What is the Context of Scalable Security?

In the context of blockchain and digital assets, scalable security is a paramount concern for network upgrades and new protocol designs. News reports frequently assess how proposed solutions for increasing transaction throughput or data storage affect the overall security posture. Maintaining strong cryptographic assurances and attack resistance across a growing, distributed network presents significant technical challenges and ongoing research.

Scalable Security

Definition

Scalable security refers to the ability of a system’s security measures to maintain their effectiveness and robustness as the system grows in size, complexity, or user base. This ensures that protection against attacks does not diminish when the network expands or handles increased data volume. It is a critical design consideration for distributed systems.
