AI's rapid advancement has sparked discussions about its governance, particularly in relation to deepfakes and identity validation. Cryptocurrency and blockchain technologies may offer solutions. For instance, blockchain's immutable ledgers could validate the authenticity of media content, while digital identity infrastructure based on biometric authentication and zero-knowledge proofs could offer robust identity validation. Furthermore, AI agents capable of complex actions on behalf of humans may soon enter the market. Stablecoins, with their one-to-one parity with USD, could facilitate financial transactions involving these AI agents. Policymakers are urged to embrace these technologies to guide AI towards beneficial ends.
