The embodiment of the invention provides a block chain-based data processing method and system, and the method comprises the steps: receiving a ciphertext transaction request submitted by any target business system in at least one business system, the ciphertext transaction request is obtained by adopting a key provided by a transaction alliance sharing data on a block chain to sign target data; processing the ciphertext transaction request through a target smart contract accepted by the transaction alliance to obtain target summary information of the target data and identification information corresponding to the target summary information; and returning the identification information to the target business system, sending the target summary information and the identification information to a block chain network for consensus processing, and generating a target block and target account book data corresponding to the target block. According to the scheme of the invention, data sharing among different service
