# 1.4 Why Liquidity-First Is the Optimal Path

The convergence of validated demand and supply-side failure creates a structurally underserved market position. Demand is reinforced by regulatory mandates (CISA, NIST, NIS2, DORA, FSB). Supply, however, remains structurally broken: centralized vendors lack on-chain verifiability, while existing DePIN models lack effective liquidity formation mechanisms.

For capital allocators, the question is not whether PQC infrastructure is necessary—regulatory mandates have already established that. The critical question is whether a delivery mechanism exists that can attract sufficient liquidity before the threat horizon materializes.
