the asset application terminal system searches all stock assets corresponding to the frozen asset ledger address and the managed asset type in the freezing instruction information in the asset ledger system according to the ledger record, and inquires transaction preorder assets of all stock asset information to serve as stock assets of assets to be frozen so as to obtain operation result information of the frozen assets;
and the assets to be frozen are determined according to all the down-link asset records in the down-link asset record index list in the down-link asset information.
3. A method of freezing a digital asset to be returned from a chain, comprising:
generating a downlink return asset freezing operation instruction with an asset hosting system signature based on a downlink return request instruction with a user terminal system and an asset hosting system double signature;
verifying the down-link return asset freezing operation instruction; after the verification is passed, freezing the digital assets to be returned from the off-link according to the off-link returned asset freezing operation instruction, and recording frozen asset transactions and result assets;
searching for and acquiring operation result information of the frozen asset, and verifying the operation result information of the frozen asset; after the verification is passed, determining that the freezing of the digital assets to be returned from the downlink is finished;
the downlink return request instruction comprises the following steps: returning user information and downlink asset information; the down-link return asset freezing operation instruction comprises the following steps: freezing instruction information, namely a downlink return request instruction with double signatures of a user terminal system and an asset hosting system; the frozen asset operation result information includes: freezing an account book address of the asset, freezing an asset type of the asset, and freezing asset information;
the asset account book system verifies the down-link return asset freezing operation instruction, and the verification method comprises the following steps: the on-chain consensus node of the asset account book system independently verifies the signature of the down-chain return asset freezing operation instruction and the signature of the down-chain return request instruction; after the signature verification is confirmed to pass, verifying the freezing instruction information in the down-link return asset freezing operation instruction according to the following method: verifying whether the asset class of the result assets of the frozen asset transaction and the residual asset transaction in the freezing instruction information is the same as the managed asset class in the downlink asset information; verifying whether the sum of the assets in the freezing instruction information is the same as the quantity of the downlink assets in the downlink asset information or not; if the verification result information is the same as the verification result information, returning verification passing result information to the asset account book system;
the asset application terminal system verifies the frozen asset operation result information, and the verification comprises the following steps: verifying whether the frozen assets in the frozen asset information are the same as the assets to be frozen or not; verifying whether the number of the frozen assets in the frozen asset information is the same as the number of the downlink assets in the downlink asset information; and verifying whether the frozen asset record index and the residual asset record index in the frozen asset information conform to the frozen asset transaction content and the residual asset transaction content in the frozen instruction information; and if so, returning the result information of passing the verification to the asset application terminal system.
4. The method of claim 3, wherein finding frozen asset operation result information comprises:
searching all stock assets corresponding to the frozen asset account book address and the managed asset type in the freezing instruction information according to the account book record, and inquiring transaction preorder assets of all the stock asset information to serve as stock assets of assets to be frozen so as to obtain operation result information of the frozen assets;
and the assets to be frozen are determined according to all the down-link asset records in the down-link asset record index list in the down-link asset information.
