Hello, thank you!

How can enterprises build their own blockchain?

With the popularity of various currency transactions, the development of the exchange industry has been driven. So as a novice who wants to cross industries, how to establish a blockchain exchange development company? Chainsoft Network summarizes the following points for you.

Please click to enter the picture description

1. Determine the operating scope of the exchange development company

Determine the company's The scope of operations is very important, as it determines whether the company has the potential to be profitable. Relevant laws and regulations vary from region to region every day, so the first step is to understand the local laws and regulations, and obtain the necessary licenses and approvals to open a Bitcoin exchange according to your scope of operations, so as to avoid violating local laws and regulations, and bring To cause unnecessary trouble.

2. Check the country’s regulations and compliance requirements

Almost all governments require entities involved in currency exchange businesses to comply with Know Your Customer (KYC) norms. KYC is the process by which businesses verify the identities of their customers through government-issued ID cards or passports. The main purpose here is to prevent money laundering. Make sure to comply with your country’s KYC norms and integrate suitable customer verification procedures in your exchange.

3. Work with a bank or payment processor

You need to work with a bank or payment provider to process payments via fiat currency. You can choose a trustworthy bank with extensive online facilities.

4. Create liquidity on your exchange

Any exchange needs liquidity to operate successfully. Customers are hesitant to place an order or even deposit funds unless they see complete order and trading activity. New trading naturally encounters liquidity issues.

5. Ensure high-level security of trading and customer data

Any exchange development company needs top-notch security to ensure exchange operators and traders’ funds are maintained Safety. This should also apply to your customers’ private data, including their KYC details and bank account information. The Gox breach, a security flaw that went unnoticed for years, resulted in the theft of nearly 1% of all Bitcoins in circulation at the time. According to Chainsoft Network, one-third of all Bitcoin exchanges were hacked between 2009 and 2019. Therefore security must be your top priority in trading.

6. Establish customer support channels

Finally, customer support is another important component of a successful exchange. Staff are needed to approve KYC requests, answer customer complaints, process deposits and withdraw fiat currency, etc. A fast customer support mechanism ensures that your customers start trading from the day they sign up and generate revenue for your exchange.

I hope this helps you solve related problems. For more details, please feel free to consult and discuss!

⑵ How to build a blockchain trading system

First of all, blockchain combines a variety of technologies, including computing, economics, cryptography, etc., combining these disciplines as The foundation of blockchain.

Secondly, combine the blockchain with the corresponding network, and then use mathematical knowledge to establish the relationship between the blockchains. This makes the blockchain a system that can operate independently.

The blockchain transaction system has been transformed from the original single central system control into a flexible social circulation, allowing resources in any field to circulate here and improving work efficiency.

Blockchain digital assets are built on various network platforms. These platforms involve multiple asset fields, including issuers, traders, exchanges, circulation channels and other institutions.

⑶ How to build your own blockchain

Part 1: Establish your own blockchain directory from 0 to 1:
1.1 Start with imitation and get to know the blocks for the first time Chain
1.2 The basis of blockchain: analysis of consensus mechanism
1.3 The design principle and design method of consensus mechanism
1.4 How to quickly clone a blockchain
1.5 How to turn Bitcoin into Become your own private chain – fork Bitcoin
1.6 How to turn Ethereum into your own private chain – fork Ethereum
1.7 How to turn Ripple into your own private chain – fork ripple
1.8 How to turn Stellar into your own private chain – fork Stellar 1.9 How to build a mining pool and mine your own genesis block

1.15 How to use a fund pool to build a currency mixing service
1.16 How to design a new mining algorithm
This process is generally used, but it is also very difficult for ordinary people to complete. Blockchain mature projectsThe projects include Ethereum, DECENT, Bitcoin, etc.

⑷ What technologies are needed to build an NFT platform

If you want to build an NFT platform, you need to master the following technologies: 1 Blockchain technology: To build an NFT platform, you need to master a kind of negotiation Rent blockchain technology in order to create NFT digital assets based on this technology. There are currently a variety of blockchain technologies on the market, such as Ethereum, EOS, TRON, etc. You can choose the appropriate technology based on the specific circumstances of your project.
2Web development skills: Building an NFT platform requires mastering certain web development skills in order to develop the front-end and back-end systems of the project. You need to be proficient in web development languages ​​such as HTML, CSS, and JavaScript.
3 Therefore, my personal suggestion is that it is better to use Xitai NFTsaas directly to build it. This is low-cost, and you only need to do a good job in operations. Technical maintenance and other issues can be solved by the Hanzhao platform.

