Infrastructure Dependency Mapping

Infrastructure Dependency Mapping is the process of identifying the underlying hardware, cloud providers, and software stacks that support a blockchain's validator nodes. Many networks rely on a limited number of cloud service providers, such as AWS or Google Cloud, to host their nodes.

This creates a hidden form of centralization, as a service outage or policy change by these providers could impact a significant portion of the network. Mapping these dependencies helps stakeholders understand the actual level of decentralization and the potential for correlated failures.

If the majority of validators depend on the same infrastructure, the network's resilience is lower than its node count might suggest. This analysis is vital for risk management in the context of smart contract security and protocol uptime.

It exposes the systemic vulnerabilities that exist outside the blockchain code itself. Understanding these dependencies is crucial for building robust, fault-tolerant systems.
