Fig. 1 illustrates for the architectural framework of the asset data processing system provided in an embodiment of the present invention based on block chain technology
Figure, as shown in figure 1, the asset data processing system based on block chain technology that the present embodiment is provided includes：One main chain and root
The a plurality of side chain formed according to region division, wherein main chain and side chain are the block chain comprising multiple blocks.
In actual applications, the side chain is used to handle the asset data in the corresponding region of the side chain, and
Asset data processing information is reported by the cycle of T to the main chain, and, the new district block message generation for downloading the main chain is described
The wound generation block in side chain next cycle, wherein, the new block of the main chain is the current week reported in the main chain to the side chain
Generated after the asset data processing information statistics of phase；The main chain is used for the asset data between different zones
Reason.
Asset data processing system provided in an embodiment of the present invention is a kind of complicated area based on block chain technique construction
Block chain network, we term it region chain network, region chain network is made up of a transaction main chain and some transaction side chains.
Main chain is as the core of whole region chain network, transaction (asset data processing information) timing that all side chains can occur side chain
Main chain is reported, is counted by main chain and is recorded the whole of the whole network and merchandise.Side chain comes according to actual region zones or application demand
Set up, it is necessary to region in formation one side chain.For example, CHINESE REGION possesses a Chinese chain, in the user of China, if not
The account trading with exterior domain is needed, as long as using this Chinese chain of one's respective area.
It should be noted that can continue to divide thinner region below Chinese chain, secondary side chain is formed.It is right in theory
Do not limited in the division in region and rank.If needing a single side chain in local area, it can realize.
General one region of transaction side chain correspondence, therefore transaction side chain can have one, it is possibility to have it is a plurality of.Typically
Certainly there is a transaction main chain, but the quantity of transaction side chain is not fixed then, can there is a plurality of or no transaction side chain.If only
A unique transaction side chain, then this transaction side chain be also transaction main chain, therefore transaction main chain certainly exist, now quite
In no transaction side chain, its trade management is equivalent to existing single block catenary system.
When side chain quantity of merchandising is more than two, Transaction Information (the asset data processing reported by this two transaction side chains
Information) regeneration transaction main chain.
Transaction main chain block is periodically generated, and the Transaction Information (money that each transaction side chain is reported is record in transaction main chain block
Produce data processing of information), generations of transaction main chain block is namely based on each Transaction Information for reporting of side chain of merchandising (at asset data
Manage information) complete, the transaction main chain of system is unique.
Merchandise main chain block the generation cycle, can with every transaction side chain to transaction main chain report Transaction Information (assets
Data processing of information) cycle phase with (the generation cycle for main chain block of merchandising is T), can also be more than every transaction side chain to
Transaction main chain reports the cycle (the generation cycle of transaction main chain block is more than T) of Transaction Information (asset data processing information), no
Invalid main chain block may then be produced.Generally, the generation cycle of transaction main chain block is more than T, when late this section
Between can as main chain verify node carry out o f chain checking time.
Side chain merchandise using identical common recognition mechanism, i.e., (Delegated Proof-of- are all proved using mandate equity
Stake, abbreviation DPOS) mechanism.Every transaction side chain has the trustee of oneself, and oneself trustee is determined by region chain network.
On the one hand transaction main chain trustee is selected by main chain node free voting, and on the one hand each transaction side chain must be in transaction main chain
It is upper to contain at least one trustee, to ensure the just and fair of main chain of merchandising.
Every transaction side chain data can be updated by the cycle of T, for any bar transaction side chain, specific renewal process
For：
1) when transaction side chain has arrived the periodic report time, the Transaction Information of trustee's packing epicycle of block is gone out by the round
(asset data processing information), and block information (such as the hash value informations including block) all during week and assets
Redemption request reports transaction main chain；
2) transaction main chain epicycle goes out the trustee of block, receives Transaction Information (the asset data processing that transaction side chain is reported
Information), data statistics is carried out, assets exchange trading is mainly counted, and all information packages are entered main chain block；
3) after main chain of merchandising completes data statistics and information package, transaction side chain next round goes out block trustee, will be synchronous
Transaction main chain information, is handled and is verified, generate the wound generation block in the transaction side chain new cycle.
Block 1 ' such as the corresponding transaction side chain A in a-quadrant in Fig. 1 will be generated by the data of the block 5 of transaction main chain, as
The wound generation block in transaction side chain A new cycles.Similarly, the corresponding transaction side chain chain B in B regions block 1 ' is by the block of transaction main chain
6 data generation, is used as the wound generation block in transaction side chain B new cycles.
It should be noted that every transaction side chain data can be all updated by the cycle of T.That is, every transaction
The report cycle of side chain is identical, because the initial time of every transaction side chain is differed, thus every transaction side chain on give the correct time
Between and it is different.Consequently, it is possible to which the reported data of different transaction side chains is handled in the different blocks of transaction main chain simultaneously, it is to avoid locate
The data of a plurality of transaction side chain of reason, reduce the burden of transaction main chain.
