Ethereum co-founder Vitalik Buterin has called for the gradual ossification of Ethereum's main layer to enhance stability and security. Speaking at the Devconnect conference, Buterin emphasized that future innovations should focus on Layer 2 solutions, wallets, and privacy tools rather than the core protocol layer. He also warned that elliptic curve cryptography might be compromised by quantum computing by the 2028 U.S. elections, urging Ethereum to complete its quantum-resistant upgrades within four years.
