In some application scenarios, it is required that the custom credential issued in the contract and the custom credential issued in the blockchain can communicate with each other, and both schemes for issuing the custom credential in the prior art cannot be realized for the requirement. The current intelligent contract issues the self-defined evidence, and because the state and the operation logic of the contract are completed by the contract, the safety and the reliability of the contract are questioned, and the security loophole appears for many times. In addition, for the self-defined certification in the block chain, the operation is limited by a node program, and the self-defined certification is not as good as the programmable mode of an intelligent contract which has the characteristics of self-defined operation logic and automatic execution.

2. The custom negotiable method according to claim 1, wherein the custom negotiable operation comprises error message return, account attribute setting, transaction rate setting, trusted gateway setting, trusted credit setting, gateway balance inquiry and/or gateway negotiable transaction.
3. The custom evidence circulation method according to claim 1, wherein the configuring of the gateway operation instruction corresponding to the custom evidence operation in the ethernet virtual machine corresponding to the intelligent contract specifically includes:
adding an operation function corresponding to the custom pass-evidence operation in an Ether shop virtual machine corresponding to the intelligent contract;
and compiling the operation function through a compiling tool to obtain a gateway operation instruction.
4. The method of claim 1, wherein the blockchain node performs a transaction consensus after the custom certification operation is completed, and before the method further comprises:
and carrying out data uplink on the evidence-passing instruction parameters when the block link points execute the user-defined evidence-passing operation.
5. A custom passport circulation system, comprising:
a configuration unit, configured to perform relevant configuration in the intelligent contract and the blockchain network, where the relevant configuration includes: configuring a gateway operation instruction corresponding to a custom pass-evidence operation in an Ethernet shop virtual machine corresponding to an intelligent contract and configuring an interface corresponding to the gateway operation instruction in the intelligent contract and a block chain network;
the calling unit is used for calling the Ethernet workshop virtual machine to execute the intelligent contract when the block chain node receives intelligent contract calling transaction, and the transaction comprises custom evidence-defining operation;
the first callback unit is used for calling back the gateway operation instruction to the blockchain node through the interface when the gateway operation instruction is obtained through analysis in the process that the Ethernet workshop virtual machine executes the intelligent contract, so that the blockchain node executes the custom certification operation corresponding to the gateway operation instruction;
the transaction consensus unit is used for performing transaction consensus after the user-defined certification operation is executed on the block link point;
and the second callback unit is used for calling back the transaction consensus result to the intelligent contract through the block link point after the transaction consensus passes.
6. The custom negotiable system according to claim 5, wherein said custom negotiable operation comprises error message return, account attribute setting, transaction rate setting, trusted gateway setting, trusted credit setting, gateway balance inquiry and/or gateway negotiable transaction.
7. The custom certification circulation system according to claim 5, wherein the configuring of the gateway operation instruction corresponding to the custom certification operation in the ethernet virtual machine corresponding to the intelligent contract specifically includes:
adding an operation function corresponding to the custom pass-evidence operation in an Ether shop virtual machine corresponding to the intelligent contract;
and compiling the operation function through a compiling tool to obtain a gateway operation instruction.
8. The custom credential circulation system according to claim 5, further comprising:
and the data uplink unit is used for performing data uplink on the evidence-passing instruction parameters when the block link points execute the user-defined evidence-passing operation.
9. An electronic device, comprising a processor and a memory;
the memory is used for storing program codes and transmitting the program codes to the processor;
the processor is configured to execute the custom credential circulation method of any one of claims 1-4 according to instructions in the program code.
10. A computer-readable storage medium for storing program code, the program code implementing the custom credential circulation method of any one of claims 1-4 when executed by a processor.
