For Vitalik Buterin, simplifying Ethereum is essential to true absence of trust

Ethereum's long-term strength may depend on more than scaling and security. According to co-founder Vitalik Buterin, true trust in the network also requires a broader understanding of how it works. He argues that simplifying Ethereum's protocol is essential. Without this, users must rely on a small group of experts rather than verifying the system themselves.

Overly complex protocols weaken lack of trust, according to Buterin

In a recent post on X, Buterin said that Ethereum already powers transactions and smart contracts through open-source code and a decentralized set of validators. This structure, he noted, theoretically supports decentralization. The real lack of trust, however, goes further. When only a small group of developers can understand or maintain a blockchain, ordinary users are forced to depend on them.

Buterin also argued that an often overlooked aspect of trustlessness is expanding the number of people who can follow the protocol from start to finish. A clearer system would enable more independent verification and reduce reliance on lead developers. Tradeoffs are inevitable, he added, and Ethereum should sometimes accept fewer features when complexity becomes an obstacle.

These concerns extend beyond Ethereum. Across the crypto industry, many projects struggle to attract ordinary users due to unclear storage practices, confusing interfaces, and dense technical language. Industry leaders have warned that these obstacles prevent even tech-savvy users from engaging with blockchain products.

Node barriers and complex wallets are holding Ethereum back, developers say

Privacy-focused projects have raised similar concerns, particularly around auditability. INTMAX, a privacy layer built on Ethereum, argued that lack of trust weakens when only a few experts can review a system. According to the team, simple, audited designs inspire more confidence than those built on components that are difficult to verify.

Developers and users often point out the same points of friction:

• Limited understanding of how protocols work behind the scenes.
• Technical jargon that discourages new users.
• High barriers to running nodes or verifying data.
• Wallet configurations requiring complex key management.
• Increasing reliance on specialists to interpret network changes.

Ethereum’s own roadmap reflects these challenges. Project leaders acknowledge that using Ethereum remains difficult for most people and maintain that lowering barriers to entry is a central goal. Current plans aim to make interactions with the network more like those of traditional Web2 applications.

Rise of rollups highlights Ethereum's scalability and usability challenges

Several improvements aim to improve the experience of participants in the Ethereum ecosystem. Smart contract wallets are designed to hide complex elements such as gas fees and recovery processes. Other efforts focus on enabling nodes to operate on lightweight devices, including phones and browser-based tools. Education is also a priority, with the Ethereum Foundation supporting courses and training programs for developers and users.

Alongside usability concerns, Buterin also highlighted that scalability is a major focus. It recently identified Peer Data Availability Sampling (PeerDAS) as a key step in meeting growing demand. With PeerDAS, nodes can confirm blocks without storing all the underlying data, instead relying on erasure coding. This reduces hardware requirements while maintaining security.

Recent network data shows Ethereum reaching six blobs per block for the first time, signaling increased use of rollups. This milestone reflects the growing pressure on the network and reinforces the need for designs that balance scale, security and clarity.
