Awesome Based Rollups

Awesome Based Rollups

A curated list of resources, research, and implementations related to based rollups in the Ethereum ecosystem. Special thanks to Swapnil of Nethermind for starting this months ago. During aggregation we also want to thank the Spire and mteam for also working on similar types of collections.

Introduction

Based rollups the future of Ethereum. Follow the Ethereum Sequencing and Preconfirmations calls here.

Research and Discussion

Based rollups—superpowers from L1 sequencing - Justin Drake’s post formalzing the based sequencing concept
Vanilla Based Sequencing - Early exploration around a “vanilla” implementation of based rollups.
Alternate PBS: A PBS Proposal for Based Rollups - This article introduces Alternate PBS, a new PBS proposal for based rollups.
Fabric - Fabric to Accelerate Based Rollup Infrastructure & Connectivity - Propsal for a coordination and development effort to establish standards for based rollups.
Becoming Based: A Path towards Decentralised Sequencing - A proposal to work with current L2s that progresses towards based sequencing.
Understanding Based Rollups: PGA Challenges, Total Anarchy, and Potential Solutions - Paper analyzes the economics of based rollups using total anarchy as a method of sequencing blocks.
Based Rollups with Stronger Finality & Revenue Share (WIP) - Describes a version of Ethereum shared sequencing for “based rollups” that retains the benefits of vanilla based sequencing (liveness, censorship resistance, L1 security and composability etc) while offering rollups stronger finality and a share of sequencing revenue.

Transaction Flow

Transaction Submission on Based Rollups - This post explores the trade-offs between different ways to submit transactions to the rollup.

Inbox / Withdraws

Custard - Improving UX for Super TXs - Proposes a technique for enabling atomically composable super transactions on based rollups through state management.
Fast (and Slow) L2→L1 Withdrawals - Introduces a new fast path for L2 withdrawals to L1 within the same L1 slot, enabled by solvers.
Same-Slot L1→L2 Message Passing - Post introduces a protocol that enables the L2 proposer to selectively inject L1 messages emitted in the same slot directly into L2.

Composability

Generalized Synchronous Composability - Aims to sketch out a way to make it possible to do synchronous composability between L1 and all L2s in an efficient way.
The Open Intents Framework: Intents As A Public Good - Important effort that can benefit based rollup composability.
ULTRA TX - Programmable blocks: One transaction is all you need for a unified and extendable Ethereum - This post focuses on a novel mechanism to bring programmable L1 blocks and what this means for L2s and the interoperability between L1 and L2s.
Embedded Rollups, Part 1 and Part 2 - Posts exploring fast and efficient cross-chain interoperability by implementing an embedded shared-bridge rollup.

Blobs

Blob Aggregation - Step Towards More Efficient Blobs - Article explores efficiency gains for blob sharing.
Blob Sharing for Based Rollups - Introduces a protocol for based rollups to share blobs with each other so they can fill the blobs more efficiently and reduce L1 gas cost.
Blob sharing protocol - Details idea for blob sharing across various rollup stacks.
Nethermind Blob Sharing POC and Blobs Sharing Presentation on Fabric Call
Potential impact of blob sharing for rollups - Explores the impact of blob sharing by rollups.
Shared Blob Compression - Explores an implementation to help with the increasing need for chains to opt-into having their blobs aggregated and compressed with blobs from other appchains.
Will Blob Sharing Solve Dilemma for Small Rollups - This paper examines the effectiveness of blob sharing based on real-world data collected approximately six months after the implementation of EIP-4844.

Economics

Based Rollup Economics - Post that summarizes the current economic landscape of rollups, and explore based rollups economy.

Based Rollups can reward Proposers first come first serve - Articles explores how a simple FCFS system should be sufficient for Based Rollups.
Based Ticketing Rollup - Presents a “Based Ticketing Rollup” that starts from the concept of a Based rollup and adds Execution Tickets to address its weak points.
MEV for “Based Rollup” - Article exploring how MEV can work with based rollups.
