信通院隐私计算报告

Secret vs Oasis vs Phala

• https://foresightnews.pro/article/detail/10818
• 都是 L1 隐私公链，Secret & Oasis 基于 Cosmos SDK 开发，Phala 是 Polkadot 平行链
• 都属于机密计算，基于可信执行环境 TEE
• Oasis 智能合约兼容 EVM，容易学习上手
• Secret 和 Phala 基于 Rust Wasm，学习成本较高

Oasis Network

• Using Go & Rust
• 共识层（consensus layer）和并行运行时（ParaTimes）分离，目前有三种 ParaTimes 实现：

  • Emerald ParaTime: EVM compatible

  • Sapphire ParaTime

    • EVM compatible + TEE
    • Confidential state: private state variables are not visible to all notes.
    • end-to-end encryption: Only the caller and the contract can see the data sent to/received from the ParaTime
    • confidential randomness: generate private entropy

    Guide | Oasis Network Documentation

  • Cipher ParaTime:

    • Rust Wasm smart contracts
    • Flexibility — Developer can define which data to store in a public and which data in the (more expensive) confidential storage
• 似乎未接入 IBC

Secret Network

• Rust Wasm
• IBC connected

Phala Network

• Polkadot 平行链
• Rust Wasm
