Scalability vs Customizability: How Slush and Sovereign Extend L1s in Their Own Ways
Sovereign Labs and Slush are both building Rollup ecosystems, but they differ in interoperability, customizability, and scalability.

In this episode of the podcast, Mike and Myles are joined by Kalman Lajko and Preston Evans to discuss the similarities and key differences between Slush and Sovereign design. Both Sovereign Labs and Slush are building Rollup ecosystems, but they differ in terms of interoperability, customizability, and scalability. Highlights from the discussion also touch on topics such as monetization strategies, asset bridging, and infrastructure development for user onboarding.
The Internet of Rollups
-
Preston from Sovereign Labs and Kalman from Slush SDK discussed their vision for an internet of Rollups. In general, rollup blockchains outsource part of their security to another chain, and an internet of rollups could significantly accelerate innovation at the Layer 1 level.
-
They are developing the Sovereign SDK—a toolkit inspired by the Cosmos SDK but specifically designed for application-specific rollups.
-
They utilize zero-knowledge proofs to enable minimal-trust interactions between rollups.
-
Their ultimate goal is to create a rollup ecosystem where rollups can seamlessly communicate with each other.
Slush vs Sovereign
-
Rollups are Layer 2 scaling solutions that increase transactions per second and reduce blockchain fees. There are different types of rollups, including smart contract rollups, Layer 3s built atop settlement rollups, and Sovereign Rollups.
-
The Sovereign Labs team takes a first-principles approach to building rollups, while the Slush team focuses on interoperability and building on mature platforms.
-
Ease of use and interoperability depend heavily on using the same virtual machine and cryptographic primitives.
-
Building on StarkNet has different requirements compared to the design principles in the Cosmos SDK. The Ethereum ecosystem places greater emphasis on security, decentralization, cheap data availability, and fast bridging.
-
The Slush and Cosmos SDK stacks differ in flexibility and are designed to support virtual machines.
-
Bridging between different virtual machines carries risks, so they're focusing on how to secure VMs and enforce their own rules. Smart contracts capable of interpreting the state of other chains are needed, ensuring malicious chains don't affect connected ones.
Business Models and Monetization
-
Direct monetization is challenging in a decentralized ecosystem where everything is open-source and forkable.
-
They proposed potential monetization strategies such as premium support, finder’s rewards, and providing infrastructure services.
-
However, they emphasized that having a usable product should come before worrying about monetization.
Winner-Takes-All Market?
-
In the final market structure for rollups or appchain stacks, a winner-takes-all or winner-takes-most scenario may emerge due to the adoption of common-standard virtual machines.
-
Standard virtual machines offer many benefits, such as strong network effects and seamless interoperability across all these VMs.
-
Sovereign Labs and Slush differ in their approaches to achieving interoperability—Sovereign Labs emphasizes grassroots customizability, while Slush prioritizes scalability and aims to bring in as many applications as possible.
Attracting Developers
-
It's still too early to focus on business development and recruiting application developers. The current priority is building a product users will love.
-
There is massive demand for cheap transactions and blockspace—application developers want to run their own chains to offer cheaper services to users and capture revenue.
-
Demand will primarily come from new entrants in the space, and widespread adoption of these new architectures will take time.
Infrastructure and Developer Tools
-
It's crucial to build infrastructure for user onboarding, such as block explorers and developer tools.
-
They prioritize backward compatibility and sound design decisions to ensure existing tools and infrastructure continue to work.
-
They are still in the early stages of wallet design and may need more time before making any announcements.
Recap
-
Sovereign Labs is taking a full-stack approach to building application-specific rollups, whereas Slush opts for shared L2s on Ethereum.
-
It's important to strike a balance between distribution and development, as well as pay attention to brand positioning and market fit.
-
Remaining flexible and adaptive to market changes is crucial.
