Buterin said 2026 should mark a push toward computing self-sovereignty, extending far beyond blockchain systems.
Ethereum co-founder Vitalik Buterin has said he spent the past year replacing mainstream software with privacy-first, decentralized alternatives, arguing that users should stop sending large volumes of personal data to centralized services.
The comments frame privacy tools not as niche crypto products but as everyday software choices, linking personal computing habits to broader debates about digital autonomy.
From Blockchain to Daily Software Choices
In a post shared on X on January 22, Buterin wrote that “2026 is the year we take back lost ground in computing self-sovereignty,” adding that the idea extends well beyond blockchain systems. He detailed a series of changes made since 2025, including a near-complete switch to Fileverse for encrypted document storage and a move away from Telegram toward Signal, SimpleX, and Session for messaging.
The developer added that he has replaced Google Maps with OpenStreetMap-based tools such as Organic Maps, citing the value of local data storage and reduced location tracking. He also moved from Gmail to Proton Mail, while stressing that encrypted messaging remains the safer option for sensitive communication.
Buterin also discussed ongoing work with local large language models, saying progress has been rapid, but user experience remains fragmented. He noted that while many capable local models now exist, they lack integrated tools comparable to mainstream services for translation, transcription, and document search. Running local models full-time, he added, still comes with practical costs such as high power use.
The post builds on comments from earlier this month, when Buterin said he plans to rely fully on decentralized social media in 2026. At the time, the 31-year-old said he already posts through Firefly, a multi-client platform that connects to X, Lens, Farcaster, and Bluesky, and criticized social platforms that optimize for engagement while limiting competition through closed data systems.
Privacy Concerns and the Push for a Sovereign Web
Buterin’s focus on everyday privacy tools follows a series of warnings about data collection by major platforms. In November 2025, he criticized X’s country-label feature, arguing that even partial location signals could place some users at risk. He said geo-inference systems can be gamed by sophisticated actors while exposing less protected users to unwanted attention.

That same month, he donated 256 ETH to the encrypted messaging projects Session and SimpleX, backing efforts to remove phone-number requirements and reduce metadata leakage. While he has praised Signal for its adoption, he has also acknowledged its limits, especially after U.S. defense officials raised concerns in March 2025 about targeted phishing attacks linked to devices.
Taken together, his recent comments point to a consistent view: privacy tools already exist, but wider use depends on usability, integration, and a shift in user habits. Rather than calling for new laws or platforms, Buterin has focused on adoption through personal choice, arguing that sending all personal data to centralized services is optional, not inevitable.
