Described in embodiment do not represent all embodiments consistent with this specification one or more embodiment.Phase
Instead, they are only some aspects phases with the one or more embodiments of as detailed in the attached claim, this specification
The example of consistent device and method.
It should be understood that the sequence that might not show and describe according to this specification in other embodiments executes
The step of correlation method.In some other embodiments, step included by method can than described in this specification more
It is more or less.In addition, single step described in this specification, may be broken down into other embodiments multiple steps into
Row description；And multiple steps described in this specification, it may also be merged into single step progress in other embodiments
Description.
Fig. 1 is a kind of flow chart for block dissemination method that an exemplary embodiment provides.As shown in Figure 1, this method is answered
For block chain node, may comprise steps of:
Step 102, the intelligent contract for generating character string is called, the intelligence contract is used for for block chain node
Generate random character sequence.
In one embodiment, the processing logic for generating random character sequence can be previously written in intelligent contract, so that should
It automatically can be that block chain node generates random character sequence based on above-mentioned processing logic after intelligent contract is called.Due to
Processing logic on intelligent contract is disclosure, and entire treatment process is automatically performed by intelligent contract, there is no artificial
Intervene, makes it possible to ensure that the randomness of the random character sequence of generation, avoid black-box operation or cheating.
In one embodiment, random character sequence and non-fully " random ", still can meet certain preset rules, than
The value range that such as preset rules may include character quantity, character types, character, this specification are limited not to this
System.For example, it is 8 bit digitals that preset rules, which can limit random character sequence, then the random character sequence that intelligent contract generates can
" 45614381 " are thought, without generating " ax0642f0 "；In another example it is 5 that preset rules, which can limit random character sequence,
Digital+3 letters, then the random character sequence that intelligent contract generates can be " ax0642f0 ", without formation sequence
"45614381".Wherein, when random character sequence meets above-mentioned preset rules, following target character sequences is also corresponded to
The preset rules, so that random character sequence is consistent with target character sequence in structure, in form, it is ensured that random character
It is comparable between sequence and target character sequence.
In one embodiment, there are multiple block chain nodes in block chain, intelligent contract is the generation of different blocks chain node
Random character sequence should be mutually distinguishable, to avoid more than one block chain node random character sequence and target character sequence
Column match, it is ensured that the preparation block that only one block chain node generates is registered as the newest block of block chain.
Step 104, the identity information of the random character sequence and the block chain node is distributed to area in association
Block chain, wherein publication moment of the publication moment of the random character sequence earlier than target character sequence.
In one embodiment, block chain node can be traded by creating in the client of block chain, to be based on the friendship
Easily the identity information of the random character sequence and the block chain node is distributed in association on block chain, becomes block
A data in the distributed data base of chain.
It is noted that the transaction in block chain, there are points of the transaction of narrow sense and the transaction of broad sense.The friendship of narrow sense
Easily refer to the value Transfer that user issues to block chain；For example, in traditional bit coin block chain network, transaction can be with
It is that initiate in block chain one of user transfers accounts.And the transaction of broad sense refers to that one that user issues to block chain has business
The business datum of intention；For example, operator can build alliance's chain based on actual business demand, chain portion of alliance is relied on
Affix one's name to it is some it is unrelated with value Transfer it is other types of line service (for example, event prediction, business of renting a house, vehicle scheduling business,
Settlement of insurance claim business, credit services, medical services etc.), and in this kind of alliance's chain, transaction can be user and send out in alliance's chain
The service message or service request that there is one of cloth business to be intended to.Transaction in this specification should be tended to be interpreted as
Sensu lato transaction.
In one embodiment, since block chain uses distributed data base, so that being distributed to the random character on block chain
Sequence can not be tampered, so as to realize reliable record to the corresponding random character sequence of each block chain node.
In one embodiment, this specification can be such that the book keeping operation of the newest block of block chain node contention block chain weighs, and area
The book keeping operation power of other blocks on block chain it has been determined that the block chain node that can so have book keeping operation power by these be responsible for will be above-mentioned
The transaction of identity information comprising random character sequence and block chain node is written in corresponding block, and is distributed to block chain.
In other words, directly random character sequence and its identity information might not be associated by above-mentioned block chain node in step 104
Ground is distributed to block chain, it is also possible to implement the publication by other block chain nodes and operate, which block chain node tool this depends on
The book keeping operation of standby Correlation block is weighed.
