ephema labs
Ephema is a research group focused on mechanism design and incentive systems for Ethereum's scaling and data availability challenges. Their flagship protocol, BlobFusion, enables multiple users to share a single blob, reducing costs and improving blobspace utilization. The group also publishes research on topics like Execution Tickets, proposer-builder separation, and MEV redistribution.

Problem
Ethereum's blobspace, introduced for layer-2 data availability, is often inefficiently used because individual blobs are posted with significant unused capacity, leading to overpayment. This problem is exacerbated as demand for blobspace grows, and current mechanisms do not support sharing blobs between multiple users, forcing L2s to wait and batch transactions, which degrades finality and user experience.
Solution
Ephema is a research group that designs and implements novel mechanism and incentive systems to address these inefficiencies. Their flagship solution, BlobFusion, is a protocol that enables multiple users to share a single blob, reducing costs and improving data availability. The protocol works by accepting bids and signed data from users, then fusing them into an optimal blob that is submitted to the Ethereum network (currently Sepolia) when the sum of bids exceeds the estimated cost. This approach makes blob posting cheaper and more efficient. Beyond BlobFusion, the group conducts theoretical analysis and simulations on related topics like Execution Tickets, proposer-builder separation, shared sequencing, and MEV redistribution, publishing research accessible to the broader Ethereum community.
Target Audience
Primary users are Ethereum layer-2 teams, blockchain researchers, and protocol developers seeking to optimize data availability, reduce transaction costs, and understand incentive mechanisms. The tools and research are also relevant for validators and MEV-related actors looking to adapt to evolving protocol designs.
