Account and the asset class generate asset identification；The asset identification create-rule is for predetermined asset account and predetermined money
Produce what type was stated in advance in the intelligent contract；
Step S130: according to asset identification and assets number relevant information of the asset identification in the intelligent contract
One-to-one relationship in search corresponding assets number relevant information；Asset identification in the one-to-one relationship is basis
What the asset identification create-rule generated；
Step S140: the assets number relevant information found is performed corresponding processing according to management instruction.
Above-mentioned steps S110~step S140 is the management that the block chain assets of user how are realized from the description of the block end of the chain.
The block chain assets management method can be realized by equipment that block chain is based on, such as server, personal computer etc..
It can be communicated based on existing various communication protocols between block chain equipment and user equipment.
In above-mentioned steps S110, asset management request can be sent to block chain by user equipment by user and set
It is standby, for example, corresponding asset management request can be sent when user needs to carry out transaction in assets, queries the balance.The Assets Reorganization Taking
Reason request may include asset account and management instruction, or include asset account, asset class and management instruction.Wherein, should
Asset account can refer to the block chain account address of user, for distinguishing different users.User can be personal or mechanism,
For example, bank, electric business etc..The asset class is used to distinguish the type of different assets, for example, gold coin, stock etc..The management refers to
The content being managed for describing user to block chain digital asset is enabled, for example, producing the assets of certain number, queries asset
Remaining sum, inquiry Transaction Details etc..
In above-mentioned steps S120, intelligent contract, which may include, meets the various rules for calculating scene.The asset identification is raw
It needs to can be used for calculating generation asset identification according to it according to requiring to be pre-designed at rule.The asset identification can be used in
The ownership of identification asset, such as identify assets which user possesses or which user possesses which kind of assets.The asset identification
Create-rule is for designed by predetermined asset account and predetermined asset class.Money can be set in the asset identification create-rule
It produces account and asset class may be to user as it can be seen that only asset account may be to user as it can be seen that asset account
It can not be visible to user with asset class.Asset account may be in the visible situation of user, can be according only to the money
It produces account and generates asset identification, for searching the Asset List of the asset account.Asset account and asset class can not be right
In the visible situation of user, it is only capable of generating asset identification according to the asset account and the asset class, it is unique right to search
The assets number relevant information answered.
In above-mentioned steps S130, the one-to-one relationship of asset identification and assets number relevant information can pass through list

The asset class is bound, and using binding result as asset identification.It, can be by the assets in more specific embodiment
Account is as prefix, by the asset class after the asset account, forms the asset account and the assets
The binding result of type.
In the present embodiment, asset identification create-rule refers to, substantially directly according to the binding of asset account and asset class
As a result asset identification is obtained.In the case, it is had recorded in asset identification and the one-to-one relationship of assets number relevant information
It, can be by the binding result about asset account and asset class about the information of asset account and the binding result of asset class
Information as index, corresponding assets number relevant information is searched in the one-to-one relationship.Due to about asset account
Information be recorded in above-mentioned one-to-one relationship, so, in other embodiments, can be by the information about asset account
As prefix index, the assets number that the corresponding various asset class of the asset account are searched in the one-to-one relationship is related
Information, for example, the Asset List of user.
In this second embodiment, in above-mentioned steps S120, according to the asset identification create-rule in intelligent contract, according to
The asset account and the asset class generate the specific embodiment of asset identification, it may include: by the asset account and
The asset class is bound, and generates the first unique string by carrying out encryption to binding result, as asset identification.
It, can be using the asset account as prefix, by the asset class immediately the asset account in more specific embodiment
Later, the binding result of the asset account and the asset class is formed.Then encryption is carried out to binding result and generates first
Unique string.The algorithm of encryption for example can be symmetric encipherment algorithm, Hash Encryption Algorithm etc..Utilizing symmetric encipherment algorithm

The binding result of account and the asset class.
