A cryptocurrency address is a unique identifier used to send and receive digital assets like Bitcoin or Ethereum. It functions like a digital "address" on the blockchain, ensuring secure transactions through cryptographic keys.

Cryptography is the practice of securing information by converting it into unreadable formats, accessible only with the correct keys. It protects online transactions, personal data, and underpins trust in digital systems like blockchain through encryption and digital signatures.

Staking is locking up your cryptocurrency to support a blockchain, earning rewards in return. It helps secure the network but comes with risks like price volatility, lockup periods, and selecting reliable validators.
