How to make the development of liquidity pledge mining system, case analysis and source code of DAPP defi NFT LP liquidity pledge mining system development

　　 Blockchain is a block chain data structure , Based on the time sequence , The blocks storing data are combined in the form of sequential connection , At the same time, it ensures that the data cannot be tampered with and forged by means of cryptography , It is a highly secure distributed ledger . Broadly speaking , Blockchain uses block chain data structure to verify and store data 、 Use the distributed node consensus algorithm to update the data 、 Using cryptography to ensure the security of data transmission and access 、 Use smart contracts written in automated scripts to program and manipulate data , It is a new distributed architecture foundation and computing method .

　　DeFi, Its full name is Decentralized Finance, namely “ Decentralized Finance ” perhaps “ Distributed finance ”.“ Decentralized Finance ”, Compared with traditional centralized finance , It refers to the application of various financial fields established in an open decentralized network , The goal is to build a multidimensional financial system , Based on blockchain technology and cryptocurrency , Recreate and improve the existing financial system .

　　 at present ,DeFi The liquidity of mining , It mainly occurs on Ethereum's blockchain . It is through Ethereum DeFi The product is obtained by providing liquidity . In short , Deposit some token assets to mine , It's called mining , Liquidity mining refers to attracting more capital to participate in project transactions , By issuing their own tokens , Encourage people to provide liquidity in their capital trading pools . A similar , Some new shopping centers encourage customers and sellers to trade in their own shopping centers , They will be given special coupons for shopping malls ( Or equity certificate ). The main purpose of mobile mining is to obtain users and traffic , Allocate your tokens effectively , So that the project has a broader community base .

　　 What is adding liquidity ？ What is the meaning of it ？

　　 Adding liquidity means without causing sharp changes in market asset prices , Add the ability to buy and sell assets in the market . A liquidity pool is a trading pair , So adding liquidity is to recharge the transaction pair , such as ETH/DAI Liquidity pool , You need to recharge at the same time according to a certain proportion ETH and DAI.

　　 Liquidity pools are many decentralized trading platforms (DEX) The backbone of , for example Uniswap. be called “ Liquidity providers (LP)” Of users add two equivalent tokens to the capital pool to create a market . In return , The transaction costs generated in the capital pool will be distributed to users according to their respective proportion in the total working capital . The liquidity pool is a batch of funds deposited into smart contracts by liquidity providers . The user is in AMM When executing a transaction , There is no traditional counterparty , Instead, the liquidity of the liquidity pool . The buyer does not need to deal with the seller when buying , If the liquidity in the pool is sufficient, the transaction can be concluded . For example, in Uniswap When buying the latest food tokens , There is no traditional counterparty ( I.e. the seller ), Instead, there is an algorithm for managing fund pool activities . in addition , The transaction price is determined by this algorithm according to the transactions in the pool .

　　Web3.0 It refers to the decentralized online ecosystem based on blockchain , It is a relatively decentralized , As a user's personal digital identity 、 Digital assets and data completely return to the automation of individuals 、 A new intelligent Internet world . Every interaction between us should be recorded and quantified , We should control our own data ownership and use rights and participate in the resulting benefit distribution fairly . This needs to include blockchain 、 Joint exploration of multiple technologies including artificial intelligence and the Internet of things . The trend we are about to witness is , The Internet will develop with the needs and use of users , Ultimately, it belongs to the user .
