Ethereum co-founder Vitalik Buterin has raised concerns over a critical issue affecting the network’s performance, specifically related to the modular exponential computation, known as modexp. Buterin pointed out that modexp imposes a heavy computational burden on the network, significantly impacting its efficiency and compatibility with ZK-EVM technology. He suggested a revision to the EVM code that, although might lead to increased gas fees, is essential for bolstering both network security and performance.
How Does Modexp Affect Ethereum?
Buterin, through social media updates, highlighted how modexp contributes to inefficiencies within the Ethereum network, particularly hampering the ZK-EVM proving processes and consensus security. He emphasized that ZK-EVM technology is critical for the network’s scalability, but components like modexp are significant impediments.
Could SNARK Be a Better Alternative?
SNARK, as advocated by Buterin, offers a more efficient approach to handling the encryption and signing tasks usually managed by modexp. These alternatives could streamline verification processes, thus reducing overall transaction costs and network congestion.
Buterin criticized the focus on optimizing modexp, which benefits a minuscule proportion of users, suggesting that resources should be redirected to broader network improvements. He conveyed the importance of strategic resource allocation to enhance overall efficiency.
Highlighting modexp’s predominant role in RSA-based encryption, Buterin proposed a transition to SNARK-based solutions. This shift, he noted, could simplify and expedite network operations.
According to Buterin,
“Modexp genuinely pulls Ethereum significantly backward,”
signalling that the complexity of modexp has led to previous consensus errors and posed risks to network stability.
Key takeaways from Buterin’s analysis include:
- Modexp adds substantial computational load, needing revision for better efficiency.
- ZK-EVM technology’s scalability is hindered by current network inefficiencies.
- Adopting SNARK could improve verification speed and reduce costs.
Updating the foundational elements of the Ethereum network as Buterin suggests could pave the way for enhanced performance, robust security, and more streamlined operations, ultimately aligning with the evolving demands of blockchain technology.