It in one embodiment, can be by the random character sequence feedback to the block chain node, by block chain node
It determines the need for using the random character sequence.In one case, if it is confirmed that needing using the random character sequence, area
The random character sequence and the identity information of itself can be distributed to block chain by block chain node in association.In another situation
Under, if not approving the random character sequence being currently generated, block chain node can re-call the intelligent contract, by the intelligence
Energy contract regenerates a random character sequence, to be updated to the corresponding random character sequence of block chain node；Certainly,
If block chain is not still approved, can continue to re-call the intelligent contract, until obtaining satisfied random character sequence.
In one embodiment, the publication moment of random character sequence should be no earlier than the publication moment of target character sequence
The randomness that then will lead to random character sequence leaves a question open, and for example may be in the case where obtaining target character sequence, will be identical
Character string disguise as random character sequence and be distributed to block chain, and and non-real generated by above-mentioned intelligent contract.
Step 106, in the random character sequences match in the case where target character sequence, by the preparation of generation
Block carries out the whole network broadcast in block chain；Wherein, when the random character sequence is verified as being matched with the target character
When sequence and corresponding publication moment are that the whole network is earliest, the prepared block is registered as the newest block of the block chain.
In one embodiment, when block chain node A is received from the preparation block of block chain node B, by by the area
The corresponding random character sequence 1 of block chain node B is compared with target character sequence, that is, can determine that the random character sequence 1 is
It is no to be matched with target character sequence.If block chain node A also receives the preparation block from block chain node C, and the area
The corresponding random character sequence 2 of block chain node C is also matched with target character sequence, and block chain node A can compare random character
The publication moment of sequence 1 and random character sequence 2, to determine the random character sequence issued earlier relatively.By the above-mentioned means,
It is assumed that block chain node A determines that the corresponding random character sequence 1 of block chain node B is matched with target character sequence, and
In all random character sequences for being matched with target character sequence, when the publication of the corresponding random character sequence 1 of block chain node B
It carves earliest, that is, can determine that the random character sequence 1 meets and " be verified as being matched with the target character sequence and corresponding publication
Moment is that the whole network is earliest ", therefore the preparation block from block chain node B can be recorded as block chain by block chain node A
Newest block；Similarly, other block chain nodes can also will be remembered based on aforesaid way from the preparation block of block chain node B
Record is the newest block of block chain, is equivalent to the book keeping operation power that block chain node B contention has been arrived in block chain, realizes each area
Common recognition between block chain node.
In one embodiment, it is generated at random due to random character sequence by intelligent contract, so that between block chain node
Calculation power of the common recognition process independent of each block chain node, even if so that block chain node has grasped the whole network 51% or more
Power is calculated, the book keeping operation power in block chain still can not be controlled, the block chain node for avoiding calculation power powerful is done evil.
It in one embodiment, can be by the friendship comprising the random character sequence Yu the identity information of the block chain node
It easily is distributed to block chain, so that the random character sequence and the identity information of the block chain node are distributed in association
Block chain.Wherein, the serial number or other signature identifications that may include the transaction in the prepared block make to receive described
The block chain node of preparation block can search the transaction according to the serial number or other signature identifications from block chain, from
And the random character sequence and its publication moment are got, and the random character sequence and the publication of target character sequence are suitable
Sequence, match condition etc. are verified.
In one embodiment, the target character sequence can be distributed to the block by prophesy machine (Oracle) node
Chain.Since the data that prophesy machine node provides are considered absolutely reliable, thus it may insure the authenticity of the target character sequence.
In one embodiment, prophesy machine can obtain the target character sequence outside chain from object, such as the outer object of chain can
If can control entity device to generate the target character sequence or the outer object of chain by computer random and successively discharge at random
It is corresponded between dry bulb body, each sphere and character, thus as corresponding to the release sequence of each sphere and each sphere
Character constitutes target character sequence.
In one embodiment, the target character sequence is described for generating character string by calling by prophesy machine node
Intelligent contract and generate.It generates the processing logic of character string at random as built in above-mentioned intelligent contract, thus foretells machine
Node can make it generate target character sequence at random by calling the intelligence contract.
In one embodiment, prophesy machine node can be by broadcasting target character sequence in the whole network, by having book keeping operation
The block chain node of power is distributed in block chain.In another embodiment, prophesy machine node can be defaulted as having book keeping operation power, can
Directly target character sequence to be distributed in block chain.
In one embodiment, can be issued to the block chain associated with the random character sequence freezing of assets with
Card, the freezing of assets voucher show that the block chain assets for the no less than default number that the block chain node is held are in and freeze
State；Wherein, when associated freezing of assets voucher is not present in the random character sequence, the random character sequence is judged to
It is set to invalid information.By requiring to provide freezing of assets voucher, the block chain node setting one of book keeping operation power can be fought for participation
Fixed participation threshold, excluding the block chain node of the block chain assets deficiency held, (criminal may be interim in order to do evil
Some block chain nodes for being exclusively used in participating in contention book keeping operation power are created, increase the probability for hitting target character string with this), it improves
The cost of doing evil of block chain node.
