Ethereum is a protocol present process important modifications. Shopper groups are upgrading the protocol to scale to fulfill international demand whereas enhancing safety and decentralization. Past protocol growth, a essential 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 method stays the identical
- You don’t must 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 have 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 by way of the issue bomb. Customers & purposes would migrate to a brand new, proof-of-stake Ethereum chain, referred to 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 absolutely. This led to a revival of analysis initiatives on the proof-of-work chain reminiscent of Stateless Ethereum, a paradigm that will take away the untouched state from the community to sure its development charge.
The elevated give attention to 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 might 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 purchasers in his Eth1+Eth2 shopper relationship publish. This is able to massively scale 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 similar time, analysis on rollups as a viable and safe approach to scale Ethereum proved promising. As a substitute of ready on a fancy, unsure scaling answer years away, we might shift the main focus in direction of scaling by way of rollups as a substitute of sharded execution.

Why can’t we simply use Eth2?
One main downside with the Eth2 branding is that it creates a damaged psychological mannequin for brand spanking 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 grow 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 doable.
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 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 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 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’ 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

A closing be aware
To many, ethereum.org is seen as a reputable supply of knowledge maintained by our group. 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.
