Re-explain

Private Key:

  • Secret cryptographic key that proves ownership
  • Used to sign transactions
  • Must be kept secure and never shared
  • Losing it means losing access to funds

Public Key:

  • Derived from private key using mathematical functions
  • Can be shared openly
  • Used to generate wallet addresses
  • Allows others to send you cryptocurrency

Analogy: Private key is like your house key (keep it secret), public key is like your home address (share it to receive mail).
