Ⅰ How about investing in blockchain digital currency? Does anyone have any advice?

1. Invest with spare money
Be sure to invest with spare money and never use leverage. (Actually, this is basic common sense for ordinary people to invest). Compared with stocks, funds, etc., digital currency transactions are more frequent and convenient (7*24 hours), so it is easier for people to be impulsive. Moreover, the bull and bear markets of digital currency often come suddenly, which may bring unnecessary trouble to life if you don’t have spare money.
2. Moving bricks
If you feel that "long-term investment" such as digital currency is too slow and want to make quick money, then "moving bricks" may be more suitable for you.
Buying is to use the price difference of the same digital currency between exchanges to buy and sell, and make profits from it. For example, if the price of X coin is 10 yuan on exchange A and 15 yuan on exchange B, and the price of coin Y is 10 yuan on exchange B and 14 yuan on exchange C, then you can buy it on exchange A. For X currency, transfer the currency to Exchange B and sell it; at the same time, buy Y currency on Exchange B, then transfer it to Exchange C and sell it to earn the price difference.
This way of making money does not require a deep understanding of blockchain knowledge. What is required is speed, courage, time, and energy. If you encounter big fluctuations, the profits will be quite generous. For example, a netizen recently purchased EOS from China and then transferred it to an exchange in South Korea to sell it, making a profit of more than 80,000 yuan in one night.
Of course, "moving bricks" also requires you to have a certain amount of capital reserves (usually around tens of thousands of yuan), otherwise the money earned from the price difference alone will not be enough for transaction fees and currency withdrawal fees.
3. Digital currency investment homework
Before investing in a project, you must do enough homework and understand the future development prospects of the project in detail through various channels, including the profit model, valuation space, and project team. Understand it carefully and deeply. It would be terrible to invest money without knowing what the project is about.
Blockchain is an emerging industry. It is currently in a mixed situation. The quality of the personnel is also uneven. Naturally, there are also scammers who use ICO to make money. When we invest, we must be careful and don’t be fooled by a few people. The beautiful PPT has been deceived. You must keep your eyes open and seek verification from various sources. Even if you have a lot of money, don't be fooled.
As for how to identify a scam, you must rely on yourself. What is certain is that those projects that promise high returns must be scams, because any project has the possibility of failure. In fact, as long as you do multiple verifications , it is not difficult to identify a scam.
4. Psychological Warfare of Digital Currency Investment
1. Buy and leave. This is a very important point. After buying, many people will pay attention to the rise and fall of the price. In severe cases, their mood will also follow the price. It changes with the rise and fall of the price, and even the IQ will change with the rise and fall of the price, so there will be a situation of chasing the rise and killing the fall. When the price starts to soar, I regret buying too little, so I add a position, and the price suddenlyAfter a callback, fear appeared in my heart again, and I thought it would be better to throw it away, so my whole person changed accordingly, and my quality of life was seriously affected.
How to prevent the above situation? The answer is to set an expected return or holding time in your mind before investing. This is actually very important. If you decide to hold it for a year, then don’t go no matter how the price changes. Never mind it, think about it a year later. If you think it's okay to increase by five or ten times, then sell it when it reaches your psychological price.
2. Never take advantage of it. The blockchain industry has just emerged and the market is still blank, so there must be many good projects related to it. We must not invest all our funds in one project, even if this project It’s not good to be very good. You must know that any project may not be successful, so you must learn to diversify your investments. Diversified investments also mean diversifying risks. The most important principle in the investment field is to consider risks first and then returns. Risks are always ours. The first factor to consider.
In addition to diversifying funds into different projects, we should also pay attention to the fact that the proportion of funds used for investment must be reasonably allocated. Never use all of it for investment, because once you use too much money for investment , when the price falls, it will definitely affect your life and then your decision-making. Then you are likely to sell your shares during the bear market. If you cannot survive the bear market, you will naturally not be eligible to enjoy the benefits of the bull market. Gained.

