[Ethereum Foundation and Open Anonymity Project Launch zkAPI on Mainnet] Odaily Planet Daily News: The Ethereum Foundation and Open Anonymity Project launched zkAPI on the Ethereum mainnet on October 1. This system allows users to pre-deposit amounts in ETH, USDC, and other currencies to separate billing identities from requests when paying for AI and other usage-based services. After depositing funds, users can authorize payments through zero-knowledge proofs and one-time API keys. Once the server verifies the payment proof, it generates a short-term key with a spending limit. AI service providers can receive prompts but will not know the corresponding payment identity. zkAPI does not hide the content of prompts; AI service providers can still read prompts and responses. Stable IP addresses, time patterns, and repetitive behaviors may still link to user identities. The project's codebase labels zkAPI as an experimental project. (Bitcoin.com News)
