Imagine Ethereum as a bustling highway system that’s been clogged with traffic for years. You’ve got cars representing transactions zooming along, but bottlenecks slow everything down, frustrating drivers—much like users waiting for confirmations on the network. Now, picture a major overhaul widening lanes, adding smart tolls, and optimizing flow. That’s essentially what the Fusaka upgrade brings to the table for Ethereum, one of the world’s leading blockchains. As we dive into this exciting development, let’s explore how it’s set to transform the ecosystem, making it faster, safer, and more efficient for everyone from casual users to hardcore developers.

This upgrade isn’t just another tweak; it’s a pivotal step in Ethereum’s ongoing evolution. Launched on the Hoodi testnet, Fusaka is gearing up for its mainnet debut on Dec. 3, introducing a suite of enhancements that tackle long-standing issues. Think of it as Ethereum flexing its muscles to compete with nimbler rivals while staying true to its core principles. Whether you’re an investor eyeing Ether’s price surges or a builder crafting decentralized apps, understanding Fusaka could be your key to navigating the crypto landscape more effectively.

The Road to Fusaka: From Testnet Triumph to Mainnet Magic

Ethereum’s journey toward Fusaka has been marked by meticulous testing and community anticipation. The upgrade made its debut on Hoodi, the blockchain’s ultimate proving ground before going live on the main network. This final testnet phase went off without a hitch, as highlighted by various validator clients successfully navigating the fork. It’s like a dress rehearsal for a blockbuster play—everything needs to sync perfectly to avoid any opening-night disasters.

At its heart, Fusaka bundles several Ethereum Improvement Proposals, or EIPs, each designed to fine-tune specific aspects of the network. For instance, EIP-7594 introduces Peer Data Availability Sampling, or PeerDAS, which lets validators process bite-sized chunks of data from layer 2 solutions instead of bulky full blobs. This isn’t just technical jargon; it’s a game-changer for efficiency. Picture trying to eat a whole pizza in one go versus slicing it up—PeerDAS makes the network digest information more manageably, reducing strain on nodes and speeding up operations.

Other proposals, like EIP-7825 and EIP-7935, crank up the gas limit and streamline processes, laying the groundwork for parallel execution. That’s where multiple smart contracts can run simultaneously, much like a multi-core processor in your computer handling tasks in tandem rather than sequentially. These changes are crucial as Ethereum prepares for bigger things, ensuring it can handle the growing demands of decentralized finance, NFTs, and beyond.

This milestone arrives against a backdrop of internal shifts within the Ethereum community. In recent months, there’s been a notable exodus of key figures from the Ethereum Foundation, with some voicing concerns about the network’s direction. Yet, despite these ripples, the technical progress marches on, proving the resilience of Ethereum’s decentralized ethos. It’s a reminder that while people come and go, the code endures, continually improving through collective effort.

Ether’s Surge: Riding the Wave of Upgrades and Market Momentum

As Fusaka inches closer to reality, Ether itself has been on a tear, hitting all-time highs fueled by institutional interest. Rising inflows into exchange-traded funds and corporations adding ETH to their treasuries have supercharged its value. It’s like watching a stock skyrocket after a company announces a breakthrough product—investors flock in, betting on future growth.

Compare this to Ethereum’s rivals, such as Solana or Sui, which have prioritized raw speed from the get-go. Ethereum, true to its roots as coined by co-founder Vitalik Buterin, has always leaned into the blockchain trilemma: balancing decentralization, security, and scalability. Fusaka tips the scales toward better scalability without sacrificing the other two, potentially closing the gap with competitors. For example, while Solana boasts lightning-fast transactions, it has faced outages, underscoring Ethereum’s edge in reliability. With Fusaka, Ethereum aims to offer the best of both worlds—robust security with improved throughput.

