As an analyst with a background in blockchain technology and experience in analyzing Ethereum’s development, I believe that Vitalik Buterin’s latest strategies to reduce transaction times on Ethereum are a positive step towards improving the network’s user experience. His recognition of the need for faster transactions and his proposals to implement Single-Slot Finality (SSF) and Rollup Preconfirmations demonstrate a deep understanding of the challenges faced by Ethereum users and developers.


Vitalik Buterin, the co-founder of Ethereum, has revealed plans to shorten the time it takes for transactions to be confirmed on the Ethereum blockchain.

Recognizing the importance of swift transaction processing, I emphasized the requirement for latencies in the range of “a few hundred milliseconds or even fewer” for specific use cases.

New Strategies to Reduce Transaction Time

In a blog post published on June 30, Vitalik Buterin discussed Ethereum’s advancements, mentioning that confirmations now take place within 5-20 seconds, which is on par with credit card transactions. Nevertheless, Buterin is convinced that there are opportunities for enhancement through innovative approaches.

One approach for expressing this in clear and natural language:

An effective alternative is the Rollup Preconfirmation method, where confirmation of transactions is assigned to Layer 2 protocols. These protocols, including Optimism, Arbitrum, and Base, utilize Ethereum’s security while handling a larger volume and faster processing of transactions. By delegating these tasks, Ethereum’s fundamental functions such as censorship resistance and stability can be maintained, whereas Layer 2 solutions will manage the swifter transaction confirmations.

Buterin suggested an option where users pay extra fees to prioritize their transactions for confirmation in the upcoming block. This method enhances transaction security and dependability by ensuring they’re processed promptly. It is especially advantageous for Layer 2 solutions.

Ethereum’s Competitive Landscape

Ethereum’s block generation is noticeably quicker than Bitcoin‘s 10-minute blocks, taking only 12 seconds. However, it falls short of rivals such as Solana, which boasts block times of just 0.4 seconds and has faced criticism for being overly complex.

According to Buterin, a 12-second block time works well for some use cases. Nevertheless, faster solutions such as slot-and-epoch architecture are essential for applications that demand higher speeds.

As a crypto investor, I believe we’re heading towards a future where Single-Slot Finality (SSF) and Rollup Preconfirmations coexist. By employing methods like Orbit SSF, we could lessen the burden on validators, signing per slot fewer times. This could potentially extend slot durations to 16 seconds while still aiming for a lower staking minimum of 32 ETH.