It in one embodiment, can be by random character sequence, the identity information of block chain node and freezing of assets voucher packet
Contained in same transaction, to show the incidence relation between the freezing of assets voucher and random character sequence.In another embodiment
In, the above-mentioned identity letter comprising random character sequence and block chain node can be added in the transaction locating for freezing of assets voucher
The serial number of the transaction of breath, or added in the transaction of the above-mentioned identity information comprising random character sequence and block chain node
The serial number of transaction locating for freezing of assets voucher, this depends on the distribution order between the two transaction, i.e., earlier released
The serial number of transaction may be added in the transaction of later publication.
In one embodiment, in the random character sequences match in the case where target character sequence, the money
Production freezes the corresponding block chain assets of voucher and is defrosted and gives back to the block chain node.
In one embodiment, described in the case where the random character sequence does not match the target character sequence
The corresponding block chain assets of freezing of assets voucher by from the block chain node deduct, using as participate in fight for book keeping operation power at
This.
In one embodiment, the block chain node can there is only a corresponding random character sequence, i.e., each areas
For block chain node there is only the chance of primary contention book keeping operation power, the probability that all block chain nodes strive to keep accounts power is consistent.
In one embodiment, the block chain node may exist multiple corresponding random character sequences, each random words
Symbol sequence is respectively present corresponding freezing of assets voucher；In other words, block chain node can by provide the more parts of freezings of assets with
Card helps to promote the probability that the block chain node strives to keep accounts power to obtain multiple random character sequences.Wherein, described
The corresponding any random character sequences match of block chain node, can be by the pre- of generation in the case where the target character sequence
Preparation area block carries out the whole network broadcast in block chain；Correspondingly, when the corresponding any random character sequence quilt of the block chain node
It is verified as being matched with the target character sequence and when the corresponding publication moment is that the whole network is earliest, the prepared block is registered as
The newest block of the block chain.
In order to make it easy to understand, below by taking the block chain node in block chain as an example, to the block distribution scheme of this specification
It is described.Fig. 2 is a kind of structural schematic diagram for block chain network that an exemplary embodiment provides；As shown in Figure 2, it is assumed that area
There are block chain node 21, block chain node 22, block chain node 23 and block chain node 24 etc., the block chain nodes in block chain
It can be in communication with each other between 21~24, for example may be implemented to communicate between node two-by-two shown in Fig. 2, it is also possible to which there are parts
It is needed between node by then realizing communication in the conduct of other nodes, this specification is limited not to this.Implement one
In example, block chain node 21~23 can be ordinary node, and block chain node 24 can be prophesy machine node, block chain node 21
~23 transaction issued in block chain are considered insincere, and the block chain node 24 as prophesy machine node is in block chain
The transaction of publication is considered absolute confidence.
Based on block chain network shown in Fig. 2, Fig. 3 is a kind of process for determining book keeping operation power that an exemplary embodiment provides
Schematic diagram.It, can be by such as the either block chain node in the blocks chain networks such as above-mentioned block chain node 21~24
Mode shown in Fig. 3 fights for the book keeping operation power of newest block in block chain, which may comprise steps of:
Step 302, freezing of assets voucher is generated.
In one embodiment, by taking block chain node 21 as an example: the block chain node 21 can be to the present count that itself holds
The block chain assets of volume are freezed；For example, the block chain assets that this can be preset number by block chain node 21 be transferred to it is predetermined
The freezing of assets account of justice, and obtain corresponding freezing of assets voucher.
In one embodiment, block chain node 21 can issue freezing of assets voucher to block chain, so that the money
Production is freezed voucher and is recorded into the block chain account book that each block chain node is safeguarded respectively, content is unified.
Step 304, random number word string is obtained.
In one embodiment, by taking block chain node 21 as an example: the block chain node 21 can call intelligent contract, the intelligence
Contract has pre-defined the function logic for generating random number word string, allows the intelligence contract to be based on the function logic and gives birth to automatically
At the corresponding random number word string of block chain node 21.The length of random number word string, such as random digit are constrained in intelligent contract
String can be 128 digit word strings.Since intelligent contract is published on block chain, so that function logic defined in intelligent contract
Camera bellows caused by human intervention is avoided to grasp so that it is guaranteed that the generation result for random number word string is objective, fair for public data
Situations such as making.
