Ethereum co-founder Vitalik Buterin has proposed 'ossification' to secure the blockchain's base layer, aiming for long-term stability. He stressed the importance of upgrading to quantum-resistant cryptography by 2028 and suggested that future innovations should focus on Layer 2 solutions, wallets, and privacy tools. Buterin also underscored the significance of decentralization, contrasting Ethereum's approach with the centralized collapse of FTX.
