Assets mandatory system 102, for the lower chain solicited message with assets application terminal system signature It is verified, after being verified, the lower chain solicited message with assets mandatory system signature is sent to assets trusteeship party. The verification process that assets mandatory system verifies the lower chain solicited message with assets application terminal system signature are as follows: assets Mandatory system obtains corresponding with assets account book address according to user's corresponding assets account book address from assets account book system Assets information on chain, and initial block message corresponding with the park assets classification of assets information on chain；Lower chain is used later Client public key in the letter of identity of solicited message verifies lower chain solicited message corresponding assets account book address, verifying After success, with judging the assets account book that index information corresponding assets account book address and real name account book record are registered to lower chain trustship Whether location is identical, if it is different, then authentication failed；If they are the same, then judge whether the lower chain amount of assets of lower chain assets information is less than The amount of assets of assets information on all chains corresponding equal to assets account book address, and lower chain assets information is stepped on to lower chain trustship Remember that the sum of corresponding efficient portfolio Board Lot of index information is more than or equal to the lower chain amount of assets, if it is not, then authentication failed； If so, judging the park assets classification of the park assets distribution request to lower chain original block block number and the support of lower chain assets information Whether pipe class of assets is identical, and the lower chain amount of assets of lower chain assets information is equal to the trustship for including to lower chain original block information The sum of efficient portfolio Board Lot in assets distribution of information, if so, being proved to be successful；Otherwise, authentication failed.
Assets trusteeship party 103, for testing the lower chain solicited message with assets mandatory system signature Card after being verified, park assets identical with the lower chain amount of assets is returned and are transferred the possession of to the user.Assets trusteeship party The verification process that lower chain solicited message with assets mandatory system signature is verified are as follows: assets trusteeship party verifies lower chain and asks The signature of the assets application terminal system in information and the signature of assets mandatory system are asked, after being verified, judges lower chain request Whether the letter of identity letter of identity corresponding with signature in the corresponding real name account book record of information is consistent, if unanimously, verifying Pass through；Otherwise it verifies and does not pass through.After being verified, assets trustship direction assets right registration system initiation handle subrogation to The operation that the corresponding user of user information is returned in lower chain solicited message, i.e., will be requested by assets right registration system with lower chain The identical park assets of the lower chain amount of assets of information, which are returned, to be transferred the possession of to corresponding user, and chain under assets is so far completed on chain.
Fig. 2 is that the system of chain carries out the main flow signal of chain under assets on chain under assets on chain in the embodiment of the present invention one Figure.As shown in Fig. 2, the system of chain carries out the main flow of chain under assets on chain, packet under assets on the chain of the embodiment of the present invention one Include following steps:
Step S201: user accesses the assets application terminal system of installation on the terminal device, according to what is pre-set It logs in after identification method submits identification information and logs in assets application terminal system.Assets application terminal system is mounted in terminal and sets Standby upper system software corresponding with assets account book system；User can be by accessing assets mandatory system, from assets trustship system It unites assets application terminal downloaded and installed system software.Terminal device can be with display screen and supported web page browsing Various electronic equipments, such as mobile phone, tablet computer, desktop computer etc..Wherein, the login identification method can be user name With the modes such as password identification, fingerprint recognition, recognition of face, corresponding identification information may is that username and password, or with this The identification code of the corresponding preset format of user name.The identification code of the preset format can be the password of character style, can also be with It is bio-identification code, such as the fingerprint of user, facial information, iris information.
Step S202: assets application terminal system determines that user is after being associated with the real name user of assets account book address, from The corresponding real name account book record of user is obtained in assets mandatory system.The corresponding real name account of user is stored in assets mandatory system This record.Assets mandatory system, which can be, holds in the palm the real name registration assets under chain by specified assets trusteeship party user The system that pipe registration management and the process that park assets are issued with digital asset on block chain carry out registration management, user It can be accessed by Web or other means to the assets mandatory system, the process for issuing digital asset includes assets under chain Chain process under assets in cochain process and chain.Wherein, assets cochain under chain is the real name assets by user under block chain After the trustship of assets trusteeship party, from assets mandatory system, number is provided on the assets account book system distribution chain based on block chain It produces；Chain under assets on chain, is that digital asset by user on block chain cancels, and by the corresponding chain subiculum of the digital asset Pipe assets, which are returned, to be transferred the possession of to user.User can access to the assets mandatory system by Web or other means.Wherein, Real name account book record includes: and the associated letter of identity of the identity information of user and associated with the identity information of user Assets account book address, the letter of identity includes: identity and the client public key of user.Letter of identity can be as information CA (Certification Authority, certificate authority) certificate that non-repudiation provides.
Client public key and private key for user are locally being generated using rivest, shamir, adelman by assets application terminal system.User Private key can be used for the bank card information to subscriber identity information, user, the bio-identification code information of user or the identity of user The data informations such as certificate are signed, can also be in subsequent transaction in assets or financing process for carrying out to digital assets information Signature, to confirm the ownership of transaction；Client public key can be used for by the private key for user carry out the data information signed into The corresponding verifying of row.