⑸ How to build the main body of the project for blockchain

When it comes to offshore companies, they usually choose to register in the archipelago. Some domestic giants, such as Alibaba, Tengxu, Shanda Network, Xiaomi, Haidilao, etc., have established overseas IPO structures by registering offshore companies in the archipelago.

Advantages of registering offshore companies in the islands:

1. Complete tax exemption (only a small annual management fee is charged)

2. Company information is kept confidential ( High degree of confidentiality)

3. Overseas IPO structure (domestic giants such as Tencent and Xiaomi have established overseas IPO structures by registering offshore companies)

4. Freedom of naming ( Chinese can be added)

5. No foreign exchange control

6. No specific business scope, as long as it does not engage in illegal and criminal activities or industries that require franchising.

2. The Singapore non-profit foundation can later issue relevant legal opinions to ensure legal compliance and prove that the company's operations are in compliance with Singapore's current laws.

The main contents of the legal opinion:

1. White paper modification: Modify the project white paper where it does not comply with Singapore laws and regulations, and a lawyer will issue a professional legal compliance opinion.

2. TOKEN non-securitization certificate: A lawyer issues a professional legal opinion detailing that the tokens issued by the project do not have the nature of securities.

2.
Quickly create your own blockchain
After registration is completed, return to the homepage and click on the huge GIVE ME A BLOCKCHAIN ​​(Give me a blockchain!) button. Select the Consensus Plugin (consensus plug-in) and Size (number of blockchain network nodes) you want in the pop-up box.
Editor's note: Currently there are two consensus plug-ins officially provided by Hyperledger Fabric: noops and pbft.
After clicking Submit, you will get your own blockchain in a few seconds and automatically enter the monitoring panel. That’s right, getting your own blockchain is that simple!
After entering the monitoring panel, you can see that the left side is the smart contract management panel, including the management and deployment of smart contracts; the right side is the network panel, which displays the applied blockchain network status, topology, and connections between nodes. Latency information, etc. are clear at a glance; click the telescope icon in the upper right corner to monitor the log information of each node in real time. The bottom is the blockchain panel, which shows the overall situation of the current blockchain. In the initial state, there is only one block.
3. Deploy and use smart contracts
Next, the editor will teach you how to deploy and use smart contracts on your own blockchain.
Under the Smart Contracts tab of the smart contract management panel, 2 smart contracts are listed as examples, namely map and chaincode_example02. The map contract can store key-value pairs, and the chaincode_example02 contract can simulate transfers and queries between two people.
Editor's note: The codes for these two sample contracts can be found in HyperleFound in dger Fabric source code.
Take the deployment and use of the chaincode_example02 contract as an example:
Deploy the contract
Click the Deploy button corresponding to the chaincode_example02 contract, and fill in the initialization value of the contract, including the contract name, initial function, and initial parameters. The initial function of the contract is init, and the initial parameters need to be filled in according to the format, such as ["a", "100", "b", "200"], which means registering two people a and b, giving them 100 units and 200 units respectively.
Click the Deploy button and the contract will be deployed in your blockchain. The process will take about 20 to 40 seconds. When a new block appears on the blockchain panel, it usually means that the contract has been deployed.
Call the contract
After the deployment is completed, view the deployed contract instance under the My Deployment tab of the smart contract management panel.
Click the Invoke button below the Action to call the smart contract, and fill in the called method name and corresponding parameters (the method names and parameters of different contracts have different meanings, which are related to the content of the contract). For this contract, call the invoke method name and fill in the parameters ["a", "b", "50"], which means a transfers 50 units to b.
After clicking Submit to complete the call, you can view the blockchain situation and a new block will be generated.


Query Contract
After the call is completed, you can query the contract execution results. Still under the My Deployment tab, click the Query button under Action to query the smart contract, and fill in the query method name and corresponding parameters. If you select the query method name and fill in the parameter ["a"], it means querying the current unit of a.
After clicking Submit, you can see that the current unit of a is 50. You can try query b again!
OK, then you can continue to operate the contract, observe the blockchain situation, or deploy a new smart contract, such as map, on the blockchain. For ease of use, the method names and parameter formats for deploying, calling, and querying contracts are all filled in by default. You only need to select a method name and change the parameters as you like! See how long you can play with the chain~
4. Upload and test your own private smart contract
In addition to the two public smart contracts currently provided, you can also upload and test your own private contract! Private contracts can only be seen by you.
Click Import private smart contract under the Smart Contracts tab.
After filling in the contract name and description, and uploading the contract code file, click Import to complete the upload.
AfterSmart ContraThe contract I uploaded appears in the cts list and can be deployed, called and queried as before.