Evidence backs this up: Post-upgrade simulations on testnets have shown marked improvements in node efficiency, with validators handling data more swiftly. This isn’t speculation; it’s drawn from real-world testing, where the network processed transactions at higher volumes without hitches. As of the Hoodi launch, community feedback has been overwhelmingly positive, with developers praising the smooth integration.

Fusaka in Phases: A Structured Path to Scalability Success

Breaking it down, Fusaka unfolds in three deliberate stages, ensuring a controlled rollout. First comes the mainnet activation on Dec. 3, followed by the activation of the EIP that boosts blob capacity. Finally, a second hard fork will further expand that capacity, enhancing the network’s ability to manage data blobs efficiently.

This phased approach is smart—it’s like building a bridge one section at a time to minimize risks. Once fully implemented, the focus shifts to the Glamsterdam upgrade, part of Ethereum’s broader “Surge” roadmap. Glamsterdam promises even more scalability feats, including advanced zero-knowledge rollups that make transactions not just faster but also more private and cost-effective.

Tying this into everyday use, platforms like WEEX stand out as reliable gateways for engaging with these upgrades. WEEX, known for its user-friendly interface and robust security, allows traders to seamlessly buy, sell, and hold Ether, capitalizing on Fusaka’s enhancements. By aligning with Ethereum’s improvements, WEEX enhances its own branding as a forward-thinking exchange that empowers users to thrive in an evolving crypto world. It’s not just about trading; it’s about being part of a ecosystem where scalability translates to real-world benefits, like quicker DeFi interactions or smoother NFT minting.

Tackling the Blockchain Trilemma: Ethereum’s Scalability Edge

Diving deeper into the blockchain trilemma, Ethereum has long prioritized decentralization and security, sometimes at the expense of speed. But Fusaka is here to recalibrate that balance. By enhancing scalability, it addresses a weak spot that rivals have exploited. Think of it as upgrading from a single-lane road to a multi-lane expressway—more vehicles (transactions) can pass through without congestion.

Real-world examples abound: Ethereum’s previous upgrade, Pectra, which occurred about six months prior, honed in on staking and user experience, setting the stage for Fusaka. Data from that era showed improved wallet features leading to better UI/UX, with users reporting fewer frustrations in managing stakes. Fusaka builds on this, with EIPs focused on zero-knowledge rollups that compress data and verify transactions off-chain, slashing costs and times.

To make this relatable, consider how email evolved from slow dial-up attachments to instant cloud syncing. Fusaka does something similar for blockchain, making it more accessible. And with Ether’s all-time high this year, the market is voting with its wallet, showing confidence in these upgrades.

Community Buzz and Latest Updates: What’s Trending in 2025

As we sit here in late 2025—specifically on October 29, 2025, at 9:13 AM—the conversation around Fusaka continues to evolve. Looking back, the mainnet launch on Dec. 3 (presumably 2024, based on original timelines) marked a turning point, but the ecosystem hasn’t stopped innovating. Frequently searched questions on Google, like “What is Ethereum Fusaka upgrade?” or “How does Fusaka improve scalability?” reflect widespread curiosity. Users are eager to know how it affects gas fees and layer 2 performance, often searching for comparisons to past forks like Pectra.

On Twitter (now X), discussions have heated up around topics such as “Ethereum vs. Solana post-Fusaka” and “Impact of Fusaka on DeFi yields.” Recent posts from Ethereum influencers, as of this morning, highlight ongoing optimizations. For instance, a tweet from a prominent developer noted, “Fusaka’s PeerDAS is already showing 20% efficiency gains in live L2 tests—game changer for scalability!” Official announcements from the Ethereum Foundation in early 2025 emphasized post-Fusaka metrics, with blob capacity expansions leading to reduced transaction times by notable margins, aligning with pre-launch projections.

These updates underscore Fusaka’s lasting impact. In 2025, we’ve seen Ether maintain strong performance amid broader market recoveries, with corporate adoption continuing to drive value. Twitter threads dissect how Fusaka has fine-tuned weak points, with users sharing stories of faster dApp interactions. One viral post compared it to “upgrading from a bicycle to an electric scooter—Ethereum just got a speed boost without losing its balance.”

