It encloses.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.
First embodiment
The present invention provides a kind of cutting method suitable for block chain network, can be two or more by " grouping "
Privately owned " subnet " is established between particular network member.These " subnets " can provide two kinds of operating modes: the first is stand-alone mode,
That is self subnet, using itself independent account book, i.e. the local account book incompatible with other " subnets "；Second is shared mould
Formula, i.e. synchronized model subnet are communicated by the anchor point node of " grouping " with major network or other " subnets ", synchronous major network account book.This reality
It applies example and is broadly divided into 4 dimensions to realize, overall structure diagram is as shown in Figure 1:
S1: constructing configurable basic network, specific steps are as follows:
S11: in the configuration file of each node, can add prior concerted " grouping " information to show oneself is
The full member of the grouping.Each participation should " grouping " node need to obtain by " grouping " distribute signature file and itself
Signature file for verifying identity.Meanwhile it can be comprising respective packet manager, for configuring and finding this in each node
Other members of grouping.
S12: packet manager (Group Manager, hereinafter referred to as GM), which is mainly responsible for, is managed " grouping " network.
In two kinds of subnet operating modes being previously mentioned, when user selects stand-alone mode, generation is responsible for by GM and is belonged to
It is somebody's turn to do the wound generation block of " grouping ", and this block is synchronized to other GM in " grouping ".Note that the foundation of wound generation block need to be by
Each " grouping " negotiates to formulate, and is finally responsible for generation by a GM.
If user's selection is shared model, GM can check whether present node is anchor point.If it is, the GM is then
Message is sent to obtain current newest world state to current master network or adjacent shared model subnet immediately, and synchronous
To other nodes of " grouping ".
S2: subnet and communication, for guaranteeing the interconnection between subnet, packet manager, so that account book is synchronous:
S21:GM is created when node is established, and is the main tool for participating in and managing " grouping ".GM is in newly-increased grouping
Main function is the configuration and mutually discovery of grouping.There are mainly two types of the discovery mechanisms of GM: actively discovering and configures.Wherein actively
It was found that the network interconnection for having normally energy intercommunication between the GM of same " grouping " is required, then by including in " grouping " information
GM mark mutually find and automatically configured.Another way be then configured in all GM of " grouping " in advance it is all its
The information of his GM carries out communication and information transmitting after node is online.
Another of S22:GM functions as anchor point participation synchronization.When " grouping " is as the type for synchronizing subnet, need
There is a kind of communication mechanism, it can guarantee the isolation of " grouping " interior joint, and can guarantee that account book is synchronous.GM at this time is then
This role is served as, whenever having new block generation, for master network, GM is a common peer node, receives this area
Block；For " grouping " subnet road, GM is a point of departure, and the block of master network is propagated to all nodes of sub-network, this mistake
Vice versa for journey.The expression of image is exactly that all synchronized model subnets are all " universe " one by one, and GM anchor point is then to link this
" the worm hole " in " universe " a bit.Synchronized model subnet is very suitable to the scene for processing business process need for confidentiality.
S3: subnetwork type conversion:
S31: it when business event change or other aspect demands, needs to change existing subnetwork type, this hair is real
Apply the support that example is also provided that this respect.The change that we will discuss two kinds of directions below: the first be synchronized model subnet to
The change of self subnet will be provided 2 kinds of selections by GM at this time, and one is bifurcated modes, by the account book state in current subnet
Retain, and carry out permanent bifurcation with major network, is separately maintained by the separate subnet formed later.It is another then abandon current account book,
Form completely new separate subnet；Second of conversion is conversion of the self subnet to synchronized model subnet, and under this conversion, GM will
Existing account book, re-synchronization major network account book are abandoned in pressure.No matter that mode, rolling back action is supported.
S32: in self subnet into synchronized model subnet conversion process, may include coin system token conversion/
Token conversion.The present invention provides self defined interface to user, and the token conversion proportion for determining subnet and major network is conferred by user,
Token conversion is completed when executing network conversion by GM, and to the synchronous subnet node account book of major network, converts the process of token still
It is considered as trading.
S4: the addition of subnet node with exit:
S41: node must be by approval before some subnet is added, i.e., the access that the node possesses subnet is signed.
Node can issue to subnet arbitrary node GM and request is added at this time, synchronize node letter to other GM according to network type from GM
Breath.For being present in the node of other subnets or major network before, transformation rule is identical as subnetwork type conversion, no longer superfluous here
It states.
S42: when node needs to exit subnet, similarly, node need to initiate to apply to itself GM, by other sections of GM and subnet
Point is reached common understanding.Then will determined according to exit strategy the node purpose network be other subnets or major network, even thoroughly
Exit block chain.Such node exits that transformation rule is identical as subnetwork type conversion, and which is not described herein again.
In conclusion the cutting method advantage suitable for block chain network in the present embodiment is:
1. business is isolated: can be seen that the industry that all nodes of subnet have been isolated in this mode well from synchronized model subnet
Business rule/intelligent contract.So that non-subnet member can not install and know these rules, the business of a node in subnet is protected
Regular privacy.
2. account book is isolated: in self subnet, all-ones subnet node is completely kept apart, other than all-ones subnet
Node will be unable to know the event inside all subnets, unless GM actively provides these information as anchor point.There is independence in subnet
" world state ", and it is external inaccessible, ensure that the confidentiality of data and affairs to greatest extent, improve network security
Property.
3. improving network throughput: the broadcast domain of block chain network is limited in a subnet, reduces traditional P2P
For the phagocytosis of bandwidth in network.Different users can be divided in different " grouping " simultaneously, network struction and maintenance are more
It is convenient, flexible.
