Ethereum co-founder Vitalik Buterin has proposed a serious overhaul of the Ethereum base layer, aiming to simplify the protocol’s structure for improved safety, scalability, and long-term sustainability.
Drawing on Bitcoin’s minimalist design rules, Buterin revealed a weblog submit titled “Simplifying the L1” on Could 3, outlining a path to cut back the community’s technical complexity.
Buterin’s imaginative and prescient targets Ethereum’s core layers—consensus, execution, and shared elements—with a technique to streamline processes which have grown more and more convoluted for the reason that community’s inception.
Ethereum’s Complexity Is Slowing Progress and Elevating Dangers
Buterin argued that pointless complexity has led to bloated improvement timelines, increased upkeep prices, and elevated dangers of bugs.
A central factor of Buterin’s proposal is a reimagining of the consensus layer by way of a mannequin known as “3-slot finality.”
This method would get rid of intricate mechanisms comparable to epochs, sync committees, and validator shuffling.
By decreasing the variety of energetic validators at any given time, the protocol may undertake an easier and safer fork alternative rule, easing the event of sunshine shoppers and decreasing assault surfaces.

On the execution aspect, Buterin proposed transitioning from the present Ethereum Digital Machine (EVM) to a brand new, zero-knowledge (ZK)-friendly digital machine based mostly on the RISC-V structure.
RISC-V is a light-weight, open-source instruction set structure identified for its effectivity and ease.
The transfer may speed up ZK proof era by as much as 100x and make the protocol extra auditable and developer-friendly.
Buterin recommended sustaining backward compatibility in the course of the transition by working legacy EVM contracts by way of a RISC-V interpreter.
Buterin additionally known as for protocol-wide standardization to attenuate fragmentation.
He advisable consolidating instruments and codecs—comparable to adopting a single erasure coding methodology, serialization format (SSZ), and tree construction—to cut back redundant methods and improve developer tooling.
“Simplicity is in some ways just like decentralization,” Buterin famous, proposing that Ethereum undertake a “max line-of-code” precept for consensus-critical logic, very similar to the light-weight machine studying mission Tinygrad.
Below this method, non-critical or legacy options would nonetheless be supported however moved exterior the core specification.
Ethereum Has ‘Enormous Alternative’ to Repair AI’s Centralization Downside
Ethereum may play a key position in fixing a number of the most urgent issues going through synthetic intelligence, in response to Eric Connor, a former core developer of the blockchain.
Earlier this month, Connor stated Ethereum’s “largest mainstream second” may come by way of its integration with AI, because the sector struggles with centralization, opaque algorithms, and rising privateness considerations.
“AI is stricken by black-box fashions, centralized information silos, and privateness pitfalls,” Connor famous, including that Ethereum is uniquely positioned to handle these points.
Final month, crypto enterprise capitalist Nic Carter of Fortress Island Ventures pointed to 2 key points undermining Ether’s worth: the rise of layer-2 (L2) scaling networks and unchecked token issuance.
He argued that “grasping Eth L2s” are siphoning off worth from Ethereum’s base layer whereas giving little again.
He additionally criticized the Ethereum neighborhood’s acceptance of extreme token creation, claiming that “ETH was buried in an avalanche of its personal tokens. Died by its personal hand.”
