Vitalik Buterin’s Bold Vision: Streamlining Ethereum’s Base Layer
In a move that could reshape the future of Ethereum, co-founder Vitalik Buterin has unveiled an ambitious plan to overhaul the network’s foundational structure. In his recent blog post titled “Simplifying the L1,” posted on May 3, Buterin draws inspiration from Bitcoin’s minimalist principles to propose a strategy aimed at enhancing Ethereum’s security, scalability, and long-term viability. With Ethereum facing rising complexities that threaten its performance, Buterin’s approach looks to untangle the intricate web that has developed since the platform’s inception.
Understanding Ethereum’s Convoluted Landscape
Buterin’s insights delve into a pressing issue: the unneeded intricacies embedded within Ethereum’s architecture have begun to hinder development and escalate risks. As the network has expanded, so too has its complexity, resulting in longer development timelines, increased maintenance demands, and a broader attack surface for potential bugs.
A pivotal element of Buterin’s proposal is the reimagining of Ethereum’s consensus layer through a model dubbed “3-slot finality.” This innovative approach endeavors to strip away complex mechanisms like epochs, sync committees, and validator shuffling, facilitating a simpler, more robust network operation. By concurrently reducing the number of active validators, the protocol can adopt a more straightforward and secure fork choice rule, ultimately fostering easier development of light clients and fortifying the network against malicious attacks.

Revolutionizing Execution: The Shift to RISC-V
On the execution front, Buterin proposes a transformative transition from the traditional Ethereum Virtual Machine (EVM) to a new virtual machine rooted in zero-knowledge (ZK) technology and based on the open-source RISC-V architecture. This cutting-edge move is anticipated to dramatically enhance the speed of ZK proof generation—potentially achieving increases of up to 100 times—making Ethereum not only more efficient but also more friendly to developers.
One of the key advantages of this transition is the ability to maintain backward compatibility. Legacy EVM contracts could be seamlessly run through a RISC-V interpreter, ensuring that older projects remain operational while embracing modernization. Furthermore, Buterin advocates for a protocol-wide standardization approach, which would involve consolidating tools and formats, such as implementing a unified erasure coding method, a serialization format (SSZ), and a streamlined tree structure. This move would alleviate fragmented systems, thereby smoothing out the developer experience.
“Simplicity is in many ways similar to decentralization,” Buterin articulately states, suggesting the adoption of a “max line-of-code” principle for critical consensus logic. This approach mirrors lightweight machine learning projects, like Tinygrad, which focus on efficiency and minimize unnecessary complexities. By pushing legacy features to the periphery, Ethereum can concentrate on core functionalities.
A Glimpse into Ethereum’s Future: Tackling AI’s Centralization Problem
Beyond mere functionality, Ethereum holds significant potential in addressing critical challenges facing the realm of artificial intelligence (AI). Eric Connor, a former core developer, recently highlighted that Ethereum’s “biggest mainstream moment” may come through its collaboration with AI technologies. With AI grappling with centralization, opaque algorithms, and privacy dilemmas, Connor posits that Ethereum is poised to provide innovative solutions.
As the crypto landscape evolves, concerns over Ethereum’s longevity and value have been voiced by notable figures, including crypto venture capitalist Nic Carter. He pointed out two challenges hurting Ether’s value: the burgeoning layer-2 (L2) networks and the unchecked issuance of tokens. Carter cautioned that “greedy Eth L2s” are siphoning value from Ethereum’s main network while offering little in return. Furthermore, he criticized the Ethereum community for its acceptance of rampant token issuance, remarking that “ETH was buried in an avalanche of its own tokens, dying by its own hand.”
Conclusion: What Lies Ahead for Ethereum?
Buterin’s vision for a restructured Ethereum base layer is not just a technical proposal; it represents a pivotal moment in the evolution of blockchain technology. As the discussions unfold, the Ethereum community finds itself at a crossroads. Will they embrace this bold vision for simplification and improvement? Can Ethereum leverage its strengths to solve pressing issues in the AI sector while overcoming its own internal challenges?
This is a compelling time for Ethereum, and the outcome of these proposed changes could shape the landscape of not only cryptocurrency but also the interconnected worlds of finance and technology. As we watch these developments unfold, the community is encouraged to engage in dialogue: What do you think about Buterin’s proposed changes? Are they the right steps towards a more sustainable future for Ethereum?
