Starknet Weighs Layer 1 Shift to Pursue Quantum Security by 2027

Starknet's consideration of a Layer 1 shift is significant because it would trade the security and composability of Ethereum for unilateral control over upgrade timing — a trade-off that matters most for a chain betting on post-quantum readiness as a differentiator. If quantum security becomes a competitive axis, sovereignty over the upgrade path could be worth the cost of leaving Ethereum's security umbrella. The open question is whether Ethereum's own quantum roadmap makes that trade unnecessary, and whether Starknet's ecosystem would follow a chain that detaches from its settlement layer.
