The method of block chain technology realizes the digital asset circulation method of decentralization, realizes that the distribution of digital asset, transfer are even destroyed
Fast and effective progress, eliminate the reliance on third-party transfer mechanism;A kind of digital asset circulation method based on block chain
Including:
Step 110, certification assets circulation initiator's user identity;
There are many modes of the verification user identity, by taking the present embodiment as an example, including but not limited to following method:
Method 1:The identity information of total user is summarised in background data base, is getting information input by user
Afterwards, itself and existing information in database are compared, compares the user passed through and complete certification, and corresponding user can be called
Information.In this case, arbitrary validated user can use and log in the corresponding system of this method;
Method 2:The identity information of specific user is write extremely in systems in the form of hardware or software, in this case,
Only some validated user is allowed to use and logs in the corresponding system of this method;
Method 3:The identity information of user is stored on the move medias such as magnetic card, by the letter for comparing card user's input
The information preserved on breath and move media, carrys out certification user identity.Here, the identity information of user can be " user name+mouth
Enable ", can also be the multiple types such as fingerprint, face.
Further, the corresponding one or more public private key pairs of the identity information of each user.User is passing through body
After part verification, so that it may to use corresponding private key to sign and issue assets negotiation.Optionally, user can also voluntarily create, update
Public private key pair, still, each public private key pair that user creates always are bound with the identity information of user.Therefore, it is carried by user
The public key of confession can recognize that the specific identity of user.
The user can be issue digital asset businessman, can also be customer, can be commodity seller, can also
It is seller, can be supervision department can also be any third party, the method is based on block chain technology so that is using this hair
User either seller or buyer in bright, it is any to there is demand to carry out digital asset all in the equality position of decentralization
Circulation with can realize through the invention per family.
Step 120, receive certification by assets circulate initiator user issue user instruction;
Because user identity is different, permission is different, to ensure the order of entire block chain network, the user logged in need to be first confirmed
Whether the permission of independently transmitted user instruction is had;
Further, as shown in Fig. 2, the method further includes:
Step 121, according to certification by user identity, judge whether the initiator user needs N number of third party to recognize
User instruction can be just issued after card;
If not needing, which has and can continue to issue user by verification with the permission of independently transmitted user instruction
Instruction;
If desired, step 122, determine the N number of third party for needing certification, referred to according to user identity and the quasi- user issued
Construction signature request is enabled, and the signature request is sent to N number of third party and is authenticated;
N number of third party can be all the user for logging in the system of the present invention;Pass through same block chain network and the N
Each third party communicates;
Step 123, receive it is described it is N number of it is third-party each authentication result and its corresponding third party's signing messages;
And third party's signing messages is attached in the user instruction;
Cannot independently transmitted user instruction user after having signing messages third-party enough, that is, obtain N
After a third party allows, you can issue user instruction;
Further, in many cases, as the N number of third-party signing messages required that gather together enough may spend the time
It is longer, and multiple third-party signing messages i.e. provable its that corresponding user may need to be less than N is sent out the user sent and is referred to
The reasonability of order, the method further include:
The initiator user can issue user instruction after needing M certification in N number of third party;It is N number of when receiving
After M authentication result and its corresponding M third party signing messages in third party, i.e., by the M third party signing messages
It is attached in the user instruction;And circulation record is sent in block chain network, wherein 1≤M≤N, and M is whole
Number;
The pre-set N number of third party of user of the permission without independently transmitted user instruction, and towards N number of third
Side sends signature request simultaneously, can issue user instruction after receiving M feedback therein, improve the speed of operation in this way
Degree, also avoids that there are the authority requests of bad point Third Party Effect user.
Step 130, circulation record is generated according to user instruction, the circulation record includes assets circulation initiator user
Signature;
Further, because digital asset stream is logical along with risk, therefore after generating circulation record, to the circulation record
Risk class is assessed:
As shown in figure 3, the method further includes:
Step 131, it is determined to block chain network according to the user instruction content and sends the circulation that the user instruction generates
The risk class of record;
The risk class integrates multiple risk factors according to preset rules and obtains;The risk factors include initiator
The credit grade of user, which is less than predetermined threshold value, the credit grade of recipient user is less than predetermined threshold value, is related to digital asset is higher than
Predetermined threshold value, digital asset type are that preset high risk type and initiator or recipient IP are abnormal;
Step 132, judge risk class whether higher than default risk threshold value;
When the risk class is higher than default risk threshold value, pause digital asset circulation, and carried out to initiator user
Indicating alarm;
When the risk class is less than default risk threshold value, continue circulation record being sent to block chain network;
Further, to ensure risk averse, the digital asset that default risk threshold value is less than for risk class circulates, root
According to the risk class of the circulation record, the number of nodes reached common understanding to circulation record in the block chain network is adjusted
It is whole;I.e. risk class is higher, needs the number of nodes reached common understanding more;By taking the present embodiment as an example, when risk class is at certain
X grade is often higher by a base level, the number of nodes that need to reach common understanding increases Y by preset rules in present node quantity
It is a;
Further, supervision confirmation is carried out to circulation record:
According to preset regulatory rule to the circulation record carry out supervision confirmation, if the circulation record do not meet it is default
Regulatory rule, then it includes the detailed assets circulation information of assets circulation purpose to need to ask initiator's user feedback, and will
The assets circulation information and corresponding circulation record are sent to third-party monitoring department and are confirmed;
If being identified through, continue circulation record being sent to block chain network;
If confirmation does not pass through, the circulation of this assets is terminated.
