Vitalik Buterin Alerts of Ethereum’s “Cumbersome Chaos” — Calls for Immediate Protocol Overhaul

Vitalik Buterin, co-founder of Ethereum, is cautioning that Ethereum may risk transforming into an “unmanageable tangle” unless developers start prioritizing the simplification of the protocol instead of perpetually adding new functionalities.

In a message shared on X on Sunday, Buterin expressed that Ethereum’s greatest danger lies not in competitive threats but in its internal complexity.

A significant and often overlooked element of “trustlessness”, “passing the walkaway test”, and “self-sovereignty” is the simplicity of the protocol.

He contended that decentralization, trustlessness, and self-sovereignty become meaningless if the protocol is so intricate that only a limited number of specialists can comprehend or maintain it.

His comments arise at a time when Ethereum is experiencing unprecedented transaction activity alongside historically minimal fees.

Buterin Highlights ‘Protocol Bloat’ in Ethereum’s Codebase

Buterin pointed out that even a network boasting hundreds of thousands of nodes and robust fault tolerance fails its fundamental mission if its codebase evolves into layers of complex cryptography that only a few can audit.

His primary concern is what he refers to as protocol bloat.

He mentioned that Ethereum’s development history has often leaned towards adding features while seldom removing older ones, primarily to maintain backward compatibility.

Over time, this results in a protocol that becomes heavier, increasingly difficult to navigate, and more fragile.

Buterin cautioned that such intricacy compromises security, elevates the entry barrier for new client teams, and diminishes Ethereum’s resilience should current core developers withdraw.

To address this trend, Buterin advocated for a clear “simplification” or “garbage collection” function within Ethereum’s development framework.

He stated that simplification should aim at reducing the total lines of code, decreasing dependence on complex cryptographic elements, and establishing stronger invariants to enhance the predictability of client behavior.

Buterin Proposes Strategy to Reduce Complexity in Ethereum

He cited past modifications, such as the elimination of the SELFDESTRUCT opcode and transaction gas limits, as instances where thoughtfully selected constraints can facilitate easier implementation and safer operation of the protocol.

Buterin also suggested broader cleanup strategies, including transferring infrequently used or intricate features from the core protocol into smart contracts.

With this approach, legacy transaction types, precompiles, and even the Ethereum Virtual Machine itself could eventually be downgraded from essential protocol components, enabling new clients to concentrate on a more straightforward core.

The overarching aim, he indicated, is for Ethereum to successfully pass what he terms the “walkaway test.”

This entails achieving a state where Ethereum’s value proposition remains intact, even if active protocol development slows or ceases.

Ethereum’s Future Path Sparks Strong Contrast With Solana

In a post from January 12, Buterin articulated that Ethereum must be capable of ossifying if it decides to, with all critical features already established.

These enhancements encompass quantum-resistant cryptography, a scalable architecture centered on ZK-EVMs and PeerDAS, full account abstraction, a secure gas schedule, and a proof-of-stake mechanism that can remain decentralized for decades.

Buterin’s call for simplification has faced some resistance. On January 18, Solana co-founder Anatoly Yakovenko publicly dismissed the notion of protocol ossification, asserting that blockchains must “never cease to iterate” to maintain their usefulness.

Yakovenko argued that Solana’s survival hinges on ongoing adaptation propelled by developers whose livelihoods depend on the network, portraying stagnation as a more significant risk than complexity.

His statements come amidst notable technical advancements on the network.

Currently, Ethereum is processing nearly 2.5 million transactions daily, while the average gas fees have reduced to approximately $0.15.

Recent upgrades, including the Fusaka hard fork and adjustments to blob parameters, have increased capacity and lowered costs, primarily through enhanced layer-2 utilization.

Simultaneously, Ethereum’s staking dynamics have shifted positively.

The validator exit queue has dropped to zero, while entry queues have reached multi-year peaks, reflecting diminished sell pressure and heightened confidence in Ether as a yield-generating asset.
