What Is the Significance of a Bitcoin “Private Key”?

A private key is a secret, cryptographically generated number that proves ownership of a Bitcoin address and authorizes the spending of funds. It is the single most critical piece of information for a Bitcoin user.

Loss of the private key results in permanent loss of funds, while exposure of the key allows anyone to spend the associated coins. It is the foundation of digital ownership in the Bitcoin network.
