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

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

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.
