Vitalik Buterin: Ethereum's Scaling Roadmap Must Evolve as L1 Outpaces L2 Vision

Ethereum co-founder Vitalik Buterin has publicly stated that faster-than-expected progress on Ethereum's Layer 1 scalability, combined with slower-than-anticipated Layer 2 adoption, is forcing a fundamental reassessment of the network's scaling strategy. Buterin argues that rollups must evolve beyond their original role as simple throughput solutions, taking on a broader set of responsibilities in the ecosystem. The statement signals a potential pivot in how the Ethereum Foundation thinks about long-term architecture and the relationship between L1 and L2. This comes amid ongoing debates about L2 fragmentation — a topic that has dominated recent EthCC discussions.

Aztec Launches Alpha Network: Ethereum's First L2 for Private Smart Contracts

Aztec Network — backed by a16z — has launched its alpha network, marking the debut of Ethereum's first Layer 2 designed specifically for private smart contracts. The launch enables confidential on-chain computation, a capability long sought by enterprise and privacy-focused users. However, Aztec is being unusually transparent: the team explicitly warns users of known critical vulnerabilities while security audits remain ongoing. The cautious rollout reflects the complexity of building privacy-preserving infrastructure at scale on Ethereum.

Uniswap Foundation Reports $85.8M Treasury, Runway Through 2027

The Uniswap Foundation has published its FY2025 financial report, disclosing total assets of $85.8 million and a projected operational runway extending into early 2027. The report details ongoing grant programs, operational expenses, liquidity management, and governance tooling development. The foundation emphasized continued investment in ecosystem growth and developer support. The disclosure comes as Uniswap remains a dominant DEX protocol across Ethereum and its L2 ecosystem.

Layer 2 & DeFi Dashboard

Note: Live TVL figures from DefiLlama could not be fully extracted from the screenshot. The Base figure reflects peak October 2025 data per The Block's 2026 L2 Outlook report. Readers should verify current figures at .

Base's trajectory has been the defining L2 story heading into 2026, having surpassed Arbitrum as the largest Ethereum rollup by TVL and capturing roughly 46.6% of all L2 DeFi TVL at its October 2025 peak. With Vitalik now publicly questioning whether L2s are living up to their original vision, expect increased scrutiny on whether that locked value is genuinely expanding Ethereum's economic footprint or merely redistributing it. Aztec's privacy L2 launch adds a new dimension — confidential DeFi — that could unlock entirely new TVL categories if audits conclude successfully.

Protocol & Governance Updates

• Ethereum Roadmap — Glamsterdam Upgrade: The Ethereum Foundation's January 2026 Checkpoint noted that the two headline features for the upcoming "Glamsterdam" fork — enshrined Proposer Builder Separation (ePBS) and Block-level Access Lists (BALs) — are advancing on devnets. BALs already have active devnets, while ePBS, described as a "much more complex change," is still working toward its first devnet. No upgrade date has been announced; both features must reach stability on devnets before additional EIPs are added to the fork.

• Ethereum Scaling Architecture Debate: Vitalik Buterin's public statement that Ethereum's scaling roadmap must evolve — given faster L1 progress and L2 shortfalls — is expected to influence upcoming EIP priorities and may reshape discussions at the next All Core Developers call. Developers and researchers are being asked to consider how rollups should be repositioned in the broader architecture.

Ecosystem Projects

• Aztec Network (Privacy L2): The a16z-backed project went live with its alpha mainnet, delivering private smart contract capability to Ethereum users for the first time via an L2. The team openly disclosed that known critical vulnerabilities exist and that security audits are still underway — an unusual but notable level of transparency. Users are advised to proceed with caution until audits are complete.

• Uniswap Foundation: Published its full FY2025 annual financial report, revealing $85.8M in total assets and confirming the organization has sufficient runway through early 2027. The report outlines grant disbursements, operational costs, liquidity positions, and the foundation's ongoing governance tooling work supporting the Uniswap DAO.

• DeFi Development Corp. (DFDV): The Nasdaq-listed company, which holds Solana's SOL as a treasury asset, issued a public statement confirming it has zero exposure to the Drift Protocol following a reported ~$285M exploit on the Solana-based trading platform. The clarification was notable given DFDV's profile as a publicly traded DeFi-adjacent firm, and underscores growing institutional sensitivity to DeFi security incidents.

What to Watch

• Aztec Audit Completion: With known critical vulnerabilities disclosed at launch, the conclusion of Aztec's security audits will be a critical moment for Ethereum's nascent privacy L2 space. Watch for audit firm announcements and any vulnerability disclosures in the coming weeks.

• Vitalik's Scaling Roadmap Proposal: Buterin's call to evolve the scaling roadmap is likely to surface as a formal discussion item at the next All Core Developers call. Developers and stakeholders should monitor ethereum/pm on GitHub for agenda updates.

• Glamsterdam Devnet Progress (ePBS): The Ethereum Foundation's Checkpoint noted ePBS devnets are "a bit longer" away than BALs. Any new devnet announcement for ePBS would signal the upgrade timeline is firming up — a key milestone to track for 2026 mainnet planning.
