In a recent article published on January 23, 2025, Ethereum co-founder Vitalik Buterin delivered a comprehensive vision for the future of Ethereum’s Layer 1 (L1) and Layer 2 (L2) ecosystems. He emphasized not only technological advancement but also the importance of social coordination in sustaining a decentralized, scalable, and user-centric blockchain network. At the heart of his proposal is a clear directive: ETH should remain the primary economic asset across both L1 and L2 networks.
This vision comes at a pivotal moment as Ethereum continues to scale, with L2 solutions handling an increasing share of transactions. Buterin’s insights offer a roadmap for ensuring that growth doesn’t come at the cost of decentralization or the intrinsic value of ETH.
Ethereum’s Vision: Where Technology Meets Social Innovation
Vitalik Buterin stresses that Ethereum’s success isn’t solely due to its technical architecture—it’s equally rooted in social innovation. The network represents a large-scale social experiment in decentralized collaboration, moving away from traditional power structures toward open, permissionless participation.
Drawing from political philosopher Ahmed Gatnash’s observations on Devcon culture, Buterin highlights how the Ethereum community has cultivated a unique environment—one defined by cooperation, shared values, and resistance to centralized control. This social fabric supports technological progress, enabling Ethereum to evolve into one of the most influential ecosystems in the blockchain space.

A Decade of Progress: Ethereum’s Real-World Utility
Over the past ten years, Ethereum has transitioned from a conceptual platform to a widely used infrastructure with tangible applications:
- Millions use ETH and stablecoins for savings and payments.
- ENS (Ethereum Name Service) provides a decentralized alternative to traditional DNS.
- DeFi (decentralized finance) platforms offer accessible, high-yield financial tools with minimal counterparty risk.
Compared to just five years ago, smart contract security has improved dramatically. Infrastructure is more robust, transaction costs are significantly lower, and user adoption has expanded globally. Much of this progress can be attributed to the rise of Layer 2 scaling solutions, which offload computation from the main chain while maintaining Ethereum’s security guarantees.
The Rise of L2: Solving Ethereum’s Scalability Challenge
Rapid Advancements in L2 Technology
Since their experimental beginnings in 2019, L2 protocols have matured into secure, high-performance networks. Today, they enable 17x higher transaction throughput than Ethereum’s base layer, drastically reducing fees and making DeFi, social apps, and prediction markets more accessible.
However, challenges remain:
Challenge 1: Data Capacity Limits on L1
Ethereum’s current data storage capacity is barely sufficient for existing demand. As more applications migrate to L2s—especially those requiring frequent data availability—the strain on L1 will intensify.
Buterin proposes increasing the number of "blobs" per block—temporary data storage units introduced via EIP-4844. Currently set at three blobs per slot, this limit could be raised through future upgrades like PeerDAS and 2D sampling, potentially enabling 100,000 transactions per second.
Challenge 2: Fragmentation Across L2s
With multiple teams building independent L2s using different architectures and standards, interoperability becomes a major hurdle. Users face inconsistent experiences when moving assets or interacting across chains.
This fragmentation undermines the promise of a unified Ethereum ecosystem.
Scaling the Future: A Multi-Pronged Strategy
To address these challenges, Buterin outlines a strategic path forward across three key areas:
Accelerating L1 Upgrades: More Blobs, Greater Efficiency
The immediate priority should be enhancing L1’s data throughput. Increasing blob capacity allows more data to be posted cheaply by rollups, improving scalability without sacrificing decentralization.
Future improvements like PeerDAS (Peer Data Availability Sampling) and 2D erasure coding will allow validators to verify large datasets efficiently. Buterin urges the community to prioritize blob-related upgrades and even consider dynamic blob targets that adapt based on network conditions.
Strengthening L2 Security
Many current L2s rely on temporary security models such as multi-signature guardians, which introduce centralization risks. To achieve true decentralization, two paths are recommended:
- Multi-prover systems combined with formal verification—ensuring mathematical correctness of rollup proofs.
- Development of native rollups, where proof systems are embedded directly into the Ethereum protocol layer.
These changes would eliminate trust assumptions and align L2 security fully with Ethereum’s base layer.
Improving Interoperability and User Experience
For Ethereum to function as a cohesive ecosystem, seamless interaction between L2s is essential. Buterin advocates for standardization efforts such as:
- ERC-3770: A unified cross-chain address format.
- Trustless bridging protocols to enable secure asset transfers.
- Faster withdrawal times and consistent UX across rollups.
The goal? Using any L2 should feel no different than using Ethereum itself—like browsing websites on the same internet.

Reinventing ETH’s Economic Role
As L2 activity grows, there’s a risk that ETH could become marginalized—used only for L1 gas rather than as the dominant economic asset across layers. Buterin warns against this trend and proposes reinforcing ETH’s centrality:
- Burn ETH in L2 transactions, creating deflationary pressure and tying usage directly to value accrual.
- Use ETH to fund public goods within the ecosystem via mechanisms like quadratic funding.
- Expand revenue streams through blob transaction fees, which could become a significant source of income for stakers.
- Explore sustainable MEV (Maximal Extractable Value) sharing models that benefit the broader network instead of enriching a few actors.
By anchoring economic activity around ETH across all layers, the ecosystem ensures long-term alignment between users, developers, and validators.
The Road Ahead: Collaboration Is Key
Vitalik’s vision is not just technical—it’s deeply communal. The next phase of Ethereum’s evolution depends on coordinated action from developers, researchers, node operators, and ETH holders alike.
From boosting data efficiency to securing rollups and unifying user experience, every upgrade must serve the broader mission: a more open, accessible, and resilient digital world.
But this transformation won’t happen automatically. It requires ongoing investment in research, open dialogue within the community, and a shared commitment to decentralization.
Frequently Asked Questions (FAQ)
Q: What are blobs in Ethereum?
A: Blobs are temporary data storage units introduced by EIP-4844 to reduce costs for Layer 2 rollups. They allow large amounts of transaction data to be posted efficiently on Ethereum while being deleted after ~18 days to save space.
Q: Why is interoperability between L2s important?
A: Without standardized communication and asset transfer protocols, users face friction moving between networks. Seamless interoperability ensures Ethereum functions as a single virtual blockchain rather than a fragmented collection of silos.
Q: How can ETH remain valuable if most transactions happen on L2s?
A: By integrating ETH into L2 economics—such as charging fees in ETH or burning it during transactions—the asset retains utility and demand even as activity scales off-chain.
Q: What is a native rollup?
A: A native rollup is a scaling solution whose proof system is built directly into Ethereum’s consensus layer. This enhances security and reduces reliance on third-party validators or trusted bridges.
Q: Is increasing blob count safe for decentralization?
A: Yes—when paired with technologies like PeerDAS and 2D sampling, higher blob counts can be verified efficiently even by modest hardware, preserving Ethereum’s decentralized validator set.
Q: What role does MEV play in Ethereum’s future?
A: MEV represents extractable value from transaction ordering. While it poses risks if centralized, fair distribution mechanisms—like MEVBoost with proposer-builder separation—can turn it into a sustainable revenue stream for stakers.
