Alphanumeric (or alphameric) is a term used to describe any combination of letters and numbers. It can also be referred to as an alphanumeric code or character set. Alphanumeric codes are widely used in the computer world, particularly for passwords and other security measures, but they are also found in everyday life for things like product identification numbers, serial numbers, zip codes, phone numbers and license plate numbers.
In cryptocurrency, alphanumeric strings refer to public keys and private keys associated with each wallet address. These strings are typically long sequences of letters and/or numbers that serve as unique identifiers for transactions within the blockchain network. Public keys are usually displayed publicly on the blockchain while private keys remain hidden from view due to their sensitive nature; only you should ever have access to your private key!
Public keys act like an email address: anyone who knows it can send funds directly into your account without having to ask permission first. Private keys work similarly—they allow you access control over what happens with your funds since they provide cryptographic proof that you own the corresponding public key (and thus the funds associated with it). To protect yourself against theft or loss of funds, it’s important not just to keep these alphanumeric strings secure but also back them up somewhere safe such as a secure offline storage device like a USB drive or paper wallet.
