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 blockchain transaction accounting.

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 the centralized accounting network of Alipay, 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 of the centralized accounting network, transfers only require Alipay to verify the transferOnce the behavior is confirmed and recorded, 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 the Alipay account name according to your personal preferences when applying for an account.

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, check account status and transfer progress.

I want to know about blockchain applications. , you can refer to many books and opinions, including "Blockchain in Pictures", "Blockchain: Reshaping the Economy and the World", "New Economic Blueprint and Introduction", as well as articles from the Binance Community, including comments on the Binance Community platform Also learn more about it, its strength is awesome.

1. What is blockchain

Blockchain, as the name suggests, is composed of blocks and chains. It is a distributed data storage , point-to-point transmission, consensus mechanism, encryption algorithm and other new application models of computer technology. It is a chain data structure that combines data blocks in a sequential manner in chronological order, and is based on cryptography.An untamperable, unforgeable, safe and trustworthy distributed ledger guaranteed by the method.

In 2008, Satoshi Nakamoto first proposed the concept of blockchain and encrypted digital currency in his paper "Bitcoin: A Peer-to-Peer Electronic Cash System". Starting from Bitcoin, blockchain has become the underlying technology of various digital currencies.

2. The working principle of blockchain:

1. Basic concepts include:
(1) Transaction: one operation will change the ledger status once , such as adding a record;
(2) Block: records transactions and status data that occurred within a specified time, which is a consensus and preservation of the current ledger status;
(3) Chain ( Chain): It is composed of blocks connected in chronological order and is a log record of the entire state change.
Understanding the working concept of blockchain, it is not difficult to understand its working principle. Suppose there is a distributed data record book. This record book only allows additions, deletions and changes. Its structure is composed of individual data records. "Blocks" are connected in series to form a linear chain (this is also the origin of the name "blockchain"). To add new data, it must be placed in a new block. The maintenance node can propose a new block. However, a certain consensus mechanism must be used to reach agreement on the final selected block.

2. Take Bitcoin as an example to see how the blockchain works.

Bitcoin blocks are divided into two parts: block header and block body.

3. Core advantages and characteristics of blockchain

1. Decentralization
Block The processes of verification, accounting, storage, maintenance and transmission of chain data are all based on the distributed system structure. There is no centralized hardware or management organization. The rights and obligations of any node are equal. The data blocks in the system are composed of Nodes with maintenance functions in the entire system are jointly maintained.
2. Open and transparent
The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone, and anyone can query the blockchain through the public interface. Data and development related applications, so the entire system information is highly transparent.
3. Security
The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment. , so that trust in "people" is changed to trust in machines, and any human intervention has no effect.
4. Information cannot be tampered
Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system (almost impossible) can be controlled at the same time, otherwise Modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high.
5. Anonymity
Due to the nodeThe exchange between them follows a fixed algorithm, and the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to disclose its identity to make the other party trust itself. Accumulation is very helpful.

4. Classification of Blockchains

Currently, the most mainstream classification of Blockchains is to divide Blockchains into Public Blockchains based on different participants. ), Private Blockchain and Consortium Blockchain.

1. Public chain: Anyone can participate in the use and maintenance, and can obtain effective confirmation of the blockchain. The public chain is the earliest blockchain and the most widely used blockchain at present. , typically such as the Bitcoin blockchain, the information is completely public.

If a permission mechanism is introduced, it will include private chain and alliance chain.
2. Private chain: A company or individual only uses blockchain technology and has exclusive write permission to the blockchain, and the information is not made public. At present, conservative giants (traditional finance) all want to experiment with private blockchains, and the application products of private blockchains are still being explored.
3. Consortium chain: It is a blockchain between the public chain and the virtual chain, jointly controlled by multiple organizations. The use of this chain is managed with authority and can be controlled by managers and also based on The manager's wishes are open to others.
In addition, according to the different usage scenarios and purposes of blockchain, it is divided into currency chains for the purpose of digital currency, property rights chains for the purpose of recording property rights, crowdfunding chains for the purpose of crowdfunding, etc. .

5. Analysis of specific application scenarios of blockchain

1. Information anti-counterfeiting

On May 28, Tencent CEO Ma Huateng spoke at the Guiyang Digital Expo The problem of Moutai anti-counterfeiting has been raised: the anti-counterfeiting method based on cloud-based comprehensive blockchain technology will be much more efficient than traditional anti-counterfeiting methods. In future anti-counterfeiting verification scenarios, users may only need to perform a simple scan with their mobile phone to obtain a large amount of complete information based on different dimensions.

