Vitalik Buterin, co-founder of Ethereum, has introduced new proposals to enhance the efficiency of transaction confirmation times on the Ethereum network. He emphasized that while Ethereum has seen significant improvements, there are still opportunities to further enhance the user experience.

Proposed Enhancements

In a recent blog post, Buterin highlighted the need for faster transaction confirmation times, especially for applications that require latencies in the range of hundreds of milliseconds or less. One of the proposed methods is single-slot finality (SSF), which aims to simplify the current slot and epoch architecture.

“The main challenge with SSF is that naively, it seems to imply that every single Ethereum staker would need to publish two messages every 12 seconds, which would be a lot of load for the chain to handle.” – Vitalik Buterin

Additional Proposals

Buterin also proposed “based preconfirmations,” a mechanism where users can offer additional fees for immediate transaction guarantees. This standardized protocol would allow users to ensure their transactions are included in the next block by paying extra fees. This approach is versatile and can be applied to various layer-2 solutions such as Optimism, Arbitrum, or Base.

Comparative Analysis

In contrast to Bitcoin, which has an expected block time of around 10 minutes, Ethereum’s block generation time is approximately 12 seconds. While this is faster, it still lags behind competitors like Solana, which boasts a block time of just 0.4 seconds. Buterin notes that a 12-second block time is sufficient for some applications, such as Ethereum-based domains and certain payments. However, for those requiring faster solutions, the slot-and-epoch architecture remains the only viable option.
