The day before yesterday, another DeFi project caused a data leak scandal, with users' wallet addresses and transaction patterns being sold on the dark web. When I saw this news, I started thinking about a very painful question: how do the internal management of data in oracle networks that provide data support actually work?

Today, let's put aside those complex technical concepts and break down in plain language the approach of a leading oracle project regarding privacy handling. You will find that data compliance and privacy protection are becoming key competitive advantages in the next-generation Web3 infrastructure.

First, let's clarify the core point: any handling of your personal data by such projects must be supported by legal grounds. This is not empty talk; specifically, there are six legitimate scenarios—none can be missing.

**First: Your explicit consent**
This is the simplest and most fragile type. Like the checkboxes for "I agree to the terms" when registering—honestly, how many people actually read them? In the Web3 world, this approach is even more covert. The key point here is: your consent must be specific and explicit, informed, and can be withdrawn at any time. If an oracle project wants to collect data, theoretically, they must make it clear to you what they want and what they will do with it.

**Second: Necessary for completing the service**
This is the most common situation. When you call an oracle data service, the project needs to process basic information like your request address and gas fees to complete the service. For example, like ordering takeout—delivery platforms must know your address to deliver. But there's a nuance: only collect necessary data; don't take more than needed.

**Third: Legal obligation**
Regulatory authorities come with legal documents demanding data, and the project must cooperate. This is unavoidable in any jurisdiction.
