It, should as shown in FIG. 1, FIG. 1 is the present invention is based on the flow diagram of one embodiment of assets exchanging method of block chain Assets exchanging method based on block chain the following steps are included:
Step S1, the client of terminal receive the financial digital asset redemption information of the typing in operation interface, to initiate Financial digital asset is converted to and unifies integral or the exchange trading by unification accumulated point exchanging for legal tender, utilizes the client The encrypted credentials at end are that the exchange trading generates signature, which is sent at least one scheduled endorsement node;
Wherein, each company for providing financial digital asset exchange or mechanism are capable of providing client and carry out financial number for user Word assets are exchanged, which exchanges are as follows: the financial digital asset such as card certificate is converted to the product of the unified distribution of the said firm Point, or will unify accumulated point exchanging is legal tender (for example, RMB etc.).The finance digital asset redemption information includes mechanism Square title (or Business Name), the user name of exchange side, the type of assets and quantity;Wherein, the type include: unified integral, Bank card integral, insurance company are insured amount, mobile communication connection supplements telephone expenses with money or give integral, supermarket shopping card, restaurant food and drink certificate, Gymnasium body-building card, barber shop's hairdressing certificate.
Wherein, when initiating exchange trading, the encrypted credentials using client are that the exchange trading generates a signature, are led to The Java SDK (Java Software Development Kit, Java software development kit) for crossing client goes to call API Interface is sent to one or more scheduled endorsement node, which can be same Mechanism, it is also possible in different institutions.When initiating exchange trading, the intelligence conjunction to be called with this exchange trading About mark, method, the financial information such as digital asset redemption information and client signature are sent to endorsement node.
Step S2, the signature of the endorsement node verification client, and the finance digital asset is based on after being verified Redemption information executes the intelligent contract on block chain to carry out mock trading, and the result of mock trading is stamped endorsement signature, is returned The result of endorsement signature is returned to the client;
Node endorse after receiving the exchange trading, whether the signature for verifying the client is effective, i.e., whether is legal Signature, be then verified if it is legal signature.
It include the various rules or agreement that each mechanism side promises to undertake in intelligent contract, including converting in intelligent contract in the present embodiment Change rule.Endorsing node can be when calling intelligent contract using the financial digital asset redemption information in the exchange trading as parameter Incoming, intelligent contract removes processing exchange trading knot according to the data of financial digital asset redemption information and current account book database Fruit, the transaction results are mock trading as a result, if this exchange trading is allowed to, which contains: return code, The data acquisition system of reading or the data acquisition system (this write operation will not temporarily execute database) of write-in, at this moment will not will be right Account book is updated, because the exchange trading does not complete the whole network common recognition.The data acquisition system of reading is the corresponding data of inquiry operation, The data acquisition system of write-in is the corresponding data of operation for needing to keep accounts.The present embodiment does not include the data acquisition system read but only wraps Data acquisition system containing write-in, the data acquisition system of write-in include mechanism side's title, the user name of exchange side, the class of financial digital asset Type and quantity.Then these return to client by the signature of intelligent contract treated transaction results can take endorsement node together The Java SDK program at end, the JavaSDK program of client can parse these data, are supplied to client and do processing in next step.
Whether step S3, the client meet scheduled endorsement plan based on the result inspection endorsement for stamping endorsement signature Slightly, if satisfied, then obtaining transaction details based on the result for stamping endorsement signature, if the client can call directly sequence clothes The transaction details of the exchange trading are then broadcasted in business to sequence service node;
If the client cannot call directly sequence service, the transaction of the endorsement node broadcasts exchange trading is believed in detail Breath, to broadcast the transaction details of the exchange trading to sequence service node by the endorsement node;
Whether the signature for the endorsement node that client can go verifying to assure is correct, and compares exchange trading and mock trading As a result whether consistent.Due to being exchange trading rather than inquiry transaction, client attempts that exchange trading is submitted to give sequence clothes Node be engaged in update account book.Be necessary to ensure that before submission it is all endorsement nodes signatures all collect it is complete, that is, be based on the back Whether the result inspection endorsement of bookmark name meets scheduled endorsement strategy, for example, scheduled endorsement it is tactful for T (2, " A ", " B ", " C "), indicate that client needs to collect the endorsement signature of any 2 endorsements node in A, B, C;For another example, scheduled endorsement strategy is T (1, " A ", T (2, " B ", " C ")) indicates the signature needed collection from endorsement node A or from both endorsement node B and C Signature endorsement.
