Definition ∞ Blockchain Dependency refers to a system or application’s reliance on a specific blockchain for its fundamental operations or data integrity. This means the system cannot function without the underlying blockchain’s continuous and correct operation. It highlights the critical link between a decentralized application and its foundational ledger technology.
Context ∞ The increasing adoption of decentralized applications brings blockchain dependency into focus, particularly regarding scalability, security, and interoperability. Debates often address the risks associated with single-chain reliance, prompting consideration of multi-chain strategies and modular blockchain designs to mitigate potential points of failure.
