A proxy re-encryption network to empower privacy in decentralized systems.
The NuCypher network facilitates end-to-end encrypted data sharing for distributed apps and protocols. Access permissions are baked into the underlying encryption, and access can only be explicitly granted by the data owner via sharing policies. Consequently, the data owner has ultimate control over access to their data. At no point is the data decrypted nor can the underlying private keys be determined by the NuCypher network.
Under the hood, the NuCypher network uses the Umbral threshold proxy re-encryption scheme to provide cryptographic access control.
pip3 install -U nucypher
Run a Federated-Only Development Ursula
nucypher ursula run --dev --federated-only
Configure a Persistent Ursula
nucypher ursula init --federated-only
Run a Persistent Ursula
nucypher ursula run --network <NETWORK_DOMAIN> --teacher-uri <SEEDNODE_URI> --federated-only
<NETWORK_DOMAIN> with the network domain and
<SEEDNODE_URI> with the URI of a node running on that network domain you want to connect to (for example 0.0.0.0:9151 or firstname.lastname@example.org:9151).
If you’re connecting to the
devnet, you should use
--network devnet --teacher-uri 126.96.36.199:9151.
Run a Geth-Connected Development Ursula
Run a local geth node in development mode:
Run a local development Ursula connected to the geth node
nucypher ursula run --dev --provider-uri ipc:///tmp/geth.ipc --checksum-address <GETH_DEV_ADDRESS>
<GETH_DEV_ADDRESS> with the geth node’s public checksum address.
