Confidential Data Rails | A Hackathon
Build apps that use private data without giving up composability., The CDR Hackathon is a focused virtual event for developers exploring a new primitive powered by Story’s Confidential Data Rails: programmable private data onchain.
About
Instead of hiding sensitive data entirely offchain, CDR lets developers create encrypted objects with dynamic access control, composable permissions, and verifiable compute. Build things like: Private AI agents with encrypted memory Data marketplaces and subscription access Confidential order books and coordination systems Medical, identity, or financial apps with programmable privacy Autonomous onchain objects with private state Completely unhinged experiments nobody has thought of yet There will be $3,000 in prizes spread across 3 winners. https://build.usecdr.dev
