Content include deals match information and verification information；
Correspondingly, step S11 includes:
Step S20: when getting each Client-initiated transaction request, verification information is verified.
It should be noted that since transaction is to carry out between two or more users, and user sends out in itself
The preset condition that transaction is established, such as resource required for user and as cost branch are usually contained in the transaction request risen
Resource out, therefore transaction platform is when being collected into the transaction request that each user is initiated, it can be to the corresponding use of preset condition
Family is matched, and the target user in this step is the user with other user's successful match.
User in this step can be all from same block chain, can be from different blocks chain, that is to say, that transaction
It can establish, can also be established between the user in different blocks chain between the user in same block chain, it should be according to practical feelings
Depending on condition, it is not specifically limited herein.
In addition, including verification information in transaction request, the effect of verification information is the transaction for proving user and being initiated
The legitimacy of request.
Step S21: when verification information is without mistaking, corresponding user is obtained in target block chain according to deals match information
Target account data, and corresponding modification and synchronization between target account data are carried out, to complete the assets between target user
Transaction.
It is understood that the transaction request that this step is the target user that will be matched is sent in target block chain,
And then the legitimacy of target user's transaction request is verified by target block chain, when the transaction request of verifying target user is legal
Afterwards, the corresponding modification for meeting transaction request content is carried out to the account data of target user in target block chain, and will be after modification
Account data broadcast each block chain node into block chain to synchronize, and then complete the assets between target user and hand over
Easily.
It is emphasized that being that transaction other than block chain is flat for the matching of transaction request between user in the present embodiment
It is carried out in platform, and to the processing of transaction request is executed in block chain, due to including to prove to hand in transaction request
The easily verification information of request availability, therefore transaction platform can not distort transaction request, and then ensure that transaction in assets
Reliability.
Since transaction is content known in those skilled in the art between carrying out user by block chain, do not do herein
Excessive repeats.Present embodiment focuses on only in the processing for carrying out transaction request by block chain, and to transaction request
Matching by other than block chain transaction platform carry out, under present case to the matching of transaction request and processing by block chain
The case where completion, is compared, and the whole resource overhead of block chain is further saved.
In addition, as a preferred embodiment, in the corresponding modification of account data progress to target user and together
Before step, method further include:
Target account data setting data are locked.
Correspondingly, after the account data to target user carries out corresponding modification and synchronizes, method further include:
Operation is unlocked to target account data.
It should be noted that present embodiment to target block chain send target user transaction request after, pass through to
Target block chain initiates lock instruction, and control target block chain ensures the account data setting data lock of target user with this
Target block chain can not modify to the account data of target user because of other transaction requests, and then avoid because trading
Account data changes in journey, and the case where be unsatisfactory for preset condition in transaction request, ensure that trades goes on smoothly with this.Relatively
It answers, after the account data to target user carries out corresponding modification and synchronizes, in order to ensure target block chain is smoothly located
Other transaction requests are managed, need to initiate unlock instruction to target block chain, to control target block chain to the account of target user
User data is unlocked operation.This embodiment ensures that the account data and processing when target user initiates transaction request are traded
The consistency between account data when request, and then ensure going on smoothly for transaction.
In addition, as a preferred embodiment, verification information includes the digital signature generated according to transaction request.
It should be noted that the digital signature in present embodiment is generated according to transaction request is corresponding, it is specific raw

After transaction request, digital signature can be decrypted by the public key of target user first, generate original characteristic, and
Feature extraction is carried out to transaction request, obtains current characteristic, when original characteristic and current characteristic one
When cause, then assert that transaction request has availability, and then execute the processing to transaction request.In addition, the specific reality of feature extraction
Existing step is content known to those skilled in the art, and this will not be repeated here.It is generated after feature extraction due to transaction request
The data volume of characteristic is relatively small, and even if the difference between two transaction requests is smaller, also can be in characteristic
In embody biggish difference, therefore present embodiment opposite can reduce overall overhead simultaneously for digital signature as verification information
Increase accuracy.
In addition, as a preferred embodiment, deals match information is in advance by communicating with block platform chain node
Order processing server carries out matching generation according to the expensed asset quantity of each user and demand amount of assets.
It should be noted that the content of transaction request other than verification information, further includes asset addresses, expensed asset, branch
Amount of assets, demand assets, demand amount of assets and current transaction count out.Asset addresses are mentioned for characterizing target user
For specific storage address of the assets (expensed asset) in block chain；Expensed asset characterization is that target user initiates transaction when institute
Wish the assets of expenditure；What expensed asset quantity characterized is the quantity of expensed asset；Demand assets characterization is target user's hair
Play the assets of desired acquisition when transaction；What demand amount of assets characterized is the quantity of demand assets；Current transaction count characterization
Be current goal user initiate transaction whole number, in order to prevent because target user initiate two identical transaction
Request, and cause the generation of " honeysuckle ".
The content format of specific transaction request please refers to following table:
The content of transaction request can comprehensively record the transaction content of target user relatively in present embodiment, with this into
One step guarantees the preciseness and reliability of transaction.
Due to including expensed asset quantity and demand amount of assets in transaction request, and the essence traded is
By expensed asset switching requirement assets, therefore present embodiment is according to the expensed asset quantity and demand assets in transaction request
Quantity carries out the matching between user, such as in the transaction request of user t1, and the expensed asset quantity of expensed asset A is 20, demand
The quantity required of assets B is 30；And in the transaction request of user t2, the expensed asset quantity of expensed asset B is 30, demand assets
The quantity required of A is 20, since user t1 matches with the expensed asset of t2 with demand assets, by user t1 and user
The target user that t2 matches as transaction request.Present embodiment is by the expensed asset quantity and demand assets in transaction request
Quantity improves accuracy when choosing target user as matching foundation.
In addition, as a preferred embodiment, the quantity of Asset Type is greater than 1 in account data.
In view of a user often has a plurality of types of assets, if only recorded in account data a type of
Assets are difficult to ensure the diversity of transaction in assets, therefore in the present embodiment, and the quantity of Asset Type is greater than in account data
1, that is to say, that record has a plurality of types of assets of the user in the account data of user.
