The Limitations of Rollups: A New Approach to Blockchain Architectures is Needed
As a co-founder of Anoma, I have been closely following the development of rollups as a solution to Ethereum’s scalability issues. While rollups have become the go-to answer for many in the space, I firmly believe that they are not the panacea we’ve been led to believe. In fact, their limitations and drawbacks are becoming increasingly apparent.
The Problem with Rollups
Rollups are essentially copies or slight modifications of the Ethereum Virtual Machine (EVM). While they reduce transaction fees by moving computation off the main chain, they do not address the need to scale state or drive new use cases or innovation. It is the same for alternative virtual machines (altVMs), as they provide developers with new programming language options. However, altVMs do not fundamentally bring new functionality to the ecosystem.
Rollup usage has primarily been dominated by points farming schemes, lacking practical applications to move the space forward. Rollup proliferation results from a broken, fragmented state and liquidity landscape that limits user and developer experience and adoption.
The True Scalability Challenge Lies in Data and State
Rollups alone are not proper scaling solutions. It would be more accurate to define them as an execution-sharding solution. Scaling computing is not a complex problem — the complicated problem is scaling state and data access and distribution. Rollups still rely on Ethereum for data availability and security. While this improves transaction processes, it does little to increase Ethereum’s base layer capacity in the long run.
Although zero-knowledge (ZK) rollups provide significant cryptographic advancements and are moving us away from the need to do everything on-chain, the ecosystem does not need 200 different copies or slight modifications of the EVM, each with its decentralized exchange (DEX).
Rollups currently don’t do enough to address the real bottleneck in blockchain scalability: data storage and state management. We need solutions that can scale data and state.
Plasma and Intents Will Unlock True Scalability and Spark Innovation
The only viable solution currently for true scalability is Plasma-like constructions. Plasma eliminates reliance on a single data availability layer. It enables a world where significant data and computing can be kept off-chain — e.g., on users’ edge devices.
The amount of data a rollup needs to post to the main chain is proportional to the amount of usage it gets, which is not a proper scaling solution. With Plasma, we can post a constant amount of data to the main chain regardless of user throughput.
Scalability is not the only challenge. We also need to ignite innovation at the application layer. New approaches to blockchain architectures and new primitives for application development are necessary. That’s where intent-centric architectures come into play.
Intents: A New Paradigm for Building Decentralized Applications
Intents provide a new paradigm for building decentralized applications that abstract away the complexity of blockchain infrastructure for users. Intents only care about the ‘what’ and are less concerned with the ‘how,’ requiring users to define what they want to achieve without prescribing the intermediate steps needed.
Building DApps on an intent-centric operating system enables developers to tap into state and liquidity from anywhere in the Ethereum ecosystem (including layer 2s) and use the Ethereum main chain (or any layer 2) as the settlement layer. Generalized intents can facilitate the shared sequencing of Ethereum rollups, defragmenting states across chains and allowing developers to treat the entire multichain landscape as a unified development environment.
Unlocking Blockchain’s True Potential with Intents
The blockchain space needs to evolve beyond its current infrastructure focus to build user-friendly applications that offer real utility. Rollups are essential to Ethereum’s evolution, but intents can help them uncover a new wave of innovation. It’s time to question if we are building technology that solves fundamental issues or just creating more complexity.
Only by being bolder in our innovations and more focused on solving fundamental issues can we hope to realize the ultimate vision of blockchain technology: to bring sovereignty and resilience to the systems we rely on daily.
