block chain core service module for IPFS configuration: is an intelligent contract for configuring certified upper chains.
Preferably, the data storage module comprises the following steps:
s1: creating a data fragment: the system divides the data into very small pieces;
s2: and (3) encryption and fragmentation: the storage system is to encrypt each data slice on the local system;
s3: a hash is generated for each slice: the system generates a unique hash according to the secret key;
s4: and copying the fragments: the system copies all fragments to prevent data loss;
s5: distributing the copied fragments: distributing the copied fragments to each storage node;
s6: and (4) recording the transaction record to account: all things in all ledgers are recorded and automatically synchronized between nodes.
Preferably, the information sharing module is an intelligent contract which is required by the data owner to configure access control and an intelligent contract which promotes settlement.
