GOODNIGHT CREATORS AND BUILDERS: Starknet and the Quantum-Resistant Future I've been exploring StarkWare's Quantum Hub, and I found two important factors that explain how networks can prepare for quantum resistance: cryptographic agility and migration friction. Here's what I learned. 1. Cryptographic agility matters A blockchain needs the ability to change its cryptographic systems without disrupting the network. StarkWare assessed 10 networks across eight capabilities, including account changes, modular updates, gradual rollouts, tested transitions, and the ability to retire vulnerable cryptography. Within the assessment's scope, @Starknet scored 8/8, Bitcoin, Algorand, and NEAR scored 7/8, while Ethereum scored 3/8. These scores measure evidenced upgrade capabilities, not whether a network is already fully quantum-resistant. 2. Post-quantum migration has four stages → Identify the cryptography that needs replacing. → Introduce and test quantum-resistant alternatives. → Give users a way to migrate their accounts and data. → Retire vulnerable methods and prevent a fallback to weaker security. The challenge is making these changes without compromising users' funds or network operations. 3. Exposure and migration friction tell a different story Exposure considers the status of post-quantum user signing alongside qualifying protections already deployed. Migration friction measures how difficult the transition could be for users, including individual upgrades, coordination, and mandatory cutoffs. According to StarkWare's October 7, 2026 assessment, Starknet, NEAR, and QRL fall into the lower-exposure, lower-friction group. However, their approaches differ. QRL uses XMSS for post-quantum signatures, while NEAR supports opt-in ML-DSA-65 signing on mainnet. Standard Starknet accounts still rely on elliptic-curve signatures. 4. Why paying attention to @Starknet ?? Starknet's STARK proofs rely on hash functions rather than elliptic-curve cryptography, giving its proof system an important structural advantage. Its cryptographic agility assessment also records capabilities designed to support future changes. But there's a crucial distinction: stronger proof security does not automatically make user signatures quantum-resistant. Standard Starknet users still need a supported path to post-quantum signing. Preparing for the quantum era isn't just about choosing stronger cryptography. It's about building a network that can upgrade securely, migrate users efficiently, and retire vulnerable systems before they become a serious problem.