Step S203: lower chain operation entry corresponding with class of assets is passed through terminal device by assets application terminal system Show user.Digital asset is subjected to classification processing, the corresponding unique money of every class digital asset in advance in the embodiment of the present invention Produce classification number.Digital asset includes alienable digital asset and indivisible digital asset, and alienable digital asset is Finger can divide the park assets that original block includes under chain, such as stock, gold etc.；Indivisible digital asset refers to The park assets that original block includes cannot be divided under chain, such as house, historical relic, copyright, banking contract etc..When two parts When assets belong to one species alienable digital asset, operation can be carried out between this two parts of assets.Two parts indivisible It is also that cannot carry out operation between this two parts of assets, for example, digital asset house property even if digital asset belongs to one species A and digital asset house property B cannot carry out operation between this two parts of assets although belonging to house property class.Use class of assets Such assets can be specified and belong to alienable digital asset or indivisible digital asset, cleared convenient for lower chain.
Step S204: user by terminal device select to lower chain the corresponding lower chain operation entry of park assets classification, Selection and/or the lower chain amount of assets of input.User selects the corresponding lower chain operation entry of some class of assets, assets application terminal After confirmation user is real name user, the real name identity information of user is shown, user selects lower chain amount of assets, and confirmation carries out lower chain Operation.
Step S205: assets application terminal system is based on park assets classification and lower chain amount of assets generates lower chain request letter Lower chain solicited message with assets application terminal system signature is sent to assets mandatory system by breath.The lower chain request letter Breath refers to that user for the digital asset of oneself cochain, can initiate the request that chain is returned under assets.In optional embodiment In, the lower chain solicited message includes: returning user information and lower chain assets information etc..The return user information includes: use The identity at family and real name account book record etc., user herein refers to the user for having chain demand under assets.The lower chain assets Information can be the assets information that user requests lower chain, and in an alternate embodiment of the invention, the lower chain assets information includes: trustship money Produce classification, lower chain amount of assets, to lower chain trustship registration index information (information is stored in embodiment with tabular form) and to Lower chain original block block number etc..Generate the specific implementation of lower chain solicited message are as follows: record first according to real name account book, acquisition and real name Assets information on the corresponding chain in assets account book address of account book record, wherein assets information includes the assets on the chain Assets trustship registration index information (deposited with tabular form in embodiment by the information in the corresponding amount of assets in account book address and chain Storage)；Later using assets information on chain as assets information after current transaction, transaction previous existence is obtained by assets information after currently trading At the preamble assets information of assets information after current transaction；Using preamble assets information as assets information after current transaction, step by step Initial block message is dateed back, one group of initial block message is selected in initial block message, so that the initial block message selected is wrapped The sum of efficient portfolio Board Lot contained is less than or equal to the sum of corresponding amount of assets in assets account book address；It is initial by what is selected The sum of efficient portfolio Board Lot that block message is included is used as lower chain amount of assets, and the initial block message selected is corresponding Original block block number is used as to lower chain original block block number, by assets trustship registration index on the corresponding chain of initial block message selected Information, which is used as, registers index information to lower chain trustship, to be indexed based on the lower chain amount of assets, described register to lower chain trustship Information and described the lower chain solicited message is generated to lower chain original block block number.Efficient portfolio Board Lot is that assets issue unit Quantity subtracts the result that the asset units quantity being terminated obtains.
Biography can be used when selecting initial block message in a case where lower chain amount of assets is arbitrarily inputted for user The dynamic programming algorithm of system finds possibility identical with lower chain amount of assets and combines.For user according to certain held inquired The case where amount of assets of class assets selects several initial block messages, chain amount of assets lower with determination, can be to assets support on chain The efficient portfolio Board Lot of the corresponding all initial block messages of pipe registration index information is ranked up, according to ranking results recurrence The efficient portfolio Board Lot for lower chain amount of assets is selected and is worth, the efficient portfolio Board Lot selected is corresponding just Beginning block message is as the initial block message selected.Find out efficient portfolio Board Lot for recurrence herein and value is that lower chain provides Produce all possible combination of quantity.
Step S206: after assets mandatory system verifies the signature of lower chain solicited message, to lower chain solicited message, assets account book Assets information and initial block message are verified on the chain that system saves, and after being verified, will have the assets mandatory system The lower chain solicited message of signature is sent to assets trusteeship party.Assets account book system is the assets account book system based on block chain technology System can realize the operations such as verifying, inquiry, record by node of knowing together on chain thereon.The step is for requesting assets trusteeship party It handles park assets and returns transfer operation.It is to the verification process of assets information and initial block message on lower chain solicited message, chain Multiple-authentication, specific implementation are as follows:
Assets mandatory system sends inquiry request to assets account book system；
Assets account book system is recorded according to real name account book, and the assets account book address for searching real name account book record is corresponding all Assets information and the corresponding initial block message of the park assets classification, feed back to assets mandatory system for lookup result on chain；
Assets mandatory system verifies whether lower chain solicited message takes with the initial block message of assets account book system storage, storage The park assets of business system storage save information and are consistent, and specific verification process is as follows:
Real name account book in user information is returned using the client public key verifying in the letter of identity of lower chain solicited message to record Assets account book address, when being verified and the lower chain assets information corresponding assets account book address of lower chain solicited message and real name When the assets account book address of account book record is identical, first is verified；
It is less than or equal to assets account book address pair in the lower chain amount of assets of the lower chain assets information of lower chain solicited message The amount of assets of assets information on all chains answered, and the class of assets of the lower chain assets information of lower chain solicited message corresponding has When imitating the sum of efficient portfolio Board Lot of original block more than or equal to lower chain amount of assets, second is verified；
In the park assets classification of the park assets distribution request to lower chain original block block number and the support of lower chain assets information Pipe class of assets is identical, and the lower chain amount of assets of the lower chain assets information of lower chain solicited message is equal to lower chain original block block number Initial block message in park assets distribution request park assets distribution of information in the sum of efficient portfolio Board Lot when, the Three are verified.After above-mentioned verifying passes through, the lower chain solicited message with assets mandatory system signature is sent to Assets trusteeship party.
