Ethereum co-founder Vitalik Buterin has declared that the community’s long-term survival relies on drastically simplifying its protocol.
In a January 18 put up on X, Buterin argued that the blockchain is turning into too dense for unbiased verification. In response to him, extreme technical complexity threatens its elementary sovereignty.

Ethereum Co-founder Advocates for Code ‘Garbage Collection’
He argued that counting on “PhD-level cryptographies” and more and more bloated code dangers narrowing Ethereum’s accessibility. In that situation, the community may drift towards a technocratic mannequin relatively than stay a decentralized public good.
An essential, and perenially underrated, side of “trustlessness”, “passing the walkaway test” and “self-sovereignty” is protocol simplicity.

Contemplating this, he restated the idea of the “walkaway test” as a important benchmark for fulfillment. This check measures whether or not the blockchain may proceed to function securely if its unique founders and core researchers completely left the mission.
Buterin warned that Ethereum at present dangers failing this check as a result of its operations are too advanced for brand new groups to handle with out knowledgeable steering.
He defined that builders are sometimes keen so as to add new options to attain short-term performance. Over time, that behavior creates technical debt he described as “highly destructive” to the community’s future.
“One of my fears with Ethereum protocol development is that we can be too eager to add new features to meet highly specific needs, even if those features bloat the protocol or add entire new types of interacting components or complicated cryptography as critical dependencies,” he wrote.

To counter this, Buterin known as for an specific “garbage collection” perform throughout the growth course of—a mandate to delete out of date code and dependencies.
“Garbage collection can be piecemeal, or it can be large-scale. The piecemeal approach tries to take existing features, and streamline them so that they are simpler and make more sense,” he defined.
Contemplating this, he mentioned the trail ahead relies on three concrete metrics. These embody minimizing whole protocol code, decreasing reliance on advanced elements, and growing the variety of self-sufficient invariants.
Buterin pointed to Ethereum’s transition from Proof-of-Work to Proof-of-Stake as a profitable instance of this philosophy in motion.
He framed the transition not merely as an improve, however as a crucial purge of legacy mechanisms that had turn out to be inefficient.
In the meantime, this disclosure indicators a possible slowdown within the rollout of experimental options. The community seems to be prioritizing its evolution right into a verifiable, automated settlement layer.
“In the long term, I hope that the rate of change to Ethereum can be slower. I think for various reasons that ultimately that _must_ happen. These first fifteen years should in part be viewed as an adolescence stage where we explored a lot of ideas and saw what works and what is useful and what is not,” Buterin said.
By prioritizing auditability over complexity, Buterin goals to make sure Ethereum stays safe with out requiring a centralized staff of specialists to keep up it.
