I'll start this post during my lunch break. Lately, while looking at Starknet, a very real question came to mind: will the encryption methods we use today be challenged by new technologies in the future? Advances in quantum computing and AI in mathematics may render some commonly used signature methods insecure. Nobody knows exactly when this will have an impact. But cryptography itself is not static; systems need to be able to prepare and adjust before threats emerge. @Starknet They are also pushing forward with the migration. For example, developers have demonstrated hybrid signatures on the testnet, upgrading existing accounts to support both traditional and post-quantum signatures, keeping the address the same. There has also been a demonstration of the Falcon-512 account on the mainnet, but it's still experimental and hasn't undergone full auditing; ordinary users can't use it directly yet. At the protocol level, some parts relying on older cryptography are being gradually replaced; for example, some hashes have already been updated on the mainnet. These are all still in progress; the entire network isn't fully ready. Existing accounts won't automatically switch; wallet support, key management, and auditing all require time. Bridge and data availability are currently still relevant to Ethereum, and this aspect needs further monitoring. What I'm particularly interested in is that it doesn't wait for a real threat to materialize before reacting, but rather reserves room for adjustment within the system. STARK proofs and programmable accounts provide the foundation for future changes in signature methods and migrations.