It is noted that transaction side chain is carrying out periodic report until generating the wound generation block phase in new cycle to transaction main chain
Between, it is impossible to confirm transaction.Between this, the Transaction Information in current period can also be reported to transaction main chain according to transaction side chain
The trading halt time is set to time of new cycle wound generation block is generated for the transaction side chain, can not be carried out within the trading halt time
Asset data processing.Or, can be according to the characteristics of different zones, when setting trading halt for the corresponding transaction side chain in the region
Between.
It is further to note that whole region chain network uses identical fictitious assets, for example, it is properly termed as assets X.
Assets X constant numbers, but X is by with special flag attribute.Below with the corresponding transaction side in a-quadrant in Fig. 1 and B regions
It is illustrative exemplified by chain A and transaction side chain B.
Whole region chain network has two transaction side chains A and B, then X is classified into X_A, X_B and X ', i.e. X=X_A+
X_B+X’.Wherein, X_A represents the amount of money that user can use in the corresponding transaction side chain A in a-quadrant, and X_B represents user can be
The amount of money that the corresponding transaction side chain B in B regions is used, X ' represents the amount of money that user can use in transaction main chain.X_A, X_B and X '
It directly can mutually exchange, exchange and carried out when each transaction side chain reports Transaction Information to transaction main chain every time.X total amounts
It is constant, so X_A, X_B and X ' all it is assets X, their value is identical.
Transaction of the user in the A of region, is carried out using X_A, is confirmed by transaction side chain A and is verified；Friendship in the B of region
Easily carried out using X_B, confirmed by transaction side chain B and verified.Settlement of transactions in regional, it is not necessary to which main chain is participated in, but
Transaction side chain reports main chain of being merchandised when Transaction Information to verify and count to transaction main chain every time, and user is without being concerned about.Respectively
As long as respectively transaction side chain oneself confirms that transaction is exactly credible, reliable to the settlement of transactions in individual region.If user need into
The trans-regional transaction of row, user needs to use X ' to initiate transaction on transaction main chain, and by merchandising, main chain carries out different zones user
Between settlement of transactions.
For example, for example：
User a remaining sum 100X, wherein 30X_A, 0X_B, 70X '；
User b remaining sum 50X, wherein 20X_A, 30X_B, 0X '；
User c remaining sum 60X, wherein 0X_A, 10X_B, 50X '；
It can be seen that user a is the user of a-quadrant, user b has transaction in a-quadrant and B regions, and user c is B regions
User.
Scene 1：Customer transaction in same area
User a and b are traded in a-quadrant using transaction side chain A, and the user a 10X that transfer accounts give user b, are user in fact
The a 10X_A that transfer accounts give user b, and user a remaining sums will become 90X=20X_A+0X_B+70X '；User b remaining sum will be changed into 60X=
30X_A+30X_B+0X’.Similarly, user b and c merchandises in B regions directly to be carried out using transaction side chain B, by each
Transferred accounts from the remaining sum in B regions.
Scene 2：The customer transaction of different zones
User a and c merchandise, it is necessary to be traded clearing by merchandising main chain.So user a transfers accounts, 10X gives user c,
It is that user a transfers accounts 10X ' to user c in fact.User a remaining sum becomes 90X=30X_A+0X_B+60X '；User c remaining sum becomes
Into 70X=0X_A+10X_B+60X '.
Scene 3：Same user account assets are exchanged
When user a transfers accounts 40X to user b, find Sorry, your ticket has not enough value because X_A can only be circulated in a-quadrant, this when
Standby family a can be selected to turn X ' to user b on transaction main chain, or the X ' of oneself is exchanged into after X_A, then in a-quadrant
It is interior to be transferred accounts by the side chain A that merchandises.Exchange operation is special operation, also in transaction side chain A on initiate exchange trading,
But this exchange trading is only at the end of current period, transaction main chain, main chain to be transacted is reported just to be come into force after confirming.
, it is necessary to the regular hour just as bank's foreign exchange settlement.
The asset data processing system based on block chain technology that the present invention is provided block catenary system more single than existing tradition is more
Efficiently, it is possible to achieve block chain is localized, personalized extension, enhances the ease for use of block chain, improves the performance of block chain.
It is in particular in：
1) than single block catenary system efficiency high, utilization rate is high.All transaction need not have a chain to undertake, reduction
Node goes out the pressure of block, solves the defect that the bottleneck and storage resource of the transaction of block chain are wasted.
2) node resource is more reasonably make use of, for most transaction, it is not necessary to trans-regional, as long as being carried out in region
Checking confirms just can be with.Different zones are not influenceed mutually with different block chains.The user of transaction side chain, it is only necessary to same
The one's respective area correspondence transaction side chain block walked in a cycle just can be with without resynchronizing other redundancy blocks.
3) regional assets easily demand had both been met, a kind of actual in fact and simply assets, the whole network is general, convenient
Exchanged in free net, allow user to need which kind of transaction all easily convenient.
