Ethereum's cryptographic security is entering a critical discussion phase. There's a growing perspective that implementing quantum-resistant cryptography shouldn't be postponed for efficiency optimization—it's worth doing sooner rather than later. The argument centers on Ethereum's ability to establish and maintain a 100-year cryptographic security guarantee from this point forward. This shift reflects broader industry thinking about blockchain resilience: rather than treating quantum-resistant protocols as a future consideration, they're increasingly viewed as a foundational priority that strengthens the entire ecosystem's longevity and trustworthiness. For Ethereum specifically, this approach would position the network as setting new standards for long-term security architecture in Web3.
