Shenchao Overview: For a long time, Ethereum founder Vitalik Buterin has been known for his minimalist lifestyle in the physical world—carrying only essential items in a single 40-liter backpack while constantly traveling across the globe. However, as smartphones, algorithm-driven information streams, and omnipresent instant messaging have thoroughly permeated modern life, physical minimalism is no longer sufficient to guard against total mental overload.

In this recent, lengthy personal blog post, Vitalik unusually and systematically shared his intense self-experiment with "digital minimalism" over the past few months. Most notably, he voluntarily disabled his phone’s cellular data and maintained a full 100 days of normal travel and high-intensity work life using only Wi-Fi connections at fixed locations.

This article not only documents Vitalik’s journey out of algorithmic information cocoons, his use of the Firefly aggregation client, and his exploration of offline maps and local small models with specific technical configurations, but also offers a profound philosophical and cognitive science-based analysis of how modern individuals can reclaim sovereignty over their attention from the grip of endless scrolling. DeepChain TechFlow has provided a complete, section-by-section translation of Vitalik’s heartfelt long-form essay, offering a highly insightful guide to mental decluttering for everyone grappling with the anxiety of today’s information deluge.

The full text is as follows:

For a long time, I have been a devoted advocate of physical minimalism: minimizing the number of physical items I own and striving to accomplish more with fewer resources. Four years ago, I wrote a blog post detailing exactly what I carried in my 40-liter backpack while traveling the world.

However, the concept of physical minimalism emerged and matured from the early 20th century through the 2010s, responding to the challenges and opportunities of that era.

I still firmly believe in the value of physical minimalism, even though I also acknowledge certain opposing views—for example, that owning certain “right kinds” of physical items can actually help you gain a more tangible sense of autonomy over your life. But in today’s era, what we need more than ever is a new kind of minimalism: digital minimalism.

The core of digital minimalism lies in consciously and intentionally controlling how you engage with digital technologies, ensuring that each use is a deliberate, mindful choice rather than an unconscious immersion driven by default habits.

In this article, I will share a series of real self-experiments I have conducted in this area.

Twitter (now the X platform) has long carried a certain toxic undertone, and this trend has intensified in recent years. While the platform is undoubtedly highly engaging, it often falls far short of being informative, and the way it captures your attention frequently leaves you feeling anything but uplifted.

For me, this negative experience peaked from late 2024 to early 2025. A lot happened during that time, but if you spent a lot of time on X, you likely remember an especially absurd phenomenon: it seemed as if everyone on the platform suddenly became a fan of Adolf Hitler.

This doesn’t even include the absurd incident where Grok itself briefly went out of control and transformed into “MechaHitler.”

Around the same time, the "crypto Twitter" community also fell into a collective sentiment widely described as "financial nihilism."

This argument roughly boils down to: the inherent endgame of blockchain is pure gambling, and that’s great; if you dislike this and expect blockchain to aspire to something greater, then you’re a pretentious, out-of-touch elitist jerk.

Naturally, I have always firmly disagreed with both of these trends, both in the past and today. But more importantly, I began to seriously reflect on the fact that, despite the platform’s highly engaging tone, it was neither insightful nor uplifting.

Therefore, for most of this year, I conducted a personal experiment: creating a moderate distance between myself and this chaos. I didn’t leave the X platform entirely, but I stepped away from its official client interface. Instead, I posted most of my tweets through Firefly:

Firefly is an all-in-one client that integrates X, BlueSky, Farcaster, and Lens (the latter two are decentralized social media platforms partially built on Ethereum). You can view updates from all four platforms in a single interface, and posting a single tweet automatically syncs across all four platforms.

My primary motivation for doing this is to support decentralized social media and diversify network effects, rather than reinforcing ecosystem lock-in, while continuing to engage on X.

But over the past few months of using Firefly, I’ve found that it has had an unexpected effect: my mental state feels much better when I use it.

I believe the core reason is that, although Firefly allows you to post and view others' tweets, it lacks the soul of the official X interface: the recommendation algorithm (The Algorithm™).

Specifically, I suspect that when I previously used X’s official interface, I fell into the following carefully designed vicious cycle trap:

First, you see an extreme tweet supporting Hitler. Driven by a morbid curiosity, similar to glancing at a car crash, you click on the tweet and scroll through its quoted tweets and comments.