Step S207: assets trusteeship party verifies the lower chain solicited message with assets mandatory system signature, verifies By rear, will be returned in the lower chain assets information with lower chain solicited message to the corresponding park assets of lower chain trustship registration index information It also transfers the possession of to user.Assets trusteeship party, which can be, has certain qualification, mechanism with certain public credibility degree, such as commercial silver Capable and its operation system；Assets trusteeship party can be one for receiving the entity of park assets, can use the methods such as fund Rule relationship is set up；In some actual conditions, which can handle information using manual type.Specific verifying content packet Include: assets trusteeship party verifies the signature of the assets application terminal system in lower chain solicited message and the signature of assets mandatory system, And it is used when verifying the letter of identity in the corresponding real name account book record of lower chain solicited message with assets mandatory system registration assets The corresponding letter of identity of signature it is whether consistent.Verifying signature, for confirming that the lower chain solicited message is effective, credible；Verify body Part certificate applies under assets that the user of chain returns with this park assets that transfer the possession of the park assets in operating corresponding for determining User identity is consistent.
Since assets mandatory system has verified lower chain solicited message in step S206, therefore assets trusteeship party can Park assets, which are executed, with the content for the lower chain solicited message signed according to assets mandatory system returns transfer operation, specifically: money It is corresponding to user information is returned in lower chain solicited message that subrogation is handled in the trustship direction assets right registration system initiation of production The operation of user.Assets right registration system is assets right registration system traditional under chain.The operation can may also be related to one A little artificial or Below-the-line, depending on the specific operation flow of the assets right registration mechanism.
Embodiment two: it between step S202 and step S203, can also first be initiated that assets can be returned on chain by user Inquiry operation, user can determine lower chain amount of assets according to that can return assets on the chain inquired.It needs to guarantee lower chain money herein Quantity is produced to be less than or equal on the chain inquired that assets (being known as in the present embodiment to assets on the chain of lower chain) can be returned.On realizing Query process is stated, the system of chain also needs to include assets account book system under assets on the chain of the embodiment of the present invention, implements process It is as follows:
Fig. 3 is that the system of chain carries out the main flow signal of asset search on chain under assets on chain in the embodiment of the present invention two Figure.As shown in figure 3, the system of chain carries out the main flow of asset search on chain, packet under assets on the chain of the embodiment of the present invention two Include following steps:
Step S301: assets application terminal system shows asset search function interface on chain to user on the terminal device. Asset search function interface inputs and/or selects query requirement for user on the chain.
Step S302: user inputs in asset search function interface on chain and/or selects query requirement, to generate on chain Asset search solicited message.Asset search solicited message refers to that user, can for the digital asset of oneself cochain on the chain To initiate the request of digital asset inquiry.In an optional embodiment, asset search solicited message includes on the chain: described Assets account book address and the query requirement in real name account book record.The query requirement refers to that user carries out assets on chain and looks into Ask some limiting factors that may be used.In an optional embodiment, the query requirement includes: querying condition and inquiry knot Fruit, the querying condition can be following any one or multinomial: assets serial number, class of assets, Asset State etc..Wherein, The Asset State includes: effective status, frozen state, cancel status etc..
The query result can be following any one or multinomial: amount of assets, assets detail, initial block message, The corresponding park assets of block message, transaction in assets historical record, original block that terminate save information, the corresponding park assets of terminator block Save information etc..The original block information includes: original block block number, assets serial number, park assets registration index information, trustship money Produce description information, obligee address, assets distribution Board Lot, efficient portfolio Board Lot.The terminator block information includes: end Agglomerate the corresponding original block record list that terminated, terminator block block number, with storage service system signature update park assets Register index information.The park assets, which save information, may be considered assets under store in storage service system and chain Chain returns comprehensive trustship relevant, that confirmation assets trusteeship party is as park assets obligee under assets on trustship cochain or chain Assets information, in an alternate embodiment of the invention, it includes: paper document electronization or pure electronization that the park assets, which save information, Credential information (such as can be electronic signature achieve, or the result arrived by assets right registration system queries).
Assuming that the query requirement in the present embodiment includes initial block message, then assets application terminal system need to be from assets account book Obtained in system on corresponding with the assets account book address of asset search solicited message on the first chain chain assets information and with institute The corresponding initial block message of park assets classification for stating assets information on chain, is specifically shown in step S303.Assuming that in the present embodiment Query requirement in only include amount of assets, then assets application terminal system need to only be obtained from assets account book system and be provided on chain Produce assets information on the corresponding chain in assets account book address of inquiry request information.
