Private Key
Definition
A secret cryptographic key that proves control over crypto assets or wallet actions.
In Plain English
A private key is like the only key to a vault, except there may be no locksmith if you lose it.
Real-World Example
A business holding crypto needs strict private-key custody controls, backups, and approval processes.
Why It Matters for Your Work
Whoever controls the private key can usually move the assets. Lost or stolen keys can be catastrophic.
Common Mistake
Sharing seed phrases or private keys with vendors, support accounts, or screenshots.
