    3. 0.6. Why Cryptographic Keys Matter

A cryptographic key is a string of data used in encryption and decryption processes. It secures digital communications and ensures the integrity of transactions on blockchain networks. Cryptographic keys come in pairs: a public key, which is shared and used to encrypt data, and a private key, kept secret by the owner and used to decrypt the data.

Types of Cryptographic Keys

  • Public Key: Used to encrypt data, shared publicly.
  • Private Key: Kept secret, used to decrypt data or sign transactions.

Role of Cryptographic Keys in Blockchain

In blockchain, cryptographic keys are essential for ensuring the security of user wallets, transactions, and contracts. When you send cryptocurrency, your private key signs the transaction, proving ownership and authenticity.

Why Cryptographic Keys Matter

Without cryptographic keys, blockchain networks and digital currencies would not be secure. They provide privacy, prevent fraud, and maintain the integrity of transactions, making them a fundamental aspect of blockchain technology.
