NuCypher is a security and encryption platform for distributed systems, including big data, cloud, blockchain, and Internet of Things. NuCypher is a new-generation cryptocurrency platform that specializes in blockchain security, using advanced cryptography. The entity is the provider of a security and encryption platform intended to offer accessible, intuitive, and extensible runtimes and interfaces for secrets management and dynamic access control. A data privacy layer for blockchain and decentralized applications, NuCypher gives developers a way to store, share, and manage private data on public blockchains. NuCypher describes itself as a threshold cryptography network that provides data privacy and key management for decentralized applications and protocols.

  • At its core, NuCypher is a blockchain protocol with a focus on enhancing privacy for its users.

  • NuCypher’s proxy re-encryption protocol lets users share private data on a public blockchain securely, thus eliminating the need for a separate private network such as a VPN.

  • NuCypher’s USP is its ability to offer advanced privacy layers in a decentralized environment.

  • In 2017, the NuCypher network started to focus on providing services to decentralized networks.

  • Currently, this network offers services to industries that deal with huge volumes of sensitive data, for instance healthcare and banking.



  • Manage secrets such as IAM tokens, database and SSH credentials, and signing/encryption keys across dynamic environments.

  • Conditionally grant and revoke access to sensitive data to arbitrary numbers of recipients.

  • Process encrypted data while preserving the confidentiality of the inputs and results.