Step S303: assets application terminal system accesses assets account book system, with acquisition and chain from assets account book system The corresponding transaction in assets information in assets account book address of upper asset search solicited message.Wherein, the transaction in assets packet It includes: assets information and initial block message corresponding with the park assets classification of assets information on the chain etc., the chain on chain Upper assets information include: assets account book address, park assets classification, amount of assets, on chain assets trustship registration index information and It is associated with assets information etc., the original block information includes: original block block number and the park assets with assets mandatory system signature Distribution request etc., the park assets distribution request include: the park assets registration index letter with storage service system signature Breath and park assets distribution of information etc., the park assets registration index information include: park assets registration index mark and support Pipe assets protect stored anti-tamper information etc., and the park assets distribution of information includes: that park assets classification, park assets are retouched State information, obligee address, assets distribution Board Lot etc..Assets application terminal system access assets account book system, inquiry with Assets information on the corresponding all chains in assets account book address, then be associated by the park assets Query of assets information on chain Initial block message；Query result is fed back to assets application terminal system by assets account book system.The anti-tamper information are as follows: support Pipe assets protect stored digital finger-print information, or are believed using assets mandatory system and storage service system the digital finger-print Cease the information after being signed.Digital finger-print information refers to that saving information progress operation to park assets using certain algorithm obtains Information, for example, saving information to park assets carries out obtained cryptographic Hash after Hash operation.It should be noted that number refers to Line information can also save information to park assets using other algorithms and carry out the information that operation obtains, as long as the letter that operation obtains The unique corresponding park assets of breath save information.
The realization of associated initial block message is inquired in assets information on the chain gone out by assets account book address lookup, backtracking Journey are as follows: (1) using according to the assets account book address lookup to chain on assets information as assets information after current transaction；(2) Transaction previous existence is inquired into the preamble assets information of assets information after the current transaction by assets information after the current transaction； (3) using the preamble assets information as assets information after the current transaction, step (2) are repeated, until inquire The preamble assets information is the park assets distribution of information for including in initial block message, and the initial block message inquired is institute State the initial block message for including in query result.
In two kinds of situation, one: one park assets classification of situation uniquely corresponds to an initial block message to above-mentioned query result, Two: one park assets classifications of situation correspond to multiple initial block messages.It is corresponding and if only if assets account book address for situation one Amount of assets it is identical as the efficient portfolio Board Lot of initial block message when, just can be to assets (this implementation on the chain of trustship It is known as park assets in example) carry out lower chain operation.For situation two, such assets can repeatedly increase after park assets mutually similar Assets (assets are alienable digital asset on the chain) on other chain, therefore a class of assets corresponds to multiple original block letters Breath；When the corresponding amount of assets in assets account book address is more than or equal to the efficient portfolio units of one or more initial block message When the sum of amount, assets on the chain of trustship can be carried out with lower chain operation, namely the once corresponding support of the multiple initial block messages of lower chain Pipe assets.
Step S304: assets application terminal system will belong to same trustship money according to the park assets classification inquired The amount of assets efficient portfolio Board Lot corresponding with initial block message for producing assets information on the chain of classification is compared, according to Comparison result is determined to assets on the chain of lower chain.This step is used for can the number returned of following chain according to the judgement of above-mentioned query result Assets.Lower chain is integrally to descend chain for the amount of assets of a class of assets, is the lower chain as unit of original block, thus It is required that lower chain amount of assets is equal with the sum of assets issuing amount in the initial block message of one group of same asset classification.Embodiment In, it determines to assets on the chain of lower chain: for situation one, assets on the corresponding chain of initial block message being made as follows For assets on the chain to lower chain；For situation two, according to the corresponding amount of assets in assets account book address, select one or Multiple initial block messages so that the sum of the corresponding efficient portfolio Board Lot of the initial block message of selection be less than or equal to it is described Amount of assets, using assets on the corresponding chain of the initial block message selected as assets on the chain to lower chain.
In a preferred embodiment, user is removed by assets application terminal system and obtains assets from assets account book system Outside Transaction Information, it may also need to obtain park assets and save information.Park assets save information preservation in storage service system, The system of chain also needs to include storage service system under assets on the chain of the corresponding embodiment of the present invention, and user sets in step S302 It needs to include that the corresponding park assets of original block save information in fixed query requirement.Storage service system in embodiment needs to pacify It is complete credible, it can be cloud storage service system, be also possible to the equipment with store function, be also possible to be had by more The system that the equipment of store function is formed by network connection.Step S305 is shown in specific implementation.
Step S305: assets application terminal system accesses storage service system, to register index mark according to park assets, Corresponding park assets are obtained from storage service system and save information, and it is stored anti-tamper to verify the park assets guarantor Information.Wherein, it includes: with assets application terminal system and the assets mandatory system that the park assets, which save information, The assets trustship cochain solicited message of doubled sign, and with assets application terminal system, the assets mandatory system and The assets right trustship transferable information of the assets trusteeship party tripartite signature.In optional embodiment, park assets save information The signature (doubled sign is anti-tamper information) of signature and storage service system with assets mandatory system, verifying are double Signature is for guaranteeing that information is not tampered with.Assets application terminal system accesses storage service system, inquiry and transaction in assets information Initial block message park assets distribution request in park assets registration index information in park assets registration index mark Sensible corresponding park assets save information；Query result is fed back to assets application terminal system by storage service system.
