Block chain to need to provide feasible implementation, and this directed acyclic graph by sub-block chain mode tissue data
Type block chain, can be huge with organization and management content, complicated classification, the complicated data of logical relation between data, compensate for existing
Having block chain can not meet the demand organized and managed to multifarious data.
Embodiment two
In current established block chain, or formed by the method and step performed repeatedly shown in Fig. 3 it is oriented
In acyclic pattern block chain, can have any one or two kinds in the block unit of following form：
Block unit is made up of at least two sub-blocks and father's block, that is, correspond to block unit as shown in Figure 1a；
Block unit is made up of a sub-block and two or more father's block, that is, correspond to block unit as shown in Figure 1 b；
Wherein, each sub-block in above-mentioned block unit is designated as a son wound generation block, the of the sub- wound generation block
Three block volume datas have identical classification with the block volume data of block in the sub-block chain where the sub- wound generation block.
Wherein, the 3rd described block volume data, is defined as in current established block chain, any sub- wound generation block
In block volume data；Sub-block chain where son wound generation block is it is understood that using the sub- wound generation block as initial block
The sub-block chain of formation.
Based on sub- wound generation block, and sub-block chain concept, as shown in figure 5, for provided in an embodiment of the present invention oriented
The generation method flowchart 2 of acyclic pattern block chain, the method can be considered the specific implementation of embodiment of the method shown in Fig. 3.
As shown in figure 5, the generation method of above-mentioned block chain comprises the following steps：
S510, collects the information from information source and is packed into the first block volume data of new block.Step S510 with
The content of step S310 is identical.
S520, by the 3rd block body number of the first block volume data and each sub- wound generation block in current established block chain
According to comparing, father block of at least one block as new block is chosen.Step S520 can be considered the refinement step of step S320
Suddenly.
Before the implementation procedure for being specifically described this step, first to the pass between the block volume data of each block in block chain
Connection property type is illustrated.
In established directed acyclic pattern block chain, the block volume data in two adjacent father's blocks and sub-block
Its content is association, and the block volume data content described in sub-block can be the refinement number of block volume data in father's block
According to, or the spread data of block volume data (can carry out area as corresponded to the block volume data in block according to the time in father's block
The extension of block), and or the data with the relevant property in business of block volume data in father's block.
By taking Fig. 6 as an example, the relevance of the block volume data in father's block adjacent to two and sub-block is solved
Release as follows：
A certain enterprise is carried out using the block chain in the present embodiment in directed acyclic pattern structure to the business of its branch company
Data organization and management, the enterprise set up block b0 " amusement ", block using block a0 " group " as wound generation block under " group "
Industry sub-block b1 " food and drink ", block b2 " real estate " three arranged side by side, further includes block c0 " trips under " amusement " industry
The skill Room " and the specific items to manage of block c1 " Internet bar " two.In the data management of the enterprise, " amusement " can be considered " game room "
The upper data of " Internet bar ", " group " can be considered the upper data of " amusement ", " food and drink ", " real estate "；And block c4 " projects
Competitive bidding ", block c5 " project financing ", block c6 " project construction " can be considered under " real estate " classification have malleable data simultaneously
Form is deposited, generic data are can be considered.Certainly, if not existing refinement between the multiple bottom data of a certain upper data
Necessity of classification, then the corresponding block of these the next data can also be formed the area of single-chain by the extension relation between data
Block chain structure, now, also can the corresponding block volume data of these blocks be called generic data.
In the block chain shown in Fig. 6, also there is one kind can not be closed between block volume data in each block of category division
Connection property situation, i.e., by block c1 " Internet bar ", block c3 " dining room ", the block unit of block d1 " supermarket " form in, " Internet bar "
" dining room " is neither the same type data of " supermarket ", nor the upper data of " supermarket ", but " supermarket " and " Internet bar " and " eats
All there is operational contact between the Room ", such as provide such as beverage, snack commodity, this relevance to " Internet bar " and " dining room "
Business association is accomplished by be divided.
So-called business association refers in the present embodiment, between two object datas, first with regard to not being on content type
The data of same type, secondly, without the relation for being each other upper and lower data, finally, two objects between two object datas
There is operational association between data.
As shown in Figure 6, in the block chain of directed acyclic pattern structure, the sub-block chain of multiple linears is contained,
And " real estate ", " amusement arcade ", " Internet bar ", " supermarket " these blocks are exactly the wound generation block of these sub-block chains, in order to distinguish
The wound generation block of most original, it is sub- wound generation block that can call it as.
For example, sub-block chain where " real estate " corresponding block is contained in the block body of block c4 to block c6
Various data, in actual applications, some special datas can be stored in sub- wound generation block, for example, being directed to " real estate " conduct
Overall description of block volume data etc. of each block in sub-block chain where son wound generation block, it is of course also possible to by the sub- wound
Generation block is stored as a normal block in the sub-block chain needs the data of storage." amusement arcade " and " Internet bar " correspondence
Block where sub-block chain in block shown with ellipsis.
The block chain of whole directed acyclic pattern structure can constantly extend with actual application, extend and there are two kinds of feelings
Condition, one kind is extended after some sub-block chain, and another kind is to produce new son wound generation block, so as to new son can be formed
Block chain.
Above content to the block volume data of each block is respectively generic association, upper and lower position data correlation and business
Association is illustrated respectively, meanwhile, also reaffirm sub-block chain concept in actual applications.
On this basis, by the 3rd area of the first block volume data and each sub- wound generation block in current established block chain
After block data are compared, following block can be defined as father's block of new block：
Generation block is created with the son corresponding to the 3rd block volume data that the first block volume data has business association, or
The block of the end of the sub-block chain where sub- wound generation block.
For example, not being current shape including the block chain that the remaining block including block d1 " supermarket " is constituted in Fig. 6
Into block chain, when the first block volume data is the related data on " supermarket ", can will with block d1 " supermarket " have industry
Son wound generation block c1 " Internet bar " of business relevance is defined as father's block of block d1 " supermarket ", or sub- wound generation block b1 " is eaten
The block c3 " dining room " of the end of sub-block chain is defined as father's block of block d1 " supermarket " where drink "；
And/or,
Generation block can be created as the son corresponding to the 3rd block volume data of the upper data of the first block volume data,
Or the block of the end of the sub-block chain where sub- wound generation block.
For example, not being current shape including the block chain that the remaining block including block d1 " supermarket " is constituted in Fig. 6
Into block chain, can will be the upper digit of " coffee shop " when the first block volume data is the related data on " coffee shop "
According to " food and drink " corresponding to son wound generation block b1 " food and drink " be defined as father's block of block c8 " coffee shop ", or by sub- wound generation
The block c3 " dining room " of the end of sub-block chain is defined as father's block of block c8 " coffee shop " where block b1 " food and drink ".Fig. 7
It is the block that sub- wound generation block b1 " food and drink " and block c3 " dining room " are formed collectively as father's block of block c8 " coffee shop "
Chain aspect graph.
In addition, the first block volume data is contrasted with the degree of correlation of the 3rd block volume data for convenience, can formed in advance
After the block volume data of each block, the classification information that will be formed according to the content of the block volume data of block is believed as control
Breath storage is in the block head of current block.When by the first block volume data and current established block chain Zhong Gezichuan generation area
When the content of the 3rd block volume data of block is compared, the class that will directly can be formed according to the content of the first block volume data
Other information, compares with the classification information formed according to the content of the 3rd block volume data, so that it is determined that with the first block
Volume data is generic or there is the 3rd block volume data of business association for position data thereon or with it.Then according to above-mentioned
Method selects father's block of new block.
