Mina 主網升級背景下隱私應用的新面貌

Mina 是零知識支援的區塊鏈，它的不同尋常有幾個原因。它使用 zk SNARK 證明來保持 22 KB 的一致大小

Mina, a blockchain known for its zero knowledge-backed nature, stands out due to several unique characteristics. A key design goal is to maintain a consistent blockchain size of 22 kilobytes through the use of zk SNARK proofs. These proofs are generated off-chain and stored on Mina's mainnet. Notably, Mina serves as the first operational zk rollup, where the blockchain essentially rolls up batches of transactions.

Mina 是一個以其零知識支援性質而聞名的區塊鏈，由於幾個獨特的特徵而脫穎而出。一個關鍵的設計目標是透過使用 zk SNARK 證明來保持一致的 22 KB 區塊鏈大小。這些證明是在鏈外產生並儲存在 Mina 的主網上的。值得注意的是，Mina 是第一個可操作的 zk rollup，區塊鏈本質上是匯總批量交易。

As a constantly evolving 'proof of everything' chain, Mina's off-chain computation involves a combination of sequencing and proof generation. This approach has gained attention from Ethereum layer 2, with the recent Berkeley upgrade adding a layer of programmability to the Mina network.

作為一個不斷發展的「一切證明」鏈，Mina 的鏈外計算涉及排序和證明生成的組合。這種方法引起了以太坊第 2 層的關注，最近伯克利的升級為 Mina 網路添加了一層可編程性。

Decentralization plays a crucial role in the Mina network, often conceptualized as a collection of small rollups. To facilitate application development, frameworks like Protokit are emerging for building essential Ethereum Virtual Machine (EVM) applications.

去中心化在 Mina 網路中起著至關重要的作用，通常被概念化為小型匯總的集合。為了促進應用程式開發，Protokit 等框架不斷湧現，用於建立基本的以太坊虛擬機器 (EVM) 應用程式。

While privacy for user transactions is inherent in all zk rollups, the recent rollups highlight the scalability benefits of zktech. A critical aspect of privacy is that proof generation occurs on the user's device, whether a phone or computer. However, Mina's approach to distributed computation extends functionalities across multiple machines.

雖然用戶交易的隱私是所有 zk rollups 所固有的，但最近的 rollups 凸顯了 zktech 的可擴展性優勢。隱私的一個重要方面是證據生成發生在使用者的裝置上，無論是手機還是電腦。然而，Mina 的分散式計算方法將功能擴展到多台機器上。

Beyond privacy, Mina's architecture enables handling large volumes of data, as the raw data is kept off-chain. This capability becomes particularly relevant for higher application layers that often face challenges in maintaining privacy.

除了隱私之外，Mina 的架構還可以處理大量數據，因為原始數據保持在鏈外。此功能對於經常面臨維護隱私挑戰的較高應用程式層尤其重要。
