Introduction

Preconfirmations are a mechanism that allows block proposers to commit to a block's contents before it is included in the blockchain. Follow the Ethereum Sequencing and Preconfirmations calls here.

Research and Discussion

• Based Preconfirmations - The original post introduces the concept of based preconfirmations.
• Eth Research: Preconfirmations Tag - A collection of research discussions and proposals related to preconfirmations on the Ethereum Research forum.
• Value-Capturing Based Rollups with Preconfirmations - A protocol which allows for based rollups to capture value generated from block building with preconfirmations.

Talks

ZuBerlin - 2024

• Drew, Kubi, Lorenzo - Commit-Boost - Introducing the Commit-Boost effort, including a walkthrough of the code.
• Daniel - LimeChain - Dicusses how preconfirmations interact with the L1 PBS pipeline.
• Conor - Switchboard - Introduces Preconfirmations Sauna, a credibly neutral effort to standardise preconfirmations.

Implementations

• Bolt - Bolt enables Ethereum block proposers to provide credible commitments about the contents of their blocks.
• Espresso - Espresso allows applications to sell their sequencing rights through an open marketplace.
• mev-commit - A credible commitment network used for preconfirmations & more.

Based Rollups

• KeySpace - Keyspace is a cross-chain key/value store for smart wallet keys and other configurations.
• Taiko - Taiko is an EVM-based rollup.

Related Concepts

• Proposer-Builder Separation (PBS) - A related concept that separates the roles of proposers and builders in the Ethereum consensus layer.
• MEV-Boost - A middleware that outsources block building to a network of builders, enabling proposer commitments.
