Method may include: the finance change transaction of S100, identification user's transmission；Wherein, the content of finance change transaction includes initiating
Person, change Finance users need to change finance and the financial value of corresponding change.
It, can be right since block chain financial payments management method provided in this embodiment requires Deep integrating into block chain
Block chain carries out comprehensive financial payments control, is only capable of realizing block chain in intelligent contract level in the prior art to overcome
Financial payments management (can not carry out permission lower than intelligent contract level, such as transmission transaction, acquisition block chain state etc.
Control) either rely on outside plant.Therefore the present embodiment increases a kind of i.e. finance change of new type of transaction in block chain
More trade, the operation corresponding to financial payments.When block chain receives the change request of finance, corresponding finance can be generated and become
More trade.The finance.
Change transaction can be similar with general transaction, will record after execution within a block i.e. by the change of payment information
Historical record is in block chain, to audit.Receipt (Receipt) can be generated as general transaction simultaneously, so as to user
Can according to receipt determine finance change transaction whether succeed, i.e., the receipt can be used family recognize in time finance change transaction
Executive condition.The present embodiment by finance change transaction realize financial payments information change operation include: increase, deletion,
Modification etc..The permission being related in embodiment may include financial payments management, deployment contract and send general transaction, practical
It is not limited to above-mentioned three kinds, it might even be possible to including having the complicated permission of limitation (such as validity period).
Further, the present embodiment does not limit by way of sending finance change transaction into block chain, such as can
To be to send finance change transaction by external call interface, or send finance change transaction by intelligent contract-defined interface.
Specifically, user can operate financial payments information by calling the external interface.Either user is by calling intelligent contract
Interface makes intelligent contract during execution, operates financial payments information by intelligent contract virtual machine.By intelligent contract
Interface is, it can be achieved that carry out the automatic configuration of financial payments using intelligent contract.Certainly it as being not necessarily to automatic configuration, can not also mention
For the intelligent contract-defined interface with the function.Other intelligent contracts on block chain, can be by the message call between contract, directly
Change obtains financial payments information.The access interface of external user can be JSONRPC.It is said by taking JSONRPC interface as an example below
The concrete form of bright finance change transaction request.
JSONRPC interface requests example:
{"jsonrpc":"2.0","method":"get_permission","params":["0x123456789012
3456789012345678901234567890"],"id":1}
JSONRPC interface responds example:
{"jsonrpc":"2.0","id":1,"result":{"change_permission":false,"deploy_
contract":true,"send_transaction":false}}
Since finance change transaction is similar with other general transactions, it is therefore desirable to so that block chain can recognize that the power
Limit change transaction.The present embodiment does not limit specific recognition methods.Such as it can be special by being added in finance change transaction
Different mark is allowed to distinguish with general transaction, is also possible to by sending the corresponding special interface of finance change transaction
The unique identification informations such as address are allowed to distinguish with general transaction.The present embodiment does not limit the type and form of mark, only
If can have unique corresponding relation with finance change transaction.I.e. optional, the finance change that identification user sends is handed over
Easily may include；Receive the transaction that user sends；Judge whether transaction has finance change transaction setting mark；If having,
Determine transaction for finance change transaction.
Specifically, the present embodiment does not limit the form of finance change transaction setting mark.Such as it can be in transaction
Add special identifier position；Either according to the address etc. of the intelligent contract of calling.For example, user can directly transmit transaction, call
Interface in financial payments intelligence contract.Can distinguish whether the transaction is finance change transaction according to the address for calling contract.Or
User sends finance change transaction and arrives block chain, which has special mark, so that block chain can recognize that the transaction
Operation is finance change.
The present embodiment is not defined content and content format etc. for including in finance change transaction, and user can be with
It is set according to the actual situation.But finance change transaction at least needs to include the promoter of finance change transaction, change
Permission user (external account address can be used to indicate in user i.e. to be changed) need to change financial (permission i.e. to be changed
Project, such as deployment contract, send transaction etc.), change the finance value (value of permission i.e. to be changed, such as True can be used
Or False is indicated).
S110, judge whether the promoter in finance change transaction has finance change finance.
Specifically, step S110 and S120 are specific implementation procedure of trading to finance change.Wherein step S110 is main
It is to judge whether finance change transaction initiator is legal, i.e., whether promoter has permission the change modification behaviour for executing block chain finance
Make.Only when finance change transaction initiator is legal, specific change operation can be just executed.When finance change transaction initiator
When illegal, then finance change Fail Transaction.The present embodiment does not limit specific deterministic process, and the process and financial payments are believed
The preservation form of breath etc. is related.How permission is saved, such as how tieed up in such a application scenarios of block chain
Hold an authority list.It, can be to the change record of financial payments information in order to further ensure the reliability of financial payments management
It is protected, can not be tampered by cryptography means.It is also convenient for audit.Such as a kind of number that can verify that using cryptography
Financial payments information is saved according to structure.The data structure is saving except initial data, provides check information.Check information
It has the property that
First: identical initial data check information having the same.
Second: being difficult to construct matching initial data according to check information.
Wherein, information field is generated usually using the digest algorithm in cryptography.The check information of financial payments information
As critical field, it is included in block structure.The meaning of critical field is: the field can be encoded into block data, and
For generating the Hash of block.By above-mentioned design, the variation of financial payments information will lead to the variation of its check information, verification
The variation of information will lead to the variation of block data and its Hash.Therefore, it can quickly check that financial payments are believed by block Hash
Whether breath is correct, and financial payments information is made to be difficult to be tampered.Any block Hash that can result in can be used that determining sexually revise occurs
Method realized to realize, such as by Trie.Preferably, the mode that permission saves in block chain may include: to utilize number
Each financial payments information is handled according to digest algorithm, generates the corresponding check information of each financial payments information；In area
The critical field for increasing the check information in block structure, for recording the corresponding financial payments information of each block.It is every in this way
The variation of corresponding check information in a block (i.e. the block correspond to critical field data) will lead to the block data and its
The variation of Hash.Therefore, can quickly check whether financial payments information is correct by block Hash, be difficult to financial payments information
Changed.A kind of optional embodiment is set forth below.
Judge the promoter in finance change transaction whether there are finance change finance to may include: to obtain from block chain
Newest block, and root of the check information as MPT tree is obtained from newest block；Using the root construction MPT tree of MPT tree, and from
The corresponding financial payments information of promoter is obtained in MPT tree；The initiation in finance change transaction is judged according to financial payments information
Whether person has finance change finance.Wherein, the preservation form of the corresponding financial payments information of this kind of judgment mode can be such that
It is set using MPT (Merkle Patricia Trie) and saves permissions data, and use the Hash of its root node as permissions data
Check information.Block field (such as permissions field) is increased newly in block structure, for saving the school of permissions data
Test information.The structure of permissions data can be the list based on user, list based on group etc., herein with no restrictions.It is related to
Permission can be configured according to the characteristic of block chain, such as send transaction, deployment contract, call read-only interface, specifically not
It is limited.At this time according to the characteristic of block chain, the financial payments information in a certain block can be obtained, the specific steps are as follows:
