Ethereum 2.0, the highly anticipated upgrade set to revolutionize the blockchain network, was conspicuously absent from this year’s Ethereum Community Conference (EthCC) in Paris. As speculation swirled about its status, PegaSys protocol researcher Ben Edgington provided key insights into where things stand, dispelling doubts and offering a roadmap for what’s to come.
A Faster, Stronger, and More Scalable Ethereum
Ethereum 2.0, or Eth2, is poised to be the most significant upgrade in the network’s history. Designed to address scalability issues, reduce transaction costs, and enhance security, it will transition Ethereum from the current proof-of-work (PoW) model to a far more efficient proof-of-stake (PoS) mechanism.
Edgington, who plays a crucial role in Ethereum’s protocol development at PegaSys (part of ConsenSys), pushed back against claims that Eth2 lacks direction. Instead, he emphasized that progress, while complex, is moving at a rapid pace.
“Given the scope of what we’re building, progress is as rapid as anyone could expect,” Edgington stated. In fact, since Ethereum 2.0 underwent a “reset” in June of the previous year—abandoning earlier concepts like a hybrid PoW/PoS consensus—he believes the upgrade has been astonishingly swift.
Building a Blockchain from the Ground Up
One of the biggest challenges in delivering Ethereum 2.0 is its sheer scale. The transition isn’t just an upgrade—it’s essentially a brand-new blockchain. “Effectively, we’ve designed a brand new blockchain from the ground up in eight months or so, which is an amazing achievement,” said Edgington.
However, with a fully operational Ethereum 2.0 not expected until 2021 or beyond, critics question whether the network risks losing momentum. Some skeptics, like Ethereum core developer Lane Rettig, have even suggested that the project lacks concrete bandwidth requirements and is still in an early conceptual phase.
The Beacon Chain: Ethereum 2.0’s First Step
The foundation of Ethereum 2.0 lies in the Beacon Chain, which will manage validators—participants who stake their ETH to secure the network. According to Edgington, the goal is to have 65,000 stakers, mirroring the number of nodes currently running Ethereum.
But when will it go live? Edgington is hesitant to commit to a firm date but hinted at a possible rollout by the end of the year. “There’s still a lot of work to do,” he admitted, pointing to the need for rigorous testing, auditing, and experimentation before the Beacon Chain can function at a production-grade level.
Sharding: The Key to Ethereum’s Future
One of the most critical aspects of Ethereum 2.0 is sharding, a solution designed to dramatically improve transaction processing. By breaking the network into smaller shards, Ethereum can handle thousands of transactions simultaneously, compared to the current network’s bottlenecked structure.
“Sharding is really the administrative layer of the whole system—the foundation, the anchor,” Edgington explained. Though Ethereum co-founder Vitalik Buterin was absent from EthCC, he has been working intensively on sharding solutions. The main hurdle? Peer-to-peer networking. “We’re breaking new ground here,” Edgington said, acknowledging that while the research is solid, the engineering challenges remain.
The Final Stage: Making Ethereum 2.0 Useful
While the Beacon Chain and sharding are essential components of Ethereum 2.0, they won’t make the network fully functional on their own. The final phase—where Ethereum can execute transactions and support applications—is still under research.
“There’s still a fair amount of work to be done for phase two,” Edgington admitted. However, he remains confident that Ethereum 2.0 will stay on track despite concerns about delays. “With every large-scale ambitious project, there’s always a risk of not delivering, but we’re very much on the timelines that were anticipated.”
What Comes Next? Ethereum 1.x as a Bridge
As Ethereum 2.0 continues to develop, interim upgrades—collectively known as Ethereum 1.x—will help bridge the gap. The goal is to introduce smaller, more frequent updates to improve network efficiency while the full-scale Ethereum 2.0 upgrade is still in progress.
While the term “hard fork” often carries negative connotations, Edgington prefers a more optimistic outlook. The Ethereum network, he believes, is evolving rather than fragmenting. And as the pieces of Ethereum 2.0 start to take shape, the next few years could see the blockchain finally achieve the speed, scalability, and security its community has long envisioned.
