According to Foresight News, during a discussion on the Bankless podcast about whether blockchain technology can facilitate secure communication among citizens of autocratic nations, Vitalik introduced a company named Rarimo, based in Kiev, Ukraine. The company has developed a tool called 'Freedom Tool' that uses zero-knowledge proof technology to allow Russian citizens to verify their citizenship and participate in online voting without revealing their identities. This system ensures tamper-proof and visible results, thereby creating a form of anonymous, censorship-resistant voting.
