NuCypher KMS: Uncensorable decentralized encryption service

We introduce NuCypher KMS: decentralized key management network. Unlike traditional key management systems, it only re-encrypts data and never decrypts. Access permissions are represented by re-encryption keys which are used by our threshold split-key re-encryption scheme [Umbral]. The talk explains how the system works, token economics behind the network, and how to build multu-user end-to-end encrypted applications with it.
