When a certain node of the blockchain system initiates a data reading request, the node firstly broadcasts the data reading request to all the blocks 10 of the blockchain system, and after all the blocks 10 are judged by a consensus mechanism, a storage address pointer of target data is obtained, wherein the consensus mechanism is judged to be the prior art and is not described herein. The node initiating the data reading request sends the consensus storage address pointer to the authentication module 20, after receiving the consensus storage address pointer, the authentication module 20 confirms whether a record of the consensus storage address pointer exists in a history record, after authentication, the consensus storage address pointer information is forwarded to the logic storage management module 30, the logic storage management module 30 reads service and transaction information data from all authenticated logic storage modules 40 according to the address and sends the read data to the authentication module 20, the authentication module 20 performs consensus judgment on the received data, and sends consensus result data to the node initiating the request.

All nodes find the storage address pointers of the target service data from the blocks of the nodes, then judge the storage address pointers through a consensus mechanism, for example, the invention adopts a 51% principle, namely n nodes vote the storage address pointers of the target service data, and when the storage address pointers of the target service data in more than 51% multiplied by n nodes are consistent, the storage address pointers of the target service data are considered as final storage address pointers of the target data and are recorded as the final storage address pointers of the target data

8. The method for fast storing of a blockchain data storage device according to claim 7, wherein the processing procedure of the step S3 includes the steps of:
when the node j initiates a data storage request, the logic storage management module (30) of the node j screens out the logic storage modules (40) meeting the conditions according to the step S2 to form a pre-selected storage module set for storing the service or transaction data of the node j
And the IP address and the data address of the logical storage module (40) meeting the conditions and the data content Hash value in the logical storage module (40) are sent to an authentication module (20), on one hand, the authentication module (20) verifies the information of the preselected storage module set according to the received data content Hash value in the logical storage module (40), and sends the IP address and the data address of the logical storage module (40) passing the verification and the Hash value of the data content to a block (10), and the block (10) stores the received data to a block (10)The IP address, the data address and the Hash value of the data content of the storage module (40) are stored in a block (10) to be used as a pointer of a service data or transaction data storage address, and the pointer information of the service data or transaction data storage address is broadcasted to the blocks (10) of all nodes in the block chain system for storage; on the other hand, the information of the verified logic storage module (40) is sent to the logic storage management module (30), and the logic storage management module (30) stores the business or transaction data to all the verified logic storage modules
In the method, each logic storage module (40) in c logic storage modules (40) in the block chain system has one copy of service data requested to be stored by a node j, so that one-time service data storage is completed.
9. The method for fast storing of a blockchain data storage device according to claim 8, wherein the processing procedure of the step S4 includes the steps of:
when a node w of a block chain system initiates a data reading request, the requested data is called target data, the node w firstly broadcasts the target data reading request to all blocks (10) of the block chain system, all the blocks (10) inquire self service data or a transaction data storage address pointer recording table, and after the inquired service data or transaction data storage address pointer recording is judged by a consensus mechanism, a consensus storage address pointer of the target data is obtained; the node w sends the consensus storage address pointer to an authentication module (20) of the node w, after receiving the consensus storage address pointer, the authentication module (20) of the node w confirms whether a record of the consensus storage address pointer exists in a historical record, if the record of the consensus storage address pointer is not inquired in the historical record, the authentication is regarded as failed, and the data reading request process is terminated; if the authentication is passed, the consensus storage address pointer information is forwarded to the logic storage management module (30), the logic storage management module (30) reads service and transaction information data from all authenticated logic storage modules (40) according to the address pointer, the read data is sent to the authentication module (20), the authentication module (20) performs consensus judgment on the received data, and sends consensus result data to the node w which initiates the request.
