Crypto Glossary: Address

Address: In the realm of cryptocurrencies, an address refers to a unique set of alphanumeric characters representing a wallet used for sending and receiving digital assets. It serves as a location identifier within the blockchain network. Cryptocurrency addresses are designed for single-use, typically generated for each transaction.

Key Characteristics:

  • Composition: A cryptocurrency address, such as a Bitcoin address, is typically composed of 26-35 characters, consisting of numbers and letters. Bitcoin addresses often start with the numbers 1, 3, or bc1.
  • Usage: Each address is intended for a specific transaction, allowing users to send or receive cryptocurrencies. Once a transaction is completed, a new address is generated for subsequent use. Unlike a crypto wallet, an address does not maintain a balance.

Public Nature:

  • Blockchain Explorer: Most blockchain addresses are public, enabling users to view transaction history and asset balances through a blockchain explorer. This transparency is applicable to public blockchains like Bitcoin and Ethereum.
  • Privacy Considerations: While addresses are visible on public blockchains, many remain anonymous or pseudonymous. This lack of direct association with real names enhances user privacy. Privacy-focused blockchains like Monero and Grin, however, operate differently.

Ownership and Identification:

  • Anonymous or Pseudonymous Ownership: Cryptocurrency addresses are often associated with anonymous or pseudonymous ownership. This characteristic makes it challenging to identify the individuals behind the addresses, as real names are typically not linked to them.
  • Exceptions: Certain addresses, particularly those owned by exchanges, token project owners, or founders, may be exceptions. In these cases, the owner’s identity is known.


  • Wallet Integration: Cryptographic keys, including the private key corresponding to an address, are integral to the functionality of addresses. Wallet software applications, installed on a user’s device, store these keys, allowing control over the associated cryptocurrency funds.
