In the embodiment of the present invention, the hash calculation may be performed to calculate the balance of the bill by using a hash algorithm.
Further, the hash algorithm comprises a sha256 algorithm and a ripemm 160 algorithm, and is a combination of the sha256 algorithm and the ripemm 160 algorithm, and a specific calculation formula is as follows:

For example, the preset associated nodes in the node topological relationship may include 7 nodes [ a0, a1, a2, A3, a4, and a5], and the nodes may have a connection relationship therebetween, where the connection relationship may be a TCP connection. For example, if the message to be broadcasted is sent from a0, the message to be broadcasted will be broadcasted to nodes [ a1, a2, A3], and after the a2 node receives the a0 message to be broadcasted, the message to be broadcasted will be broadcasted to [ a5, a4] in the same way, after the a5 receives the a2 message to be broadcasted, the message to be broadcasted will continue to be broadcasted to [ A3, a4] in the same time, and the broadcasting will continue until the broadcasting converges.

in this embodiment of the present invention, the node may be an account ID corresponding to a preset node according to a confirmation result returned by the broadcast, and the account ID may correspond to the temporary ID.
In this embodiment of the present invention, the performing consensus according to the confirmation result and the temporary ID includes:
counting the confirmation result and the temporary ID to obtain statistical data;
and selecting the data which is greater than a preset consensus threshold value in the statistical data as a consensus result.
For example, there are node X and node Y, the confirmation results returned by node X and node Y according to the broadcast are 3567 and 7872, respectively, the temporary ID is 3567, the frequency of 3567 is counted as 2, the frequency of 7872 is counted as 1, and it is assumed that the preset consensus threshold is the highest frequency, so it can be determined that 3567 is the consensus result.
And S8, confirming the consensus ID according to the consensus result, obtaining the consensus bill corresponding to the consensus ID, and synchronizing the consensus bill to a preset on-chain area.
In the embodiment of the present invention, the result of the consensus may be used as the consensus ID.
In the embodiment of the invention, if the consensus ID is the same as the temporary ID, the temporary bill can be determined as the consensus bill; if the consensus ID is different from the temporary ID, extracting a node corresponding to the consensus ID, and if the node returns a confirmation result and contains a bill, directly extracting the node; and if the node contains the bill when returning the confirmation result, sending a bill acquisition request to the node, and receiving information returned by the node according to the bill acquisition request to further acquire the consensus bill.
In the embodiment of the invention, after the consensus bill is obtained, the consensus bill can be synchronized to the block chain, so that the bill on the block chain has credibility.
According to the embodiment of the invention, the transaction information is directly processed, and the transaction queue is generated according to the transaction information, so that the transaction information is orderly executed, and the effective utilization of computer resources is improved; whether target transaction is executed is further judged by extracting target transaction information and calculating time difference; after the target transaction is executed, the temporary ID is generated according to the bill corresponding to the target transaction instead of directly linking the chain, so that the reliability of the bill on the chain is ensured; the temporary bill and the temporary ID are broadcasted, and the bill and the ID of the uplink are determined according to the information returned by other nodes, so that the accuracy of the bill data on the chain is ensured.

In the embodiments provided in the present invention, it should be understood that the disclosed apparatus, device and method can be implemented in other ways. For example, the above-described apparatus embodiments are merely illustrative, and for example, the division of the modules is only one logical functional division, and other divisions may be realized in practice.
The modules described as separate parts may or may not be physically separate, and parts displayed as modules may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment.
In addition, functional modules in the embodiments of the present invention may be integrated into one processing unit, or each unit may exist alone physically, or two or more units are integrated into one unit. The integrated unit can be realized in a form of hardware, or in a form of hardware plus a software functional module.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims shall not be construed as limiting the claim concerned.
The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product service layer, an application service layer, and the like.
Furthermore, it will be obvious that the term "comprising" does not exclude other elements or steps, and the singular does not exclude the plural. A plurality of units or means recited in the system claims may also be implemented by one unit or means in software or hardware. The terms first, second, etc. are used to denote names, but not any particular order.
Finally, it should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
