Ethereum is a protocol present process important adjustments. Consumer groups are upgrading the protocol to scale to satisfy world demand whereas enhancing safety and decentralization. Past protocol improvement, a essential 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 the moment, 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.
- 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 method stays the identical
- You don’t have to 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 present proof-of-work chain (Eth1) would finally be deprecated by way of the problem bomb. Customers & functions 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.
As work started on the Beacon Chain, it turned clear that the phased Ethereum 2.0 roadmap would take a number of years to ship totally. This led to a revival of analysis initiatives on the proof-of-work chain similar to Stateless Ethereum, a paradigm that will take away the untouched state from the community to sure its development fee.
The elevated deal with making the proof-of-work chain long-term sustainable paired with the belief 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 present EVM chain as “Shard 0” of the Ethereum 2.0 system. Not solely would this expedite the transfer to proof-of-stake, however it could additionally make for a a lot smoother transition for functions, 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 present Eth1 purchasers in his Eth1+Eth2 client relationship publish. 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 similar time, research on rollups as a viable and safe strategy to scale Ethereum proved promising. As a substitute of ready on a posh, unsure scaling answer years away, we may shift the main target in direction of scaling by way of rollups as a substitute of sharded execution.

Why can’t we simply use Eth2?
One main drawback with the Eth2 branding is that it creates a damaged psychological mannequin for brand new customers of Ethereum. They intuitively assume 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.
Because the roadmap for Ethereum has developed, Ethereum 2.0 has turn out to be an inaccurate illustration of Ethereum’s roadmap. Being cautious and correct in our phrase alternative permits content material on Ethereum to be understood by the broadest viewers attainable.
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 have to someway migrate their ETH earlier than the Eth2 improve.
We hope this up to date terminology will carry readability to remove this rip-off vector and assist make the ecosystem safer.
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 should not 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 adjustments
- Our ‘Eth2’ assets (ethereum.org/en/eth2) are actually our ‘Ethereum upgrades’ part
- Particular person options are actually 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 adjustments. There are seemingly 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.
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 adjustments. Please raise an issue or create a PR if we missed anything.

A ultimate word
To many, ethereum.org is seen as a reputable supply of data maintained by our neighborhood. Understandably, many didn’t need to shift away from Eth2 terminology till ethereum.org did. We hope that our adjustments 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.
