The data sharing step proceeds in the following order: Parsing step, interaction stage between DR and CNs, and finally the decryption and reward and punishment step. First, parsing step. The DR selects an AdvTx transaction, verifies its signature, and generates a commitment value. Then, DR sends a ReqTx transaction to the Smart Contract (SC), which validates the request and issues a MatchTx transaction to confirm the matching between DR and DO. Second, interaction step between the DR and the CN. The CN verifies the commitment value and, if successful, computes an encryption share for the DR. It then signs the encrypted share and submits a DRshareTx transaction via the SC.
