Protocol Assumptions and the Application Layer: When Smart Contracts Undermine the Stack Beneath Them
The boundary between application logic and protocol infrastructure is rarely as clean as system architects intend. Smart contract behavior routinely violates assumptions baked into the consensus and execution layers beneath it, producing emergent vulnerabilities and performance pathologies that neither layer was designed to handle alone. This article examines the mechanisms of cross-layer interference and offers concrete guidance for developers building on decentralized networks.
