Definition
A public key is a cryptographic code used to receive cryptocurrency transactions. It is generated from a private key and can be safely shared with others. Public keys are used to create wallet addresses, allowing users to receive digital assets without exposing sensitive information. In blockchain systems, public and private keys work together to secure ownership and authorize transactions.
Simple Explanation
A public key is like an email address that people use to send cryptocurrency to your wallet.
Example
A Bitcoin user shares their wallet address, derived from their public key, to receive payment from a client.
Why It Matters
Public keys make secure cryptocurrency transactions possible without exposing private credentials.
