A. What are MLM coins and how to identify MLM coins in digital currencies?

With the hype and rapid development of the blockchain concept, it seems that around the editor There are also more and more people getting involved in blockchain projects. As far as I know, there are three friends who have been exposed to some currencies, and they all ended up losing blood. So today I will briefly introduce to you how to distinguish MLM coins from real blockchain digital currencies.

Nowadays, MLM coins are packaged in an increasingly high-end and secretive way. Sometimes it can be said that it is difficult to distinguish between true and false. So I remind everyone once again to be careful of all kinds of MLM coins and air coins.

B. How to identify the real blockchain digital currency

Whether a certain digital currency is a valuable currency, at present, it basically belongs to the "angel wheel" "In terms of the stage, there are three criteria for judgment, 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, based on the different application scenarios of blockchain technology and 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 it supports Super The authority node supervises the nodes and data of the entire network;

b) Performance efficiency: the efficiency of transactions reaching consensus and being confirmed;

c) Resource consumption: the CPU, Network input, output, storage and other computer resources;

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, it has 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 The total amount of digital currency

After considering the expected asset management market value, development cycle and difficultyFinally, consider issuing XT, an ERC20 digital currency based on Ethereum, with a quantity of 2 billion and will never be issued additionally.

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 services optimized for personal trading strategies

C. Blockchain digital currency Exchange platform building solutions

Digital cash exchanges are the focus of competition in the financial field. Having a good digital currency exchange has a great advantage in peer competition. The market for digital cash exchanges is A world-wide market, a global trading business platform. Digital cash exchanges have different data, customization needs, and functions. A good digital cash exchange platform is rich in functions, safe, and powerful, and is among the best in its category. Product differentiation. Blockchain digital asset exchange technology development

The unique interface of digital cash exchanges can provide customers with convenient means of fund transfer, such as fast recharge, currency withdrawal, currency recharge, etc. Also It can support a variety of trading methods, currency transactions, legal currency transactions, over-the-counter transactions, etc.

1. Off-site exchanges: Off-site exchanges are also called OTC trading markets. This is an unfixed place. , there are no fixed rules and regulations, and there are no prescribed trading products. Users can achieve two-way transactions on off-site exchanges, and transactions are very free. Similar to other blockchain applications, off-site exchanges do not have unified trading systems and mechanisms

2. Currency transaction: Currency transaction, as the name suggests, is the exchange between digital currency and digital currency.Easy, using currency as the unit of evaluation to purchase other currencies, and intermediary according to price priority and time priority.

3. French currency trading: French currency trading can be said to be the most direct way. Digital Cash Talk Bench What is the target price? The direct purchase transaction by users with fiat currency is a French currency exchange. The disadvantage of French currency exchange is that the currencies that can be purchased are limited. For encrypted currency types, it is necessary to purchase other types of currencies and exchange them through currency transactions.

Since the digital asset exchange is targeting the global market, its language richness is very important. The digital asset exchange not only supports the development of multiple currencies, but also supports the customized development of multiple functional modules, and also supports the development of languages ​​in various countries.

The functions of the blockchain digital asset exchange will not stop here. With the upgrade of technology in the future, new and better functions will also appear. Similarly, functional requirements also promote technology upgrades.

D. It can increase the price of graphics cards and there is a global power shortage. What exactly is blockchain and why it can change the world

It is very likely that the term blockchain technology that everyone is paying attention to comes from 2017 In 2017, Bitcoin soared to 100,000 yuan per coin, and the stock price of Xunlei Resources, which built Wanke Cloud with blockchain technology, increased 4 times. This shows that other things and all companies can only be exposed to blockchain. Without exception, the word technology became an instant hit. The term digital currency is gradually gaining popularity among the people, and as it happens, there are usually "coin mining" and "digital currency".

Blockchain technology is different. You can buy and sell directly with sellers. As long as everyone follows the principle of paying once and delivering goods, there will be no problem. In this way, the middleman is eliminated, the stock trading time is greatly shortened, and the whole process is efficient and practical. There will even be no payment failure in the Alipay wallet in the early morning of Double Eleven, and the transaction information of the two parties can only be known to each other. The sensitive transaction information between each other will not be known to third parties, thus ensuring the protection of personal information.

