Public Key

Public Key is a crucial component in cryptographic systems, especially within blockchain technology. It is a long, alphanumeric code derived from a private key through a one-way mathematical function. This key allows users to receive cryptocurrencies securely, acting like an address or account number. While anyone can see and use your public key to send you funds, it does not reveal your private key, maintaining transaction security. Public keys are essential in verifying digital signatures and ensuring data integrity. They enable trustless transactions, where users can interact without needing to know or trust each other.
