Vitalik Buterin published a post on Oct. 31 describing experiments in digital minimalism, including using Firefly to post across four social networks and avoiding cellular connections for 100 days. He says the changes helped him reduce exposure to social media feeds and address privacy concerns, but the post does not provide measured outcomes or a full account of the phone experiment.
Vitalik Buterin has described experiments in digital minimalism, including replacing X’s interface with the multi-platform client Firefly and keeping his phone in airplane mode for 100 days. In a post published Oct. 31, the Ethereum co-founder said the changes were intended to make technology use more deliberate, reduce exposure to social media feeds, and address concerns about cellular tracking.
Buterin said he continued posting to X but largely stopped using its app and website interface, instead using Firefly, which combines X, Bluesky, Farcaster and Lens. The client lets users view posts from the services and publish a post across them. He said his initial reason was to support decentralized social media by distributing network effects rather than concentrating them on one platform.
He also reported a personal change in how social media felt. Buterin said Firefly’s lack of X’s recommendation algorithm appeared to be a major reason he felt better using it. He described a pattern in which clicking on provocative posts out of morbid curiosity could lead a recommendation system to show more similar material. This is his account of his experience and an explanation he suspects, not a measured study of the platform’s recommendation system.
A second experiment lasted 100 days: Buterin said his phone remained in airplane mode while he used Wi-Fi. He gave privacy as one of two goals, arguing that a phone connected to cellular networks can be used to track its location and that carrier-held data can be poorly secured or sold. The supplied post excerpt does not include his explanation of the second goal or the full results of the experiment.
Reducing Feeds Without Leaving Platforms
Buterin’s account focuses on changing the route into digital services rather than abandoning them. Using a multi-client let him continue to reach audiences on X while also posting to other networks, and avoiding the platform’s main interface reduced his contact with its recommendation feed, according to his report.
The approach may interest people who want to stay reachable or informed without opening a service in its most engaging format. But the post is a personal account, not evidence that Firefly will have the same effect for other users or that using airplane mode removes all phone-location risks. Its practical value depends on trade-offs such as access to calls and cellular data, which the excerpt does not detail.

From Physical to Digital Minimalism
Buterin framed the experiments as an extension of his longstanding interest in physical minimalism. He recalled writing about the contents of a 40-liter travel backpack four years earlier, while arguing that the current era calls for more attention to how people use digital tools.
He defined digital minimalism as being intentional about access to technology, so that each use is a conscious choice rather than a default habit. His discussion of X was tied to his perception of increasingly toxic and uninformative discourse around late 2024 and early 2025. He cited what he saw as a surge in posts praising Adolf Hitler and a mood in crypto communities he characterized as “financial nihilism.” Those descriptions are Buterin’s characterization of online discourse, not independently quantified findings in the source.
Buterin also acknowledged that the political content he criticized had since diminished, and said changes to X’s recommendation system may have contributed. His account therefore describes both a personal response to a particular period and a continuing effort to limit his exposure to the platform’s interface.
Limits of the Personal Experiments
The post presents personal observations, not controlled research. It does not quantify how much time Buterin spent on social media before or after switching clients, how often he used Firefly, or whether the change affected the information he encountered overall. His explanation about recommendation algorithms is explicitly framed as a suspicion about his own experience.
The supplied material also cuts off during the discussion of the 100-day airplane-mode experiment. It names privacy as one goal but does not state the second goal or report the experiment’s full effects. It does not establish how the phone handled emergency calls, location services, or other connectivity, and it offers no independent assessment of carrier data practices.
Testing Changes to Digital Habits
Buterin did not announce a formal study, product launch or follow-up date. He suggested that readers try practical limits that suit their circumstances, such as using a multi-client or restricting access to X to one day a week. His stated aim was to retain access to information while avoiding what he called the platform’s “vortex.”
The next development is whether he publishes the missing details or longer-term results of the phone experiment. For readers considering similar changes, the post offers examples rather than a tested program: its results are personal, and the trade-offs of limiting cellular access will vary with work, safety and communication needs.
Key Questions
What did Vitalik Buterin mean by digital minimalism?
He described it as using digital technology intentionally, making access a conscious choice rather than a default habit.
Why did Buterin switch from X’s interface to Firefly?
He said Firefly let him post to X, Bluesky, Farcaster and Lens while supporting decentralized social media. He also suspected that not having X’s recommendation algorithm helped him feel better while using it.
Did Buterin leave X?
No. He said he continued using the platform to post, but mostly accessed it through Firefly rather than X’s own interface.
What was the 100-day phone experiment?
Buterin said he kept his phone in airplane mode for 100 days while still using Wi-Fi. He identified privacy as one goal, but the supplied post excerpt does not include the second goal or complete results.
