What are private and public keys in cryptocurrency?

In the world of cryptocurrencies, private and public keys play a key role in ensuring the security of transactions. A public key is a kind of address for receiving funds. It is available to everyone and can be used to transfer cryptocurrency to your wallet. In contrast, a private key is a secret code that allows you to sign transactions and confirm ownership of the funds. Only the owner of the private key has access to their cryptocurrency, so it must be stored as securely as possible. Losing a private key may result in the inability to recover access to the funds.
