Yesterday, a friend who develops data analysis tools spoke anxiously: "Regulators have summoned us, asking how we handle user address associations and IP data... Privacy policies need to be completely rewritten." He sighed: "I thought the blockchain world was free enough, but I didn't expect real-world laws to knock on the door at any time."

This conversation hits many people's blind spots. We enthusiastically embrace the narrative of decentralization and anti-censorship, but often overlook a harsh reality — the teams building the infrastructure are themselves living within a web woven by data protection laws and privacy regulations.

Imagine: a data aggregation platform, a tracking platform, an analysis tool — when they handle user addresses, behavioral data, community information, they are actually dealing with "personal data." This is not an exemption zone for Web3. It means they must, like any traditional tech company, comply with global privacy frameworks such as GDPR.

There is no gray area here. The role of "controller" automatically brings legal responsibilities — deciding how data is processed, how long it is stored, and cross-border transfer rules. From the perspective of data subjects, you have the right to know who is using your information, how they are using it, and how long it is stored.

A project claiming to be "trustworthy" and "transparent" is ultimately judged not by its code, but by how it handles real-world data obligations. This is precisely the key to determining whether a Web3 team is truly long-term oriented.
