Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of flow diagram of the verification method for block chain data that the embodiment of the present invention one provides, this implementation Example is applicable to electronic equipment and obtains data from block chain network node, and to the feelings that the block chain data of acquisition are verified Condition, this method can be executed by the verifying device of block chain data, and the device is by software and or hardware realization and concrete configuration In electronic equipment, which can be regular node or lightweight node in block chain network, be also possible to non-area Block chain network node.
The embodiment of the present invention is applicable to the Transaction Information verifying of processing diversified forms, especially suitable in Transaction Information Appearance cannot solely carry out the case where hash signature forms Transaction Identifier.Bit coin (UTXO) illustrated below combines ether mill (EVM) the Transaction Information form of intelligent forms of contract.
According to the needs of affairs, there are the transactions requests of readable field form in conjunction with the transactions requests of code segment form Form.For example, being embedded in the intelligent contract code of EVM in the certain field of UTXO.When handling the transactions requests, on the one hand want Processing field content forms Transaction Information, on the other hand also to run intelligent contract, generates the operation result of intelligent contract.Fortune Row result is generally stored in block with Transaction Information, but is not stored at together.It and is usually first to generate Transaction Information It is added in block, Hash calculation is carried out to the Transaction Information and generates Transaction Identifier, then run intelligent contract, operation result Continue storage within a block.Therefore the content of operation result can not be embodied in Transaction Identifier, so difficult in the prior art With verifying.
The embodiment of the present invention is various informative for this Transaction Information, cannot unify the feelings verified by single Transaction Identifier Condition provides solution.The verification method of the block chain data specifically includes:
S110, Transaction Information acquisition request is initiated to block chain network node, and receives the Transaction Information of feedback.
Block chain is a kind of a kind of chain type number for being sequentially in time combined into data block in such a way that sequence is connected According to structure, and the distributed memory system that can not be distorted He can not forge guaranteed in a manner of cryptography.And it is stored in block Its generating process of Transaction Information it is to be understood that when have transactions requests be sent to block generate node when, block generate node Transactions requests can be handled and generate Transaction Information storage into block.
Wherein, block chain network node can be understood as participating in the generation for each block that block chain is included, storage and/ Or the hardware carrier for having certain data-handling capacity of the processes such as verifying.Illustratively block chain network node can be clothes The electronic equipments such as business device, mobile terminal or server cluster.
For the electronic equipment in block chain network or outside network, or it is carried on the client of electronic equipment, it is possible to meeting Need to obtain the Transaction Information stored in block chain network node.At this point it is possible to any one or more block chain network sections Point initiates Transaction Information acquisition request, to receive the Transaction Information of feedback.
Illustratively, initiating Transaction Information acquisition request to block chain network node may is that the trusted node to itself Transaction Information acquisition request is initiated, to improve the confidence level of acquired Transaction Information.Wherein, trusted node can be credit compared with High node is also possible to the node that the electronic equipment often contacts.
Illustratively, it may also is that block chain network node initiation Transaction Information acquisition request wide to block chain network Transaction Information acquisition request is broadcast, after the node for having storage capacity receives the Transaction Information acquisition request, feedback is corresponding Transaction Information.Certainly, in order to improve the acquisition efficiency of Transaction Information, Internet resources are saved, electronic equipment can also be only to choosing The node for having storage capacity of the setting quantity taken initiates Transaction Information acquisition request.
It is S120, corresponding block-identified according to the Transaction Information, Transaction Identifier array is initiated to block chain network node Acquisition request, and obtain the Transaction Identifier array in block.
It should be noted that the data structure of block includes block head and block body.Wherein, block generates node and is based on respectively Transactions requests Transaction Information generated is stored in block body；The basis being calculated based on Transaction Information by hash signature Transaction Identifier is stored in the Transaction Identifier array of block head；What the hash signature two-by-two based on each underlying transaction mark was constituted Block-identified also correspondence determined by the root of Mei Keer tree is stored in block head.
Can be determined according to the Transaction Identifier for the Transaction Information to be obtained it is corresponding block-identified, and then be based on block mark Know and requires to obtain Transaction Identifier array.Alternatively, Transaction Identifier can also be provided directly, corresponded to be inquired in block chain network It is block-identified.
When obtaining Transaction Identifier array, block chain network node can directly feed back array, can also be by block head or whole A block feeds back offer, and then electronic device voluntarily extracts Transaction Identifier array again.
That is, it is corresponding block-identified according to the Transaction Information, block acquisition request is initiated to block chain network node, and Receive the block of feedback；Transaction Identifier array is extracted from the block.
S130, underlying transaction mark and appended transaction mark are extracted from the Transaction Identifier array.
