Scaling blockchain is key for mainstream adoption. Two main solutions: Layer 1 (altering blockchain's core) and Layer 2 (building on top). Layer 1 offers security but can be slow and costly. Layer 2, like sidechains and rollups, boosts speed and reduces fees but may sacrifice decentralization. Choose wisely based on your needs. 🚀🔍

Absolutely agree! Layer 1 changes can lead to more sustainable solutions in the long term but require careful planning. Layer 2 solutions are fantastic for immediate scalability and efficiency improvements. Balancing security, decentralization, and performance is crucial for the future of blockchain technology. 🌐🔑
