Unified Ethereum? Devcon panelists take on fragmentation challenges

Some of Ethereum’s foremost thinkers tackled Ethereum’s evolving identity and the challenges of unifying its fragmented ecosystem during a Devcon panel today in Bangkok.

Vitalik Buterin, Stephen Goldfeder, Ben Jones and Jesse Pollack, discussed the problems faced by Ethereum and its rollup-centric roadmap, fielding questions from Hart Lambur of Uma and Across Protocol.

Lambur highlighted the progress Ethereum has made, enabled by “blobs” that slashed layer-2 costs and increased transactions per second (TPS). Yet, Ethereum’s rapid scaling has led to fragmentation, sparking concerns about interoperability and user experience.

Buterin lamented the current need for custom solutions whenever users operate across multiple chains. He likened the ideal Ethereum experience to credit card use in Web2, where everything seamlessly connects behind the scenes.

“If Ethereum cannot meet that level of experience,” Buterin warned, “it’s going to lose to things that do.” Still, he praised the commitment of L2 and wallet developers tackling these challenges head on.

The panel discussed a crucial concern: the competition for users and developers among Base, Optimism, and Arbitrum, each vying for liquidity and mind share. Stephen Goldfeder voiced a shared sentiment: Users shouldn’t be burdened with infrastructure complexities. He advocated for a “unified Ethereum,” envisioning seamless transitions across chains within the ecosystem.

Jones and Pollack each echoed the need for interoperability without restrictive silos, referencing Ethereum’s Superchain vision to support user-friendly, cross-chain interactions, suggesting the competition between the major “constellations” of L2 networks is a bit of an illusion.

A key challenge lies in bridging technical and experiential gaps. While Jones argued that EVM-equivalence should theoretically simplify deployment, current reality presents high overhead for developers.

Vitalik stressed the need for easier asset movement across chains and agreed with Pollack that interfaces which “hide addresses,” that often confuse users in favor of names, would help. Pollack’s focus on simplicity in wallets and interfaces, underscored Base’s focus on building “open source on open standards,” aimed at empowering users even if centralized entities — like Coinbase — were to fail.

Among the concrete steps the panel explored was the need for on-chain configurations for L2 networks. Parameters such as chain IDs and other identifiers, are foundational for distinguishing each L2 within the Ethereum ecosystem. By establishing standard data points across these networks, wallets, dapps and users can easily recognize and interact with various L2s without needing custom configurations for each one. Expanding these standards could enable deeper interoperability and more seamless interactions between L2s.

One significant benefit of standard on-chain configs is the potential for a universal light client — a tool that verifies and interacts with multiple L2s without requiring chain-specific adaptations. That way a single light client could authenticate transactions and verify data across all participating L2s. This reduces technical friction, creating a more integrated network where assets, data, and applications flow easily across chains.

Standardized protocols like RIP-7755 and ERC standards that don’t require protocol changes could facilitate cross-chain operations, including advanced proof structures, Pollack said.

Jones and Buterin emphasized the long-term goal of bringing rollups to Stage 1 or 2, to mitigate inherent governance risks. Fast, secure bridging was recognized as an urgent need, especially with a push for wallet innovations that incorporate chain abstraction.

Ultimately, the panel articulated a shared mission: enhancing user experience without compromising Ethereum’s decentralized ethos, aiming for an ecosystem where users, not chains, remain at the center.
