24. device according to claim 23, it is characterised in that the 3rd authentication unit includes：3rd calculates son list Member, the first judgment sub-unit and the 3rd checking subelement；

3rd computation subunit, the hash value for calculating first block in the branched chain；

First judgment sub-unit, for judging that the 3rd computation subunit calculates first block in the branched chain Hash value and next block in previous block hash value it is whether identical；

The 3rd checking subelement, for judging that the 3rd computation subunit calculating is described when first judgment sub-unit When the hash value of first block in branched chain is identical with the previous block hash value in next block, the branch is verified Whether next block on chain meets the agreement of the branched chain；

Second judgment sub-unit, for judging whether the timestamp of each block in the branched chain meets branched chain agreement The form of defined timestamp；

The addition subelement, for judging that the timestamp of each block in the branched chain is equal when second judgment sub-unit When meeting the form of timestamp as defined in branched chain agreement, new area is added in the branched chain according to the agreement of branched chain Block.
