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

II What is blockchain

Blockchain means a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "stupid and unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained".

It first appeared in 1991 and was used by a group of researchers to time-stamp digital documents. So that these documents cannot be tampered with, the blockchain technology looks like a notary.

A blockchain is a distributed ledger that is completely open to everyone. It has a very interesting property: once the data is recorded in the blockchain, it is corrupted and difficult to change. So how exactly does it work? Next, let us first observe the composition of a single block.

Related information

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms.

Ⅲ 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 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”, soOnly then can the money be transferred. 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 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.

IV What are the functions and characteristics of blockchain

1. Any node can Create a transaction, and after a period of confirmation, you can reasonably confirm whether the transaction is valid. The blockchain can effectively prevent the occurrence of double-spend problems.
2. The cost of trying to rewrite or modify transaction records is very high.
3. Blockchain implements two types of records: transactions and blocks. Transactions are the actual data stored on the blockchain, while blocks are records confirming when and in what order certain transactions became part of the blockchain database. Transactions are created by participants using the system in the normal course (in the case of cryptocurrencies, a transaction is created by Bob sending tokens to Alice), while blocks are created by what we call Units of miners are responsible for creation.

IV What information does the blockchain record?

The blockchain is a large distributed ledger, and each block is equivalent to a page in this ledger.
Currently, blockchain blocks mainly record data such as block headers, transaction details, transaction counters, and block sizes. : The block header is the first 80 bytes of the block. The data inside the block is as follows: 1. Transaction details: The transferor and receiver, the amount and the digital signature of the transferor are recorded in detail for each transaction. This is The main content in each block; 2. Transaction counter: This records the number of transactions that occur in each block; 3. Block size: Indicates the size of each block data,...

VI After countless digital currency transactions, can the historical records still be checked?

Yes. Digital currencies such as Bitcoin have two characteristics: 1. Transactions on the blockchain are public: anyone can query all related transactions of an account (address). 2. Blockchain account (address) anonymity: Unless the account owner actively discloses it, it is impossible to know who an address belongs to. The essence of creating a Bitcoin address is to randomly select one from 2^256 private keys (which can be simply understood as the password of the account).

The attribute of Bitcoin is the private key (a string of random characters).

Bitcoin is effectively the same as gold and antiques. Its value lies in its limited quantity (whether natural or man-made). Because the quantity is limited, it is scarce. Everything has value because of scarcity; but like any commodity in any market, the price of Bitcoin is determined by supply and demand. This supply and demand relationship may be affected by major international events. A black swan event may cause a large amount of wealth to be stranded in unofficial channels, and the need to retain wealth through Bitcoin will increase. Bitcoin prices will rise.

VII Blockchain explained in vernacular

1. It is an open and transparent underlying technology system of digital currency. In addition to the private information of the transaction parties being encrypted, other data is open to everyone, and anyone can query and develop related Qingchang applications. The entire system is highly transparent.

4. This ledger is constantly being generated and verified.Computing and storage.

To put it bluntly, blockchain is the general ledger of transaction records of global Internet users. It’s much simpler to understand this way.

Ⅷ What is blockchain technology and how does it change business and financial models

Blockchain technology is a distributed ledger technology that allows Multiple participants work together on a decentralized network to maintain a secure, transparent and immutable record. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improve efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for business activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future

Ⅸ What is blockchain and how to simply understand blockchain technology

What is blockchain

Blockchain is a new technology that uses point-to-point transmission and encryption algorithms. There are countless points in the blockchain, each point represents a user, and the points and When a transaction occurs between nodes, the transaction record will be uploaded directly to the block. The data in the block are linked in chronological order to form the block.chain.

1. Blockchain is also called a distributed ledger. The ledger records the transaction records of all nodes. Each node needs to maintain the development of the blockchain, supervise whether the transactions are legal, and can also work together to Transaction testimony.

2. Encryption technology. The transaction information in the blockchain is public, but the personal information has been encrypted. There is no need to worry about the leakage of personal information. Only with the authorization of the individual can the other party Personal information is queried and the security of personal information is guaranteed.

3. Consensus mechanism. Every node in the blockchain trusts each other. Every user can trade with confidence because the data cannot be tampered with and every transaction must be legal and will not There is a possibility of fraud.

4. In scenarios where smart contracts and blockchain technology are applied, intelligent matching can be used. For example, insurance claims can be automatically settled.

How to simply understand blockchain technology

Blockchain technology can be understood in this way. Xiaohei and Xiaobai are both nodes in the blockchain. Borrowing 1,000 yuan is a transaction, and the data will be stored in the block. At this time, Xiaobai broadcasts to everyone that Xiaohei borrowed 1,000 yuan from him, and Xiaohei also broadcasts that he borrowed money from Xiaobai. He borrowed 1,000 yuan from Xiaobai. Everyone heard the news. On the repayment day, Xiaohei said that he had not borrowed 1,000 yuan from Xiaobai. At this time, everyone came out to testify to Xiaobai that Xiaohei had indeed borrowed money. 1,000 yuan.

In the above example, Xiao Hei and Xiao Bai are equivalent to the two nodes of the blockchain. Borrowing money is a transaction. As long as the transaction is made, transaction data will be generated and uploaded directly to the block. The data in the block is public. Not only can you see it, but everyone in the blockchain can see it. This ensures that Xiaohei will not default and say that he did not borrow money. Everyone in the block will supervise Xiaohei. To repay the money, it ensures the legality of the transaction and mutual trust between each node.
