Ethereum’s EIP-7781: Faster Blocks, 50% More Throughput

• Ethereum’s EIP-7781 is set to cut block times by 33% and enhance throughput by 50%.
• This initiative seeks to improve network efficiency without pushing peak bandwidth limits.
• Though many developers are gravitating towards Ethereum Layer 2 solutions, EIP-7781 represents a key advancement for Ethereum’s core architecture.

On October 5, 2024, an exciting new proposal, Ethereum’s EIP-7781, emerged with the potential to significantly enhance the Ethereum network’s performance. This proposal aims to reduce block times from 12 seconds to 8 seconds, achieving a remarkable 50% increase in data handling capacity. By addressing these core issues, EIP-7781 could pave the way for more efficient Ethereum transactions.

Submitted by Ben Adams, co-founder of Illyriad Games, EIP-7781 focuses on optimizing Ethereum-based rollups to reduce latency and increase “blob” capacity. This refers to the temporary data structures that help minimize Layer 2 network fees. The objective is to manage bandwidth consumption effectively without additional blocks or blobs.

EIP-7781: Shaping Future Improvements with Slot Time Reduction

Justin Drake, a respected Ethereum researcher, strongly supports EIP-7781. He explains that reducing slot times will offer numerous benefits. According to him, this adjustment will raise the gas limit from 30 million to 40 million and increase the blob limit from 6 to 9 per block. This means decentralized exchanges, such as Uniswap v3, could operate more efficiently—up to 1.22 times more so—and potentially save $100 million yearly in CEX-DEX arbitrage. As a result, user friction would decrease with one-third shorter confirmation times and smoother peak load distribution.

Despite potential challenges, such as heightened sensitivity due to shorter slot-to-ping ratios, Drake believes that the overall efficiency gained with an 8-second slot time will maintain a healthy balance. This is crucial since execution clients often idle as blocks are being verified.

Milestone for Ethereum’s Foundation Layer

Pseudonymous developer Cygaar wholeheartedly endorses EIP-7781, describing it as a crucial milestone for improving Ethereum’s Layer 1 performance. While many developers focus on Layer 2 solutions, Cygaar asserts that this proposal will drastically enhance core functionality by allowing an increase in data blobs per block and faster block times.

If successfully adopted, EIP-7781 provides a framework for potentially even shorter slot durations in the future. Amid the ongoing conversation around scaling Ethereum, this proposal could play a pivotal role in the network’s strategic development.
