Building Together: Execution-Layer Client Ecosystem Fundraise


Ethereum’s diverse client ecosystem is at the foundation of all that we’re building together. This includes both execution-layer and consensus-layer clients, both of which are essential parts of Ethereum’s post-merge future.

Supporting execution-layer (formerly “Eth1”) clients remains one of the Ethereum Foundation’s highest priorities. These client teams have supported Ethereum’s growth over the past several years, and they will continue to provide critical infrastructure for the network post-merge, as Ethereum transitions to a Proof of Stake consensus system. Since January 2020, the EF has spent more than $10M on execution-layer client R&D. Our steadfast support will continue as these teams adapt and scale along with the broader community.

At the same time, we believe it is healthy for Ethereum clients to receive funding and support from a broader range of community stakeholders, reflecting the growth and diversification of the ecosystem.

Collaborative efforts, and specifically those dedicated to supporting teams and builders that maintain a diverse set of Ethereum clients, are a lasting and impactful way to benefit Ethereum in the long-term.

Building together

Today, we’re excited to announce that Compound Grants, Kraken, Lido, Synthetix, The Graph and Uniswap Grants are donating $250K each to support Ethereum execution-layer client teams. This project is the result of several months of work, and will supplement the significant funding provided by the Ethereum Foundation this year. This fundraise will have no impact on the EFs continued financial support for these teams.

The support of capable and leading entities from across industries will strengthen and further the innovations taking place on Ethereum.

This project represents an effort to secure Ethereum’s long-term growth, health and decentralization. Each of these elements can be exemplified by client diversity, strength of the teams themselves, and our confidence that Ethereum will continue to succeed as they succeed.

Why begin with this approach?

Part of our goal with this first round is to lessen risks that come from reliance on any single team or entity as we all work to maintain quality open source products in a diverse, decentralized, and sustainable way.

We continue to work towards more decentralized funding mechanisms for Ethereum’s public goods, and this is one more step that enables larger groups of participants to directly support client development and maintenance.

Recipients

With this goal of client diversity and the network’s success at heart, we are proud to announce the recipients of this round: Besu, Erigon, Geth, Nethermind, and Nimbus.

As a public good, Ethereum benefits from shared responsibility. This is true in terms of client diversity and the depth and width of the ecosystem’s ability to support itself.

Ethereum is a project with the potential to change and improve the very core of human, social and market interactions on a global scale. With groundbreaking applications and innovation on the network and ever-increasing adoption, the Ethereum community is pushing the boundaries of what’s technically and technologically feasible with each new day. We’re excited to take this next step to continue that growth, and ask that you join us in our effort to strengthen Ethereum by guaranteeing that Ethereum remains a diverse and sustainable project, and one that is maintained by many for a long time to come. 🚀

Merge sequence engaged 🚀

Mainnet Merge incoming

Yesterday on the Consensus Layer call, client engineers agreed on Mainnet parameters for the Merge – a Bellatrix epoch of 144896 and a Paris TTD of 58750000000000000000000 (tentative). The TTD is based on Proof-of-Work difficulty and is thus a bit hard to estimate precisely. The target date is September 15, 2022, but this estimate might have even a week of error. On this coming week’s All Core Dev call estimates will be re-checked, and the TTD will either be confirmed or a final adjustment will be made to better hit the target date.

Reminder💡: The Merge consists of a sequence of two upgrades – Bellatrix on the Consensus Layer followed by Paris on the Execution Layer.

Bellatrix upgrades the Beacon Chain to be “Merge aware”, embedding the Beacon Chain with the Merge logic as validators begin dilligently monitoring the Proof-of-Work chain to initiate the Merge transition. Bellatrix is activated at the chosen epoch.

Paris is the Merge transition itself, in which Ethereum Mainnet hot-swaps its consensus from Proof-of-Work to the Beacon Chain’s Proof-of-Stake. The Paris upgrade activates at the chosen Terminal Total Difficulty (TTD).

