Optimism announced the use of the OP Stack to build L3, which can now join the Superchain. L3 can be built on the OP Stack and share revenue with the Optimism Collective, accessing the network of Superchain builders and qualifying for Retro subsidies, airdrops, and growth activities. Odaily will analyze this change and the story behind it in this article.

Interpretation of Development Plans

Interpretation of Basic Concepts and Announcements

First of all, what is OP Stack? OP Stack is an open standard codebase that supports the development of the Superchain, not limited to L2 chains and DApp developers (well-known cases include Base, Zora Network, etc.), and the L3 ecosystem can also use it.

Another important question, what is the Superchain? The Superchain is a major vision of Optimism, envisioned as a decentralized network of L2 chains (now also including L3), which share security, communication layer, and open-source technology OP Stack. These chains have standardized characteristics, and network resources are interchangeable to enhance the interoperability of the chains, enabling developers to create DApps targeting the entire Superchain.

The latest announcement from Optimism can be understood as allowing developers using the OP Stack to build L3 to join the development map of Optimism's Superchain, enjoying the benefits of the overall ecosystem development. For these L3, direct benefits include Retro subsidies, airdrops, and growth activities, and these joining L3 will feedback some of their income to the Optimism Collective.

However, it should be noted that the OP Stack technology for L3 is not yet fully mature, especially in terms of interoperability.

Application Demand Driving Technological Change?

Why did Optimism make this change? The official announcement outlined a lengthy technical and visionary explanation, but the most important content may be as follows:

L3 can provide a new and more cost-effective way of building for chain and DApp developers. We have seen this trend on Base, which quickly expanded its support for L3 on the existing basis.

It is not difficult to see that this refers to the L3 Degen on the Base chain. The story behind this can be traced back to a story that happened on Warpcast a month ago:

Binji Pande, the head of Optimism NFT, asked in a post on why DEGEN L3 used Arbitrum Orbit technology instead of OP Stack. (Note: Arbitrum Orbit is a chain development tool introduced by the Arbitrum team.)

Syndicate, a collaborating developer of Degen, replied below the article: "The ability to support custom Gas tokens is a big advantage!" (OP Stack does not support custom Gas tokens, so we don't use it.)

Subsequently, Zain Bacchus, the product manager of OP Labs, replied: "Custom Gas tokens will be launched this quarter."

What else is new?

This update includes custom Gas tokens and Plasma mode.

First, OP Stack will support L3 custom Gas tokens, allowing projects in the community built around existing L2 native tokens to use their tokens as Gas tokens to develop their community into an L3 ecosystem. This also reduces the entry cost for new users, as they no longer need to deposit Gas tokens into L2 through expensive L1 operations before entering L3, but can simply execute low-cost L2 deposit operations in L3.

The optional data availability (DA) layer is another key module for developers to build low-cost chains. The Plasma mode allows all developers to choose the DA layer based on the OP Stack to reduce transaction costs while minimizing security issues and management costs. OP Stack will gradually integrate multiple data availability layers.

Looking ahead, this opens up a framework for L3 developers to participate in the Superchain ecosystem, helping to shape a scalable future and benefiting from the contributions of other builders.

Conclusion

In the current era of the proliferation of various chains, whether it's L1, L2, or L3, they are no longer scarce. When there are too many "gold diggers," the most stable and effective way of doing business is to be the one who "sells shovels." From the latest announcement, it can be seen that Optimism is actively adapting to market demand, aiming to make OP Stack the ultimate weapon to achieve the vision of the Superchain.
