Ethereum is a framework experiencing substantial transformations. Client groups are enhancing the framework to expand and satisfy global needs while boosting safety and decentralization. Beyond framework advancements, a significant transition in Ethereum has been the escape from \u2018Eth1\u2019 and \u2018Eth2\u2019 nomenclature.\u00a0Since late 2021, principal developers have ceased using this terminology<\/a>, opting for \u2018execution layer\u2019 and \u2018consensus layer\u2019, respectively. Today, as\u00a0noted in our Q1 roadmap<\/a>,\u00a0ethereum.org<\/a>\u00a0is adopting the same transition.<\/p>\n <\/p>\n <\/p>\n Let\u2019s investigate the reasons why.<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Ethereum has always included, within its roadmap,\u00a0intentions to increase the network\u2019s capacity in a decentralized manner<\/a>\u00a0and to\u00a0shift to proof-of-stake<\/a>. Initially, researchers tackled these endeavors separately, but by around 2018, they were\u00a0integrated into a unified roadmap under the \u201cEthereum 2.0\u201d banner<\/a>.<\/p>\n <\/p>\n According to that roadmap, the current proof-of-work chain (Eth1) would ultimately be retired through the difficulty bomb. Users & applications would transition to a new proof-of-stake Ethereum chain, dubbed Eth2.<\/p>\n <\/p>\n The piece The Roadmap to Serenity<\/a> from ConsenSys elaborates on the state of affairs as of early 2019.<\/p>\n <\/p>\n <\/p>\n As efforts commenced on the\u00a0Beacon Chain<\/a>, it became apparent that the phased Ethereum 2.0 roadmap would require several years for full implementation. This resulted in a resurgence of research initiatives on the proof-of-work chain, like Stateless Ethereum, a concept designed to eliminate the unstated state from the network to regulate its growth rate.<\/p>\n <\/p>\n The heightened focus on rendering the proof-of-work chain sustainably long-term, paired with the understanding that the Beacon Chain would be operational significantly earlier than additional components of the Ethereum 2.0 roadmap, prompted an\u00a0“Early Merge” proposal<\/a>. This suggestion proposed launching the existing EVM chain as “Shard 0” of the Ethereum 2.0 structure. This would not only expedite the transition to proof-of-stake but also facilitate a considerably smoother shift for applications, as the transition could occur without any migration on their side.<\/p>\n <\/p>\n Shortly following this proposal, Danny Ryan examined how this could be achieved by utilizing the current Eth1 clients in his\u00a0Eth1+Eth2 client relationship<\/a>\u00a0post. This would significantly lower the development efforts needed to deliver a post-merge system and make use of existing clients that had been rigorously tested for years on Mainnet. Around the same time,\u00a0research on rollups<\/a>\u00a0as a credible and secure method to scale Ethereum showed promise. Instead of waiting for a complex and uncertain scaling solution years ahead, we could redirect our emphasis towards scaling through rollups rather than sharded execution.<\/p>\n <\/p>\n Want to delve deeper? View Danny Ryan\u2019s \u201cEth1 + Eth2 = Ethereum\u201d ETHGlobal presentation<\/a>.<\/em><\/p>\n <\/p>\n <\/p>\n <\/p>\n A significant issue with the Eth2 branding is that it establishes a misleading mental framework for new Ethereum users. They instinctively believe that Eth1 precedes Eth2, or that Eth1 ceases to exist post-Eth2. Neither of these assertions holds true. By discarding the Eth2 terminology, we protect all future users from grappling with this perplexing mental model.<\/p>\n <\/p>\n <\/p>\n As the blueprint for Ethereum has progressed, Ethereum 2.0 has evolved into an inaccurate depiction of Ethereum’s roadmap. Exercising caution and precision in word choice enables content regarding Ethereum to be comprehended by the widest audience possible.<\/p>\n <\/p>\n <\/p>\n Regrettably, malicious entities have exploited the confusion surrounding Eth2 to deceive users, urging them to exchange their ETH for \u2018ETH2\u2019 tokens or alleging that they must transfer their ETH before the Eth2 advancement.<\/p>\n <\/p>\n We hope this revised terminology will clarify matters and help eliminate this scam opportunity, contributing to a safer ecosystem.<\/p>\n <\/p>\n <\/p>\n Certain staking operators have also labeled ETH staked on the Beacon Chain with the \u2018ETH2\u2019 ticker. This creates confusion, as users of these services are not actually receiving an \u2018ETH2\u2019 token. No \u2018ETH2\u2019 token exists; it simply indicates their portion in that particular provider’s stake.<\/p>\n <\/p>\n <\/p>\n It does not! It is crucial to recognize that this renaming signifies a change in title only. The elements on Ethereum\u2019s existing roadmap (i.e. the merge<\/a>, sharding<\/a>) along with future elements will continue to occur on the identical timeline. More regarding the Ethereum upgrades<\/a>.<\/p>\n <\/p>\n \n <\/p>\n <\/p>\n <\/p>\n <\/p>\n The rebranding process was an extensive endeavor resulting in many alterations to the content.
