If you've ever generated an SSH key pair, you already understand Solana identity. ssh-keygen -t ed25519 That command gives you two things: id_ed25519.pub (public key) → put this on servers id_ed25519 (private key) → stays on your machine When you SSH into a server, you prove your identity by signing a challenge with your private key. The server verifies the signature using your public key. Your private key never leaves your machine. Solana works exactly the same way. But instead of one server, the entire network verifies your signature. Instead of just SSH access, your keypair gives you ownership over tokens, programs, and data across every app on Solana. What a Solana address actually is A Solana address is a 32-byte Ed25519 public key, encoded in Base58. Example: 14grJpemFaf88c8tiVb77W7TYg2W3ir6pfkKz3YjhhZ5 Compare that to a Web2 username stored in a database. A company granted you that username. They can revoke it, change it, or lock you out.
