For example, a channel in a certain alliance has user nodes Org1, org2, org3 and Org4, wherein Org1 and Org2 are designated as endorsement nodes, org1 obtains an intelligent contract a through a contract mall plug-in deployed in the middle layer, and starts the intelligent contract a as an external contract service; org1 applies for the intelligent contract A to operate to the middle layer I, namely, generates a contract operation request; by responding to the contract running request, the contract mall plug-in of the middle layer I is triggered to check the legality of the contract A, the checking method is to compare the source file value (sha 256 value) of the contract source file and sign the checking information of the contract source file, if the contract provided by the contract mall is marked as Safe, otherwise, the contract is marked as not detected NotDetected or unsafe NotSafe.
The back user organization Org2 finds that the organization Org1 applies for contract A voting, the Org2 checks signature information of a mall, if the contract is a Safe label, the Org2 can check contract service logic and then can carry out signature agreement, if the contract is a NotDetected label, the Org2 can independently check or apply for third party checking, and if the contract is a Notsafe user organization Org2 can refuse to participate in voting; after the vote passes, the contract A really starts to run in the channel; i.e., deployed on a channel of a federation chain.
When an organization Org3 wants to add the organization to endorse the contract A, the organization needs to apply for 'modification of key-level endorsement policy' to the intermediate layer I, namely, an update request of endorsement policy data of the intelligent contract is generated, and a voting unit deployed on the intermediate layer is triggered to respond to the update request to generate a voting event; and the channel endorsement organizations Org1 and Org2 find the application of 'modification of key-level endorsement strategy', respond to the voting event, sign and vote the application, and the strategy modification is effective after the voting rule is satisfied, thereby completing the update of the endorsement strategy data.