If client illustrates that the exchange trading has passed through endorsement rank after checking and meeting scheduled endorsement strategy Section, then obtain transaction details based on the result for stamping endorsement signature, which includes the data acquisition system of write-in And endorsement signature of endorsement node etc..
If client can call directly sequence service, the transaction for broadcasting the exchange trading to sequence service node is detailed Information;If the client cannot call directly sequence service, above-mentioned endorsement node broadcasts exchange trading can choose, These endorsement nodes must will not remove any message or other friendships that may be deactivated from endorsement signature by client trust Easily, to pass through the transaction details of these endorsement node broadcasts exchange tradings to the service node that sorts.
If client is unsatisfactory for scheduled endorsement strategy checking, this exchange trading is abandoned, it later can be with Selection re-initiates exchange trading.
The exchange trading is ranked up and is packaged block by step S4, the sequence service node, and is submitted this to exchange and handed over Easy block is to the endorsement node, so that the endorsement node records this exchange trading on block chain account book;
Step S5, which monitors the endorsement node, after listening to the event of this exchange trading, parses the event Corresponding feedback information, to determine whether this exchange trading is recorded on block chain account book.
Wherein, sequence service node not can read the transaction details of exchange trading, but only from all in network The channel reception exchange trading, is in chronological order ranked up it, and creates exchange trading block, exchange trading for each channel Block is passed on the endorsement node on channel.
On endorsement node, the transaction in exchange trading block is verified to be satisfied with the strategy that ensures to endorse, exchange trading block In transactional marking be it is effectively or invalid, the transactional marking in the exchange trading block of the exchange trading is effectively that then this is converted It is effective for changing transaction, it is believed that this exchange trading is the whole network common recognition.Node endorse for each effective exchange trading, is somebody's turn to do The data acquisition system of write-in in transaction details is submitted to current status data library, so as to the minute book on block chain account book Secondary exchange trading, concurrent outgoing event is to notify client.
Wherein, client monitors the endorsement node, knows this by the corresponding feedback information of the event of this exchange trading Whether secondary exchange trading is recorded on block chain account book, in addition, if be invalid exchange trading, it equally can be from feedback letter Know in breath.
In the present embodiment, the data acquisition system of the write-in in the transaction details is submitted to current status data library (back Have levelDB database on book node, store the data of user, data of company etc.), user is requested to the finance number exchanged Assets are exchanged, i.e., data, the data of company of user are obtained from database, according to the finance number of this exchange trading The type and quantity of assets update the data of the user, the data of company, and assets are divided into the account of user.
Compared with prior art, the present invention is based on block chain technologies to construct financial digital asset exchanging platform, passes through platform The intelligent contract disposed and reached common understanding on block chain is about scheduled on each company, and is constructed JavaSDK micro services and applied (i.e. client Hold corresponding application), it goes to call intelligent contract-defined interface by Java SDK, complete to the reading and writing data on block chain account book, it is real Financial digital asset is now converted into unified integral or it is legal tender by unified accumulated point exchanging, the assets deposit after exchange is flat Personal account in platform, financial digital asset exchanging platform of the invention are flowed for the financial digital asset in each mechanism side It is logical, it realizes the intercommunication of financial digital asset, improves the utilization rate of financial digital asset, while each machine of block chain technical guarantee Safety problem between structure side.
In a preferred embodiment, mechanism can improve the unified integral of distribution by way of house call, The flexibility of platform application is improved, as shown in Fig. 2, on the basis of the above embodiments, the assets based on block chain are exchanged Method, further includes:
Step S101, the client receive the recovery information of the house call of typing in operation interface, to initiate to mention The adjustment transaction of the amount of the unified integral of the corresponding mechanism side's distribution of height, is adjustment transaction using the encrypted credentials of the client Signature is generated, adjustment transaction is sent at least one scheduled endorsement node, for the endorsement node verification signature, is being tested Card based on the recovery information executes the intelligent contract on block chain after passing through to carry out mock trading, and by the result of mock trading Endorsement signature is stamped, the result of the mock trading for stamping endorsement signature is returned into the client, which includes House call proves the amount of information and unified integral to be improved;
Step S102, it is pre- whether which is met based on the result inspection endorsement for stamping the mock trading of endorsement signature Fixed endorsement strategy, if satisfied, the result then based on the mock trading for stamping endorsement signature obtains the detailed letter of integral adjustment Breath broadcasts the details that the adjustment is traded to sequence service node if the client can call directly sequence service, so as to Adjustment transaction is ranked up and is packaged block by the sequence service node, and submits the block of this adjustment transaction to the endorsement Node records this adjustment transaction for the endorsement node on block chain account book;
Step S103, the client monitor the endorsement node, after the event for listening to this adjustment transaction, parse the thing The corresponding feedback information of part, to determine whether this adjustment transaction is recorded on block chain account book.
