Quantum computing is slowly changing the security conversation in crypto. One project taking this challenge seriously is @Starknet, which is exploring ways to make blockchain infrastructure more adaptable to future cryptographic threats. Its STARK-based proof system provides a strong foundation, while local account abstraction creates flexibility for adopting post-quantum signature schemes. The Falcon-512 signed transaction test on mainnet is another step worth paying attention to. But there's more to consider. As an Ethereum L2, Starknet still depends on Ethereum for settlement and data availability, including cryptographic components like KZG commitments. This brings up an interesting question: what would a blockchain look like if its entire security foundation was designed for the post-quantum era? Research into an independent post-quantum L1 is moving forward, with 93.52% support in a non-binding community vote. One figure that stands out is the reported Falcon-512 transaction cost of just $0.023. Quantum-resistant security could become a major part of blockchain's next evolution. Definitely a space worth following. $STRK
