### Ethereum and L2: Symbiosis or separation?

Hello everyone! Today we are going to talk about a topic that has recently sparked heated discussions in the cryptocurrency circle: Is L2 (Layer 2) Ethereum? 🤔

#### Ethereum's dilemma and the rise of L2

Recently, Ethereum's performance seems a bit unsatisfactory. Critics point out that ETH's market performance is not as good as SOL, and attribute this phenomenon to the increase in L2's market share and the loss of users. This has triggered an important debate: Is L2 a part of Ethereum?

#### Symbiotic relationship: L2's deep connection with Ethereum

From the beginning, L2 has been a core part of Ethereum's expansion plan. They are designed as extensions of Ethereum, aiming to enhance its functionality and attract more users. L2 shares many key features with Ethereum, such as relying on ETH as currency, benefiting from Ethereum's security guarantees, and using Ethereum for data storage and settlement.

By providing lower fees and faster transaction times, L2 makes it easier for developers to build a variety of applications. For example, the explosive growth of memecoin on Base and the rise of SocialFi platforms like Farcaster have created new markets for users.

#### Concerns about vampire attacks

However, there are also concerns that L2 may break away from Ethereum and build its own independent ecosystem, no longer relying on Ethereum's security and ETH as gas. This "L2 out of control" concern is not unreasonable. L2 can definitely build an independent ecosystem with its own validators, but it is a complex and resource-intensive task.

#### Recipe for split?

Instead, L2 builders seem to be playing a different game. Their main goals are to scale transactions, attract developers, incentivize them to build applications for different use cases, and let new users join the cryptocurrency world, while Ethereum handles security and decentralization issues.

But this does not mean that L2 development is problem-free. The surge in L2 proves the success of the Rollup-centric roadmap, but it also brings the risk of split. What we need is a unique and important L2, not a bunch of imitators.

#### Future Outlook: Cooperation and Win-win

We need to ensure that L2 seamlessly connects with Ethereum to avoid falling into the trap of splitting.Teams are developing unified chain networks such as Superchain, AggLayer, Elastic Chain, and Orbit Chains, which are promising moves in this direction.

A healthy L2 ecosystem should be one where chains work together, not in isolation. We need bridges, not moats. Collaboration, communication, education, and incentives are key.

#### Summary

There is no simple answer to the question of whether L2 is Ethereum. There is no doubt that L2 enhances the utility of Ethereum and ETH. Ultimately, Ethereum and L2 are in the same boat. Let us build a future together where Ethereum and L2 thrive as a symbiotic whole and drive the crypto ecosystem forward.
