 ### Mainnet Frequently Asked Questions
 
+#### Self Staking Risk
+
+Self Staking only has `Read` permissions for Bitcoin, without `Transfer`, ensuring the ownership of BTC. Having `Write` permission at the Rooch layer provides scalability.
+
+Therefore, Self Staking in Grwo Bitcoin is risk-free staking mining.
+
+For example, I want to go shopping in a newly opened supermarket and I want to apply for a membership card. The membership card will only read my identity information and cannot do any more operations. Grow Bitcoin's stake mining is this model. It can only read the UTXO of the Bitcoin wallet and has no authority to operate your Bitcoin assets.

 ### 主网常见问题
 
+#### Self Staking 风险
+
+Self Staking 对 Bitcoin 来说只有 `Read` 权限，没有 `Transfer`，保证了 BTC 的所有权。在 Rooch 层具有 `Write` 权限，提供了扩展性。
+
+因此 Grwo Bitcoin 中的 Self Staking 是零风险的质押挖矿。
+
+举个例子，我要去一个新开的超市买东西，我想办一张会员卡，会员卡只会读取我的身份信息，无法再做更多的操作。Grow Bitcoin 的质押挖矿就是这种模式，只能读取 Bitcoin 钱包的 UTXO，没有权限去操作您的 Bitcoin 资产。
+
+#### 为什么要创建 Session Key
+
+Rooch 的 Session Key 为应用交互提供了安全、简化 DApp 交易流程。

+Session Key 的详细描述请参考这篇文档 https://rooch.network/zh-CN/learn/core-concepts/accounts/session-key
