Definition ∞ A shared security layer is a blockchain architecture where multiple independent protocols or applications derive their security from a common underlying network, typically a more established and robust blockchain. This allows newer or smaller protocols to bootstrap their security without needing to establish their own extensive validator sets. Participants in the primary network can extend their staked capital to secure these secondary services, often earning additional rewards. This model enhances the overall cryptoeconomic security of the ecosystem.
Context ∞ Shared security layers are a central topic in discussions about blockchain scalability, interoperability, and the efficient allocation of economic security. Debates often concern the potential for systemic risk if a failure in one secured protocol impacts the entire shared layer, or the concentration of power among validators. Future developments will focus on designing more resilient and decentralized shared security models, alongside mechanisms for equitable risk and reward distribution.
