Embodiment two

Fig. 2 is a kind of flow chart of the verification method of block chain provided by Embodiment 2 of the present invention, and the present embodiment is with above-mentioned It is embodied based on embodiment, in the present embodiment, gives block verifying node according to thing in the block to be verified The data source identification information for data of being engaged in, to the Transaction Information progress data verification in the block to be verified, and according to The more new information of data identification information carries out the specific implementation of data update.Correspondingly, as shown in Fig. 2, the present embodiment Method may include：

S210, block verifying node receive block and generate the block to be verified that node is sent, and the block generates node and is The node elected by setting common recognition mechanism.

S220, block verifying node are right according to the data source identification information of Transaction Information in the block to be verified The Transaction Information in the block to be verified carries out data verification.

Correspondingly, S220 can specifically include following steps：

S221, block verifying node are if it is determined that there is no data source identifications to believe in currently processed Transaction Information The currently processed Transaction Information is then sent to certification node and authenticated by breath.

Wherein, certification node can be in block chain network for authenticating to the authenticity and validity of transactions requests Node.Authenticating node can be in the side chain of block chain network, subchain or lightning network to the related data in transactions requests Source-information authenticated.Authenticating node can be odd number, and verify node return authentication result to block.It needs to illustrate , representative and authoritative node can be selected as certification node in block chain network, and authenticate node It is not involved in the verification process of block to be verified, is merely responsible for authenticating the related data of transactions requests.

In embodiments of the present invention, if block verifies node when verifying to currently processed Transaction Information, hair Now corresponding data source identification information is not present in the Transaction Information, then needs for currently processed Transaction Information to be sent to certification section Point is authenticated.Optionally, node can be generated by block send the currently processed affairs for needing to authenticate to certification node Data.

The authentication result that S222, block verifying node return to the certification node, as to described currently processed Transaction Information authentication result.

Correspondingly, certification node is to side chain of the currently processed Transaction Information to be certified in block chain network, subchain Or lightning network carries out the certification of data validity.The authentication result of certification node may include authenticating to pass through and authenticate not passing through Two kinds of situations.After block verifying node receives the authentication result of certification node feeding back, according to authentication result to currently processed Transaction Information is verified.

S223, block verifying node if it is determined that there are data source identification information in currently processed Transaction Information, Data source identification information is then extracted in the data content of currently processed Transaction Information.

Wherein, data source identification information can be processed affairs included in currently processed Transaction Information The corresponding data identification information of data, i.e. historical data identification information.

S224, block verifying node according to the data source identification information of extraction, obtain with it is described currently processed The associated historical transactions data of Transaction Information as verify data, and according to the verify data, to described currently processed Transaction Information is verified.

If finding the number of transactions correspondingly, block verifies node when verifying to currently processed Transaction Information According to there are corresponding data source identification information, then authenticated it is not necessary that currently processed Transaction Information is sent to certification node, Can data source identification information to be extracted in the data content of the currently processed Transaction Information of direct basis, in the local database Corresponding historical transactions data are searched as verify data, to realize the verifying to currently processed Transaction Information.

S230, block verifying node are according to the data verification to Transaction Information in the block to be verified as a result, obtaining To the block verification result to the block to be verified, and the block verification result is fed back into the block and generates node, So that the block generates node and determines whether the block to be verified passes through common recognition.

Wherein, block verification result can be block to be verified be verified or block to be verified verifying do not pass through.

Correspondingly, after each block verifying node completes verifying to every Transaction Information in block to be verified, formation pair The block verification result answered.The block verification result that block verifying node can be obtained is passed in block chain network It is defeated, node is generated to be sent to block.

S240, block verifying node receive the common recognition of the block generation node feeding back by response, or simultaneously Receive the update result for the data identification information of target transaction data in the block to be verified；The data identification information More new information by certification node generate.

Wherein, common recognition can be block by response and generate node block to be verified according to determined by block verification result Common recognition result.Such as in the common recognition algorithm based on Raft, set when the ratio being verified in block verification result is more than or equal to When determining threshold value, such as (f+1)/(2f+1), then block, which generates node and can be generated, shows that block to be verified is logical by the common recognition of common recognition Cross response.

