Technical field
The present invention relates to block chain technical field, especially, it is related to a kind of extension design method of block chain.
Background technology
Block chain (B l ockchai n) refers to the technical side by going group participation mode to safeguard an authentic data storehouse
Case.The technical scheme is let on any number of nodes in system, and the data that full detail in a period of time system is exchanged are led to
Crossing cryptographic algorithm and calculate and recorded a block (b l ock), and generate the fingerprint of the block is used to link (chai
N) next area's block sum check, system is all to be participated in node to assert whether record is true jointly.
Block chain (B l ockchai n) is made up of end to end block, and each block was included in a period of time
Information or data, and be capped timestamp, be engaged togather according to the index cryptographic Hash (hash) of a upper block, most end form
Into block chain.
Block chain (B l ockchai n) realizes two kinds of records：Merchandise (transact i ons) and block (b l
ocks).Transaction is stored in real data on block chain, and block to be then some transaction of registration confirmed be when, with
And turn into a part for block chain database in what order.Transaction is to be created by participant in normal processes using system
, and block is then to be responsible for what is created by the unit for being referred to as miner.
In current block catenary system, generally only one block chain is used for storing in the Transaction Information of history, block chain
Operation be dependent on this block chain.Simultaneously, it is necessary to safeguard accounts information in addition, such as the UTXO that bit coin is used, ether mill is adopted
Traditional database technique stores extra accounts information.So the drawbacks of, is between each node it is all respective safeguard
Accounts information, rather than reached unanimously using block chain.And information is also easily tampered.
This is just in the urgent need to an individually designed state chain is stored to the information of block catenary system.This bar state chain is remained
The advantage of original block chain, while adding some exclusive characteristics so that block chain is more safe and efficient.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of extension design method of block chain, increase by a bar state chain
Safeguard account status information so that the operation of block chain is more safe and efficient.
On the one hand, the invention provides a kind of extension design method of block chain, including state chain, state chain memory block
All account status information in catenary system, state chain safeguards that state chain can be carried out to block chain to account status information
Branch's numbering, point chain, conjunction chain, parallel block of building are operated.
In further technical scheme, branch's numbering refers to that the block that state chain is directed in block chain carries out branch
Numbering；Described point of chain refers to the block of current block chain splitting into two block chains；The conjunction chain refers to two scripts point
The block chain opened is merged；The parallel block of building refers to two block chains after fractionation while building block operation.
In order to improve block chain autgmentability, in further technical scheme, if the block length of current block chain reaches
During certain threshold value, the state chain can carry out point chain and parallel build block operation.
In order to improve block chain autgmentability, in further technical scheme, if block chain number of transaction is few,
The state chain can carry out closing chain operation.
In further technical scheme, comprise the following steps：
Step 1, which is set, N number of node in block catenary system, each node can all collect state Transaction Information；State transaction comes from
In transaction block chain, it can send and merchandise to state chain when block chain of merchandising is modified to accounts information；
Step 2 host node can build new block, and be broadcast to other nodes；
Each node of step 3 verifies that the result to checking is broadcasted to the block received；
Each node of step 4 collects the voting results of other nodes, is decrypted using its corresponding public key, verifies data
Correctness；
Current ballot content is added oneself by step 5 together after after the ballot that other all nodes have been collected in step 3
Other all nodes are broadcast to after private key signature again；
The vote information that each node is forwarded in each node take-up step 4 of step 6, and carried out with its corresponding public key
Decryption, verifies the correctness of data；
Each node of step 7 collects the voting results received in step 5；The block being verified is stored, respectively
Individual node is required for being stored, and has complete data backup.
The Core Superiority of the present invention is to extend traditional block chain technology, and creative proposes state chain
Concept, increase state block chain account status information is safeguarded.Simultaneously in order to increase the autgmentability of block chain, increase
Add point chain of block chain and close chain operation.Block catenary system is allowd conveniently to carry out elastic increase and decrease for system pressure.
By block point chain when block catenary system processing pressure is big, different branches is distributed to different machines and goes processing；Work as block
When catenary system pressure is small, to save block catenary system resource, block chain can be merged, reducing need to be to be processed
Machine.Block catenary system resource can be saved by closing chain, the operation of point chain can by by block branch by the pressure of block catenary system
Power is distributed on different machines, to reach the effect of load balancing.
Due to adding state chain, transaction block chain needs to lock transaction when being modified account status.
