A wallet address, also known as a public key or public address, is a unique alphanumeric string that serves as a destination for cryptocurrency transactions.
It is used to identify and receive funds in a cryptocurrency network. Each cryptocurrency typically has its own format for wallet addresses.
When someone wants to send cryptocurrency to you, they need to know your wallet address to specify the recipient. Wallet addresses are generated through cryptographic algorithms and are associated with a specific wallet or user.
Here are some key points about wallet addresses:
1. Unique Identifier: A wallet address is a unique identifier associated with a specific cryptocurrency wallet or user. No two wallet addresses are the same across the network.
2. Publicly Visible: Wallet addresses are publicly visible and can be shared with others to receive funds. However, the identity of the owner behind the wallet address is generally not disclosed unless explicitly provided.
3. One-Way Function: Wallet addresses are generated through cryptographic algorithms, typically involving hashing functions, which make it computationally infeasible to derive the private key (used for transaction signing) from the wallet address alone. This ensures that the wallet address can be safely shared without compromising the security of the associated funds.
4. Compatibility: Wallet addresses are specific to the cryptocurrency they are designed for. For example, a Bitcoin wallet address is different from an Ethereum wallet address. It is crucial to use the correct wallet address format when sending or receiving funds to ensure compatibility with the intended cryptocurrency network.
5. QR Codes: Wallet addresses can be represented as QR codes, which are scannable images that simplify the process of sharing addresses. QR codes allow users to easily transmit wallet addresses without the need to manually type in long strings of characters.
It is important to note that wallet addresses are only used for receiving funds. To access and manage the funds associated with a wallet address, the corresponding private key or seed phrase is required.
Private keys are kept secret and are used to sign transactions to authorise the movement of funds from a wallet address.