E. How is the recent development of blockchain valuable for investment? Are there any project recommendations?

The current development of blockchain is basically between blockchain 1.0 and blockchain 3.0.
Blockchain 1.0 is mainly about realizing digital currency. Many people use it to issue digital assets, which is what we call digital currency
Then, they can earn profits by buying and selling on exchanges. .
There is also Blockchain 3.0. In this stage, Blockchain is regarded as a broad solution, combined with the technical characteristics of Blockchain, and then applied in different fields. Also called "blockchain implementation application"
The investment value is difficult to judge. Because the information of blockchain projects may also be false, what we can do is to improve our knowledge level and rationally judge the authenticity of a blockchain project.
For blockchain projects, you can also find blockchain companies with better strength in the blockchain industry to discuss further cooperation.Enough to discover some blockchain projects.

F. What is digital currency blockchain

1. Blockchain is a ledger that records digital currency transactions
Take Bitcoin as an example. It has no physical form. Instead, it exists in a dedicated ledger. All Bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of Bitcoins owned by each user. If a person owns Bitcoin, it means that transaction records related to him can be found in the ledger.
The ledger mentioned here is a piece of software, which we can download from the official Bitcoin website, and the underlying technology used in this software is the blockchain. To facilitate understanding, we usually say that the blockchain is the ledger.
The reason why blockchain is used as the underlying technology of the ledger is to achieve the decentralization of digital currency. It can be said that the starting point for a series of problems encountered by digital currencies and the solutions provided comes from decentralization.
2. Blockchain is a technology that ensures the safe use of digital currency. Everyone knows that blockchain technology has two major characteristics: encryption and non-tamperability, which can reduce the probability of errors during the use of digital currency. reduced to 0. Since digital currency has higher encryption requirements, it must be supported by blockchain technology. At present, not only many industries in our country are using blockchain technology, but also many foreign countries are actively using blockchain technology. Blockchain technology.
[Extended information]
Blockchain is the underlying technology of digital currency, and Bitcoin is the first successful application of blockchain.. To understand this problem, we must first recognize the facts: not all blockchains require Issuing digital currency, currently our country strongly supports "coinless blockchain". Generally speaking, public blockchain, that is, public chain, needs to issue tokens as "rewards" to motivate users and maintain system operation, while ordinary blockchain , often called a consortium chain, can or cannot be issued. Private blockchains are mostly used for company internal audits and generally do not need to issue coins. The following is a detailed explanation of the differences between the three blockchains:
1. Public block Chain: A blockchain in which anyone in the world can read and send transactions for validity confirmation, and anyone can participate in its consensus process. Bitcoin and Ethereum are typical applications of public blockchains. Public blockchains are a global Distributed blockchain, blockchain data is open, user participation is high, and it is easy to produce network effects, easy to apply and promote. Therefore, this kind of blockchain operation relies heavily on the incentive mechanism, Bitcoin Tokens such as Ethereum and Ethereum are used as "rewards" for incentives, so public chains need to issue tokens to maintain their own development and ecology.
2. Community Blockchain (Alliance Chain): It means that the participation of nodes in the blockchain is selected in advance. There are usually good network connections and other cooperative relationships between nodes. The data on the blockchain can be open It can also be internal. For a sense of partial distribution, we can think of it as "partial decentralization". Each alliance in the chain has its own centralized management. For example, R3CEV of more than 40 banksIt is a typical alliance chain. This kind of chain usually does not require a lot of money, but there are also individual alliance chains that choose to send money to encourage members in the alliance to contribute, so there are no restrictions on the chain.
3. Private blockchain: refers to a node with only a limited scope of participation, such as a specific organization’s own users, strict permission management for data access and use.. Write permissions in a completely private blockchain It is only in the hands of the participants, and the read permission can be opened to the outside world or restricted to any extent. It is currently mainly used for internal audit work of the company. Therefore, the private chain does not need to issue currency, and it does not have the characteristics of decentralization. It is a kind of centralization management mechanism.

G. What is the concept of blockchain? Is blockchain a scam? The most complete explanation of blockchain

What is the concept of blockchain?

On October 25, 2019, the country advocated the development of blockchain. Overnight, the blockchain concept became popular.

However, many people are hearing about blockchain for the first time.

So, what is blockchain?

Let’s take a look at it from an academic perspective:

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. Information, used to verify the validity of its information (anti-counterfeiting) and generate the next block.

In fact, blockchain is essentially a decentralized database.

Is blockchain the same as Bitcoin? Blockchain is not Bitcoin. The first application of blockchain is Bitcoin.

