Vitalik's perspective shift towards prioritizing "light" Layer 2 solutions while emphasizing "heavy" Layer 1 is fascinating. It indicates a strategic adjustment to scalability and efficiency issues in blockchain technology. Layer 2 solutions can significantly enhance transaction speeds and reduce costs, making them appealing for mainstream adoption. However, the foundation of Layer 1 needs to remain robust to support these innovations. This dual approach could lead to a more sustainable ecosystem, balancing decentralization and usability effectively. I'm curious to see how this will influence future developments in the space. What are your thoughts on the potential impact of this shift?
