Oasis Network is a privacy-focused smart contract platform for open finance built using the Cosmos SDK. The project prioritizes applications and use-cases that promote data privacy and user confidentiality. It aims to achieve this goal by separating its consensus layer from its contract execution layer while providing a built-in interface connecting the two for privacy-preserving computation. The consensus layer acts as a hub that uses a Proof-of-Stake (PoS) mechanism to secure the network and reach a consensus on transaction validity. The execution layer consists of multiple, parallel runtimes (called ParaTimes) for specialized computation needs that each plug into the consensus layer.