What are the characteristics of blockchain? Now let’s take a look at several characteristics of the blockchain:

1. Decentralization:

The most important feature of the blockchain is decentralization, and the blockchain system is different Based on a centralized database, it is not controlled by any person or entity. Through distributed storage, data is completely copied and distributed on multiple computers, and each node realizes information self-verification, transmission and management.

2. Non-tamperability:

The blockchain system also has the characteristics of non-tamperability. In the blockchain system, each node is the center and no information can be changed, not even the administrator can modify this information. The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. This situation is basically impossible, thus eliminating the possibility of fraud.

3. Publicity:

In a blockchain system, all nodes in the network can easily access information. The foundation of blockchain technology is open source. In addition to private information being encrypted, blockchain data is open to everyone. Anyone can query blockchain data and develop related applications through public interfaces, so the entire system information is highly transparent. .

4. Independence:

Because the blockchain is decentralized, it can facilitate peer-to-peer transactions, so there is no need for a third party whether in transaction or exchange of funds. of approval.

Based on consensus specifications and protocols, 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 any human intervention.

Let’s assume an environment: 6 people live in dormitory 188 of the university

There is a ledger in the dormitory for Xiao Li, who is good at calculation, to keep accounts.

In the beginning, when the dormitory sold paper boxes or bought some public items, Xiao Li would record them in the ledger. If Xiao Li wanted to enrich himself and made false accounts, there would be less money in the account books, but no one would know.

After all, there is already a general ledger room, who would have nothing to do to keep track of the ledgers?

However, one day, because Xiao Li took more, there were obvious errors in the account book. Now, he could no longer hide it, so Xiao Li had to admit his mistake and make up the money.

So, how to solve this problem?

If blockchain is used to solve the problem:

Everyone in the dormitory takes out a ledger, and every time a transaction occurs, everyone records it in their own ledger. , such problems will not arise, because everyone is keeping accounts and can see the transaction records and final results on the ledger.

Xiao Li can’t change, you can’t change, and neither can your lower bunk. No one can change it.

This is because the previous accounting model was a centralized accounting model, and the current accounting model is a decentralized accounting model, where everyone is the center and everyone is the accountant.

If someone wants to change it, it will obviously be ineffective if they only change the data on their own account book, unless they bribe three people.

So, is blockchain a scam?

With the emergence of the great benefits of blockchain, in a short period of time, the prices of blockchain-related assets have soared, and ordinary investors are becoming more and more interested in blockchain. And criminals have also taken aim at this. There are some criminals who put on the gorgeous cloak of “blockchain” and use the blockchain to commit fraud or issue digital currencies without permission, causing many people to think that blockchainChain is a scam.

But in fact, it is not. Blockchain is just a technology. If it can be used well, it will benefit the public and promote the development of the industry.

In particular, the application of blockchain is very wide and can be applied to almost everything of value to human beings.

Medical field: For example, when you go to the hospital for medical treatment, you can directly check the previous medical treatment in your own database, which greatly saves medical resources and saves medical expenses for repeated examinations.

Food traceability: Do you know where the food on your table comes from? Which logistics team is transporting it? This information can be tracked using blockchain. It can provide us with a single source of truth.

Supply chain application: For example, when we buy a product on Moubao, the product leaves the factory, goes to the distributor for logistics turnover, goes to the seller's store warehouse, and then reaches the consumer's hands. During these processes, if something goes wrong, only you will know about it, and others, especially consumers, will not.

Well, that’s all the relevant knowledge about the concept of blockchain is introduced here, I hope it can be helpful to you.

H. Blockchain Digital Currency Investment Guide, How to Invest in Digital Currency

Digital currency investment is a high-risk, high-return product, so you must objectively evaluate it before investing. Whether you can bear the risks, rather than just seeing high returns and ignoring the risks. It is normal for the price of digital currency to fluctuate and it is traded 24/7, so you should treat it with caution.
How to invest in digital currencies?
First of all, correctly understand its risks and determine whether you can bear it. It is best to invest your spare money.
Secondly, there are many types of digital currencies on the market. Newcomers can only configure 1-3 types when entering the market, but not too many. It is recommended to invest the main funds in Bitcoin. Bitcoin is the most stable among all digital currencies, the consensus is also the strongest, and the future growth rate will be great. The risk of buying Bitcoin is much smaller than that of other digital currencies; the remaining small part of the funds can be Configure other currencies.
Again, choose a safe and reliable exchange to register and open an account, and you can start trading. Once you buy it, leave it, hold the currency and wait for it to rise. If it reaches your psychological expectations, you can sell it to make a profit.
