Public blockchains record transactions openly. Addresses are pseudonymous—meaning they aren’t “your name”—but they can become linked to you through patterns, reuse, and off-chain data.

What commonly leaks identity

  • Reuse of the same address across services.
  • Linking addresses to social media profiles.
  • Depositing/withdrawing through a small set of known entities.

Beginner steps

Use separate addresses for different purposes, avoid sharing screenshots of addresses publicly, and understand that ‘privacy tools’ vary—some improve privacy only for specific actions.

Reality check

Privacy is not a switch; it’s a set of habits and trade-offs.
