Top 3 features of Layers 3. From Vince Yang, Co-founder @ zk.Link

🏘 Layer 3 is built on top of Layer 2. It processes and posts transactions, and in some implementations, it can interact directly with Layer 1.

zk.Link Nexus is one of the Layers 3. It uses zk-SNARKs and can integrate with diverse general-purpose zk-rollups.

👮 Layer 3s need to inherit security from Layer 1s and 2s, address challenges in achieving state consistency, and be competitive in terms of performance and cost-effectiveness to gain adoption.

📊 Layer 3s is gonna compete with Layer 2s because they face the same problems: limited developers, limited attention, and limited bandwidth.

Layer 3 has to come with very obvious advantages that solve real problems of developers because Layer 2s in general have a bigger voice and have a bigger ecosystem. Hence, Layer 3s have to be competitive in terms of performance and cost.
