Many people use blockchain wallets, and their primary concerns are typically transaction speed, fee levels, and DeFi yields. But I believe there’s another issue that’s often overlooked: what happens to our on-chain assets if existing cryptographic algorithms become insecure in the future? This isn’t a distant concern we can safely ignore. As quantum computing advances, traditional signature algorithms may face new security challenges. For ordinary users, the biggest worry isn’t how the technology changes—it’s whether their wallets, addresses, and assets will be affected. I think @Starknet’s approach in this area is well worth examining. Starknet uses the STARK proof system, whose underlying design is based on hash-based cryptography, giving it certain advantages in post-quantum security. More importantly, it employs account abstraction, allowing the logic for account verification to be flexibly updated. In other words, if a new signature algorithm becomes necessary in the future, users may have the opportunity to upgrade their account verification methods to meet new security standards—without having to abandon their original wallet addresses. This may seem minor, but its practical significance is substantial. After all, a wallet might be used for years, holding not only assets but also numerous DeFi approvals and application histories. If every security upgrade required users to create new wallets and migrate assets, the operational costs and potential risks would be extremely high. Starknet’s recent optimization of Falcon-512 verification efficiency is also noteworthy: verification costs have dropped from 48.4 million gas to 24.1 million gas in testing. This shows the team isn’t just researching security—they’re also considering the real-world cost implications of deploying post-quantum solutions. Of course, there’s still a long way to go before the entire ecosystem achieves full quantum resistance; having a superior underlying design doesn’t mean all risks have been eliminated. What I value most is whether Starknet has proactively built in upgrade pathways for the future. After all, true blockchain security isn’t just about remaining unbroken today—it’s about ensuring users can continue to safely and cost-effectively access their assets even as technology evolves.
