⚙️ A decentralized COnfiguration service with Signing and Encryption on the Internet Computer.
💝 Backed by a $25k Developer Grant from the DFINITY Foundation.
IC COSE is a fully open-source decentralized configuration service running on the Internet Computer. Based on the CBOR Object Signing and Encryption (COSE, RFC9052) standard, it offers centralized message signing and configuration data encryption. Configuration data is organized by namespaces and client subjects, supporting collaboration, fine-grained access control, and horizontal scalability. It can serve as a reliable and secure configuration center for various Web3 services and Web2 services with high data security and reliability requirements.
A imaginative use case is serving as a state persistence service for enclaves running in Trusted Execution Environments (TEEs), aiding in loading confidential data during startup and persisting confidential data states during runtime.
- Supports message signing and configuration data encryption (COSE, Threshold ECDSA, Threshold Schnorr, VetKeys (TODO)).
- Organizes configuration data by namespaces and client subjects with fine-grained access control.
- Serve as a state persistence service for enclaves, aiding in loading and persisting confidential data during startup and runtime.
- Supports horizontal scalability, WASM upgrade management, and Cycles recharge management.
- Can be used as a cluster management center for both Web3 and Web2 services.