At this moment, the "recommendation algorithm" thinks: "This user seems very interested in Hitler; let me mark this as one of their personal interest tags."

Then, in your feed, you saw ten tweets supporting Hitler. Once again, driven by a morbid curiosity, you clicked through to watch, just as someone might stop and stare upon witnessing ten cars crashing and bursting into flames for the first time.

The algorithm thinks: You don’t need me to say it—you can guess what I’m thinking. Then, you’ll see hundreds of tweets supporting Hitler in your feed.

To be fair, over the past year and a half, the extreme fan communities on the platform have significantly diminished—for X, Elon, and their hardworking employees.

I believe one reason is that such extreme ideologies inevitably exhaust themselves once the public recognizes their immorality and absurdity. But another reason is undoubtedly the actual improvement in the underlying mechanisms of recommendation algorithms.

Even so, in those rare moments when I must temporarily reopen the X official interface, I still find myself quickly logging out and retreating back to the peaceful world of Firefly.

I also noticed a profound shift in my mindset: I’ve grown increasingly uninterested in the various disputes that so-called “thought leaders” on the platform endlessly fight over each day.

I recently logged back in and discovered that the most heated cultural debate in the feed that day was people fiercely arguing whether a historical figure was truly evil. Seeing this felt to me like an adult unexpectedly encountering a snack, TV show, or game they were once obsessed with as a child—only to realize they now have zero interest in it. I smiled calmly, logged out, and returned to enjoying my own fulfilling day.

My conclusion and recommendation: I encourage more people to try this approach. Explore ways to significantly reduce or strictly limit your social media usage—such as using decentralized frontends like Firefly, or setting a rule to use X only on Tuesdays—and find a pace that works for you.

Gain real informational advantages from the platform, but never get caught in the vortex of algorithmic recommendations, as these algorithms subtly manipulate your emotions and mindset through powerful subconscious mechanisms you may not even notice.

For exactly 100 days, I conducted my second self-experiment: living with my phone permanently in airplane mode. During this time, I continued to use WiFi but completely cut off all cellular network connections.

I conducted this experiment primarily for two goals:

First, there are privacy concerns. A phone that is constantly connected to mobile cell towers is essentially a 24/7 personal location tracker. Telecom operators have a well-documented history of failing to protect user data, and sometimes they even sell this location data themselves.

Therefore, your actual movement patterns are highly likely to eventually end up in the hands of intelligence agencies, defense contractors, advertising companies, and other entities. Purchasing an anonymous SIM card is not a sufficient solution for two reasons: first, your phone can be uniquely identified and tracked throughout its lifetime via its IMEI number; second, fine-grained mobile location data and online behavior patterns easily reveal personal identity, and modern AI can now efficiently reconstruct and infer the real individuals behind these patterns.

Therefore, the most thorough location privacy solution is to not connect to any cellular network at all (in addition, I have been using the privacy-focused GrapheneOS system and strictly limit app permissions for location access).

Second, consider your mental health. Going completely offline for extended periods—especially while spending time outdoors—is an excellent way to rebuild the habit of "surviving offline." It can bring you greater inner peace and create mental space to reflect on healthier, more productive pursuits.

Overall, I believe this experiment was a resounding success. Over the 100 days, I technically broke the “no cellular network” rule once, but I did not violate it in spirit: I briefly enabled the network solely to receive a confirmation text message required to maintain my phone plan.

Another time, I made a spiritual breakthrough without literally breaking any promises: during a hike to a remote and slightly dangerous area, my friends insisted that I carry the emergency communication device they had prepared and required me to check in every few hours.

The greatest inconvenience I encountered during the entire experiment was my stay in Singapore. Because I was unable to receive SMS verification codes, I couldn't log in to the local ride-hailing app, Grab (similar to Uber in Southeast Asia).

As a result, my dining options were greatly limited, and even when public transportation was extremely inconvenient, I could only take the subway instead of a taxi.

After completing this 100-day formal experiment, although I occasionally turn on my mobile cellular connection, I have continued to maintain the habit of keeping "airplane mode on by default" for the vast majority of the time until today.

For outdoor navigation, I use CoMaps—a local-first offline map app that downloads OpenStreetMap data in advance and renders maps and plans routes entirely on your device.

