Blockchain
The brief introduction of SCRY.INFO protocol layer By providing SDK for data exchange through blockchain, developers can more conveniently develop DAPP applications. It mainly includes the following contents: data encryption and decryption, digital signature, smart contract, event notification, data storage interface, data acquisition and query, digital currency payment, the third-party App payment interface, etc. The process is as follows: The data provider writes data and metadata through SDK (data includes static data and dynamic data which have the agreed format; metadata mainly includes data signature, data description, and other information); the data demander can find the required data through SDK and obtain the data after paying digital currency. The data verifier becomes one by pledging a certain amount of digital currency to the smart contract. In the process of data exchange, the data demander can initiate the compensable data verification request or transaction arbitration to the smart contract, and the verifier is randomly selected by the smart contract. All participants in the data exchange can score each other in the transactions；The smart contract would record the transaction and scoring information of the participants and generate the reputation evaluation of the participants. The reputation evaluation information can be inquired through SDK.
