According to The Block, the Ethereum Foundation launched a new service called zkAPI that enables users to pay for AI models without revealing their identity. Users place funds into an Ethereum vault and use zero-knowledge proofs to authorize spending. This mechanism prevents the API provider from linking any payment request to a specific user’s identifying information.
The feature allows individuals or organizations to cover costs associated with AI model usage through the vaulted deposit, while maintaining privacy regarding who made the payment. The Ethereum Foundation described the approach as designed to support secure, private transactions for AI services without requiring traditional identification from payers.
