5. A blockchain tie-out system according to claim 1, further comprising a business data processing unit in communication with said data processing unit;
and the business data processing unit is used for processing the business reconciliation data according to a preset reconciliation rule to obtain the business data to be stored in the account book and sending the business data to the data processing unit.
6. A blockchain reconciliation method comprising:
acquiring data packet hash on a block chain, wherein the data packet hash carries identity identification information of a corresponding alliance member node unit;
when the identity identification information is judged to pass the matching, acquiring a data packet corresponding to the hash of the data packet from an enterprise database of the alliance member node unit;
when judging that the data packet corresponding to the data packet hash does not exist in the enterprise database, sending a data packet synchronization request corresponding to the data packet hash to a core member node unit so as to acquire the data packet corresponding to the data packet hash from a backup database of the core member node unit;
and carrying out reconciliation processing on the data packet corresponding to the data packet hash and the data packet hash on the block chain.
7. A computer arrangement comprising a memory and a processor, the memory having stored therein a computer program that, when executed by the processor, causes the processor to carry out the steps of the blockchain reconciliation method of claim 6.
8. A computer-readable storage medium, having stored thereon a computer program which, when executed by a processor, causes the processor to carry out the steps of the blockchain tie-out method of claim 6.
