Ethereum core developer and community thought leader c-node recently stated bluntly, "Unless you’re holding long crypto positions and want access to financial services while maintaining self-custody, there’s no reason to use DeFi." He dismissed most yield strategies based on stablecoins like USDC as "blind worship," arguing that they merely imitate the surface-level success of DeFi while betraying its original spirit.
At the heart of this debate lies a fundamental question: What truly counts as DeFi?
The State of DeFi and Questions of Value
On the surface, the decentralized finance sector of today’s crypto market appears to be booming, with a constant stream of new yield strategies and liquidity mining projects. However, Ethereum co-founder Vitalik Buterin sees deeper issues beneath this apparent prosperity. In his view, the vast majority of current DeFi applications primarily serve speculative capital rather than advancing the construction of truly decentralized financial infrastructure.
Echoing this critical stance, c-node points out that much of today’s DeFi activity is built on centralized assets like the stablecoin USDC. This, he argues, runs counter to DeFi’s core principles of self-custody and decentralization.
Technical shortcomings are also glaring. Vitalik’s recent criticisms of Ethereum Layer 2 solutions apply equally to the DeFi space. He notes that many L2 solutions only achieve superficial scaling, while key components such as cross-chain bridges remain under the control of a few participants—essentially turning them into "centralized databases dressed up as blockchains."
The Core Debate: What Is Real DeFi?
The crypto community is deeply divided over what constitutes "real DeFi." Vitalik argues that true decentralized finance must decentralize counterparty risk, not just optimize yields. He places particular emphasis on the importance of algorithmic stablecoins—especially those that are overcollateralized or structurally designed to distribute counterparty risk.
Vitalik explains, "Even if 99% of liquidity is backed by CDP holders with negative algorithmic dollars and positive dollars held elsewhere, the ability to shift counterparty risk onto market makers remains a key feature."
This debate highlights a deeper ideological rift within the crypto space. On one hand, DeFi is seen as a tool for boosting capital efficiency, leveraging assets, and generating yield while retaining custody. On the other, it’s viewed as a foundational system for reshaping the global financial sector through decentralization and risk distribution.
Ethereum Upgrades and the Future of DeFi
Despite his criticisms of current DeFi applications, Vitalik and many experts remain optimistic about Ethereum’s long-term prospects. The year 2026 is set to be pivotal for Ethereum, with the "Glamsterdam" upgrade scheduled for the second half of the year. This upgrade will introduce two key features: Enshrined Proposer-Builder Separation (ePBS) and Block-level Access Lists (BALs). While the technical details may seem complex to everyday users, the crucial point is that both improvements will significantly lower gas fees for users and DeFi applications.
At the same time, Glamsterdam will enable Layer 2 blockchains built on Ethereum to settle transactions on Ethereum with much higher throughput. If the upgrade rolls out as planned, the entire Ethereum ecosystem will become cheaper and more reliable.
Ethereum’s own scaling efforts are also opening new possibilities for DeFi. Core developers plan two major hard fork upgrades in 2026. The Glamsterdam upgrade will raise the gas limit from 60 million to 200 million—a more than threefold increase. In fact, the Fusaka upgrade completed in December 2025 already demonstrated the power of L1 scaling, boosting Ethereum’s daily transaction volume by about 50% and increasing active addresses by roughly 60%.
Market Outlook and Ethereum Value Analysis
Against the backdrop of DeFi controversy and technical progress, professional institutions remain cautiously optimistic about Ethereum’s market outlook. According to Gate market data, as of February 9, 2026, Ethereum is trading at $2,089.37 with a market cap of $252.82B, accounting for 10.04% of the total crypto market.
Technical upgrades and market demand must move in tandem. Standard Chartered Bank predicts that "2026 will be the year of Ethereum," citing its dominance in stablecoins, tokenized real-world assets, and DeFi as factors that could help it outperform Bitcoin. The bank projects Ethereum’s long-term price could reach $30,000. However, significant growth will still require favorable market conditions.
Looking at price ranges, Ethereum’s expected price in 2026 is between $1,320.02 and $2,283.84, with an average price forecast of $2,095.27. The long-term outlook is even more bullish: by 2031, the Ethereum price is projected to fluctuate between $2,863.02 and $4,481.25, with a potential return of +49.00%.
Ethereum’s long-term vision is to transition from a system denominated in dollars to one supported by decentralized collateral structures and diversified units of account. This shift will fundamentally transform DeFi infrastructure, aligning it more closely with decentralization principles. As the technology matures and new use cases emerge, Ethereum and its DeFi ecosystem are poised for more stable and sustainable growth.
The crypto market is undergoing a fundamental transformation. According to Messari’s 2026 Crypto Trends Report, DeFi is evolving toward modular lending protocols and active market-making AMM architectures. The stablecoin sector is also seeing new trends, with "yield-bearing stablecoins" gradually replacing passive stablecoins as the core collateral assets in DeFi.
Meanwhile, Ethereum itself is in the midst of a major transformation. As reported by ForkLog, L2 developers are engaged in heated debates with Vitalik over the future of Ethereum scaling. While the Arbitrum team insists that scaling remains the key value proposition of Layer 2 solutions, Karl Floersch of the Optimism Foundation advocates for further decentralization.
Jesse Pollak, head of Base, agrees with Vitalik, arguing that "L2s can’t just be ‘cheaper Ethereum.’" These developments show that while Vitalik’s criticisms of the current state of DeFi may be controversial, they do highlight fundamental issues that the crypto ecosystem must address. As Ethereum’s technology matures and the crypto market evolves, true decentralized finance may well be undergoing its necessary growing pains.
