It extracts, and other remaining nodes is formed into subclass, in order to be verified subsequently through each node with subclass,
The problem of avoiding authentication error caused by a large amount of accounting nodes carry out non-ordered data validation-cross, so as to improve each book keeping operation
The accuracy verified between node, and then improve the accuracy of block chain book keeping operation.
204th, when receiving transaction request, each accounting nodes are verified according to the first random number.
Wherein, first random number each accounting nodes generate and send at random, the transaction request
Concept explanation can be referred to and accordingly be described in the step 102, and details are not described herein.
This step specifically includes：Corresponding first random number of each accounting nodes and cryptographic Hash are obtained, it is described
Cryptographic Hash each accounting nodes carry out Hash operation according to first random number and obtain；The Hash is sent respectively
It is worth to remaining described accounting nodes in the accounting nodes subclass；First random number is sent respectively to the book keeping operation section
Remaining described accounting nodes in point subclass, so that each accounting nodes are according to the random number and the cryptographic Hash
It is mutually authenticated.
That is in this step, a random number r is generated respectively for each accounting nodes P, and random to this
Data carry out the cryptographic Hash hash (r) that Hash operation obtains, and then first send hash (r), in order to be saved with book keeping operation
Remaining node in the corresponding subclass of point P all receives and preserves the cryptographic Hash, then again sends random number, from
And the random data that remaining each node receives after in subclass carries out Hash operation and the Hash with receiving before
Value is compared, and realizes being mutually authenticated between each accounting nodes.
For example, preserving 3 accounting nodes in the corresponding accounting nodes set of certain block catenary system, respectively book keeping operation saves
Point A, accounting nodes B and accounting nodes C then generate three subclass, and each subclass is configured with and each accounting nodes pair
The identifier answered, that is to say, that obtained subset corresponding with accounting nodes A is combined into：A { accounting nodes B, accounting nodes C }, with
The corresponding subsets of accounting nodes B are combined into：B { accounting nodes A, accounting nodes C }, subset corresponding with accounting nodes C is combined into：C { notes
Account node A, accounting nodes B }.When receiving task requests, by taking accounting nodes A as an example, random number r is firstly generateda, to this
Random number carries out Hash operation and obtains cryptographic Hash hash (ra) and sent, after server receives the cryptographic Hash,
The value is sent to the node in subclass A { accounting nodes B, accounting nodes C } corresponding with accounting nodes A, that is, into Kazakhstan
Uncommon value hash (ra) accounting nodes B and accounting nodes C are sent respectively to, the two nodes are to cryptographic Hash hash (ra) preserved,
The random number r that then accounting nodes A is generated againaIt is sent, is similarly eventually sent to accounting nodes B and book keeping operation saves
Point C, the two nodes are in the random number r for receiving accounting nodes A transmissionsaAfterwards, its cryptographic Hash is calculated and with receiving
hash(ra) be compared, realize the verification to accounting nodes A.
For the embodiment of the present invention, cryptographic Hash and random number are sent successively by triggering each accounting nodes, so that respectively
It can be mutually authenticated between a accounting nodes, and be judged in accounting nodes set with the presence or absence of malice according to verification result

After being worth and being verified, its verification result is fed back, such as is kept accounts when other whole node verifications of completion and each
When the cryptographic Hash and random number that node is sent match, then send and be verified response message, and when one in verification process
Denier finds then to send out authentication failed response message immediately during the unmatched accounting nodes of any one cryptographic Hash and random number, but
Specific embodiment is without being limited thereto.
For the embodiment of the present invention, by sending response message after the completion of the verification of each accounting nodes, in order to server
Taken further measures according to the response message of whole nodes, and only the equal response verification of whole nodes by when, just really
Surely it is safe accounting nodes to be verified namely each accounting nodes, it is ensured that the safety of block catenary system operation, into
And improve the safety of block chain book keeping operation.
206a, current accounting nodes are extracted from the accounting nodes set.
Wherein, the current accounting nodes are used to the data of the transaction block chain is written.
Specifically, this step includes：Call Predistribution Algorithm corresponding first random according to each accounting nodes
Number the second random number of generation；According to the corresponding default random number range of second random number, the current accounting nodes are determined.
Wherein, the Predistribution Algorithm can be random number algorithm, but not limited to this.Specifically, this step can be preset it is each
The corresponding numberical range of accounting nodes is X as accounting nodes 1 correspond to preset range1~X2, then with each book keeping operation
The random number of node generation is seed, and the current random number A of random number algorithm generation is called to belong to preset range X1~X2When, it will
Accounting nodes 1 are determined as current accounting nodes.
207a, the triggering current accounting nodes perform book keeping operation operation.
Specifically, corresponding concept explanation and embodiment can be referred to and accordingly described in the step 104 in this step,
Details are not described herein.
If with the step 205a step 205b arranged side by side, receive the verification that any one of accounting nodes are sent and lose
When losing information, abnormal accounting nodes are obtained.
Wherein, the abnormal accounting nodes are the random number and the unmatched node of the cryptographic Hash.It specifically, can be with
It is set in each accounting nodes, when the cryptographic Hash for detecting remaining accounting nodes is mismatched with random data, output
Warning information exports the identification information for mismatching node simultaneously, in order to quick and precisely determine abnormal nodes, but not limited to this.
For the embodiment of the present invention, by being mutually authenticated between each accounting nodes, and authenticating in the presence of malice
Acquisition abnormal nodes are triggered during node immediately, avoid ought not monitor abnormal nodes and caused by still carrying out the book keeping operation of block chain
The problem of data write error misses ensures that the accuracy of block chain data write-in.
206b, the abnormal accounting nodes are deleted from the accounting nodes set.
It should be noted that when there is the cryptographic Hash sent for the first time and second of unmatched section of random number sent
During point, showing the node, there are malicious operations, should immediately reject the node from accounting nodes set, and re-start new one
