As part of WhatsApp’s new feature to privately add and manage your contacts on WhatsApp across linked devices, we’re announcing a novel encrypted storage system we’ve designed called Identity Proof Linked Storage (IPLS). IPLS is a novel system at WhatsApp that allows users to store their contact names in an encrypted way.
