Web3 版本的 HTTPS——机密协议 HTTPZ 要来了。 它使用 FHE 为每个应用默认启用端到端加密。 FHE 应用之所以一直没有普及，就是因为运行速度过慢。 这正是 @Zama 团队过去五年持续攻克的问题。 如今的 FHE 已经足够高效，能够支持任意类型的应用， 并能使用 Solidity、Python 等主流语言开发， 速度比五年前提升了 100 倍以上。 FHE 还具备量子级别的安全性，目前没有任何已知的量子算法可以破解它。 很多人以为 Zama 是新的 L2， 甚至我最开始也这样理解。 但实际上它不是新的 L1 或 L2， 而是 构建在现有区块链之上的跨链保密层。 这意味着用户无需桥接到新链， 即可直接从任意链与保密的去中心化应用（DApp）交互。 Zama 协议能够在现有的公链上，以保密方式发行、管理和交易资产。 本质上，Zama 协议就像 DEX 背后的“语言机”。 你在前端看不到它，但应用的每一步都在依赖它的基础能力。 ---------------------------------------------------------- The Web3 equivalent of HTTPS — the confidential protocol “HTTPZ” — is on the way. It brings default end-to-end encryption to every application through FHE. The reason FHE hasn’t gone mainstream in the past is simple: it used to be far too slow. That’s exactly what the @Zama team has spent the last five years fixing. Today, FHE is finally efficient enough to power real applications. It works with familiar languages like Solidity and Python, and it’s now over 100× faster than it was just a few years ago. On top of that, FHE provides quantum-resistant security, with no known quantum algorithm capable of breaking it. A lot of people still think Zama is launching a new L2 — I actually thought the same at first. But Zama isn’t a new L1 or L2. It’s a cross-chain confidentiality layer built on top of existing blockchains. This means users don’t need to bridge anywhere. They can interact with confidential DApps directly from their current chain. The Zama protocol enables confidential asset issuance, management, and trading across existing public blockchains. At its core, the Zama protocol works like an execution engine behind the scenes — invisible on the front end, but powering everything underneath.
