data KeyPair

KeyPairs are used to store and sign transactions. The PublicKey piece is used as the public address on the blockchain where funds can be sent to and from. The PrivateKey is used to sign transactions, which provides a guarantee that the transaction was initiated by the owner of the address.

Constructors

KeyPair

Fields

• publicKey :: PublicKey
• privateKey :: PrivateKey

generate :: IO KeyPair

Generates a new KeyPair. The PublicKey can be shared openly, while the PrivateKey should be kept secret.