In embodiments of the present invention, when the common recognition that block verifying node receives block generation node feeding back passes through response Afterwards, it is determined that block to be verified passes through common recognition.Meanwhile block verifying node can also receive block and generate the to be tested of node transmission Demonstrate,prove the update result of the data identification information of target transaction data in block.

S250, if receive it is described update as a result, if block verifying node according to the data identification information more New information is updated the Transaction Information in the block to be verified, while to the historical transactions data being locally stored It is updated, and the block to be verified is added in block chain.

Correspondingly, block verifying node gets the data identification information for authenticating node for target transaction data feedback After more new information, the Transaction Information that can be treated according to the more new information of data identification information in verifying block is updated, and Updated block to be verified is added to the tail portion of block chain, to complete uplink operation.

It should be noted that block verifies node in addition to that can treat verifying area according to the more new information of data identification information The Transaction Information of block is updated, can also according to data identification information more new information to the historical transactions data being locally stored It is updated.After the completion of update, block verifying node not will be deleted the historical transactions data being locally stored.The history being locally stored Transaction Information can be used for the processing of subsequent transaction request.

In an alternate embodiment of the present invention where, the Transaction Information includes：Data of financial transaction, the data source mark Knowing information includes：The number of historical financial transaction data, i.e. historical data identification information；The block verifying node is according to extraction The data source identification information, obtain with the associated historical transactions data of the currently processed Transaction Information as verifying number According to, and according to the verify data, the currently processed Transaction Information is verified, including：The block verifies node According to the number of the historical financial transaction data, historical financial corresponding with the number of the historical financial transaction data is obtained Transaction data, the block verifying node obtain the whole for being transferred to account corresponding with the historical financial transaction data and are transferred to volume Degree produces the total value of account as currently processed data of financial transaction；It is currently processed described in the block verifying node verification At least one in data of financial transaction produce account the summation for producing amount whether with the currently processed financial transaction number Match according to the total value for producing account；If so, the block verifying node determines the currently processed data of financial transaction Pass through verifying.

Wherein, financial transaction includes but is not limited to funds transaction and share exchange etc..The number of data of financial transaction can be with It is the number of arbitrary data structure type, is specifically as follows the character string including node identification, such as A0001, it is of course also possible to Random number is added in number, avoids generating repetition number, such as number can be Ar0001, wherein r is random number, the random number It is generated by certification node, the digit of random number can be set according to actual needs, and the random number generated every time is different from, and should Ar in number is only as mark, without counting, is counted by 0001 in number as starting number, such as work as r=123 When, the count range of initial number A1230001 is A1230001-A1239999.The embodiment of the present invention is not handed over realization finance The method and form of the number of easy data are defined.

In embodiments of the present invention, optionally, it can be handled financial transaction as transactions requests.Specifically, area Block verifies node and obtains associated historical transactions data to currently processed Transaction Information progress according to historical data identification information It, can be using the number of historical financial transaction data as historical data identification information, and by historical financial transaction data when verifying The corresponding historical financial transaction data of number as associated historical transactions data.Block verifies node and trades to current financial When data are verified, the corresponding whole for being transferred to account of associated historical financial transaction data can be transferred to amount as working as The data of financial transaction of pre-treatment produces the total value of account, and verifies at least one in currently processed data of financial transaction and produce The total value whether summation for producing amount of account produces account with currently processed data of financial transaction matches, and matches then table Bright currently processed data of financial transaction passes through verifying；Otherwise, show that currently processed data of financial transaction is unverified.

In a specific example, block generates node can store complete finance in the local data base of oneself Transaction record, remaining node are that ordinary node namely block verify node, and block verifies node can be in oneself local data Newest financial transaction record is stored in library.Stored financial transaction record can be used as input transaction note in database It records, financial transaction record to be verified can be used as output transaction record in block.In addition to financial transaction source data, every output Transaction record all must be able to find corresponding input transaction record in the local database, the turnover of every output transaction record Spending total value must be consistent with the transaction limit total value of corresponding input transaction record.

