The Stellar Development Foundation has introduced the 'Quantum Preparedness Plan,' which is designed to strengthen the Stellar network against future quantum threats. The document addresses potential risks associated with quantum computing, as well as the advantages of the Stellar architecture, which could facilitate the transition to quantum-safe cryptography.

The plan includes a three-phase approach to ensuring quantum security. However, since the information is based solely on metadata, details regarding each phase remain unclear. Nevertheless, this indicates that Stellar is actively working on preparations for potential quantum threats.