The assets trustship cochain solicited message includes: having assets application terminal system and assets trustship system Solicited message, park assets distribution of information and assets trusteeship party information etc. are transferred the possession of in assets trustship under the chain of system doubled sign.Trustship money Distribution of information when distribution of information refers under chain in assets trustship to chain is produced, assets trusteeship party information refers to responsible trustship distribution The information of the assets trusteeship party of assets under chain on to chain.In an alternate embodiment of the invention, assets trustship transfer is requested under the chain Information includes: that request instruction is transferred the possession of in assets trustship under the chain with assets application terminal system signature and real name account book is remembered Record.It includes: assets register information and the trustship transfer assets amount of money or quantity under chain that request instruction is transferred the possession of in assets trustship under the chain, Assets register information refers to which assets information under the chain that user registers in assets right registration system, such as user possess under chain Whether the related status information of the assets of type, the amount of money of each type assets or quantity, assets is (for example whether pledging, depositing a bit In flaw etc.) etc.；The assets amount of money is transferred the possession of in trustship or quantity refers to, the amount of money or number of assets under the chain of user's request trustship transfer Amount.In an alternate embodiment of the invention, under chain assets register information include: assets right registration system access address and asset identification Information etc., the asset identification information include: identity, asset identification or number, the assets amount of money or quantity of user etc..
The assets right trustship transferable information includes: assets subrogation credential information, assets trusteeship party holding assets Credential information, update chain under assets register information and other assets description and register information.
In a preferred embodiment, in order to preferably show the information obtained to user, step S203 be could alternatively be Following process: assets application terminal system saves assets information, initial block message, park assets on the corresponding chain of class of assets Information and lower chain operation entry show user by terminal device.Assets application terminal system is by each class of assets pair Assets information, initial block message, park assets save information on the chain answered and lower chain operation entry shows user.
In a preferred embodiment, user is removed by assets application terminal system and obtains assets from assets account book system Outside Transaction Information, it may also need to obtain assets register information under chain.Assets register information is stored in assets right registration under chain System, the system of chain also needs to include assets right registration system under assets on the chain of the corresponding embodiment of the present invention, and step It needs to include assets register information under chain in query requirement set by user in S302.Step S306: assets application is shown in specific implementation Terminal system local IP access assets right registration system, to be registered from assets under the chain for obtaining user in assets right registration system Information.Wherein, the assets right registration system provides the api interface of assets rights verification inquiry, and assets are registered under the chain Information includes: asset identification or number, the assets amount of money or quantity etc..Assets application terminal system accesses assets right registration system System, inquires assets register information under the chain of user；Query result is fed back to assets application terminal system by assets right registration system System.The step is used for from assets register information under the chain that inquiry user holds in the assets right registration system under chain.It needs to infuse Meaning, what the embodiment of the present invention did not limit the step executes sequence, the execution after step S302.
Embodiment three: in step S206, the lower chain solicited message with assets mandatory system signature is sent to assets Before chain is returned under trusteeship party, it is also necessary to confirm that the corresponding park assets of initial block message save information and currently in assets right The information registered in register system is consistent, to ensure that trusteeship party has the right the corresponding park assets of the initial block message returning to use Family.It is implemented as follows:
Fig. 4 is that the main flow that the system of chain carries out consistency on messaging confirmation under assets on chain in the embodiment of the present invention three is shown It is intended to.As shown in figure 4, the system of chain carries out the main stream of consistency on messaging confirmation under assets on the chain of the embodiment of the present invention three Journey, comprising the following steps:
Step S401: assets mandatory system is according to chain assets information lower in lower chain solicited message to lower chain original block block Number, the park assets registration index mark in corresponding initial block message is obtained, the park assets are registered into index mark and are passed through Inquiry request is sent to storage service system.Assets mandatory system obtains corresponding original block letter according to lower chain original block block number Breath, the park assets of the park assets registration index information of the park assets distribution request based on the initial block message of each of acquisition Registration index mark inquires corresponding park assets to storage service system and saves information.
Step S402: storage service system is inquired according to the park assets registration index mark in inquiry request to lower chain The corresponding park assets of original block block number save information, and the park assets inquired preservation information is fed back to assets trustship later System.
Step S403: park assets preservation information is sent to assets trusteeship party by assets mandatory system, and request is weighed with assets Sharp register system carries out verification verifying.
Step S404: assets trusteeship party accesses assets right registration system, and inquires and check the park assets received Information is saved, to judge that it is corresponding with assets right registration system that park assets protect stored assets right trustship transferable information Whether information is consistent, if unanimously, thening follow the steps S405；If inconsistent, S406 is thened follow the steps.
Step S405: the lower chain solicited message signed with assets trusteeship party is sent to assets trustship system by assets trusteeship party System, and request to carry out lower chain freezing of assets operation.In the above process, the park assets of storage service system are saved into information and money The information of property right benefit register system compares, if the two is consistent, is verified, and assets trusteeship party has the right to request to believe by lower chain The assets specified in breath are returned to user.Assets application terminal system, assets trustship system are had in lower chain solicited message at this time System and assets trusteeship party tripartite signature.
