Oasis Network is a smart contract system based on privacy protection, based on COSMOS SDK. This project mainly focuses on applications and scenarios that promotes data privacy and confidentiality of user confidentiality. Thanks to OASIS's COSMOS SDK basics, when the IBC (cross -chain communications) protocol takes effect, OASIS will have the opportunity to integrate into the ecosystem that supports more cosmos chains (that is, region).The uniqueness of OASIS is that it separates the consensus layer and the contract execution layer. Through this layered strategy, Oasis can flexibly adapt to a variety of adjustable operating environments, that is, the paraatimes it calls. This mode is somewhat similar to Avalanche's subnet strategy or Polkadot's parallel chain strategy.On OASIS, the privacy protection function brings a new concept of data token, which allows users to dominate their own data and can get corresponding rewards through various applications to build an encouraging data economy system. Thanks to the support of confidential intelligence contracts, the data during processing always keeps confidential. This data confidentiality strategy on the blockchain is a DEFI scenario, such as the lack of mortgage loans and the front -end/back -end operating strategy, which provides possibilities.
