The getblockchaininfo RPC now exposes progress for background validation if the assumeutxo feature is used. Once a node has synced from snapshot to tip, verificationprogress returns 1.0 and initialblockdownload false even though the node may still be validating blocks in the background. A new object, backgroundvalidation, provides details about the snapshot being validated, including snapshot height, number of blocks processed, best block hash, chainwork, median time, and verification progress.
