Private Key
A private key is a cryptographic code used to authorize transactions and access cryptocurrency funds in a blockchain wallet. It is the most crucial component of cryptocurrency security, as anyone who possesses the private key can access and control the funds associated with the corresponding public key or wallet address. Private keys must be kept secure and confidential, as losing or exposing them can lead to loss of funds. They are typically represented as long alphanumeric strings or QR codes. Example: A Bitcoin user can only send funds from their wallet if they have access to the private key associated with the wallet's public address.