Step 140, circulation record is sent to block chain network;
Node in block chain network reaches common understanding to circulation record;It is any because of the characteristic of block chain network technology
Use in block chain network can inquire block and confirm whether circulation record reaches common understanding per family;
Step 150, after detecting that circulation record is reached common understanding in block chain network, update assets transfer initiator uses
The account balance at family.
Further, the user instruction includes but not limited to assets distribution instruction, assets transfer instruction and assets pin
Ruin instruction;The present embodiment is illustrated by taking this three kinds instructions as an example;
The assets distribution instruction needs user itself to have the permission of distribution digital asset, and the user instruction is assets hair
When row instruction, before circulation record is sent to block chain network, the method further includes:
Construction signature request is recorded according to according to the circulation;The signature request includes the detailed of assets distribution circulation record
Thin information;
The signature request is sent to third party to assess, judges the compliance of the assets distribution;The conjunction rule
The judgement of property includes whether the initiator user issue the qualification of digital asset, the account assets of the initiator user
Whether the amount of assets in distribution circulation record and the exchange rate in circulation record enough be correct;
Herein, the third party can be relevant government department, legal agency, rating organization etc.;Likewise, above-mentioned
Tripartite can complete compliance by using the corresponding method and system of the present invention and judge;
For example, the third-party institution assert that the initiator user has the qualification of distribution digital asset and the user is qualified
The exchange rate issued 3000 pieces of digital cash, and confirm digital cash to RMB is 10:1, then judge that compliance is errorless, and by phase
It closes information and feeds back to initiator user;
If judging, the compliance of the assets distribution is errorless, can continue to execute step 140 and the circulation is recorded transmission
Into block chain network;
If judging the compliance of assets distribution there are problem, suspend digital asset circulation, and to initiator user
Carry out indicating alarm;
Further, after the account balance that assets circulation initiator user is updated described in step 150, the method is also wrapped
It includes:
Assets circulation initiator user receive the assets from purchaser user transfer accounts, the assets transfer accounts including currency with
And digital asset is transferred accounts;It is transferred accounts according to the assets and the exchange rate calculates the digital asset quantity that purchaser user buys;
According to the digital asset quantity establishment transaction circulation record of purchaser user's purchase, the transaction is circulated and records hair
It send to block chain network;
After detecting that circulation record is reached common understanding in block chain network, the account of update assets circulation initiator user
Remaining sum.
When the user instruction is that assets transfer instructs, the circulation record of the generation further includes transaction acceptance side user
The type and the amount of money of digital asset are shifted in account address, initiator user;
It is different from assets distribution, carry out assets transfer i.e. information of clear recipient user when assigning user instruction;
After the recipient user detects that circulation record is reached common understanding in block chain network, more than the account of update recipient user
Volume;
In system level, initiator user and recipient user may use same block chain interactive module, it is also possible to
Use two different block chain interactive modules;If using same block chain interactive module, flowed then being sent in initiator user
Logical when being recorded in block chain network, the block chain interactive module for being equivalent to initiator user and recipient user all starts in area
Detect whether that node is reached common understanding (because being same) in block chain network;When using different block chain interactive modules,
The recipient user detects that the mode of circulation record includes copying for the circulation record sent according to the initiator user of reception
Shellfish information is detected in block chain network and reads in real time newest block in block chain network and is related to itself to obtain
Transaction Information;
Further, the digital asset type that digital asset type needed for the recipient is shifted with described sender not phase
Meanwhile the circulation record of the generation further includes the digital asset type of digital asset type needed for recipient and sender's transfer
Between the exchange rate and according to the exchange rate calculate recipient receive the corresponding amount of money of digital asset type;
Further, the acquisition modes of the exchange rate include accessing trusted third party to obtain the reality between different digital assets
When the exchange rate and according to the exchange rate between the corresponding digital asset of setting of making an appointment of a variety of digital asset publishers;The basis is more
The exchange rate between the corresponding digital asset of setting of making an appointment of kind digital asset publisher can irregularly be adjusted according to market trend situation
Whole, the adjustment mode includes being replaced and by multiple digital asset publishers according to the real-time exchange rate obtained from third party
It is manually adjusted after negotiation;
Further, the exchange rate is obtained by multiple exchange rate acquisition modes so that the real-time exchange rate between every two kinds of digital assets
There are it is multiple when, between the multiple real-time exchange rate select an optimal exchange rate;The selection mode includes according to preset rules
It automatically selects the optimal exchange rate and is presented to the user the multiple real-time exchange rate, and confirmed according to the selection result of user feedback
The optimal exchange rate;
It is small etc. that the preset rules such as exchange rate hopes that the big or exchange rate is hoped;
Further, when the user instruction is that assets destroy instruction, the circulation record of the generation further includes initiator
The private key of user, digital asset type to be destroyed and the amount of money;
A kind of digital asset circulation method based on block chain gives and realizes number money under decentralization thought
The method quickly to circulate is produced, the method needs not move through the complicated conversion of transfer mechanism or changer body etc., utilizes block chain