My overall assessment of CoMaps is that it performs worse than Google Maps when it comes to exploring human-built commercial facilities such as restaurants, stores, and business hours; however, it outperforms Google Maps in navigating natural landscapes and outdoor trails, as it includes many hiking paths that Google Maps doesn't even recognize.

But it occasionally malfunctions, marking nonexistent footpaths on the map—once, this forced me to crawl through hundreds of meters of dense underbrush before I painfully stumbled back into civilization.

During this time, I also became deeply interested in the concept of a "local offline world knowledge base application." In principle, the data package containing valuable information from around the world is not as large as one might imagine.

The compressed English Wikipedia full-text dataset (excluding multimedia images) is only 27 GB. The OpenStreetMap global dataset (planet.osm) is approximately 2.2 TB, but if redundant information is removed and it is trimmed and compressed to 1% to 10% of its original size, it will be sufficient to include all the information you might need offline.

This month, Statuette organized a developer bounty competition (in which I participated as a sponsor) to incentivize developers to create mobile applications that can run offline directly on smartphones, enabling users to easily access practical knowledge anytime.

The two standout offline applications among the submitted entries are:

My overall feeling is that we are currently at a critical turning point where these offline tools are beginning to gain real practical value.

Most participants in the competition attempted to directly invoke on-device large language models via their mobile phones, waiting for the models to perform lengthy inference computations before delivering an answer. However, I believe this approach is too slow: answering a simple question often takes up to one minute, and in some cases, as long as 22 minutes.

In contrast, the top-performing application skillfully combines semantic search technology: it instantly displays precise search results from a local offline database, followed by a lightweight language model that automatically generates structured textual responses. This combination delivers exceptionally high-quality answers within an extremely reasonable response time.

Finally, when you're out and about—especially with a meeting schedule—it’s sometimes unavoidable to need a network connection while on the move.

When you arrive at a location, you often need to immediately contact the person you're meeting to confirm the exact spot or ask them to let you in; after a meeting ends, you frequently need to verify the details of your next appointment. If you don’t have cellular data, public Wi-Fi is your only lifeline—and critically, this public Wi-Fi hotspot must allow you to connect directly without requiring a SMS verification code.

Public network environments around the world vary drastically in terms of friendliness. Based on my travel experiences while paying special attention to public WiFi availability, I’ve compiled a quick tier ranking:

Tier One: Taiwan, China (at least in the Taipei area). Taipei has an extremely dense network of public WiFi hotspots. When I walk the streets or even pull out my phone while riding in an Uber, the probability of successfully detecting and connecting to a hotspot at any given moment exceeds 25%. These hotspots are typically provided free of charge by municipal public networks or convenience store chains scattered throughout the city.

Second tier: Ukraine, the United States, Canada, Singapore. Among these, Ukraine’s performance was the most surprising to me: in numerous areas across multiple cities, there are completely open, free Wi-Fi hotspots, many of which don’t even require web redirect verification.

The situation in the United States, Canada, and Singapore is similar: while the theoretical total number of public hotspots is very large, a significant portion require SMS verification or mandatory login. Even so, the number of truly fully open and accessible hotspots remains substantial.

Additionally, while searching for networks in Toronto, I accidentally discovered that there is a local fraternity (or sorority) apparently named after SBF (Sam Bankman-Fried):

Third tier: Austria and Hungary. These two regions, formerly part of the Austro-Hungarian Empire, have similar conditions: there are a fair number of hotspots, but most public networks require a mandatory SMS verification code to log in. Although occasionally you can find completely open hotspots, I’ve often had to try numerous networks one by one while wandering the streets for long periods.

Bottom tier: Switzerland. Although Switzerland enjoys an excellent reputation for privacy protection, I rank it last for public WiFi friendliness. Almost all public hotspots here require SMS verification codes. During my first 1.5 kilometers through downtown, I found only two exceptions: a random shoe store I passed by and Starbucks (Starbucks allows free connection for 10 minutes; to continue using the service, you must enter a verification code sent to your email).

Recently, I’ve been trying to completely move away from relying on web-based user interfaces for an increasing number of tasks.

