đ§ What is a Brain Wallet?
The Concept
A brain wallet derives a private key from a passphrase using SHA-256 hash. The idea: memorize a phrase, access your crypto anywhere.
SHA256("password") â Private Key
The Problem
Humans are terrible at randomness. Attackers run dictionaries with billions of passwords, checking the blockchain for each one.
Result: Millions stolen within seconds of deposit.

â ī¸ Never Use Brain Wallets!
This demo shows why brain wallets are fundamentally broken. Even "clever" passphrases get cracked. Always use cryptographically secure random number generators for key generation.
