Specific embodiment
Inventor finds current block chain under study for action the prior art has at least the following problems: block chain is difficult to carry out fragment.
Fragment is by a technology of information aggregate decentralized processing, it extends block chain by way of increasing node
It is whole to calculate power and storage power, the especially significant effect in the case where information aggregate is more huge.However the account book of traditional block chain
It is chain structure, production node is reciprocity each other, and the block content of generation also needs the whole network to confirm jointly, which dictates that each production
Node will respectively safeguard the account book of complete set, while also carry out the verifying of All Activity content, therefore be difficult to tradition
Block chain carries out fragment.
It is not perhaps problem when userbase is little in the short time if not carrying out fragment to traditional block chain, but long-term
From the point of view of or userbase it is huge when, will lead to destructive consequence.Destructive consequence is mainly reflected in following two aspect:
First aspect: the overall performance of traditional block chain is not able to satisfy actual needs more.Whether transaction verification or
Block production, both depend on production node single-point performance, increase node can only increase Safety Redundancy, not can increase calculate power and
Store power.This means that the performance boost of traditional block chain is extremely limited, when userbase is increasing, number of transaction is increasingly
When more, trading the case where blocking will be increasingly severe.
Second aspect: the production node increasingly centralization of traditional block chain.Over time with the growth of user, account
Book data and relevant status data will more expand, and the requirement of storage power and calculation power to production node is also higher and higher,
In Moore's Law close in the case where failure, the node produced of having the ability will be fewer and fewer.This is carried on the back with decentralization principle
Road and speed, be equivalent to and theoretical foundation existing for traditional block chain be negated.
In view of this, some technical staff, which are directed to traditional block chain, has carried out sliced trial, but generally existing operation
Complicated, the problems such as stability is low, palliative.It traces sth. to its source, under the premise of guaranteeing decentralization principle, traditional block chain
It with allocation methods is conflicting in principle to the chain weave mode of block.
To solve the above-mentioned problems, the embodiment of the present application provides a kind of method for generating block chain, comprising: reception comes from
The transaction request for the creation subchain that the promoter of father chain sends；The transaction request is verified, the generation when being verified
Combine block, first block of the combination block as the subchain；The combination block includes father chain's information and subchain
Information, the combination block include chain address and block type, and the chain address identifies the address of the subchain, the block class
Type is identified as combination block type；The corresponding subchain of one combination block；Subchain is as derived from the combination block on father chain
One new chain；The combination block is verified, updates the data of the combination block to block chain when being verified
In.
The method provided by the embodiments of the present application for generating block chain is spread out by generating combination block, combination block on father chain
Life obtains subchain, so that tree structure block chain is constituted, in order to realize block chain fragment.The block chain generated due to this method
It is peer-to-peer between middle difference chain, thus, which meets central tenet.It is every in the block chain generated due to this method
Chain is parallel, so that the block chain can be with infinite extension, to improve the overall performance of block chain.In addition, working as the party
The chain that the block chain that method generates includes is more, then calculation power and storage power needed for average every chain are fewer, so that performance
Common node can also act as production node, and then solve the problems, such as production node increasingly centralization.
In order to enable those skilled in the art to better understand the solution of the present invention, below in conjunction in the embodiment of the present invention
Attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is only this
Invention a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Embodiment one:
Referring to Fig. 1, which is the flow chart of the method for the generation block chain that the embodiment of the present application one provides.
Generation block chain method provided by the embodiments of the present application includes:
S101: the transaction request for the creation subchain that the promoter from father chain sends is received；
The promoter of father chain refers to the user on father chain.Wherein, promoter can send multi-exchange request, due to
Creation subchain is a kind of special transaction, thus, promoter, which must have certain condition, can just create subchain.
The transaction request of creation subchain includes the destination address and operation code of user's signature, transaction.Wherein, the target of transaction
Address can be sky, it is possible to have specific format；Operation code of the operation code different from other transaction requests.
Father chain refers to the chain that can derive subchain.
Subchain refers to by the derivative obtained new chain of existing chain.
Father chain and subchain are two chains of equity, and subordinate relation is not present between father chain and subchain.
