Arc is not waiting for the market to force a change when it comes to quantum threats. The team released a detailed post-quantum roadmap that goes far beyond just wallet signatures. It covers the entire stack including quantum-secure private state validator hardening and supporting infrastructure. The goal is to give developers a practical way to build long-lived financial applications today without worrying about a sudden forced migration later. This forward-thinking approach sets a new standard for resilient blockchain infrastructure in a post-quantum world.
