現成MetaForce佛薩奇系統開發原始碼馬蹄鏈

lxqy1668發表於2023-04-12

在效能和隱私安全層面,目前智慧合約受到區塊鏈系統本身效能限制,尚無法處理複雜邏輯和高吞吐量資料,缺乏隱私保護,更無法實現跨鏈,第二層擴充套件解決方案(Layer 2 scaling solution,Layer2)是大幅改善區塊鏈及智慧合約效能的可行辦法,以Taxa區塊鏈為例,它們的基本思路是透過可信硬體為智慧合約創造隔離的鏈下執行環境,公有鏈作為“共識層”記錄最終的通證(Token)支付和合約狀態轉換結果,藉此將智慧合約的執行與公有鏈的共識機制分離,實現部分鏈上操作的鏈外管理,促成高效能、高隱私、可跨鏈的智慧合約。I88智慧合約I928系統開發8024