Take Moutai as an example:

Distillery address, production workshop, operating employees, inspectors, factory time, transportation vehicle information and driver information,

The vintage source of raw materials for wine, raw material suppliers, storage warehouse numbers, raw material transportation vehicles and driver information,

All information can be accurately traced, permanently recorded and cannot be tampered with.

The authenticity can be easily verified based on the above information.

2. Food safety issues

As early as November last year, Walmart had cooperated with IBM to ensure food safety by using blockchain technology to track food sources. safety and increase the circulation of food to reduce costs. For large supermarkets such as Wal-Mart, when food safety problems occurred in the past, it took several days to investigate the source of the problematic food.After using this technology, only one piece of product information is needed to achieve accurate traceability. Important information such as food origin, inspector, supplier, logistics and transportation, etc. can quickly detect problems within a few minutes. Currently, products tracked using blockchain include packaging products in the United States and pork in China.

3. Information Security

Blockchain technology is promoting a revolution in information security technology. Three major security threats: man-in-the-middle attack, data tampering, and DDoS

(1) Identity protection

PKI is a common public key encryption used in various communication applications such as email, messaging applications, and websites. technology. However, since most PKI implementations rely on a centralized trusted third-party certification authority (CA) to issue, activate and store user certificates, hackers can attack PKI to fake user identities or crack encrypted information.

CertCoin is the first blockchain PKI implementation, coming from MIT, which removes the centralized certification center and uses the blockchain as a distributed ledger of domain names and public keys.

Pomcor Company: Blockchain PKI implementation path: retain the certification center and use the blockchain to store hash values ​​of issued and activated certificates. Users can verify the authenticity of certificates through decentralized and transparent sources, while also improving network access performance through local authentication of keys and signatures based on blockchain copies.

(2) Data integrity protection

GuardTime has developed a keyless signature architecture (KSI) based on blockchain technology to replace key-based data authentication technology. KSI stores hashes of the original data and files on the blockchain, runs hashing algorithms to verify other copies, and compares the results with the data stored on the blockchain. Any tampering with the data will be quickly detected because the original hash table is stored on millions of nodes.

(3) Protection of critical infrastructure

The "Achilles' heel" of the Internet, DDoS has entered the TB era, and DDoS is still the easiest way for hackers to defeat large targets at low cost. As a weapon, DNS services are the primary target for hackers to carry out large-scale damage, but blockchain technology is expected to fundamentally solve it.

The distributed storage of blockchain makes hacker attacks lose focus. Nebulis is developing a distributed DNS system using the Ethereum blockchain and the InterPlanetary Internet File System (IPFS, a distributed alternative to HTTP product) to register and resolve domain names. The biggest weakness of DNS is caching. Caching makes DDoS attacks possible and is also the bane of centralized governments censoring social networks and manipulating DNS registrations. A highly transparent, distributed DNS system can effectively prevent any entity, including the government, from manipulating records.

IV. Financial Industry

(1) Digital Currency: Improving the convenience of currency issuance and use

For example, foreign Bitcoin and Ethereum, our country currently There are Nuo Compao and so on.

From the use of physical transactions to physical currency and trustWith the rise of currency and the Bitcoin network, more people are aware of the distributed ledger blockchain technology behind it, and it is gradually being applied in many scenarios outside of digital currency.

(2) Cross-border payment and settlement: realize point-to-point transactions and reduce intermediate costs

Transfer and payment. At present, the most mature application of blockchain technology is payment and transfer. Blockchain technology can avoid complicated systems, save the process of inter-bank reconciliation and review, and speed up settlement; using virtual currency does not require the intervention of a clearing house, reducing transaction fee. The clearing procedures of each country are different. It takes 2 or 3 days for a single remittance to arrive, which is inefficient and accounts for a large proportion of funds in transit. No longer going through a third party, point-to-point payment is formed through blockchain technology. Eliminating the need for third-party institutions, you can make payments throughout the day, receive money in real time, quickly withdraw cash, and reduce hidden costs, helping to avoid financial risks. It is timely and convenient.

(3) Bills and supply chain financial business: reduce human intervention, reduce costs and operational risks

Point-to-point value transfer, physical bills or central system for control and verification; intermediary will be eliminated and human intervention reduced. Improved efficiency, smoother financing channels, lower risks, and benefits for all parties.