II Determination of the Crime of Illegal Fund-raising in the Blockchain

Refer to the provisions of the Criminal Law on the crime of illegal fund-raising. Whoever uses fraudulent methods to illegally raise funds for the purpose of illegal possession, if the amount is relatively large, shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years, and shall also be fined; if the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than seven years or life imprisonment. and shall be subject to fines or confiscation of property. If a unit commits the crime in the preceding paragraph, the unit shall be fined, and the person directly in charge and other directly responsible personnel shall be punished in accordance with the provisions of the preceding paragraph. Legal basis: Article 192 of the "Criminal Law of the People's Republic of China" Whoever uses fraudulent methods to illegally raise funds for the purpose of illegal possession, and the amount is relatively large, shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years, and shall also be fined; if the amount is huge or If there are other serious circumstances, the offender shall be sentenced to fixed-term imprisonment of not less than seven years or life imprisonment, and shall also be fined or have property confiscated. If a unit commits the crime in the preceding paragraph, the unit shall be fined, and the person directly in charge and other directly responsible personnel shall be punished in accordance with the provisions of the preceding paragraph.

Ⅲ Where can I find a more detailed explanation of blockchain applications

Blockchain applications include mathematical currency, payment and settlement, digital bills, proof of rights and interests, and bank credit reporting
Each The specific application is explained as follows:
1. Digital currency
At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can be used as a quasi-super-sovereign currency through the development of hedging financial derivatives.currency, maintaining a relatively stable price. Digital currency has established digital currency transaction credit backed by sovereign currency. The greater the transaction volume and the more frequent transactions, the stronger the digital currency transaction credit foundation. Once the blockchain credit system is implemented globally, digital currency will become a gold-like global payment credit.
2. Payment and settlement
At this stage, settlement and payment of commercial trade transactions all rely on banks. This traditional method of conducting transactions through intermediaries requires the account opening bank, counterparty bank, central bank, and overseas bank. In this process, each institution has its own accounting system, needs to establish an agency relationship with each other, and needs a credit line; each transaction needs to be recorded in its own bank, and must also be cleared and reconciled with the counterparty, resulting in Transactions are slow and costly. Compared with the traditional payment system, blockchain payment is carried out directly by both parties to the transaction without involving intermediaries. Even if part of the network is paralyzed, it will not affect the operation of the entire system. If a universal distributed inter-bank financial transaction protocol is built based on blockchain technology to provide users with cross-border, real-time payment and clearing services in any currency, cross-border payments will become convenient and low-cost.
Take cross-border exchange as an example. If I open an account in a small bank in my country and remit money to another small bank abroad, the transfer process under the traditional SWIFT system requires the following steps: First, I send money to the small bank to which I belong. Banks submit applications; second, small banks submit applications to large banks in the same country that have signed exchange terms; third, large banks wire transfers to overseas cooperative banks; fourth, cooperative banks remit funds to small overseas banks. Currently, the process takes anywhere from 10 minutes to two days, depending on the country. If you use blockchain-based settlement technology and place an order at a market maker while remitting RMB, a trading bank participating in the system in the world will receive the order, and the two parties will shake hands to complete the exchange. The average payment confirmation speed will be in a few seconds. Within seconds.
3. Digital bills
Digital bills are a brand-new bill presentation form developed by combining blockchain technology with bill attributes, regulations, and markets. It is completely consistent with the technical architecture of the existing electronic bill system. different. The core advantages of digital bills are mainly reflected in: First, the disintermediation of the value transfer of bills. In traditional bill transactions, bill intermediaries often use information differences to match. After point-to-point transactions are realized with the help of blockchain, bill intermediaries will lose their intermediary functions and reposition their identities. The second is to effectively prevent bill market risks. Due to the blockchain's non-tamperable timestamps and the fact that it is open to the entire network, once a transaction is made, there will be no default, thus avoiding the problems of "one ticket selling more" for paper tickets and the out-of-sync payment and endorsement of electronic tickets. Third, the system construction and data storage do not require a central server, eliminating the development costs of central applications and access systems, reducing the maintenance and optimization costs of the system under the traditional model, and reducing the risks caused by system centralization. The fourth is to standardize market order and reduce regulatory costs. The non-tamperable timestamp formed by the continuous connection of blockchain data greatly reduces the cost of supervision and is completely transparent.The data management system provides a trustworthy traceability path, and can establish a common constraint code through programming according to regulatory rules in the chain, achieving full coverage and hard control of regulatory policies.
4. Proof of Rights and Interests
Every node participating in the maintenance of the blockchain can obtain a complete data record. Using the characteristics of the blockchain's reliability and collective maintenance, the rights of the owners of rights and interests can be confirmed. For the need to store permanent records, blockchain is an ideal solution and is suitable for scenarios such as land ownership and equity transactions. Among them, proof of equity is the field with the most applications currently. Equity owners can prove their ownership of the equity with their private keys. When the equity is transferred, it is transferred to the next owner through the blockchain system. The property rights are clear and the records are clear. The entire process does not require the involvement of a third party.
During a keynote address at the 2015 European Financial Journalism Awards for Excellence in Trading Technology in London, Nasdaq CEO Bob Greifeld announced that the exchange intends to use blockchain technology to manage its proxy voting system. Proxy voting is an important and time-consuming operation used by a listed exchange. The application of blockchain technology can allow shareholders to vote without having to attend the company's annual meeting. People can vote using their mobile phones, and Always keep voting records. Blockchain technology is regarded as an advanced technology in the field of equity trading that can ensure transparent transactions in a shorter time.
5. Bank Credit Reference
At present, when developing commercial bank credit business, whether it is for enterprises or individuals, the most basic consideration is the financial credit of the borrower itself. Each bank uploads the repayment status of each borrower to the central bank's credit reference center. When inquiries are needed, the bank will download the reference from the central bank's credit reference center with the customer's authorization. There are problems such as incomplete information, inaccurate data, low usage efficiency, and high usage costs. In this field, the advantage of blockchain is that it relies on program algorithms to automatically record massive information and store it on every computer in the blockchain network. The information is transparent, difficult to tamper with, and has low cost of use. Each commercial bank stores and shares the customer's credit status in its own institution in an encrypted form. When applying for a loan, the customer does not have to go to the central bank to apply for a credit check, that is, decentralization. The lending institution can retrieve the corresponding information data from the blockchain. Complete all credit reporting work.
In short, blockchain has become one of the hot spots of innovation in the financial industry. However, as a new technology, blockchain also has considerable risks. The current settlement system based on blockchain technology is very sensitive to regulatory risks. If participants are worried about the uncertainty of regulatory policies, it may cause the payment system to collapse due to instability. In addition, since its operating rights are controlled by developers, the obvious technical disadvantage is that if the operator itself controls more than 51% of the computing power of the entire network, it can achieve double payment, leading to a breakdown of trust. This is also an important issue that needs to be solved during the application process of blockchain technology.