Wherein, Transaction Identifier of the Transaction Identifier array to store unique characterization Transaction Information.Wherein, Transaction Identifier can be with It can also include to characterize the additional of the operation result of intelligent contract including the underlying transaction mark to characterize Transaction Information Transaction Identifier.
It should be noted that the Transaction Information stored in same block can be at least one, therefore corresponding basic thing Business mark is at least one；It is at least that embedded intelligent contract, which is at least one or operation result, in same Transaction Information One, therefore corresponding appended transaction mark is also at least one.
In general, the mark address for the Transaction Information that can be inquired, refers to that underlying transaction identifies, therefore, can pass through pass Join storage location or establish the mode of index, embody the incidence relation of underlying transaction mark and appended transaction mark, thus convenient It can extract together.
S140, the Transaction Information is verified according to underlying transaction mark and appended transaction mark.
On the one hand pass through processing field content formation Transaction Information when handling transactions requests since block generates node, separately On the one hand operation result is generated by running intelligent contract.And Transaction Information and operation result are stored in the different memory areas of block Domain.Therefore, it is necessary to be verified respectively to Transaction Information corresponding with field contents and intelligent contract operation result, just realize To the integrity authentication of Transaction Information in block.
Wherein, the underlying transaction mark if inquired may is that the verification mode of the corresponding Transaction Information of field contents Knowledge is identical as the underlying transaction mark that Transaction Information acquisition request is included, or the underlying transaction mark inquired is set with electronics The standby underlying transaction mark being locally stored is identical, it is determined that Transaction Information acquired in electronic equipment is correct.
Wherein, it may also is that the Transaction Information to feedback to the verification mode of the corresponding Transaction Information of field contents Hash calculation is carried out with the corresponding Transaction Identifier of determination, verifying is compared with underlying transaction mark in the Transaction Identifier of calculating, With the correctness of the determination Transaction Information.Specifically, if the Transaction Identifier and consistent, the table of underlying transaction mark that calculate Transaction Information acquired in bright electronic equipment is correct.
Wherein, being subject to verification mode to intelligent contract operation result may is that if it is determined that there are the appended transaction marks Know, it is determined where the corresponding intelligent contract operation result of the Transaction Information is present in the Transaction Information in block.At this point, It can determine that intelligent contract was performed in block chain network, and the successful storage table wisdom energy contract of appended transaction mark The correctness of operation result obtained the verifying of each network node in block chain network, so electronic equipment can directly determine The operation result of each intelligence contract is correct.
Wherein, it is subject to verification mode to intelligent contract operation result and may also is that rerun each intelligent contract and obtain Corresponding operation result；Hash calculation is carried out to operation result and determines corresponding cryptographic Hash；By the cryptographic Hash of calculating and additional thing Verifying is compared in business mark, to determine the correctness of intelligent contract operation result.Specifically, if identified cryptographic Hash with The appended transaction mark of extraction is consistent, then shows that each intelligence contract was performed in the Transaction Information and operation result is correct.
Electronic equipment can be according to the verifying degree to block, according to electronic equipment own hardware condition and block chain network Degree of participation, to determine specifically using which kind of verification mode.Preferably, the executing subject of the embodiment of the present invention is block chain network Lightweight node.Wherein, block chain network lightweight node is not stored or storage section block data and Transaction Information.Wherein, The Partial Block Data that block chain network lightweight node is stored may include the Transaction Identifier etc. in block head.
It should be noted that the embodiment of the present invention only in the form of the transactions requests of UTXO combination EVM intelligence forms of contract into Row exemplary illustration, when Transaction Information generated includes two parts and memory block to transactions requests after block generates node processing When the difference of domain, Transaction Information can be verified using the verification method of the embodiment of the present invention.Illustratively, when affairs are asked When the intelligent forms of contract of Seeking Truth EVM code segment form, due to the corresponding Transaction Information of intelligent contract itself and intelligent contract Operation result storage region it is also different, therefore equally can using the embodiment of the present invention verification method to Transaction Information carry out Verifying.
Preferably, Transaction Information corresponds to the digital cash transaction bill of readable field form, wraps in the Transaction Information Include the intelligent contract of code segment form.
The embodiment of the present invention is by initiating Transaction Information acquisition request to block chain network node and receiving the affairs of feedback Data；According to it is corresponding with Transaction Information it is block-identified to block chain network node send Transaction Identifier array acquisition request, and Obtain the Transaction Identifier array in block；Underlying transaction mark and appended transaction mark are extracted from Transaction Identifier array；According to The underlying transaction mark and appended transaction mark of extraction verify Transaction Information.By adopting the above technical scheme in verifying affairs When data, it is contemplated that various forms of Transaction Informations introduce appended transaction mark, store in block chain so as to verify Multiple portions Transaction Information content, be suitble to different form Transaction Information the case where being verified.
