A private key is needed to create digital signatures, encrypt or decrypt data. There always exist a cryptographically linked public key to a private key. For blockchain applications, e.g., sproof, the private key is your secret to add or update your data. If you lose your private key, you do not have access anymore. The private key can be encrpyted with a passphrase.
