Specifically, consensus rules intelligence contract module 200 is mainly for realizing dynamic renewal book keeping operation order, it is determined that currently
Block accounting nodes.The quantity and book keeping operation order of node of knowing together are known together using consensus rules intelligence contract.The common recognition
Regular intelligence contract is set by keeper's (i.e. monitoring party).The present embodiment does not limit the interior of specific consensus rules intelligence contract
Hold.Keeper can be configured according to the demand of actual alliance's chain, existing rule can equally be entered according to actual conditions
The following information of row adaptation etc., such as consensus rules intelligence contract specified in more detail：
1st, there is the i.e. newest common recognition node white list of the node listing of book keeping operation authority.
2nd, the book keeping operation stand-by period most long is that current block accounting nodes must be remembered within the book keeping operation stand-by period most long
Account behavior.
3rd, the determination mode of current block accounting nodes is the mode that is ranked up of utilization hash values of the present embodiment middle finger
Determine current block accounting nodes.
4th, requirement of other information relevant with consensus rules such as some alteration rulers etc..
Wherein, each corresponding hash values of node of knowing together in the common recognition node white list after updating are obtained in the present embodiment, is pressed
Hash values are ranked up according to predetermined ordering rule obtain order of keeping accounts.Can determine the white name of common recognition node after updating first
The common recognition node for increasing in list or deleting, then calculates its corresponding hash value, if increasing common recognition node, in book keeping operation order
In the increased common recognition corresponding hash values of node are added to correspondence position according to predetermined ordering rule, if deleting node of knowing together,
Corresponding common recognition node will be then deleted in order of keeping accounts, and will be sequentially adjusted in other corresponding book keeping operation order of common recognition node.Also may be used
To be the common recognition node for determining to increase or delete in the common recognition node white list after renewal first every time, its correspondence is then calculated
Hash values, transferring other common recognition nodes hash values, hash values are ranked up according to predetermined ordering rule finally and are obtained
Book keeping operation order.Can certainly calculate each corresponding hash values of node of knowing together in the common recognition node white list after updating, according to
Predetermined ordering rule is ranked up to hash values and obtains order of keeping accounts.The present embodiment is not defined to this.As long as can be with root
The corresponding book keeping operation order of each common recognition node is worth in the common recognition node white list after renewal according to hash.
Predetermined ordering rule in the present embodiment can be the order according to hash values from big to small, or hash values from
It is small to big order etc..The present embodiment is not defined to predetermined ordering rule.As long as the predetermined ordering rule can be recognized
Can, the determination of book keeping operation order is carried out according to the predetermined ordering rule every time.It is just suitable according to this after book keeping operation order is obtained
Sequence is kept accounts in turn, and after previous block accounting nodes complete to keep accounts, latter common recognition node is just current block accounting nodes,
Kept accounts.
Further, the present embodiment can not perform book keeping operation behavior for a long time in order to prevent a common recognition node for failure,
So as to influence whole efficiency.Preferably, consensus rules intelligence contract module can include：
Current block accounting nodes determining unit, for when previous block accounting nodes complete keep accounts after, will be previous
The book keeping operation order of block accounting nodes adds 1 determination current block accounting nodes；
Judging unit, for whether starting note in the given time using overtime rule judgment current block accounting nodes
Account, if not starting, the new current block accounting nodes of 1 determination is added by the book keeping operation order of current block accounting nodes.
Specifically, time-out rule sets a scheduled time, the wait book keeping operation time as most long scheduled time.If working as
Preceding block accounting nodes are not carried out book keeping operation behavior within the scheduled time, then postponed to next common recognition section according to book keeping operation order
Point, as current accounting nodes.
Further, in order in ensureing the rule in consensus rules intelligence contract each rule can comply with the need of practical application
Ask.Consensus rules intelligence contract module can also include in the present embodiment：
Consensus rules change unit, for changing the rule in consensus rules intelligence contract and synchronous after reaching common understanding
Each participant in alliance's chain；Wherein, rule includes the regular and predetermined ordering rule of time-out.
Wherein, the present embodiment is not defined to the regular particular content in consensus rules intelligence contract.Keeper
Consensus rules intelligence contract can be modified, to meet the demand of practical application.And because formula rule is for this
The normally operation of system is most important, therefore the reliability that can just ensure to change that also has to obtain knowing together to its modification.I.e.
Consensus rules modification in itself also should be by the common recognition of alliance's chain.
Specifically, when monitoring party be keeper need change consensus rules intelligence contract in it is regular when, monitoring party is first
Calling consensus rules intelligence contract carries out rules modification, and the action needs to be reached common understanding under consensus rules before.Reach altogether
After knowledge, each participant will be synchronized to the change of this rule, and new consensus rules have just accomplished the whole network confirmation.By this side
Formula, alliance's chain can at any time additions and deletions node, modification consensus rules, realize high flexibility and high reliability.Realize common recognition node
Identity, the function managements such as common recognition, privilege feature can be submitted to.
