在Web2.0中,中心化平臺的商業模式普遍是透過使用者的資料資源獲取流量和利潤。在Web3.0中,也存在對資料的使用和分析需求。I88智慧合約I928系統開發8024


但是考慮到資料安全和個人隱私,需要在使用者的資料和隱私得到保障的前提下,透過隱私計算的方式完成計算任務。安全多方計算是隱私計算的一種解決方案,可以使互不信任的參與方之間保護隱私的情況下實現協同計算

  

  Estimated units of gas needed for a safe but slow transaction(+estimated price and duration)

  

  Estimated units of gas needed for an average transaction(+estimated price and duration)

  

  Estimated units of gas needed for a fast transaction(+estimated price and duration)

  

  Average confirmation time based on gas price

  

  Contracts that are consuming gas-in other words,popular products that are seeing lots of usage on the network

  

  Accounts that are spending gas-in other words,frequent network users
