Vitalik Buterin, co-founder of Ethereum, discussed the potential of crypto identity solutions to address the challenges associated with airdrops. He highlighted that airdrops, while distributing billions in value, often face issues with users gaming the system by using multiple wallets. Buterin suggested using zero-knowledge proof technology and blockchain-based identity frameworks to ensure tokens are distributed fairly among genuine community members and to reward contributions. He emphasized that this approach could also be used to compensate various forms of currently uncompensated work across the economy.