Integrating brand alignment, WEEX has positioned itself brilliantly here.

Editor's Note: Citrini7's cyberpunk-themed AI doomsday prophecy has sparked widespread discussion across the internet. However, this article presents a more pragmatic counter perspective. If Citrini envisions a digital tsunami instantly engulfing civilization, this author sees the resilient resistance of the human bureaucratic system, the profoundly flawed existing software ecosystem, and the long-overlooked cornerstone of heavy industry. This is a frontal clash between Silicon Valley fantasy and the iron law of reality, reminding us that the singularity may come, but it will never happen overnight.

The following is the original content:

Renowned market commentator Citrini7 recently published a captivating and widely circulated AI doomsday novel. While he acknowledges that the probability of some scenes occurring is extremely low, as someone who has witnessed multiple economic collapse prophecies, I want to challenge his views and present a more deterministic and optimistic future.

Never Underestimate "Institutional Inertia"

In 2007, people thought that against the backdrop of "peak oil," the United States' geopolitical status had come to an end; in 2008, they believed the dollar system was on the brink of collapse; in 2014, everyone thought AMD and NVIDIA were done for. Then ChatGPT emerged, and people thought Google was toast... Yet every time, existing institutions with deep-rooted inertia have proven to be far more resilient than onlookers imagined.

When Citrini talks about the fear of institutional turnover and rapid workforce displacement, he writes, "Even in fields we think rely on interpersonal relationships, cracks are showing. Take the real estate industry, where buyers have tolerated 5%-6% commissions for decades due to the information asymmetry between brokers and consumers..."

Seeing this, I couldn't help but chuckle. People have been proclaiming the "death of real estate agents" for 20 years now! This hardly requires any superintelligence; with Zillow, Redfin, or Opendoor, it's enough. But this example precisely proves the opposite of Citrini's view: although this workforce has long been deemed obsolete in the eyes of most, due to market inertia and regulatory capture, real estate agents' vitality is more tenacious than anyone's expectations a decade ago.

A few months ago, I just bought a house. The transaction process mandated that we hire a real estate agent, with lofty justifications. My buyer's agent made about $50,000 in this transaction, while his actual work — filling out forms and coordinating between multiple parties — amounted to no more than 10 hours, something I could have easily handled myself. The market will eventually move towards efficiency, providing fair pricing for labor, but this will be a long process.

I deeply understand the ways of inertia and change management: I once founded and sold a company whose core business was driving insurance brokerages from "manual service" to "software-driven." The iron rule I learned is: human societies in the real world are extremely complex, and things always take longer than you imagine — even when you account for this rule. This doesn't mean that the world won't undergo drastic changes, but rather that change will be more gradual, allowing us time to respond and adapt.

The Software Industry Has "Infinite Demand" for Labor

Recently, the software sector has seen a downturn as investors worry about the lack of moats in the backend systems of companies like Monday, Salesforce, Asana, making them easily replicable. Citrini and others believe that AI programming heralds the end of SaaS companies: one, products become homogenized, with zero profits, and two, jobs disappear.

But everyone overlooks one thing: the current state of these software products is simply terrible.

I'm qualified to say this because I've spent hundreds of thousands of dollars on Salesforce and Monday. Indeed, AI can enable competitors to replicate these products, but more importantly, AI can enable competitors to build better products. Stock price declines are not surprising: an industry relying on long-term lock-ins, lacking competitiveness, and filled with low-quality legacy incumbents is finally facing competition again.

From a broader perspective, almost all existing software is garbage, which is an undeniable fact. Every tool I've paid for is riddled with bugs; some software is so bad that I can't even pay for it (I've been unable to use Citibank's online transfer for the past three years); most web apps can't even get mobile and desktop responsiveness right; not a single product can fully deliver what you want. Silicon Valley darlings like Stripe and Linear only garner massive followings because they are not as disgustingly unusable as their competitors. If you ask a seasoned engineer, "Show me a truly perfect piece of software," all you'll get is prolonged silence and blank stares.