Step S406: assets trustship direction assets mandatory system returns to the notice of lower chain operation failure.It, will in the above process The information that the park assets of storage service system save information and assets right registration system compares, if the two is inconsistent, Illustrate that exception, lower chain operation failure occurs in trustship process.
In a preferred embodiment, after step S403 is finished, park assets can also be confirmed by assets trusteeship party Whether the asset owner saved in information in assets right trustship transferable information is the assets trusteeship party.If asset owner is not It is the assets trusteeship party, then the assets trusteeship party haves no right the assets specified in lower chain solicited message being returned to user, to assets Mandatory system returns to the notice of lower chain operation failure.
Example IV: during guaranteeing that assets are returned, lower chain assets in the lower chain assets information of lower chain solicited message The corresponding park assets of index record (being known as lower chain assets in the present embodiment) no longer carry out other with corresponding initial block message Operation, needs to freeze lower chain assets and the corresponding initial block message of lower chain assets, to ensure that lower chain refund operation can Normally to execute.Specific implementation needs the assets on the chain that step S206 saves lower chain solicited message, assets account book system to believe After breath and initial block message are verified, and the lower chain solicited message for having assets mandatory system signature is being sent to money Before producing trusteeship party, following treatment process is executed:
Fig. 5 is that the system of chain carries out the main flow schematic diagram of the freezing of assets under assets on chain in the embodiment of the present invention four. As shown in figure 5, the system of chain carries out the main flow of the freezing of assets, including following step under assets on the chain of the embodiment of the present invention four It is rapid:
Step S501: it after assets mandatory system verifies the signature of lower chain solicited message, is sent to assets application terminal system Lower chain solicited message with tripartite's signature, and the lower chain freezing of assets operational order with assets mandatory system signature.Its In, the lower chain freezing of assets operational order includes: to freeze command information, with assets application terminal system and assets trustship system The lower chain solicited message etc. of system doubled sign；The command information that freezes can indicate main in lower chain freezing of assets operational order Information, in an alternate embodiment of the invention, the command information that freezes includes: to freezing of assets, freezing of assets transaction and surplus assets Transaction etc., it is described to refer to registering index information to lower chain trustship in the lower chain assets information of lower chain solicited message to freezing of assets In whole under chain asset inventory.The step is used to carry out lower chain freezing of assets operation to assets application terminal system request.
Step S502: it after assets application terminal system verifying signature, is sent to assets account book system and has assets trustship system The lower chain freezing of assets operational order of system signature.Assets application terminal system verifies lower chain solicited message, lower chain freezing of assets behaviour After making the signature instructed, the lower chain freezing of assets operational order signed with assets mandatory system is sent to assets account book system.
Step S503: the signature of chain freezing of assets operational order, lower chain solicited message under assets account book system individual authentication Signature and lower chain freezing of assets operational order freeze command information after, according to freezing for lower chain freezing of assets operational order Command information treats freezing of assets and carries out freezing to handle, and records freezing of assets transaction and result assets.To freezing command information Verifying specifically: freeze the class of assets of the result assets of freezing of assets transaction and surplus assets transaction in command information under The park assets classification of lower chain assets information is identical in chain freezing of assets operational order, and the sum of amount of assets is believed with lower chain assets The lower chain amount of assets of breath is identical.
In a preferred embodiment, the verification operation that assets mandatory system is carried out in step S206 can also be carried out. The verification operation of the step is completed by node of knowing together on the chain of assets account book system, after being proved to be successful, is held by node of knowing together on chain The operation of the row freezing of assets, and record freezing of assets transaction.
Step S504: assets application terminal system is recorded according to real name account book, is searched in assets account book system wait freeze The account book address of assets and the corresponding all stock assets of park assets classification and historical trading assets, to obtain freezing of assets behaviour Make result information.Wherein, the freezing of assets operation result information includes: account book address, class of assets and the jelly of freezing of assets Tie assets information etc.；The freezing of assets information can indicate the jelly generated after performing lower chain freezing of assets operational order The main information in Asset operation result is tied, may include: frozen assets, freezing of assets quantity, freezing of assets recording indexes With surplus assets recording indexes etc..
Step S505: assets application terminal system verifies the freezing of assets operation result information of acquisition, and verifying is logical Later, the freezing of assets operation result information with assets application terminal system signature is sent to assets mandatory system.It has The freezing of assets operation result information of assets application terminal system signature, it is believed that be freezed for lower chain assets At rear generation, result information by the system authentication of assets application terminal.The content of verifying includes:
Assets and lower chain freezing of assets operational order are frozen in the freezing of assets information of freezing of assets operation result information Freeze it is identical to freezing of assets in command information；
Freezing of assets quantity refers to the operation of the lower chain freezing of assets in the freezing of assets information of freezing of assets operation result information The lower chain amount of assets of lower chain assets information is identical in the lower chain request instruction enabled；
Freezing of assets recording indexes and surplus assets record rope in the freezing of assets information of freezing of assets operation result information Draw the content phase with the freezing of assets transaction freezed in command information in lower chain freezing of assets operational order and surplus assets transaction Symbol.