It should be noted that first chain in the tree structure block chain including a plurality of connected chain is known as root chain, and
Root chain is to be automatically created by production node according to initiation parameter, and other chains are then the transaction according to corresponding creation subchain
What request was created.
As an example, when block chain only includes root chain, then S101 can be with specifically: when the wound that the promoter of root chain sends
The transaction request of subchain is built, then root chain receives the transaction request of creation subchain as father chain.
As an example, then S101 can when block chain includes a root chain and first subchain as derived from root chain
With are as follows: if the promoter of root chain sends the transaction request of creation subchain, root chain is asked as the transaction that father chain receives creation subchain
It asks；If the promoter of first subchain derived from root chain sends the transaction request of creation subchain, the first strip derived from root chain
Chain receives the transaction request of creation subchain as father chain.
S102: verifying the transaction request, and combination block, the combination block conduct are generated when being verified
First block of the subchain；The combination block includes father chain's information and subchain information, and the combination block includes chain
Location and block type, the chain address identify the address of the subchain, and the block type is identified as combination block type；One
Combine the corresponding subchain of block；Subchain is a new chain as derived from the combination block on father chain；
Verifying to the transaction request of creation subchain is carried out by the production node on father chain, verification process specifically:
After production node receives the transaction request of creation subchain, user's signature need to be verified, judges whether the promoter reaches creation subchain
Condition then continue to execute subsequent action if the verification passes；If authentication failed, the creation process of subchain and clear is interrupted
Except transaction request.
The tie point that block is father chain and subchain is combined, thus, combination block is located on two chains of father chain and subchain simultaneously,
And father chain and subchain recognize the legitimacy of the combination block.In addition to root chain, first block of any bar chain is combination region
Block.
Block type is the classification for identifying block, includes normal block and combination block in block chain, wherein group
The block type for closing block is combination block type, and the block type of normal block is normal block type.When reading block chain
In either block when, can judge that the block is combination block or normal block according to the block type of the block, if
It is combination block, then knows that the block is located on two chains.
Chain address be for the chain where unique identification block, when read block chain in either block when, being capable of basis
The chain address of the block determines the position of the block.
As an example, S102 can be with specifically: when receiving the transaction request of creation subchain, firstly, the life on father chain
The condition whether promoter that verifying sends transaction request is reached creation subchain by node is produced, if the promoter reaches creation
The request of chain, then be verified；Then, production node generates combination block according to the request of creation subchain, and it is same to combine block
When be located at father chain and subchain on.
S103: verifying the combination block, updates the data of the combination block to area when being verified
In block chain.
Verifying is carried out to combination block and refers to whether verifying father chain recognizes the legitimacy of combination block.
It includes: the tail portion that combination block is connected to father chain that block, which will be combined, and updated to block chain；The letter of block will be combined
Breath is added in the account book of father chain.
As an example, S103 can be with specifically: after the production node on father chain generates combination block, need to verify father chain
Whether recognize the legitimacy of the combination block, if father chain recognizes the legitimacy of the combination block, which is connected
To father chain tail portion and the information for combining block is added to father chain account book in.
Method based on the generation block chain that above embodiments provide, in order to improve the efficiency exchanged visits between different chains, this
Application embodiment provides a kind of method for generating block chain, is described in detail with reference to the accompanying drawing.
Embodiment two:
Referring to fig. 2, which is the flow chart of the method for the generation block chain that the embodiment of the present application two provides.
It is provided by the embodiments of the present application generate block chain method include:
S201 is identical as S101 content, and details are not described herein.
S202: verifying the transaction request, and the subchain that the father chain is currently included is obtained when being verified
Number.
To transaction request carry out verifying it is identical as the related content of " being verified to transaction request " in S102, herein not
It repeats again.
The number for the subchain that father chain is currently included refers to the number that the subchain of completion has been created on father chain.
S203: when the number of the subchain is less than preset threshold, the combination block is regenerated, the combination block is made
For first block of the subchain；The combination block includes father chain's information and subchain information, and the combination block includes chain
Address and block type, the chain address identify the address of the subchain, and the block type is identified as combination block type；One
The corresponding subchain of a combination block；Subchain is a new chain as derived from the combination block on father chain.
