Vitalik Buterin Proposes Ethereum PoS Enhancement for Efficiency

• Vitalik Buterin talks about streamlining Ethereum PoS for efficiency and reduced network load.
• He suggests cutting validator signatures to enhance Ethereum’s performance.
• He proposed changes to ensure manageable signature loads for Ethereum’s evolving protocol.

In a bid to streamline Ethereum’s proof-of-stake (PoS) consensus, co-founder Vitalik Buterin has put forth a proposal on December 28. The aim is to significantly simplify and lighten the network’s load by reducing the number of validator signatures. 

Ethereum currently supports an extensive 895,000 validators for decentralization, but this comes with technical challenges, requiring the processing of around 28,000 signatures per slot—a heavy load on the network.

Buterin’s proposal suggests a move to a more moderate solution with approximately 8,192 signatures per slot, down from the current 28,000. This adjustment would bring technical simplification, enhance quantum resistance, and maintain a significant total slashable ETH at approximately 1-2 million ETH, crucial for enforcing good validator behavior through slashing mechanisms.

The Ethereum co-founder outlined three potential approaches: reliance on decentralized staking pools, a two-tiered system with “heavy” and “light” staking, and rotating participation with accountable committees. These solutions aim to reduce the digital signature load to a manageable level while addressing the current minimum requirement of 32 ETH to become a validator, making it more accessible.

The proposed changes not only enhance technical aspects but also set a predictable path for the future signature load of the Ethereum protocol. By making it more manageable, Buterin believes it will simplify protocol and infrastructure development, allowing for potential adjustments through hard forks when technology improves sufficiently.

Vitalik Buterin had previously warned against overloading Ethereum’s consensus layer, emphasizing the importance of maintaining the core functions of validating blocks and securing the network without unnecessary strain. The proposed enhancements align with his vision of ensuring Ethereum’s efficiency and effectiveness in the evolving blockchain landscape.