When updating the IPFS hash on my ENS domain in recent instances, I used a command-line tool written for me by an AI. Now, I’ve also fully switched to the kohaku-cli command-line tool for all my on-chain payments made via privacy protocols:

Figure: Terminal demonstration of sending private transactions via the kohaku-cli command-line tool in low-bandwidth and offline environments.

The image above shows the process of sending a transaction using kohaku-cli. The command-line tool has now been simplified and made more user-friendly, eliminating the need for users to repeatedly specify values or understand what a tail call is.

In my view, traditional websites and web applications—especially those used for interacting with crypto assets—pose several fundamental security risks:

First is the risk of repeated trust and hacker hijacking. Every time you access a web application, your browser essentially re-downloads the entire application code from the server thousands of times, meaning you must fully trust the server each time you open the webpage. If the server is compromised or maliciously altered even once during those thousands of visits, your asset security could be completely breached. In contrast, traditional native download-and-install programs are more secure: you only need to trust that the server was not compromised at the single, precise moment of download and installation.

Second, it inherently violates user privacy. Websites and web applications are extremely unfriendly to user privacy by default. When you visit a webpage, it can easily detect your browser engine and version, operating system, and screen resolution; once you begin interacting, hundreds of granular data points—such as mouse movements and button-click frequency—are rapidly collected, making it simple to construct your digital fingerprint. Moreover, webpages often default to sharing this data and metadata with countless third-party services, ranging from CDN scripts to various data analytics companies.

Third is dark pattern design driven by commercial interests. As we’ve seen in social media, web applications crafted by third parties with commercial monetization goals often do not prioritize users’ best interests. Many subtle interface interactions are deliberately designed as “dark patterns” to exploit user attention, while what users truly desire are “bright patterns” that aim to enlighten, educate, and protect their personal rights.

Given these drawbacks, what alternatives do we have? The core idea is to revive the classic Unix philosophy and leverage local AI to transform it into a more user-friendly and accessible tool for everyday users: allowing you to issue commands to your computer in natural language, rather than being forced to write obscure Bash scripts.

The essence of the Unix philosophy is surprisingly simple: create small, modular tools, each focused on doing one thing well, and have them communicate and collaborate through the most universal standard interface—plain text.

As a user, you have extremely fine-grained autonomy to freely combine and customize different tools. In contrast, modern web interfaces often forcibly bundle countless complex features into a closed black-box tool controlled by a single development team. This trend has culminated in so-called super-apps, which concentrate immense power in the hands of platform developers, featuring highly complex and opaque internal mechanisms that significantly amplify systemic security risks.

Empowered by large language models, we can finally rediscover the elegant philosophy of Unix: returning fine-grained decision-making power to ordinary users while eliminating the high barrier that once required everyone to become a professional programmer.

The minimalist lifestyle that flourished in the physical world during the 2000s and 2010s became possible thanks to the widespread adoption of computer and internet technologies. A single lightweight computer could replace dozens of physical tools. As a result, you could live a highly free, exceptionally simple and pure life with just a laptop, a few changes of clothes, and basic charging and toiletry essentials.

Before the internet, physical minimalism was possible but often required significant lifestyle compromises and high costs; the advent of the internet has dramatically lowered the barrier to adopting a physically minimalist lifestyle.

With the significant advancements in software development quality over the past decade and the explosion of modern AI technologies, I believe we now have the underlying tech stack capable of sparking the next wave of digital minimalism.

We no longer rely as heavily on social media as we used to, because you can directly obtain high-value information from local intelligent bots (and for human emotional connection, the most classic and pure solution remains: step outside your door and talk face-to-face with real people in the real world);

We no longer rely on constant internet connectivity as we once did, because the range of tasks that can be accomplished in purely local and offline environments is now far greater than before;

We are no longer bound by the limitations of web-based interfaces, as you can now perform operations more conveniently and efficiently using command-line tools or customized interfaces, with AI ready to assist you in using or tailoring these tools at any time.

The maturity of all these technological conditions coincides with the peak of the drawbacks of the previous digital paradigm—and the secondary harms caused by the misuse of AI—making the practice of digital minimalism more urgent and necessary than ever.

The path to digital minimalism varies from person to person, as everyone’s practical needs and pace of life are different.

But I sincerely urge everyone to at least try cleaning up your digital clutter and mental noise in one important area. If you enjoy the clarity and calm this change brings, then confidently keep going.
