Abstract
A data processing method includes: determining, in response to a request of an access terminal for writing target data to a blockchain, a target node role with a read permission for the target data, an access terminal connected with each node device having a permission of a node role corresponding to the node device; acquiring an encryption key corresponding to the target node role; performing encryption processing on the target data according to the encryption key to obtain a cipher text corresponding to the target data, the cipher text corresponding to the target data being decryptable for an access terminal corresponding to the target node role; and storing the cipher text corresponding to the target data to the blockchain.
