-Generate RSA key pair for signing blockchain blocks:
+To enable Merkle root verification, set `'with_blockchain_root' => true` and generate master keys:
 
 ```bash
-# Generate 2048-bit keys with password
-php artisan blockchain:generate-keys --password=yourpassword

-# Generate 4096-bit keys
-php artisan blockchain:generate-keys --bits=4096
