Does inter‑implementation code reuse pose systemic risks? Yes, inter-implementation code reuse poses a significant and often underestimated systemic risk. If multiple AVS clients use the same open-source library for a critical function—such as BLS signature verification, peer-to-peer networking (e.g., libp2p), or even date-time handling—a bug in that shared library becomes a single point of failure. This creates a hidden correlation where seemingly independent implementations are, in fact, vulnerable to the same trigger. This "supply chain attack" vector can bypass the benefits of client diversity. Mitigating this requires a conscious strategy of dependency diversification, where clients deliberately use different, well-audited libraries for non-core functions to avoid creating a common failure mode.
