when the data anchoring subsystem executes the timing detection task to perform corresponding detection on the anchoring node, if the change condition indicates that the corresponding source data has changed, the data anchoring subsystem sends a data update request to a data providing subsystem for providing the data, acquires changed data from the data providing subsystem for providing the data according to the data update request, and synchronously updates the cataloged data in the data encoding chain subsystem according to the changed data.
3. The system of claim 2, wherein the data-providing subsystem further comprises: a data encoding chain pre-exchange device, wherein,
the data coding chain channel pre-exchange device is used for managing resource cataloging information corresponding to data provided by the data providing subsystem and managing access authority of the data providing subsystem for blocks in the online block chain and preset data coding contracts and authorization contracts.
4. The system of claim 3, wherein,
the data encoding chain subsystem is further used for deploying the managed online blockchain into the data encoding chain pre-exchange equipment corresponding to the data providing subsystem with the access right.
5. The system of claim 4, wherein,
and the data anchoring subsystem adjusts the data coding membership relationship between the cataloged data and other data in the online block chain according to the resource cataloging information corresponding to the changed data after synchronously updating the cataloged data in the data coding chain subsystem according to the changed data.
6. The system of claim 5, wherein,
and the data anchoring subsystem adjusts the data coding membership relationship between the cataloged data and other data in the online blockchain according to the resource cataloging information corresponding to the changed data, and then synchronously updates the deployed online blockchain in the data coding chain prepositive exchange equipment according to the updated online blockchain.
7. A method of data interaction for a blockchain-based data interaction system as in any of claims 1-6, comprising:
receiving a link-in invitation message sent by a data platform;
packaging data to be uplinked into blocks, and acquiring resource cataloging information corresponding to the data to be uplinked, wherein the resource cataloging information is used for describing a data coding membership relationship between the data to be uplinked and cataloged data in an online blockchain; and
writing the block into an on-line blockchain;
determining a block chain node and acquiring initial configuration information corresponding to the block chain link node;
initializing and configuring the blockchain node according to the initial configuration information; and
after receiving the chain entry invitation message sent by the data platform, writing the block into a block chain corresponding to the block chain node after initialization configuration on the line;
managing a data scheduling flow between a data providing subsystem and the data platform through a switching front-end switching device, and managing an anchor node corresponding to the data providing subsystem, wherein when the data anchor subsystem executes a timing detection task, the anchor node is correspondingly detected, so that the change condition of source data corresponding to cataloged data in the online blockchain is detected;
and managing resource cataloging information corresponding to the data provided by the data providing subsystem through the data encoding chain prepositive switching equipment, and managing the access authority of the data providing subsystem for the blocks in the online block chain, and a preset data encoding contract and an authorization contract.
