㈡ How to build a blockchain website

Websites are no longer mysterious and no longer a high-tech job. Ordinary users can also easily build relatively professional websites. Let me briefly introduce to you some procedures and precautions for building a personal website.
1. Domain Name
If you want people to visit your website, a domain name is essential. The domain name should be as short as possible and as easy to remember as possible, such as the .top domain name. Of course, there are not many domain names that are easy to remember and have characteristics. You need to consider this yourself, as long as you feel that there is a certain pattern or it is easy for users to remember. That’s it.
2. Space
To build a website, you must have a space, which is a place to store the website. For individual users, it is recommended to purchase a virtual host. When purchasing a web host, look at its service, speed, response time, etc. Generally, you can choose a service provider with a certain reputation.
Note: Domain name and space are currently good choices for domestic service providers such as Alibaba Cloud, Western Digital, and China Data.
3. Website program
Of course, the website program should be ready-made, because individuals do not need to compile a website program from scratch, and they do not have the ability. Nowadays, there are ready-made website management systems on the Internet. There are many such systems. You can choose based on your own comprehensive trial.
When choosing a website program, its versatility and secondary development must also be taken into consideration. For those that are not very versatile and are not conducive to the second phase of development, although they are powerful, they are not recommended because it will be very troublesome when the website needs to be designed with personalized functions after it reaches a certain scale. in additionTry to choose asp (asp.net) for programs. PHP, JSP, etc. are not particularly popular in China. Try to choose asp.net between asp and asp.net. After all, it is based on the .net architecture and is the development trend.
4. Website Design
After selecting the website program, you need to design the website according to your own needs. Generally speaking, it is best if there are professional artists and programmers to make modifications. However, individual webmasters may not necessarily have this condition and can choose intelligent website building from service providers.

㈢ How to build a blockchain platform

In many cases of blockchain commercial applications, we can always see the word BaaS, which is the abbreviation of Blockchain as a Service. , translated into Chinese as “Blockchain as a Service”. So what exactly is Blockchain as a Service BaaS? With this question in mind, we followed Xiao Wang from the Renren Blockchain Technology Team to discuss it in detail.
According to Xiao Wang: Blockchain as a Service BaaS is a concept mainly proposed by the two giants Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service that combines blockchain technology. . For example, Microsoft's Azure cloud computing platform and IBM's Bluemix Garage cloud platform both provide blockchain as a service BaaS.
Blockchain as a Service (BaaS) is a space created by companies such as Microsoft and IBM from their own cloud service networks to run a certain blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of BaaS nodes is to quickly establish the development environment you need and provide a series of operational services such as blockchain-based search queries, transaction submissions, and data analysis. These services can both It is centralized or decentralized, and is used to help developers verify their concepts and models faster. The serviceability of BaaS nodes is reflected in: stronger tools, making it easier to create, deploy, run and monitor blockchains.

㈣ How to build your own blockchain system

This requires you to have a strong technical team and you must understand the technology yourself
Blockchain technology can be used Go to some specific industries
Which industry do you want to integrate into and what are the specific needs of customers
Develop targeted solutions for several core technologies of the blockchain

㈤ How to build blockchain services

Blockchain services refer to developing public chain applications based on the infrastructure provided by the public chain and running the applications to provide services. For example, smart contracts are used to develop public chain applications on Ethereum and run on Ethereum nodes to provide effective services to the public. On Bitcoin, some certificate deposit services are provided using the limited functions of Bitcoin.
Blockchain developers should establish effective channels that can collect the shortcomings of the current blockchain and make targeted improvements. This process is called Improvement Proposal.s (Improvement Proposal): Bitcoin Segwit (consisting of a series of BIPs) is a good example. Developers at the application layer can use the IP process to feed back problems discovered during use to developers, forming a virtuous cycle. And the IP process should not be limited to the technical field, but should go deep into the Business Layer.

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 the Hyperledger 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 queryContract 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.
Then the contract I uploaded will appear in the Smart Contracts list and can be deployed, called and queried as before.

㈨ What is blockchain and how to make money with blockchain

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

How to make money in the blockchain:

1. Earn commissions through promotion.

The blockchain approach is to first register an exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you will get a commission.

2. Coin speculation.

Speculating in currencies is like speculating in stocks. Coin speculation is the lowest threshold way to make money in the blockchain.

3. Mining.

"Mining" in Bitcoin is the accounting process. This process requires grabbing. If you grab the opportunity to keep the accounting rights, you will be rewarded. The reward is somethingWest is Bitcoin. This behavior is "mining".

4. Develop wallet.

The wallet is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain.

Extended information:

1. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the bottom layer of Bitcoin. technology. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

2. Blockchain was born from Satoshi Nakamoto’s Bitcoin. Since 2009, various Bitcoin-like digital currencies have appeared, all based on public blockchains.

3. On January 20, 2016, the Digital Currency Seminar of the People’s Bank of China announced that it had achieved phased results in digital currency research. The meeting affirmed the value of digital currency in reducing the issuance of traditional currency and stated that the central bank is exploring the issuance of digital currency. The expression of the People’s Bank of China’s Digital Currency Seminar has greatly enhanced the confidence of the digital currency industry. This is the first time that the five central bank ministries and commissions have expressed a clear attitude towards digital currencies since they issued a notice on preventing Bitcoin risks on December 5, 2013.