IV What can blockchain be?

Blockchain is informationA term in the technical field, in essence, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained".
As an important concept of Bitcoin, blockchain is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each data block contains Collects a batch of Bitcoin network transaction information to verify the validity of the information (anti-counterfeiting) and generate the next block.
On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Yi Wen Qi Zi".

IV What is Blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem as other ledgers can easilyVerify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

VI Introduction to the principles and applications of blockchain technology

1. Blockchain is a series of data blocks generated by using cryptographic methods. Each data block contains the information within the past ten minutes. The information of all Bitcoin network transactions is used to verify the validity of its information (anti-counterfeiting) and generate the next block. It is the underlying technology of Bitcoin, like a database ledger that records all transaction records.

2. Broad definition: Use encrypted chain structure to verify and store data, use distributed node consensus algorithm to generate and update data, use automated script code (smart contract) to convert and operate data A new decentralized infrastructure and distributed computing paradigm.

3. Narrow definition: A decentralized shared account that combines data blocks into a specific data structure in a chain in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable.

4. Characteristics of blockchain: Decentralization: The verification, accounting, storage, maintenance and transmission of blockchain data are all based on distributed system organizations, using pure mathematical methods rather than central structures. To establish trust relationships between distributed nodes, thereby forming a decentralized and trustworthy distributed system.

