Ethereum is a protocol present process important modifications. Consumer groups are upgrading the protocol to scale to fulfill international demand whereas enhancing safety and decentralization. Past protocol improvement, a crucial shift in Ethereum has been the motion away from ‘Eth1’ and ‘Eth2’ terminology. As of late 2021, core developers stopped using the terminology, preferring ‘execution layer’ and ‘consensus layer’, respectively. At present, as highlighted in our Q1 roadmap, ethereum.org makes the identical shift.
- Eth1 → execution layer
- Eth2 → consensus layer
- Execution layer + consensus layer = Ethereum
Let’s discover why.
Tl;dr;
- The phrases Eth1 and Eth2 (Ethereum 2.0) are being phased out
- Execution layer (Eth1) and consensus layer (Eth2) are the brand new terminologies
- The roadmap to scale Ethereum in a decentralized means stays the identical
- You don’t must do something
The place did Ethereum 2.0 come from?
Ethereum all the time had, as a part of its roadmap, plans to scale the network in a decentralized way and to transition to proof-of-stake. Early on, researchers labored on these efforts individually, however round 2018 they have been combined into a single roadmap under the “Ethereum 2.0” umbrella.
As a part of that roadmap, the prevailing proof-of-work chain (Eth1) would finally be deprecated through the problem bomb. Customers & purposes would migrate to a brand new, proof-of-stake Ethereum chain, often known as Eth2.
The article The Roadmap to Serenity by ConsenSys explains how issues stood as of early 2019.
What modified?
As work started on the Beacon Chain, it grew to become clear that the phased Ethereum 2.0 roadmap would take a number of years to ship absolutely. This led to a revival of analysis initiatives on the proof-of-work chain equivalent to Stateless Ethereum, a paradigm that will take away the untouched state from the community to sure its progress price.
The elevated deal with making the proof-of-work chain long-term sustainable paired with the conclusion that the Beacon Chain can be prepared a lot sooner than different parts of the Ethereum 2.0 roadmap led to an “Early Merge” proposal. This proposal would launch the prevailing EVM chain as “Shard 0” of the Ethereum 2.0 system. Not solely would this expedite the transfer to proof-of-stake, however it will additionally make for a a lot smoother transition for purposes, because the transfer to proof-of-stake may occur with none migration on their finish.
Shortly after this proposal, Danny Ryan explored how we may accomplish this by leveraging the prevailing Eth1 purchasers in his Eth1+Eth2 client relationship submit. This could massively cut back the event work required to ship a post-merge system and leverage present purchasers, which had been battle-tested for years on Mainnet. Across the identical time, research on rollups as a viable and safe technique to scale Ethereum proved promising. As an alternative of ready on a posh, unsure scaling resolution years away, we may shift the main target in the direction of scaling through rollups as a substitute of sharded execution.

Why can’t we simply use Eth2?
Psychological fashions
One main downside with the Eth2 branding is that it creates a damaged psychological mannequin for brand spanking new customers of Ethereum. They intuitively suppose that Eth1 comes first and Eth2 comes after. Or that Eth1 ceases to exist as soon as Eth2 exists. Neither of those is true. By eradicating Eth2 terminology, we save all future customers from navigating this complicated psychological mannequin.
Inclusivity
Because the roadmap for Ethereum has advanced, Ethereum 2.0 has grow to be an inaccurate illustration of Ethereum’s roadmap. Being cautious and correct in our phrase selection permits content material on Ethereum to be understood by the broadest viewers potential.
Rip-off prevention
Sadly, malicious actors have tried to make use of the Eth2 misnomer to rip-off customers by telling them to swap their ETH for ‘ETH2’ tokens or that they need to in some way migrate their ETH earlier than the Eth2 improve.
We hope this up to date terminology will carry readability to get rid of this rip-off vector and assist make the ecosystem safer.
Staking readability
Some staking operators have additionally represented ETH staked on the Beacon Chain with the ‘ETH2’ ticker. This creates potential confusion, provided that customers of those providers will not be truly receiving an ‘ETH2’ token. No ‘ETH2’ token exists; it merely represents their share in that particular suppliers’ stake.
How does this replace change the Ethereum roadmap?
It doesn’t! It’s vital to know that this renaming represents a change in naming solely. The options on Ethereum’s present roadmap (i.e. the merge, sharding) and future options will nonetheless occur on the identical timeline. More on the Ethereum upgrades.
Content material modifications
ethereum.org
- Our ‘Eth2’ assets (ethereum.org/en/eth2) at the moment are our ‘Ethereum upgrades’ part
- Particular person options at the moment are known as ‘upgrades’
- All pages beforehand discussing Eth2 have been up to date, with explanations included the place applicable
The rebrand was an enormous process with many content material modifications. There are probably situations we missed and enhancements nonetheless to be made. Discover one thing that wants fixing? Raise an issue or open a PR on the ethereum.org GitHub.
Staking Launchpad
Replace February 1, 2022
As a part of the nice renaming, we have additionally up to date the Ethereum Staking Launchpad (previously often known as the Eth2 Launchpad) to replicate the terminology modifications. Please raise an issue or create a PR if we missed anything.
Content material translations
If you happen to’re able to translating content material, we may use your assist! We’ve up to date this content material in English, however our 40+ extra languages at the moment are outdated and nonetheless reference Eth2 terminology. Please think about getting concerned.
We’ve up to date our content buckets to incorporate an Ethereum upgrades bucket. This can empower our tons of of energetic contributors to the Translation Program to straight goal these modifications to publish the brand new correct info throughout languages extra shortly.

A closing notice
To many, ethereum.org is seen as a reputable supply of knowledge maintained by our group. Understandably, many didn’t need to shift away from Eth2 terminology till ethereum.org did. We hope that our modifications will encourage others to maneuver away from the outdated Eth2 terminology. By doing so, you’ll be serving to to create consistency and readability throughout the ecosystem, permitting for extra correct psychological fashions and making Ethereum extra accessible.
