A growing number of Ethereum developers agree that Layer 2 (L2) solutions are needed to improve scalability and transaction speed. However, this can lead to fragmentation when different L2 blockchains operate in isolation from each other. 🌐

Vitalik Buterin, co-founder of Ethereum, spoke out in December in support of the idea of ​​​​installing the “ZK-EVM” update. This can add complexity, but in theory, it has many benefits.

Currently, to solve the fragmentation problem, it is necessary that users and developers can exchange information about crypto assets between L2 quickly and cheaply, without stopping at Ethereum L1.

Despite the challenges, these L2 solutions already represent a step forward to a new era in blockchain technology. They can be used by developers to explore the capabilities and user experience provided by cross-chain communication secured by Ethereum.
