Secure Ledger

Definition ∞ A secure ledger is a system for recording transactions in a tamper-proof and immutable manner. In blockchain technology, this is achieved through cryptographic principles and distributed consensus mechanisms, where records are linked in a chain and verified by multiple network participants. Once a transaction is added to the ledger, it becomes exceptionally difficult to alter or remove, ensuring data integrity. This design provides a high degree of trust and transparency without requiring a central authority.
Context ∞ The concept of a secure ledger is fundamental to understanding the value proposition of blockchain in crypto news, particularly concerning data integrity and trust minimization. Discussions often compare the security attributes of different blockchain protocols and their resistance to various attack vectors. The continued development of secure ledger technologies remains central to advancing decentralized systems and digital asset security.
