The first Protocol Research Call marked an important milestone for the Ethereum community. It was a unique opportunity for researchers, developers, and enthusiasts to come together in one place to talk about Ethereum's future. In this article, we'll share the highlights of that call, explain how the series started, and touch on a key topic: slot finality, comparing single slot finality (SSF) and 3-slot finality (3SF). For those interested in more details about finality, check out our earlier articles on finality.

How It All Began

The idea for these calls started when the Ethereum community noticed that important conversations were happening all over the place, on Discord, Telegram, in research papers, and on various forums. To bring these discussions together, the community launched the Protocol Research Call series. The goal was simple: create a clear, open space where early ideas could be discussed, refined, and eventually turned into concrete improvements for Ethereum. This new format encourages sharing ideas even before they’re fully formed, helping everyone understand the "why" behind each technical decision. Barnabe and Ansgar Dietrichs are two of the key figures behind the Protocol Research Call series. Here’s a brief look at their contributions and stories:

Barnabe:
Barnabe is Known for his clear communication and passion for decentralized systems, he has helped highlight the need for structured, open conversations about Ethereum’s future. His efforts in promoting these calls ensure that early stage ideas, often scattered across various channels, can be brought together into a cohesive discussion.

Ansgar:
Ansgar is a respected researcher and developer in the Ethereum ecosystem. With deep technical expertise in consensus mechanisms and network security, he co-hosted the firs call. Ansgar’s focus on tackling complex topics like slot finality (SSF vs. 3SF) and validator set dynamics has been instrumental in driving forward meaningful discussions. His ability to break down intricate technical issues makes these discussions accessible to both experts and newcomers alike.

Together, Barnabe and Ansgar recognized the value of centralizing these critical conversations, helping to bridge the gap between scattered technical debates and a unified vision for Ethereum’s roadmap.

Call Highlights

During the call, several key topics were discussed:

  • Ethereum Research Landscape: The call focused on two main areas, how Ethereum handles consensus (the way it agrees on new blocks) and how it executes transactions. This helps in understanding both the technical and practical improvements needed for the network.
  • Consensus Improvements: One big theme was how to make Ethereum faster and more secure. There was talk about scaling the consensus layer (making sure more data can be processed) and finding better ways to manage the network’s validator set—the group of participants that help secure the blockchain.
  • Layer 2 Enhancements: The discussion also touched on ways to make Ethereum more friendly for Layer 2 solutions, which help reduce costs and speed up transactions.

Slot Finality: SSF vs 3SF

A major part of the conversation was about slot finality, how quickly and securely blocks are confirmed on the network. Here’s a quick look at the two ideas:

  • Single Slot Finality (SSF):
    SSF aims to confirm blocks very quickly. While this can make transactions seem faster, it may come with risks like longer times to truly finalize a block and potential reorganization of the chain (reorg risks).

  • 3-Slot Finality (3SF):
    With 3SF, there’s an extra layer of safety. By using three slots (or time intervals), the network adds a buffer that helps secure the block before it's considered final. This method might slow things down a bit but can make the process more secure.

These discussions are part of a bigger picture on how to balance speed and security. If you're curious to dive deeper into this topic, we’ve already written about finality in detail.

The first call was just the beginning. It set the stage for regular, monthly meetings where the community can suggest topics and share ideas. This ongoing dialogue is key to making sure Ethereum continues to evolve in a way that works for everyone, from experienced developers to everyday users.
The call highlighted the need for more talks on topics like validator rotation, state management, and other technical challenges. Everyone is invited to participate in these calls, suggest ideas, and help shape Ethereum's future. Upcoming discussions will continue to explore how to make Ethereum both fast and secure, building on the ideas shared during this call.