(4) Securities issuance and trading: realize quasi-real-time asset transfer and accelerate transaction clearing speed

The application of blockchain technology can make the securities trading process simpler, more transparent and faster , Reduce IT systems with repetitive functions and improve the efficiency of market operations. For stocks, blockchain can eliminate paper and pen or spreadsheet records, reduce human errors in transactions, and improve the transparency and traceability of trading platforms. Citi and Nasdaq collaborate to advance blockchain applications.

(5) Customer credit reporting and anti-fraud: reduce legal compliance costs and prevent financial crimes

Customer information and transaction records recorded in the blockchain help banks identify Abnormal transactions and effectively prevent fraud. The technical characteristics of blockchain can change the existing credit reporting system. When banks perform "know your customer" (KYC), the data of customers with bad records will be stored in the blockchain.

Equity crowdfunding: Equity crowdfunding based on blockchain technology can achieve decentralized trust and investors’ returns are guaranteed.

5. Supply chain management

Distributed ledger system, participants track the ownership of assets throughout the process, and can be used to track auto parts when moving between countries and factories.

Toyota is developing blockchain technology solutions for its core parts supply chain operations. Using a large amount of data helps Toyota more efficiently ensure the accuracy of recorded data and can also help manage the supply chain. At the same time, the blockchain supply chain can control warranty, repair goods-related costs and specifications through smart contracts, and transactions throughout the product life cycle are irrevocable.

The shipping industry’s first public solution, deployed by Maritime Transport International (MTI), uses blockchain supply chain technology to share Verified Gross Mass (VGM) information for shipping containers. Information about container VGM is important to ensure ships are properly stowed and to prevent accidents at sea and in ports. VGM data is stored on the blockchain supply chain, providing a permanent record for port officials, shipping companies, shippers and cargo owners. This replaces cumbersome logs, spreadsheets, data brokers and private databases.

Logistics Integrity System Wagonbang Wagonbang launched a blockchain-based financial solution for logistics enterprises, aiming to provide enterprises with reliable financial services. It can not only help drivers solve the problem of loan difficulty, but also change the current situation of lack of integrity in the industry and help build a logistics integrity system. Help build the identity chain of logistics companies and create a trusted data ecosystem for logistics companies. Using a transparent, supervisory, and traceable algorithm model, we screen reliable companies that need financial support and provide them with financial services. On the other hand, at the technical level, various law enforcement departments are linked to jointly punish dishonest companies.

6. Government management

(1) Election

Based on the characteristics of blockchain technology and considering the shortcomings of current election technology, we will build an open source , Blockchain applications for elections, voting and lottery, we call it ElectionChain. We hope to optimize election and voting technology to make voting more open and transparent, reduce human manipulation, and allow voters to verify their election results.

Including identity authentication, multi-chain system, flash investment protocol, consensus algorithm EDPOS, privacy protection, voting mechanism design, decentralized ELC rental market, storage solutions, smart contracts, etc.

(2) Government services

Aiming to realize an e-government digital ecosystem based on blockchain technology and provide citizens with government services and an automated mechanism for the business of various government departments, it must be All areas of national government affairs are combined to form a common information space, including government agencies, economic data, financial transactions and social fields. This ecosystem should also include registries and corresponding software for building smart contract-based applications and platforms for government agencies, businesses and public users.

㈥ Blockchain trading software

Blockchain trading software is a trading platform provided for digital currency enthusiasts and digital currency investors. Then we can start from the following From several aspects
Legally speaking, after the country promulgated the "September Fourth" ban, it clearly prohibited domestic platforms from providing digital currency trading platforms, and digital currency is essentially a It is difficult to clearly define the value of a virtual asset in law (generally speaking, the price of digital currency is affected by a variety of factors) and its value is floating
From the block In essence, the blockchain is actually a decentralized public ledger. Each user in the ledger can be regarded as a node on the blockchain. The fundamental task of these nodes is to maintain the blockchain. The stability of the ledger keeps the ledger data consistent on each node.
From a security perspective, blockchain trading platforms are all in the form of software or websites and are vulnerable to network attacks to a certain extent.
In summary, the blockchain trading platform is unstable.

㈦ What does blockchain mean and what are its applications in cross-border payments

Why is it said that the Internet era is coming to an end and the blockchain era is coming?

Once the blockchain develops, more innovations will burst out. Since the birth of Bitcoin, the first product of the blockchain, many innovations have been born. For example, small-amount cross-border payments, recording transfers between currencies, recording various stocks, registering house property rights, recording program codes, etc.

The steam age liberated social productivity, the electrical age revitalized social collaboration capabilities, and the Internet The era has connected the world together, and the blockchain era will allow us to truly achieve freedom.
