For years, Ethereum has been engaged in a relentless race towards complexity, multiplying features and technical layers. But today, Vitalik Buterin, its visionary co-founder, proposes a return to basics: simplifying the protocol to make it more readable, more stable, almost as simple as Bitcoin. A paradigm shift? Maybe. But above all, a vital necessity at a time when Ethereum wishes to remain the reference layer 1 for layer 2 solutions and the digital assets of the future.
The goal of Vitalik Buterin is clear: to make Ethereum a protocol understandable “by a smart high school student“. To do this, he wants to limit the critical code to the essentials, similar to Bitcoin. The 3-slot finality consensus is one of the keys to this simplification. This model eliminates complex components like epochs, synchronization committees, and validator reshuffling. Result: a simpler, more readable, and faster consensus than the current Gasper protocol.
Buterin points out that “a basic implementation of 3-slot finality fits in 200 lines of code“. Fewer lines of code means fewer bugs, wider developer involvement, and a reduction in technical elitism.
Sassal.eth adds:
A simplified L1 also makes solo staking more accessible.
The Ethereum Virtual Machine (EVM) has become a technical nightmare: 256-bit architecture, useless opcodes, costly maintenance. Buterin proposes a radical leap: replacing the EVM with RISC-V, a simple and standardized virtual machine. This transition could offer performance gains estimated at x100 for zero-knowledge proofs (ZK), while reducing the need to maintain complex precompilations.
The transition would be gentle: an on-chain EVM interpreter would enable coexistence with the old contracts. Sassal.eth highlights the importance of this evolution:
We want tokens to be natively deployed on L1.
Key points:
Currently, Ethereum uses multiple serialization formats and Merkle tree structures. Buterin wants to unify these elements around SSZ for storage, transmission, and execution. He also proposes adopting a single error-correcting code for all functions (DAS, P2P, storage). The goal is to reduce duplication, maximize verifiability, and improve system readability.
Sassal.eth emphasizes the importance of this unification:
All digital assets should be natively issued on L1.
Buterin summarizes this vision by stating:
The goal is to move as much complexity as possible out of the consensus.
Ethereum aspires to become a solid foundation again, a clear base for a broader ecosystem. By rethinking its layer 1, it hopes to attract developers, asset issuers, and restore trust. Buterin, already the author of a decisive plan for the survival of his own blockchain, thinks far ahead, and so does Sassal.eth. And while the world turns to layer 2 solutions, Ethereum strengthens its foundations to better remain the center of gravity of decentralization.
