A blockchain shouldn’t become obsolete just because its cryptography does. That’s one reason I’ve been paying attention to @Starknet approach to quantum security. The interesting part isn’t simply using quantum-resistant cryptography. It’s making sure the entire network can evolve without breaking everything built on top of it. Starknet has already taken a concrete step. In July 2026, v0.14.3 replaced Pedersen with a BLAKE2s-256-based construction for OS program and configuration hashes. This change is already live on mainnet. But there’s more to the picture. Native Account Abstraction allows accounts to adopt new signature verification methods without requiring users to abandon their existing account structure. Meanwhile, hash-based STARK proofs avoid the elliptic-curve assumptions threatened by Shor’s algorithm. Still, Starknet isn’t fully quantum-safe today. Pedersen-based storage structures, existing contract compatibility and Ethereum dependencies remain important migration challenges. And that’s what I find most interesting. The real challenge isn’t just finding stronger cryptography. It’s upgrading the foundations while keeping existing applications and users safe. A blockchain built for the future needs more than security against today’s threats. It needs the ability to adapt to tomorrow’s. @Starknet https://t.co/5aRUgftoa5 #Starknet #PostQuantum #STARK
