Public-Key Cryptography

Cryptography is useful for safeguarding blockchain wallets.

Wallets are used to store digital assets, including cryptocurrencies, non-fungible tokens (NFTs), or any other items created and transferred on the blockchain.

When users create a wallet, they get a public key and a private key. The private key is to your wallet what a password is to your bank account. Every transaction must be signed with a private key to prove ownership of the assets.

The existence of a private key means that no one can gain access to your wallet and move funds and other assets without your approval.
