『一』What is the popular explanation of blockchain

Blockchain is a technology based on which many applications are produced, including data and information related In all industries and businesses, Bitcoin is one of the most well-known applications.

The popular explanation of blockchain is that if you buy a lipstick online, you first find the product you like and place an order with the seller, first give the money to the intermediary platform, and wait until the seller ships the goods and the buyer confirms receipt. In the future, the intermediary platform will transfer the money to the seller. Because of the trust issue, buyers and sellers rely on the intermediary platform. As a decentralized distributed ledger database, the blockchain focuses on removing this intermediary platform while solving the problem of trust at the same time. question.

Blockchain Precautions

Before investing in a project, you must do enough homework and learn more about the future development prospects of the project through various channels. Including the profit model, valuation space, and project team, all need to be understood in detail. It would be terrible to invest money without knowing what the project is about.

Never take advantage of it. The blockchain industry has just emerged and the market is still blank, so there will be many good projects related to it. We must not invest all our funds in one project, even if this It doesn’t matter if the project is very good. You must know that any project may not succeed, so you must learn to diversify your investments. Diversifying your investments means diversifying your risks.

『二』Blockchain explained in vernacular

Blockchain explained in vernacular is:

A decentralized distributed ledger database . Decentralization means that it is different from the traditional centralized method. There is no center here, or everyone is the center. Distributed ledger database means that the recording method is not only to store the ledger data in each node, but also in each node. The data of the entire ledger will be shared and copied synchronously.

Generally speaking, a blockchain system consists of a data layer, a network layer, a consensus layer, an incentive layer, a contract layer and an application layer.

Among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms, etc. ; The consensus layer mainly encapsulates various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and Smart contracts are the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain.

In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power and flexible programmable smart contracts are the most representative of blockchain technology. sexual innovation.

『三』 The terminology of blockchain

Blockchain is a series of verified blocks, each of which is connected to the previous block.Connect to the genesis block.

1. Blockchain (BlockChain)

Blockchain is a series of verified blocks, each of which is connected to the previous block. to the genesis block. Blockchain is the underlying technology of digital currencies such as Bitcoin. It is a decentralized distributed shared ledger. Blockchain, artificial intelligence, and big data are known as the three major directions of financial technology. Ma Chajue

In 2009, he built an open source project for the Bitcoin system and officially announced the birth of Bitcoin. But when Bitcoin gradually became popular, Satoshi Nakamoto quietly left and disappeared from the Internet.

『四』What does blockchain mean and how to understand it

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

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

Notes

1. Blockchain Originated from Bitcoin, on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, The architectural concepts of electronic cash systems such as timestamp technology and blockchain technology mark the birth of Bitcoin.

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

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations have been striving for, Puyin Group launched the On the 9th, a Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou. At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the application of blockchain services and social public industries will be discussed. Explore.

『Wu』 Popular explanation of what blockchain is

Blockchain is a distributed and decentralized computer technology. Blockchain is not equal to Bitcoin, it is just an underlying technology invented to realize the digital currency of Bitcoin. Blockchain can be used in a wider range of applications. In addition to digital currency, it can also be used in financial aspects such as P2P lending, global payments, microfinance, electronic payments, and remittances. It can also be used in intellectual property rights., elections, notarization and other aspects of people's livelihood, there are huge prospects for future development.

So, what is distributed and decentralized? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer. Only then has the legal process been completed. What if blockchain technology is used? As long as two people agree to get married and then post a message in their circle of friends, the marriage process is completed, and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses. They may be scattered around the world, but their mobile phones will help you record the information and tell others who want to know the situation.

Characteristics of blockchain

1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.

2. Openness. The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent.

3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.

4. Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.

『Lu』 What is blockchain in simple terms

Blockchain is a term in the field of information technology. Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeability", "whole process traceability", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". Blockchain has entered the public eye and become the focus of society. From a technological perspective, blockchain involves many technological issues such as mathematics, cryptography, the Internet, and computer programming.
Extended information:
From an application perspective, in short, blockchain is a distributed shared ledger and database, with the characteristics of decentralization, non-tampering, full traces, traceability, collective maintenance, and openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for establishing trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry and achieve cooperation, trust and coordinated action among multiple entities.
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. Blockchain is an important concept of Bitcoin. Essentially, it is a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks associated with cryptographic methods. Each data block contains a batch of Bitcoin network transaction information to verify the validity of its information (anti-counterfeiting) and generate the next data block [8]. In fact, the word blockchain does not appear in the original English Bitcoin white paper, but blockchain. In the Chinese translation of the earliest Bitcoin white paper [9], blockchain was translated into blockchain language. This is the earliest time when the Chinese word "blockchain" appeared.

