Buterin Proposes Faster Ethereum Transactions

Vitalik Buterin, Ethereum's co-founder, has suggested new methods to accelerate transaction confirmation times on the Ethereum network. In a recent blog post, Buterin outlined a novel approach where each block is finalized before the next one is created, aiming to significantly enhance transaction speed and user experience.

Historically, Ethereum has lagged behind other blockchains in transaction speeds. Although transaction times have improved to 5-20 seconds following the Merge, other chains are still twice as fast. A report by CoinGecko in May 2024 revealed that Ethereum does not rank among the top 10 fastest blockchains, with Solana, SUI, and Binance Smart Chain leading the way. To address this, Buterin proposes a method called single-slot finality, which would greatly reduce the current 12.8-minute transaction finalization time under Ethereum’s Gasper consensus.

Buterin emphasized the inefficiency of the current system, stating, “Over the last couple of years, we’ve become more and more uncomfortable with the current approach. The key reasons are that (i) it’s complicated, and there are many interaction bugs between the slot-by-slot voting mechanism and the epoch-by-epoch finality mechanism, and (ii) 12.8 minutes is way too long, and nobody cares to wait that long.”

The need for improved transaction speed is critical as the market anticipates the approval of Ethereum spot exchange-traded funds (ETFs) in the US, with investors closely watching the cryptocurrency's competitive stance. Currently, Ethereum is priced at $3,389, showing a 1.24% increase over the previous 24 hours.

Buterin also advocates for using layer 2 solutions, or rollups, which process transactions faster by utilizing smaller groups of validators. These layer 2 solutions allow Ethereum’s main layer (L1) to concentrate on core functions like stability, censorship resistance, and security. The primary role of layer 2 is to enhance user experience by speeding up transactions and adapting to various needs.

However, users still demand even faster transaction speeds, prompting L2s to develop their own systems for quick confirmations. This process, akin to building an entirely new blockchain layer, adds complexity but is necessary to meet user expectations.

Another proposal from Buterin involves allowing users to pay additional fees for immediate transaction confirmations. This system, known as fee-based confirmations, would enable Ethereum proposers to guarantee transaction inclusion in the next block. If proposers fail to do so, they would incur penalties, ensuring reliability and quick confirmations.

Buterin believes these changes are feasible, but they remain conceptual at this stage. No details about implementation or timelines have been provided yet.

In summary, Buterin's proposals aim to keep Ethereum competitive as it currently trails behind other blockchains in transaction speeds. The introduction of single-slot finality and enhanced layer 2 solutions could significantly reduce waiting times and improve user experience. Additionally, fee-based confirmations offer a method for immediate transaction processing, ensuring that Ethereum remains attractive to users and investors alike.

As the market nears the potential approval of Ethereum ETFs in the US, these enhancements are crucial. Improving transaction speeds and user experience will help Ethereum maintain its position as a leading blockchain. The combination of single-slot finality, layer 2 solutions, and fee-based confirmations represents a comprehensive strategy to address the current limitations and propel Ethereum forward.

Ultimately, Buterin's vision for a faster and more efficient Ethereum highlights the ongoing efforts to evolve and adapt to the needs of the market. While these proposals are still in the idea phase, their implementation could significantly impact Ethereum's performance and competitiveness. As the crypto landscape continues to develop, such innovations will be key to maintaining and enhancing Ethereum's role in the blockchain ecosystem.
