Ethereum is a protocol present process vital 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 builders stopped utilizing the terminology, preferring ‘execution layer’ and ‘consensus layer’, respectively. In the present day, 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 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 community in a decentralized means and to transition to proof-of-stake. Early on, researchers labored on these efforts individually, however round 2018 they have been mixed right into a single roadmap underneath the “Ethereum 2.0” umbrella.
As a part of that roadmap, the prevailing 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 called 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 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 reminiscent of Stateless Ethereum, a paradigm that may take away the untouched state from the community to certain its progress fee.
The elevated give attention to making the proof-of-work chain long-term sustainable paired with the conclusion that the Beacon Chain could 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 functions, because the transfer to proof-of-stake might occur with none migration on their finish.
Shortly after this proposal, Danny Ryan explored how we might accomplish this by leveraging the prevailing Eth1 purchasers in his Eth1+Eth2 consumer relationship publish. This may massively cut back the event work required to ship a post-merge system and leverage current purchasers, which had been battle-tested for years on Mainnet. Across the identical time, analysis on rollups as a viable and safe solution to scale Ethereum proved promising. As an alternative of ready on a fancy, unsure scaling resolution years away, we might 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 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.
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 selection permits content material on Ethereum to be understood by the broadest viewers potential.
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 one way or the other migrate their ETH earlier than the Eth2 improve.
We hope this up to date terminology will deliver readability to eradicate 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 companies aren’t really 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 essential 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. Extra on the Ethereum upgrades.
Content material modifications
- Our ‘Eth2’ sources (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 acceptable
The rebrand was an enormous process with many content material modifications. There are possible situations we missed and enhancements nonetheless to be made. Discover one thing that wants fixing? Elevate a difficulty 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 called the Eth2 Launchpad) to replicate the terminology modifications. Please increase a difficulty or create a PR if we missed something.
Content material translations
Should you’re able to translating content material, we might use your assist! We’ve up to date this content material in English, however our 40+ further languages at the moment are outdated and nonetheless reference Eth2 terminology. Please think about getting concerned.
We’ve up to date our content material buckets to incorporate an Ethereum upgrades bucket. This can empower our a whole bunch of energetic contributors to the Translation Program to immediately goal these modifications to publish the brand new correct info throughout languages extra shortly.

A remaining observe
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 modifications will encourage others to maneuver away from the outdated Eth2 terminology. By doing so, you can be serving to to create consistency and readability throughout the ecosystem, permitting for extra correct psychological fashions and making Ethereum extra accessible.
