Address date, can be storage address date, and the access as the secondary service content links.
In S312, the block chain exports the access link and access public key.
In the embodiment of the present application, in block chain, a block chain can be opened for each target object, for the mesh
Each service data of mark object can be linked in upper a behavioral data block of the target object.New block can be added
Once entering to record finally, the behavioral data of target object is written into block chain, just again it cannot change and delete.Each area
Block has recorded all events occurred before it is created.The block structure of one block is as follows:
As shown in figure 4, each block is a transaction, after the transaction reached by scheduled mechanism, area can be written to
Between block, each block content contain (block ID, block father ID, chaincodeID (index value), Transaction Information, etc.).
The mark of each block is chaincodeID value, and chaincodeID value is the legal registration code of traffic contract, it was demonstrated that this area
Block transaction is after being successfully processed by current scheduled mechanism, to be written among block chain.
Wherein, block chain node and block chain network building, can for example using certain base of company operating agency as minimum node,
One or more branch companies participate in insurance transaction block chain network building.In the embodiment of the present application, the data structure of block can
