Jogger慢跑者流動性挖礦系統(tǒng)的設(shè)計思路是基于去中心化交易平臺的搭建，采用智能合約實現(xiàn)交易撮合和流動性挖礦機制。Traders can provide liquidity in the system and receive rewards from Jogger Jogger Governance Token(BAL),as well as liquidity mining rewards from other traders.The system incentivizes liquidity providers to provide liquidity by sharing transaction fees between liquidity providers and traders.

　　Jogger慢跑者流動性挖礦系統(tǒng)采用以太坊區(qū)塊鏈技術(shù)實現(xiàn)，使用智能合約實現(xiàn)交易撮合和流動性挖礦機制。Smart contracts are the core of the system,responsible for processing traders'transaction requests and liquidity provided by liquidity providers.The system also needs to implement user interfaces and API interfaces,so that traders can trade through web browsers or mobile applications