The financial transaction record of oneself is sent in public transaction buffer area by each node, and block generates node from public affairs A plurality of financial transaction record is taken out in total transaction buffer area and is put into block to be verified, and a plurality of financial transaction record is carried out The result of Hash operation is utilized oneself private key encryption by Hash operation, and encrypted Hash result is put into together to be tested It demonstrate,proves in block, then broadcasts the block to be verified on block chain.Block generates node and participates in verifying, and block verifying node connects After receiving the block to be verified, the cryptographic Hash in the public key decryptions block to be verified of node is generated using block as a result, obtaining Hash result after decryption, then carries out Hash operation to a plurality of financial transaction record in block to be verified, and comparison operation obtains To Hash result and block in decrypt after Hash result, unanimously then think the block to be verified be by block generate node hair It is not tampered with out and in transmission process.The public key that block generates node can obtain from certification node.

Block verifying node successively detects whether every financial transaction record in block to be verified has corresponding transaction Source number.If not trading source number, this financial transaction record is sent to certification node.Node is authenticated to this Financial transaction record is authenticated, and verifies node return authentication as a result, block verifies node according to the authentication result to block It is verified.If there is transaction source number, then corresponding input is found in local database by transaction source number Transaction record, comparison input transaction record in transaction limit total value and output transaction record in transaction limit total value whether one It causes, is unanimously then verified.If all financial transaction records and output transaction record in block to be verified are verified, Block verifies node and generates the response that node return block is verified to block.Block generates node and receives a certain proportion of test After demonstrate,proving the response passed through, then determine that block common recognition to be verified passes through.Then block generate node check in block to be verified whether In the presence of the financial transaction record of not initial number, then corresponding financial transaction record is sent to certification node to apply if having Corresponding initial number, certification node, which assigns initial number to this financial transaction record and returns to block, generates node.Area The common recognition that block generates node and can pass through the financial transaction record for having initial number information and common recognition passes through response in block Broadcasted in chain, receive broadcast message block verifying node and block generate node by block to be verified without initially compiling Number financial transaction record be updated, then the block to be verified of update is added to the tail portion of block chain, to complete cochain Operation.Meanwhile each node in block chain network can also be according to the financial transaction record with initial number information to local The financial transaction record of database purchase is updated.

Specifically, can select some authoritative nodes as certification node, such as bank or transaction in block chain network Institute's node.Certification node is not involved in the verification process of block to be verified, is merely responsible for certification financial transaction record and provides number.Example As, there are node A-F, interior joint D-F is authenticates node, and node A-C is block chain node, and node A is that block is raw in block chain At node, node A-C has the local data base of oneself.Node B is by a financial transaction record { SN：, IN：1000000, quantity： 10000 T stocks, OUT：The address of node B } it is sent in public transaction buffer area, wherein SN indicates this financial transaction record Corresponding number, and the corresponding number of IN expression historical financial transaction record (when financial transaction record is initial transaction record, IN Can indicate the original asset information of current financial transaction record, i.e., data source identification information is not present in IN field at this time), number Amount can be particular transactions quantity involved in financial transaction, and OUT indicates transaction output object, and the address of node B is node B's Account, concretely random string.This financial transaction record has meant that a transaction is that node B spends 1,000,000 purchases 10,000 T stocks have been bought, have been placed in the address of node B.Block generates node A and takes out this gold from public transaction buffer area Melt transaction record, and Hash operation is carried out to this financial transaction record, the result of Hash operation is added using the private key of oneself It is close, and this financial transaction record and encrypted Hash result are put into together in block to be verified, it is then that this is to be verified Block is on block chain to all node broadcasts for participating in common recognition.After block verifying node B and C receive the block to be verified, The cryptographic Hash in the public key decryptions block to be verified of node A is generated using block as a result, Hash result after being decrypted, so Hash operation carried out to this financial transaction record in block to be verified afterwards, Hash result that comparison operation obtains and to be verified Hash result after decrypting in block unanimously then thinks that the block to be verified is to generate node by block to issue and be transmitted across It is not tampered in journey.