⚠️ All hands on deck ⚠️

Stakers, infrastructure providers, users, and community members – this is your warning. The Merge mainnet sequence is engaged. For the next ~5 weeks, stay tuned, watch for updates, remain agile, and be ready for anything. The following is the high level of dates and events expected to unfold:

  • [2022/08/18] – TTD reassessed and finalized on All Core Devs call
  • [2022/08/18 to 2022/8/22] – EL and CL teams cut Mainnet software releases
  • [2022/08/23] – Client resources, EF blog, and other community and infrastructure announcements of final parameters and releases
  • [2022/09/06 11:34:47am UTC] – Bellatrix Mainnet upgrade
    • All stakers must upgrade to EL+CL Merge-ready nodes before this time
    • All infrastructure providers, users, and community members should upgrade PoW nodes to EL+CL Merge-ready nodes before this time
  • [Estimated: 2022/9/15] – Paris Mainnet Merge transition
    • All infrastructure providers, users, and community members must upgrade to EL+CL Merge-ready nodes before this time. Plan on configuring systems at least one week in advance and ideally before Bellatrix

Between initial mainnet release announcements and the final Merge transition, users must remain diligent – monitoring client channels, the EF blog, and other public resources for any new information. Specifically, client teams might release final hardened versions of their software in this time frame and, if possible, users should upgrade.

Huge shout-out to the engineers, researchers, and community members that have worked tirelessly, putting countless hours into this. Merge sequence engaged 🚀

Sepolia Post-Merge Upgrade Announcement | Ethereum Foundation Blog

Published

on

Finalized no. 32 | Ethereum Foundation Blog


  • The Sepolia testnet will undergo a post-merge execution layer (EL) upgrade at block 1735371, expected on August 17, 2022
  • The upgrade will cause EL clients on the network to disconnect from peers which have not transitioned to proof-of-stake. It does not add additional functionality beyond this.
  • Sepolia node operators must upgrade their execution layer client prior to block 1735371.
  • A similar upgrade is expected on Goerli and the Ethereum mainnet once these networks have transitioned to proof-of-stake

Background

In order to maintain a healthy peer list, nodes on Ethereum’s execution layer will automatically disconnect peers who do not have the same upgrade sequence as them. On the Ethereum mainnet, this means checking whether a peer upgrded to Frontier Thawing at block 200,000, then Homestead at block 1,150,000, and so on all the way to the latest upgrade, Gray Glacier, which happened at block 15,050,000. EIP-2124 specifies how this is handled. In typical network upgrades, which are triggered by a block height, this happens automatically as nodes use the block height of upcomming upgrades to filter peers.

For The Merge, this was not possible because the upgrade was triggered using a total difficulty value rather than a block number. The rationale for this choice is explained in EIP-3675:

Using a pre-defined block number for the hardfork is unsafe in this context due to the PoS fork choice taking priority during the transition.

An attacker may use a minority of hash power to build a malicious chain fork that would satisfy the block height requirement. Then the first PoS block may be maliciously proposed on top of the PoW block from this adversarial fork, becoming the head and subverting the security of the transition.

To protect the network from this attack scenario, difficulty accumulated by the chain (total difficulty) is used to trigger the upgrade.

To minimize changes to the protocol during its most complex upgrade since launch, the design for The Merge excluded EIP-2124 compatibility. This means an additional upgrade must now be done to add this. It is important to note that the only change introduced as part of this upgrade is specifying a block number that nodes can use to identify peers who have gone through The Merge. No other functionality is introduced or deprecated as part of this upgrade.

Upgrade Information

Timing

This upgrade will happen on Sepolia at block 1735371, expected on August 17, 2022.

Note that a similar upgrade will be announced for Goerli and mainnet after these networks have transitioned to proof-of-stake.

Ropsten will not be upgraded since it is now considered deprecated, along with Rinkeby and Kiln. See this post for more details on their deprecation schedule.

Client Releases

Only execution layer clients need to be updated for this upgrade. Node operators can keep running their current consensus layer client release on Sepolia through the transition.

Note that client releases used for the Goerli/Prater merge all support this upgrade on Sepolia. In other words, if you already downloaded a release for the Goerli/Prater merge, you can use that same version on Sepolia for this upgrade.

Execution Layer

Upgrade Specifications

The specification for this change is tracked as part of the Paris specifications, under the FORK NEXT Upgrade section.

FAQ

As a node operator, what should I do?

You should upgrade your execution layer client to one of the versions listed above before August 16, 2022. Your consensus layer client does not need to be upgraded.

As a staker, what do I need to do?

The validator set on Sepolia is permissioned. If you are part of the current Sepolia validators, you must update your execution layer client to one of the versions listed above on August 16, 2022 at the latest.

If you are not part of the current Sepolia validator set, you do not need to do anything at this time.

Goerli/Prater and mainnet validators will need to follow the same steps when this upgrade is announced on those networks.

As an application or tooling developer, what should I do?

Nothing, unless you are also running a node. If so, please upgrade your execution layer client to one of the versions listed above before August 16, 2022.

As an Ethereum user or Ether holder, is there anything I need to do?

No. The Ethereum mainnet is not affected by this upgrade. Even when this upgrade will be applied to mainnet, there won’t be any action needed.