Further, mechanism side's super generating is unified in order to prevent integrates, and ensures the purchasing power of unified integral and the safety of transaction Property, it is above-mentioned that intelligent contract on block chain is executed to include: the step of carrying out mock trading based on the recovery information
Whether the sum of guarantee fund that the current all mechanisms of analysis are paid, which is more than or equal to, is previously recorded in block chain account book Maximum guarantee fund's amount;
If it is greater than or equal to maximum guarantee fund's amount, then refuse this adjustment transaction;
If being less than maximum guarantee fund's amount, analyzes and own in the amount and the block chain of the unified integral to be improved Whether the sum of issued unified integral amount in mechanism side is greater than the unified integral volume of the maximum being previously recorded in block chain account book Degree;
If more than the unified integral amount of the maximum, then refuse this adjustment transaction;
If being less than or equal to the unified integral amount of the maximum, according to recovery information simulation, this adjustment is traded, and obtains the mould The result of quasi- transaction.
Wherein, the unified product of the maximum of finance digital asset exchanging platform initialization within a preset time (for example, in 1 year) Share degree and maximum guarantee fund's amount, for example, maximum unified integral amount is 10,000,000 integrals, maximum guarantee fund's amount is 1000 Ten thousand yuans, then one yuan correspondence one unified integral.Each mechanism side pays guarantee fund, counts all mechanism sides The full amount of the guarantee fund paid, such as the full amount of guarantee fund paid of all mechanism sides are 9,000,000 yuan and (still have 1,000,000 yuan Spare space), then the unified integral summation that all mechanism sides can issue is that 9,000,000 unified integrals (still have 1,000,000 unifications The spare space of integral).For example, the mechanism side A pays 1,000,000 guarantee fund, then distributing to the unified product of mechanism side distribution Point-score is 1,000,000 unified integrals.
After block chain is added in mechanism side, certain initial margin is paid, the third party that can be stored in regulatory agency's node (prevent certain mechanism side's super generating integral or break to the unified integral restricted by putchasing power of platform) in account, it is initial according to this The amount of guarantee fund initializes to obtain the unified integral of the said firm's distribution.
The amount of the unified integral of distribution, the current total guarantor of analysis block chain are improved if there is mechanism side's house call Whether card gold reaches maximum value (such as 10,000,000 yuan), if having reached the maximum value, does not allow to pay guarantee fund and not again Super generating is allowed to integrate, it, can be with recovery if not reaching maximum value.The unified integral of each mechanism side's distribution, is exchanged card certificate The write-in block chain account book such as the exchange rate in, prevent from distorting.
Wherein, above-mentioned that the step of intelligent contract on block chain is to carry out mock trading is executed based on the recovery information, into One step includes: the liveness that unified integral is exchanged by each mechanism side of statistics, if there are two or more than two mechanism sides initiate to mention The adjustment transaction of the amount for the unified integral that height is issued, then allow the adjustment of the highest mechanism side of liveness to trade, and refusal removes should The adjustment of other mechanism sides outside the highest mechanism side of liveness is traded.
Wherein, if (for example, 1 hour) has multiple mechanism sides to initiate adjustment transaction, basis in a period of time The liveness of unified integral is exchanged to determine that the adjustment transaction of which mechanism side is allowed transaction.Liveness is based on exchange Number, exchange amount of assets determine that the number of the exchange of mechanism side is more, the amount of assets exchanged is bigger, then liveness It is higher, conversely, then liveness is lower.In this way, so that exchanging active mechanism side obtains the unified product more issued Point, further improve the utilization rate of financial digital asset.