It is assumed that block chain node 21 corresponds to random number word string L1.Wherein, when 21 pairs of block chain node intelligent contracts generate
Random number word string it is dissatisfied when, can by repeatedly calling the intelligence contract repeatedly, until obtain the random number word string of satisfaction,
Using as above-mentioned random number word string L1.Similarly, each block chain node can be obtained by calling above-mentioned intelligent contract
Obtain corresponding random number word string.
In one embodiment, itself corresponding random number word string L1 can be distributed to block chain by block chain node 21, with
Show the corresponding relationship between the block chain node 21 and random number word string L1, and available random number word string L1
It issues moment (being characterized by timestamp).It so, can also be with even if the corresponding random number word string L1 of different blocks chain node is identical
It is compared by the difference for issuing the moment, realizes the contention and confirmation to book keeping operation power.
Step 306, number of targets word string is obtained.
In one embodiment, number of targets word string can be obtained by prophesy machine node 24, and the number of targets word string is distributed to area
Block chain；Correspondingly, each block chain node can read the number of targets word string from block chain, to obtain the target number
String.
In one embodiment, prophesy machine node 24 can be by calling above-mentioned intelligent contract, so that the intelligence contract can
With automatic and one numeric string of random generation, for example 8 digit word strings, using as above-mentioned number of targets word string.In another implementation
In example, prophesy machine node 24 can receive the incoming number of targets word string of the outer object of chain, and for example the number of targets word string can be by right outside chain
As being generated by random algorithm.
Step 308, determine whether random number word string matches with number of targets word string.
In one embodiment, each block chain node can carry out itself corresponding random number word string and number of targets word string
Compare, to determine whether the two matches；Wherein, when random number word string is identical as number of targets word string, it is possible to determine that for should be with
Machine numeric string matches with number of targets word string.
Step 310, it when random number word string and number of targets word string match, is generated to the whole network broadcast block chain link point itself
Preparation block, and receive the preparation block of other block chain node broadcasts.
In one embodiment, by taking block chain node 21 as an example: when block chain node 21 determines itself corresponding random digit
When string 1 matches with number of targets word string, which can carry out the whole network broadcast for the preparation block of generation, so that area
Block chain node 22~24 etc. can receive the preparation block.Wherein, block chain node 21 can generate this at any time
Preparation block, for example the preparation block has been generated before step 310, or can be in confirmation random number word string 1 and target
The preparation block is generated when numeric string matches, this specification is limited not to this.
By taking block chain node 22 as an example: when block chain node 22 determines itself corresponding random number word string 2 and target number
When string mismatches, which can ignore itself generated prepared block, or terminates script or prepare
The preparation block of implementation generates operation.Wherein, block chain node 22 can receive the preparation that above-mentioned block chain node 21 is broadcasted
Block.
By taking block chain node 23 as an example: when block chain node 23 determines itself corresponding random number word string 3 and target number
When string matches, which can carry out the whole network broadcast for the preparation block of generation, so that block chain node 21-
22,24 etc. the preparation block can be received.Wherein, it is wide can also to receive above-mentioned block chain node 21 for block chain node 23
The preparation block broadcast.
Step 312, it chooses newest block and block chain is written.
In one embodiment, block chain node 21~24 etc. are respectively in one block chain account book of local maintenance, each block chain
Node can determine newest block respectively, and the newest block is written in the block chain account book of self maintained, thus realization pair
The content maintenance of the block chain account book.
By taking block chain node 21 as an example: it is assumed that block chain node 21 receives the preparation block of the broadcast of block chain node 23；For
Convenient for distinguishing, it can set that the block chain node 21 itself generates prepared block B1, block chain node 23 generates preparation
Block B2.
On the one hand, block chain node 21 can test to preparation block B2, may include:
1, according to the transaction journal number for including in preparation block B2, the corresponding friendship of the transaction journal number is read from block chain
Easily and its transaction content, the transaction content include the corresponding random number word string of block chain node 23, and block chain node 21 can be with
Examine whether the random number word string matches with number of targets word string；If mismatching, prepared block B2 can be ignored.
2, if including the corresponding freezing of assets voucher of block chain node 23 in above-mentioned transaction content, then it is assumed that in the transaction
The random number word string that appearance includes is effective；Otherwise, prepared block B2 can be ignored.Certainly, freezing of assets voucher can also be by only
Vertical transaction is distributed in block chain, and its transaction journal number can be recorded in above-mentioned preparation block B2, to make
It obtains block chain node 21 and obtains the corresponding freezing of assets voucher of block chain node 23 accordingly.
3, above-mentioned transaction content includes the publication moment of random number word string, and publication moment of the random number word string should be earlier than
The publication moment of number of targets word string.
4, the random number word string that above-mentioned transaction content includes should be not applied to fight for the book keeping operation power of other blocks, such as
