StarkWare published its post-quantum roadmap for Starknet on June 30, titled “The Architecture Advantage: Starknet’s Post-Quantum Roadmap.”

The goal is an end-to-end post-quantum secure Starknet before Q-day, the point at which a quantum computer could break the cryptography that secures most of crypto today.

StarkWare is treating quantum risk as an engineering project with phases and deadlines, not a vague warning for someone else to handle later.

1/ Starknet is a bet on post-quantum security. Today, we’re publishing the roadmap to make that bet real.

The pitch starts with architecture. StarkWare argues that Starknet’s reliance on STARK
