6. A blockchain-based heterogeneous asset transaction system, comprising:
a conversion module, wherein the conversion module is configured to convert a unique digital certificate for associating a user asset in a federation chain to a non-homogeneous certificate corresponding to the unique digital certificate issued on a public/foreign chain according to a preset cross-chain mapping intelligent contract;
an issuance recording module, wherein the issuance module is communicatively coupled to the conversion module, wherein the issuance module is configured to issue a non-reputational voucher corresponding to the non-reputational voucher and to record ownership of the non-reputational voucher on the public/foreign link, wherein the issuance recording module further records a request for a change in ownership of the non-reputational voucher corresponding to the asset data of the current user on the public/foreign link; and
a modification determining module, wherein the modification module is communicatively connected to the issue recording module, wherein the modification module is configured to determine a modification request corresponding to the unique digital certificate to be modified according to the request related to the ownership change and the cross-chain mapping intelligent contract, and modify the asset data and the intelligent contract of the current user in the federation chain according to the modification request.
7. The blockchain-based heterogeneous asset transaction system of claim 6, wherein the issue record module is further configured to receive an unlock request from the changed owner to unlock the user's asset status.
8. The blockchain-based heterogeneous asset transaction system of claim 7, further comprising a verification module, wherein the verification module is communicatively coupled to the transformation module, the issue recording module, and the decision modification module, wherein the decision modification module applies for an unlock request to unlock the user's asset status by a changed owner through a blockchain verification.
9. The blockchain-based heterogeneous asset transaction system of claim 8, wherein the verification module is configured to verify asset data and intelligent contracts of the current user by the blocks in the federation chain, and when the asset data and intelligent contracts of the current user are verified, the decision modification module modifies the asset state of the current user in the federation chain to a locked state by the intelligent contracts and generates a unique digital voucher corresponding to the asset of the previous user in the federation chain.
10. A computer apparatus comprising one or more processors; a memory; and one or more computer programs, wherein the one or more computer programs are stored in the memory, the one or more computer programs comprising instructions which, when executed by the apparatus, cause the apparatus to perform the method of any of claims 1 to 5.
