In the case where trusted node, determine in the block of second central node generation through the area of the verifying of first central node
The current quantity of block.
Step S32 determines the corresponding pass that the current quantity is hit from the corresponding relationship that the trust evidence list prestores
System, determines the first ratio recorded in the corresponding relationship of the hit, and to the transaction of the first ratio described in the new block into
Row verifying.
Wherein, the current quantity can serve as the above-mentioned number of blocks formerly verified, and first ratio can fill
When the above-mentioned ratio for needing to verify corresponding with number of blocks that is formerly verifying.
Optionally, in the present embodiment, first central node is according to the trust evidence table being locally stored to described new
The step of block is really weighed may include sub-step shown in Fig. 4.
Step S41, first central node is in the feelings that second central node is the indirect trusted node of this node
Under condition, the mutual trust rate currently reached in the block of the second central node generation with first central node is determined.
Step S42 determines the correspondence that the mutual trust rate is hit from the corresponding relationship that the trust evidence list prestores
Relationship determines the second ratio recorded in the corresponding relationship of the hit, and the transaction to the second ratio described in the new block
It is verified.
Wherein, the mutual trust rate currently reached can serve as it is above-mentioned reach mutual trust rate, second ratio
Example, which can be served as, reaches that mutual trust rate is corresponding to need the ratio verified with described.
Based on description above, since the random period that each central node waits is different, each central node can
The new block generated by another central node can be received, may include the part transaction thing in trading pit in the new block

In a common recognition period, each cluster in hierarchical block chain network 10 can only allow to generate a new block.Wherein, described total
The maximum value for knowing the period can be defaulted as 5 minutes (that is: the 1/2 of the bit coin digging mine period).The minimum value in the common recognition period can
Twice for thinking the maximum end-to-end delay duration between the node in the hierarchical block chain network, so, it can be ensured that have foot
The enough time propagates the new block of other central nodes generation.
In particular, the neighbor node of the central node can be right in order to avoid central node prompts the waiting time insufficient always
This node is monitored in the frequency that waiting time generates new block, once the new district number of blocks for monitoring generation is more than threshold value,
Then the central node can abandon the new block that the neighbor node generates.
Optionally, in the present embodiment, the case where being excessively delayed may also occur in central node.Based on this, the present embodiment
The method of commerce of offer can with the following steps are included:
Delay duration between any two node reaches the case where preset quantity times of preset block chain billing cycle
Under, the multiple limited resources node in the limited resources layer re-starts cluster.

And it is sent to the control equipment of the extended resources layer；
The control equipment of the extended resources layer carries out consistency checking to the new block, if by the consistency checking,
Then the second block chained list of the extended resources layer is updated, and is broadcasted to each central node of the limited resources layer
The new block.
9. according to the method described in claim 8, it is characterized in that, the method also includes:
The first central node that the new block is received in the limited resources layer is used for according to the trust evidence being locally stored
Table really weighs the new block；
Wherein, record has the direct trusted node of the central node and trusts section indirectly in the trust evidence table of each central node
Point, at least one block that the direct trusted node generates pass through the verifying of the central node, and the indirect trusted node is raw
At the verifying that passes through any direct trusted node of the central node of at least one block.
10. according to the method described in claim 9, it is characterized in that, first central node is according to the trust being locally stored
Evidence table really weighs the new block, comprising:
In the case where generating the second central node of the new block is the direct trusted node of this node, determine this in second
Pass through the current quantity of the block of the verifying of first central node in the block that heart node generates；From the trust evidence table
The corresponding relationship that current quantity hit is determined in the corresponding relationship prestored, determines first recorded in the corresponding relationship of the hit
Ratio, and the transaction of the first ratio described in the new block is verified；
In the case where second central node is the indirect trusted node of this node, determine that second central node generates
Block in the mutual trust rate currently reached with first central node；From the corresponding pass that the trust evidence list prestores
The corresponding relationship that mutual trust rate hit is determined in system, determines the second ratio recorded in the corresponding relationship of the hit, and right
The transaction of second ratio described in the new block is verified.
