Supporting Ethereum’s Client Ecosystem

Supporting Ethereum's Client Ecosystem: A Crucial Step Towards Network Diversity and Decentralization

As Ethereum continues to evolve and grow, the importance of its client ecosystem cannot be overstated. With the arrival of the beacon chain in 2020, Ethereum now supports two types of clients: those focusing on the execution-layer (often referred to as eth1) and those powering the proof-of-stake consensus layer (aka eth2). Each client type serves a specific purpose and powers a different part of the Ethereum network. Recognizing the significance of both client sets to the long-term health and network diversity of Ethereum, supporting the full landscape of clients is fundamental to our work in the ecosystem.

Layer-Specific Client Support Updates

The Execution-Layer

In 2021, the Ethereum Foundation plans to allocate at least $4 million USD to execution-layer client teams. These grants, the first of which have been distributed, support the following client teams: Besu, Geth (Go Ethereum), Nethermind, Open Ethereum, and Turbo Geth. This investment is a crucial step towards sustainability and will enable these teams to continue their vital work in developing and maintaining the execution-layer clients.

The execution-layer clients are responsible for processing transactions and executing smart contracts on the Ethereum network. They are the backbone of the Ethereum ecosystem, and their stability and security are essential for the network's overall health. By supporting these teams, we are ensuring that the execution-layer clients continue to evolve and improve, providing a robust and reliable platform for developers and users.

The Consensus-Layer

In 2021, the Ethereum Foundation is allocating at least $7 million USD to consensus-layer clients. This is an increase from our funding in 2020, where about $4.5 million USD was spent on client teams. The consensus-layer clients are responsible for securing the Ethereum network through proof-of-stake consensus. They are the backbone of the Ethereum network, and their stability and security are essential for the network's overall health.

The consensus-layer clients are currently being developed and maintained by four teams: Lighthouse, Teku, Prysm, and Nimbus. These teams have made significant progress in developing and stabilizing the consensus-layer clients, and their work has enabled the beacon chain to be secured by over 3.5 million Ether, supplied by over 110,000 active validators. This feat is a testament to the dedication and expertise of these teams, and their contributions to the Ethereum ecosystem are invaluable.

Moving Forward Together

As Danny Ryan explained in his recent Finalized #23 post, "as a beacon chain staker, you need an Ethereum PoW endpoint to successfully perform all of your various duties as a validator." This means that today and after the merge, both client types are required to power the network. And because the execution-layer's familiar technology remains regardless of changes to consensus, there is no action required by dapps, developers, or users to continue using Ethereum as they always have.

In short, both client types remain necessary, and the long-term strength, health, and decentralization of Ethereum succeed as they succeed. Over the last months, we've seen new interest and innovation on Ethereum, and more is surely on the horizon. As network use increases and Ethereum's potential appears even more vast, the sustainable support of open-source software on both layers is essential, and we look forward to providing further updates on our work in this area.

Conclusion

Supporting Ethereum's client ecosystem is a crucial step towards network diversity and decentralization. By investing in the execution-layer and consensus-layer clients, we are ensuring that the Ethereum network remains robust, reliable, and secure. The785 million USD allocated to client teams in 2021 is a significant investment in the future of Ethereum, and we look forward to seeing the impact of this investment in the months and years to come.

As we move forward, it is essential that we continue to support and invest in the client ecosystem. This will enable the Ethereum network to continue to evolve and improve, providing a platform for developers and users to build and innovate. By working together, we can ensure that Ethereum remains a leader in the world of blockchain and decentralized technologies.
