Destination node in above-described embodiment refers to the node in above-mentioned block chain with data offers permission, number of targets
According to referring to wait deposit the data for demonstrate,proving the block body into block chain.The candidate block that the node is proposed includes block head and block body.Area
Build usually encapsulates the block of the current version number of the block catenary system, the address of previous block or data summarization, this block
Data summarization (the Merkel Root such as to trade) information of body, is not construed as limiting in the present specification.In reality provided by the invention
It applies in example, the block head of candidate block is also packaged with the metadata of target data, to describe the target data of above-mentioned card to be deposited.
Metadata mainly describes data attribute (property) for the data (data about data) for describing data
Information, for support such as indicate storage location, historical data, resource lookup, file record function.It is encapsulated in block head
The metadata of target data, and data in block head such as block abstract, metadata etc. can be used as retrieval object, can be used
Easily know that the target data content of card, the retrieval convenient for target data content, lookup are included or deposited to the block in family.And
And the user of some block catenary systems, it is limited to itself permission or hardware configuration, is selected in locally-installed light joint form
Client, which usually only saves the block head data of the block of block chain whithin a period of time, for previous
Block head is only packaged with the mathematics abstract of included transaction in the block abstract of father's block of this block and the block body of this block
The case where, light node users can not know it in the overview of the target data of the deposited card of block chain locally saved；This explanation
The metadata information encapsulation of target data is stored in the embodiment of block head provided by book embodiment, it can be more convenient
Access and retrieval of the above-mentioned light node users to block chain institute storing data.
In above-described embodiment that this specification provides, it should be deposited in the block body for the candidate block that the node of block chain is proposed
The content of the target data is demonstrate,proved, those skilled in the art is apparent from, and the content of above-mentioned target data is in the form of " transaction "
It is stored in block body.Transaction (transfer) described in this specification refers to that user passes through the client of block chain
Creation, and a data for needing finally to be distributed in the distributed data base of block chain.Wherein, the transaction in block chain, is deposited
In point of the transaction of the transaction and broad sense of narrow sense.The transaction of narrow sense refers to the value Transfer that user issues to block chain；
For example, transaction can be one that user initiates in block chain and transfer accounts in traditional bit coin block chain network.And broad sense
Transaction refer to a business datum being intended to business that user issues to block chain；For example, operator can be based on real
The business demand on border builds alliance's chain, rely on alliance's chain dispose it is some unrelated with value Transfer other types of online
Business (for example, business of renting a house, vehicle scheduling business, settlement of insurance claim business, credit services, medical services etc.), and this kind of
In alliance's chain, transaction can be the service message or service request with business intention that user issues in alliance's chain.
The particular content of the transaction is not limited in the present specification, the target data of any form or content can be used as transaction and deposit card
In block chain described in this specification.
Step 104, it initiates to handle the common recognition of the candidate block.
After each node device of above-mentioned block chain receives candidate block, which should be initiated to candidate block
Common recognition processing.This specification does not limit above-mentioned common recognition and handles followed common recognition mechanism criterion, any to be able to achieve this explanation
The common recognition mechanism or common recognition algorithm of technical solution described in the embodiment that book provides, in the range of this specification is protected.
Hereinafter, this specification by taking PBFT knows together algorithm as an example, sketches the above-mentioned common recognition treatment process to candidate block.Alliance
Chain usually selects PBFT as the common recognition mechanism of itself, to increase the handling capacity of network.
When realizing, before each round common recognition of block chain starts, can be selected in each node device in block chain
Enumerate a host node device (for example, each round common recognition all re-elects out a host node device, other node devices be used as from
Node device), it knows together from host node device to transaction is initiated, and be responsible for the transaction data (or target data) passed through based on common recognition
For the newest block of block chain creation.
For example, being based on Pbft algorithm, before alliance's chain each round common recognition starts, it can be based on formula below, for this
Wheel formula calculates a host node device:
P=v mod R
Wherein, P indicates the master node number of calculated epicycle common recognition；V indicates the current view number of alliance's chain；View
Number is usually the integer of a serial number, indicates that alliance's chain is successfully completed the wheel number of common recognition；For example, successfully completing
One wheel common recognition can be by view number certainly after the host node device elected is successfully written a new block to alliance's chain
It is dynamic to add 1.R indicates the total quantity of the node device in alliance's chain.
Each node device can execute the above calculating respectively, and by the number of calculated master node number and this equipment
It is matched, to determine whether this equipment is elected as host node device.
On the one hand, if a node device determines that this equipment is not elected as host node device, can will receive by
Each node device of the transaction that client is submitted into alliance's chain carries out broadcast transmission.
