Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
The block chain (Blockchain) is a distributed database system participated by nodes, and has the characteristics of being unchangeable, being not forged and also being understood as an account book system (hedger). It is an important concept of bitcoin, a copy of the complete bitcoin block chain, which records every transaction of its token (token). With this information we can find the value that each address has at any point in the history.
A block chain is composed of a string of data blocks generated by cryptography, each block containing the hash value (hash) of the previous block, and is linked to the current block starting from a starting block (genesis block) to form the block chain. Each chunk is guaranteed to be generated after the previous chunk in chronological order, otherwise the hash value of the previous chunk is unknown, and these features make repeated payout (double-spreading) of bitcoins very difficult. The blockchain is a core innovation of the bitcoin.
Fig. 1 is a schematic architecture diagram of an asset data processing system based on a blockchain technology according to an embodiment of the present invention, and as shown in fig. 1, the asset data processing system based on a blockchain technology according to the present embodiment includes: the main chain and the side chains are formed according to regional division, wherein the main chain and the side chains are block chains comprising a plurality of blocks.
In practical application, the side chain is configured to process asset data in a region corresponding to the side chain, report asset data processing information to the main chain in a period of T, and download new block information of the main chain to generate an creation block of a next period of the side chain, where the new block of the main chain is generated after statistics of asset data processing information of a current period reported by the main chain to the side chain; the main chain is used for processing the asset data between different regions.
The asset data processing system provided by the embodiment of the invention is a complex block chain network constructed based on a block chain technology, which is called as a regional chain network, and the regional chain network consists of a transaction main chain and a plurality of transaction side chains. The main chain is used as the core of the whole area chain network, all the side chains can report the transactions (asset data processing information) generated by the side chains to the main chain at regular time, and the main chain counts and records all the transactions of the whole network. The side chains are established according to the actual geographical division or application requirements, and a side chain is formed in a required area. For example, a china region has a china chain, and a user in china only needs to use the china chain in this region if the user does not need to deal with an account in a foreign region.
It should be noted that, under the chinese chain, a finer region may be further divided to form a secondary side chain. There is theoretically no limitation on the division and the level of the region. This can be achieved if a separate side chain is required in the area.
Generally, one transaction side chain corresponds to one region, so that there may be one transaction side chain or a plurality of transaction side chains. Generally, there is a main trade chain, but the number of trade side chains is not fixed, and there may be more or no trade side chains. If only one transaction side chain is provided, the transaction side chain is also a transaction main chain, so that the transaction main chain is necessarily present, namely no transaction side chain is provided, and the transaction management is equivalent to the existing single blockchain system.
When the number of the transaction side chains exceeds two, the transaction information (asset data processing information) reported by the two transaction side chains is regenerated into a transaction main chain.
The transaction main chain block is generated regularly, transaction information (asset data processing information) reported by each transaction side chain is recorded in the transaction main chain block, the generation of the transaction main chain block is completed based on the transaction information (asset data processing information) reported by each transaction side chain, and the transaction main chain of the system is unique.
The generation period of the transaction main chain block may be the same as the period of reporting the transaction information (asset data processing information) to the transaction main chain by each transaction side chain (that is, the generation period of the transaction main chain block is T), or may be greater than the period of reporting the transaction information (asset data processing information) to the transaction main chain by each transaction side chain (the generation period of the transaction main chain block is greater than T), otherwise, an invalid main chain block may be generated. Generally, the generation period of the transaction main chain block is greater than T, and the later time can be used as the time for the main chain verification node to perform distributed block chain verification.
The transaction side chain adopts the same consensus mechanism, namely, adopts a released Proof of possession (DPOS for short) mechanism. Each side chain of the transaction has its own consignee, which is determined by the regional chain network itself. On one hand, the transaction main chain acceptors are selected by free voting of main chain nodes, and on the other hand, each transaction side chain must contain at least one acceptors on the transaction main chain to ensure the fairness and fairness of the transaction main chain.
Each transaction side chain data is updated by taking T as a period, and for any transaction side chain, the specific updating process is as follows:
1) when the transaction side chain reaches the period reporting time, the trustee who goes out blocks in the round packs the transaction information (asset data processing information) of the round, and reports all block information (for example, hash value information of blocks) and asset conversion requests in the period to the transaction main chain;
2) the trustee who has the transaction main chain originally takes the turn out of the block receives the transaction information (asset data processing information) reported by the transaction side chain, performs data statistics, mainly counts asset exchange transactions, and packs all the information into a main chain block;
3) and after the main transaction chain completes data statistics and information packaging, the next round of the transaction chain goes out of the trustee, and the synchronous main transaction chain information is processed and verified to generate the new period of the creation block of the transaction chain.
The block 1' of the transaction side chain a corresponding to the a region in fig. 1 will be generated from the data of the block 5 of the transaction main chain as the creation block of the new cycle of the transaction side chain a. Similarly, the block 1' of the transaction side chain B corresponding to the B region is generated from the data of the block 6 of the transaction main chain, and is used as the creation block of the new cycle of the transaction side chain B.
