The post Vitalik Buterin’s 2026 Self-Sovereign Tech Stack appeared on BitcoinEthereumNews.com.

Ethereum cofounder Vitalik Buterin declared 2026 to be the “year we take back lost ground in computing self-sovereignty,” starting with his own devices.  In a Friday post on X, he laid out the software changes he has made to reduce reliance on data-hungry, centralized platforms. The “two major changes” to the software he used in 2025 were switching “almost fully” to Fileverse, an open-source, decentralized document platform — a kind of privacy-preserving Google Docs — and switching “decisively” to Signal as his primary messaging app. Signal uses end-to-end encryption by default for all one-to-one and group chats, and stores minimal metadata, meaning only limited information, such as when an account was created or the last date it connected to the service. Telegram, in contrast, only offers end-to-end encryption in optional “secret chats” and otherwise keeps messages and metadata on its own servers, a model that has drawn scrutiny as law enforcement data requests have increased in countries like France.

Buterin also discussed his experiments with locally hosting large language models, arguing that sending all data to third-party services is “unnecessary” when users can increasingly run artificial intelligence tools on their own hardware.  He said better user interfaces, integrations and efficiency are still needed to make local models a seamless default, but added that there has already been “huge progress” compared with a year ago.  Privacy advocates see broader shift His post echoes points made by privacy advocate and NBTV founder Naomi Brockwell, who described running models locally as the most private way to…