⑺ Blockchain digital currency exchange platform construction solution

Digital cash exchanges are the focus of competition in the financial field. Having a good digital currency exchange will It has a great advantage in peer competition. The market of digital cash exchanges is a global market, and it is involved in global trading business hosting platforms. Digital cash exchanges have different customization needs and different functions due to different data. The digital cash exchange platform is rich in functions, secure and powerful, and differentiated among similar products. Blockchain digital asset exchange technology development

The unique interface of digital cash exchanges can provide customers with convenient Fund transfer methods, such as fast recharge, currency withdrawal, currency recharge, etc. It can also support multiple transaction methods, currency transactions, legal currency transactions, over-the-counter transactions, etc.

1. Remote exchanges :Off-site exchange is also called OTC trading market. This is a place with no fixed place, no fixed rules and regulations, and no prescribed trading products. Users can achieve two-way transactions on off-site exchanges, and transactions are very free. It is the same as other blockchain applications. The exchange does not have a unified trading system and mechanism

2. Currency trading: Currency trading, as the name suggests, is a transaction between digital currency and digital currency. Currency is used as the evaluation unit to purchase other currencies, based on price. Intermediation is carried out in priority and time priority.

3. French currency trading: French currency trading can be said to be the most direct way. What is the target price of the digital cash platform? 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.

⑻ What role can blockchain technology play in the field of environmental protection?

Now many public welfare organizations have begun to use blockchain technology. In the post-epidemic era, the three pillars of the digital economy are the new online economy. outbreak, smart manufacturing is developing steadily, and the contactless economy is rising. New infrastructure has become a hot topic during the two sessions and a growth point in the future, and blockchain has unique advantages in empowering ecological and environmental protection.

Construct a digital points reward mechanism: The establishment of residents’ environmental awareness is not directly proportional to their actual actions. For example, the importance of environmental protection is generally recognized. In “garbage classification”, it is difficult to classify , difficult processes, difficult management and other "difficulties", with little effect. The use of blockchain technology can establish a points reward system so that everyone involved in environmental protection can create visible "value" and stimulate people's enthusiasm. The point-to-point transmission method of the blockchain not only ensures the security of points, but also avoids corruption and other problems and the consumption of human resources caused by the traditional "top-down" method;

Environmental protection Traceability of the entire management process: In terms of garbage classification and recycling of old items, we have made many years of efforts before, but it has not achieved good results. The reason is that the garbage is classified but the garbage truck is still loaded in one place or the garbage is transported to the treatment plant and is still burned together. , making garbage classification and recycling meaningless. In the blockchain, the information of every item in the garbage classification is fully transparent and traceable, ensuring that our environmental protection work is implemented effectively.

The Xueshuo Innovation Blockchain Technology Workstation under Lianqiao Education Online is the “Smart Learning Workshop 2020- Xueshuo” launched by the School Planning and Construction Development Center of the Ministry of Education of China. "Innovation Workstation" is the only approved "blockchain technology professional" pilot workstation. The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

⑼ What kind of power can blockchain play in environmental protection

As a disruptive emerging technology, blockchain has risen to national strategy and become a new infrastructure of trust in the digital economy era. However, many people still believe that blockchain technology is more used in the financial field, but its technical characteristics of distribution, non-tamperability and collaborative consensus determine that it can be applied in many fields involving data and collaborative work. , especially in the field of environmental protection.

Currently, customers are transmitting hundreds of millions or even billions of distributed energy assets to the power grid. However, energy data flow and transactions are still due to incomplete infrastructure and data asynchronous, It is restricted by problems such as imbalance of supply and demand, complicated transaction clearing process, and unclear ownership of transaction ownership.

State Grid Ningxia Electric Power and State Grid E-commerce Company are actively promoting the integration and innovation of blockchain and new energy business, based on the development of a distributed energy trading platform based on blockchain, with blockchain as the core technology, integrating identity authentication, smart contracts, asymmetric encryption and other technical means, by uploading new energy data to the chain for certificate storage, completing efficient matching of supply and demand data, providing feasible solutions and technical support for new energy consumption, and improving new energy consumption. Comprehensive ability. And further stimulate the enthusiasm of new energy trading entities to participate, attract more load-side resources to flow into the power trading market, optimize energy resource regulation, and realize a green energy economy.
