A. What are the basic characteristics of blockchain

Answer: The basic 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, through distributed accounting and storage, each node realizes self-verification and transmission of information. and management.

2. Openness.

The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data through the public interface. and develop related applications, so 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, and all nodes can automatically and securely operate within the system. Verification and exchange of data do not require any human intervention.

4. Security.

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

5. Anonymity.

Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done anonymously.

B. How to verify the network chain of the Bitcoin wallet

1.
Judge the page after the wallet download and installation is completed from the login method. From this page, you can simply judge Is it a truly decentralized blockchain wallet? Only wallet pages such as imtoken and plus need to create or import a wallet before you can enter the wallet, while other "wallets" only require a username and password to log in! Truly decentralized In a blockchain wallet, once you log out of your wallet account, you must import the wallet, enter the mnemonic phrase, and private key to retrieve it. The developer who develops the wallet cannot help you retrieve it. In other words, it is the wallet's Developers cannot use your assets, this is true decentralization. Many "wallets" on the market do not require a mnemonic or private key after you log out. You only need a username and password to log in. In other words, the assets you deposit into the wallet are centralized and can be accessed by wallet developers at any time. What a terrible black hole it is to transfer your assets, but many people don’t know it
2.
The true decentralized area can be judged by whether the mnemonic words can be imported into each other between multiple wallets. In a blockchain wallet, assets are on the chain and can be transferred between different wallets through mnemonics

C. What is blockchain

May 27, 2021 The Ministry of Industry and Information Technology and the Office of the Central Cyber ​​Security and Information Technology Commission issued the "Guidelines on Accelerating the Application and Industrial Development of Blockchain Technology""Guiding Opinions" (Ministry of Industry and Information Technology Lianxinfa [2021] No. 62), the document defines blockchain as follows:
Blockchain is an important part of the new generation of information technology. It is a distributed network, encryption technology, intelligent New database software that integrates various technologies such as contracts is expected to solve trust and security issues in cyberspace through data transparency, resistance to tampering, and traceability, promote the transformation of the Internet from transmitting information to transmitting value, and reconstruct the information industry system.
Blockchain is the cornerstone of building trust and a trusted network that enables credit transfer and value transfer. Reliable blockchain infrastructure allows enterprises and governments to quickly and efficiently build blockchain networks and industry applications, achieve reliable and rapid flow of capital, logistics, and information flows, and achieve efficient and credible collaboration, helping to reduce collaboration costs and improve Efficiency
The current application of blockchain + industry mainly has the following directions:
Blockchain + insurance industry, insurance companies can optimize business processes and reduce risks through the needs on the blockchain. Customers who purchase insurance have a full, objective and comprehensive understanding of data;
Blockchain + supply chain enables information in all aspects of the supply chain to be updated and shared in real time, making it easier for personnel in each link to understand the latest information and make correct and objective decisions. business judgment.
Blockchain + medical industry, blockchain information cannot be tampered with, ensuring the accuracy and uniqueness of medical data; establishing patient electronic health records, recording real patient health data, and obtaining authorization to view through private keys, that is, protection The collection of sensitive personal data also facilitates doctors to make more accurate treatment plans.

D. What is blockchain and how should it be explained

1. P2P is very popular now, and when it comes to P2P, Bitcoin has to be mentioned. As for Bitcoin, it has an important concept, which is blockchain.

2. What is blockchain? Blockchain is actually equivalent to a disintermediated database, which is composed of a series of data blocks. Each of its data blocks contains information about a Bitcoin network transaction, which is used to verify the validity of the information and generate the next block. In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger. In a broad sense, blockchain is actually a distributed infrastructure and computing method that is used to ensure the security of data transmission and access.

3. The infrastructure of blockchain The blockchain is composed of six infrastructures: data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

4. Purpose of blockchain Blockchain is mainly used to solve trust and security issues in transactions.

E. How to distinguish real and fake blockchain

There is a special group of people who like all kinds of financial investment projects and are looking for them all year roundProjects, especially in the field of blockchain, have created huge wealth miracles and inspired many fund-raising projects under the guise of blockchain, and these investors looking for projects have naturally become various investors. The leek who messes up the project treats the project as a career, but ends up hurting others and himself! The reasons are that one is not enough knowledge, and the other is the wrong mentality. You can't always think about getting rich overnight. A truly good career is built down-to-earth through the accumulation of value over time. If you don't have such a correct mentality, you will be like the above. The people mentioned are always looking for projects to do, but in the end they hurt others and themselves; apart from spending money to buy lessons, the best way to improve cognition is of course learning, and the most efficient way to learn is of course to learn systematic knowledge. The Jiguang Community provides such a professional learning platform to popularize structured and systematic blockchain knowledge for free. Here we will first popularize the anti-fraud knowledge.