5. Time series data: Blockchain uses a chain block structure with timestamps to store data, thereby adding a time dimension to the data and having strong verifiability and traceability.

6. Collective maintenance: The blockchain system uses a specific economic incentive mechanism to ensure that all nodes in the distributed system can participate in the verification process of data blocks, and select specific nodes through a consensus algorithm Add new blocks to the blockchain.

7. Programmable: Blockchain technology provides a flexible script code system to support users in creating advanced smart contracts, currencies or other decentralized applications.

8. Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, and at the same time uses the powerful computing power formed by consensus algorithms such as workload proof of each node of the distributed system. To resist external attacks and ensure that blockchain data cannot be tampered with or forged, it has high security.

9. Blockchain application scenarios: Digital currency: Represented by Bitcoin Damin Coin, it is essentially a digital currency generated by a distributed network system. Its issuance process does not rely on a specific centralized institution. .

Ⅶ What are the classifications of blockchain and what is the structure of the blockchain?

The concept of blockchain has been quite popular recently. It comes from Bitcoin and so on. The implementation of cryptocurrency, but this technology has been gradually used in various fields. So do you know what the classifications of blockchain are? What is the structure of blockchain? Let’s follow us to find out more.
What are the classifications of blockchain?
1. Public Blockchains (PublicBlockChains)
Public Blockchain means: any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate its consensus process. The public blockchain is the earliest blockchain, and it is also the most widely used blockchain at present. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is one and only one corresponding to this currency in the world. Blockchain.
2. Consortium (Industry) Blockchain (ConsortiumBlockChains)
Industry Blockchain: Multiple preselected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly performed by all preselected nodes. Decision (pre-selected nodes participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (essentially still managed accounting, but become distributed accounting, how many slag points are pre-selected, how to decide each block of notesThe account holder becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
3. Private Blockchain (privateBlockChains)
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, and has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions. At present (Dec2015), conservative giants (traditional finance) want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.
4. Sidechain (Sidechain)
Sidechain is a blockchain used to confirm data from other blockchains. Through the two-way peg (TwoWayPeg) mechanism, various assets such as Bitcoin and Ripple coins can be Transfers are realized on different blockchains at a certain exchange rate.
What is the structure of blockchain?
1. Basic network layer: The basic network layer consists of a data layer and a network layer. The data layer includes underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, Data dissemination mechanism and data verification mechanism, etc.
2. Intermediate protocol layer: The intermediate protocol layer consists of a consensus layer, an incentive layer, and a contract layer. The consensus layer mainly includes 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 includes various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain.
3. Extension layer: This layer is similar to a computer driver and is designed to make blockchain products more practical. There are currently two categories. One is various trading markets, which are important channels for exchanging fiat currencies for cryptocurrency. They are simple to implement, get money quickly, and have low costs, but the risks are also high. The second is the expansion implementation in a certain direction. For example, based on the Yishu side chain, it can provide customized services for third-party publishing organizations, forum websites and other content producers.
4. Application service layer: As the most important link in the blockchain industry chain, the application service layer includes various application scenarios and cases of blockchain, including programmable currency, programmable finance, and programmable society.
The above are the blockchain classifications brought to you by the editor? What is the structure of blockchain? all content.

Ⅷ Summary of general concepts of blockchain

Although I am a front-end developer, it cannot stop me from gossiping about various hot topics. Below is a brief summary of some of the conceptual things learned.

1. Blockchain technology was born with Bitcoin, so first understand the concept of Bitcoin

2. What is Bitcoin

(1) , Digital currency based on distributed network

3. Operating principle of bit system

(1) All nodes will save complete ledgers

(2) The ledgers maintain consistency

4. Blockchain accounting principle

> Hash function is widely used in blockchain technology

(1), Hash function hash: any information will be hashed to get a short summary information

( 2). Hash features: simplified information, identification information, hidden information, verification information

(3) Blockchain accounting will hash the bill information of the time node to form a block

(4). The Bitcoin system records accounts every 10 minutes, that is, the time interval between each block is about 10 minutes

(5) When recording the next bill, it will Hash the hash value of the previous block and the current bill information together as the original information

(6). Each block contains the information of the previous block, and these blocks are combined into Blockchain

5. Bitcoin ownership - asymmetric encryption application

The Bitcoin system uses an elliptic curve signature algorithm. The private key of the algorithm is randomly generated by 32 bytes. The public key can be calculated through the private key. The public key undergoes a sequence of hashing algorithms and encoding algorithms to obtain the Bitcoin address. The address can also be understood as a summary of the public key.