It should be noted that each transaction side chain data is updated with a period of T. That is, the reporting period of each transaction side chain is the same, and the reporting time of each transaction side chain is different because the initial time of each transaction side chain is different. Therefore, the reported data of different transaction side chains are processed in different blocks of the transaction main chain, so that the data of a plurality of transaction side chains are prevented from being processed simultaneously, and the burden of the transaction main chain is reduced.
It is worth mentioning that the transaction side chain will not be able to confirm the transaction during the period of reporting to the transaction main chain until the new period of creating blocks is generated. In this case, the transaction suspension time can be set for the transaction side chain according to the time from the transaction side chain reporting the transaction information in the current period to the transaction main chain generating the new period creation block, and the asset data processing cannot be performed within the transaction suspension time. Alternatively, the transaction suspension time can be set for the transaction side chain corresponding to the region according to the characteristics of the different regions.
It should be noted that the entire area chain network uses the same virtual asset, which may be referred to as asset X, for example. The asset X number is constant, but X will carry a special tag attribute. The following description will be made by taking the trade side chain a and the trade side chain B corresponding to the region a and the region B in fig. 1 as an example.
The entire area chain network shares two transaction side chains a and B, then X will be divided into X _ a, X _ B and X ', i.e. X ═ X _ a + X _ B + X'. Wherein, X _ A represents the amount of money that the user can use in the transaction side chain A corresponding to the area A, X _ B represents the amount of money that the user can use in the transaction side chain B corresponding to the area B, and X' represents the amount of money that the user can use in the transaction main chain. X _ A, X _ B and X' may be directly exchanged with each other, the exchange being performed each time the transaction side chain reports transaction information to the transaction main chain. The total amount of X is constant, so X _ A, X _ B and X' are both assets X, their value is the same.
The user's transaction in area a, using X _ a, is confirmed and verified by transaction side chain a; the transaction within zone B is carried out using X _ B, confirmed and verified by transaction side chain B. The main chain is not needed to participate in transaction settlement in each region, but the main chain can be verified and counted when the transaction side chain reports transaction information to the main chain every time, and a user does not need to care about the main chain. The trade settlement in each region is credible and reliable as long as each trade side chain confirms the trade. If the user needs to carry out cross-regional transaction, the user needs to use X' to initiate transaction on a transaction main chain, and transaction settlement between users in different regions is carried out through the transaction main chain.
For example, such as:
user a balance 100X, where 30X _ a, 0X _ B, 70X';
user B balance 50X, where 20X _ a, 30X _ B, 0X';
user c balance 60X, where 0X _ a, 10X _ B, 50X';
it can be seen that user a is a user in area a, user B has transactions in area a and area B, and user c is only a user in area B.
Scene 1: user transactions within the same region
Users a and B trade in the area A by using a trade side chain A, wherein the user a transfers 10X to the user B, in fact, the user a transfers 10X _ A to the user B, and the balance of the user a is changed into 90X which is 20X _ A +0X _ B + 70X'; the balance of subscriber B will become 60X-30X _ a +30X _ B + 0X'. Similarly, the transactions of the users B and c in the area B can also be directly carried out by using the transaction side chain B, and the account transfer is carried out through the balance of the respective area B.
Scene 2: user transactions in different areas
Users a and c trade, and trade settlement is needed through the trade main chain. So user a transfers 10X to user c, which is user a transferring 10X' to user c. The balance of user a becomes 90X-30X _ a +0X _ B + 60X'; the balance of the user c becomes 70X ═ 0X _ a +10X _ B + 60X'.
Scene 3: same user account asset redemption
When the user a transfers 40X to the user b, the balance is found to be insufficient because only X _ A can circulate in the area A, and at this time, the user a can choose to transfer X 'to the user b on a transaction main chain or transfer the self X' to the user b through the transaction side chain A after exchanging the X _ A, and then transfer the account in the area A. The exchange operation is a special operation, and the exchange transaction is initiated on the transaction side chain A, but the exchange transaction is reported to the transaction main chain only when the current period is finished, and the exchange transaction takes effect after the transaction main chain is confirmed. As with bank foreign exchange settlement, a certain amount of time is required.
Compared with the traditional single blockchain system, the asset data processing system based on the blockchain technology provided by the invention is more efficient, can realize regionalization and personalized expansion of the blockchain, enhances the usability of the blockchain and improves the performance of the blockchain. The concrete points are as follows:
1) compared with a single block chain system, the system has high efficiency and high utilization rate. All transactions do not need to be borne by a chain, the pressure of node block output is reduced, and the defects of bottleneck of block chain transaction and waste of storage resources are overcome.
2) Node resources are utilized more reasonably, and most of transactions do not need to cross regions, and only verification and confirmation are carried out in the regions. Different areas use different block chains, and have no influence on each other. The user of the transaction side chain only needs to synchronize the region corresponding to the transaction side chain block in one period, and does not need to synchronize other redundant blocks.
3) The requirement of regional assets is met, and the system is really an asset, is universal in the whole network and convenient and free to exchange in the network, so that a user can conveniently and rapidly transact any kind of needed assets.