Further, node A-C detects this financial transaction record, detects in IN field and compiles without discovery transaction source Number, then this financial transaction record is financial transaction source data, this financial transaction record is then sent to certification node D- F.Optionally, node A can be generated by block send, certification node D-F receive after this financial transaction record side chain, The authenticity of rapid authentication this financial transaction record in subchain or lightning network.It can specifically be looked into according to the address of node B Corresponding Transaction Details are ask, generate the authentication result that node A return authentication passes through to block if query result matching.Block Generate authentication result of the node A to block verifying node B-C notice certification node.Block is verified after node B-C is checked to block It generates node and returns to the response being verified, the node A of block generation at this time judges area to be verified according to the verification result received Block passes through common recognition.Through common recognition, block is generated to whether there is in node A inspection block to be verified and not compiled initially Number financial transaction record, find this financial transaction record and by this financial transaction record to any certification node send Shen It please corresponding initial number.Certification node search to this financial transaction record that discovery is authenticated to be passed through, in being to confer to Initial number B0001 simultaneously returns to block generation node A, and block generates the financial transaction that node A will have initial number B0001 It is recorded in block chain network and is broadcasted.Node A-C will be to be verified according to the financial transaction record with initial number B0001 Financial transaction record in block is updated, i.e., by initial number B0001 assign SN field, then by block to be verified more Whole financial transaction records after new are added block chain and are stored in the local data base of oneself, realize to local data base more Newly.That is, all storing financial transaction record { SN in the local data base of node A-C at this time：B0001, IN：1000000, quantity：1 Ten thousand T stocks, OUT：The address of node B }.

Correspondingly, node B is counted automatically to SN and life when the SN of the blending transaction data stored in database is not sky The number of Cheng Xin, then by next financial transaction record { SN of generation：C0001, IN：B0001, quantity：2000 T stocks, OUT：The address of node C；SN：B0002, IN：B0001, quantity：8000 T stocks, OUT：The address of node B } be sent to it is public In transaction buffer area.This financial transaction record means that the first transaction is that 2,000 T stocks are given to node C by node B, puts In the address of node C, the second transaction is that remaining 8,000 T stock is given to oneself by node B, is placed in the address of node B. Block generate node A from taken out in public transaction buffer area be put into block after this financial transaction record is handled it is wide It broadcasts, node A-C, which is detected in the IN field of this financial transaction record, has transaction source number, then from local data base It finds the financial transaction record that number is B0001 and inputs transaction record.Node A-C is calculated in input transaction record, that is, B0001 Transaction limit total value be 10,000 T stocks, and calculate input transaction record B0001 it is corresponding all output transaction record i.e. C0001 It is 2,000 plus 8,000 T stocks i.e. 10,000 T stocks with the transaction limit total value in B0002, compares two calculated result discovery input transaction Transaction limit total value in record is consistent with the transaction limit total value in output transaction record, then generates node A to block and returns Return the response being verified.Block generates node A and receives to be verified response and then thinks that common recognition is logical more than or equal to a certain proportion of It crosses, such as receive 2f+1 node in the 3f+1 node based on PBFT algorithm be verified response, based on Raft algorithm F+1 node is received in 2f+1 node is verified response.Common recognition generates node by rear block will be by the area of common recognition Block chain is added in block, and passes through response to other blocks verifying node broadcasts common recognition (block content does not have to update at this time).Block Block chain will be added by the block of common recognition by response according to common recognition by verifying node, and respectively be carried out more to local data base Newly, corresponding financial transaction record is stored.It should be noted that block, which generates node, can store whole financial transaction notes Record, and block verifying node then can only store newest transaction record.Stored in the database of the node A of block generation at this time Financial transaction record be { SN：B0001, IN：1000000, quantity：10000 T stocks, OUT：The address of node B；SN：C0001, IN： B0001, quantity：2000 T stocks, OUT：The address of node C；SN：B0002, IN：B0001, quantity：8000 T stocks, OUT：Node B Address, the financial transaction record that stores is { SN in the database of node B and C of knowing together：C0001, IN：B0001, quantity：2000 T stock, OUT：The address of node C；SN：B0002, IN：B0001, quantity：8000 T stocks, OUT：The address of node B }.This time The financial transaction record with number that point C has had node B to be assigned according to data of financial transaction.
