Mina 主网升级背景下隐私应用的新面貌

Mina 是零知识支持的区块链，它的不同寻常有几个原因。它使用 zk SNARK 证明来保持 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 是一个以其零知识支持性质而闻名的区块链，由于几个独特的特征而脱颖而出。一个关键的设计目标是通过使用 zk SNARK 证明来保持一致的 22 KB 区块链大小。这些证明是在链外生成并存储在 Mina 的主网上的。值得注意的是，Mina 是第一个可操作的 zk rollup，区块链本质上是汇总批量交易。

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.

作为一个不断发展的“一切证明”链，Mina 的链外计算涉及排序和证明生成的组合。这种方法引起了以太坊第 2 层的关注，最近伯克利的升级为 Mina 网络添加了一层可编程性。

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 网络中起着至关重要的作用，通常被概念化为小型汇总的集合。为了促进应用程序开发，Protokit 等框架不断涌现，用于构建基本的以太坊虚拟机 (EVM) 应用程序。

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.

虽然用户交易的隐私是所有 zk rollups 所固有的，但最近的 rollups 凸显了 zktech 的可扩展性优势。隐私的一个重要方面是证据生成发生在用户的设备上，无论是手机还是计算机。然而，Mina 的分布式计算方法将功能扩展到多台机器上。

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.

除了隐私之外，Mina 的架构还可以处理大量数据，因为原始数据保持在链外。此功能对于经常面临维护隐私挑战的较高应用程序层尤其重要。
