Vitalik steps up: The 4-year 'anti-quantum' roadmap officially released Is Ethereum ready if quantum computing's 'brute force cracking' arrives faster than expected? Vitalik Buterin responded clearly today: We not only have a plan, but also a roadmap. Four major vulnerabilities locked down: The plan precisely identifies 4 quantum weaknesses in Ethereum's current architecture. Protocol-level defense: Through multiple underlying upgrades, the consensus mechanism and account system will be fully migrated to 'quantum-resistant encryption' algorithms. 4 years of life-and-death speed: This is a race against quantum physicists. While everyone is watching the 15-minute candlestick charts, Vitalik is looking at the survival crisis 10 years down the road. Ethereum's confidence isn't just about TPS; it's about this 'absolutely unbreakable' defense logic.
