Key Takeaways:
- Ethereum’s future hinges on simplifying its base protocol to increase resilience and reduce development overhead.
- Vitalik Buterin proposes replacing the EVM with a radically simpler and more efficient virtual machine like RISC-V.
- Standardizing core components across Ethereum layers may significantly cut protocol complexity.
Ethereum co-founder Vitalik Buterin has published a detailed proposal advocating for a radical simplification of Ethereum’s core protocol over the next five years.
His vision, outlined in a recent post titled “The Goal of Simplifying the L1,” draws inspiration from Bitcoin’s elegantly minimal design.
Ethereum’s transformation into a global ledger not only needs scalability and resilient infrastructure but also protocol architecture that is easy to reason about, understand, and upkeep.
Buterin reasons that Ethereum has been made increasingly complicated by years of iterative improvements, most of which yielded diminishing returns on the effort of the creators.
Referring to Bitcoin’s elegant block structure and consensus algorithm, Buterin feels that Ethereum can be equally elegant while not compromising its larger goals in finance, governance, and data validation.
With this in mind, Buterin proposes that there should be a line-of-code limit placed on the Ether protocol to keep its increasing complexity in check.
This, in turn, he thinks, would keep Ethereum from becoming dependent on some small group of technocratic elites and allow greater opportunities for participation in development and governance.
RISC-V’s Potential to Revolutionize Ethereum’s Execution Layer
The central part of Buterin’s proposal involves reviving Ether’s execution layer. He refers to increasing inefficiency in Ether’s EVM due to the fact that the environment has been over-engineered to function with outdated cryptography as well as specific edge cases.
Instead of making piecemeal reforms, Buterin suggests replacing the EVM with a far simpler virtual machine such as RISC-V.
ETH researcher Barnabé Monnot, who has extensively contributed to VM performance and zero-knowledge proofs, is in favor of this direction.
He observes that executing smart contracts natively on a machine based on RISC-V may bring more than 100x in execution performance improvements and eliminate most of the legacy code Ethereum now has.
This will also simplify formal verification, minimize bugs, and support more mainstream programming languages better.
Simplifying Ethereum’s Infrastructure
Buterin also emphasizes unifying multiple backends like erasure codes, serialization schemes, and Merkle trees. Currently, there are separate, often incompatible protocols that each component in Ether uses to do things that should be standardized.
By employing one serialization format such as SSZ and one erasure code across consensus, execution, and storage layers, Ethereum may be able to significantly cut back on duplication and resulting technical debt.
This under-the-radar route of simplifying by standardizing shared infrastructure may be Ether’s silent game-changer.
It is harmonious with the more aggressive proposals in the area of consensus and execution without impacting developers or users and may be the answer to keeping Ether both scalable and robust in the long term.
