Geemo's Update #1

General Thoughts

I will be focusing my efforts around light clients, because they are integral to trustless access to data on ethereum. To understand how to contribute meanfully to light client development, I first set out to learn the current state of affairs. I have been reading Ben Edgington's wonderful book Upgrading Ethereum.

Light Client Development Today

The Altair Spec outlines the p2p interface for full nodes and light clients to interact. https://github.com/ethereum/consensus-specs/tree/dev/specs/altair/light-client

Client teams have varied in their progress towards implementing the spec.

Other projects have focused exclusively on the "client" side:

Project Description

Implement a minimal light client in rust and help implement the light server spec for lighthouse. That being said, if someone thinks I could help elsewhere I am open to suggestions.

Closing Remarks

I am looking forward to working during this program. I have a lot of time to work at the moment, so I'm excited to contribute to this community that I've admired from afar for years.

EPF 4 Final Update

This project sought to increase block proposer rewards for Lighthouse users. The project proposal lives here: Lighthouse Attestation Packing.

EPF Update #10

This update covers the process toward merging the optimality preserving atttestation aggregation process.

EPF Update 9

This update will cover the current state of the new block packing methods for Lighthouse. With the assistance of Michael Sproul we have an optimality preserving aggregation strategy implemented. We are currently testing and optimizing it’s performance. This comes as a pretty significant change to the block packing logic so we must ensure that everything functions correctly with good performance. Michael set an initial performance goal as attestation packing taking <50ms.

EPF Update 8

In the past week I tested and optimised the decomposition approach that I described in my previous update. The resulting algorithm foes not perform as well as I would have hoped. That being said it is faster than the base MIP solution in some cases, but it’s not a significant difference. Additionally I’ve tested the aggregation branch and resolved some outstanding issues on it. In the next week I’d like to get the aggregation branch merged or at least looked at by Michael Sproul. It still does not perform as well as the greedy aggregation approach so it certainly isn’t worth merging as is, but I think this could be solved.
