The Problem with Ethereum? Ex-Dev Says Progress Is Being Blocked

Ethereum’s complexity is increasing, making upgrades more difficult.
Internal disagreements are slowing EVM improvements.

Ethereum’s development path has become a topic of intense debate, with blockchain consultant Pascal Caversaccio highlighting concerns about the Ethereum Object Format (EOF).
In his view, the upgrade introduces unnecessary complexity and complicates maintaining and upgrading Ethereum further. Adding EOFCREATE5 and TXCREATE2 and removing and adding some opcodes further complicate the Ethereum Virtual Machine (EVM).

Caversaccio pointed out that the proposed benefits of EOF, such as compiler simplification and more efficient bytecode, would be achievable through less complex modifications.
He explained that eliminating JUMPDEST or changing existing validation rules would be more sensible than rewriting the entire system. He also didn’t think that EOF’s claim of making Ethereum more zero-knowledge (ZK) friendly holds strong justification.
The technical sophistication of EOF is also increased due to the fact that it necessitates continuous maintenance of legacy EVMs, massive tooling upgrades, and significant developer coordination.
The prospect of new vulnerabilities is also of concern, especially since major issues have been uncovered towards the end of the process. This uncertainty is making it harder for developers to adapt and is making them wonder about the long-term viability of Ethereum’s upgrade path.
Internal Disagreements Blocking Progress
Ex-Ethereum developer Hari also had a critical opinion of Ethereum’s governance due to the lack of a clear vision. He revealed that work within the EVM is repeatedly stalled due to disagreement among stakeholders.
He said the only substantive EVM upgrade in the past half-decade was for transient storage and that it nearly didn’t pass.

This is why I left the Ethereum Foundation.
There is a lack of a clear and cohesive vision for Ethereum and EVM, making progress in EVM impossible.
I’ve seen EVM changes repeatedly shut down because they don’t check a certain box. The issue is that everyone has a different… https://t.co/TkAngYnycX

Hari warned that Ethereum would become stagnant if decision-making becomes stuck. He suggested that the network needs to have a culture shift towards being comfortable with “disagree and commit.”
He asserted that without it, Ethereum would be left with ossification, where nothing new occurs, eventually leading it to decline.
Ethereum’s challenges are not just technical but also structural. While some believe complexity is inevitable due to real-world demands, others argue that excessive focus on research over practical development is slowing progress.
