Vitalik Buterin published an extensive discussion of X in which he argued for a central idea. That is, for a protocol to be truly reliable, autonomous, and durable, it must be simple.
In their vision, it is not enough to have thousands of nodes or a high level of fault tolerance if the underlying software breaks. Most developers don’t understand it.
Buterin argued that overly complex protocols are no longer “trustless.” forced to rely on a small group of experts I’ll explain how it works.
Mr. Vitalik emphasized: Complexity threatens user sovereigntyBecause we cannot fully own what we cannot understand.
The network’s co-founder also warned: Excessive complexity also reduces the security of the protocolThis is because additional components and their interactions increase the risk of failure.
In that sense, he suggested that Ethereum needs to move out of its “adolescent” phase of constant experimentation and slow down the pace of change to prevent unhelpful ideas from becoming a permanent burden on the protocol in the long run.
The framework warned of a recurring risk in protocol development: adding certain features without removing old components.
Vitalik left an image explaining his idea under the message: “Basically, we want to improve Ethereum in the following ways.”
This publication by Buterin coincides with another recent publication, as recently reported by CriptoNoticias. Network does not exceed « Evidence of abandonment«. This takes into account that it is very difficult for a new team to reproduce the technical level if the current client is gone.
Vitalik Buterin’s proposal
Ethereum’s co-founders believe that simplifying the network comes first. Reduction in total protocol code. Ideally, it should be understandable in just a few pages.
Additionally, it suggests Avoid unnecessary dependencies on technical components It becomes extremely complex as each new layer of encryption increases vulnerabilities and makes the system difficult to audit and understand.
Similarly, he emphasizes The importance of incorporating more invariantsThat is, they are basic, stable rules that protocols can rely on.
The Russian-Canadian’s goal is to simplify customer development and facilitate future technologies such as zero-knowledge (ZK) proofs and virtual machines with parallel execution.
Responses from Ethrex and Argentina
Buterin’s reflections found a direct response from Latin America.
Fede Intern, one of the main collaborators of Lambda Class, an Argentinian company developing an execution client for Ethereum ethrex, assured:
In the coming weeks, it will become clear that the ethrex client is literally doing exactly this on an engineering level for Ethereum.
Fede Internet, developer of ethrex software.
This comment suggests that ethrex is materialized in the code as follows: Buterin’s philosophy of simplicity.
CriptoNoticias reported on the development of the Lambda class team in mid-2025. Currently, the ethrex software is already running on Ethereum, so Fede Intern’s comments may reflect future updates.
Ethrex is an Ethereum execution client developed by a team in Argentina. minimalist, modular, stable. According to its repository, the goal is to reduce software complexity without sacrificing functionality.
The team says the project is written in the Rust programming language, with clean code, a small number of external dependencies, and An architecture that is easy to audit and scale.