On the other hand, if a node device determines that this equipment is elected as host node device, each use can be collected
The transaction of family client broadcast transmission within the common recognition period of epicycle, and based on the transaction being collected into, to create transaction List Table.
At this point, the transaction List Table of creation is the transaction data for carrying out common recognition processing that host node device is proposed.
Pbft algorithm generally can be divided into pre-preparation (pre-prepare), prepare (prepare) and confirmation (commit) etc.
Three phases.
Host node device carries transaction List Table in Pre-Prepare message, and then the Pre-Prepare message exists
Broadcast transmission is carried out in each node device in alliance's chain, complete transaction List Table is propagated in alliance's chain and needs to participate in hand over
The slave node device easily known together.
The slave node device for receiving above-mentioned Pre-Prepare message, can follow the regulation of pbft algorithm first, to receiving
Pre-Prepare message verified, to determine whether to receive the Pre-Prepare message that receives.
Wherein, in the present specification, the Pre-Prepare message received is verified, as to the Pre- received
The process that the content carried in Prepare message is verified；
Such as, it then follows the regulation of pbft algorithm can carry transaction data to be known together in Pre-Prepare message
The information such as (being target data in this specification), view number v, digital signature.Correspondingly, in the present specification, to Pre-
When Prepare message is verified, verification process below can be specifically executed:
1) it verifies view number V and whether the view number of local record is consistent；
2) digital signature in Pre-Prepare message is verified；
3) validation verification is carried out to the target data carried in Pre-Prepare message；
The above-mentioned validation verification to target data, it can be understood as it is each from node device to the accurate of target data
Property, validity etc. verified, before target data is formally indexed to above-mentioned block chain, to obtain portion by area
(in PBFT algorithm, the approval of at least 2F+1 member, F is visiing for the block catenary system for the approval of most members of block chain
Account for the fault-tolerant number in front yard) target data.
When the node device for receiving above-mentioned Pre-Prepare message, after executing verification process out listed above, if
It is verified, indicates that the node device receives above-mentioned Pre-Prepare message (approving to above-mentioned target data), at this time the node
Equipment can enter the Prepare stage of pbft agreement, other each node device broadcast transmissions one into alliance's chain with
In the Prepare message confirmed to above-mentioned Pre-Prepare message；Wherein, the content carried in above-mentioned Prepare message
Format can be consistent with above-mentioned Pre-Prepare message.Each node device also can receive by other respectively from node device
The Prepare message of broadcast transmission is verified to Prepare message is received, to determine whether that the Prepare for receiving to receive disappears
Breath.Wherein, it to the detailed process for receiving Prepare message and being verified, can be verified with reference pair Pre-Prepare message
Detailed process, no longer repeated in the present specification.
Node device in alliance's chain other each node device broadcast transmission commit message into alliance's chain it
Afterwards, it also can receive by the commit Messages Message of other each node device broadcast transmissions, test commit message is received
Card, to determine whether the commit message for receiving to receive.
Wherein, the content format carried in above-mentioned commit message, can disappear with Pre-Prepare message and Prepare
Breath is consistent.It wherein, can be with reference pair Pre-Prepare message to the detailed process for receiving commit message and being verified
The detailed process verified, is no longer repeated in the present specification.
If the verification passes, indicate that the node device receives the commit message received, which can also be into one
Step determines the quantity of the commit message by other each node device broadcast transmissions received, if reach 2F+1 (including
Including the commit message of own broadcast), F is the Byzantine failure tolerance number of the block catenary system.
By above common recognition process, all node devices of block chain obtain portion and approve through most of node devices
Target data, avoid user in different network platform servers to the situation of the target data of same target description not
It uses up identical and which does not know for true defect.
Step 106, the common recognition passed through is handled as a result, using the candidate block as most in response to the candidate block common recognition
New block is stored to the distributed data base of the block chain, to complete to deposit card for the data of the target data.
The mechanism of common recognition treatment mechanism and the distributed storage backup of block chain ensures that any user is difficult to the approval
Target data afterwards is distorted, and deposits card to obtain authentic and valid data for user and provide.For example, by using Pow common recognition
Block chain, the attack at least needing the whole network 51% to calculate power is possible to distort data with existing, therefore block catenary system has other
Centralization Database Systems it is incomparable guarantee data security, the characteristic that attack protection is distorted.It is above-mentioned using PBFT common recognition
Block chain has reached full chain to the strongly consistent of transaction data, therefore keep away by host node and the confirmation from node to transaction data
Exempt from user to be not quite similar to the situation of the target data description of same target in different network platform servers and do not know
Which is true defect.By the way that the data (target data) of card to be deposited are stored on block chain, this is reached by common recognition
The approval of all members of block chain or most of member to data, the true and false difficulty of data that can be effectively prevent on internet above-mentioned
The problem of distinguishing
In the another embodiment shown, the metadata information for the target data included packaged by above-mentioned block head includes mesh
The data summarization for marking the unique identification of data or the unique identification of target data, is more convenient for block chain client user
Retrieval to the included information of block chain.
