Great renaming: what happened to Eth2?


Ethereum is a protocol that is undergoing major changes. Client teams are upgrading the protocol to scale to meet global needs while improving security and decentralization. Aside from protocol development, a key shift for Ethereum is moving away from the terms “Eth1” and “Eth2”. Core developers stop using the term by the end of 2021, prefer “execution layer” and “consensus layer” respectively.Today, as Highlighted in our Q1 roadmap, ethereum.org Do the same transformation.

  • Eth1 → Execution Layer
  • Eth2 → Consensus Layer
  • Execution layer + consensus layer = Ethereum

Let’s explore why.

Tl;PhD;

  • The terms Eth1 and Eth2 (Ethereum 2.0) are being phased out
  • Execution layer (Eth1) and consensus layer (Eth2) are new terms
  • The roadmap for scaling Ethereum in a decentralized manner remains the same
  • you don’t need to do anything

Where did Ethereum 2.0 come from?

As part of its roadmap, Ethereum always has, Plans to expand the network in a decentralized manner and Transition to Proof of Stake. Early on, researchers worked on these separately, but around 2018 Consolidated into a single roadmap under the umbrella of ‘Ethereum 2.0’.

As part of this roadmap, the existing proof-of-work chain (Eth1) will eventually be deprecated via a difficulty bomb. Users and applications will migrate to the new proof-of-stake Ethereum chain, called Eth2.

article Roadmap to Serenity The authors of ConsenSys explain the situation as of early 2019.

What has changed?

As work begins Beacon Chain, it is clear that the phased Ethereum 2.0 roadmap will take several years to fully deliver. This has led to a resurgence of research initiatives on proof-of-work chains, such as stateless Ethereum, a paradigm that would remove untouched state from the network to limit its growth rate.

The growing focus on making proof-of-work chains sustainable in the long term, while realizing that the beacon chain will be ready sooner than other components of the Ethereum 2.0 roadmap, has led to “Early Merger” Proposall. This proposal will launch the existing EVM chain as “Shard 0” of the Ethereum 2.0 system. Not only will this speed up the move to proof-of-stake, but it will also make the transition for applications smoother, as the move to proof-of-stake could happen without any migration.

Shortly after making this proposal, Danny Ryan explored how we could achieve this by leveraging his existing Eth1 client. Eth1+Eth2 client relationship postal. This will significantly reduce the development effort required to deliver the combined system and leverage existing customers who have been battle-tested on mainnet for years. around the same time, Pooled Studies As a viable and secure way to scale Ethereum, it is proving promising. Instead of waiting years for complex, non-deterministic scaling solutions, we can shift our focus to scaling through aggregation rather than sharded execution.

Why can’t we just use Eth2?

mental model

A major problem with the Eth2 brand is that it creates a broken mental model for new Ethereum users. They intuitively think that Eth1 is in front and Eth2 is behind. Or once Eth2 exists, Eth1 no longer exists. None of this is true. By removing the Eth2 terminology, we can avoid all future users navigating this confusing mental model.

tolerance

As the Ethereum roadmap has evolved, Ethereum 2.0 has become an inaccurate representation of the Ethereum roadmap. Careful and accurate choice of words allows the broadest audience to understand what is on Ethereum.

Fraud Prevention

Unfortunately, malicious actors are trying to use the misnomer for Eth2 to trick users into telling them they are exchanging ETH for “ETH2” tokens, or that they have to “migrate” their ETH before the Eth2 upgrade.

We hope that this updated term will clear this scam and help make the ecosystem more secure.

Staking clarity

Some staking operators also use the “ETH2” code to represent ETH staked on the beacon chain. This creates potential confusion given that users of these services do not actually receive “ETH2” tokens. There is no “ETH2” token; it simply represents their share of the stake in that particular provider.

How does this update change the Ethereum roadmap?

It doesn’t! It’s important to understand that this renaming represents only a naming change.Features on Ethereum’s current roadmap (i.e. merge, Fragmentation) and future features will still happen on the same timeline. More about the Ethereum upgrade.

Content changes

  • Our “Eth2” resource (ethereum.org/en/eth2) is now our “Ethereum Upgrade” section
  • Individual features are now called “upgrades”
  • All previous pages discussing Eth2 have been updated with explanations added where appropriate

Rebranding is a daunting task with many changes to the content. We may have missed some instances, but there is still room for improvement. Notice something that needs fixing? File an issue or open a PR on the ethereum.org GitHub.

Content translation

If you have the ability to translate content, we can use your help! We’ve updated this content in English, but our 40+ other languages ​​are now out of date and still refer to Eth2 terminology. Please consider participating.

we updated our Content bucket Includes an Ethereum upgrade bucket. This will allow hundreds of active contributors to our translation program to directly target these changes to publish new and accurate information across languages ​​faster.

the last point

For many, ethereum.org is seen as a reliable source of information maintained by our community. Understandably, many don’t want to drop the Eth2 term until ethereum.org does. We hope our changes will encourage others to move away from the outdated Eth2 terminology. By doing so, you will help create consistency and clarity across the ecosystem, allowing for more accurate mental models and making Ethereum more accessible.