Common recognition confirms module 300, for being total to block data after current block accounting nodes submit block data to
Know and confirm.
Wherein, common recognition validation testing conventional at present is to carry out common recognition confirmation to block data using PBFT common recognition algorithms.
But PBFT common recognition algorithms can not dynamically recognize current new book keeping operation order of common recognition node etc..I.e. can not be dynamic
Obtain common recognition node white list.In order to realize that dynamic PBFT common recognitions algorithm reads common recognition node listing in real time, to solve tradition
Centralization mode, it is impossible to ensure the problem of security and uniformity.Preferably, common recognition confirms that module is specially in current block
After accounting nodes submit block data to, according to the common recognition node white list after renewal, algorithm is known together to block using dynamic PBFT
Data carry out common recognition confirmation.That is dynamic PBFT common recognition algorithms realize the Error Tolerance of (n-1)/3n, and n is node total number amount.
Specifically, the implementation process of dynamic PBFT common recognition algorithms can be as follows：
1st, go out this three information of block people public key, current height, current round to determine according to a upper height block
Settled preceding round's goes out block people.It is non-go out block people enter the pre-prepare stages.Go out block people packing transaction and produce new block simultaneously
Broadcast pre-prepare message (comprising block hash and go out block people with oneself private key to the signature of block hash), so
After be directly entered the prepare stages.
2nd, the pre-prepare stages.It is non-go out block people receive out block people broadcast pre-prepare message, verify it is therein
After block, broadcast prepare message (includes out signature of the block people to block, and the node to the signature of signature).So
Enter the prepare stages afterwards.
3rd, the prepare stages.After being collected into the prepare message for certain block that more than 2/3 node sends, extensively
Broadcast commit message (including out signature of the block people to block, and the node to the signature of signature).And enter commit ranks
Section.
4th, the commit stages.After being collected into the commit message for certain block that more than 2/3 node sends, by this
Block adds block chain, into next height.
5th, there is any problem in the three above stage, including wait time-out, and signature verification is unsuccessfully etc..Continue to perform
Above-mentioned flow, only votes to NULL.If final more than 2/3 node is all voted to NULL, into next round.
If the 6, receiving the message more than present level or current round, all it is stored in message logging.If collected
To the message in certain stage of the present level future round of more than 2/3 node, then leap to stage of the round after
The message to be received such as continuous.
If the 7th, period be synchronized new block, newest height is directly entered, since round 0.
Based on above-mentioned technical proposal, alliance's chain common recognition system that the embodiment of the present invention is carried, number of the system to node of knowing together
Amount and book keeping operation order are known together, and can dynamically adjust book keeping operation order when node of knowing together changes, and realize the height of system flexibly

(outside account address), and the common recognition node (for example, at least 3 common recognition nodes) of predetermined quantity is specified, the present embodiment is not to pre-
The numerical value of fixed number amount is defined.
After the completion of initialization, after alliance's chain normally starts, contract can be written in wound generation block.Alliance's chain once run by
Wound generation block content cannot be changed, management threshold person address cannot also change, so needing properly to preserve very much management threshold person
Private key.
Based on above-described embodiment, in order to improve the operating efficiency of keeper, mitigate the task amount of management threshold person, common recognition section
Point management agreement module can also include：
Keeper's white list maintenance unit, the keeper's modification operation for being sent according to management threshold person updates keeper
White list.
Specifically, alliance's chain network is when creating, an account address incoming first, as the management threshold of the system
Member, the management threshold person can modify to keeper's white list.Account only in keeper's white list can just be entered
The additions and deletions operation of row common recognition node.The present embodiment is not defined to this.For example after the management threshold person can add more
Many keepers, but keeper can not be deleted.Common recognition node administration contract module maintains common recognition node white list and keeper
White list.
Based on above-mentioned any embodiment, the system can also carry out the management of network legal power, because publicly-owned chain does not have node
Mechanism of permitting the entrance, any node can from public network synchronous total data, can also be signed after certain book keeping operation power is obtained
Name goes out block.In the present embodiment network trading is by common recognition node sequencing and packs blocking, then broadcast to other nodes of network, collect
It is to be confirmed to be legal block to certain poll, read-only (common), although node does not go out block, it can be synchronized to connection
The all of initial data of alliance's chain, so common recognition and read-only node are required for strict access to manage.The system i.e. in the present embodiment
Can also include：
Synchronization node white list generation module, for generating and issue it is same with network connection and data syn-chronization authority
