A Cryptocurrency public wallet address is the identifier where a transaction is sent on a specific blockchain. In Ethereum, the users’ address is derived from their public key, then derived from the private key using asymmetric key cryptography. Every cryptocurrency blockchain relies on different cryptographic algorithms. For example, in Ethereum, the public key is 512 bits which are then hashed using the Keccak-256 algorithm, which transforms it into 256 bits. The last 40 hexadecimal characters of this hash are your Ethereum’s public key or public address. Most Ethereum public keys/wallet addresses start with the prefix “0x. To simplify sending and receiving transactions on a blockchain network such as Ethereum, the wallet address / public key is often represented as a QR code that smartphones can easily read.
