Sinopsis

NuCypher is a decentralized threshold cryptography network offering interfaces and runtimes for secrets management and dynamic access control. It provides cryptographic infrastructure for privacy preserving applications and it exists as a smart contract on the Ethereum blockchain. They are currently in testnet but once launched you will be able to use NuCypher to carry out proxy re-encryption.Proxy re-encryption is a cryptographic method that allows you to delegate re-encryption of data to a third party and in this case validators in the NuCypher network. With this method you issue a re-encryption key that is assigned to a specific public key and a third party has the ability to re-encrypt data for that third party to decrypt. In this case the NuCypher network acts as the third party service. It is useful for when you want to share data, with the ability to revoke access at a later stage. They also have an interesting token distribution mechanism called the WorkLock. This is similar to a Lockdrop but with wor