Embodiment two
Fig. 2 is a kind of flow diagram of the verification method of block chain data provided by the embodiment of the present invention two.This hair Bright embodiment has carried out additional optimization on the basis of the technical solution of the various embodiments described above.Further, in operation " according to institute State underlying transaction mark and appended transaction mark verify the Transaction Information " after, it is additional " according to the Transaction Information It is corresponding block-identified, block acquisition request is initiated to block chain network node；According to locally obtain current block mark and It is previous block-identified, and feedback block current block mark and it is previous block-identified, the block is verified ", with Whether block where verifying Transaction Information is effective.
The verification method of block chain data as shown in Figure 2, specifically includes:
S210, Transaction Information acquisition request is initiated to block chain network node, and receives the Transaction Information of feedback.
Electronic equipment directly acquires the underlying transaction mark being locally stored, or directly acquires basic thing from affairs initiator Business mark, or underlying transaction mark is obtained from other block chain network nodes；It identifies to form Transaction Information based on underlying transaction Acquisition request simultaneously sends the Transaction Information acquisition request to block chain network node；When block chain network node receives number of transactions After acquisition request, Transaction Information corresponding with underlying transaction mark is fed back to electronic equipment.
It is S220, corresponding block-identified according to the Transaction Information, Transaction Identifier array is initiated to block chain network node Acquisition request, and obtain the Transaction Identifier array in block.
S230, underlying transaction mark and appended transaction mark are extracted from the Transaction Identifier array.
S240, the Transaction Information is verified according to underlying transaction mark and appended transaction mark.
It is S250, corresponding block-identified according to the Transaction Information, block acquisition request is initiated to block chain network node.
Electronic equipment can be corresponding block-identified to other block chain network nodes according to the Transaction Information got Initiate block acquisition request, after corresponding block chain network node receives block acquisition request, to electronic equipment feedback with Block-identified corresponding block.
This step can execute together with S220, i.e., block acquisition request is equivalent to Transaction Identifier array acquisition request, Transaction Identifier array can be extracted from the block of acquisition.
S260, according to locally obtain current block mark and it is previous block-identified, and feedback block current block It identifies and previous block-identified, the block is verified.
The embodiment of the present invention can be determined the verification method of block by mathematical induction:
1) the block-identified blockid [0] for creating generation block block [0] generally acknowledges effectively, therefore defaults each in block chain network The block data of the wound generation block of network node is effective.
2) the after being connected to wound [0] generation block block from block chain acquired in other block chain network nodes The previous block-identified blockid [0] that one block block [1] is stored is locally stored previous block-identified with electronic equipment Blockid [0] is identical, and the first block block [1] acquired in other block chain nodes meets common recognition algorithm and the firstth area The digital signature of block block [1] is equal to current block mark blockid [1] that electronic equipment is locally stored, then showing electronics First block block [1] of other block chain network nodes that equipment obtains is effective.
3) assume that the either block block [i] in block chain acquired in electronic equipment is correct and effective, then electronics is set The previous block-identified blockid [i] that the standby latter block block [i+1] obtained from other block chain network nodes is stored It is identical as previous block-identified blockid [i] that electronic equipment is locally stored, and acquired in other block chain network nodes Latter block block [i+1] meets common recognition algorithm and the digital signature of latter block block [i+1] is equal to electronic equipment local The current block of storage identifies blockid [i+1], then showing the latter of other block chain network nodes that electronic equipment obtains Block block [i+1] is effective.
It can be concluded based on above content and show that the whether effective step of verifying block may is that area of the electronic equipment from acquisition In block obtain current block mark be locally stored current block mark compared to pair, acquisition the first comparison result；Electronic equipment Obtained from the block of acquisition it is previous it is block-identified be locally stored it is previous it is block-identified compared with pair, obtain second compare knot Fruit；When the first comparison result is identical and the second comparison result is identical, show that acquired block is effective.
It should be noted that needing to follow certain common recognition algorithm, generation is set when block chain network node generates block Fixed data are as in block, so which the generation node for showing block is.Therefore, it in verifying, not only needs by working as The correctness of preceding block-identified verifying block data, it is also necessary to whether be based on data verification block data added by common recognition algorithm It is generated by correct node.
The technical solution of the embodiment of the present invention passes through additional block verification step, block where further verifying Transaction Information Data validity, the block for preventing the Transaction Information by acquisition from being stored has been rolled back, namely the received number of transactions of institute According to not actual stored in block chain, the confidence level of Transaction Information verification result is improved.
