StarkWare’s Starknet reveals a three-phase, post-quantum security roadmap built on quantum-resistant STARK cryptography to shield Starknet from future quantum attacks.

The architecture relies on STARK proofs and native account abstraction, offering quantum resistance and flexible signature schemes without frequent hard forks for cryptographic upgrades.

Zero-knowledge STARKs are inherently quantum-resistant, and Starknet suggests other chains can reach quantum resistance by selecting suitable cryptographic tools.

The team notes the need to temper overconfidence in elliptic-curve security as quantum threats advance.

CEO Eli Ben-Sasson frames the plan as a proactive move to protect funds in a quantum era, with some threats potentially mitigated within months while full finalization depends on Ethereum’s progress.

Industry context shows other major players like Ethereum Foundation, Ripple, and Quantus pursuing post-quantum roadmaps with targets around 2028–2029, signaling a broader shift toward quantum-resistant cryptography.

Ben-Sasson criticizes industry complacency and urges rapid adoption of quantum-resistant cryptography, noting governance and technical trade-offs but urging action anyway.

He presents the roadmap as a path to safeguarding funds, arguing the needed cryptographic tools already exist and calling out inertia toward migration.

Ben-Sasson warns that resistance to proven quantum-secure cryptography risks ongoing vulnerabilities and rejects rejecting legacy systems as a viable rationale.

Phase two focuses on migration tooling to upgrade existing smart contracts and wallets to the quantum-safe standard without forcing developers to rebuild apps.

This phase develops tools to transition legacy contracts to post-quantum crypto, maintaining compatibility.

Migration tooling aims to help legacy contracts and wallets adopt new cryptographic schemes with minimal disruption.
