One practical way to evaluate a network’s post-quantum posture is to examine whether it publishes a structured inventory of cryptographic surfaces, their current status, and the residual assumptions each still carries. @Starknet maintains such a register covering accounts, proofs, protocol cryptography, existing deployments, and settlement-layer dependencies. Each entry notes what is true today, what remains, and who can change it. This format makes several things observable. First, the proving layer’s reliance on hash functions rather than elliptic curves is structural and already in place. Second, account-level signature upgrades are possible via the validation function, yet ordinary users still use classical signatures because wallet and audit work is incomplete. Third, certain hash replacements have already shipped, while trie and address changes remain on the roadmap. Fourth, full end-to-end independence from the settlement layer’s timeline is not claimed; it is listed as an open dependency. Public inventories of this kind reduce the gap between marketing statements and engineering reality. They also create a baseline against which future progress can be measured. Other networks could adopt similar registers regardless of their specific technical choices; the value lies in the explicit enumeration of assumptions rather than in any single architecture.
