NuCypher is a decentralized encryption, access control and key management system (KMS), encryption service for public blockchains. NuCypher offers end-to-end encrypted data sharing on public blockchains and decentralized storage solutions. NuCypher allows users to share private data between a number of participants in public consensus networks, using proxy re-encryption (PRE) technology.?

This decryption technology makes NuCypher much more secure and protected than traditional blockchain projects based on public-key encryption, according to NuCypher. NuCypher (NU) are the native tokens used on the larger NuCypher network. The tokens are used to incentivize network participants for performing key management services and accessing delegation/revocation operations on the network. The NU tokens are also used for staking to run a NuCypher worker node. The NuCypher network is protected against malicious staking, and would automatically slash a suspected user’s rewards. NU is also used on the network for participating in the NuCypher DAO. The NuCypher DAO is the protocol that controls network parameters and smart contract upgrades on the network. Users who stake NU can also participate in validating DAO proposals.
