Encrypted Data

Definition ∞ Encrypted data is information transformed into a secure code to prevent unauthorized access. This process uses cryptographic algorithms to convert plaintext into ciphertext, making it unreadable without the correct decryption key. Encryption ensures data confidentiality and integrity during storage and transmission across networks. It serves as a fundamental security mechanism in digital systems, protecting sensitive information from cyber threats.
Context ∞ In the cryptocurrency and blockchain domains, encrypted data is central to securing transactions, protecting user privacy, and maintaining network integrity. While blockchain ledgers are often public, transaction details or identities can be obscured through various encryption methods, such as zero-knowledge proofs. Discussions frequently center on the balance between data transparency for verification and privacy preservation for users. Advances in cryptographic techniques continue to shape the capabilities and security assurances of decentralized applications and digital asset systems.