First, let’s be clear about one fact. There is no truly mature currency circle in China, and most of them are capital projects disguised as blockchains. Therefore, when making a choice, you must understand and be cautious. The key is to protect your principal!

Second, how to distinguish true from false:

Judging from the entry threshold, there is no entry threshold for real blockchain projects. Anyone can participate, regardless of asset size. And it is free to enter and exit without your principal or custody of funds. The assets will always belong to the users.

From the perspective of income distribution, the real income of the blockchain is earned by users through their contributions rather than the so-called pulling. Human heads can truly produce blood and generate value, rather than a zero-sum game

Third, how to distinguish whether it is truly decentralized:

From the product side, all codes must be Open source on the chain; authoritative audit; all data is on the chain, no user data is stored or infringed.

From the governance side, it is initiated and run by the DAO organization; has its own governance group; has its own Proposal Mechanism

F. How to identify the real blockchain digital currency

Whether a certain digital currency is a valuable currency is basically in the "angel round" stage at present. Generally speaking, there are three judgment criteria, one is the team, the other is the economic model, and the third is industry demand.

The randomness of the team is too great and will not be discussed here. This article first conducts a detailed analysis of the economic model of digital currency. In subsequent articles, the author will analyze some digital currencies according to different industries.

Strictly speaking, the economic model involved in this article is not completely equivalent to the concepts described in economics. Specifically refers to the consensus mechanism and incentive mechanism of currency in digital currency.

1. Consensus Mechanism

The consensus mechanism is the strategy and method for each node in the blockchain system to reach agreement, and should be flexibly selected according to the system type and application scenarios.

Commonly used consensus mechanisms mainly include PoW, PoS, DPoS, PBFT (and their variants), etc. In addition, different applications based on blockchain technologyScenarios, as well as the characteristics of various consensus mechanisms, this article evaluates the technical level of various consensus mechanisms according to the following dimensions:

a) Compliance supervision: whether super authority nodes are supported to supervise the nodes and data of the entire network ;

b) Performance efficiency: the efficiency with which a transaction reaches consensus and is confirmed;

c) Resource consumption: the computer resources such as CPU, network input and output, and storage consumed in the consensus process;< /p>

d) Fault tolerance: the ability to prevent attacks and fraud.

1 Industry background

Find industry pain points: Asset management requires a professional team and knowledge, but most digital currency investors now do not have it; digital The currency market fluctuates greatly, and investors are unable to preserve the value of their assets when the market falls.

2 Own advantages

Having been deeply involved in the stock and futures markets for many years, we have a mature and high-quality asset management team; the AI ​​big data team has strong technical strength.

3 Market Research

After conducting market research, it is estimated that the market value of asset management will be approximately US$1 billion in the next five years.

4 Total amount of digital currency

After considering the expected asset management market value, development cycle and difficulty, consider issuing 2 billion XT digital currency based on Ethereum ERC20, and will never issue additional coins .

5 Distribution method

Early investors hold 10%, the team holds 20%, business operations 10%, community construction 10%, and investors hold 50%.

6 Digital Currency Release/Repurchase Mechanism

The release mechanism is divided into three categories:

Category 1: The currency holding part for business operations is fully unlocked, and the purpose Limited to business and operational activities;

The second category: the release mechanism of the community construction part is that community members release exclusive information, cooperation platforms release exclusive project progress, etc., and based on the number of participating IDs, the corresponding proportion of XT is released (Publishers and participants each receive 50%) until all releases are completed (after the release is completed, subsequent rewards come from the platform profit pool);

The third category: investors hold mainstream digital currencies and are on the platform Asset management is carried out in the platform, and a certain amount of XT is released according to the exchange ratio. Early investors and the team hold part of it in synchronization, and it is unlocked in proportion;

The repurchase mechanism is: 50% of the profit earned (calculated in XT) % will be returned to currency holders; the remainder will enter the platform profit pool, and 50% of the XT in the profit pool will be destroyed on a monthly basis until the total amount of XT reaches 1 billion; the rest will be used as platform ecological construction funds;

7 Digital Currency Rights

Profit Sharing: Holding XT is a platform user and can enjoy 50% of the platform’s profits;

Platform Governance: Participate in platform activities and enjoy XT rewards, Airdrop activities of other project parties;

Function customization: based on platform AI big data, investors can purchase personal trading strategiesOptimized services

G. Illustration of what blockchain is

Blockchain is so popular that it has begun to affect my life. I don’t even want to understand it anymore. Today Let’s take a look at what exactly is blockchain.

