Definition ∞ External service risk refers to the potential for vulnerabilities or failures in third-party services that a blockchain project or digital asset platform relies upon. These external dependencies can include oracles, cloud hosting providers, or identity verification services. A compromise or malfunction in such a service can directly impact the security, functionality, or availability of the primary system.
Context ∞ The discussion surrounding external service risk is prominent in news concerning the security and operational resilience of decentralized applications and blockchain platforms. Projects are increasingly evaluated on their ability to mitigate these risks through diversification, robust vetting of third-party providers, and implementation of fail-safe protocols. Understanding this risk is essential for assessing the overall stability of digital asset systems.
