Solana Identity Starts With a Keypair You Generate Yourself, Not an Account

The author, a week into a Solana learning challenge, argues that Web3 identity works differently from typical online accounts. On Solana, a user creates a keypair locally, and the public key serves as their address while the private key proves ownership. The approach is compared to SSH key authentication, since both rely on Ed25519 cryptography. Unlike usernames assigned and controllable by companies, a Solana address cannot be revoked by any platform, but losing the private key means losing access permanently. The author notes that wallets sign transactions on the user's behalf without exposing the private key to apps.
