusion that blockchain is still in its early stages of research and development. We may think that it has great room for development, but we should not easily say that it can subvert this and subvert this. That, at present, we can see that the real applications are very limited, and a lot of exploration is still needed.
It is from this perspective that I have been calling on everyone since last year to treat digital currencies and blockchain rationally. Judging from the current development stage and application scenarios, blockchain research and development will have two major branches: One branch will continue to focus on the development of the underlying technology, which is the research and development of the public chain, and continuously improve it. But you must know that the research and development of underlying technology and public chains requires a lot of long-term research and development.It's very difficult. We hope that someone will continue to follow this path to develop and make breakthroughs in a down-to-earth manner.
Another branch is application. This application should not think about a blockchain like Bitcoin, but focus on mining and coinage. I have been calling on everyone to find applications outside the paradigm of Bitcoin mining and coinage. What application are you looking for? Then stop pursuing decentralization and deintermediation. What you pursue is distributed processing of information, continuous encryption, traceability, non-tampering, etc. Prioritize these aspects to solve practical problems. From this aspect, we can see that there are many application scenarios, because this society is accelerating towards an information society.
First, we can look for other things that are not so closely related to our property or claims and debts. You will see that people like BAT are now making online games, whether they are raising cats or pets. They are online applications and do not involve real property or laws and regulations. The second is to do public welfare undertakings, such as donations. Money and goods go out in one direction and do not need to come back. There is no buying and selling relationship or loan relationship, but people care about whether this thing goes according to my wishes, so it can be traced and tracked. .
Going a step further, many of our administrative institutions now have a large number of documents, contracts, images and other things in government affairs. Can we help them push them to the chain and run them online to ensure that these things are authentic and legal? Yes, irreversible and can be checked at any time. This is all possible. Going one step further may be the future development towards the integration of so-called computer networking, information networking and value networking, that is, the integration of the physical Internet of Things. The so-called real solution to our practical problems may still take a while.
This is the communication I want to have with you. Blockchain is an integration of multiple technologies. Bitcoin is the first application, and it is also a very complete closed system so far. It is very safe, but it cannot solve practical problems. More and more people are discovering that the current Bitcoin blockchain or similar blockchains have an incompatible triangular relationship of "decentralization, high efficiency and security". Therefore, we must seek truth from facts and focus on solving real-life problems. , pay attention to the use of applications, and jump out of the paradigm of the Bitcoin blockchain. This is a basic point of view that I will share with you today for your reference.

IV Blockchain Principle

Blockchain is a technology, but it is not a single technology, but the result of the integration of multiple technologies, including cryptography, Mathematics, economics, network science, etc. You can think of it as a distributed shared accounting technology, or as a database, but this database is jointly maintained by all nodes on the chain, and each node has a ledger, because all nodes The ledgers are consistent, different nodes can trust each other, and there is no doubt about the data, so everyone says that the blockchain has technically achieved trust. For detailed professional technology, you can consult some professional technology companies. For example: Jinbo Technology, which focuses on developing blockchain-related products, has a professional R&D team and complete after-sales service. You can call for consultation.

Ⅳ What is the principle of blockchain

I saw some answers arguing about the definition of blockchain, and suddenly realized that my answer explaining the principle was actually talking about Bitcoin. , since the industry does not have a particularly clear and unique answer to the definition of blockchain, here are the characteristics that a "blockchain" should have that I have summarized based on the papers I have read:

1 .Using a data structure in the form of "hash chain" (explained below) to save basic data

2. Multiple nodes participate in system operation (distributed)

3. Reach a consensus on the consistency of basic data through a certain protocol or algorithm (consensus protocol/algorithm).

Since Bitcoin is currently one of the most typical and influential applications of blockchain, after understanding how Bitcoin uses blockchain, you can then understand other various forms of blockchain applications. It will be much easier.

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

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 or her 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 the blockchain, money can be sent to the world anytime and anywhere, thus eliminating many intermediate links and high handling fees.

Ⅶ This is what transactions on the blockchain are like

Transactions on the blockchain are actually very simple and not mysterious. To understand transactions on the blockchain, let me first look at a transaction in daily life.

What would happen if the payment method of this transaction was moved to the blockchain? Before talking about blockchain transactions, let’s briefly talk about blockchainWhat is the transaction accounting of the blockchain?

