Ethereum is a protocol present process vital modifications. Consumer groups are upgrading the protocol to scale to satisfy world demand whereas enhancing safety and decentralization. Past protocol improvement, a vital 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. At this time, 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 method stays the identical
- You don’t have to do something
The place did Ethereum 2.0 come from?
Ethereum at all times had, as a part of its roadmap, plans to scale the community in a decentralized method and to transition to proof-of-stake. Early on, researchers labored on these efforts individually, however round 2018 they had been mixed right into a single roadmap beneath the “Ethereum 2.0” umbrella.
As a part of that roadmap, the prevailing proof-of-work chain (Eth1) would ultimately be deprecated through the issue bomb. Customers & purposes 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.
What modified?
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 absolutely. This led to a revival of analysis initiatives on the proof-of-work chain equivalent to Stateless Ethereum, a paradigm that may take away the untouched state from the community to sure its progress charge.
The elevated concentrate on 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 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 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 shoppers in his Eth1+Eth2 shopper relationship publish. This could massively cut back the event work required to ship a post-merge system and leverage current shoppers, which had been battle-tested for years on Mainnet. Across the similar time, analysis on rollups as a viable and safe method to scale Ethereum proved promising. As a substitute of ready on a posh, unsure scaling resolution years away, we might shift the main target in direction of scaling through rollups as an alternative of sharded execution.

Why can’t we simply use Eth2?
Psychological fashions
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.
Inclusivity
Because the roadmap for Ethereum has developed, Ethereum 2.0 has develop into 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 attainable.
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 someway migrate their ETH earlier than the Eth2 improve.
We hope this up to date terminology will convey readability to remove 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, on condition that customers of those companies will not be 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 grasp 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
ethereum.org
- 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 applicable
The rebrand was a large job with many content material modifications. There are possible cases we missed and enhancements nonetheless to be made. Discover one thing that wants fixing? Increase a difficulty or open a PR on the ethereum.org GitHub.
Staking Launchpad
Replace February 1, 2022
As a part of the good renaming, we have additionally up to date the Ethereum Staking Launchpad (previously often called the Eth2 Launchpad) to replicate the terminology modifications. Please elevate a difficulty or create a PR if we missed something.
Content material translations
If you happen to’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 lot of energetic contributors to the Translation Program to straight goal these modifications to publish the brand new correct info throughout languages extra rapidly.
Excited by serving to to translate ethereum.org or the Ethereum Staking Launchpad? Try our translation program.
A ultimate be aware
To many, ethereum.org is seen as a reputable supply of data maintained by our neighborhood. Understandably, many didn’t wish 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.
