Protocol-Native Security

Definition ∞ Protocol-native security refers to the intrinsic safety mechanisms and cryptographic assurances built directly into a blockchain protocol. These features include the consensus algorithm, cryptographic hashing, and transaction validation rules that collectively protect the network from attacks and maintain data integrity. Unlike external security measures, protocol-native security is fundamental to the network’s operation and ensures the immutability and trustworthiness of its ledger. It forms the foundation of a decentralized system’s resilience.
Context ∞ Discussions about the robustness of various blockchain networks in crypto news often center on their protocol-native security. The key debate frequently compares the security properties of different consensus mechanisms, such as Proof of Work versus Proof of Stake, and their susceptibility to various attacks. Developers continuously work to enhance these foundational security layers to resist evolving threats and maintain network stability.
