starknet can already change account signatures without a network-wide upgrade. programmable accounts let developers introduce new signature methods while the stark proof system stays the same. that flexibility covers part of the problem. the rest still sits on ethereum’s timeline because starknet is an l2. core security upgrades that touch the wider architecture have to wait for ethereum to move. that is the practical reason they are exploring an independent l1. more control over when and how the chain upgrades its own cryptography as threats change. starknet is preparing for quantum and other future risks. it is not claiming to be fully quantum-safe today. the l1 discussion is about who decides the upgrade schedule, not about being finished. quantum hub: https://t.co/SyfuPCMPxj @Starknet