The step for notifying the assets mandatory system freezing of assets to complete, handle park assets and return by request assets mandatory system Also transfer the possession of.It is provided correspondingly, assets mandatory system can will receive the freezing of assets operation result information as that will handle trustship Produce the commencing signal returned and transfer the possession of operation.
Step S506: it after assets mandatory system verifying signature, is inquired in assets account book system and verifies freezing of assets behaviour Make result information.After assets mandatory system verifying signature, voluntarily queries asset account book system, with the real name account of assets account book system Subject to this record, freezing of assets result is checked.Assets mandatory system obtains freezing of assets operating result from assets account book system After information, verified in the way of step S505.
Embodiment five: it after park assets are returned to user (i.e. step S207), also needs to provide under the chain after return assets It produces register information to update into assets mandatory system, such assets mandatory system can completely retain the whole of assets return Process, it can include the assets that the park assets returned on subsequent chain to lower chain, which cancel in the termination block message that operation is formed, The return transferable information of mandatory system registration.The information update process is to solve assets on existing block chain to be completely dependent on block Chain, can not by assets from chain transfer to chain under problem in important step.It is implemented as follows:
Fig. 6 is that the system of chain carries out the main flow schematic diagram of information update under assets on chain in the embodiment of the present invention five. As shown in fig. 6, the system of chain carries out the main flow of information update, including following step under assets on the chain of the embodiment of the present invention five It is rapid:
Step S601: the park assets signed with assets trusteeship party are returned transfer completion information and sent by assets trusteeship party To assets mandatory system.Wherein, it includes: the lower chain request letter with tripartite's signature that the park assets, which are returned and transfer the possession of completion information, Breath, confirmation complete park assets and return transferable information and park assets return transferable information, and park assets herein, which are returned, to be transferred the possession of Information is identical as the assets right trustship transferable information of step S305.Lower chain solicited message is with assets application terminal system, money Mandatory system, assets trusteeship party tripartite signature are produced, the information can be made safer credible.It should be noted that assets trustship System is possible to not identify that park assets return the credential information of transferable information, and the present embodiment is built upon assets mandatory system On the basis of trusting assets trusteeship party, subsequent user can voluntarily inquire park assets and return transferable information to be verified.
Step S602: it after assets mandatory system verifying signature, returns to transfer the possession of in park assets and completes to add assets in information The signature of mandatory system generates new park assets later and saves information and be uploaded to storage service system.Assets mandatory system is tested After the signature of card assets trusteeship party, returns to transfer the possession of in park assets and complete to add itself signature in information, and be based on asking on lower chain It asks information and park assets to return and transfers the possession of the new park assets preservation information of completion information generation, be uploaded to storage service system later System.The step saves information for the more park assets of new assets mandatory system and storage service system.
New park assets save information on the basis of original park assets of storage service system save information, increase Lower chain solicited message, park assets return transferable information, and park assets return transferable information is attached to assets right support After pipe transferable information, the overall process information of assets trustship and return thus can be completely retained in mandatory system, is convenient for It is subsequent to be inquired.In an alternate embodiment of the invention, it includes: that original park assets save letter that the new park assets, which save information, Breath, the lower chain solicited message with tripartite's signature, the park assets with assets trusteeship party and assets mandatory system doubled sign return Also transferable information etc..In embodiment, according to lower chain solicited message to lower chain original block block number, the distribution of each initial block number is asked Corresponding park assets preservation information, storage service system meeting can be retrieved by asking the park assets in information to register index information Park assets return transferable information is added to park assets to save in information.
Step S603: storage service system sends out the new park assets registration index information signed with storage service system It send to assets mandatory system.Park assets registration index in new park assets registration index information identifies corresponding park assets It saves to update in information and increases park assets return transferable information, and have updated park assets and protect stored anti-tamper letter Breath.
Step S604: assets mandatory system registers the park assets registration index mark of index information according to new park assets Know, inquire new park assets preservation information to storage service system and verifies.Verifying content includes: the new support of assets mandatory system Pipe assets protect stored anti-tamper information and the new park assets preservation information of the storage service system by inquiring is calculated Whether anti-tamper information out is consistent；And the storage service system inquired new park assets save information in whether include Park assets return transferable information.If the new park assets that include in assets mandatory system protect stored anti-tamper information with It is identical according to the new park assets preservation calculated anti-tamper information of information of storage service system, illustrate storage service system New park assets save information and are really not tampered with.
Embodiment six: it after park assets are returned to user (i.e. step S207), also needs to cancel freezing of assets.The process The middle digital asset freezed on chain before transfer that will return has carried out cancelling operation, and is based on the corresponding original block of freezing of assets Information generates termination block message, which is terminated original block recording indexes and storage service system updates Return transferable information afterwards, realizes the final state of assets on chain, is properly completed on chain chain under assets and operates.It implemented Journey is as follows:
Fig. 7 is that the system of chain carries out the main flow signal of freezing of assets calcellation under assets on chain in the embodiment of the present invention six Figure.As shown in fig. 7, the system of chain carries out the main flow of freezing of assets calcellation, packet under assets on the chain of the embodiment of the present invention six Include following steps:
Step S701: assets mandatory system submits the lower chain assets signed with assets mandatory system to assets account book system Cancel operational order.Wherein, the lower chain assets cancel operational order and include: class of assets, cancel assets information, is to be terminated Original block block number and the new park assets registration index information with storage service system signature etc., the calcellation assets information packet It includes: assets, amount of assets to be cancelled and calcellation transaction in assets to be cancelled etc..