Embodiment three
Fig. 3 is a kind of flow diagram of the verification method of block chain data provided by the embodiment of the present invention three.This hair Bright embodiment has carried out subdivision optimization on the basis of the technical solution of the various embodiments described above.The present embodiment is light with electronic equipment It is illustrated for magnitude node
Further, operation " is extracted underlying transaction mark from the Transaction Identifier array and appended transaction identifies ", Be refined as " it is identified based on the underlying transaction locally obtained and searches corresponding underlying transaction mark in the Transaction Identifier array, And it extracts；The appended transaction mark that relative position is in underlying transaction mark is extracted from the Transaction Identifier array Know ", to improve the extracting mode of underlying transaction mark and appended transaction mark.
The verification method of block chain data as shown in Figure 3, specifically includes:
S310, Transaction Information acquisition request is initiated to block chain network node, and receives the Transaction Information of feedback.
Lightweight node directly acquires the underlying transaction mark being locally stored, and generates affairs based on underlying transaction mark Data acquisition request；Lightweight node sends the Transaction Information acquisition request to block chain network node；When block chain network section After point receives Transaction Information acquisition request, to lightweight node feeding back Transaction Information corresponding with underlying transaction mark.
Preferably, block chain network node is the believable one or more block chain network nodes of lightweight node.
It is S320, corresponding block-identified according to the Transaction Information, Transaction Identifier array is initiated to block chain network node Acquisition request, and obtain the Transaction Identifier array in block.
Lightweight node can also be directly obtained area corresponding with the Transaction Identifier while getting Transaction Identifier Block identification or lightweight node get corresponding with Transaction Information block-identified according to the Transaction Information of feedback；Light weight Grade node is based on block-identified formation block acquisition request, and sends the block acquisition request to block chain network node；Work as area After block chain network node receives the block acquisition request, to lightweight node feeding back and block-identified corresponding block；Gently Magnitude node receives the block and extracts Transaction Identifier array from the block head of block.
It should be noted that block chain network involved in the block chain network node involved in S320 and S310 Node can be the same or different.
S331, it is identified based on the underlying transaction locally obtained and searches corresponding underlying transaction in the Transaction Identifier array Mark, and extract.
Since lightweight node is when obtaining Transaction Information to other block chain network nodes, need using underlying transaction mark Know as acquisition foundation, therefore for the ease of the lookup of Transaction Information acquisition, each underlying transaction mark being stored in block head It can be stored in Transaction Identifier array according to the storage order of Transaction Information each in block correspondence.Correspondingly, lightweight node base It is identified in the underlying transaction locally obtained and searches same underlying transaction mark in Transaction Identifier array, and mentioned It takes.
S332, the appended transaction that relative position is in underlying transaction mark is extracted from the Transaction Identifier array Mark.
It is understood that for the ease of distinguishing the operation result of intelligent contract in each Transaction Information, each Transaction Information Appended transaction mark also will identify associated storage with underlying transaction.
Illustratively, it is extracted from the Transaction Identifier array with underlying transaction mark in the additional of relative position Transaction Identifier may is that the letter undetermined for extracting from the Transaction Identifier array and being in relative position with underlying transaction mark Breath；Determine the information undetermined for appended transaction mark based on the presetting bit content of the information undetermined.
Since underlying transaction mark and appended transaction mark are to be compressed data into using hash algorithm by number and word The hash character string that mother is combined into, therefore in order to be distinguish to underlying transaction mark and appended transaction mark, block generates section Point sets corresponding presetting bit when would generally appended transaction be identified and be stored when storing appended transaction mark.Wherein, presetting bit It can be some byte or some special bit.
Illustratively, it is extracted from the Transaction Identifier array with underlying transaction mark in the additional of relative position Transaction Identifier may also is that be extracted from the Transaction Identifier array, the continuous position of memory space with underlying transaction mark The appended transaction mark set；Or extracted from the Transaction Identifier array, exist with the storage location of underlying transaction mark The appended transaction of index relative identifies.Wherein, when there are the appended transaction of index relative marks to be stored in underlying transaction mark When appended transaction identifies array, a preset identifications can be only set, be attached to characterize the Transaction Identifier that the array is stored Add Transaction Identifier.
Preferably by the way of underlying transaction mark and appended transaction mark Coutinuous store.In this way in Transaction Identifier array In find underlying transaction mark when, subsequent appended transaction can be obtained immediately and identified, search efficiency is improved, also reduce Required index data.
S340, the Transaction Information is verified according to underlying transaction mark and appended transaction mark.
The extraction operation that the embodiment of the present invention is identified by refinement underlying transaction mark and appended transaction is further perfect The verification method of block chain data.By adopting the above technical scheme, it can verify when verifying Transaction Information and be stored in block chain Multiple portions Transaction Information content, be suitble to different form Transaction Information the case where being verified.