1. What is blockchain

Blockchain is simply B’s ledger. A block is a page in this ledger, used to record transaction information. For example: On December 14, 2017, a computer was sold and a profit of 5,000 yuan was made. All blocks are strung together in order to form a blockchain, that is, a ledger.

2. Characteristics of blockchain

Blockchain is a distributed accounting network. If it is difficult to understand, you can compare it with Alipay, a centralized accounting network, as shown below: < /p>

The central approach is like having only one accountant. Only this accountant knows how the transaction is going. Distribution is like a bunch of people keeping the same account and making a transaction, everyone knows about it. A relatively small group with only one person knowing the information. An information disclosure and transparency.

3. Blockchain transaction accounting

In Alipay’s centralized accounting network, transfers only require Alipay to confirm and record the transfer behavior, and then the transfer can be completed and recorded. .

In the blockchain of the distributed accounting network, each transfer transaction will be sent to each node and confirmed by them before the transfer can be completed and recorded.

To put it simply, one person has the final say in a centralized accounting network, while everyone has the final say in a distributed accounting network. If anyone lies or commits fraud, they will be able to spot it quickly because everyone has a copy in their hands. Exactly the same ledger.

If A chooses Alipay to transfer payment to B, the operation process is as follows: open Alipay -> click on transfer -> enter the other party's Alipay account -> enter the transfer amount -> click to confirm the transfer -> enter the password. Whoosh, the money was in account B.

If A chooses to pay B with BTC, if the current 1 BTC = 100,000 yuan, then A needs to pay 0.05+0.001 = 0.051 BTC to B, of which 0.001 BTC is the mining fee.

The operation process is as follows:

In terms of operation, the transfer process is similar. Maybe you don’t understand what an address is? What the hell is the mining fee? What are those 6 confirmation numbers? No rush, come one by one.

1. Blockchain address

The address can be understood as B's Alipay account. When A transfers money to B, he naturally needs to know the other party's "account number" so that he can transfer money there. The following is a BTC address:

It is a string composed of numbers and letters.

How is this address generated? It is generated by the public key through a one-way hash function. You can leave it alone and it is automatically generated. Unlike Alipay, you can choose an Alipay account according to your personal preferences when applying for an account.Number name.

What else can the address be used for? To check the "account" balance and transfer transactions, you can check the balance and transfer records under any valid BTC address on the btc.com website, as shown in the following figure:

2. Transaction confirmation number

In the blockchain distributed accounting network, every transfer transaction is confirmed by a node in the network, and one transaction confirmation number is recorded. However, it will take a long time for the transfer to take effect only after confirmation from all nodes in the network. Therefore, in the BTC network, based on design calculations, when 6 transaction confirmations are obtained, the transaction can be considered very safe, the transaction takes effect, and the transferred BTC can be received.

3. Mining fees

Mining fees are the "tips" paid by A to the BTC network provider when A transfers money to B to encourage them to provide services for the BTC network. The "tip" can be adjusted. The more "tip" you give, the faster the transfer speed will be.

4. Transaction progress query

BTC transfer generally takes 0.5~1h. Faced with such a long time transfer, it is inevitable to want to check the transfer progress to comfort the anxious mood. How to check it? ?

You can query by address, as above. It can also be queried by TxID.

What is TxID? TxID is the abbreviation of transaction ID, which translates to: transaction ID.

When the transaction information is packaged and sent to the network, a TxID will be generated, but it is used to view transaction-related information, somewhat similar to a receipt. The status of any transaction ID can be queried through the btc.com website, as shown in the query result below:

At this point, you can easily transfer transactions on the blockchain and check the account status and transfer progress.

Ⅷ What is the working principle of blockchain

Blockchain that is very popular recently What kind of technology is technology? Blockchain technology is considered to be the brightest star in financial technology, and it may continue to develop in the future. It has many characteristics, including the distribution of data and the trust of data. Degree and collective consensus mechanism, the most important ones are openness, transparency, anonymity and privacy, which are very distinctive features. Based on the data in these blockchains, we can derive some basic information about contemporary society.

Blockchain technology is such a secure and scientific database. It can be simply understood as an authoritative database. The basic content in itThe content is all true and has been verified and reviewed by others. In terms of financial technology, it will be very easy to find some desired data, which is very good for people doing business.

Ⅸ 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, 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.
