According to Foresight News, Vitalik introduced a company called Rarimo when discussing whether blockchain technology can enable secure communication between citizens in authoritarian countries in the Bankless podcast. The company is headquartered in Kiev, Ukraine, and has developed a tool called "Freedom Tool". The tool uses zero-knowledge proof technology to allow Russian citizens to prove their citizenship and participate in online voting without revealing their identities. The system ensures that the results are tamper-proof and visible, creating an anonymous, censorship-resistant form of voting.
