An example operation may include one or more of receiving, by one or more endorser nodes of a blockchain network, an invoke chaincode transaction proposal, executing chaincode, encrypting, by an application programming interface between the chaincode and a shared ledger, blockchain state to the shared ledger, decrypting blockchain state from the shared ledger, endorsing, by the one or more endorser nodes, one or more results from executing the chaincode, and creating a blockchain transaction from the one or more endorsed results.

The invention discloses a message processing method and device based on a block chain, equipment and a storage medium, relates to the technical field of block chains, and can be used for cloud computing and cloud service. The specific implementation scheme is as follows: writing message data into a message queue intelligent contract, wherein the message data is obtained from a message uplink transaction request initiated by a producer node based on the message queue smart contract; and calling the message queue smart contract, and sending the message data to a consumer node. According to the invention, the reliability and security of the message data can be improved.
