Ethereum's long-term security gets a reality check. Vitalik Buterin is pushing the case for quantum-resistant cryptography to be prioritized now rather than kicking it down the road for efficiency reasons. His argument? Simple—the network should lock in 100 years of cryptographic security as fast as possible instead of betting on later optimization windows. It's a stance that balances pragmatism with forward-thinking security posture, reflecting how the space is increasingly serious about quantum threats that may seem distant but demand immediate architectural decisions.