In the present embodiment, asset identification create-rule refers to, according to pair of asset account and the binding result of asset class
Encrypted result is claimed to obtain asset identification.In the case, in the one-to-one relationship of asset identification and assets number relevant information
The information about encrypted result is only had recorded, without recording the information about asset account and asset class, so intelligence is closed
User in about can not be obtained according to asset identification in the case where cannot get key active user about asset account and money
Produce the information of type.So this kind of asset identification create-rule can play the purpose of secret protection, but can not be by that will close
The corresponding all assets kinds of active user are searched in above-mentioned one-to-one relationship as prefix index in the information of asset account
The assets number relevant information of class.In the embodiment, key when symmetric cryptography can only be issued to corresponding user, only useful
Family oneself can obtain the information of its asset account and asset class.Alternatively, the key of symmetric cryptography can only be issued to intelligence
The manager of contract, the manager of intelligent contract can carry out unified decryption, in the case, intelligent contract to the information of lookup
Internal user can access the information of asset account and asset class, but the user outside intelligent contract is unable to get intelligence
The information of asset account and asset class inside contract, in this way, which this kind of asset identification create-rule can both play one
Fixed privacy effect, and can know together in order to the information of intelligent contract internal user.
Fig. 2 is that the method flow for generating asset identification according to asset account and asset class of one embodiment of the invention is illustrated
Figure.As shown in Fig. 2, in the third embodiment, in above-mentioned steps S120, generating rule according to the asset identification in intelligent contract
Then, the method for asset identification being generated according to the asset account and the asset class, it may include:
Step S121: being bound and encrypted with the asset class to the partial character of the asset account, generates the
Two unique strings, with the corresponding relationship of asset account described in unique identification and the asset class；
Step S122: the asset account and second unique string are bound, and using binding result as
Asset identification.
In above-mentioned steps S121, for example, can by first four of the asset account and it is rear four with the asset class
It is bound.The partial character of the asset account should be able to be used to distinguish the different asset accounts in the intelligence contract.
In the present embodiment, asset identification create-rule refers to, according to tying up for the partial character of asset account and asset class
The fixed and result of symmetric cryptography and the binding result of asset account obtain asset identification.In the case, asset identification and assets
The encryption of the binding result about asset account and asset class is not only had recorded in the one-to-one relationship of number relevant information
As a result information, is also recorded the information about asset account, but without record the partial character about the asset account with
The information of the binding result of the asset class.According to the encrypted result about asset account and the binding result of asset class
Information is capable of corresponding relationship (but the partial character of the asset account and the assets of queries asset account and asset class
The binding result of type can not be seen by the user), it is thus possible to it is closed according to asset account and asset class in above-mentioned one-to-one correspondence
The assets number relevant information for which kind of asset class which user possesses is found in system.In addition, according to about asset account
Information, can be found in above-mentioned one-to-one relationship the corresponding all asset class of user assets number correlation letter
Breath, for example, the Asset List of user.
In the fourth embodiment, in above-mentioned steps S120, according to the asset identification create-rule in intelligent contract, according to
The asset account generates the specific embodiment of asset identification can include: using the asset account as asset identification.Herein
In the case of, if having recorded the information about asset account in the one-to-one relationship of asset identification and assets number relevant information
(the case where to be encrypted to asset account), can be inquired according to the asset identification asset identification in the one-to-one relationship about
The information of asset account part, such as the prefix index generated according to asset account, each money that available user is possessed
The assets number relevant information of type is produced, such as obtains the Asset List of user.It generates and does not include asset class in asset identification,
And asset identification create-rule is for predetermined asset account and predetermined asset class, at this point it is possible to which the asset identification is raw
It is set as empty at the position for corresponding to asset class in rule.
In some embodiments, in the case where the asset identification is generated according to the asset account, above-mentioned steps
S130, according to the asset identification in asset identification money corresponding with lookup in the one-to-one relationship of assets number relevant information

In the case where number of deals, the assets number relevant information found may include TSID, can be in block chain according to TSID
Retrieve required Transaction Information.
