Development and construction of NFT mining tour gamefi chain tour system

NFT What is the practical significance of ？NFT It can be simply understood as a blockchain based digital certificate , You can digitize physical or virtual objects , So everything can be NFT, But it's not that simple .

NFT Mining Tour GameFi For the development of chain game system, ask a Peng :132.. Wei 4z77 Heft z558,GameFi Chain game system development and construction , let me put it another way ,NFT The basic logic of is scarcity , Or create an atmosphere of scarcity .

At present, many domestic investors seem to see business opportunities , They have poured into this market to understand and participate in . Development nft Type of software platform , Looking for the right art collector, etc . But for details such as the top chord, the operation is completely different .

One 、 Understand the current basic situation of China's blockchain :

1. Ant chain

Ant chain belongs to ant group , It aims to promote the popularization of blockchain technology . stay 2020 Four years before , The blockchain patent technology applied by ant chain also ranks first in the world .

2.BSN Alliance chain

BSN The alliance chain belongs to the National Information Center 、 China Mobile 、 China UnionPay and jingzao jointly initiated and established the underlying framework . Developers can choose an open alliance chain suitable for application business needs to deploy and run smart contracts and distributed applications .

3. To the letter chain

Zhixin chain is Tencent + The trusted depository block chain service for mutual information released by Beijing fengzhishun Technology Development Co., Ltd .

4. Baidu super chain

Baidu super chain belongs to Baidu . This project is from 2019 year 5 Open source in January , Its application has been applied to medical treatment 、 Government affairs, etc 20 Fields .

about nft Use of type platform , Different chains require technicians to develop different smart contracts as docking , The casting and trading of digital art products require different equivalent fuel costs .

Processes based on different public chains

The process of legalization is as follows ：

Select a public blockchain . The choice here will determine the technology stack of system components such as smart contracts , This is central ;

Develop smart contracts on the selected public chain ;

The developed smart contract needs to follow some basic conventions , For example, it can at least guarantee the material id Can achieve verification and weight removal , What does that mean ？ intend , If A Uploaded today id=1 To the chain , Tomorrow, B Also upload the same id=1 To the chain , The contract should tell B, You can't upload ,id Already exist ;

Deploy smart contracts to the chain , Now it becomes DApp;

By sending a transaction , Call the method of the smart contract , take id And other relevant data are stored on the chain .

NFT Smart contract

NFT Smart contracts can be developed based on different public chains , It is not limited to any common chain . The implementation of smart contract schemes of different public chains is also different , The following is an example of Ethereum public chain .

Above Ethereum , Development NFT Intelligent contract , There are already many standards , such as ERC-7211155998, Each has its own characteristics , But their characteristics are extended from the basic attributes .

If you choose ERC-721 Standard development NFT Intelligent contract , In the metadata storage section , There is tokenUrl the , It is equivalent to the only of matter id, Like the following ,_tokenURIs What is stored is the current count of the pass id It corresponds to tokenUrl, there tokenUrl It's a string format , It's usually a document url, Stored in IPFS Or links to files on other services , But not limited to links , It can also be other content .
