Quantum Computing vs. Blockchain: A Sci-Fi-Level Battle

When Vitalik Buterin discusses quantum-resistant upgrades, the topic instantly feels like a scene from a sci-fi movie. Quantum computing is like a future villain, while blockchain is the castle guardian knight.
In reality, current mainstream quantum devices still face technical barriers before cracking large-scale encryption systems. But the consensus in the cryptography community is: migration must happen in advance. Because once quantum capabilities mature, attacks could be instantaneous.
Ethereum’s strategy leans toward gradual upgrades rather than a one-size-fits-all approach. By gradually introducing quantum-safe algorithms through account abstraction and new signature mechanisms, users will have migration options in the future. The technical difficulty is significant, but the feasibility is clear.
From an investment perspective, security upgrades usually don’t immediately reflect in prices, but they do enhance long-term valuation logic. Quantum resistance means increased ecosystem sustainability.
A playful remark: Quantum computing is still leveling up in the lab, while Ethereum has already started upgrading its armor.
