In a recent post, he said that 2026 should be the year computing self sovereignty regains lost ground. While blockchain plays a role, his message stretches far beyond crypto. At its core is a simple idea. People should not have to give away their data just to use modern software.
Over the past two years, Buterin has quietly changed the tools he relies on every day. In 2025, he moved away from centralized services by switching to Fileverse for encrypted documents and Signal as his main messaging app, replacing Telegram. He also installed privacy focused alternatives like SimpleX and Session.
Moving Away From Big Platforms
In 2026, Buterin continued that shift. He replaced Google Maps with OpenStreetMap and Organic Maps, which store maps locally on a device instead of tracking user location. He also moved from Gmail to Proton Mail and began prioritizing decentralized social media platforms. The goal is not perfection, but reducing how many companies know where you are, who you talk to, and what you write.
This trend is gaining traction. According to a 2024 report from Proton, demand for encrypted email and messaging surged after major data breaches and increased surveillance concerns. Signal alone surpassed 70 million monthly active users, showing that privacy focused tools are no longer niche.
2026 is the year we take back lost ground in computing self-sovereignty.
But this applies far beyond the blockchain world.
In 2025, I made two major changes to the software I use:
* Switched almost fully to https://t.co/caFP0K5fYF (open source encrypted decentralized docs)

A simple real world example helps explain the shift. When someone uses a local mapping app, their phone can guide them without constantly sending location data to a central server. That small change reduces digital exposure without sacrificing convenience.
Local AI and the Privacy Tradeoff
Buterin also highlighted progress and limits in local artificial intelligence. Local large language models run directly on personal devices instead of cloud servers. This means prompts and files stay on your computer. While the technology has improved rapidly, he notes the experience is still rough. Tools are scattered, power use can be high, and there is no single app that works as smoothly as popular cloud services.
To bridge that gap, he suggests combining imperfect solutions. These include per query payments using zero knowledge proofs, trusted execution environments, and local filters that remove sensitive data before anything is shared. In simple terms, these tools help computers prove they did a task correctly without revealing private details.
The message is clear. Sending all personal data to centralized services is not required anymore. The tools exist to do better, even if the experience is not yet seamless.
