Vitalik Buterin, the co-founder and core developer of Ethereum, has unveiled his latest vision for the world’s second-largest blockchain to drastically simplify its Layer 1 (L1) protocol over the period of the next five years.
In his latest blog post titled “Simplifying the L1,” shared on May 3, Buterin outlined a strategy to follow Bitcoin’s minimalist design in addressing Ethereum’s long-standing challenges with complexity, high development costs, and security vulnerabilities.
The proposal seeks to position Ethereum as a more resilient and efficient “world ledger” for finance, governance, and high-value data authentication.
Buterin’s plan centers on reducing Ethereum’s complexity, which has ballooned over the years with a codebase now exceeding 300,000 lines, compared to Bitcoin’s lean 15,000 line consensus code.
While the increased code lines enable advanced features like smart contracts and decentralized applications (dApps), it has also led to significant security risks on the network. The infamous 2016 DAO hack is a prime example for this, where a flaw in a smart contract allowed attackers to siphon $50 million in ETH.
To address this issue, Buterin’s boldest suggestion is to implement a maximum code line limit for Ethereum’s core protocol. By trimming it to a more manageable size, Buterin aims to shrink Ethereum’s attack surface. This would make it easier to audit and maintain while reducing the likelihood of costly exploits.
“Simplicity, like decentralization, is upstream of resilience,” Buterin wrote, emphasizing the long-term benefits of a leaner Ethereum despite the short-term challenges of implementation.
The proposal also includes significant technical shifts to enhance performance and scalability. Buterin advocates replacing the Ethereum Virtual Machine (EVM) with a RISC-V virtual machine, an open-source instruction set architecture known for its efficiency.
This shift from EVM to RISC-V virtual machine could improve zero-knowledge proof performance by 50-100x, potentially lowering gas fees and making Ethereum more competitive with newer blockchains like Solana, which have gained market share due to their speed and cost-effectiveness.
Additionally, Buterin also calls for protocol-wide standardization, such as adopting a single erasure coding method, serialization format (favoring SSZ), and tree structure. These changes aim to eliminate redundant complexity, streamline tooling, and make Ethereum more accessible to developers.
The move from the Ethereum developer comes at a critical time as Ethereum continues to lose ground to competing blockchains. As the network now embarks on this ambitious five-year journey, his vision could redefine Ethereum’s role in the blockchain ecosystem, with it balancing innovation and stability.
Whether this push for simplicity will solidify Ethereum’s position or spark new challenges remains to be seen, but one thing is clear: the debate over complexity versus simplicity in blockchain design is far from over.
