What is cryptocurrency?
區塊鏈項目 Mina 協議是一種與智能合約兼容的權益證明數字貨幣區塊鏈，旨在為 Web3 構建隱私和安全層。為了實現真正的大規模去中心化，Mina 協議使用了遞歸零知識技術。
主流數字貨幣的儲存需求越來越大，比特幣已經超過了 400G。Mina 協議的創始人預測，像比特幣這樣的貨幣將很快累積到無法記錄所有交易歷史的規模。Mina 協議區塊鏈就是為了解決這個關鍵問題而建立的。它的大小保持不變，約 22 kb，無論使用量的增長。由於它的小，固定的規模，Mina 協議能夠從智能手機和其他區塊鏈快速和直接訪問。
Mina 協議還託管了基於零知識技術的智能合約 zkApps。這允許用戶通過共享證明而不是數據本身來控制他們的數據。
輕量級的驗證器就像 Mina 協議上的節點一樣，持有零知識證明。所有 Mina 協議用戶都可以充當驗證者。Mina 的股權證明機制是 Ouroboros Samasika，是 Cardano 系統的修改，但需要的計算能力要小得多
