In the rapidly evolving landscape of blockchain technology, few milestones have carried as much symbolic and technical weight as Ethereum’s transition to proof-of-stake. Known as The Merge, this pivotal upgrade marked a fundamental shift in how the network operates—ushering in a new era of sustainability, scalability, and security. At the heart of this transformation lies a deeper narrative: the global collaboration that propelled Ethereum forward, with key contributions from visionaries like Feng Xiao, founder of Wanxiang Blockchain Labs.
This article explores the journey behind Ethereum’s evolution, focusing on the strategic support provided by Wanxiang Blockchain Labs, the significance of the “Shanghai Moment,” and what it means for the future of decentralized systems.
The Merge: A Turning Point for Ethereum
On September 15, 2022, Ethereum completed The Merge—a historic network upgrade that transitioned the blockchain from energy-intensive proof-of-work (PoW) to an efficient proof-of-stake (PoS) consensus mechanism. This change reduced Ethereum’s energy consumption by 99%, slashed ETH issuance by approximately 90%, and laid the groundwork for future scalability enhancements.
With this milestone achieved, attention turned to the next phase: the Shanghai upgrade. Scheduled roughly six months after The Merge, Shanghai introduced critical functionality such as staked ETH withdrawals, giving validators full control over their assets and completing the post-Merge transition.
But beyond its technical implications, “Shanghai” also carries deep historical resonance within the Ethereum community.
"The name 'Shanghai' isn’t arbitrary—it reflects a moment when East met West in the world of decentralized innovation."
Why "Shanghai"? A Legacy of Global Collaboration
The naming convention for Ethereum upgrades often draws from cities where major development milestones occurred. In 2016, Ethereum’s third developer conference (DEVCON2) was held in Shanghai, drawing nearly 90% international attendees. The event played a crucial role in spreading blockchain awareness across China and strengthening global developer ties.
Wanxiang Blockchain Labs was a founding sponsor of DEVCON2, covering all operational costs while ensuring that ticket sales and sponsorship revenues directly supported the Ethereum Foundation. This level of commitment underscored a long-standing belief in open-source collaboration and the transformative potential of decentralized technologies.

Because Ethereum follows a tradition of naming upgrades after host cities, the post-Merge activation was fittingly dubbed the “Shanghai Moment”—a tribute not only to the city but to the spirit of international cooperation it represented.
Early Connections: Building Bridges Between East and West
Feng Xiao’s engagement with Ethereum began in late 2014 during a digital currency forum hosted by Caixin magazine. The discussion attracted early blockchain pioneers, including members of what would become the core Ethereum community. Following the event, Xiao reached out to Vitalik Buterin, Ethereum’s co-founder, initiating a dialogue that would shape future collaborations.
Their first in-person meeting took place in April 2015 in Shanghai, where Buterin stayed with Eric Zhang (Shen Bo), a close associate and early supporter. Despite his growing influence, Buterin lived simply, dedicating time to learning Chinese through translated materials—an effort that symbolized his openness to cross-cultural exchange.
At a time when funding uncertainties threatened Ethereum’s development pace, Xiao stepped in with a visionary move: a $500,000 donation from Wanxiang Blockchain Labs to the Ethereum Foundation. This act alleviated financial pressure on developers and reinforced confidence in Ethereum’s long-term viability.
Fueling Innovation: The Rise of Wanxiang Blockchain Labs
Empowered by this early success, Wanxiang Blockchain Labs launched a series of initiatives to nurture blockchain innovation:
- October 2015: Hosted the first Wanxiang Blockchain Global Summit in Shanghai.
- Early 2016: Organized China’s inaugural Blockchain Hackathon, bringing together developers, entrepreneurs, and researchers.
- September 2016: Expanded into Blockchain Week, integrating DEVCON2, startup pitch events, and international summits under one umbrella.
These efforts established Shanghai as a hub for blockchain thought leadership and demonstrated China’s growing role in shaping global crypto discourse—even amid regulatory complexity.
Ethereum’s Roadmap: From Shanghai to Scalability
While the Shanghai upgrade resolved immediate concerns around staking liquidity, it also set the stage for more ambitious goals. Ethereum developers are now focused on achieving:
- 100,000 transactions per second (TPS) within three years
- Up to 10 million TPS over the next decade
These targets hinge on upcoming upgrades like danksharding, proto-danksharding, and continued layer-2 expansion via rollups. Together, they aim to make Ethereum not just sustainable, but capable of supporting mass adoption across finance, identity, gaming, and beyond.
As part of this vision, Ethereum is increasingly seen as the foundational protocol layer for Web3—a standardized stack upon which decentralized applications can securely interoperate.
Understanding the Bigger Picture: FAQs
What is the “Shanghai Upgrade”?
The Shanghai upgrade enabled withdrawals of staked ETH and introduced EIP-4895, allowing validators to access rewards and principal after The Merge. It marked the completion of Ethereum’s transition to PoS.
Why was Shanghai chosen as the name?
Ethereum names upgrades after cities significant to its development history. Shanghai hosted DEVCON2 in 2016, a landmark event co-sponsored by Wanxiang Blockchain Labs that helped globalize Ethereum’s reach.
How did Wanxiang Blockchain Labs support Ethereum?
The lab provided early financial backing—including a $500,000 donation—and hosted key events like DEVCON2 and Blockchain Week, fostering developer growth and cross-border collaboration.
👉 Explore cutting-edge tools that empower developers building on public blockchains.
Is Ethereum fully scalable today?
Not yet—but it's on track. Current layer-2 solutions already handle tens of thousands of TPS collectively. Future upgrades aim to embed high throughput directly into the base layer.
What role does proof-of-stake play in Ethereum’s future?
PoS enhances security, reduces environmental impact, and enables economic finality through slashing conditions. It forms the bedrock for all future scalability innovations.
How has China influenced global blockchain development?
Despite regulatory constraints, Chinese institutions like Wanxiang Blockchain Labs have played outsized roles in funding research, hosting international conferences, and promoting open-source contributions.
The Lasting Impact of Open Collaboration
The story of Ethereum’s “Shanghai Moment” is more than a technical upgrade—it's a testament to what happens when diverse minds come together around a shared vision. From modest beginnings in Shanghai apartments to global developer summits, the journey reflects the decentralized ethos at Ethereum’s core.
Books like "Tokens: The Future of Digital Finance", published by China Translation & Publishing House, help preserve this history and educate new generations about blockchain’s potential. As we look ahead to further upgrades—like Cancun and Prague—the principles established during the Shanghai era remain vital: transparency, inclusivity, and long-term thinking.