(1). Transfer is to transfer Bitcoin from one address to another

(2). The address private key is an asymmetric relationship. The private key passes through a series of (including two hashes), you can get the address, but the private key cannot be obtained from the address

(3) After the transfer is successful, it is broadcast to other nodes, and other nodes forward it to the relevant node after successful verification. Neighboring nodes, the broadcast information contains the original information and signature information

(4) Verification, other nodes verify whether the signature information is generated by the payer using the private key to sign the original transaction information. If It is recorded (then verify that there is sufficient balance)

6. How to mine Bitcoin

(1) Nodes that complete accounting can obtain a certain number of bits given by the system Coin rewards (this reward process is also the issuance process of Bitcoin, so everyone calls bookkeeping mining)

(2) Only one person can successfully bookkeeping within a period of time, so it is necessary to collect Collect the original transaction information, check whether there is a balance and correct signature

(3) In order to improve the difficulty of accounting, only one person can do accounting in about ten minutes, and the hash result needs to beStart with 0, and introduce random number variables when performing hash

(4) As more miners join, the game becomes more and more difficult, the calculation difficulty increases, and the power loss increases. Domestic electricity costs are low, and China’s computing power accounts for more than half of the entire network

(5). Only the fastest decrypted blocks in the network will be added to the ledger, and other nodes will copy to ensure the ledger. uniqueness. If a node cheats and causes the entire network to fail, it will be discarded and never recorded in the general ledger. Therefore all nodes will abide by the common protocol of the Bitcoin system.

[Thinking about which fields blockchain will extend to]:

From the above concepts, it can be concluded that blockchain technology has such security, uniqueness, Decentralization.

In principle, some information leakage can be avoided, allowing the confirming party to confirm your identity without exposing your real user information.

At present, blockchain technology is mainly used in Bitcoin. I think the greater significance in the future should be in areas that require data privacy and security.

[Thinking about the bottlenecks and limitations of the current development of blockchain]:

Since each node participates in the entire ledger recording activity, it will inevitably cause waste and loss of resources. . As well as increasing the computational difficulty of each node, subsequent development and popularization require hardware improvements for each node.

Ⅸ What are the applications of blockchain industry?

Taking the tourism industry as an example, blockchain applications are mainly concentrated in travel, travel community reviews, digital identity management, credit consumption management, Tracking pilots' professional certificates and qualifications, hotel and airline loyalty programs, reservation management, and consumer points management are several application areas. In addition, with the development of blockchain, many related top domain names have been registered, which has had a relatively large impact on the domain name industry. In addition, blockchain also has applications in finance, games, entertainment and other fields.

X What is blockchain and what is its relationship with Bitcoin

Blockchain in English is Blockchain, which is a computer technology for distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. Blockchain is the underlying technology of Bitcoin, which is like a database ledger that records all transaction records. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience. It is a very important concept in the blockchain world. Many models, such as ledger maintenance, currency issuance, timestamp design, network maintenance, competition between nodes, etc., all rely on this central idea.

The first application of blockchain is Bitcoin, which has been recognized by many countries.Bitcoin’s legal status. There is no Bitcoin organization or central bank in the world to issue Bitcoin. The credibility it relies on is the algorithm. It relies on testing the algorithm and an account book and fair mechanism to ensure circulation. It develops a currency that everyone recognizes and trusts. A mechanism, that's how it works.

Nowadays, people’s concept of blockchain is still very general, and its applications are not very wide. However, in the next ten years or even decades, when it comes to blockchain, it will definitely be the most high-end technology that affects people of all ages. Everyone knows!