Illustrate implementation of the invention with the specific embodiment of a transaction in assets below.
Fig. 3 is the interaction schematic diagram in the block chain asset management of one embodiment of the invention.Assuming that user 1 needs assets
The asset class B that assets number a in type A transfers accounts to user 2.Referring to Fig. 3, user 1 can be by user equipment 1 by user
1 account address address1, asset class A, the account address address2 of user 2, assets number a, asset class B, turn
Account instruction etc. is input to the service of intelligent contract of the invention.
Tens of thousands of a block chain digital assets are defined in intelligent bond service of the invention.Intelligent contract records block chain
The binding relationship of account address, the end-state of block chain contract assets and account and asset class symbol, in turn
Corresponding amount of assets, for distinguishing some account, possessing certain digital asset, how many amount.The intelligence contract is according to address
It is identification information with symbol, generates assets unique identification using sha256 encryption or symmetric cryptography (AES).Use unique identification
As key value, remaining sum amount, the Value=amount of value record identification are stored in KV in a manner of key=value
In database.Thus, so that it may by an intelligent contract administration and record several hundred thousands of kinds of digital assets.Wherein key
It can be arranged by following three kinds of modes.
Mode one: Key=address_symbol is carried out by account address address, assets symbol symbol in this way
Binding is used as unique index, queries asset balance information；It can be simultaneously prefix index by address, inquire address pairs
All assets remaining sum lists answered, but this mode can be in contract storage inside account address and assets symbol, concealment is not
By force.
Mode two: key=AES (address_symbol) passes through AES using the character string after address+symbol
The mode of encryption generates a unique string as index value, can play the purpose of secret protection in this way, but cannot lead to
Address is crossed as prefix, inquires the corresponding all Asset Lists of account.
Mode three: asset addresses: Address+base64 (AES (preceding the four of four+symbol+address after address
Position)), it by the list of asset addresses queries asset and can be parsed according to account address and assets symbol inquiry assets remaining sum
Assets remaining sum out can also pass through asset addresses queries asset remaining sum.
Assets mark can be generated according to one of aforesaid way according to the account address address1 of user 1 and asset class A
Know address1_A, according to asset identification address1_A as index value, inquires KV database, account address can be found
The corresponding assets remaining sum x of address1 and asset class A；According to the account address address2 of user 2 and asset class B foundation
Asset identification address2_B can be generated in one of aforesaid way, according to asset identification address2_B as index value, inquiry
KV database can find the corresponding assets remaining sum y of account address address2 and asset class B.
If, can be only in a contract, and in the identical situation of the trading rules of asset class A and asset class B
Realize the exchange that two kinds of assets of A and B are carried out between user 1 and user 2 by x-a, y+a, the transaction of block chain realize across
Assets circulation.If needing the external common recognition of contract in different contracts.It is then possible to by transaction in assets as a result, including account
Family address address1 and asset class A corresponding new assets remaining sum x ', account address address2 and asset class B is corresponding
The information such as new assets remaining sum y ' be sent in block chain, record gets up.
It can be seen that user only with installation one service, so that it may trade hundreds of, thousands of kinds of digital assets, reduce dimension
Cost is protected, trading efficiency is improved.Generally contract code is all disclosed, some have programming basis, some do not have, many leaky
Contract assets, it is so huge wind for the user of no technical capability that publisher, which deliberately increases the loophole for being conducive to oneself,
Danger, user can not often identify, if multiple assets contract follows the assets contract template of official, be sent out based on a template
Row has thus prevented problems to a certain extent, reduces user to the assessed cost of contract, new user can pass through group
Realization knows identification contract technical risk, improves identification, can also reduce trust cost with this.Such contract can be by authoritative machine
Structure is runed and is safeguarded, with a high credibility, highly-safe.
