Vitalik Backs Session and SimpleX Chat, Highlights Privacy Messaging as Key Trend

According to Jinse, on November 27, 2025, Vitalik Buterin endorsed two decentralized messaging apps, Session and SimpleX Chat, donating 128 ETH to each. He emphasized the importance of digital privacy in encrypted messaging, highlighting two key directions: permissionless account creation and metadata privacy protection. Session, developed by the Oxen Privacy Tech Foundation and later the Session Technology Foundation, is a decentralized, end-to-end encrypted messaging tool that uses a 66-character alphanumeric identifier instead of phone numbers or emails. It migrated to its own blockchain, Session Network, in 2025. SimpleX Chat is another open-source messaging app that does not require user identifiers and uses a one-way message protocol to protect metadata. Both apps aim to address growing concerns over privacy in the wake of regulatory pressures like the EU’s proposed 'chat control' measures. Vitalik’s support signals a growing industry focus on privacy infrastructure in Web3.