Structure of this article:

As its name suggests,
A blockchain is a chain composed of a set of blocks.
A block is a block of information that contains information. , the chain also contains information.

Blockchain technology was first developed by a group of researchers in 1991 to time-stamp digital documents so that these documents cannot be tampered with. It essentially played no other role after that, until 2009, when Satoshi Nakamoto used blockchain technology to create the digital cryptocurrency Bitcoin.

A blockchain is a distributed ledger that is completely open to everyone. It has a very interesting property: once certain data is recorded in a blockchain, the data is very It is difficult to change.

Let’s take a look at the composition of a block:

Each block contains some data, the hash value of this block, and the hash value of the previous block. Hope value.

The data saved in the block is related to the type of blockchain. For example, the blocks in the Bitcoin blockchain save relevant transaction information, including sellers, buyers, and transaction Bitcoins. quantity.

Each block contains a hash value. The hash value is used to identify a block and all the content it contains, and it is unique, like a fingerprint. Once a block is created, its hash value is calculated accordingly. If you change something in the block, the hash value will change. If the fingerprint of a block changes, it will no longer be the previous block.

The third element contained in the block is the hash value of the previous block. This element allows links to be formed between blocks and makes the blockchain very secure.

Suppose we have a blockchain containing 3 blocks
Each block contains its own hash value and the hash value of the previous block
No. 3 Block points to block No. 2, and block No. 2 points to block No. 1
Block No. 1 is a bit special, it cannot point to the previous block because it is the first
We put 1 The block number is called the genesis block.

Now suppose we tamper withThe second block
This will cause the hash value of the second block to change
This will then cause block 3 and all subsequent blocks connected to block 3 to become Illegal
Because the previous block number they stored has now become illegal
So changing one block alone will jointly cause all subsequent contents to become invalid.

But to prevent tampering, hashing is not enough
Because today’s computer computing speed is powerful enough and can calculate thousands of hash values ​​per second
This way You can tamper with a block and recalculate the hashes of other blocks, making your block legal again.

So in order to reduce this risk, the blockchain also uses a technology called proof of work
This is a mechanism that slows down the creation process of new blocks
In the Bitcoin area In the blockchain, it takes about 10 minutes to complete the required proof of work and add a new block to the blockchain
This mechanism makes the tampering of the blockchain more difficult
because once it is tampered with Once a block is obtained, the proof of work of all subsequent blocks needs to be recalculated.

Therefore, the security of blockchain technology mainly comes from hash value and workload proof mechanism.

Blockchain also has a mechanism to protect its own security, which is distributed
Compared to using a centralized entity to manage the blockchain network, blockchain uses A peer-to-peer network that anyone can join
When someone joins this network, he will get a copy of the entire blockchain
This person can use this to verify that all The blocks are still legal and untampered, that is, different nodes can use this to verify each other.

When someone creates a new block,
the new block is sent to everyone on the network.
Everyone then verifies the block to ensure that it has not been tampered with.
If everything is verified correct, then everyone can add the new block to their own area. On the blockchain
We can call it that everyone on the network has reached a "consensus".

All nodes in the blockchain network reach a consensus
They agree on which blocks in the network are legal and which are illegal
Tampered blocks will be rejected by other users on the network
So, to successfully tamper with a blockchain, you need to tamper with all blocks on the blockchain
Re-complete each block Proof of work, and control more than 50% of users in the blockchain network
Only in this way will the blocks you tamper with will be recognized by everyone
It can be said that this is basically impossible to do of!

Blockchain technology itself is also constantly developing
For example, a later technological improvement is called smart contracts
Smart contracts are simple programs stored on the blockchain
br /> It can automatically execute based on the conditions recorded in the contract. As long as the conditions are met, the transaction will be automatically completed in accordance with the contract
For example, automated Bitcoin transactions can be realized under specific conditions.
