These services offload bid computation and ad scoring to a cloud-based trusted execution environment (TEE). User data is encrypted and only accessible to these services, protecting privacy. Ad tech code runs in an isolated V8 engine within the TEE. Testing for Chrome's Bidding and Auction services starts mid-2023, with scaled testing by the year's end.\n"]]