A popular explanation of what is blockchain

What is blockchain Popular explanation,Blockchain is a hot topic nowadays, and its development speed in China is getting faster and faster, but many people still don’t know what blockchain is? Now I will give you an easy-to-understand explanation of what blockchain is!

Popular explanation of what blockchain is 1

Generally speaking, blockchain is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can trade directly. There is no need for any intermediary, everyone has a backup, even if your copy is lost, it will not be affected.

Suppose you have a ledger at home, and your parents give you your salary and ask you to record it in the ledger. You misappropriated more than ten yuan privately because of your greed, and no one else knew about it. But the way to solve the problem with blockchain is to keep accounts with the whole family. Not only you are keeping accounts, but your father, mother, brother, sister, younger brother, sister, etc. are all keeping accounts. They can all see the general ledger, and you It cannot be changed, and neither can others.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain technology has been widely used in different industries. Such as product traceability, copyright protection and transactions, payment and settlement, Internet of Things, digital marketing, medical care, etc.

Common questions in blockchain engineer interviews

What do you think the block in blockchain technology means?

The blockchain consists of information about all financial transactions. A block is nothing more than a list of records. When these lists are combined together, they are called a blockchain. For example, if an organization has 100 ledgers, their combination is called a blockchain, and a single ledger will be considered a single block.

Why is blockchain a trustworthy approach?

There are many reasons to trust blockchain. The first reason is that it is compatible with other business applications because it is open source. Secondly, it is secure because it was developed for online transactions, so the developers pay special attention to its data synchronization while keeping it safe. Because the type of business it holds is unrelated, it is easy to consider distinguishing chains when choosing.

How much do you know about blockchain?

This is a technology that was actually designed for Bitcoin and later heavily promoted for the multiple benefits of monitoring and recording all financial transactions on the network. This is a trusted method that is currently being used by many organizations. Since everything is secure and open source, it is easy to gain trust in the long run.

Utilizing blockchain in an organization, if there are specific technical requirements for that network?

No specific conditions of use. However, the network must be a peer-to-peer network under the relevant protocol. It actually just validates new blocks and helps organizations stay in sync without having toInvest in third-party apps.

What is encryption? What is its role in blockchain?

Data security is always very important. Encryption is basically a way to help organizations keep their data secure. In this technique, data is encoded or altered to some extent by the sender before being sent to the network. Only the receiver can know how to decode it. This practice is very useful in blockchain because it increases the overall security and authenticity of the block and helps ensure that the block is secure.

What types of records can be saved on the blockchain? Are there any restrictions?

There are no restrictions on any type of records in the blockchain approach. Currently, many organizations around the world are using this approach, and the fact is that medical transaction records, organizational related events, administrative activities, transaction processing, identity management, document records are all common record types that can use blockchain. And record keeping is not limited to these applications..

What is double spending?

This is one of the main issues related to digital currencies. In practice, this is a condition of passing a digital certificate, since the card can be used multiple times through a digital file that is often easily cloned. It only leads to inflation and the organization has to bear huge losses. A major technical goal of blockchain is to eliminate this approach as much as possible.

Explain the importance of blind signatures and how they are useful?

It is actually a form of digital signature, an important part of cryptography, where all information is blinded until it is actually considered or signed. This is a proven method often considered in different privacy-related agreements between the author and the signatory. Digital currency design is one of the most common examples.

What is key sharing? Are there any benefits to blockchain technology?

As we all know, security issues in digital transactions are very important. Key sharing is a similar approach. In blockchain technology, this is a method of dividing keys or personal information into different units and sending them to network users. The original information can only be merged if the participant who distributed the key agrees to be merged with other participants. It can provide various security-related benefits in blockchain technology.

What organizations can use blockchain technology?

This method can be considered as commercial class without strict upper limit. In fact, almost all businesses are doing or online financial transactions that require them to successfully complete the implementation process. Large enterprises, financial institutions, private enterprises, government departments, and even defense agencies can easily trust this technology.

What is the difference between a blockchain ledger and a general ledger?

First of all, the main difference is that blockchain is a digital ledger that can be easily decentralized. This method works outThe likelihood of error is much lower than with a regular ledger. Normal books are written by hand or by hand, blockchain does all the tasks automatically. You just need to configure it the right way and follow all the guidelines.

What is a soft fork?

Blocks in the ledger are included in a way that builds the longest chain, i.e. the chain with the greatest cumulative difficulty. A fork is a situation where there are two candidate blocks competing to form the longest blockchain, and two miners discover a working problem and fail to synchronize with each other within a short period of time. Causes network fragmentation because some nodes get blocks from miner #1 and others get blocks from miner #2. Forks are usually resolved in one block because the probability of this happening again becomes very low as the next block comes out so soon there is a new longest chain that will be considered primary.
