Ledger Security

Definition ∞ Ledger security encompasses the measures and protocols implemented to protect a distributed ledger from unauthorized access, alteration, or manipulation. This includes cryptographic techniques, consensus mechanisms, and network architecture designed to ensure the integrity, confidentiality, and availability of transaction data recorded on a blockchain or DLT. It safeguards against various attacks, such as double-spending and data tampering. Robust ledger security is paramount for maintaining confidence in digital asset systems.
Context ∞ Ledger security is a constant priority for all blockchain networks, with continuous research into more resilient consensus algorithms and advanced cryptographic primitives. News often covers security breaches or vulnerabilities discovered in specific protocols, highlighting the persistent need for vigilance and system hardening. The debate also involves the trade-offs between achieving high security levels and other factors like scalability and transaction speed.
