Your Cloud Data Is Not Yours
Recent events show cloud providers can't guarantee data privacy. The shift to zero-knowledge is here, and a new SDK makes it easy for developers to build truly sovereign apps.

⚡ The Signal
The unspoken agreement of the cloud was simple: we give you our data, you keep it safe. That trust is fundamentally broken. When Microsoft handed over BitLocker encryption keys to the FBI, it wasn't just a single compliance event; it was a confirmation of a structural vulnerability. The reality is, if your encryption keys live on a provider's server, they are not truly your keys. This has shattered the illusion of cloud privacy and ignited a search for a new paradigm where users, not platforms, hold the keys.
🚧 The Problem
Developers are caught in the middle. Users are demanding data sovereignty, but building "zero-knowledge" applications is brutally difficult. Implementing robust, client-side encryption and managing key synchronization across a user's multiple devices (laptop, phone, tablet) is a complex cryptographic challenge. It's a massive distraction from building the core product, requiring specialized expertise that most teams don't have. There is no simple, developer-friendly toolkit to build applications where the platform is physically incapable of accessing user data.
🚀 The Solution
Rhizome is a simple SDK for building zero-knowledge apps. It provides developers with a toolkit to ensure user data is encrypted on the client's device, and the keys never touch a central server. Rhizome’s core innovation is its managed peer-to-peer signaling service, which allows a user's devices to securely synchronize encryption keys directly with each other. For the developer, it’s a few lines of code. For the end-user, it’s true data ownership. This enables a new class of applications that are private by design, aligning with the broader tech shift toward on-device processing.