It is below for house property information deposits the business scenario of card, to discuss the embodiment of the technical program by block chain.
For the same feature of same house property, such as area, house type, quotation, should guarantee uniquely to describe in a network, it is any to prevent
User occurs the difference description to the same feature of same house property information when inquiring house property information, hard to distinguish between the true and false.It is handed over to reduce
Easy or target data acknowledging time improves transaction handling capacity, meets the needs of to safety and performance, usually selects alliance's chain frame
Structure constructs the block chain.In the business scenario of above-mentioned dealing house property, the letter such as house property medium company, house transaction supervisory organ
With higher mechanism, it can be used as allied member's node of alliance's chain, participate in the book keeping operation of block.For example, the common recognition of alliance's chain
Journey can refer to above-mentioned according to the progress of the common recognition process of PBFT algorithm.Alliance's chain can be determined according to application scenarios to the public's
Degree of opening gives the permission for accessing alliance's chain on limits focal pointe, and accessible node can be also divided into
General node and light node, light node does not have the permission for participating in the book keeping operation of alliance's chain generally, and generally preserves alliance's chain and exist
The block head data of block in one period, to save memory space.
PBFT algorithm as alliance's chain provided by this specification common recognition algorithm a kind of preferred embodiment, be by
It is high-efficient in being known together using this kind of algorithm, can meet the needs of high frequency trading volume, such as each house property medium in the present embodiment
Company frequently generates house property information (transaction)；And the time delay of common recognition is very low, basically reaches the requirement handled in real time, it can quickly in real time
Above-mentioned house property data information is included in the newborn block of block chain in ground；Moreover, by trusted node such as house property in alliance's chain network
Accounting nodes of the regulatory agency of transaction as pre-selection, have taken into account safety and stability；In addition, will not be disappeared using PBFT algorithm
It consumes excessive computer and calculates power resource, be also not necessarily required to that token circulates, therefore there is good workability.
Pass through the common recognition mechanism of block chain, it is ensured that for the same feature (offer in such as house of same house property information
Breath), it is only deposited on block chain and demonstrate,proves a kind of description after member node is known together.Under above-mentioned business scenario, alliance's chain it is every
The above-mentioned metamessage included in the block head of a block can be the address information of house property or the digital digest of house property address as breathed out
Uncommon value can uniquely determine house property at one by the information due to the unique identification that the address information of house property is a house property.User
The address information of the house property or the cryptographic Hash of house property address are retrieved in the block chain database comprising block head by client
Afterwards, one or more block corresponding with the house property can be got, then to inquiry room in the block body of the block inquired
The specifying information of production, such as house address, house property people's information, house type, area, price etc..
It is worth noting that, to deposit application of the card method in different business scene convenient for the data that this specification provides,
The format that the target data information or Transaction Information for including in block body can be instantiated using foundation business scenario, for example,
In the block body of the block chain of the above-mentioned business scenario for depositing card for house property information, as shown in Fig. 2, can be installed with for the interior of house property
Set the instantiation content template including address, house type, area, house property people, quotation information；It further, can also be room
The instantiation of the address setting in room such as " city xx of the xx province area the xx street the xx room xx " format describes, for house house type setting such as the " room xx xx
Room xx defends xx balcony " etc. formats instantiation description, etc., consequently facilitating house property medium mechanism propose about a target house property
Certain important informations will not be omitted when the candidate block of information, so that all information about the target house property information are protected
There are in the same block, the access of more convenient user.
It is proposed in above embodiment, passes through the common recognition mechanism of block chain, it is ensured that for the same of same house property information
Feature (quotation information in such as house), only deposits on block chain and demonstrate,proves a kind of description after member node is known together, but also not
Exclude it is extremely individual in the case where, caused by the specific common recognition mechanism taken the block chain, different house property mediums
The different descriptions of the same feature of same house property information are included to above-mentioned block chain, i.e., bifurcated occurs in above-mentioned block chain:
There is a certain target block on the block chain and is connected with sub-block more than one.In this case, this specification
One embodiment provide following scheme to solve above-mentioned bifurcation problem: when on the block chain either objective block connect
Multiple sub-blocks are connected to, the quantity of the sub-block where counting the multiple sub-block on branch；By the quantity of the sub-block