Preset threshold refers to the total number of derivative subchain on preset father chain, and for judging that the subchain on father chain is
It is no to reach preset subchain total number.For the ease of the exchanging visit between different chains, can preset according to actual needs
Preset threshold.
If the number for the subchain that father chain is currently included is less than preset threshold, continue to create subchain according to transaction request；If
The subchain number that father chain is currently included is more than or equal to preset threshold, then determines that the transaction request for sending creation subchain is invalid, and to
The subchain quantity that promoter sends the father chain has reached the notice of the upper limit.
Since the address of the upper subchain of father chain is continuous, and it is unique, thus can use the ground of subchain on father chain
Location obtains the subchain number that father chain is currently included.
For example, then the address number of subchain can be 1 to 255 when preset threshold is 255.If the current upper subchain of father chain
The maximum value of address is 200, it is possible to determine that 55 chains can also be created by going out the father chain, then continues to create subchain according to transaction request,
In order to generate the subchain that address is 201；If the maximum value of the current upper subchain address of father chain is 255, it is possible to determine that go out the father chain
Subchain number have reached preset threshold, then determine send creation subchain transaction request it is invalid, while to promoter send should
The subchain quantity of father chain has reached the notice of the upper limit.
Combination block is identical as the related content for " combining block " in S102, and details are not described herein.
S204: the production node positioned at the preset number of the father chain jointly verifies the combination block, when testing
The ratio for demonstrate,proving the production node that the production node that the combination block passes through accounts for the preset number is greater than or equal to preset ratio
When, then it verifies the combination block and passes through, the data of the combination block are updated into all production nodes.
Preset number can be preset number.
Preset ratio is preset ratio.
It can be with to the detailed process verified of combination block are as follows: firstly, generating the production node of combination block will combine
The information for including in block is broadcasted to the upper other production nodes of father chain；Then, the upper other production nodes of father chain will be tested respectively
The legitimacy of card combination block；Finally, summarizing the verification result of the upper all production nodes of father chain, if it exceeds the life of preset ratio
Produce node think the combination block be it is legal, then be verified.
By the data for combining block be updated to it is all production nodes refer to by combine block in data be recorded on father chain
The corresponding account book of each production node in.
As an example, when preset number be 50, and preset ratio be 50% when, the detailed process of S103 is: firstly, generate
The production node for combining block broadcasts the data information for combining block to upper other the 49 production nodes of father chain；Secondly, 50
Production node separately verifies the legitimacy of combination block；Then, the verification result for summarizing the upper 50 production node of father chain, obtains 40
A production node think combine block be it is legal, due to 40 produce nodes be father chain it is all production nodes 80%, thus
It is verified；Finally, the data for combining block are recorded in its corresponding account book by 50 production nodes.
The method provided by the embodiments of the present application for generating block chain needs first to judge the father chain before generating combination block
Whether the number for the subchain being currently included is less than preset threshold, if so, generating block.This method by setting according to actual needs
Determine preset threshold, the scale of block chain is limited, to improve the efficiency exchanged visits between different chains.Moreover, this method passes through father
The legitimacy of the production node mutual authentication combination block of preset number on chain, to guarantee in account book the consistency of data and effectively
Property, to realize the generation for the case where avoiding due to part of nodes failure or dolus malus.
It should be noted that the chain address of each subchain has uniqueness, and different from the chain address of father chain, because
And when reading a certain block in block chain, the position of the block can be determined according to the chain address of the block.
In order to guarantee the uniqueness of chain address and improve using chain address lookup and position the efficiency of block, the application is implemented
Example provides a kind of addressing method of chain address:
Firstly, determining the chain address of root chain.Since root chain is to be automatically generated by production node according to initiation parameter, because
And to avoid confusion, the chain address of root chain is addressed to 0；
Secondly, determining the chain address of the subchain of root chain.In order to distinguish the different subchains of root chain, the subchain of root chain is compiled
When location, address code is since 1；
Then, it is determined that the chain address of remaining chain.For the ease of the quick positioning and lookup of block, the chain address of remaining chain
Addressing will using colon as connection level separator.
Understanding for the ease of those skilled in the art to the addressing method of chain address provided by the embodiments of the present application, is provided below