Step S702: after assets account book system verifies lower chain assets calcellation operational order, cancel according to lower chain assets and operate Instruction treats calcellation assets and carries out calcellation processing, and records and cancel transaction in assets, result assets and termination block message.Terminator block Correspond to what frozen original block generated, for the last one transaction of lower chain digital asset transaction.Verifying content includes:
Node disjoint of knowing together on the chain of the assets account book system verifies the signature that the lower chain assets cancel operational order；
Whether the letter of identity of the assets account book system has the right to carry out calcellation operation to the assets to be cancelled；
The lower chain assets cancel operational order class of assets and the freezing of assets operation result information that inquires Class of assets is identical；
Cancel the assets to be cancelled and the freezing of assets operation result information of transaction in assets in the calcellation assets information The freezing of assets quantity of middle freezing of assets information is consistent with freezing of assets recording indexes；
The amount of assets to be cancelled of calcellation transaction in assets and the freezing of assets operating result in the calcellation assets information The freezing of assets quantity of freezing of assets information is consistent in information；
The original block block number to be terminated with tripartite signature lower chain solicited message in lower chain assets information to Lower chain original block block number is identical；And
Verify the signature and the new park assets registration index information pair of the new park assets registration index information The new park assets answered protect stored anti-tamper information.The above verifying can determine lower chain assets cancel operational order itself with And instruction in various information accuracy, improve in the embodiment of the present invention cancel operating process safety.
Step S703: assets mandatory system cancels the money of operational order according to the account book address and lower chain assets of cancelling assets Classification is produced, first is obtained from assets account book system and cancels Asset operation result information, cancels Asset operation according to first later The terminator block block number of termination block message in result information returns to corresponding terminator block and records information.First cancels Asset operation knot Fruit information is to execute lower chain to return the result obtained after assets calcellation operational order.In optional embodiment China, described the One calcellation Asset operation result information includes: the account book address for cancelling assets, class of assets, cancels assets information, terminator block letter Breath etc., the calcellation assets information include: by calcellation assets, cancel amount of assets and calcellation asset inventory index etc., the end Information of agglomerating includes: the original block block number being terminated and terminator block block number etc..Terminator block record information includes: block number, just Beginning block recording indexes and the new park assets registration index information with storage service system signature etc., the original block recording indexes It include: block number and original block record Hash information etc..
Step S704: after Asset operation result information is cancelled in assets mandatory system verifying first, to assets application terminal system System sends the first calcellation Asset operation result information with assets mandatory system signature, and signs with assets mandatory system Park assets return transfer the possession of complete information.Assets trusteeship party and assets support are had in calcellation Asset operation result information herein Guard system both sides signature.Verifying content includes:
The assets phase to be cancelled for being cancelled operational order with the lower chain assets by calcellation assets for cancelling assets information Together；
The calcellation amount of assets for cancelling assets information and the lower chain assets cancel the assets to be cancelled of operational order Quantity is identical；
The calcellation asset inventory for cancelling assets information indexes corresponding calcellation assets and quantity and described cancelled provides It produces corresponding with quantity；
The original block block number being terminated in the termination block message is cancelled in operational order with the lower chain assets wait terminate Original block block number it is identical；
The terminator block block number of the termination block message is corresponding with the terminator block record block number of information；
The list and the lower chain assets that block number in the original block recording indexes of all terminator block record information is formed The list for cancelling the original block block number formation to be terminated of operational order is identical；
Correspond in the original block recording indexes of each terminator block record information the original block record Hash information of block number with it is first The content verification of beginning block message is consistent；And
It is described termination block message with storage service system signature new park assets registration index information and it is described under The new park assets registration index information with storage service system signature that chain assets cancel operational order is identical.By upper It states after multiple-authentication passes through, it is believed that the calcellation operation to freezing of assets on chain under assets in chain process is correct 's.
The step for notifying assets application terminal system, return assets on transfer completion and chain and cancelled by park assets At.
Embodiment seven: assets on chain can also inquire lower chain and return as a result, such as looking into after lower chain is returned to user The digital asset and updated park assets for asking the digital asset, calcellation held on current chain save information.Specific implementation Process is as follows:
Fig. 8 is that the system of chain carries out the main flow signal of lower chain result queries under assets on chain in the embodiment of the present invention seven Figure.As shown in figure 8, the system of chain carries out the main flow of lower chain result queries under assets on the chain of the embodiment of the present invention seven, packet Include following steps:
Step S801: the signature and trustship money of Asset operation result information are cancelled in assets application terminal system verifying first It produces after returning the signature for transferring the possession of completion information, the assets information cancelled in queries asset account book system；According to first received Cancel stock assets and historical trading assets that Asset operation result information searches assets mandatory system, obtains second and cancel assets Operation result information, and judge whether the send with assets mandatory system first calcellation Asset operation result information is consistent.