The state that others are merchandised to change certain account, can first attempt to obtain transaction lock.If can get lock can just modify, repair
Lock will be discharged after the completion of changing again；It if lock can not be got, can be waited, just can after the completion of the trading processing of other lockings
Handled.So, be not in multiple by the security for the guarantee block catenary system state for locking operation meeting high degree
Accounts information entanglement phenomenon transaction is handled simultaneously when.

Embodiment
In order to be better understood from technical scheme provided in an embodiment of the present invention, also technology preferably with the embodiment of the present invention
Scheme is contrasted, and implementation of the prior art is simply introduced by way of example first below.
The present invention has initiated state chain, while the particularity also directed to state chain has created following several critical technologies
, to ensure the efficient and safe of this state chain.Key technology mainly has following four：State chain component numbering model；State
Chain point chain operation；State chain builds block parallel, and block chain closes chain.Next this four key techniques are illustrated respectively.
1. state chain component numbering model
One label is set to each block chain component, initial branch is 0.00 and 01 are reformed into after bifurcated, and with such
Push away the numbering that each branch is set.The branching diagram of so whole block chain appears as the structure of a binary tree, such as Fig. 1
Shown, branch's increase that so new block can only be on leaf node, non-leaf nodes is all point of the history block of storage
Branch.
2. state chain point chain operation
For the expansion block chain link point of elasticity so that block chain can set up block parallel, so present invention design
The operation of a kind of point of chain, by the branch of a block chain splits into 2 chains.Block point chain operation can occur arbitrary
On moment and any branch.The present invention devises a kind of according to a block chain component length progress point chain.Specific operating procedure
It is as follows：
Often wheel build block end need storage when, judge whether current branch reaches the threshold value of division.If reaching, it can work as
On the basis of preceding block, by current branch split into 2 branches, so new branch start 2 blocks all can be with current block
It is used as Pre_Hash.Meanwhile, new branch can carry out building block parallel.If not up to the threshold value of division, will not enter line splitting.As schemed
Shown in 2.
3. state chain builds block parallel
Because the branch after division can build block parallel, this is accomplished by the transaction that new transaction is distributed to different branches
In caching.The distribution that transaction distribution is traded using the mechanism of similar poll, ensures that each branch's number of transaction is near with this
Average, branch merchandises barrel mould as shown in figure 3, the number of transaction of each barrel of inside is almost identical.Block failure is built in certain branch
Afterwards, Transaction Information will not be lost, and transaction can be write back to again in the transaction caching of the branch, participate in building block next time.
4. branch merges
When block chain number of transaction is few, some branches can be merged, at this time can be with to save system resource
The block chain of script bifurcated is merged.
Because there is respective branch number in each branch, so the first two father's block that block after merging has
Hash values.So it is accomplished by the head of block increasing an extra Pre_Hash field.During acquiescence, block can only be used
One Pre_Hash, only the meeting positioned at the block for closing chain position is by the cryptographic Hash of two father's blocks.Branch number after merging
It for the merging of two parent branch, can so ensure the unique of branch number, will not repeat.
Examples of implementation
Assuming that there is 4 nodes in block catenary system, respectively A nodes, B node, C nodes, D nodes, each node are initial
All in No. 0 branch.
1) A nodes, B node, C nodes, D nodes all constantly receive the account status information that transaction block chain is sent.
2) state chain enters according to the information received and constantly built in the circulation of block.
3) when number of blocks reaches threshold value a, ABCD nodes can all carry out the division of block chain.Each node branch is all
Become 2 branches：00 and 01.
4) can now be produced in system 2 transaction buckets be respectively used to 00 and 01 Liang Ge branches build block operation, respective point
Branch can handle respective transaction, will not produce entanglement.
5) if necessary to which 00 and 01 Liang Ge branches are merged, then new block can be used as two Pre_ of oneself using 00 and 01
Hash.It is 0001 with stylish block branch number.This block number is also unique, it is impossible to repeated.
So, system constantly repeats said process, constantly receives transaction, carries out a point chain, closes chain and builds block operation, nothing
The reciprocal of limit goes down.
Specific case used herein is set forth to the principle and embodiment of the present invention, and above example is said
The bright method and its core concept for being only intended to help to understand the present invention；Simultaneously for those of ordinary skill in the art, foundation
The thought of the present invention, will change, in summary, this specification content is not in specific embodiments and applications
It is interpreted as limitation of the present invention.
