Imagine Ethereum as a bustling city that’s been growing too fast—its roads are clogged, transactions take forever, and everyone wishes for a smoother ride. That’s where the Fusaka fork comes in, like a major infrastructure overhaul that’s just cleared its last rehearsal on the Hoodi testnet. This isn’t just another tweak; it’s a game-changer set to hit the mainnet on Dec. 3, bringing scalability and security boosts that could redefine how we interact with the blockchain. If you’ve been following Ethereum’s journey, you know it’s all about balancing that tricky blockchain trilemma—decentralization, security, and scalability. Fusaka is Ethereum’s bold move to fine-tune the scalability part without sacrificing the rest. Let’s dive into what this means for you, whether you’re a developer, investor, or just someone curious about where crypto is headed.

As we sit here in late 2025, reflecting on how Ethereum has evolved, it’s clear that upgrades like Fusaka are more than technical jargon—they’re the pulse of a network that’s adapting to real-world demands. Think about it: back when Ethereum first launched, it prioritized being secure and decentralized, almost like building a fortress before worrying about the highways leading to it. But as more people flocked in, those highways got jammed. Fusaka is like adding express lanes and smart traffic systems, making everything run faster and safer. And with platforms like WEEX stepping up to integrate these changes seamlessly, trading ETH feels less like navigating a maze and more like a straightforward drive.

The Road to Fusaka: From Testnet Triumph to Mainnet Milestone

Ethereum’s Fusaka update made its debut on the Hoodi testnet, the last stop before the big mainnet launch. This final testnet phase went off without a hitch, as noted by validator client teams who celebrated the smooth transition. It’s slated to introduce a suite of improvements that tackle both security and scalability head-on, ensuring the network can handle the growing demands of decentralized applications and users worldwide.

Picture this upgrade as Ethereum’s way of upgrading from a single-lane road to a multi-lane freeway. One of the standout features is Peer Data Availability Sampling, or PeerDAS, baked into EIP-7594. This allows validators to process smaller chunks of data from layer 2 networks instead of dealing with massive blobs, which streamlines operations and boosts overall node efficiency. It’s like breaking down a huge shipment into manageable packages—easier to handle, less chance of bottlenecks.

Then there are EIPs like 7825 and 7935, which crank up the gas limit and pave the way for parallel execution. Imagine smart contracts as tasks in a busy office; right now, they’re handled one by one, but Fusaka sets the stage for multitasking, processing multiple contracts simultaneously. This isn’t just about speed—it’s about making Ethereum more efficient for everyday use, from DeFi trades to NFT minting. Other EIPs in the mix focus on zero-knowledge rollups, those clever tech layers that bundle transactions off-chain before settling them on Ethereum, further enhancing privacy and throughput.

This milestone arrives amid some turbulence, with key figures at the Ethereum Foundation stepping away and voicing concerns about the network’s direction. Yet, the tech presses on, proving Ethereum’s resilience. Meanwhile, Ether itself has been on a tear, hitting all-time highs fueled by ETF investments and companies adding it to their treasuries. It’s a reminder that while leadership shifts happen, the underlying tech and market enthusiasm keep the engine running.

For traders, this is where platforms like WEEX shine. As a reliable exchange, WEEX has been quick to align with Ethereum’s upgrades, offering tools that let you trade ETH with low fees and high liquidity. It’s not just about riding the wave of Fusaka’s improvements; it’s about having a partner that makes those benefits accessible, enhancing your overall experience in the crypto space.

Breaking Down the Fusaka Process: A Three-Stage Rollout for Ethereum’s Future

Fusaka isn’t a one-and-done event—it’s structured in three deliberate stages to ensure everything rolls out smoothly. First comes the mainnet launch itself, activating the core upgrade. Then, an EIP kicks in to increase blob capacity, essentially giving the network more room to breathe. Finally, a second hard fork boosts that capacity even further, solidifying the scalability gains.

This phased approach is smart, like testing a new bridge in sections before letting full traffic through. It minimizes risks and allows the community to adapt. Once Fusaka is fully live, the focus shifts to the Glamsterdam upgrade, part of Ethereum’s broader “Surge” roadmap. This roadmap is all about scaling up, making Ethereum capable of handling massive transaction volumes without compromising its decentralized ethos.

Compare this to rivals like Solana or Sui, which have bet big on scalability from the start, offering lightning-fast transactions. Ethereum, by design, chose a different path, emphasizing security and decentralization first—like building a bank vault before installing the ATMs. Fusaka bridges that gap, using innovations like PeerDAS to make Ethereum competitive without losing its core strengths. Evidence backs this up: post-upgrade simulations show potential for handling thousands more transactions per second, drawing from real-world testnet data where nodes processed data chunks efficiently.

In the context of 2025, as we look back, Fusaka’s rollout has sparked discussions on how it positions Ethereum against these competitors. On Twitter, topics like “#EthereumScalability” and “#FusakaUpgrade” have trended, with users debating if this finally puts Ethereum on par with faster chains. Official announcements from Ethereum developers, shared via posts, emphasize the security enhancements, reassuring the community that scalability isn’t coming at the expense of safety.

Tackling the Blockchain Trilemma: How Fusaka Enhances Ethereum’s Scalability

At the heart of Fusaka is Ethereum’s ongoing battle with the blockchain trilemma, a concept introduced by co-founder Vitalik Buterin. It’s like juggling three balls—decentralization, security, and scalability—and Ethereum has historically dropped the scalability one to keep the others in the air. Fusaka picks it back up, fine-tuning the network to process more without centralizing power or weakening defenses.

Think of scalability as the network’s bandwidth. Right now, Ethereum handles a solid but limited number of transactions, leading to high fees during peak times. Fusaka’s EIPs address this by optimizing data handling and gas usage, potentially reducing costs and wait times. Real-world examples abound: during busy periods like major NFT drops, users have faced delays, but post-Fusaka projections suggest smoother sailing, supported by testnet results where efficiency improved noticeably.

This upgrade follows hot on the heels of Pectra, which happened about six months prior and honed in on staking and user interfaces. Together, they’re building a more user-friendly Ethereum, one that’s not just for tech wizards but for everyday folks dipping into crypto. And as Ether hits those highs, it’s clear the market believes in this direction—ETFs have poured in, and corporate adoption is rising, painting a picture of Ethereum as a maturing asset.

Integrating this with trading platforms, WEEX stands out by providing real-time updates on Ethereum upgrades, ensuring users can adjust strategies accordingly. It’s this kind of brand alignment that builds trust, positioning WEEX as a go-to for navigating Ethereum’s evolving landscape without the hassle.

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.
