The Ethereum Foundation has activated zkAPI on the Ethereum mainnet, enabling anonymous payment of API fees for AI services. Built jointly with the Open Anonymity Project, the system lets users deposit ETH or USDC into a smart contract and prove only that they hold sufficient balance using zero-knowledge proofs. Servers verify proofs and issue short-lived API keys. The article notes potential limits such as IP-based correlation and repeated personal signals across sessions.

AhnLab said on Thursday it released security guidelines for users and service operators amid a string of account and personal data leaks. It recommended using different passwords for each service, enabling multi-factor authentication and regularly checking login history and security settings. The company also urged caution over suspicious links and phishing messages and called for browser password management and timely security updates. For operators, it stressed API access control and monitoring for abnormal behavior.