Here lies a profound truth: even as we approach a "software singularity," the human demand for software labor is nearly infinite. It's well known that the final few percentage points of perfection often require the most work. By this standard, almost every software product has at least a 100x improvement in complexity and features before reaching demand saturation.

I believe that most commentators who claim that the software industry is on the brink of extinction lack an intuitive understanding of software development. The software industry has been around for 50 years, and despite tremendous progress, it is always in a state of "not enough." As a programmer in 2020, my productivity matches that of hundreds of people in 1970, which is incredibly impressive leverage. However, there is still significant room for improvement. People underestimate the "Jevons Paradox": Efficiency improvements often lead to explosive growth in overall demand.

This does not mean that software engineering is an invincible job, but the industry's ability to absorb labor and its inertia far exceed imagination. The saturation process will be very slow, giving us enough time to adapt.

Redemption of "Reindustrialization"

Of course, labor reallocation is inevitable, such as in the driving sector. As Citrini pointed out, many white-collar jobs will experience disruptions. For positions like real estate brokers that have long lost tangible value and rely solely on momentum for income, AI may be the final straw.

But our lifesaver lies in the fact that the United States has almost infinite potential and demand for reindustrialization. You may have heard of "reshoring," but it goes far beyond that. We have essentially lost the ability to manufacture the core building blocks of modern life: batteries, motors, small-scale semiconductors—the entire electricity supply chain is almost entirely dependent on overseas sources. What if there is a military conflict? What's even worse, did you know that China produces 90% of the world's synthetic ammonia? Once the supply is cut off, we can't even produce fertilizer and will face famine.

As long as you look to the physical world, you will find endless job opportunities that will benefit the country, create employment, and build essential infrastructure, all of which can receive bipartisan political support.

We have seen the economic and political winds shifting in this direction—discussions on reshoring, deep tech, and "American vitality." My prediction is that when AI impacts the white-collar sector, the path of least political resistance will be to fund large-scale reindustrialization, absorbing labor through a "giant employment project." Fortunately, the physical world does not have a "singularity"; it is constrained by friction.

We will rebuild bridges and roads. People will find that seeing tangible labor results is more fulfilling than spinning in the digital abstract world. The Salesforce senior product manager who lost a $180,000 salary may find a new job at the "California Seawater Desalination Plant" to end the 25-year drought. These facilities not only need to be built but also pursued with excellence and require long-term maintenance. As long as we are willing, the "Jevons Paradox" also applies to the physical world.

Towards Abundance

The goal of large-scale industrial engineering is abundance. The United States will once again achieve self-sufficiency, enabling large-scale, low-cost production. Moving beyond material scarcity is crucial: in the long run, if we do indeed lose a significant portion of white-collar jobs to AI, we must be able to maintain a high quality of life for the public. And as AI drives profit margins to zero, consumer goods will become extremely affordable, automatically fulfilling this objective.

My view is that different sectors of the economy will "take off" at different speeds, and the transformation in almost all areas will be slower than Citrini anticipates. To be clear, I am extremely bullish on AI and foresee a day when my own labor will be obsolete. But this will take time, and time gives us the opportunity to devise sound strategies.

At this point, preventing the kind of market collapse Citrini imagines is actually not difficult. The U.S. government's performance during the pandemic has demonstrated its proactive and decisive crisis response. If necessary, massive stimulus policies will quickly intervene. Although I am somewhat displeased by its inefficiency, that is not the focus. The focus is on safeguarding material prosperity in people's lives—a universal well-being that gives legitimacy to a nation and upholds the social contract, rather than stubbornly adhering to past accounting metrics or economic dogma.

If we can maintain sharpness and responsiveness in this slow but sure technological transformation, we will eventually emerge unscathed.
