RSA-260 factored in GPU-accelerated breakthrough, RSA-2048 still holds

• —RSA-260 (862 bits) was factored using GPU-accelerated methods at an estimated cost of $400,000
• —Factoring RSA-1024 is projected to cost around $30 million, while RSA-2048 remains out of reach
• —Bitcoin uses ECDSA rather than RSA, so the network faces no direct threat
• —NIST has finalized post-quantum standards to guide the migration
