Base Layer Security

Definition ∞ Base layer security refers to the fundamental defenses built into the core protocol of a blockchain network. This security relies on cryptographic primitives, consensus mechanisms, and network architecture to protect against attacks. It forms the bedrock upon which all higher-level applications and transactions depend.
Context ∞ News often highlights the ongoing efforts to strengthen base layer security in major cryptocurrencies, particularly concerning resilience against 51% attacks and other consensus-level vulnerabilities. A key discussion involves the trade-offs between security, scalability, and decentralization at this foundational level. Future developments will likely include advancements in cryptographic techniques and novel consensus algorithms designed to fortify the base layer against increasingly sophisticated threats.
