An address on a blockchain network functions as a digital location for sending and receiving transactions, as well as identifying individual users, akin to an email address in online communications. It is often referred to as a ‘public key’. Composed of a complex string of alphanumeric characters, an address can also be transformed into a QR code format for convenient scanning purposes.
Specifically within the Ethereum blockchain, addresses start with the prefix ‘0x’. Take, for instance, the following example of an Ethereum address:
0x123456789AbCdEfGhIjKlMnOpQrStUvWxYz012345. This unique identifier ensures that digital assets are accurately attributed and securely managed across the network.
