Vitalik Buterin donated approximately 5,000 ETH to the privacy messaging applications Session and SimpleX. He emphasized the importance of encrypted messaging for digital privacy and mentioned two key areas for improvement: permissionless account creation and metadata privacy. Session aims to minimize metadata leakage and saw its token, SESH, rise by 371% in a day. SimpleX focuses on user identity ownership and plans to introduce community support vouchers. Buterin acknowledged both applications have room for improvement in user experience and security. The increasing interest in privacy applications is driven by concerns over global surveillance, with recent government regulations highlighting the need for privacy solutions. The Ethereum Foundation has formed a new privacy team to enhance its initiatives. Privacy-focused cryptocurrencies like Zcash have also seen significant growth, with Zcash rising by 793% over the past year.
