Been looking into @Starknet quantum readiness roadmap and honestly, this is something more people should be paying attention to. We usually talk about blockchain speed, scalability, and security. But what happens when the cryptography protecting all of this needs to change? Starknet is already working on this and here's what caught my eye. ( 1. ) Some changes are already live Starknet has moved its OS program and configuration hashes from Pedersen to a BLAKE2s 256 based construction. In simple terms, Pedersen relies on elliptic curve cryptography, while BLAKE2s is a hash function that doesn't depend on the same cryptographic assumptions. And the interesting part? this change is already live on mainnet. it's not just a future plan. ( 2. ) There's still more to do Contract storage, state hashing and contract address derivation are still part of the work ahead. Because making one part of a blockchain quantum resistant doesn't automatically make the entire system secure. These are still roadmap items, so there's more work to get done. ( 3. ) Wallets are another interesting part Starknet has native account abstraction, which gives accounts more flexibility in how they validate transactions. This makes it easier to explore different signature schemes instead of relying on just one approach. There's also been a Falcon 512 post quantum account demonstration on Starknet mainnet. Just keep in mind that it's experimental and unaudited. so this doesn't mean every Starknet wallet is quantum safe already. ( 4. ) What about the remaining challenges? Existing contracts will need a practical migration path, and StarkWare is working on the tooling for that. Then there's Ethereum. Starknet still depends on Ethereum for parts of its bridge messaging and data availability, so Ethereum's own post-quantum transition matters here too. Basically there's more to this than just changing a few cryptographic functions. Overall this is worth watching: Starknet isn't treating quantum readiness like some single upgrade that fixes everything. It's looking at the different layers involved, from hashing and wallets to existing contracts and Ethereum dependencies. Some changes are already live, and a post quantum account has been demonstrated. but the full transition is still a work in progress. Quantum threats might not be an immediate problem for most users, but preparing for them early makes sense. Definitely keeping an eye on this one.
