Pureth in Reth: SSZ Execution Blocks and Query Language
2026-11-04 –, Workshop 2

This EPF project implements selected Pureth components in Reth: SSZ execution objects and roots, along with a query & proof layer for execution data. We will show how these parts come together, how our implementation queries selected data and returns proofs that can be independently verified.


This talk will share what we worked on throughout the cohort while implementing the Pureth in Reth project. We will go through our work on withdrawals, receipts, transactions and execution blocks, the process and the problems we faced midway, how the two parts of the project came together and the main learnings we had while working with Reth, SSZ and the Pureth EIPs.

Hi, I'm Arsh. I've been around Ethereum for a while, working across open source and protocol infrastructure

I am fellow under the EPF Cohort 7 coming to devcon to present my project Pureth in Reth.
Apart from that i am looking forward to explore and meet core devs and have meaningful and technical discussions about future development in the ethereum protocol space.
