Address hash is a unique identifier generated from a public key using cryptographic hashing functions. This process converts the public key into a fixed-length string of characters, making it suitable for use as an address in transactions.When a user wants to send or receive digital assets, they provide their address hash. This hash ensures that the address is both compact and secure, facilitating easier sharing and use in transactions. Because the hashing process is one-way, it’s nearly impossible to reverse-engineer the original public key from the address hash.Different cryptocurrencies may use distinct hashing algorithms, like SHA-256 for Bitcoin or Keccak-256 for Ethereum. Each algorithm adds a layer of security, ensuring that the resulting address hash is unique to the corresponding public key.Overall, address hashes enhance privacy and security for users, allowing them to conduct transactions without exposing their public keys directly.
