Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
As shown in Figure 1-3, in the first embodiment of the invention, providing a kind of block chain accounting nodes choosing for being associated with related chain Selection method, which is characterized in that the described method includes:
Obtain the first block cryptographic Hash of the first Correlation block of the first related chain outside this block chain network;Described first Correlation block is the newest block of the confirmation of having known together on the described first related chain;The first block cryptographic Hash is described first The block cryptographic Hash of Correlation block;
According to the first block cryptographic Hash, the book keeping operation Kazakhstan that this block chain network new round selects constituency block book keeping operation power is solved It is uncommon;
According to the book keeping operation Hash and preset first mapping relations, the determining note to be selected to match with the book keeping operation Hash The accounting nodes that account node is kept accounts as this block;First mapping relations are that the book keeping operation Hash and accounting nodes reflect Penetrate relationship.
Optionally, the first block cryptographic Hash is this block cryptographic Hash stored on first Correlation block, optional , the first block cryptographic Hash is to carry out Hash to the entirety or block head of first Correlation block to solve operation acquisition 's.
The Kazakhstan that this example passes through the newest block of the first related chain (such as bit coin network) outside acquisition this block chain network Uncommon value, and according to Hash operation as a result, determining that the ownership of the new block book keeping operation power of this block chain network, the pure calculation power of reduction compete area Block chain network (such as bit coin) needs to consume higher calculation power, reduces social resources waste.
Optionally, selection and more matched at least two accounting nodes of book keeping operation Hash, and power competition is calculated by it, so as to Obtain the accounting nodes of this block book keeping operation.
As shown in figure 3, in the present embodiment, it is described according to the first block cryptographic Hash, it is new to solve this block chain network One wheel selects the book keeping operation Hash of constituency block book keeping operation power, further includes:
In a block period of the described first related chain, in response to newest described the first of the described first related chain Correlation block does not change, carries out secondary Hash operation by the book keeping operation Hash of the upper block to this block chain network, obtains Obtain the book keeping operation Hash of next block of this block chain network.
In practical applications, the associated related chain of optional bit coin or ether mill as this block chain network;It can Choosing, the block of related chain generates the block generation period frequency that period frequency is higher than this block chain network, then Hash pair of keeping accounts Answer an associated block cryptographic Hash.Optionally, the block of related chain generates the area that period frequency is lower than this block chain network Block generates period frequency, then a block cryptographic Hash corresponds to multiple book keeping operation Hash.
By taking bit coin as an example, average every 10min generates a new block, and the block of this block chain network generates the period Frequency is higher than bit coin network, for example, average 1min generates a new block, at this point, each block of bit coin network is breathed out Uncommon value will generate 10 book keeping operation Hash;
Optionally, this 10 book keeping operation Hash be to bit coin block cryptographic Hash respectively time and again solve cryptographic Hash obtain. The latter book keeping operation Hash is obtained by carrying out Hash operation to previous book keeping operation Hash.
Optionally, first book keeping operation Hash is the block cryptographic Hash of bit coin network;
Optionally, first book keeping operation Hash is the cryptographic Hash of the block cryptographic Hash of bit coin network;
Optionally, in a block period of a bit coin network, the latter book keeping operation Hash has previous book keeping operation to breathe out It is uncommon to be obtained after Hash operation.
In the present embodiment, described according to the book keeping operation Hash and preset first mapping relations, it is determining with the book keeping operation The accounting nodes that the accounting nodes to be selected that Hash matches are kept accounts as this block, further includes:
According to the book keeping operation Hash, determining at least one optional accounting nodes to match with the book keeping operation Hash;
According to the competition results of the optional accounting nodes, the accounting nodes of this block book keeping operation are determined.
In an optional case, the first mapping relations are that accounting nodes and book keeping operation Hash foundation mapping are closed by mapping table System.For example, accounting nodes include 10, all possible cryptographic Hash is divided into 10 parts averagely or unequal, according to book keeping operation Hash determines the book keeping operation power ownership of this book keeping operation.For example, accounting nodes include 16, through judgement book keeping operation Hash under 16 systems First, determine book keeping operation power.
In another example accounting nodes include 100, by the first mapping relations, 20 accounting nodes are selected, then 20 Accounting nodes are at war with calculating power competition or other competitive ways to book keeping operation power.It is noted that in order to save calculation power, Can choose less accounting nodes to be at war with, at the same also can be avoided the interim delay machine of selected accounting nodes and cannot be into Row book keeping operation operation.
In the present embodiment, described according to the book keeping operation Hash and preset first mapping relations, it is determining with the book keeping operation The accounting nodes that the accounting nodes to be selected that Hash matches are kept accounts as this block, further includes:
According to the first place of the value of the book keeping operation Hash, the accounting nodes of this block book keeping operation are determined;Wherein, the note Account Hash is M system, and it is M parts that the accounting nodes, which are preassigned,.
For example, the value of the book keeping operation Hash indicates that accounting nodes are assigned 16 parts and label, according to book keeping operation with 16 systems The first place of the value of Hash determines the accounting nodes of this block are which parts in 16 parts of original.
It is noted that optional, first Correlation block is the newest block on the described first related chain;It is optional , choose the accounting nodes kept accounts with the book keeping operation most matched accounting nodes of Hash as this block.
In the present embodiment, first Correlation block is the N of the preamble of the newest block on the described first related chain A block.
Optionally, the N=6.
Since existing bit coin network is after six confirmations, it is ensured that transaction is not gone back on one's word, so, optionally, First Correlation block can choose the 6th block relatively closed on.
In the present embodiment, the firstth area of the first Correlation block of the first related chain obtained outside this block chain network Block cryptographic Hash, further includes:
The master link point of at least three heterogeneous networks on chain related to described first is communicated, and obtains at least three not With the main chain block cryptographic Hash of the first Correlation block of the main chain node of network;Wherein, the main chain number of nodes is odd number It is a;
In all main chain block cryptographic Hash, the first block Hash described in the most conduct of number of iterations is chosen Value.
